I re-did the compression test today on my 00 JDM ITR engine (last time I forgot about WOT)..

Here is what I got:

186, 190, 188, 191

I know my compression is fine, but what I'm wondering is if other people are getting the same compression numbers on a STOCK JDM ITR engine??

Someone in my other thread said his was around 220+, but I don't see how I could be that far off. This motor is in awesome shape and burns no oil.

 

was the motor warm?
dou you have enough oil in the motor?
how many cranks did you let it run...or did they all die at the numbers you stated?

my 00 itr motor puts 270 accross the board, all within 5 cranks.
stock block
just milled head, and a 1 layer headgasket.

i beat the crap outta my motor, but it seems to get better with age.

 

yah motor was warm. I even cranked it about 8 times to be sure..

Should I do a leakdown test?

 

Also... I bet it might be a faulty gauge....

can someone give me some input on this? My engine feels fine when driving, it's powerfull, but this seems too low.

I should be above ATLEAST 200... I know it..

i had 210-220 on my old LS/VTEC stork Ls piston stock GSR head,
Couple days ago i did test on my rebuilded LS/VTEC , i got 250-260 without WOT.
with CTR piston .25 over, stock GSR head.

 

with ctr pistons in my setup (listed below, im well over 300 psi in every cylinder

 

Anyone else have input?

 

Try out a new gauge...I have one if you are interested...otherwise tell LWTC to get a new one

 

Yah, I'll do that. My engine runs too strong for me to believe this gauge. It loooked pretty beat.. I'll try another one. If I get the same results, then I'll dish out the leak-down test.

 

good post

 

Geese my gsr stock motor put down 210 across the board and i doged the **** out of it.

 

I dod on my 99 JDM itr motor its 215 accorss 4.
is that good condition.
