just purchased a 94 jdm gsr b18c swap in a 94 civic coupe and did a compression test, cold temp. results as follow. are these results normal or is it time for a rebuild. never did a leakdown test cuz i dont have the tools for that. ive search already but found no answer. reason i ask cuz, i noticed a lack of power. mods are cai/header/exhaust/msd blaster coil. at this point car runs very rich and did a baseline dyno only to find with 150 whp 114 trq. can any one chime in those who got stock gsr with bolt on mods. im kinda concerned performance wise tia for all reply


cylinder 1) 190
2) 190
3) 185
4) 185

 

compression seems about right. get the a/f tuned properly.

 

thast the hp GSR motors make with all the bolt ons. Its avg. I made 160 with intake,header,exhaust, vafc2 and fpr. Tuned

those are some good comp #'s here is the link to my bolt-ons gsr that you can compare. If you stated the car is running very rich, then it will actually hurt the performance since injecting excessive fuel will have less to chance atomized properly. Result, loss in power. Someone said earlier, get the a/f tune out. Btw, you should get ur car to a shop and do the leak-down test, compression didn't tell you whole lot about the condition or the car

actually those numbers suck ***. what kinda mileage does your motor have? anything under 200 isnt really healthy for a gsr. mine cranked out 230 across the board before i rebuilt it. and cranks 240 now with the itr pistons in it

 

as stated in my first post , those result were done on cold temp not at operating temp. i know if it was tested at operating temp i would get higher results. as far as mileage, i would have no clue what mileage its currently on since i bought them from password jdm as a front clip.

 

maybe since your unning rich your burning valves. your rings could possibly be worn

 

i never knew that operating temp made a difference. everytime i tested my cylinder compression the motor was cold

 

bump for more info

 

helms says from like 180 to 230 is good

mine came out around 185 to 190...

its more the #s being closer to each rather than how high they are

of course if a # is way out of range then you know something is up
