Nice! my Z is my Daily driver, so I think i'd like to cap myself at 600whp worst case 550ish

 

Expect to spend at least 5k after all is said and done for a built bottom end. Don't let that $1,099 fool you.... Talk to your shop and don't bother looking at Ebay for these things even though the Eagle rods and Arias Pistons are a great choice

 

You're going to spend AT LEAST another 10 grand if not a lot more getting anywhere near 600whp out of that car.

 

well he'd have to get a TT kit first like he said

 

+1 we'll see how things go.

 

+1

 

Any word on the official diagnosis yet?

 

nope probally tomorrow keep u guys updated

 

I read your other thread on ChicagoZ.com, good luck with the sale of the SC! Can't wait to check our your new setup/engine build... going with the APS TT?

 

You should keep the Vortech, and get the biggest stroker kit you can find. You may not get 600whp, but you should be able to get 500wtq.

 

I think it'll be hard to get much more torque than about 450tq at the wheels even with a huge stroker kit and massive headwork

 

There is a girl here in TX says she is getting 485wtq with 3.7 and TT.

 

4.2 and 10-12 psi should do it. Wishful thinking maybe.

 

TT, meaning twin turbo? 485tq is probably no problem with a twin turbo kit


increasing displacement with a supercharger only increases the power in the form of the NA power gain. The vortech and all other superchargers for the Z don't have a wastegate to maintain a constant boost pressure. Actually the supercharger only makes what it makes so it doesn't have extra power to bleed off out a wastegate

the 4.2 liter would probably gain 45 or so tq at the wheels

 

Change the pulleys. There was a Mustang at the track with a Paxton/Novi SC that did three wheel stands in a row. That was cool!

 

As far as I know, the OP is now going for a TT/built motor setup... He's listed the SC for sale on our local site if anyone is interested.
