hey guys, i was thinkin about buying 2 turbo's off a TT engine, but my car is NA and im wondering if you guys know where i can buy some down pipes and i was also wondering how much boost the NA engine can handle. Im hoping to get about a 50hp gain from each turbo, and kinda hoping to do it without having to build the intercooler setup. basically im just wondering what parts im gonna need, where i can get um, and how much boost that engine can safley handle.

Without IC's your engine well blow up trying to gain 100hp on a NA engine. If you do try this setup all of your hard work and money is wasted. BTW what kind of ECU are you going to run? You won't be able to run a NA or TT ECU because of your setup and if you going custome your going to pay some bucks, just a thought.
Since you seem to have a limited budget look on ebay for your DP's.

I thought the NA and TT engines were pretty much the same except for the slightly higher compression on the NA. He should be able to hit 300 Hp at a lower psi than the TTs require. But I otherwise agree, I'm sure a new ECU and other things will be required. It's a subject that's been rehashed a thousand times, and the general answer is that it was probably better to buy a TT in the first place.

Oops!! I made a type O. What I mean't to say is " without IC's your Z will blow up. :dumbass:
The difference in engine is that the oil passages are different, plug, unplug, and check valves in the block, oil squirters point in different directions, oil pump is dif., oil filter bracket is different, TT also has a oil cooler, Exhaust valves are made of different materials, rod bearing are made of different materials, heads are different, and TB's are different on pass. side. That is all that comes to mind for now.
ok so far you guys have been a big help, this is what im thinkin, i could buy some turbo's off a TT and buy some downpipes and test pipes of ebay. Then ill mount up a intercooler and see how that works. It should only cost me around 500 bucks and i figure if i set the boost @ a low enough psi so i dont blow my engine up i should b able to get a 75hp + gain. But this ECU stuff is kinda throwing me off, Why do i need a new ECU? i havent heard of getting new ecu's for turbo addons, but is it because the airflow to the engine is gonna be really different so the car will run real weird or somehing? can someone plz explain that part to me?
You always have to modify your ECU for it to run right (most of the time). Some ECU's can compensate a little but not enough. For you it would be better to just buy a VG30DETT or get access to one and it's ECU and rip everything off of it.

A NA ecu has a different fuel and Ign. map. TT's have bigger injectors.
well i know that the 2 ecus are different and all but, say on my last car (95 eclipse gs) if i were to get a turbo, after i got it on, you dont buy i different ecu. Im not sure how the eclipse makes up for having the forced induction but i know you dont get a differnt ecu.. How would the 300zx run if i didnt get a different ecu?

oh yea i totally agree with you on that, im not looking to try and make it faster that a stock TT im just trying to make it faster than a stock NA. I dont have enough money for a engine swap right now and i dont know if i ever will, so i was just thinkin this might be a fun way to boost some HP for low amounts of money. Does anyone know how much boost the engine internals, like piston rings and stuff can handle? i know my eclipse could have taken like 12psi or something but i would imagine this engine is much stronger than a crapy old 420a.

Typical average boost pressure most NA engines can take with no internal mods is 6 to 8 psi. I don't think the 420A can take 12 psi, I know a lotta guys in the DSM business and the general consensus is that the 420A is made out of glass...... Like I said, 6-8 psi is right about where you want to be and not compromise reliability. Pretty sure you'll still need an upgraded ECU and a few other things.

yea i could be wrong with the 12psi, i just thought thats what i had heard, so i can put 6-8psi on each turbo? Anyone know of any good companies that sell turbo kits for 300zx? maby i could call them and ask the indepth questions.
having 2 turbos at 6-8 PSI doesn't give you 12 or 16 PSI. You want to set them both at 6-8 PSI (Which isn't that the stock boost?) you might not have to set anything.

Using the stock turbo set off of a TT would probably be your cheapest bet.
