ok the car can run all day and when i turn it off fr 20 min, and let heat saturate it, then go drive again, the first 30 sec its got NO power. and its also lacking about 30HP the rest of the time. i checked comporession and i got 200-225 all across and the plugs are light grey on the tips. i was thinking the cat might be the problem, but i checked temp before and after the cat and theres 100 degree difference. do u think the cat is clogged anyqways? what else do u think could cause this problem ? BTW its a b16

 

the cat can be clogged the only way to fix it is gut that bitch. that is proolly the problem

 

yeah thats what i think too, but i was thinking of taking ot off first and seeing how the motor drives.. no cat dirving around will be fun for about 30 secuteil i get pulled over by a cop heehe

 

Yeah, I ran straight header once... Be prepared to take about 40 Tylenol with you...you WILL get a headache after about 14.538 seconds of driving it.

mine was in 12.7

 

check it out, i just took temps and i got 230 before the cat and 200 after the cat.. u think thats the prob??

 

everyone who has driven a b16 qwith the cat off i need to know.. did it kill ur bottom end? and how was the top end?

 

Bottom End? What bottom end? I went from like 1k to 4k in about 10 minutes

Top End? 4k to 8200 in .2 seconds
