An lightweight crank pulley (not reccommended) or electric fans will help get you closer. 1989 Toyota Supra NA-T Save Share Johnny Dangerously · Not ur jizz, not ur bizz Joined Sep 16, 2002 · 6,571 Posts #4 · Jan 8, 2004 Only show this user Full 3" exhaust from the turbo elbow and back.

Or do ya'll recommend using different parts. Save Share GrimJack · Registered Joined Nov 23, 2003 · 2,650 Posts #6 · Jan 9, 2004 Only show this user Depends on your goals, spare cash, and availability. If you really are going to quit at 300whp, stock parts should suffice quite nicely. If you get the bug and end up with a 500+ whp monster, you'll be bitter that you didn't replace a whole lot more of the internals while you had it apart the first time... Seriously tho, the headgasket is the only serious deficiency in the 7M. Fix that and you're set. Want your questions answered? Read this.

Personally, I almost always pick up my parts locally, but I live in a big city with a lot of import stuff available pretty easily. Perhaps someone else will chime in here.

Click to expand... this is on track, u dont need 550's or a lexus afm. just intake, exhaust, a piggy back, new hg, and take it to a dyno for some tuning. tuned at 15psi u can get close if not break 300rwhp depending on what condition the motor is in oh, and with about 300rwhp, you'll prolly make 330+ ft-lbs http://www.youtube.com/luvmysilversupra Save Share G Guest · #12 · Jan 11, 2004 im def. with boostin 88T on this one. Joe is da man! you really should be asking how to get to 400 RWHP cuz 300 is just too damn easy! of course, you probably shouldn't ask at all, since it has been covered 100,001 times and searching will give all the answers you need.
