Rb26 In A 32 Gtst

[play r 32]

hey everyone just chasing some feedback from anyone who has succesfully done the rb26 conversion into a r32 gtst.

how mch did you pay?

what sort of power are you putting out?

how driveable is the car being only RWD?

I will be joining the twin turbo club in about a week when my car comes out of the workshop, so just keen to hear of other peoples experiences.

Cheers. Ben

im thinking most people are going to be on the "why would you do that when u can buy a 32r for less than the cost to convert it?" boat.

[play r 32]

i realise this, but when gtrs became cheap i had already spent the money on mine painting it and doing bodykit to make it look the way i want, now it just needs to go fast.. Also while its not the cheapest option building a fast car instead of buying one, it is bloody good fun.

[Boostzor]

Well thats true, as long as you have something to drive for teh few month sits going to be in the shop.

I couldnt see it costing less than 6k and thats if you have pretty good relationship witht he guy doing the work if not its going to be higher. Thing is you tend to think "may as well while im at it" very often which throws costs right up cause nobody wants to do it basic.

Honestly you are better off working on the engine thats in there. The rb25 is not that far off the 26 really and you can get a bunch of power out of it and still have good response if you do it right.

its an r32, probably only has a rb20 in it..

as for the conversion, its not overly complicated, keep the engine mounts, and mounting plates from the 20, and bolt them to the 26, ecu should not be a massive hassle to wire in the stock unit, at a guess, it'll plug into the factory loom without any mods, tho don't quote me on it, but given its a 32, you'll find rhge primary looms are pretty identical throughout the series, and swapping motors is just a matter of pluuging the 26 ecu/engine loom into the factory loom as is..

things you will run into hassle with..

gearbox, forget using the 20 box, you'll kill it in a flash, you'll need an rb25 box, they're about $1500 atm, to get it mounted without butchering a factory gearbox cross member, chance are, an auto silvia cross member will fit up without having to re-drill or weld tabs on as is normally done, you'll also need to sort out the speedo drive, but a navara speedo drive goes straight in and fixes the issue..

the other big issue is the sump, the standard GT-R sump will not fit, you will need to chop the diff off, smooth it down and weld up the old holes that the front diff shaft leaves when its removed, not an overly complicated task, but it takes a fair while of band sawing and sanding it down..

rought cost estimations..

complete cut about 6k

25 box 1.5k

labour?

if you get a complete cut that has the factory cooler, pipe work etc, it should realistically take a good workshop a few days to remove the 20, remove the 26 from the cut, mod the sump, swap over the required parts and drop it back in...

its a pretty straight forward swap..

add to it an exhaust, a new clutch while its all out, and your on the way..

what you can do to make some money back, is sell off the gt-r box, usually they go for about 1k to 1300 bux depending on condition..

trick to it all is finding a good condition cut, and having it come with all the parts needed, but id say, you'll be up for about 10k all up to pull it off..

hey denver thanks for all the info mate. Sounds like your pretty clued up on the hole thing. Mine is actually nearly finished, should pick it up next weekend!

I know what your saying boostzor, with the "while im at it" the only extra i got suckered into was a programmable ecu. my cost for the finished project are

complete engine: $5000

labour, including removing rb20 and painting covers candy gold: $2000

A/M ecu $1200

FMIC $200

so im driving out for $8400

I am using redline oil in the RB20 gearbox for now, my mechanic did this with his own 26 powered gts and its been over a year now and still going strong.

[Denver]

i wouldn't use redline to start a fire..

don't bother bandaiding the gearbox, get a 25 box in it, use real oil, not processed smurf turf, and you'll be happy as larry..

[IMACUL8]

Dont worry about Denver - he's a redline hater.

Redline is great box oil - just like all box oil - change it at regular intervals depending on the harshness of your driving and it's all sweet.

[play r 32]

haha didnt mean to start an oil brand loyalty war! i didnt realise there was that much difference. Il put the rb20 box to test anway lads and let you know how long it lasts. I could go straight for the bigger box but this is good for experimental purposes

[Gav]

There's also a fair chunk of weight saving in the GTS-T without the front diff, drive shafts etc compared to the R.

Keep the modifications focused on good low down torque, set the suspension up for traction (plenty of squat) and don't compromise of tyre quality and you'll have a very quick and balanced car.

[play r 32]

Yeah thats right gav. Ive seen some 26 powered RWDs run some really quick times without huge mods. they sometimes make up for the loss in traction with the weight advantage.

[play r 32]

I havent actually heard form anyone who has already done the conversion. Does this mean there isnt many out there or are you all just keeping quiet so you can sneak around looking like normal gtst's.

I've done it into an R32 GTS4 if that helps any?

Swapped the motor and gearboxes over and left the GTS4 diffs in place ... has 408rwhp atm and in RWD mode is a bit of a handful I think in the end it cost me around the 15k mark but I did a few things like single turbo conversion and PowerFC etc. Good luck with it though - its a shit load of fun as you'll find out

[RRob]

Injector resistor pack will need wired in..

mine wont quite be that powerful but thats what i was mainly wondering, how much of a handful is it going to be in RWD? Its only a light car. But im sure it will be fun as long as i keep it in one peice haha

[AlphA]

Awesome project, will keep my eye on this one!

[GOT BOOST]

been there done that. you'll be in for some fun times for sure.

its been awhile now but i think my std 26 made around 350

with aftermarket management.

and then up to 470 with big single turbo and cams. it was the fastest rwd skyline

in perth running a 11.1 1/4 mile. that may of been beatin not sure.

the conversion is quite straight forward i did mine at home myself.

hey gotboost. yeah i know your car i have seen it around before. It was one of the cars that inspired me to go for the conversion. So far its going really well. I pick up the microtech ECU tomorow and most of the fiddly things are done like making the oil sump. I am replacing the big end bearings in the motor to be on the safe side. Im hoping to be driving it next weekend at this stage, but these things ALWAYS take longer than expected. Spewing its not done for the cruise!

[dr00]

with regard to the gbox, a friend has a 26 in an r32 gtst with 507rwhp and ran an rb20 box for quite a while. it was daily driven, he did a few track days and took it to the drags once or twice. was only starting to get a bit notchy and noisy after well over a year.

[RedLine07]

Ben you know my car, though its a gts4 most of the process was the same. Good fun in rwd, but the heavier weight is noticable. Makes 310rwhp with pfc.

Total cost for mine

gtr half cut (brakes, box etc) $4000

labour $500

fuel pump $200

cooler $200

so all up about $5000, then power fc, injectors, Z32 afms and tune, so with that about 6k.
