Supercharger or PI SWAP

Azarello · Nov 28, 2005

OK, had my 96 gt for about a year and have done very little mods besides the CAI and a cobra clutch. Now she has about 100k on her and I want take it up to the next level safely. I recently have been considering a supercharger. My question is, if I get a supercharger I can not do the pi swap right or worng? If not should I just get the pi swap with gears and exhaust, or just go with the supercharger with intercool. Pro's and con's and or suggestions for which supercharger I should get for my 96gt manual. Thanks.

You could do both of them, that wouldnt be a problem, but if your gonna supercharge it at 100k you probably wont last to long. I would do the heads, and if funds were available, build up the bottom end and blow it while i was in there.

keep in mind that doing the PI swap on your 96 will bump the compression ratio up higher than a stock 99+ 2V, so you might want to do nitrous instead w/ the PI swap.

Like STNG_96 said, while you have the motor apart for the PI swap, it wouldnt be a bad idea to have the bottom end built up to prepare for some serious PSI from a blower.

good luck

I say BLOWER. Injection is nice but been blown feels soo much better.

I would do ported heads, cams, longtubes. would cost you about $2800-3k but the power you would get would be as good as a supercharged non PI car.

you can still boost a pi swap you just can't go much over 6psi becasue of the compression.

if you stay n/a you won't have the reliablity issues to worry about.

i say do the heads. putting a supercharger on the NPI heads is like blowing through a straw.

Well you can get a PI intake and PI cams for dirt cheap and run a centri blower.

how much does the average person pay for the pi h/c/i combo from a used car?

NPIGT · Nov 28, 2005

I got my heads with cams and the intake manifold for $450 shipped. Now I'm getting ceramic coated long tubes, mid pipe and a diablo predator. I say head swap it with cams and all the bolt ons with nitrous. You should be happy.

If it's not redneck, is it redhead?

Just curious as to what movie that was from. Just a hint...?

Oh yeah, I too would lean towards the centrifugal blower. Maybe an exhaust change in the future, take it from there! Anything else is GREATER gains.

Now you got me curious. Who has done this? What is the advantage over the stock cam w/centri?

At 100k miles, why not do the PI swap and have a whole new top end? You do not want to S/C a headswapped car even with 6psi as one poster claimed. It will certainly blow up.

If I am not mistaken its from American Psyco.....

You could always install the PI cams and valve train in your NPI heads, have a decent port and polish done, install the PI intake and add the supercharger. That's probably the most power you're going to gain, from the least amount of money.

this is good info...and can be dirt cheap as said. If you look you'll find the PI cams for as little as $50 and the PI intake with alum crossover for @ $100. Then if you really want to take it to the next step do as Gearbanger suggested and get you NPI's ported and have PI valves installed. This will ensure you never have a compression issue.

thanks great suggestions!

o0akoni0o · Nov 29, 2005

don't realy wanna hijack this thread, but since i plan on swapping out my cams to go along with my pi intake then adding a centri, are there any significant gains that justify the price difference by going with some aftermarket cams opposed to the pi cams?

streetstang03 · Nov 29, 2005

you might as well upgrade to some stage I or II cams while you're doing it. you'll definetly get more power out of aftermarket cams than the stock Ford PI cams.
