SOHC Turbo injector question.....
 

hey i have a project 95 z6 del sol which as i understand is obd1 (please correct me if my nub a$$ is wrong)....anyway if that's correct i should have saturated type injectors so ive been looking at rc's i don't wanna go dsm (i hate cutting wires) .... to support 300-330 whp easily i should be looking at 550's right?.... stock flows like what barely 220cc?

*also are there any real reasons not to go with the biggest Fu@#in injectors they have? ... i plan on running a standalone so im assuming you would be able to control output ? or is there something im missing ? this fuel ---- annoys me...

feel free to post your setup and whp they support (and wether or not your satisfied )...........................BALLZ

Have you already started to build your motor? What pistons, rods, etc are you using? I understand you don't want to cut wires..... but with DSM's... you really aren't cutting a ton of wires and it can be done very clean for easy connect, and disconnect. My neighbor did a really nice quick connect system on his resistor box so it was clean and easy to take out/in. You may consider it. 450cc's should hold close to 300hp. I have a Z6 right now in my 94 ex coupe and I just started cleaning up my new(used) Z6 block this evening. Currently I'm running a T25 @ 8psi everyday, but my new build is going to be 75.5mm Vitaras and FJ custom length I-beam rods. My power goals with that are 250 -300 as I need to keep it cool for daily driving and somewhat economic. My current set up gets 34 mpg everyday.

have you checked out the bosch injectors from Injector Dynamics? i have no real experience with them since they are kinda new but from what i have read on there site they seem ok.

They come in 750cc or 1000cc which is good if you are planning to go bigger in the future and they also sell injector plug adapters to make it plug and play. ( no resistor bock or wiring)

gimmie a minute and i'll find a link.

here you go.

arok,
sounds like we have really similar goals , the sol is my DD so i dont want anything too crazy and it definetly has to be streetable, FL doesnt have inspections though +1, anyway yeah the bottom end is running cp pistons and pauter rods, head is a fresh rebuild to stock specs. (hey are you using a cometic h.gasket?) turbine is a turbonetics t3/t4 48 ar. i have been looking at some finished dsm installs and i do see that they can be done right..... i dunno i guess im just lazy or to much of a ----- to hunt down what i need ....... anyway let me know how your build turns out you'll probably finish up before me ............

oh and nice post louie..... at 500 bones those are pretty $baller$ so i might stay with the rc's correct if im wrong but saturated rc's would also require little to no modification of the factory fuel system (not including a new fuel pump of course)

stock injectors are 240cc. the dsm 450's seems to support around 300whp. they can be cleanly installed where it looks completely stock, i did it on my own car back when i had them.

you can get RC injectors that require no modification. just bolt in.

a stand alone is retarded in a honda. chip your ecu and run ectune. you wont find anything much better for a honda. i just made over 500whp with my vitara block on ectune with 31psi and a 130 shot. its great.

there really isnt anything bad about over sizing your injectors within reason. a good tuner can make pretty much any injector idle. you should keep your goals in mind though. if you plan to make 500whp you dont need 1k's. i run 660's on my DD civic at 310whp daily. thats bigger than needed, but it runs great and gets 30mpg's.

where in FL are you? i live in St. Augustine, but my shop is in Jacksonville.

edge,
DSM injector set ups are soooo easy. It takes just as much time to find DSM's than it does to find any other. I can even make it easier for you... My buddy has a set of 450's with resistor box he wants to sell. All you need to do to plop them in your rail is to slightly modify the bottom injector seals or buy a set already modified for like $9 on ebay. Biggity bang! done deal dude. If I recall, you can even find a set by step write up with pics somewhere on this site. I recall reading it a million times a while ago. I pretty much wanted to keep the rebuild simple on my Z6 so I went to FJ's website and gonna pic up the Z6 race rebuild kit. FJ makes it so easy and uses all quality parts.

