Rb25 Or Rb26 Convertion To A R32gtst

[iandawsonwa]

hay i got 92 r32 with a rb20 which has a few problems that are realy gettin on my nervs . So i was wonder if how mush it would caost just to put a new and bigger motor in and how mush will it cost and whats the best place to get it done in perth. I know i will probly need to get a rb25 box but what is easyer i to put in to a r32 a rb26dett or a rb25det neo if possable. i do have over 10 gand saved will this be enuf.

or should i just keep trying to fix the rb20det and turn it ino a hurter.

25 is easyer but the 26 is still easy

Ring us 2moro and i can quote you.94588155.

if you dont mind could u let me know what it amounted to! iv been saving to do this for a wile now!

[APA]

why is everyone spelling easier..... as easyer? Lol

10k should cover most items

a gt-r cut will set you back about 6-7 grand most likely

you can sell the gt-r box off for about a grand, a rb25 box will cost 12-1500 with a cross member etc

essentially its a drop in operation, you will need to modify the rb26 sump to clear the cross memeber in the gts-t as it has the diff built in, which can be removed..

ecu etc, you can stick with the stock rb26 ecu, the loom etc should plug into the r32 loom with very little modification, and when its all settled in and you want to play around, you can just rom the factory ecu...

should end up with a little bit of change from your ten k, depending on who you get to do it, if you do it yourself you save more..

10 grand for a 26 yeh denver? Wouldn't be that much for a 25 surely..

complete conversion i mean.

main cost difference is in the front cut

25 cuts are a couple of k cheaper than the 26...

downside to the 25 is the ecu is not romable, but r32 gt-r ecu's are..

big upside to the R cut is it'd come with cooler and associated pipe work <hopefully> so its something extra you wouldn't need to pay up for when doing a 25 convo

otherwise they're much a muchness, big difference being the sump on the 25, unless you end up with a gts-4 cut somehow..

[Josh]

Yeh, thats what I thought - Can you not use a different ECU with the 25 tho? Like a 20?

[iandawsonwa]

rb26 is sounding bit more intresting and i can use some parts from my rb20 like the after market coil packs and a few other things on the rb26. will probly not be able to do this my self though any suggests or recommations on were to get it done. hopefuly mite have enuf theft over for a respay.

[Denver]

you can use a 20 ecu on it, but you need something to actuate the vvt solenoid, which is mainly just an off off switch, but you need to do it at the right rpm, can be done tho..

iand, don't jump the gun on the re-spray just yet, do some ringing around, get some prices etc and work out your budget

a few places i can recomend to you, going north to south

tenagah

hyperdrive

speedworks

c-red

xspeed

they'd be the best places to start and ask a few questions about the costs etc and what they can do, places like hyperdrive, c-red and x-speed can also source cuts, or get in contact with mrmayhem or dsturbed as they too will also be able to source a cut for you

[Josh]

Although it might not be the best thing to do - could you not deactivate VVT? so it doesn't function...

[stR33ter]

you could always go the sr20 mod

cheaper and such

there are a few of those getting around now

fit well in a r32

there is a member here with that mod

<{POST_SNAPBACK}>

You could, you'd loose the performance gain that it gives you tho, so its not something id recomend..

[Josh]

Yeh thats what I expected.

I just did the rb26 conversion into my 32 gts4. Picked up a low k half cut for 4k, with brakes, gearbox, cooler etc. ceramic clutch was 500 and labour to put the motor in 500. After selling the rb20 and box ($2500) the whole thing came out as $2.5k. Can be done cheaply.

wat bout the legalities...

[SKY 34]

the cops can't tell the diff between RB 26 and RB 25~~ I dun think I can either ..well without the engine cover N stuff

[PHATR32]

what about the wiring? the r32 gtst and r32 gtr wiring the same??

usually i find the wiring to be the biggest pain in the ass when doing a conversion.

[RedLine07]

The wiring is a bit different, but doesn't take too long to get it all working.

[iandawsonwa]

probly will not be doing a converstion now have decided to keep the rb20 thanks for the advice though
