98 eclipse gst question
 

i have a 98 gst that i am working on. the owner wants a bov but through reading through the forum i see there are different types of bovs. what is the best for this car sound and surge wise. it is completly stock except for the rims bu tthat dont make a diffence. intake and exast will follow but he want the bov first for some reason unknown to me. also is 3 inch exhaust recomended for turbod cars

Re: 98 eclipse gst question
 

let me reprase this a little. he wants it to sound good for a low price what is the best this i can do. does he need to get a bov or is there someway of makiing the stock one sound different.

Re: 98 eclipse gst question
 

Vortec Mondo. DOO EEET.

Re: 98 eclipse gst question
 

BOV on a dsm is a moot point since the vehicle rarely runs long enough to hear said bov.

Joking. But in all seriousness. Really.

Dsm's are mechanic's cars. If your doing the work on it, I hope your charging him...

To answer your question, the bov really doesnt make a damn bit of difference, since anything is better than the stock 2g bov. For sound, his ricer ass should look into an RFL, since thats all they are good for. For function, 1g dsm, evo MR bypass valves are an excellent choice. Venting to the atmosphere isnt a big deal on the 2g's the computer compensates for the most part, and wont stall out. It will still run rich between shifts but not nearly as bad as a 1g.

Re: 98 eclipse gst question
 

so i can take the tube off that runs the bov back into the intake and it will sound better is that what your tying to get at. i dont have to much experiance with modifying turbo cars just stock replacement stuff. and i plug up that tube on the intake. sounds simple enough though. but should i change it to a different bov.

Re: 98 eclipse gst question
 

Recirculate that bitch. Dont vent.

It's hit or miss wether or not the car will run like ---- with it venting.

The maf reads the air that passes through it at the start of the intake cycle. When it reads a different amount at the end of the intake cycle it sends that info to your pcm and your car ends up running like ass.

You need a gm maf and a gm maf translator in order to vent properly w/o running into problems.

Re: 98 eclipse gst question
 

It'll always be muffled when recirculated, BUT to make that MAF happy it's necessary. GST with a Greddy type s sounds pretty decent... I think the RFL is louder though (if that's all he's interested in).

Re: 98 eclipse gst question
 

Please spare the fellow hmt members in your area and don't run the queef sounding blow off valves that all the ricers run. >:(

Re: 98 eclipse gst question
 

ricers have turbo? or are you talkin about that "turbo simulator" that they mount inside of their muffler. lol

rfl for noise! or an ebay bov sounds good too since they make a replica of almost everything.
tell your customer dude to go ton youtube.com and type in "bov" or "blow off valve". start listening to sound clips and choose whatever he likes.

Re: 98 eclipse gst question
 

Not the turbo simulator, but the strange queef whistle that makes the car loose any balls it may have. Open downpipes and the like are preferred but to each his own.

Off topic but have you all heard the new detroit diesel engines with the power recovery turbine that was recently augmented? Sounds similar to a gas turbine and not a traditional diesel. I have searched youtube to no avail.

Re: 98 eclipse gst question
 

Just switch it over to a 1G BOV. The stock 2G BOV is plastic and will leak at any sort of real bost levels. The 1G is metal and holds boost fine. You absolutely have to recirculate your BOV if you're on the stock draw through MAF. Tell him if he wants a loud BOV he'll have to either get a GM MAF and a translator box (hack ass upgrade) or run a standalone and convert to speed density. Also, an intake and exhaust really won't do very much on a 2G because the stock turbo is very tiny. The biggest restriction in a 2G is the tiny stock T25's turbine wheel.

A metal intake tube and metal intercooler piping (or fmic) will make his coveted BOV louder, but power wise it won't do much. Before anything you guys should get a datalogger. Then swap out that stock plastic BOV for a 1G unit. Then you'll need to upgrade that T25. Even going to a 14b off the 1G cars is a significant upgrade, but a 16g or bolt-on Garrett would be better. You'll then need to address fueling and tuning components. DSMLINK is very cost effective and does the trick. I'd look to get at least 550cc injectors in there, but if you have DSMLINK or AEM EMS; the bigger the better (to a point). If you both don't know ---- about DSM's and the owner's main goal is to have a loud wooooosh then the car is doomed anyway and will be a hacked pile of garbage in no time like all the other DSM's that have fallen in broke rookie ricer's hands.

