RB25DET Conversion

[AZAgts25t]

Can any one help me with doing a conversion to a R33 GTS25DET engine from a R32 GTS25, i want to know how much it will cost for the engine, doing the wiring loom, new comp, intercooler, etc.... all that has to be done to get it road legal but with a 25t in my R32

Cheers AZA,

Talk to doxximus on this forum, he's converted his.

Hey mate, why don't you just buy mine. Its an R32 with an RB25DET conversion! Anyway, the engine itself in good nick should only be around $2500-3000 with the loom n ecu. You will save yourself heaps if you do the installation urself with some mechanic mates as the labour is the real killer when it comes to overall cost. The previous owner of my car did this (He was 1st aussie owner of the car) which I had professionally inspected and everything was mechanically sound. Once all in, you will need an engineer's certificate to approve the mods cause you've increased the capacity of the engine, & any other mods, etc. Good luck - Hope this helps.

here's a rough breakdown of my costs for stuff from japan, i've got an RB20DE in my 32 GTS...

RB25DET engine - $1500 from a Series 1 R33 with wiring loom

Power FC + hand Controller + EBC usually goes for $1300 from supplier (i got a secondhand one for $900)

HKS Intercooler - $800

TD06 + manifold + wastegate + AFM - $1500

Shipping it all in a container roughly $400, haven't done it yet, will be leaving on the 20th

Putting it all together... hehe doin it all myself with a few mates.

Although if you're goin for stock gear it should be at least $3000 cheaper.

Mind you these are all AUD and also i pulled a few strings.

Putting in an R33 engine with a stock R33 ECU is a pain in the ass apparently because the sensor readings are all different on an R32.

I;ve got wiring diagrams for both cars so if you want em let me know.

hey yeah funky monkey would i be able to have the R32 and R33 wirring loom, as my mate has converted his car engine but he cant do the wirring loom so he has sent it away to be done and they can not do it either, so he is trying to track them down so he can do it.

He has converted a R32 gts to a R33 gts25 (yeah i know why not a gts25t, well thats because he is south african and we can not understand the shit he does sometimes)

funky monkey, you forgot the cost of the tranny

[funkymonkey]

huh? that was a breakdown of my costs, I kept my 5 gear manual transmission from the 32.

Gimme a couple of days to get the manuals back n I'll scan em for ya.

[Jolinator]

oh fair enough

will the 32 box hold the power tho?

i was under the impression its a fair bit weaker than the 25 box?

[AZAgts25t]

yeah the gear box and dif out of a r32 gts25 will hold and also a gts-t gear box and diff will hold however the gts-t gear wont last as long as the gts25 gear box, then it all depends on how much boost you run and how you treat your baby. gts25 gear is around 2500 and a gts-t is around about 1300 dollars so the other alternative is to run a weaker clutch so if that gives you wont have to fork out as much money on the gear box......... the gear boxes in the gts 25 are the same as the gts25t andyway.....................

[funkymonkey]

I don't plan on running high boost all the time, only when I'm on the track. Other times the car's used as a daily driver so I doubt the gearbox will get a thrashing.

The box will only give if I drive it like a d!ck and race everyone I see at a traffic light. I'm not into that shit anymore so I'm sure the gearbox will last a lil while, might have to change the clutch. I'll replace the parts as they give, coz the resale value of an R32 gearbox is pityful.

[AZAgts25t]

funky monkey yeah nah i was meaning to respond to um..... jolinator but yeah thats true if u dont thrash it then u wont have to fix it

its as simple as that aye...
