sr20 bogging problems

[spartanmisfit]

Well this all starts a couple months ago. First let me tell you what I know about my car which isnt much. 92 240 coupe. Red top sr20, greddy turbo, greddy fmic, koyo radiator, tial-a-lite elcintric fans SAFC, HKS turbo timer, manual boost controller, and thats all I can see really. I previous owner never gave me a parts list or told me anything really. Anyways, a couple months ago the motor/turbo starting bogging down really badly at 3/4 to full boost. If I could even hit full boost. I've been keeping it around 13 psi. So I changed the spark plugs and it worked beautifully. Fast as hell. Well about 2 1/2 months later it started to do it again, So I bought some iridiums. Immediately under my attempt to go full boost it bogged out worse than ever. I've ried a few different spark plugs and the same thing happens every time. Immediately they foul out. They turn a red color instread of black. So today I checked for boost leaks and found one and fixed it in the intercooler piping. Take it out for a run and bam same damn thing. Now I'm kinda clueless. I'm thinking its eaither AA. It could still be because I havnt changed the spark plugs since I fixed the leak and the ones I have in are fouled.B. My CAS is off, but I dont know anyhting about thator C. My timing skipped a tooth or something.Granted the probloem is much better now that I fixed the boost leak and nearly perfect in 1st and 2nd gear. Now I'm worried it could be something real pricey or bad. HELP PLEASE

Wow really, nothing? Nobody has anything? How about, well it could be your timing, check that, or could be another boost leak or bad cas, or fpr... ****!

You checked the MAF connection to the turbo? Sometimes it can come loose and allow air that is supposed to be metered by-passed. Anyway, its just a thought and something I have experienced in the past. Also, if it was your CAS it wouldn't run because it fires everything, fuel, spark, and the ignitor itself. peace.

bad *** thanks. It cut ould be the maf sensor, but I don't know how to tell because I played with it and it's in there pretty good but for some reason it's zip tied...