Re: 98 eclipse gst question
 

i worked on a 2g dsm as a professional and every contact point of the bov was jb weld.

Re: 98 eclipse gst question
 

so in translation it is really strong

Re: 98 eclipse gst question
 

You and your buddy should grab a couple ropes. If you care about the bov sound your a douche.

Re: 98 eclipse gst question
 

my focus runs a maf and i dont recirculate the bov, the key is to adjust the bov so it wont open that easily. you might get some surge but to bov wont stay open long just for a brief second.

and shooting flames is ------- awsome :y

Re: 98 eclipse gst question
 

well we decided to go the costly route and order a injen intake with the universal bov adapter welded on. now we installed the intake and still have the stock bov cause the new one doesnt comein till monday. he says there is a check engine light on now but wont be at my house till after 230 so what should i be looking for. i have the diognostics tool. not the cheap one but a good one that i can see the accuall readings on everything. im betting its a maf problem but i could be wrong. and the one who commented aboutthe ropes you can go ---- yourself. he just got the car a week ago and this is just the first step in many upgrades to come. im sure when you run your car everyone knows its a turbo jsut becasue of the sound. around here there arent that many turboed cars so he wants it to be known that his ---- is nice. there is the ussual amount of evos and rexs but not any eclipse gst's.

Re: 98 eclipse gst question
 

So, you're recirculating the BOV and still getting a CEL?

Does the setup look like this? If not, try again, lol.

Re: 98 eclipse gst question
 

place duck call in line with intake. :)

Re: 98 eclipse gst question
 

Duck call or coach whistle ftw.

Lol.

Thank you op for just ------- regurgitating what i said about the gm maf and maf translator and then adding onto it like my post didn't make an ounce of sense. It may be a hack mod but it ------- works.

Eprom ecu w/dsm link seems to be the norm in the 2g scene here. A few people are running full stand alone but most are ------- with dsm link/afc's and eproms.

Like i had said earlier, it's hit or miss. If you vent it and it runs like crap, try the gm maf and maf translator. If you vent and all is well, call it done. 2g tsi/gst/gsx are weird like that.

Re: 98 eclipse gst question
 

That's probaly the dumbest thing I've heard in a quite awhile. So a loud BOV is gonna let EVERYONE know his ---- is nice?? No one around here gives a ---- what a car sounds like...as long as that ---- is fast.

Re: 98 eclipse gst question
 

after messing with it a bit and clearing the code just to make sure it wasnt a hickup he still has a cel. it is code p0170. fuel trim malfunction(bank 1) checked the plugs and it seams to be running lean. the plug is almost clean to the point it looks brand new. still havent put the new bov on yet but it seems to be idling funny and missing every once in awhile. we still have it setup just as the diagrame above. at idle it almost sounds like the bov is leaking from around the diaphram when closed so maybe this will clear up tomorrow when we install the new bov. i told him about he gm swap on the maf he kinda doesnt want it to be a hack job so im gonna see what other routes there are but it may just have to be done.

Re: 98 eclipse gst question
 

Alot of ppl run the GM maf on those cars, it's not really a hack. It's probaly one of the better options for that car. Do him a favor and check the condition of his timing belt.

Re: 98 eclipse gst question
 

plus as long as you do it right and make it loook good it wont be a hack it will be a modification

Re: 98 eclipse gst question
 

to the op, dude you're straight ------- retarded.

Re: 98 eclipse gst question
 

GM MAF and translator box FTL! Using a MAF to "tune" your car is a sure route to fail. If you love having a car that's impossible to get dialed in then I suppose the MAFT is an upgrade for you. You have to hack into your wiring harness to install the box. Not to mention you still have your stock ECU on all stock setting that you have to contend with, so trying to "trick" it with a MAF off a ------- Caprice is officially retarded. Yeah they had their moment back in 2002, but now there are way better alternatives. DSMLINK is simply awesome. Yes, it utilizes the stock ECU still, but it can compensate for larger injectors and has a ---- ton of variable that you can mess with. For $500 you can't get any better. The only problem for the OP who is obviously :8; is that he still won't be able to vent his BOV with DSMLINK because it still uses the MAF. The only true way to vent the BOV with no ill effects is to swap over to AEM or a similar standalone, but that's out of the question for these guys. They can't even figure out ridiculously stupid issues, so installing a $1500 standalone and all accompanying sensors is not an option.

