I've been setting up my Z for track use. Got most of my suspension done and interior stuff. My question is that I just bought a TN Single turbo kit and am wondering if there is anything else I need to look into now that I am going FI. I would hate to get out there and blow the thing on my first "blown" track day.

 

Radiator, maybe an oil cooler...

 

I concur with both of those - almost a requirement for FI on the track.

You might want to add some insulation to your clutch line too, and replace that fluid with a high temp fluid. I boiled my clutch fluid on the track due to the heat of my turbos. Adding a Thermotec sleeve and changing to MOTUL RBF600 fluid solved the problem.

 

Thanks for the advice guys. The radiator came to mind before cause I read it somewhere but I hadnt considered the other suggestions.

 

If you are going to put wider wheels and tires on the car, a good power steering cooler could be worth serious consideration too. And a bbk

 

I think if you read his sig, Ed, he mentions a BBK. I agree, such an increase in power demands a BBK. Even without FI, the stock brakes are not up to track use, unless you have the Brembos (and even then, I'm not so sure).

 

You are correct, I should have checked the sig. The brakes thing can be a touchy subject. Our cars are so -o-o-o-o-o heavy!

When I ran the car with a s/c on the 14inch StopTechs and stock motor it was beautiful. Brakes were "bulletproof". When I went to the JWT on a built motor, the speeds were quantumly higher at the end of the big straights, and the additional strain of bringing the beast down another 15mph several times a lap (specifically at Cal Speedway at the end of the Roval, then the hairpin turn 9, and finally the end of the infiled straight) cooked the ST set up. The rears were gone in particular. So, I went to AP Racing and no problems since then, and if anything I have been going considerably faster. So my concern for him is that if he takes it up a notch on the motor, he needs to revisit all of his suspension and braking choices.

 

You're absolutely right, Ed. Brakes are so very important if you go FI in these heavy cars. I'm very glad that I was able to upgrade to the 14" Rotoras. So far, they've been great. I did wear out a set of front pads in a track day and a half at Buttonwillow though (and it wasn't even hot). But they gave me warning that that were going away, so I can't ask for much more than that. I was amazed that the rears were still perfect, more than 50% pad left. Best brakes I have ever had on a street car.

When I had the 13" front Stop Techs and stock rears, they would sometimes overheat if I really pushed hard (and that was when I was N/A). But the stock rears were awful - I would have to bleed them after ever session on the track. But I am pretty hard on brakes. Let's just say I know how to use them to their full potential!

 

I hope my stop tech's hold up. I'm going to run hoses to the calipers for the track. I did this in my Mustang and I could tell the difference. Hopefully it works well this time around.

 

The StopTechs are great equipment. And any piece of equipment will benefit from another that helps it to do its job. Expression of heat is a key consideration in braking, and to help the exchange through ducting is a great thing to do, especially for the rear calipers and rotors which do not have access to as much airflow.

 

Bring extra fuel if the track doesn't have pumps. And I would run 100 octane or more just to be safe.

 

Thanks bro. I've been to Pocono and Lime Rock and neither had fuel so that's a good idea. Never thought of 100 octane though.
