For youngtimer racing we can't use a modern injection system because of the Fia regulation. We are allowed to use a GTS replica engine.

Has anybody build that before ?

Deos anyone has pictures of 924 GTS parts ?

Base will be a 931 engine.

- different pistons 8:1
- 1 bar boost
- front mount intercooler
- different turbo (951 250bhp) ?
- costum made intaken manifold
- costum made exhaust manifold
- different injectors ?
- fuel metering head from a 928S
- Different camshaft ?
- ??

If you are building a FIA car, get the homologation documents first! The GTS wasn´t homologated, try either 924turbo Gr.4 or Carrera GT Gr.4. if you want a GTS replica.

A warning, it is going to get expensive and take time. The GTS turbo and intercooler specs are close to 944 turbo. Cams are free in Gr.4. Fueldistributor was adjustable like Ferrarri and Mercedes, not like the castiron unit from 928.