The bottom line is that this moron is only concerned about his DSM making a loud woosh. He's not going to do any preventative maintenance and obviously doesn't have the proper knowledge, cash, and intelligence to maintain/upgrade a DSM. We all know that DSM's are very cantankerous, but they are a great platform. Unfortunately they fall into the hands of idiots like this and that furthers their legacy of being unreliable and a pain to work with. In the proper hands a AWD DSM is a street/strip terror and can be very reliable, but in the hands of the unworthy they just fail with the quickness. I estimate 2 months before this guy's DSM is on CL with massive issues and some 18" crome rimzzz.

Re: 98 eclipse gst question
 

if you ------ O0 could read you would see this is just a first step. so ------ what the guy wants his ---- to be loud. who the ---- are you to be the judge of that. to all the people tha twant to be a bunch of cock sucker and are just pissed cause they gotta throw some pos ---- on there car just to make it fast and cause mommy and daddy say theyre to old now and they should have a job and do things for themselves ---- off your just julious cause your ---- is still broke. to the people that accually had a decent cival thing to say thank you for your help. and by the way 98 red cavalier. its a ------ cavalier why are you talkin any kind of ----. thats gotta be the most girlie car i have seen on here.

Re: 98 eclipse gst question
 

once again i said i have never modified a turbo car before. that dosent mean ima ------ idiot. i know the cars potential. i know what can be done i just wanted to know the best route. i would like a honest cival answer thats all. i hate forums where all they do is flame other people. who the ---- cares if you own a crx but wanna swap a 350 sbc and put a procharger on in. to each there own. you seem to be the only one that actually knows what your talkin about so if you could give me a couple links to where i can do my own research.

Re: 98 eclipse gst question
 

Re: 98 eclipse gst question
 

Fair enough. You should learn to use somewhat legible grammar and punctuation too. Big blocks of text are only tolerable if there are paragraphs and they're legible. Not flaming, just letting you know so you can try and not fail so much. The classic DSM site is:

www.vfaq.com (obviously go to the DSM site, not the Prius)

Then there are the forums. A lot of information on them is crap, so double check what you learn. They are DSMsource (aka DSMtrader), DSMtuners (yikes, but some good info if you know what to look for), then RRE has some useful tech stuff, and then the more selective sites like NABR. DSMLINK forums have good info with less bad info, but you have to have bought DSMLINK to register. DSMLINK is actually a great 1st mod because it lets you log and tune which is pretty much invaluable. Every mod you do will go much farther after you've got DSMLINK up and running. It's ------- stupid to go messing with ---- on a car that you have absolutely no way of seeing what's going on. DSMLINK is $500, and there's nothing even close to as good for less than that. Anyway, good luck, and try your hardest not to butcher that poor thing. Some research for you and a nice punch in the nuts for your buddy should do the trick. Fast/Reliable/Cheap, pick 2.

Re: 98 eclipse gst question
 

---- yall

im going back to hondatech.

Re: 98 eclipse gst question
 

After so much useful information posted in this thread, why in the hell would he listen to you.

MAF FTL, even if it is 'only' slightly rich between shifts.

Re: 98 eclipse gst question
 

Yeah that's great advice numbnuts. DSM's use a MAF. The ECU interprets the signal from said MAF. Since the BOV lets too much air in when the throttle plate is open; you get issues like stuttering, stalling, backfiring and low idle. Not to mention your mixture goes all wacky which throws your ECU for a loop so to speak. This is an OBDII car, so it really does try and "learn." Once it's ran with the BOV vented for awhile; it'll never go back to being normal again even if you recirculate the BOV. I guess since you're like a raccoon and are atracted to flashy things; doing something this stupid would be right up your alley. Since the guy who owns this car wants nothing else but to have his BOV heard; IB he does vent it on the stock MAF. That would make him as much a O0 as you. Damn African Americans :3




There is one solution to this "problem" though. Since ricers always want to take the easy route; here it is. Buy a dual port BOV. It lets you recirculate the lion's share of air back to the intake tract, but also lets you vent some to the atmosphere at the same time. It's a total band-aid fix as MAF equipped cars fail by nature, but it's better than venting 100% of the air. Just recirculate the fucker and get a hard intake pipe and hard IC piping; it'll be plenty loud at highish boost levels.

