Get me a job where you work, and I’ll help you do this.
Seriously though, it is quite impossible. You’re better off buying an R32 and doing this conversion if your serious. Buy a GTS-4 and swap an Rb26 in. Direct drop in.
You’ll end up spending less time, effort and money. And also will start with a much cleaner platform, and one meant for the RB series motor.
They make R32.4 front end kits. I’ve seen the rear been done before, it doesn’t look as great as you may think.
P.s- I predict this thread being bashed to all hell.
