yes, unless you P&P your not going to notice a big differance

an 89-93 blower pully on a 94-95 blower will increase boost 2 psi. so you will get slightly better times

 

Well seeing as the windstar is very difficult to port I haven't had that done. But I have had the lower, which is off of a '99 'stang, done.

 

So just for clarity's sake, i'm looking at high 13's in my brother's 98stang/95SC engine swap(89-93 pulley, dual exhaust, hand held retune). And high 14's from my 96 stang/97 4.2L f-150 engine swap(windstar topped, p&p lower, shift kit, 4.10's, t-lok'd rear)?

 

add tunner to ur 4.2! as far as the s/c 98 i wouldnt go backwards i would m112 it. and drop the m90 in the 95

 

The main problem with the M90 is efficincy.

-Swap the rotors for those from a recent model Grand Prix GTP because the teflon coating is better
-install an aftermarket heat exchanger
-get a new ported and remachined blower housing.

And after all this i'll still have spent less than a M112 install. And single ports actually are able to flow quite well. Throw on some SSM stage 3 heads and overspin the blower, sounds good to me.

And the 4.2 will of course be tuned.

 

Ok, so, no other thoughts?
