There's only a few here that's done it. Mostly used by drag racers who don't have time to post photos or details except for racetech but his 1200 has the engine set back, totally non-stock

SSS or Mazworkx has everything needed to fit SR20VET into a 1200. You don't need the small-format VVL solenoid, you can cut a hole in the firewall and recess it.

Racetech

Been a while since I've been on here and have searched hi and low but can't really find any info on a sr20 Vet conversion into the 1200
Just wondering if anyone has done it and what mods did you need to do to the end bay ( fire wall, etc ) to make it fit due to the solenoid on the rear of the head. It already purchased a taarks solenoid relocation kit for it but I'm still thinking it's going to be a super tight fit.
For the gearbox I have a built c4 already for it and will be getting fed with a hks t51r Spl as I don't like to do things by halves Hehehehe.

Anyway your Input would be greatly appreciated

Thanks Mick
