I need to make a new video.

SwivelHips, just a heads up: the early 03 sedans shift differently than coupes and late model sedans. The manual mode is more of a top gear selector - that won't change (though I have heard of a firmware update that may address this).

Now that I have sticky tires (R888), at least in the higher gears, I can leave it in "D" and my GTM-5AT handles it just fine (quick and firm shifts). I admit, I never floor it in "D" though. Too unpredictable if the trans downshifts twice, then the car turns into a rocket.

Looks and sounds good. I'm thinking I'm going to stick with the car I have and do a bit of body work, upgrade the tranny and get the Turbonetics single turbo kit. I just want 4-450whp and I think it will suffice. Unless I get the mod-bug again.

Thanks. Yeah definitely upgrade the tranny if you are going to get boost. I had my tranny built locally here earlier this year. 400-450 is a lot for the stock motor, I wouldn't go above 400. rcdash is right, I don't floor it in D either..the car is too unpredictable if you do that. With my power level I hook up pretty good in 1st gear with 285 nitto invos on the rear. I stepped up to NT05's for the track and I had zero issues with traction coming out of corners. I just have them for the rear though. Once I get them in the front the car should be on rails

I can't help but notice your name is Canadian, just wondering if you had any work done in Canada and where it might have been. I'm trying to locate a place where they would be able to do the tranny upgrade.

There are many threads on it that identify it's weaknesses (particularly over at my350z). It is no longer sold as it has been usurped by the Powerlab kit, which addresses many of the weakness of the prior ST kits.

So basically what you're saying its a hunk of junk? lol. What budget minded turbo kit would u guys recommend without sacrificing quality. I'm leaning towards the GReddy TT kit.

How much do you have to spend on this project? That is really the key. You can also look at used parts.

Btw you have PM

Is anybody running two tranny coolers? should I buy another one or replace the smaller one I have on the front that is already mounted. I know some guys that are running two. My tranny overheated once and went into limp mode after coming up and down an mountain....I know I need another one since it overheated, obviously the smaller one isn't sufficient I dont have a built tranny but do have the VB upgrade and highstall toque converter. The smaller one in the pic is what I have mounted in front of my intercooler.

+1. You don't want to create too much restriction, but parallel coolers might work well (not in series). I would just get a single large cooler (11 x 11 x 1.5) and get it to fit.

You should change your ATF by the way ASAP. At that temperature (above 300 degF if you went into limp mode), you have very little life left in the ATF.