Sorry to thread jack a bit. What size vitaras you using? I need DD with good MPGs and it sound like you are right at my goals. What turbo you using and clutch? I have access to a couple 16g and 18g turbos and was considering using one of those on my build. I really want a turbonetics cause they are purrrdy.... well, they are good turds.

650 or 550 and youll be good for dd 300whp

75mm vitaras, LSD 385ftlb clutch, and one of my t3/to4e turbos.

I don't really consider a 75mm vitara setup a good DD car. It rattles almost all the time and smokes some when it's cold. There is also a ---- ton of blowby. If you want to DD with vitaras, I would get the 75.5mm pistons and have the block bored to fit them. You aren't going to break any records like I did with thinner sleeves, but you will be happier about driving the car.

I built my block with the sole purpose of braking the vitara record and making over 500whp. That's why I used the 75mm pistons. My turbo setup was made with daily use in mind though. Things came up and halfway through the build I had to change directions and slap the car together for daily use.

Yeah, I was going to go with the 75.5mm cause I did not want the piston slap. When you say "one of your own" turbos, what kind is it? Are they any good and hows the reliability? I was considering the LSD clutch but was not sure on the ftlb's. Thanks, that helps. I am not married to one specific turbo and since the motor will be new, I would not mind a new turbo. Got something good for budget and reliability? I know that sentence makes virtually no sense.

well, my turbos are chinese. they are better than the typical ebay stuff, but still chinese. i have recently realized that they need to be kept at 10psi and under. the thrust plate in them just cant handle any more. i have tons of them running around with stock block setups and no problems, but i have been through 2 myself running 15psi daily. i usually get 3-4 months out of them. i even have one with over 30k miles on it running 8 psi the whole time.

Wow... pretty impressive for cheapies. I was thinking of using a 16g or 18g. I've always had good luck with mitsu turds. I'm sure I can crank one of thems up to 15-17psi and reach my power goals. I still want quick spool up.

yea, they are more reliable than the cars they come from. lol. you should be able to hit your goals with a big 16g or bigger

Werd! My tuner was pretty confident in the 16g when I ran my goals by him. They tune mitsu's all day long. I want to throw some power down when a V8 rolls up so they kiss my ass when they get smoked by fried rice!!! "That's pork fried rice you plick!!!"

31psi on vitara's .....you say.... 500whp... dude i am IMPRESSED... i'm located in lake mary florida. i see you mentioned "your shop" exactly what services do you offer? do you personally support ectune? because if so the 2 hour drive would be worth the payoff, your numbers speak for themselves. Oh and the only reason i was talking standalone is because the guys at titan motorsports are rich bastards. Who only work on serious vehicles (mostly supras) so i better come correct for them to work on my econo whip. My problem is they are the only one's relatively close besides CFT (and i've heard bad things about them)

*And arok you've almost got me sold.... but im still on the fence..... ill search the writeups..... how much for you buddys' equipment?

i am a performance shop, the only thing is i dont have a dyno yet. its in the works, but i really have no idea when it will happen. if you want a good dyno tune, and you are willing to drive, you need to talk to Tom Sewell. he is an authorized ectune dealer and he actually did the tuning on my car to take the vitara record for the short time i had it.

his name on here is sewell94 or you can find contact info on the ectune tuners list eCtune.com > Authorized Tuners

i am not an authorized tuner for it, but i can street tune with it if you buy it. i have used pretty much all software for hondas.

also, i noticed you saw the 31psi, but did you see the 130shot on top of that? we put that block through hell that night and it took it like a champ. lol

so as far as the financials are concerned, what would be a respectable ballpark figure for a complete ectune setup including the neccessary electronics ( by this guy you recommend) and ill search for some info but is there anywhere i can find a good writeup/info on their software?

It depends on how you go a out it. If only he tunes it, he charges $350 for a dyno tune and that covers the ectune cost or he charges $250 for a street tune and that includes the ectune. You will need a chipped ecu for him to tune it. I know he chips ecu's but I have no idea what he charges for that.

