R33 or R32 GTS-T???

Most fit RB26 bottomend inside RB25DET shortblock (stock RB26 crank, stock I beam conrods or H beam conrod, forged pistons, etc) to lower compression with RB25DET engine.

Make sure you have gearbox oilcooler if using car on racetrack, not enough air around RB25DET gearbox to cool it with R32 tunnel.

R32 GTR differential (subframe, brakes, etc), as stock R32 GTS-T halfshaft's, etc are not strong enough. You'll need R32 GTR rear shocks (rear springs to match rwd car, not 4wd car), as bottom mounts on GTR rear shocks are U instead of O on GTS.

With R32 GTS-T, would be easier to buy a R32 GTR, as most parts you have to replace a R32 GTR has as stock equipment. Or use a crashed R32 GTR as a donor car for parts and make it rwd (cut off transfer case, weld plate over hole, etc).

If R33 with RB25DET, R33 RB26 conversion (RB26 block can fit 2x different sumps, 2wd, 4wd but best to modify stock 4wd RB26 sump). It should plug in under dash on R33 if have R33 GTR loom (same plugs). By the time you mod the RB25DET engine, you would have converted it into a RB26. So start with a RB26 engine that has higher potential.

Also you'll need a Link ECU or ViPEC ECU, etc with those mods (not cheap).
