I´m in the progress of bulding my engine and there are only a few parts I have to buy so I asked myself how much power will this setup put down. I don´t have the money right now for sleeving the block. I´ve tried to compare my setup with otheres but I cannot find a GT4088R dyno graph with less than 18PSI. Here´s my setup:

B18C6 engine
eagle rods
9:1 cp pistons
maxworx turbo cams
full ferrea cylinder head internals (no headwork)
Full race divided T4 top mount manifold
2x 44er tial wastegates
Edelbrock victorx manifold
750cc injectors
full race 3"to 4" downpipe
3" vibrant cat back exhaust

What do you guys think is a save and realistic power this engine is able to put down? Its more a street car than a track car.

well you need to tell us how much boost you plan on running...

also, its very difficult to tell you becauseof so many other variables. The tuner could tune conservatively, or no, and that comes into play a lot.

Just go get it dyno tuned!


also, is the vibrant exhaust the TPV system? all through them? the stainless steel one?

I want a sound clip when you get it up and running! I want that exhaust, but I wanna hear it first!3

I´m not sure about the boost. My tuner told me I don´t want to boost more than 14PSI on a unsleeved block. I´ve seen many setups here on HT with more than 14PSI of boost on a stock block so I´m a bit confused. Oh and he tunes the car with crome I know it´s not the best.. I´ll go with hondata AEM or somthing like that when the block is sleeved and the headwork is done etc... But now I´m on low budget so there isn´t much money.

Do you have a boost gauge?
so it's already been tuned?

With that big of a turbo, you may be pushing an amount of power that people would consider dangerous with stock sleeves, but I really have no idea.

500 is about much as i would want on stockl sleeves.. ever...

I'm in the same boat. Do you guys think 400-415 is ok on stock sleeves?

THEDirtyDseriesWOOT

people make 400-480 ish on stock sleeve d-series all the time 450whp is just fine on a b ..

Thanks, man.

pushing the psi wont be the issue. your 40r @ 14psi will be wayyyy more than say a t3 60-1 @ 14 psi. and i would agree with the other guys saying nothing over 400 on stock sleeves. just as long as your "AWARE" that it could go at any point.. just depends on your luck of the draw. i understand where youre coming from, from a budget build, as i am in the same boat. thats y im taking so long for my finished build, i dont wanna take any shortcuts this time, like i did the first time... which resulted in disaster. but anyway, your setup is nice. keep us posted on the dynos, im in for some numbers.

As my avatar says, I'm a noob, but how does the sleeve break? What does putting in new sleeves do? I only want 401 whp!

it make them basically unbreakable.. you can run as much boost as your head studs will hold.. upwards into the 1200hp marks.. ull be fine on stock sleeve with that

Well let's just put it this way.

The sleeves were built for slightly over stock power. However, people have been regularly seeing 450-500whp on stock sleeves due to good tuning.

One thing is for certain, just a tiny bit of detonation at those power levels will kill stock sleeves quick.

So it will be relatively safe at 400 whp on stock sleeves. I don't want to get a tank of bad gas one day and blow my motor. Would it be safer to get a tune on 89 octane instead of 91 just in case? If I run 91 or better I'll still be OK right?

That is a bigass turbo to only want 400whp... What made you decide to go with something so large? Seems like you could have met your goals and spooled the turbo a lot quicker with a gt2871r or gt3071r and saved some cash.

You said it is more of a street car then track which is why the gt40 seems like overkill to me. To each their own i guess.

I choose this turbo because I definitively will sleeve my block in the future and and than the car will see the track alot more. I want to have a good turbosetup which supports 600-700HP. I don´t want to go with a smaller turbo and after a year or so I have to buy the bigger one. I´ll drive the car more on the highways than in the city so I want some realy good top end power ;-) Spool time isn´t that much important in my case. I´ve seen some guys here on HT which reach full boost at ~5500rpm on a 2L GSR and thats ok for my taste

sp00led

Fair enough.

I use a gt3076r. Here is an example of spool on it which is why I thought a GT40 would be much more unfriendly for a street car.

I haven't researched it but I figured a GT40 would spool more like right over 6k.

hovic

because of the twin scroll turbine of the GT40R and my divided full race top mount manifold the spool is/should be very good. I´ve had the GT3076R before but I decided to sell it and go with the GT40R because the GT3076R won´t reach my gools. I´ve never used the 30R and it also had the divided T3 housing which sould be too small what I´ve heard..