If you want me to tune it or do anything yourself with it, the software is $150 and then you will need a moates ostrich ($175) or the moates demon ($250)

I have a 4G63t in my 92 Colt with Evo8 pistons, 1G big rods, Evo3 cams and balance shafts eliminated and I plan on running a T04E 60-1 and an external 40mm wastegate. I want to put a Walbro 255HP and a set of 1000cc Siemens injectors in it to handle 25-30 psi.
Anyway, a set of 450's could get you 300hp easily. I ran those in my Talon on an EvoIII Big 16G and it ran well up to 17 psi which got me 300 HP. You should call Chris at Xenocron and order a ZIF socket and ask him to burn you a custom chip. Give him your current setup specs and what you plan to run for injectors and he can make it so you can run whatever size injectors you plan to get and still idle properly. My 92 Integra ran a B18A1 with a Dodge Daytona T3 on it at 12 lbs on a stock block and I made 256 whp on a Walbro 255 and 390cc injectors from an automatic DSM. He burnt me a chip for my PR4 ECU and I socketed it myself and the car ran like a dream. Pulled HARD.

BTW, Sorry EvansPerformance, I'm not trying to undercut you. I'm sure you know your stuff too. I just have a good history with Xenocron so I'm kind of partial.

i have a 3 month goal on the time frame of this build, you should p.m. me the address of your shop, also see if you can get this guys contact info or let him know that i have a virgin p28 out of a 95 del sol (d16z6) if he can do the chip great if he wants me to get it chipped thats fine too..... Looks like i found a new home for my tuning solutions. Fu@%ing hate driving 95 though, too many tourists.......

Too bad you don't live out in Washington. I got my P28 chipped and street tuned on CromePro for $280 by English Racing. They will be tuning my new set up as well, but i will dyno it this time. Last time the dyno was down and I did not want to wait. LOL

I'll ask my buddy how much he wants for the 450's. I'll PM you when I get the info.

I'm not too concerned. Chris is a good friend of mine and he is an awesome tuner. Hell, I have a few prototype parts I am making that will end up on his drag car soon and hopefully for sale on his site. I even told the guy of another shop he could go to for a tune. The problem with getting a chip from chris is that it won't be tuned for the car. He will even tell you that it's not meant to be driven hard. Basemaps are to get you to a tuner, not go street racing on.

All of the info you need for Tom is in that link I posted. He is a badass tuner and you will be happy when you leave his shop. I do all of my own street tuning, but when I need a car on a dyno, I make the 3 hour drive to see Tom.

If you want a good, cheap street tune I can PM you my info, but if you want a dyno tune, I recommend Tom over pretty much anyone, at the very least in FL if not farther.

Chris helped me when I turboed my D15B JDM Civic. He sent me the P28 ZIF socket and basemap chip for less than $50. I bought the DIY kit. All I had to do was buy a solder sucker and a cheap solder gun. I knew about the basemap thing, I talked to him on the phone and he told me that. He DID however send me a basemap chip with stock P28 fuel and timing maps modified for my 450cc injectors. My car idled perfectly even though I never got it tuned.

ok so i follow that tom kicks a$$ for an affordable dyno tune ...but i still need to know will he be able to offer chipping services /a basemap to crawl my ass to jax? or do i need to supply everything for him to be "ready to roll"......thanks for all your help bro....

tom can chip it for you. he has all of the stuff. i get my chipping parts from him when i need it fast.

4G63Sleeper, i know Chris is good, and,im not saying a basemap cant run well. im just saying i wouldnt push the car on a basemap, thats all. i sell basemap chips all the time. i havent gotten one complaint about how the car runs.

No no bro, please don't take me the wrong way. I was simply agreeing with you. Maybe I didn't word it correctly. $400 for a dyno tune is pretty cheap BTW.

I must have taken you the wrong way. It's cool
