Workshop For Engine Conversion In Brisbane

[Skyrin3]

Hi Guys,

Ive been reading about people doing their own conversions of RB25 or RB26 into a R32 GTST. Im not sure what to go for, a 25 or 26. Im not chasing HUGE numbers around 220rwkw would be fine so a 25 would be a good choice.

From my research it appears i need the following,

RB25 Engine and Loom

RB25 Gearbox

Diff??? (Not sure)

Heavy Duty Clutch (A want item)

Where would be the best place to have this done, I know its a DIY job but im not very confident in doing it myself. Any information or help would be great.

Thanks

[PWND]

had mine done jan

diff you don't need to change. heavy duty clutch, maybe. depends on what you get with the engine and gearbox you purchase. you may get lucky and already have one fitted in there.

you will need to modify your tailshaft. I had a custom one made up for $550, but you can modify your original one.

apart from that, can't really recall needing anything else.

^^^Go see Mick at Signature ^^^

They've had so many Skylines apart & back together lately the hand-tools could almost do the job on their own

[Lazy-Bastard]

Are you calling me a tool?

[Skyrin3]

Ok will call signature.

Based on me having the engine and gearbox already what figure (ballpark) would i be looking at to have old engine+box pulled and 25-26 + box fitted.

Also what price would I be able to sell my RB20 and box for it has 90,000kms

If you can get the box and motor out yourself go see Murnane Motors on the coast they charge $5000 to sit a RB26 between the strut towers and weld up the front diff for RWD and make a dump pipe - in a R32 GTST.

Dont expect anything to be hooked up you are expected to either pay them more money or take it somewhere else if you want the car running...

If that does not sound enticing go see Mick @ Signature or wait till Dan (Elite Racing) slows down a bit, I believe he is into that sort of thing...

Few options there for you, Every performance workshop can do the simple RB Engine conversions

Just be careful because service/price/customer satisfaction differs greatly depending where you go

[PWND]

5k? jesus. do they provide the rb26?

[dano4127]

you would think so but no.

[Skyrin3]

I have about $5500 to get the engine + box, I guess a RB26 is out BUT a 25 will do nicely. What the hell im going to have a crack at it myself.

I will do pics ect as it progresses.

NOW for a question, Who can i go see to Connect everything up and make me a custom tail shaft

SMP Performance Phone 3208 1644 down near Moss street

Dan Elite but i know he is super busy

or if Ipswich is not too far Signature Performance

220rwkw?

for the $5K you have to spend, you could make a reliable 250rwkw out of the RB20.

without the hassles of rego paper work, engine swap, being off the road for ages etc.

to make 220rwkw out of an RB25 you are going to need upgraded....

intercooler, fuel pump, afm, injectors, turbo, exhaust, ecu, tune

now, if you buy the above parts for the RB20 you already have, you will still make over 220rwkw and not have to fork out for the purchase of RB25, gearbox, tailshaft, engine swap costs.

If your goal was on the crazy side of 250rwkw, i'd understand the need for more capacity.

just a thought mate.

I think spending the cash on the rb20 will yeald good results for less money.

have a look in to the RB20 dyno results thread in the forced induction section to see what mods make what power on peoples cars.

Yeah i have have been looking at the dyno results for RB20s with upgraded bits. What im unsure about is the torque low down. Everyone is saying how much more power the RB25 makes over a 20, I had a 33 GTST with a bit of work done it was decent. But if a RB20 will make the power im chasing maybe thats the best way to go.

Will i still need a 33 box to handle the power>??

[dano4127]

220 should be fine mate just drive it if it eventually lets go put in a 25 one...

[TTT]

need for gearbox depends on driving style.

see the car in the vid in my signature.

260rwkw

stock rb20 block and head.

td06 20g (8cm)

ecu blah blah blah.

8800rpm

22 psi (I think)

stock rb20 gearbox

The details of his motor is in that rb20 dyno thread somewhere.

it's Roy's car.

Edit - here is his post

NOW for a question, Who can i go see to Connect everything up and make me a custom tail shaft

Depending when you plan to do the conversion, I can offer to do a plug'n'play loom for you. Send me the RB20 and Rb25 looms and I will return it ready to simply plug in and go. I wire up all items to ensure complete functionality of the standard RB25 ECU (eg. boost solenoid, VCT, FICD, A/C etc). I normally charge $300 for a series 1 or 2 RB25 or RB26.

I have personally done the RB25 into R32 conversion twice and can recommend it. The RB25 gearbox will require more work and if you already have a manual R32 you will need to either modify the gearbox crossmember or make a new one. If the car was originally auto and you plan to use the RB25 gearbox, from what I have seen the original crossmember should bolt up ok.

Cheers
