are you talking about the purge kit or a direct port?

I am assuming the TT Supras do not suffer the same lag problems

Ahh. I didn't know that the VQ35DE was open deck! That sucks! If only it was closed deck....mmmmm

Can you explain the difference performance wise?

I think it IS a big deal for most people. People are always talking about stock internals....I for one could not justify the engine work ABOVE the cost for the turbos.

BTW..the engine is open deck AND aluminum....I will probably be boosting 8psi MAX. But HA! Thatll be good for like 70hp, and then have the amuse system, CAI, ECU, underdrives... were talking 400 flywheel here. YUMMY!

Just for reference. I had a Greddy 18G kit on my Civic, which had higher compression than our 350Z engine, and was also an open deck engine. I was able to add about 100whp on a conservative tune @ 10psi on a single 18G. So, I would think that 2 18G's (or similarly sized turbos) at 7-8 psi would definitely put the Z close to 400rwhp. As long as it is getting enough fuel, and we have a way to control the timing, there should not be any problems. I just hope the rest of the car can hold the power.

Major Price difference. Single Turbo Supras go up to 600- 700hp, which I've personally seen myself.
Actually the fastest Supras in the world are single turbo.

I've always thought that an auto TT Supras would have to be the major powerhouse. But, a single turbo Supra is no slouch either and I agree.

I think you will find it similar to the Maxima, 7 psi without a I/C max, and 10-11 with an intercooler. Obviously fuel and timing are an issue. I would hope that whoever comes out with a kit will address those issues. I do not think you will need sleeves at 11 psi, and if you are going to go through the trouble to add sleeves, then you might as well add lower comp. piston and new rods.

I personally will stay in the 10psi range with a big FMIC....

I would also want to stay in the 10psi range. But I want to add a Venom N20 kit, would this be a good idea?

Their are numerous Maxima VQ30's running in the 10-11psi with out an intercooler using SC kits that have not had any internal engine issues. I run 13.5 with out an intercooler, I pull ~1 degree of timing per psi of boost starting at ~10psi using a J&S Ultra Safeguard, I never see knock on my J&S knock monitor with it set like that. With an intercooler the timing retard may not be necessary, but for $600 the J&S Ultra Safeguard is allot cheeper than an intercooler and will save the motor if the knock where to get out of control by using the knock sensor readings to retard timing. The Maxima factory timing is VERY conservative, I bet the 350Z is MUCH more agressive. On a turbo I'd say ineter cooler for sure though

this sounds like good news.

To the the guy ranting about "do it right or dont do it all", I think you missed what I was saying. I said most people would like to go the turbo route with stock internals. The whole conversation that I was responding to was "how much without opening the engine?" I want to see how much....I dont care that putting sleeves in will allow 18psi of boost or whatever, that wasnt the point.

PE labels it as a TT set up, but the Turbos are not seqential. There is one turbo per bank. So it is kinda like a single turbo set up. They probably used a turbo that isn't to large so it will spool quiker, but since there is two it should make decent power. F'n cool look'n set up.
That is correct, two small turbos should spool up nicely especially with 3.5 liters of displacement and nice high compression. The open deck block is NOT a problem on this car any more than it is on most other cars. Many factory turbo cars use open deck blocks including the WRX which can support over 400 HP on a daily basis at 20 PSI. It's usually the pistons that fail first when trying to turbo a car that was not factory turbo to begin with. This car has the advantage that is is a V6 which eventually will be the basis for the new GTR motor. It should be very strong like most Nissan motors and should be able to handle 400 HP with ease. Remember, the non-tubo Supra motor can handle 500 HP with ease stock, open block and all. I say you folks are worrying way too much.

Neither one is more reliable than the other. You just have to do it right. If you want reliability, then you probably shouldn't go FI.