Re: 98 eclipse gst question
 

k we put the new bov on and had it vented into the atomosphere. it ran great. what do you know. it turns out the stuttering and stuff was cause the old stock plastic bov had a huge leak in it. it was where the halves connected. so after we got it all figured out. it doesnt sound half bad. it isnt an insane loud bov it is acually quite ompared to some. now. what would yuo do to make this car haul ass. besides the usuall intake exhuast and bigger turbo. what is a good program to tune with. what about the stand alones you talk about. the car isnt gonna be a daily dragged car more or less daily driven. with a lil power to booot. he wants to be able to beat my chevy fullsize pickup but it aint happenin yet so he is lookin for more power

Re: 98 eclipse gst question
 

sorry didnt read the thread above about dsmlink. i will look into that. it sounds fair enough. and by far the object isnt to butcher the thing. this is a car that he has wanted since it came out. he loves the body style and the fact that he found a turboed one for so cheap with so little miles is even better to him. he paid 4500 for the car it has 65k miles on it and its a 97 so he kinda lucked otu alot. he had a non turboed one for 2 months and got t boned driving home from work one day and after he got a check cut he found this one. he paid 6500 for that one and it had 85k on it. i think the last thing on his mind is to kill it. it is a really nice car inside and out. there are a few minor problems but non that cant be easiely fixxed.

Re: 98 eclipse gst question
 

---- YA'LL I'M GOING BACK TO HONDA TECH

Re: 98 eclipse gst question
 

Ok well if you let any serious DSMers know that you're venting your BOV on the stock MAF; you'll get laughed off the block. It is a very ricer move and gets you no respect. Just laughed at. It is bad for your car. Essentially what you're saying is, "IDC that my car runs slower and has a wacky mixture during idle, low throttle, and shifts because all I care about is that other people notice me." That is what :8 do, so I guess you're a :8. You're already off on the wrong foot. I hate to say it, but the car is doomed. Just you wait.

Re: 98 eclipse gst question
 

everything seems to be in spec though. we pluged the hole for the vent with the suplied plug that is nice and shiny lol. it idles fine. doesnt have any crazy surge or puttering. to me it runs like it did when he bought it. only now it sonds alot better just with the intake. the bov only blows off when he lets off the gas all the way. it is made specifically for this car. it is a turboxs bov. i dont knwo what to tell you other then i checked everything out when he bought the car. even before he bought it i had my scanner with me when he went to look at it. i took down the numbers it was running at and i compaired them today. everything is almost exactly the same except for there is a little more gas flowing now. but that changed when we changed the intake. i dont knwo what else to say other then if your right ill be talkin to you soon about how to do everything the right way. i have already told him abou tthe dsmlink and that is now coming before the exhuast as he doesnt want to blow up the car. so that is the next move. mor ethen likely next week. untill then the car will sit.

Re: 98 eclipse gst question
 

if he wants a reliable and fast car tell him to sell the mitsu and get something else

Re: 98 eclipse gst question
 

FAIL.

Dont touch the ------- car.

This is why you can pick up gst/gsx/tsi's so cheap. People ---- with them and cant quite figure out why they run funny because they vented their bov, put a 3" catback on, and installed an mbc maxing that little t25 out into a ---- hair dryer with 100% stock fueling. Usually these cars are sold as "needs to be tuned" or "needs an maf".

Seriously.

Call buschur racing or road race engineering, hell email shep.... If you dont do what they say, shep will beat you to death with one of his indestructable gearboxes.

Re: 98 eclipse gst question
 

X10

Which is not true because the shep boxes def. are not indestructible. Ive seen them destroyed just as easly as a stocker. PM me for more details on what it is exactly that shep does to his transmissions.
