SC300 as a chumpcar?


Recommended Posts

Hi,

 

Instead of getting a E36 a SC300 might be a cool option. The E36 vs SC300 debate comes up every now and then.

For a SCCA/NASA/HPDE car it might not be the obvious choice. But since it's chump it might make sense.

I know there are some fast ones running in chump.

 

So what are the pros and cons with a SC300 for chump?

 

This is what google has told be so far:

 

Pros:

- Stiff chassi

- Good power (~220hp)

- Reliable engine

- A lot of similarities with the Supra

- Good aero

- 20 gal gas tank

 

Cons:

- No aftermarket parts unless the supra part will fit

- Maybe a tad heavy (Slightly heavier than E36 in race form)

- Front heavy (not sure why?)

- No one tracks them (outside chump)

 

Transmissions, brakes, some suspension parts and engines are supra replacements.

We raced one for a year or so and unfortunately just sold it due to most of our team not being able to race for the foreseeable future. I very much enjoyed wrenching on and racing the car. Here's a few oddball thoughts as they come to mind.

 

Pros:

- Double wishbone all around, great camber adjust-ability = great tire wear and handling

- extremely reliable all around engine, drivetrain, suspension, etc

- can go 2+ hours with the large tank

- long wheelbase makes for very stable handling

- 2jz is non-interference (kind of nice to know in case the timing belt does let go)

- easy brake upgrade with LS400 front calipers

- easy suspension with supra bilstein's all around

 

Cons:

- hard to find a manual for cheap....we paid just over $2k for ours in decent running condition and we thought that was a steal

- open diff as mentioned above

- front lower control arms and rear uppers are very expensive new and do not have a serviceable ball joint so used can be a crap shoot

- large footprint, not the smallest car to make your way through traffic with

- 500 pts as mentioned above, although with so many of the new rules (open ecu, open equal diameter springs, etc) it might be easier to make it competitive

 

We weren't sure why they made the VVT years equal points last year. As far as I can tell I don't see any downsides to buying a 98 or 99 car (except for price).

On the A arm for both the Fox Mustang and the first gen RX-7 there is a ball joint that is said to be non-serviceable in the manual and to just buy a whole new A arm with ball joint complete.  For both vehicles we got just a ball joint  and had the old one removed and the new one pressed in.

I thought that a Supra transmission would fit? Ebay shows some for a few hundred?

Pros:

Pretty much everything.

 

Cons:

Extremely high initial cost. 

Expensive tire size 

Expensive fuel bill 

 

 

Basically - If you have the $$$$ its a great car. If your on a budget, a neon or civic would be much cheaper.

If someone is seriously looking for one my uncle has a nice SC300 that he was going to build before he built his fastback.   It has no interior and already has a 5spd in it.   Very clean car and runs and drives.   PM me for his #.   Car is on the Space Coast in Fl

Did you mean differential? Almost all parts swap directly over from a supra. However the transmission that comes out of the turbo supra is much stronger and much more expensive (look at eBay for r154). The na supra and sc300 share the same w58 transmission and they aren't too crazy expensive.
