jacksoncharger problems

I have a 2000 Integra GSR i have a JRSC on it. It used to run great. it ran 13.6@105 on street tires. then it has got slow. it is real boggy bottom end and it all the sudden hits about 75-80% power after 6 grand. also it detonates with any more than 8 degrees timing. my fuel pressure is good, my A/f is good, and my boost is all there (11psi). the only thing i remember before it got slow was i ran at the track w/ 112oct uleaded race gas. also i had the pressure switch relay swapped until i called jackson and got the right one. my air temp sens code is being thrown after 6 psi. i called jackson to get wiring schematics but they were not much help. no one can figure out what is wrong with my car. i have also done compression test. 3 cyl ranged from 155 to 165 psi and one was 185 psi. what is factory compression on a gsr? if any one has any suggestions please let me know. :flash: my car is slow please help i want to rape v-8's again!!!!!!!!!!

Have you checked the cam/crankshaft alignment...?

One tooth off on any given cam, can cause up to an 18 degree change in timing. Since you can't take it up past 8 degrees, that sounds like whats happening to me....

The only other thing, is the O2 sensor took a hit when your ran the 112 octane.

You might do a search for a forum called "Forced Inducted Integra(s)", are something like that. I have not been there for awhile, tho....

Just some thoughts....

"Noth'in like Induction..." ;)

One thing...In another thread on here you mentioned you didn't have an inter/aftercooler...Running 11 lbs?? Get one...Also, yes, check your O2s, 112 octane isn't good for them.

the o2's are fine i have already checked them. but thank you for the suggestion. i will check to see if my cae is top dead center... im am pretty sure it is though.

does jackson make an intercooler for a gsr????

does any one know any east coast shops that specialize in JRSC?

Give JR a call and see what they have to say about any install shops. "Some" Honda dealers will install them. While others will stare at you like deer caught in headlights...

They should also be able to answer you Q's on the cooler, too...

They have had some bad PR, however with all the above mentioned probs I had. They were always there, or re-turned my phone calls anytime something was under question...

"Noth'in like Induction..." ;)

thank you, but i have come to the conclusion that i burnt up my piston rings. so now i am going to lower compression pistons so i can run more timing on the street, and it will be a lot more streetable... down the road a little bit maby sqeeze a little!?%*$


Thanks for the help.
