3.1 is a Killer!
Hey there...I have a '96 GT that I dropped a 3.1 Phase II in. 1/4 mile times are low 15's at 85 MPH. I beat supercharged 350's off the line and to 60', sometimes to 110'. My line times are usally .450's...the car launches great!
The engine bolts right in, even to the transmission. You have to put a shim into the upper right motor mount, other than that, it's a bolt in. You can visit
www.j-body.org to find out more and see other swaps. This is also a great forum for purchasing performance parts for your car.
My car is dropped for competition on a set of Tokiko AGX gas adjustable shocks with Number One coilovers on Devino 17" alloy split 5-spoke wheels and Wanli Z-rated low profile wide track tires. I have upper/lower strut tower bars front and back/AEM shortram intake, AEM pulley wheels/cam gears, custom header-back exhaust with High-flow Magnaflo cat' into Numer One cannisters.
The car sounds MEAN. It's been on the dyno and is putting out 215 HP/ 185 ftlbs torque. It MOVES when you step on the gas! I smoke Vette's with regularity and Porsches are not even any fun to race. The computer has been rebuilt/replaced...there's no rev-limiter. Top end has yet to be reached. At Hot Import Nights this year, I smoked a pack of 15 Civics/Neons/Toyotas on a quick 10 mile "out and back" to burn off excess feul in our tanks. I hit the parking lot 200 yards ahead of the pack.
I'm going to try and swap out a stiffer, beefier rear end suspension. As it sits now, going around corners at speeds over 60 MPH produce a little understeer, the rear end breaks but is totally controllable and there is NO body lean at any speed reached so far.
I have thrashed it around Mid-Ohio several times and produce very competitive times within my class, usually beating out all the Civics/Neons, etc., losing only to the S2000's, Supras, etc.
Have fun!
