upgrade
 

I am looking to upgrade my z31 even more. The only thing that it has right now is an extra 50 horespower added by Calloway. What would u guys recommend and in what order. I want to be able to blow all the civics away(i can beat most of them now but not all of them) help!!!!

Re: upgrade
 

What motor do you have? The NA or the turbo? And what did Calloway do to add 50hp? And when was it done? Wasn't aware that Calloway ever did anything to Z cars. New one to me...

Re: upgrade
 

I have the turbo z. The woman i bought it from was dating a guy who worked at calloway. they rebuilt the engine at 70,000 miles and did some extra work to it. when i can find the reciet she gave me i will tell u what they did to it but i dont remember off the top of my head

Re: upgrade
 

sounds pretty quick already...you've got about 250 horse. ever consider Nitrous? I mean, the engine is built, so it would be able to handle a hefty shot...]

might also consider a manual boost controller, and an intercooler...crank up the boost

Re: upgrade
 

i was actually thinking about getting a fifty shot of nirtrous however my only concern would be the fuel pump. I would not know what to get so it could control all of that extra gas.

Re: upgrade
 

whats a calloway?

Re: upgrade
 

nope, the stock fuel pump is good for about 375 horsepower, believe it or not...

Re: upgrade
 

calloway is an aftermarket performance tuner. He primarily did Corvettes, but expanded to include at least a few other GM products.

Extremely nice, extremely fast.

Re: upgrade
 

so you haven't answered the previous question, what exactly did calloway do to your engine to add 50hp? if i can get a quick 50 hp like that i would take it!

Re: upgrade
 

A quick 50hp on a turbo is easy.
open up the intake.
open up the exhaust.
up the boost.

Re: upgrade
 

is that all? damn it..i already did that..grr..i was thinking calloway did something else to the engine that made it faster...

Re: upgrade
 

I don't know what Callaway did. But that's all you have to do to get a quick 50hp.
