i had a question regarding what kind of horsepower i MIGHT expect for a turboed 9 to 1 comp type r engine, im prolly gonna go with the stock boost setting wich is 7psi, i have the je's pistons and rods. but with the stock computer will it run ok with the level of boost. any help ...

 

Hey man...u should really invest in Hondata S200 with boost option...its well worth the money and your car will gain horsepower from the hondata too. You probably want to run the Hondata too if your gonna do more stuff in the future. Your looking at probably around 260-280....depending....you get that hondata and tune it and you will hit around 270 whp...gl with car man

a type r is a pretty high compression motor so you would have to lower the compression to get the turbo setup. I would say go NA

 

yeah with the right N/A setup i've seen some ITR motors that made 289hp... im planning an LS/Vtec swap with my B18 block and a JDM B18C head...articles that i've read about high hp B motors, i just want to find the highest hp motor out there and copy everything they did...and then see what happens

 

10.6:1 is not too high for turbo... all he would have to was invest in some quality tuning and he would make more power then a GSR or LS. Theres a couple guys on here with stock b18c5s running around 8 psi for a couple years.. tuning is key.

 

Yeah, I run 10.6:1 with Hondata, GReddy turbo kit. 295 WHP at 10 PSI. I do HPDE's too.



Good luck with it.

If you are only running 7Psig boost, there is no reason to run 9:1 pistons.

 

this is the second thread i've seen talking about this... man i hate fouble posts... prolly posted somewhere else too (see the Civic/el thread for more...)

 

thats quite impressive to run 10psi on a stock type r block and still make reliability. Hondata is amazing.

 

i ran 12 psi on my completely stock internal ITR for a long time an had no problems. tuning is key, as posted before. when my car dynoed i hit 270 with 12 PSI on stock internals. all i had done was msd, and minor fuel tuning. with 9:1 compression u should be able to push 14-16psi with correct tuning.
