Hi, I own a R33 GTR. The car is modded with a JUN ECU;Trust Profec B Boost Controller;OS Giken twin plate clutch;HKS air filter,Super Drager,hiper damper (with Eibach springs)and iridium plugs and a Trust oil cooler. NISMO 3 piece magnesium 18" rims are used with Bridgestone S-02 265/35/18 tyres.
Recent dyno posted approximately 311.7bhp and 34 kg torque on stock boost (0.75 kg); 352.3 bhp and 40 kg torque at 0.95 kg boost and 380.3 bhp and 44.1 kg torque at 1.12 kg boost. All readings are from the tyres. ( I wonder what the readings will be at the engine).
I am told by my mechanic that it is rather risky to run the car at 1.12 boost without modding the engine. Is this true? If so, can anybody tell me what it takes to run the car continuoslyt at 1.12 or even 1.2. I am thinking of changinh the cam,valve springs,piston and pulleys. Would that help? Future mods plan include installing HKS intercooler (can anybody suggest better intercooler or water spray for the intercooler).
The car is fast, even at stock boost. Handling is simply superb. Hard cornering feels very safe after the hiper damper was installed. The Eibach springs are however quite hard for normal roads resulting in bumpy rides on terrible roads. (my wife just hates this!). But on track ( I go to the Malaysian Sepang F1 track), the car is simply breathtaking!Floor the hammer on the unique twin straights and the car just flies to about 260kmh on 0.95 boost. Full braking, clutch the monster, down shift to 2nd at the S corner after the Start line - and you would know why the GTR is such a great car.
I sometime drive it to work. No problem at all. Will do 40-60 kmh on 4th or 5th. Parking - side or reverse - is easy. The clutch could be a bit tiring in long traffic jams though. Release it early and the car would stall!!
I thoroughly love the car. I could send a picture to this forum but I don't know how! (being computerphobic does not help!).
Enough bragging. Ciao!!
