Having had a TT race car on road coarces for a few years you will find a few interesting problems - some good /some bad. We had a engine for the race car done by one of the best motor builders for the factory Nissan and Honda cars ( got to love sponsorship money) We had a tom of power. But enven in full race trim, the cars with smaller motors and a lot less weight would kill us in the corners. Lord knows we know how to set up suspensions as well. So we opted for a Mitsu (first gen) AWD turbo with about 200 less H/P and are running 2 seconds on average faster at each track. Clearly the AWD is a major factor. In my old driving days - when I was still drving cometitiely I owned a 76 930 Turbo. The major provblem besides expense for repairs is a Porsche loves oversteer. It takes a whole new level of driving to mater them at speed. As for set-ups for road racing on a Z - Here is what we had on ours: 1999 Specifications 1990 300ZX Twin Turbo JWT Sport 500 Turbos (re-built by John Meyers Racing) Stillen 485cc fuel injectors Stillen Intercoolers Stillen ECU and boost jets Sunbelt Racing "Race Chip" Sunbelt Racing Engine Z32 block, bored & polished (50mm) over 10:1 compression ratio Ceramic coated JWT pistons (over sized) 5 angle valve job on heads Ported and polished intake runners ARP rod bolts Performance springs Cam timing to race specs Fully balanced and blueprinted (dyno tested on bench) Twin Stillen high flow intake Stillen high capacity oil cooler Stillen lower radiator hose Centerforce Kevlar extreme duty clutch Sequential BOV 3" straight pipes (no cats) NGK Racing Plugs Red Line Synthetic HKS Turbo Timer HKS boost gauge / Exhaust Temp Gauge / Oil Pressure Gauge Eibach Pro Kit Springs Tokico 5 way Adjustable Shocks Stillen Sway bars (28mm front - 21mm rear) Stillen Adjustable Upper A Arms Stillen Adjustable Tension Rods Stillen (Goodridge) stainless steel brake lines Skyline front rotors and calipers Stillen Sport Rotors (rear) Hawk "Blue" brake pads 3"x5" NACA ducts & neoprene tubes to front calipers 17" OZ two piece Racing wheels BFG R1 Racing tires (shaved) 245-45-17 front 285-45-17 rear Stillen GTZ Rear Wing SMZ front spoiler SMZ side skirts SMZ Louvered Panel (functional) MOMO "T" Frame racing seat (16 LBS) simpson 5 Point Racing Harness 6 Point Roll Cage (J&P Chassis works) : I am planning to set up a track car for myself for performance driving schools. I am currently torn between the TT and setting up an older 911. I currently have a 90 TT with stage III. : If I set up my TT: : - how much more upgrades would I need? : - brakes - Skyline vs. Brembo vs. AP - what would I need? : - I think the TT weighs about 3300 lbs - how light can I make this car if I gutted it, and added carbon fiber or race panels? What is the best source for these parts? : - Suspension - I will be updating to Tokico 5-ways, Eibach springs; and polyurethane bushings - any other considerations? : - Power - I am upgrading to HKS intercoolers. What else should I consider? : - Drive line - any tranny, driveshaft or rear diff upgrades suggested? : - Wheels and tires - What is the largest size rears I can use without body modification? : Any considerations if I wanted to set up a 911? :
