370z vs Wrx Sti

Chuck33079 · 11-20-2012, 10:12 AM

You'll be fine at or just under 500 whp (dynojet) on the stock block, assuming the tune is spot on. Budget 15k or so to really do it right. 500 whp is a lot of power. You might find out that you're perfectly content at that level. A turbo Z is a handful.

lemon-fresh · 11-20-2012, 10:41 AM

If you are looking at around 500whp, I'd stick with the Z. Will probably end up being cheaper to hit those numbers with it.

I'm going to second the issues with 400+ whp sti's. I have a couple friends who have had to rebuild their engines and were pushing those numbers.

If you are so obsessed with high hp you might also consider another platform entirely. Higher displacement v8, old supra?

If you plan to track get a Z. If you want good power get a Z and TT the baby. If you want to carpool get the WRX.

Think longevity. DD not an issue but why go big power if only a DD? Track duty is high wear so what car at high power usage lasts longer/costs you less to keep the same performance over time?

Chuck33079 · 11-20-2012, 07:32 PM

I did talk to GTM. And then I bought a ton of stuff from them. I'm going from experience, not what I've heard.

Ok, let's do some math. The car cost 30-40k. The turbo kit's about 15. The motors from GTM look to be about 25k. That's about 80 or so, and we haven't touched the fuel system. 2-3k. Probably going to want some wider wheels and tires in the back to handle the power. That's what, another 4k+? Oh yeah, clutch? another 1k. So we're at 77-87k without labor depending on if he bought a base model or touring.

Maybe I'm being too vague. I'll use my numbers. The car cost 40. The turbo kit, clutch, flywheel, etc cost 15k. Another 2k or so in random stuff like springs, sways, endlinks, camber arms, radiator, etc. Call it 5k in labor so the math's easy. So I'm at 62k with a bone stock motor. Add in the 25k GTM longblock, 2-3k fuel system, a good bit of dyno time, etc and we're still not too far off the 100k mark. close enough to it to consider other vehicles that might be able to make 600whp a little easier.

Just the TT kit is 15K?

The base kit isn't, but that's what you'll spend to do it right. 3" downpipes, EWGs, ceramic coat everything, powdercoat piping, etc. I included the cost of my exhaust in there, but he'll need some form of 3" exhaust. They cost around the same. Sorry if I came off as combative, I just unfortunately know how much this costs. I was dumb enough to keep a spreadsheet. OP, if you build a 600 whp Z, throw away the damn receipts. You won't want to know the final total.

ya I am not sure where he's getting his numbers from from what I can see you could have bought 2 tuner kits for that price!

sorry wouldn't safe the preferences for vehicle and what I had searched so you'll have to do it yourself
GTMPOWER.COM

even in this article(the first post) it's only $7500 for the TT kit

From the GTM invoice on my desk, unfortunately. And the one from Fast Intentions, and the one from CSF, etc.

red6spd · 11-20-2012, 07:46 PM

Not combative at all. This info is very helpful for all of us and you for sure know a lot more then I do since you have done it LOL. The local shop in my area will do a STG 1 GTM installed with an OS Giken clutch/flywheel, 25 row oil cooler, Tune for around $15k. Exhaust will be more of course. I know that's STG 1 and I'm not getting into the full build of the motor but that's good for 450-500 wheel.

And that's where he should stop. Past that point the $/hp curve gets wacky.

Your local shop isn't too bad on the cost, but you'll still need another $5k of other stuff. 3" downpipes, exhaust, radiator, etc. You only want to do this once. The real bastard about this is, the numbers look daunting and hard to swallow, but it's soooo worth it.

FYI, If you're thinking about TTing a Z, keep some funds in reserve in case something goes bang. It would suck for someone to be making payments on a car that doesn't run.

Ahaha I have a base model. I was on gtm page looking at stage 2 tt kit it was about 7k

7k to start. Once you add the other things you're going to need to do it right and reliable, double it.

LMBmikeZ · 11-20-2012, 08:05 PM

weird you should look into that cause you got over charged I know a guy up here in Canada that went GTM TT and he spent <$10K

are you including instal? some of use are capable of installing it ourselves which is a huge savings and great sense of accomplishment!

Lol. It's funny you think that the kit is all you need. If we call the kit 8k, then we add 3" downpipes for 1100, oil cooler for $500 or so, CSF radiator for $700 or so, Clutch and flywheel for another 1k, 3" exhaust for another 1500-2k depending on brand, boost controller, ceramic coat all hot side piping for a couple hundred, powdercoat all the intercooler piping for another couple hundred, gauges for another $500.... No, that's not including labor.

I'm not saying you have to spend 15k. You can cut corners and do it for less than 10k. I chose to do everything at once, and get everything I need to make it as reliable as possible.
