I don't plan to run that much power on the track but heat will be a issue and I'm working on several mods to help add this. Then ill go from there. I ultimatly plan to have a Time Attack car so heat issues won't be all that much of an issue. Ill just have to see where my car takes me.

Are you talking about the white Nismo that FP built, fully caged, gutted, etc?

That's correct, Jay.

Shamu, I'm not going to be running a built motor yet. Something happens, it happens. Ill be ready. But these cars can handle a lot FI on lower boost settings. It's the heat ill have to see about.

VQ can handle low amounts of boost in street and ax situations. I haven't seen a single boosted VQ engine last on track. You're probably looking very limited motor life without forged internals and major cooling efforts. Why not prepare yourself now rather than face inevitable later in the season? There's a reason I'm not running blown motor anymore. Wasn't willing to spend money on rebuild yet. Oh well you will have some short term fun! I guess you could just replace motor with used one from junk yard. To build proper FI track motor you're looking at $20 k easy. That's why I'm saving my pennies for GTR motor that will run stock or even less boost. I will be interested in how long a stock motor lasts on track with turbo though its a cool experiment. Bets? I say 6 track days.

You need RFS and fuel regulator with most any boosted application. Marketing from companies selling turbos and non RFS fueling systems will tell you otherwise but don't believe them. Stock non return system isn't designed for any level of tuning in my opinion. You will always be compromised without return and a proper regulator.

Can you share what mods you're planning to do for cooling?

I would like to hear from track drivers

I thought they got it more under control when they added more oil reserve to the system and modified the front bumper?

Jay was a good guy!

his oil cooler was the size of our damn radiators!

I think they may have. It was a NASCAR style oil cooler.

Mine literally is the size of my radiator... almost.

It's like 28" x 14" but only a half inch thick.

With the motor pulled I'm shaving the first fire wall in hope it won't trap heat and allow the heat to flow out the vented hood and cowl area. On top of some more ducting, GTM's bigger oil pan, and my 34R cooler. Ill add another if I have to.

theDreamer · 06-04-2013, 11:34 AM

Have you thought about doing the vented fender liners on each side, so the air will flow on the edges of your stillen front straight through and out.

SPOHN · 06-04-2013, 11:37 AM

I have a lot of plans in that area just time and money is always a issue. Defiantly custom.

Reaper42 · 06-04-2013, 12:34 PM

I dont understand why your going FI either on such a dedicated track car. Even if you plan on not producing crazy 450-500 hp and more like 400 something in order to save engine and keep temps down...isnt it the added weight of a tt kit negate a +50 hp bump? Thats what I was always worried with going FI, heat issues, and the obvious power to weight ratio. Adding 100hp with doing a tt kit on a na car isnt the same as adding 100hp to an already boosted car since the naturally FI vehicle already had the weight on it and in some instances you're actually using lighter than stock replacement parts.

theDreamer · 06-04-2013, 12:44 PM

It is not always about the top end HP, you have to look at the new power curve and when you have usable power, great TQ levels, but you do have to weight the weight side (especially since it is all front).

SPOHN · 06-04-2013, 12:52 PM

Like the engineers of the GTR said one time on TV. Anyone that thinks power to weight is a issue than there amateurs. Lol. Why do you think the GTR is a beast? On paper the HP/ weight ratio shouldn't do what it does.

But yea. It's the way power is deliveried threw the ban. I was getting my butt handed to me by Porches that had the same power as I did.

True but thats because GTR has A LOT more engineering behind every single little component of it. So that doesnt really apply to a 370z that has NONE of that suspension, torque vectoring diffs, AWD, super computing, etc technology. But like Shamu said I think the best way of doing a TT 370 would be to swap in the gtr powertrain. A set up that came that way from factory and will be consistantly reliable.

I ran with a 500whp stillen supercharged 370z at the track 2 weeks ago. Thing couldnt pull on me in the straights.

Allthough, if you can pull this off and the car runs great, I will be VERY impressed with ya. Your car is already one of the top 3 impressive 370s I have ever seen. Good luck!
