Is it worth it?
 

I was wondering if it is going to be worth turboing a b18b1 or should i just get the gsr non-turbo. I want to be able to beat a gsr but i don't want my engine to blow. I was wondering if running b18b with turbo and fuel managment and a msd btm at 8-10psi max is reliable. I want it to last a long time. Also with that amount of psi how much hp do you think i could get out of the motor. I was hoping for 240-250 at the flywheel. If you could estimate that would be great. Thanks for all the help.

Re:Is it worth it?
 

turboing anything is always better. you will always get that response on this forum. A non turbo b18c could make some impressive numbers, and be reliable, but if you wanted reliability, buy a factory turbo car. I would turbo your b18b1 and keep it properly tuned and maintained.

Re:Is it worth it?
 

Alot of different factors, but I'm guessing my 15psi will be about 300 at the flywheel. Go turbo. Anyone can spend money on a motor, you get respect for putting your own turbo together.

Re:Is it worth it?
 

what i meant to say was if you want high horseys and reliability buy a factory turbo car. it's hard to make small engines n/a highoutput hence: no replacment for dicplacement unless you substitute displacement for boost.

Re:Is it worth it?
 

i don't want to get a block guard but I will spend the money on engine management and fuel management. So will the turboed engine last if i take care of it, like change oil every 3,000 miles and don't cut to many corners on the cost? I need this car to last if i am going to spend 2g's on the motor and then 2 more g's on the turbo. Maybe you could tell me how long your cars have lasted. Also i Don't want to go stock car turbo because it is too expensive.

Re:Is it worth it?
 

it could last as long as you want it to. just watch your a/f ratios. and high amounts of boost makes engines not last as long. 6-8 psi is what most factory turbo'd cars come with.

Re:Is it worth it?
 

Ok so 6-8psi and watch air fuel. How much hp do you think i could get at that amount? Will i get at least 210 at the wheels?

Re:Is it worth it?
 

b18b1 right?? i would say probably 190 or so. but with a zdyne you get lots of torque.

Re:Is it worth it?
 

why do you guys like the zydyne so much. Do you recomend any other units?

Re:Is it worth it?
 

i would not classify a turbo'ed honda as "lasting a long time" car.

itll either blowup because of user error, or u will do something else with your car.

1psi = 10hp tuned well. 5-7 not.

Re:Is it worth it?
 

i would listen to him before me

Re:Is it worth it?
 

Why don't you think that it will last long? And what is user error?

Re:Is it worth it?
 

Listen to Who?

Re:Is it worth it?
 

honda' bearings; main's and oil passages and the way the block isn't decked are all factors on how the turbo'd motors will hold up from time and boost. User error means imroper tuning or too high boost numbers on stock internals, or just any error caused by the driver.

Re:Is it worth it?
 

lusten to the administrator of a turbo site. he's got a lot of know how I'm sure. (shortyz)

Re:Is it worth it?
 

once you start to boost, you will notice yourself saying "oh it's only 2 more pounds...."

Re:Is it worth it?
 

Ok what is if i changed my plans and got a Sohc vtec motor and boosted that to 6-8psi would that beat a gsr with a lot of mods? I don't think i would be too worried about blowing one of those? Also can you use a zydyne on any ecu. For example if i did get the Sohc vtec motor and decided to upgrade to b18b1 later could i use the same zydyne or will i have to get a new one?

Re:Is it worth it?
 

A b18 can get 210 with 6-8 psi...Its all a matter of tuning.

Re:Is it worth it?
 

What about the SOHC vtec do you think it can beat a fairly modified gsr integra? Running 6-10psi?

Re:Is it worth it?
 

non factory boosted cars, that you make custom setups for will not last forever. the engines aren't made for the heat that a turbocharger makes.

most people don't have problems but, oil/water temps go up, valves and pistons are exposed to high heat. trannies axels clutches ext don't last long.

i'd say your biggest problem will be drivetrain problems, like trannies and definatly clutches.

if you want to make your car faster and have it last forever spend the money on a supercharger.

Re:Is it worth it?
 

It will hold up fine.
You said you was gonna spend 2 g's on the engine? and an extra 2 g's for the turbo setup?
Well if the 2 g's for the engine is for forged rod's and forged FI pistons/rings and new bearings and maybe resleeved or posted it will hold up pretty long if you tune the fuel management right, just don't lean out. go with a good management system ... with that budget you can get the zydyne.
With forged internals you will reach your goal...even surpass it.
Maintannce is the key...and if you have money left..i would get e more efficient radiator to cool things down.

Re:Is it worth it?
 

With a supposed budget of 4K, there's no reason why you can't build a serious, reliable, turbo B18B.

Re:Is it worth it?
 

2gs was just for the engine it self?

Re:Is it worth it?
 

It really depends on how you drive the car -> as already mentioned a non-boosted factory car was not meant to be boosted and won't last as long as an engine forged to handle it. Thats just a simple fact, but Hondas can withstand the rising engine temperatures very well... it just depends on how you're maintaining the engine... mine lasted about 8,000 miles before I flattened a bearing but I wasn't paying attention to detonation and kept putting it off to fix it. Well its stupid things like this that will cause your motor to go out!

