Has anyone got experience of swapping the GTT's stock engine for the GTR - both R34? I am considering the upgrade at the moment and wondering if it is worth the cost. Actually the problem I am trying to solve is the gearbox performance on the GTT - a stock auto. After some tuning to around 280 hp I am getting trouble from the gearbox.
Not pretty.
Maybe the gearbox needs an overhaul, but I would prefer to swap it for a manual, of course. But the manual I have sourced is currently attached to the back of an RB26DETT and the suggestion was made to take the engine too and "drop it in". I want to tune the GTT further, so need to plan for more hp.
Option 1. - overhaul the autobox (once fixed, is it capable of handling 300+ hp?)
Option 2. - find a GTT manual gearbox (but can't trace at the moment)
Option 3. - Put in the GTR gearbox I have at the moment (any known problems, issues?)
Option 4. - Put in GTR gearbox and engine, get more power, better tuning platform, 6-speed gearbox, etc
Option 4 seems to be it :-) Seriously, though, this is going to cost $$$. What should engine + box from a half-cut cost?
Anybody see the obvious solution hiding in there as it isn't clear to me!
Thanks
- A/T light comes on after spirited driving. Clears when engine stopped and restarted,
- stuck in third when trying to push past 140kph,
- revs dropping to tick over speed despite car doing 100kph when releasing throttle in D,
- revs soaring when accelerating hard in 2nd (say) but car remains at steady speed.
- slow, delayed changes up when accelerating hard, causing engine to red-line and complain loudly
- etc etc.
