thanx,the nos is just a panic button and another reason to keep the boost down.it comes out to only 150hp gain 1.2 a min,We actually have a spare block in my shop getting o-ringed,It will have the good rods,this engine now is a setup motor.born to blow cause I've got leadfoot,and hate to lose,anybody spun that independant rear out yet.there 7.5's but the knuckles scare me w\the cheater slicks on it.probably should'nt worry,But I busted quite a number chevy rears in my monte.once at 100mph,ugly.last time against my buddies 5.0 it snatched all the mounts loose and hammered my turbo w\vibration,she's fresh again ready for my fuel to get here.atleast seven days from now,I hate mail order,but you been helpful,Thanx I've got my stuff coming from 935 not a bad store ,lines and all. did'nt jump on the lexus afm though,got to be better option than that.Then again this is my first supra.I never thought she run like she does now,and boy is she heavy.haulin some steel!2800 sounds better.Be back in couple weeks w\pics and a testimonial. thanx again bro.
