how much rwhp do u think ill put down with and without nitrous
do you think this is for the street

uberstang1

I'd say around 280rwhp, and I don't see why it wouldn't work on the street,all it sounds like is a cammed 2v with minor head work.

joshb

so build a pi 4.6 for 2gs or swap a 5.4 for under 2gs and build off that

Convex

I would just do a PI 4.6 and rear gears to start with and add the rest as you go because there is so much more that stock PI motor has to offer once it's paired with the right rear gears and if you need more then add NOS

joshb

so drop 2 gs on a built 4.6 for 280 hp or throw a 5.4 in for under 2gs and have 280 then build that

Gt04

I'd do the 4.6. 5.4 swaps are a bitch on these cars due to lack of space. I started a 5.4 swap on one of my project cars and said f that and sold it. Very time consuming.

joshb

from what ive read its alot easier on sn95 just put it this way it would be like swapping a 4.6 into it its the same engine basically

uberstang1

The engine bay is identical from 94-2004, so there is no extra room or ease when doing it in a sn95.

joshb

im talking eletrical but is there such a thing as a pi swap 5.4 taking a npi block and putting a pi heads on it with just cams people are making 300 rwhp 300+ torque

UPRSharad

Should make plenty of power. Just make sure you budget for suspension & tire upgrades, because you'll need them with that setup!
