anyone can tell me if after i do the swap on my 98, is it gonna just start and run ok, or is there other things i need to do to get it to run rite, like injectors, maf, pressure reg, or what???

it will relearn its setting to run with the pi swap,but a tune is recomened(sp) for max power.

along with my pi swap, I did a tune/h pipe and dropped a good amount in the 1/4 (almost a whole second)

Yea the stock computer, injectors and maf will work fine. when I got mine tuned Tim did a baseline with stock settings and I was at 250rwhp. after he tuned it, it came up to 271rwhp/281rwtq with the mods in my sig except the procharger.

ya it will run alright because i'm runnin an 01' 5.4 with a 98 gt computer but def. suggest a tune soon just for more power!!

xplicit_red281gt

yeah everyhting will work well but u have to get a tune asap bro. hey chris u made 371 with procharger or without

Chris98Gt

271rwhp/281tq with stock pi heads & intake, stage2 npi cams with lt headers and catless hpipe. after I put the procharger on it, it now makes376rwhp and 360tq.

as far as the tune, do i NEED a custom tune or will a hand tuner do, also im at 92k on the clock, i have the block on a stand and have the pistons and rods only removed, iwas thinking that maybe i should drop the compression for a possible supercharger later on down the road, if i do this do youll think it will run OK, or will it be a dog? should i grind out that intake wall??

Chris98Gt

Idk what intake wall your talking about, but the stock computer will run the car fine. If you want max performance you need a dyno tune to fix the fuel curve and what not. If you want to run more than 8psi I'd get atleast a set of pi pistons to swap or get a set of forged lower compression pistons and rods. My short block had 101k on it before the swap so If yours was still in good working condition I wouldn't worry about doing a pi swap.

u will need the 99+ coolant tube, water pump o-ring, gaskets (intake set and head), head bolts, im not 100% if u need that specialnipple
