Thread: Nick's 98gt Build from slow to peppy

    Nick's 98gt Build from slow to peppy

    I joined this forum owning a 97 Supra converting it to a single turbo. Unfortunatley some things came up in life and I had to sell the supra. Good news is that it is being built into a 800+rwhp monster.

    Now to my new venture.... Having already owned a few stangs I decided to try my luck and build a 2v track car. I wanted to start from scratch and started looking for cheap rollers around my area. After about a month of searching I found a running 98gt 5spd a couple hours away. I went and checked it out,,, car had 145k on it. The NPI 4.6 was worn out, dirty and poorly maintained, shocks and struts were blown out, brakes were trash, interior was awfull. The good news... straight body and zero rust. Got the kid talked down on price and brought it home with me.

    Photos when I bought the car (Pretty Bad, looks like the car hadnt been washed in 10+ years)






    It also had a good sized dent on the passenger side rear bumper..............

    First things first car got a full wash to see all the damage. Suprisingly the factory paint wasnt too bad. It will need clay bar'd buffed polished and waxed but no faded paint or too bad of scratches. The worst is the front bumper (which will need to be re-sprayed).



    Was able to pop out the dent and somewhat warp it back to shape.... 2hrs of the heat gun and various pry bars to snake behind the bumper support.....

    Looking like a good start! The nice thing about SN95's is that they hold up really well.

    Great thing about those NPI 4.6 engines is they gain a nice boost in compression from the PI top end along with the better flow.

    What are your overall plans?

    Now comes the fun part. Finding cheap ways to make this car faster. If anyones knows about the NPI 4.6's they were the engine used in the 96-98 mustangs and only made like 225hp and 290tq. In 99 they came out with PI (performance improved) engines which up'd it to 260hp & 302tq.

    Luckily ford decided to put the PI engine in vast amount of cars in the years ahead so they are easily accessible and cheap. I was fortunate to find a guy locally with an 02 Lincoln Town car with under 100k's on it so I pull the trigger!

    Hello PI Engine



    With the new engine purchased the old one needed to come out......

    Thanks, its a fun car to work on which is probably why this is my fourth one lol. I decided to go with a full PI engine swap. That way I can do away with the NPI engine that was in it. It drove home just fine but I could tell from meeting the owner that it has had a rough life lol.

    After removing the engine I decided to inspect the engine bay and core supports to make sure nothing was out of the ordinary, unfortunately I found this.......


    Looked like the previous owner had been head first in the ditch at one point which would explain why the front bumper was in such rough shape. Luckily it didnt do anymore damage besides what you see as the fenders/hood lined up just fine and front bumper support seemed untouched.

    I was able to bend both sides back by using my imagination with a scissor jack and a couple of 2x4.

    After (Still have more cleaning to do)

    Got some new seats, I think they will work just fine.



    Thats basically where I'm at right now with the car. I have quite a few boxes in my house of parts that will be going on this thing and just got done ordering tons of suspension stuf so there will be more updates to come.

    I posted a little too soon!

    Looks like great progress, you will certainly not regret going with a full PI pullout.

    I think it should be a fun car. I will have alot more money invested in the chasis and suspension than the engine this year so we sha'll see what the near stock PI can pull for times slips. Plan on running either a 3.73 or 3.55 gear.
