LS2 GTO vs. 300ZX TT

**whiteghoztt** · 12-09-2006, 10:56 PM

Hey everyone,
My friend has an almost brand new GTO w/ LS2 motor ( has like 12k miles, beautiful black), with automatic transmission. He had been anxious since he got it to race me and was pretty confident that he would beat me pretty badly. Now, I'm not stupid, I know the potential of the LS1's as I've been on eastern f-body forums for years and have been apart of a lot of cruises, etc, with them, (seems like half of my friends own one).
I drive a '94 300zx TT mods include turbo back exhaust, jwt pop cone intake filter, pullies, and manual boost controller set at 15.5psi and dynoed 376rwhp w/ 394 rwtq in 96 degree summer heat, stock turbos, stock injectors, stock intercoolers, stock cams. His GTO is 100% stock, but I still figured... it's a LS2.
We ran from a light roll ~20mph he beeped the horn and I waited for him to hit the gas before following suit. He hung at my bumper by the end of 1st with me spinning. I stayed in it through midway of 4th. I had at LEAST 7-8 cars on him, wtf?

Afterwards we were talking and said he barely chirped 1st and that he for the most part hooked up and saw me spinning as I passed him. He said his run couldn't have been more perfect and that he didn't want to go again

Now... I'm a HUGE fan of f-bodies and GTO's, but 7-8 cars? My friend stood outside and filmed us and it looks even worse on film, so I'll stick to what I can see from off my mirrors. I had expected to put some lengths on him, but seriously I raped him pretty badly. I'm rather disappointed, can anyone explain this?

I wish I was that light, it weighs roughly 3550 w/ full tank without me. I know there is some weight difference, but only a couple hundred pounds. What do the new GTO's put down? Do the auto's lose a large amount through the drivetrain on those?

Your about dead on with the 1/4 times. I estimated about the same based off other Z's with my mods.

**tonyjnjz** · 12-09-2006, 11:43 PM

well the gto should run real low 13s to a few in the high 12s.....so your a full second quicker than him.......hes prolly putting down around 340 to the rear wheels .. have u raced a c5 z06 yet? that would give u a much better run.....same horse as the gto with about 500 less lbs

Man, do you know how hard it is to find a stock or near stock C5 Z06 to race? lol, I've tried! Trust me

Yes I do, none with current wheels or with my exhaust. Need to take a few

Here's some of what I have.

Sorry if they are to big. I need to take a couple new ones :P

looks sweet man....whatd u get for your new wheels? any more potentional out of your stock turbos or are u pretty much at the top of what they can handle?

**ss~zoso~ss** · 12-10-2006, 09:45 AM

na man that race seems right, your car probably weighs less and puts down like 30-40 more hp than his does

I bought Yokohoma AVS Advan VS-5 Wheels Front 17x9 255/40/17 tires - Rear 18x9.5 275/35/18 tires

I just bought upgraded side mount intercoolers and larger injectors so I can fully tap out the stock turbos. I'm looking to put down about 395-410rwhp on the stockers after that on pump gas. I've never dynoed on race gas, but I might try it this year sometime to see what I can push.

Them 300ZX can run some sick times .. My Buddy runs constant low 10s ..We started talking because he put a th400 to it ... He did send his turbos off and have them so they spool faster,,, dont know all the details in that ..
He is full cage now and may put NOS in her to get it down in the 9s .... I can give you a update if you want ..

yeah man, let me know how that works out for him. Sounds like he's got a lot of weight reduction going on though. There are a couple street legal Z's in the 9's right now without nitrous with full interior.

Your friend should have no problem if it's setup right.

**snaggeltooth** · 12-10-2006, 01:56 PM

well I only mentioned the part about the Turbos because I thought that was what relly put it over the top.. I know he said since he got the cage it is quicker but not as fast ... Im thinking 127ish ... Ill get a rundown Monday...

127 trap? wow.. that's obtainable with stock turbos almost.

I remember he said the rules make you have a 7-point if you go over 120 ...

**Raoul-Duke** · 12-11-2006, 09:52 AM

wow..i never realized 300zx's had that much potential runnin stock turbos and bolt ons...sweet kill man

**snaggeltooth** · 12-12-2006, 12:21 PM

ok Eric , guy at work, Last run was 10.58 at 130...60ft time was 1.48... beside the Turbo kit .. He gave the intake a port job ... Regular bolt ons, and a chip ... Said when he put the th400 in that made a world of difference ..Said he is going to get a new Garrett set up or put a 250 shot to it ...
ps...all internals are still stock..