Just keep in mind that a turbo produces more heat, and more pressure than the factory intake does. There are ways to reduce the heat, ie, intercooled or water injection. But the pressure is still a problem, but if you keep your engine timing retarded you should be okay to get around the pressure without causing serious damage.

Just keep your ear out for pinging/knocking, and an eye on the thermostat :)

Re:Is it worth it?
 

Besides hp will the sohc vtec be as good or better than the b18b to boost?

Re:Is it worth it?
 

b18 rods are a little beefier than sohc rods. so a b18 will handle boost a little better than a sohc. A sohc vtec isnt real vtec however. It is an imposed vtec or mechanical cam retard rather than dohc vtec. A sohc vtec motor is no more than a sohc vtec motor in exception to a little boost of cam retard at 5500 rpm. Ideally you would rather a b18b over a sohc of any kid for reasons of being able to adjust intake valves seperate from exhaust (overlap). This gives you basically more tunability. But I say if your car has a sohc, then turbo the **** out of it, if it blows then it gives you a reason to put a b18 in it. If you already have a b18 then turbo it anyway!!!!

Re:Is it worth it?
 

these are my choices as to what engine i want to get, a B18b or a SOHC vtec and boost. I have never boosted before so i was thinking about boosting a Sohc vtec and then see how that goes and then maybe later swap in a B18b and boost that. If i bye a zydyne unit will it work with the b18b and the Sohc Vtec? Also i Didn't Know That The Sohc Vtec Was Not True Vtec. I can get a Sohc Vtec off of hmotorsonline for 500 dollars.

Re:Is it worth it?
 

my friend once ran a 90 dx ecu to run his b18c5. It didn't run it very well and his vtec didn't turn on untill he got a type r ecu but it ran. If you bought a zdyne for a obd1 sohc vtec motor I don't see why it couldn't run a obd1 dohc non vtec b18b as well since you can custom tune all your fuel maps, and spark curves i don't see any problem but I would ask zdyne anyway. There are other options other than zdyne. You need to know which engine exactly you are going to be tuning. Just remember the higher the obd number the less and less anybody will want to make a standalone management system for it. I am cursed with obd2 and I have found efi systems(efisystems.com) they make obd2 stuff. But anyway, as long as your in the same obd range I don't see why you couldn't change motors and retain the same managment..

Re:Is it worth it?
 

What do you think about the Sohc vs B18b should i start with the Sohc because it is cheap and i can always get a new one? AND THANKS FOR THE INFO!!!!!

Re:Is it worth it?
 

hey info is what this site is made of.. I would start with a sohc because there are so many and can be had for cheap. Ionce bought a 91 crx si engine for 25 bucks.

Re:Is it worth it?
 

thanks man. Can you recommend a turbo for the sohc vtec? I have been doing a ton of research on b18b and then i decided to change my mind. Also how much psi can you run safely on one of the SOHC motors? Thanks for all the help

Re:Is it worth it?
 

i have a d16y8 (98 ex) sohc vtec. I am peicing my custom turbo project now, and I have a gen2 t-25 eclipse turbo. This turbo is incredibly fast spooling but doesn't pull that hard at the top. the first gen eclipse turbo(14b or g i think) spools slightly slower but pulls pretty hard at the top. I would recomend either of these turbos for a sohc which ever is easiest to get a hold of. I bought mine for 75 bucks. a sohc motor if built right could probably run upt to 20 psi maybe even more. It depends on your compression ratio, rod strngth and tuning(engine management)
you could probably run more than 20 psi is just costs more cheddar

Re:Is it worth it?
 

Wow that sounds like a lot. But how much could a stock sohc push in psi wise?

Re:Is it worth it?
 

5-6 crappy managment (rrr)
8-9 zdyne
psi ofcouse

Re:Is it worth it?
 

ok thanks. That works for me

Re:Is it worth it?
 

that turned into a pretty long page!!!! any more questions just ask, I am new to this too but I love to research so ask away.

Re:Is it worth it?
 

umm if you totally build the engine .. ie pistons, rings, rods, sleeves, balanced, honed, bored, decked, tanked etc it will prob last longer but will cost you quite a bit. $2200++ (and thats with hook ups at machine shops) i'm just gonna go stock zc with n20 (200 wheel hp) and turbo later so what if it blows up .. i can get an si motor cheap until i build a stronger zc to put in.

Re:Is it worth it?
 

What do you mean a SOHC vtec isn't real vtec? It has the high rpm cam profile same as the B series (Well, the D16Z6 does) and neither has variable cam phasing. In theory, the Vtec systems on them are identical, with the exception of variable valve timing and lift are only on the intake side of the SOHC, while DOHC have variable intake and exhaust.

Re:Is it worth it?
 

So It is true vtec. I have a question is vtec just as loud in the sohc as it is in the dohc when it kicks in? My friend has a gsr and i just love when the vtec kicks in it is really loud and you can feel it throw you in your seat.

Re:Is it worth it?
 

DANG!! Y'all people talk too much. lol :P

You can keep it reliable... A B series engine is going to be more reliable than a D series, and a D series turbo can hold up for a LONG time with 7-8psi on good fuel management. Just take care of the car. Take CARe of the CAR... The CAR needs some CARe. I have a purple mongoose in my pants.
