| Hey guys dont think ive ever posted here. Usually just lurk and search for info. But anyways. Ive got a 91 twinturbo ive been building for a few years now and car starts runs and drives fine ive just always felt its never quite made the power it should/could. Mods Bottom end 20 over with wiseco pistons eagle rods and all arp connecting bolts Gt600r turbos Nismo 740s Fmic Ams manifolds 3" downpipes into 2.5" exhaust (literally have the full 3" in my garage to put on this weekend) Single pop intake And tons and tons of new parts, sensors etc. always oem Now as i said the car runs fine, goes into boost quick, its smooth, but just disapointed in the performance. Always felt it should have more. Now i just bought the selin intake and full 3" inch exhaust hoping the car was just choked down. I installed the selin intake 3 days ago and there was virtually no change in performace. I keep driving hoping its in my head, but its not. The selin has proven itself time and time again, i find it hard to believe it made no improvement. What kind of power should this setup make (without the selin and 3")? Please help, ive invested way too much time and money for a 400whp car. Ill answer any questions that may help. Thanks in advance.
