First of all I have a 91 240 with a sr20 (stock - ka mounts, sr fan and shroud, sr radiator, sr smic w/duct and factory plastic piping, clutch, no LSD, crappy struts, and some wonderful champion copper spark plugs.) (aftermarket - Blitz SSBC, Blitz bov, apex turbo timer, 3in turbo back w/heavythrottle 3in cat, K&N filter,walbro255, autometer boost and A/F, eibach crappy .75in lowering srings, enekei knock offs 17x7.5 w/no traction 215/40 nitto 450's, and crossdrilled front rotors.
I went to the 1/8 mile dragstrip friday night. I had to drive 50 minutes to get there so my car was nice and hot and not running the best it could. I experienced a lot of stupid problems, the main one that pissed me off was I had the boost set at about 14 when I got there, but when I ran it spiked at 12 and settled at 10 so I cranked it up all the way and no change. My buddy was sayin it could be heatsink problems with the smic. So I let it chill for a while and sprayed down the intercooler with water. Then I put some 104 race gas in and back off I went I had been running 9.3, 9.4's this time I ran a 9.1 at 81.27mph 60ft was 2.27 and with tons of wheel hop, this was the best I got it to, I felt pretty good about it since that time I hit like 12psi and held it. I want 8's really badly though. Yesterday I changed the oil and saw some fluid spots on the ground while I was down there, only back by the tranny. Sure enough it's the outputshaft seal my question for you guys is can I use the seal from a maxima rear drive tranny or 240 tranny?
The other thing is, the car will boost 15 from 3-6 grand until I've been driving it for more than 20-25 minutes, then it starts spiking at 13 and settling in around 10-12. (daily driving is done at stock boost, but sometimes you get a little bored) Could the bov be leaking boost , cause all vacuum lines are secure and new (I put in the motor 12-20-03) or could it be that its just running hot?
I greatly appreciate any answers you guys have.
