R33 Gts4 Or Gts Engine Conversion To Rb25det

[shorty_01]

Hey all,

I currently drive a R33 NA 96 Gts4 skyline n looking do rb25det engine swap...WITHOUT turbo charging my current motor i.e the rb25de

Ive read the forums n check out how ppl turbo charged there na skyline. all is well however,

What i wanna know is.. is there any out there has done an engine conversion for a GTS4 or GTS using an GTST Rb25det engine??

I am aware that if placing a Rb25det motor in a GTS4 i will need to modify the sump due to the Attessa 4wd, get a: turbo back exhuast,fuel pump, intercooler n up graded breaks.

If any has done this conversion whether on a GTS4 or GTS, can u tell me the problems you experienced down the track eg gear box slipping etc. any other suggestions!

This be greatly appreciated!

Regards

Shorty

You wanna do what?

if you already have R33 GTS4 then you should have RB25DE.

ok I got that part.

but you want to do RB25DET conversion but DO NOT want to TURBO charge it?!?!? WTF? and why not?

ok I think you are confused about all the lettering in SKYULINES.

GTS4 = GTS Skylines with 4WD ATTESSA system Non-turbo RB25DE or RB20DE

*when some one says I have GTS4, it means he has 4WD ATTESSA system not he/she has 4doors*---LOL - common mistake with noobs

GTS 4 Door = GTS skyklines with 4 Door NO ATTESSA Non-turbo RB25DE or RB20DE

GTS-R = R31 Skylines with RB20DET (2 Door only me think)

GTST = GTS Skylines with RB25DET (series 1 &1.5) 2door and 4door

GTS25T = R33 GTS skylines with RB25DET (Series 2) 2 door and 4door

GTST 4door = 4door skylines with RB25DET.

so if you have 4WD 1996 R33 GTS4 (series 2 I presume), then you dont have to do anymodifying, you need $7000 for RB26DETT engine + labour , new breaks, looms, ECU...etc...etc.

Does this help?

[Pva_Glue]

also if you have 1996 R33 GTS4 then you should have ABS also.

if you want to go turbo you will need a rb25det out of a 4wd stagea. there pretty rare so you would be better off just converting your engine to turbo. if your worryed about compression run a thicker head gasket or get your engine rebuilt with turbo pistons.

then all you need is turbo, turbo manifold, injectors, AFM, turbo ecu(if there is any difference), intercooler and pipes and a few other little things. its been done meny times before and most people dont have any problems running it on stock internals. you just have to rember you cant run alot of boost.

lmao @ PVAGLUE....

i think what he's getting at is that he wants a turbo motor (without turbo charging his current motor i.e the rb25de)

basically you've got 4 options:

- rb25det from a stagea, it will be an auto (like geoff said)

- rb26dett from any gtr

- rb20det from an r32 gts4

- turbo your current motor

go from your budget and application, then work from there.

[shorty_01]

hey,

Thanks for replys all!

I have a series 2 2 door GTS4 ( yes with 4wd attessa) . I have heard if placing an RB25det in to the engine bay all i need to do is adjust the sump?

Stagea engines are hard and too long to source. Botling on a turbo means stock internals no high boost...

So has anyone done this type of turbo engine convserion (gts4 or gts )???? IF so can u PM with info. Cheers

Thanks peoples

i cant belive ur still asking about this ... from memory u asked me ages ago but not to worry

my advice is just wack a turbo on the DE motor then its basically a NEO motor (R34 RB25DET NEO runs higher compresion)

you could give steve from manta racing a ring or shaun from boost worx

Manta Automotive Services Richmond 08 8234 8688

Boost Worx Hi Performance Panorama 08 8299 0621

i cant tell you where mine gone done because i bought the car like it if u really want i think i got the dude who owned the car and i could try ringing him and asking

1 other note is there is a possability that the crown gears may get chewed due to more torque and power

ive had to replace my from crown and it hurt the wallet big time and we never did get to the cause of the problem :S

[shorty_01]

ahh Madaz, u still memeber LOL!

Thanks mate for info. Man Crown Gears.... shits... sounds bad.

Ill give boostworxs a call.

Yeh that would be grealty apprciated if u could get into contact with prevous owner. Just enquring about the SUmp adjusted in the GTS4. Btw my rides an auto -_- lol.

Aint autos transmission meant to have kick ass durability in the skylines?

[shorty_01]

perhaps a Stagea engine with gear box... to prevent my current NA gear box from dying..

[Madaz]

i know the guy that did my front diff says the gear boxs are the same to the turbo 1 my box has been given heaps and its fine but front gears let loose for sum reason

[Madaz]

u might want to catch up and we can chat face to face u can have a look @ the job done on my car and go from there

wot u have to take into consideration is that chaging from R33 engine to stagea u need to change all crown gears cause imo stag run different ratios

[RoD]

So is everyone here saying you can't just remove the RB25DE and drop in an RB25DET from an R33 GTS-t?

u could but u have to remove sump and put the attessa sump on and that has the diff attached to it and the axel running through the midle of it

in my opinion least hassel cheapest option would be bolt on turbo and get ecu and all other bits

sorry shorty cant find the guys number that owned my car i think i threw it away lasat weekend

Hey madaz,

all goods mans,

Spoke to Shuan from boostworx like a month ago n he qouted me 3,500-4000g for total engine transplant with sump adjusted + tuning+ inc labour.

But i have family mechanic who can do it for cheaper rate =P

Yeh i think its a good idea we catch up n i sus ya ride out. Whenever is fine. Perhaps over this long weekend.

[NA_R33]

yeah dude, u need to use the same sump u have now the front diff is part of the sump, from memory im pretty sure u just buy a turbo motor and use your current sump.

[blind_elk]

I did this conversion for my R32 GTS4 - I chose to use the Stagea engine. It is highly doubtful that a RB25DET (RWD) block can have a AWD sump bolted to it.

Ahh... so u put a Rb25det into ur R32 Gts4? How much did your stages set u back & where did u source it from?

Also Madaz said.

"wot u have to take into consideration is that chaging from R33 engine to stagea u need to change all crown gears cause imo stag run different ratios"

Did u do this blind elk?

Thanks

I managed to find one at Central Motor Wreckers in Ballarat - $4G, engine and (auto) gearbox only. All-up cost was around $8G, after converting the engine to accept manual gearbox, and adding Wolf 3D ECU.

The Stagea runs 4.083 diff ratios - it is relatively easy to swap your current diff (crown wheel AND pinion gear) into the Stagea housing. I eventually changed to the Stagea ratios front and rear, because the RB25DET had so much more torque that I didn't need the standard (R32) 4.375 ratios

Hey Blind elk,

" The Stagea runs 4.083 diff ratios - it is relatively easy to swap your current diff (crown wheel AND pinion gear) into the Stagea housing. I eventually changed to the Stagea ratios front and rear, because the RB25DET had so much more torque that I didn't need the standard (R32) 4.375 ratios"

That sounds pricey man.... can u give me an estimate using aftermarket bits please.

Greatly appreciate the feed back people.

I think this topic will be of good use to future ppl who want to do this . And i believe i be the 1st to post info n progress aboutit. So its good for all =)

Keep your ideas n opionions coming !

SHorty =)
