Swapping a pi motor into a non pi car.

[Hellspeaker]

Hey whassup. I was on svtperformance.com and my buddy told me about this site. I feel right at home here! I have a 1998 gt and im about to put a 1999 pi motor in it. I was wondering what all kind of stuff i should be looking forward to screwing up while doing this. Just need some advice on what ill have to change or is it a direct swap?

Coil pack mounts and extra coolant sensor in the intake are only big things

 

[Hellspeaker]

Oh okay. What kinda coil mounts am i going to need? Anything other small stuff i should worry about?

I used my 97 GT coil pack mounts on my setup....and agreed with extra sensor in manifold

depending on year and cast you can use the whole front cover.

As said its a 1998. Hopefully ill get the money up to buy the motor soon. Gotta sell these Termi wheels first

the swap was no big deal, but I did get a romeo PI engine so that helped considering i was able to reuse my front cover...

Ive had my car setting in my yard for sooo long. Like 8 months now and its killed me everyday not being able to drive it. So whats the power like when you finally get the swap? I wanna go n/a for a while throw me some 4.10s in it exhaust and such.

I recently swapped a 2001 PI motor into my 1998 GT.

The swap was very straight forward. Just just need to reuse the timing cover from the NPI motor so you can use the coil packs. All the 1998 wiring is used. I also replaced all gaskets on the motor.

Here is my build thread discussing the swap in detail!!!

My modded npi dynod at 186rwhp. Then the pi with same mods netted 242rwhp and 280rwtq...

Big improvement lol

 

[Hellspeaker]

Oh yes. Yeah im definately looking forward to it. I would like to do some kind of f/i down the road at some point. Ive heard the stock motors can handle around 600hp before stuff starts breaking...i only want about 400.

 

[vermilion]

its good to 450ish hoss.

 

[Hellspeaker]

Yeah im just gonna do gears exhaust and a short throw for a while and beef up my suspension and do some body work. Then the real fun will start.

200 hp can break a motor easy. It all depends on how efficent that engine is which will determine how much power it can handle

just to show how crappy non pis are....I had every bolt on in the book (longtubes, off road x pipe, catback, throttle body/plenum, cai, udp's, tune....and through an AODE I put down 202rwhp.....your talking thousands of dollars in bolt ons to be a tad over 200rwhp...I then added a PI manifold, PI cams, and a blower and wala 400rwhp

Put a 04 PI motor in my 97 after i threw a rod in the NPI motor. With every bolt on aside from headers, and a tune my car made 255/292. Thats 44 more hp and 32 more ftlbs than my old motor(211/260). It was a nice improvement to say the least.
