I want to duplicate Rob Fuller's '71 510 SR20DET(S13) in Go Green.
There are 2 hurdles I need to get over for this build, based on the 1/25 Revell Tuner kit:
1) Sourcing/detailing the SR20 Motor and turbo/IC piping
2) Fitting front wheels/tires
Another problem is that Rob's car doesn't have the bubble flares, and it's not within my ability to form stock fenders so oh well
This car is also in the June '04 isue of SportCompactCar. I'll update with better pics when I visit the shop.

I'm using Tamiya Light Green for the body.

I stole the S15 SR20DET top end from a 1/24 die-cast Silvia and mated it with the L16 bottom end from the REvell kit. It looks rough right now.

I'll use this exhaust manifold and somehow create a bottom mount turbo. Any ideas on how to make one?

This is the GReddy oil pan.

I flipped the crossmember(like on the 1:1) and I'll use the BRE oil pan to mimic the Greddy one.

Good thing about this kit is that it accepts larger than stock wheels in back, so no inner well cutting! The front is a different story. If you want to lower it the inner fender gets in the way and it looks quite lame. I'm working on that.

If I can open up the grille maybe a front mount IC will work.
It will be a tight fit with the IC piping and wiring, but I like the challenge!!
