Hey everybody, I'm contemplating getting the PI stuff in my T-bird in the future, although I want to get my gears put in with a TL, a performance d/s and bigger brakes. My question is would it be cheaper to get PI cams, heads and intake, or just swap in a PI motor? BTW, I have a 97 with 57k on it.

I would like to do the myself, but I don't know if I can do it.

it'd probably be just as much either way. You've already got the wiring harness for everything the PI intake does so that'll keep your costs down, but for the price of PI heads (200-300 used?), PI cams (100-200), and PI intake (100-200) you can find a PI explorer motor with the lighter aluminum block for about that much. And when you're doing a head swap its easier to pull the motor anyway, so you might as well just put in a whole aluminum PI motor for the same amount of work and money.

I disagree with Thomas,

I did the PI head/cam/intake swap. Wasn't that bad and for me, It wasn't too expensive..What killed me though and won't kill you, is I had to buy fuel lines, fuel rails, intake tube, etc to convert over...Heads,cams, and intake and new HGs can be had for about $600. Call ted brown for the heads, Dan newman for the "Head change kit", and you should be able to find a PI intake failrly cheap :)

would the compression be higher after doing the headswap as compared to just using a pi aluminum explorer motor? or will they have the same compression

Yes. Explorer motor: ~9.4:1, Headswap: ~10.4:1...

so basically if you dont intend of forced induction the head swap could be a better choice if you want to go all motor?
Without devolving into a PI vs. NPI pissing match, yes, on a stock shortblock the added compression from PI heads will help.

You would :tongue: while the higher compression is good for NA, you can get a lighter motor for the same price or a few hundred more, which IMO is better than the higher compression. The weight savings would make you faster than the higher compression would.

Would it be very difficult for me to install a PI intake and cams on a NPI engine?

97TiBirdMan, as the old saying goes......if you have to ask, you're not ready yet

i was in the same position....contemplating if i should attempt the cam swap myself...after all i did do the PI intake swap by myself....but in the end, i just wasn't 100% comfortable taking apart the engine to that level.....with the help of a fellow TCCoA'er who had already done the swap, it went much smoother than if i had attempted it by myself

just my 2 cents

So do all the hoses, vacum lines ect. fit the PI stuff with no problems?

IMO if you end up wanting to do this: buy a set of heads complete with everythign installed on them. That way alls you have to do pretty much is swap heads and intake.
Just take your time, that's all that really matters IMO.
