I am curious about them. I know someone who has one, and I was talking witih him about what it would take to run in the low 11's. I have a procharged 98 C5 with 500 rwhp, but I was curious where he'd have to be in his 300ZX TT to be able to hang with mine. I have seen some that get in the 500-600 rwhp range, but with their weight difference, I'm wondering what it would take for him to get it there. I'd actually like to see him build it to make it a good race, but I have no idea of the cost.

The car produces a bunch of torque, but what experience does everyone here have with them?

Have a couple of friends with some TT's, one of them has over 500rwhp and has the block bored.40 over forged internals and some monster turbos...I guess.

Well, it's a 3.0 24 valve twin cam V6. Box stock they were 300hp cars and are quite heavy for their size. I've owned several older Datsun Z cars (A '73 240Z, and two '83 Turbo 280ZX's and the 300TT is the most refined of all of Z's, including the new 350Z.

Beyond that, they're a major PITA to work on.

He supposedly has the car being worked on by a well-known 300 shop near Atlanta. The dude is kinda known to tell some insanely rediculous lies (still a pretty good friend, though). He said he is planning some intercooler, turbo, and fuel system ugrades, and he is changing the computer. I know nothing about 300's, but he said they blew the stock motor on the dyno. He said it was around 575 rwhp when it did. I'm calling BS simply because I know the guy real well, but it sounds like BS anyway.

He said the whole upgrade is costing him $16k. He said the motor was $8k to replace, but he didn't say anything about going back with anything other than stock (wtf). I hate repeating all this because the dude really does tell some outrageous stuff.

I'm hoping he does come back with something that will flat out fly. It would be dissappointing if he's just telling yet another off-the-wall story. I know the car went to Atlanta because his brother told me he flew out there. I just hope he didn't spice up reality too much.

the 300tt use to be considered one of the 100 best cars. Stock the car is pretty quick, but like said above it is rather heavy. Depending on the mods, and upgrades that car can be pretty fast. The 2+2 300zx where a lot heavier then the coupes. For his car im sure if he modified the turbo, and did some other engine work it could be pretty fast, but expensive as hell to fix..

I used to have a 300zx na and I know they do sell some pretty wicked engines that cost alot. The thing with those cars are all they need to do is turn up the boost to the engines limit to make some sick power....tough on the rods though. TT owners annoy me sometimes, always complaining about boost leaks and ecu's not programmed right.

Its going to need some healthy mods, definitely upgraded turbos. You are lighter and making serious power, so unless he has fuel system, upgraded turbos, intercoolers, and tuned well, I doubt one will get ya.

All of my questions are really brought on by him slipping up and saying he'd like to race my car because I'd get crushed. A buddy of mine filled me in. I'm thinking even if he does have a dynosheet (which I haven't seen) of some agressively tuned pull that blew his engine, he still wouldn't be able to beat me in mine. I haven't read too many people able to put down 575 to the road without cracking into the engine...at least not safely.

If it is that strong, I'd like to race him quickly. Because if I wait too long, the engine may have already grenaded.

newgene

Even with all that, is it common for them to put down 575?

Electric

Depends on the size of those upgraded turbos

Blackboosted2

There is a local guy making low 500's in his 300zxTT runs 11.2@124 or so (1.6x 60's) I really don't remember if it's a single, or upgraded twins....but it's NOT stock turbo, another making around 300whp (stock twins) and runs 13.7 - 14.2@107.....lol. Bone stock should be a 14.1@99 or so

It all comes down to can the person drive, or setup their car properly? It looks like it does take a lot of time, research and money to get a serious number from these cars. They are't as easy as modding an LS1, and the cars weigh about what an Fbody weighs!

DemitriHKS

My brother has a 1990 300ZX TT and I have the 350Z. The 300 is really an amazing car. He dyno'd 373 torque and 416 horse on his. The mods were Full exhaust no cats, Stillen ECU reflash, JWT pop chargers, Under drive pulleys, Clutch & Flywheel, 16 psi boost jets (stock turbos). The car really flew, especially from 3rd gear pulls. Between him and I we know these cars pretty well. The only thing that sucks about mods to this car is that they are extremely hard to work on. The whole engine bay is tight as hell to work on and it can be a bitch.


On the bright side. Due to the 350Z being out the price of mods has fallen for some BIG power on these cars. Check this link out to some of the power packs they offer. Find a good TT Z and put one of these on......you'll be golden. Let me know if you have any other questions about the car.

I agree the 300ZX TT was THE best Z car ever made. I owned a 1989 300ZX and a 1990 300ZX Twin Turbo from 1998-2002. All I had on it was an HKS intake and HKS CB. It was about like a stock LT1. They weigh about the same as a 4th gen.

newgene

Cool link. Sounds very possible to be in the 500+ rwhp range.

Bone stock they run around 13.8 at 103MPH. People have ran LOW 11s on the stock turbos with around 420RWHP and drag radials. With nitrous people have gone 10s on the stock turbos. With upgraded turbos/injectors/intercoolers he could be anywhere, the stock engine has been taken to 700RWHP so he dosnt need a rebuild to make monster power. Most 300ZX TTs you see on the road are stage III (Intake,exhaust,ecu+boost) which puts them around 400 crank HP and mid 12 second 1/4s. The closest comparison is the MKIV Supra, the main difference being the Supra can make more power on the stock turbos/injectors (500HP vs. 450HP) Check around www.twinturbo.net for more information, there are full interior street Zs in the 9s.

SummerOnTheChain

500 RWHP is attainable on the stock block, 600 is as well but not reliably. Either way he will probably need race gas and turbos of the ball bearing sort.

Here is a quick list of basic mods need for 500 at the wheels.

GT28R or similar Ball bearing turbos
Upgraded intercoolers (Z1, stillen, Ash)
ECU tune
Boost controller
Upgraded injectors (probably 780cc)
Plus a few more supporting mods.


Top end is where the cars shine as they are tricky to launch and really aren't meant for drag racing.

Any other questions feel free to PM me.

RedBeauty84ZX

There are quite a few people over 600RWHP on the stock block without any issues, 2 or 3 people have broke 700RWHP on the stock bottom end.

DemitriHKS

True....its known for having one of the strongest bottom ends ever.

I always saw the Z32 as the lost child. It was over shadowed by the Supra but now they are a great buy for your money and can be Supra killers. I think I may buy one again down the road. The 350Z is fun but it def. needs a turbo setup of some sort to be real fun!

Sparetire

The shop he speaks of might be Jim Wolf Tuning. Probably the best 300Z shop in the US. They are more than capable of making a 500+ WHP Z for 16K.

Question is, did they?

If you both had 500WHP, you will walk him. You would both have similar power under the curve. He would have more aggresive gearing (most likely) but a few hundred pounds more than a C5. Aero would be a wash. You have the traction advantage from a dig.

SummerOnTheChain

Yes I know. But that is not the norm as the cars are 16 or so years old and are racking up the miles. Not saying it can't be done but that is really pushing it.
