I posted this on the engine swap section and only got one answer. I was wondering if you guys had more insight. He said that with the sdpc vortec tpi intake and the edelbrock runners i would get approx 365hp. is that about right?...other than that is this a good deal for $2000??. thanks

thread can be found here.

Unless your running open long tubes, the power will be quite less. and i bet that engine dyno was done without any accessories, so that will bring down power as well. and in the end, make sure you have some slightly bigger injectors, and a good tune to really get that power, otherwise you wont be near what you could achieve with it. oh and stay away from nitrous with that choice.

dont care about the nitrous...turining this into my autocross only car, but curious as why should stay away from it?. ALso, when you say bigger injectors do u mean 22 or 24lb?. whats the potential estimate of hp for this. 325hp +/- 25hp? if so, im guessing my money is better spent just saving it and piecing together my own motor

damn man I wish I could make a decision. I not sure if i could piece together a better motor for $2000.

Putting a motor together for 2 grand is hard to due...Money goes FAST!!! If it's a good running motor for sale...it might be worth it....

just buy it with some 28# injectors, I said no nitrous cuz they have hyper pistons.

One of my dad's previous combos was some Iron Vortec heads, SLP runners and a ZZ9 cam and I think it made around 305 RWHP and 380 TQ thru a T56.

But I would stay away from those heads because of the need for the special Vortec intake, and the lack of internal EGR means you need to hook up an external EGR off the headers like the Corvette TPI does.

Im not worried about emissions so should an egr matter?....cant i just use a block off plate and provision my chip for non-egr?

Kevin91Z · 04-01-2009, 01:36 PM

We live in California. Yes emissions matter. I hope you're at least keeping the cat on it.

You will need to get the chip customized to remove the EGR code, as you said.

car will be used as an autocross vehicle only. Wont be street driven. Only towed, and even if i needed to smog it, i have somewhere i can take it to pass with or without cat/egr/air...Im beginning to really lean towrds this purchase. Thank for the advice guys!
