Yes heterodyne...im agree. I just finished on GTR conversion on R33 body and now my latest project, to convert rb 25 to e46 body...got 2 project in hand...1 down hehe..btw if you wish to convert from rb25 to rb26, normally the transplant is much easier if you maintain the stock rb25 gearbox. Because, if rb26 gearbox, you have to cut at the gearbox floor to run the 4wd...JPJ wont allowed that! May fail during inspection. If rb 25 gearbox, just plug and play but the crucial part is you have to cut the 4wd lock at oil pan area and this thing will take about 2 days to remove it. Other than that, I don’t think any other crucial part for the conversion. Its hard to find GTR r33 unless if you buy from England. We took almost 1 week to complete the transplant (just to install the engine & wiring)...
ngiing - if you intend to convert as per discussed, this are the things you need to standby etc:
1. R33 gtr is the rare spesis, and hard to find the half cut. Normally Japanese will not cut this model (unless if the car meet an accident) and they directly shipping to Europe especially in England country. The market price for half cut GTR R33 now is around 15-17k..Depends on goodies...
2. I would recommend you to take the R32 Gtr instead of R33…Much easier to get and the cost is around 8-10k..
3. Forget about 4wd, you may use back your old gearbox!
4. make sure you reserve an extra money to replace some parts i.e spark plug, etc.
5. Intercooler & exhaust piping blow off (normally they come stock) and replace all oil seal at the engine parts...
6. 2 bottles of full synthetic oil with an extra normal oil & engine flush (both will be use for engine flush).
Hmm other than that, you may contact me through PM..
