Am I the only one who thinks this car is too heavy?

The weight is right for the engine potential. That is one of the reasons I chose an 85 to build.

It may be "off" from the process, but probably not by much. I think it is the highest stock hp car (200 right?) in IT. So, barring other factors, it should have the highest weight.

It is rated 200 hp stock. The way I figure it it should be about 150 lbs lighter than it is.

Inline 6's were processed with a 30% multiplier when I was on the AC. Take a look at everything in the ITCS with that style motor and work back from IT-prep power. All VERY potent.

200*1.3*11.25=2925

Huh? It's an ITR car and it is far from the highest HP. Actually a pretty decent weight for a car with power and torque.

No, it is in ITS (highest stock hp again, in S), at like 3200 something.

Weird. 2 Supras in ITR. The 220hp 93-97 and the 87-92 which has 200hp. 200hp in ITR is exactly 2925lbs.

Check out the overlap of years in the ITCS...86-87

A fix is in order I guess...

Was there an early and a late addition 87? The car I drove would likely struggle to get to 2925, but could shed 150-200 lbs I am sure. I don't deny that the car makes power, it does. However the weight ruins it under braking and hinders it around corners. Hard to get it within 4 seconds of the front running ITS times at Mid-O.

Yes, needs a clean up. I think the intent was to leave the early one in ITS. There are actually a number of these cars out there running.

What say the Supra drivers? S or R?

Car needs to stay in ITS. We used it this last weekend at the 13hr. Can't keep up with ITR cars on straights. Not enough weight to take out. We were actually winning ITS until the engine blew up on me with 10 mins left in the race. Sorry to anyone who got caught up in my oil....:o

Being an ex-Supra driver (The 85 race car, the parts car and an almost ready to get inspected street car were all lost in the Great Bastrop Labor Day Conflagration of 2011) I of the opinion the 3rd gens need to by in S at about 3100#s. The second gens are pretty close to correct weight.

The ITS Second gen Supra, the 240Z and the RX7 are all quite close as is.

How do these cars handle ?

I have a buddy that is thinking about building an 84 Celica ( with 6 cyl transplant ) for Chump

Any tips in regard to the build ?

What are the weak points ?

don't know if it matters but there was a fairly clean and reliable ITR supra for sale at the Turkey trots down at sebring this weekend. Looked reliable.. the guy raced it, parked it with a for sale sign, never touched it, got back in the car to race it again, then parked it by the road in the paddock to try to sell it again.

Taking out the air conditioning and all of its components would definately help your chubby girl lose some weight...there's a way of replacing the doors with some light weight material like carbon fiber or something. also the back window can be replaced with some light weight plastic..this is some serious weight loss :)

Read the rule book. We know how to lighten the car. The problem is doing it legally.
