A full proper conversion will consist of:
- RB25DET
- Turbo
- Turbo Dump pipe with front pipe for it (cannot confirm if the same with NA)
- ECU
- Possibly engine Loom
- Tripple Gauge Cluster
- Drive shaft (been told it's bigger)
- Rear Diff
- Rear hubs (NA have eyelet type shock mounting points, GTT's have a fork type. This may probably not be that necessary)
- R34 GTT Suspension (or at least the rear fork shocks, again possibly not necessary)
- GTT Calipers & Disc
- BM50 Brake Master Cylinder
- Possibly a brake booster
- Intercooler
- Larger Exhaust (not sure if necessary but I'm quite certain it's just for added performance)
Thing's you need to do:
- Swap parts over
- Use circular saw to saw a hole for intercooler (I can give you reference points where to saw)
I may have left a few small things out but this is coming from myself owning a NA 34, while wrecking a 34 GTT (wrecked two). If you need parts, I can supply the following:
- RB25DET - YES
- Turbo - YES
- Turbo Dump pipe with front pipe for it (cannot confirm if the same with NA) - YES
- ECU - YES
- Possibly engine Loom - YES
- Tripple Gauge Cluster - YES, Cluster only, no cover
- Dash with Tripple gauge cluster cut out - YES
- Drive shaft (been told it's bigger) - YES (off a Sedan, unsure if same or not, though I have a manual GTT coupe, probably works)
- Rear Diff - YES
- Rear hubs - YES
- R34 GTT Suspension - NO
- GTT Calipers & Disc - YES
- BM50 Brake Master Cylinder - YES
- Possibly a brake booster - YES
- Intercooler - NO
- Larger Exhaust (not sure if necessary but I'm quite certain it's just for added performance) - YES
A/T Gearbox - YES (if you need)
I think the dash loom could possibly be a little different to accommodate the triple gauge cluster, I have that too and can throw in if you grab em off me. PM me if you have questions
