I have a 97 JDM ITR engine (perfect 270 psi in every cylinder) DC JDM 4-1 header, AEM CAI, Skunk2/RSR N-1 Exhaust, 2.5 in high flow cat. Im guessing maybe 175whp/125tq. It will be tuned with my hondata s200

 

only the dyno can tell

 

i put 180whp and 126lbs on a 00 itr engine

 

was that with bolt ons

 

Well I hit 178+ with just bolt-ons and no tuning on a USDM (lower compression) engine so I guess that you should pull atleast mid 180s with your engine once tuned.

 

thanx for your reply, Im so tempted to swap the cams out but, im leaving the internals alone. I just had a b18c1 block with CTR pistons, full ported and polished head with JUN III and a Sgt JUn III map and I out out 213/139. I sold the engine because my new job requires me to drive 80 miles a day, all stop and go driving, so instead of running that motor into the ground, i sold it to someone who had better use for it.

 

that is just with I/H/E. Not bad with 91 octane pump gas

 

with I/H/E and VAFC I hit 185 whp w/ my JDM ITR motor and I was pushing 240 across all 4

 

depend on which dyno you goto, I would guess between 170-185whp

270psi? damn, that's a lot of pressure for a stock motor, no?

JDM = higher compression. My USDM motor spits out ~237psi. I would expect a JDM motor to be 20-30psi more.

 

man i bet you hit 229 and 169 to the wheels YO

 

perhaps

what's ur bolts on

 

270 psi? Damn dats pretty good. My JDM '00 ITR motor was 210 psi straight across.

 

he'obviously lying..,japnese 97 spec itrs do not lay down 270 compression

Compression numbers vary alot depending on what tool your using. This is why absolute numbers are not that important, what maters is that the numbers don't very across all four cylinders.

FYI: My bolt-ons
- Mugen intake
- Spoon header
- Dynomax Hi-flow cat
- Modified USDM Mugen twinloop (elimintated bottle neck between resonator and cat)
- Comptech fly wheel

 

my 97 jdm itr motor shows 240 across the board.

Should I send you my compression tester, i bet if i used a different one it could be lower. BTW is Japanese, not Japnese, and why would a 97 spec differ from the rest. They are all rated at 11:1 compression. I just posted what I got on my compression tester that all. **** when I had a 12:1 JUN III setup with fully ported and polished head, I was breaking compresion testers, over 300psi in every cylinder.

Umm.. Ok.. Why would he lie? Obviously compression testers vary, but I don't see any reason for him to pull these #s outta his ***.
Nice #s..
