but a lot less money than a turbo kit and youre probably making as much HP. This is sounding more and more like the answer for us GT owners. (GTP wannabes)...should be plenty of parts availablity as well and you get the benefit of a fresh top end on your engine. I wonder if you could have a blower case and nose drive anodized to add some slick underhood color.

Powdercoat! I started putting an M90 kit together over a year ago, and sold it, some of you may remember.

OMG that looks hot! This whole concept is really starting to tickle my brain. The real kicker is I might be able to pull this off for precious little more than it would take to add my WS6 hood...aint that a crying shame.

And if your gonna get a top end swap I'd opt for the ported blower.

You can always do an L67 swap.

i did while it was out of the car. i figured i would do it right the first time

what would i have to change if i did a top end swap could i get heads from a L67 and intake and injectors and such and then run the pcm from the car i got the stuff from or what??

you need L67 heads, lower intake manifold, and obviously the blower.....things you need to support them are the L67 wiring harness and PCM and other small various things that add up ask drummerboy

No wire harness needed. Just grab the L36-L67 conversion offered by WBS or ZZP. $35~ and you're ready to go.

heads, lower intake manifold, and blower, along with pcm..... that isnt to bad how much should a junkyard charge for those do you think??? or how is the HV3 intake insert from zzp http://www.zzperformance.com/grand_prix/products1.php?id=214&catid=113
would this help me run with some gtps or is think kind of a waste?? would the best way to run with the gtps add the blower.....

or i should say what way is most cost effective??

the HV3 is deffinately a very good investment. But it will only work with an L36 top-end. So if you buy it and decide to go L67 top-end, you will not be able to use it and you will have wasted you money.

I know all the decisions, i just went through it, but i really love my top-swap!

Edit:
This is a list of everything you will need
M90
L67 idler pulleys,
L67 idler stand off,
L67 throttle body,
L67 injectors,
custom PCM,
GTP balancer,
L67 MAP sensor,
L67 heads,
L67 fuel rail,
2 head gaskets,
head studs (or head bolts)
MAP adaptor harness,
bypass valve wiring,
vacuum lines,
brake booster line,
supercharger gasket,
throttle body gasket,
lower intake gasket,
lower intake Orings,
supercharger belt,
GTP valve covers,
GTP valve cover gaskets,
coil pack bracket for 99+ cars,
lower intake from an L67,
M90 bolts,
and new rocker bolts.

doesnt the later model L36 (2004 up) use an aluminum intake...I wonder if this intake is as good as the plastic intake with the new insert? Of course all that is moot if you go with the blower...didnt one of you guys add a mild cam as well?

i should just go to the junkyard and see how much they want for a wrecked gtp i know it would be cheeper for me to buy the whole car and then take what i need from it or has anyone bought motors from ed? what does he charge for a gtp motor??

I think Ed charges around $1k for a fully equipped motor, depending on mileage. Just email him and ask.

drummerboy did the mild cam with the swap. i am doing 1.9's instead
