Here's the setup, Stock Itr motor, drag 3 kit, stock compression, Rc 440's, upgraded radiator to fluidyne, and hondata s200w/boost.

Just got my car tunned at importbuilders, I was hoping for more power but i also wanted a safely tunned street driven car. My goal was 7-8 lbs with 240-250 whp. but i guess my motor was running to hot and didn't want to risk detonation. I dynoed with 4psi and 5psi the question is do you guy's think I could raise it more?? Jeff said he didn't really want to to keep that good a/f ratio. But on with it here it is:

keep in mind this is at 4psi and 5psi on pump shitty 91 octane in cali. and yeah it was hot that day.


and pics of the my setup.


if heat was the case in this matter, my future mods are vented carbon fiber hood, changing themostat, higher boiling temp coolant (suggestion needed), and a cold air mod for the intank pipe.

Thanks.

one last thing, in the pic the fmu is now gone, and is it necessary to keep the fuel pump??

 

I wouldn't chance it with stock pistons...my stock piston rings shattered at 0.6 bar (8psi roughly)

get some forged internals first...

 

with your compression... i wouldnt suggest raising boost. If you plan on building a motor... the best thing is to sell your whole swap... and build a gsr bottom end. You could get good money with the type r bottom. By the way.. you are running an upgraded fuel pump right?

 

pull up your skirt man . ive been pushing 8-9 psi daily and 11 psi pretty often too . my car runs like a **** . i still get 250 compression straight across the board.
trust me it can take more .
the graphs do look really good though. mine gets a hell of a dip when vtec kicks in . we gotta tune that out.

No need to swap motors, the Type R motor does extremely well with turbo (if tuned right.) I am making 290whp+@11-12psi...only reason that I am not making more is due to exhaust restrictions...I should be making more than 300whp at the same psi. I also need larger injectors so I can turn the boost up a bit more...My tuner says 350whp easily if I put in about $200-$300 more.

Bottom-line...if you want to see what a type R can do under pressure, you have to build it first!

 

i agree. but if you plan on resleeving.. i would just pick up a gsr bottom..... get some money for that type r bottom. thats all. its all the same after its all built and resleeved.. with the exception of the crank... etc.

 

why ? if he alerady has the motor why spend more money to get another one ?

 

I personally think a 250WHP is pretty dam fast for a street car. I would leave it alone and be happy till you have $$$ to build the engine.

the reason is because of down time etc...A gsr block is cheaper than a type r block.

 

why did you sepnt money on an bigger radiator. I had absolutely no troubles with colder thermo and A/C too. Turn up the boost to 6-7lbs, you should be fine and you have the fuel capacity to do it. Dont worry on the stock sleeves, with proper tuning it is not a problem

 

good looking engine bay. any guesses on y you were running hot?

 

You should be making more power in my opinion. You should also be able to turn up the boost.

How does the part throttle feel?

Not sure what you mean by "Jeff said he didn't really want to to keep that good a/f ratio"

Jeff can't tune for ****

Keep in mind this is only at 5psi. 225 whp at 5 psi is really good

 

i dont think those number are bad at all....considering you are on 91 octance...a hot day..and only 4-5psi which isnt much even with that turbo.

nice radiator hoses too...samco

 

If you're looking for better cooling, this is supposed to be really good. It's kinda spendy at $25 a gallon, but I don't think you really ever have to change it.

i dont have overheating probs with mine , stock radiator which is beat to hell . stock thrmo , bullshit coolant , no probs here. how many runs did you do ? he might have meant it was heat soaked from all the runs

 

I think with the hondata he should be able to boost more (7-8psi) safely and should be putting down more then 225whp @ 5psi. I'm running a VAFC and putting down 254 with stock comperssion, stock injectors, stock motor.....but then again Tony tuned my car......

 

I'm running a similar kit on stock B18C6 on AFC hack @ 8-10psi untuned. I only have 3" rear muffler and de-catted for the exhaust but soon to be 3" downpipe back. On a good cool day I get a little over 300hp. Waiting for standalone and forged internals. Been boosting for 3-4 months so far so good..

The car sputters sometimes, the funny thing is when street tunning the car felt fine. but after i got home that night it sputter alittle at part throttle, (driving regularly), and jeff said i could really get any better a/f ratio without sacrificing timming, he said he could be making more power but the graph would look as smooth. But he also said my motor was one of the healthiest B18c5 motors he ever tunned. I know I can hit 240-250's with 7-8 Psi and get a good a/f ratio.

And my car is not having problems overheating its just running to hot, and yeah heat soaking on the dyno, but i know that happens after pulls. I just want her running cooler and getting cooler intank temps.

Also at part throttle it feels like fuel cut off (sputtering), and also at WOT i hear rattling, its audiable when windows are up, i think its detonation but not sure, because i really don't know how that really is suppose to sound, any suggestions on it?

Lastly, Planning to get rid of my high-flow carsound cat, its 3inch, but going to get a test pipe.

Thanks for all you info guys.

Oh, yeah, totally tunning time on the dyno was about 1hr 30min.

good numbers for only 4-5psi. I say you should crank up the boost now that you upgraded your injectors and hondata on your side. This should roughly take you around the 300whp range safely even on that shitty 91. My buddy's ITR made it to 299whp flat on a APEXi power FC with a similiar setup. To my preference, id love to have that high hp output but we live in so cali so im not sure about the physics of driving a boosted car in 104 degrees.

 

Been boosting my ITR stock motor at 10psi for 24,000 miles without a single problem.
Turn the boost up IF YOU WANT TO, not because everyone says to. Dont let her ping though. If I were you, I would invest in a J&S safeguard.

By the way, those are great numbers for 5psi.

Thanks, I want 240-250 on 7-8 psi Dammit! , i'll try to get my car running smoother...gonna go back for retunning. and more cooling mods.

by the way how does detonation sound??? or pinging??

never got a clear cut answer on that.

 

 

i like turbo anything but cars that were meant to rev all motor should stay all motor IMO...ur power at 5 psi is very impressive but why didnt u want to spend the money for a fully built head with the s200...its no where near 225whp but u can get 200whp from ur motor fairly easily and be more reliable with the money u had to spend...
