Hey guys,

I went into the RTA today and asked about engine conversions, and what’s required etc.

Basically I wanted to upgrade to a turbo-charged engine, However that would require too much effort. So I asked about the Rb25de upgrade, and the fellow said that it was fine as long as the car came out with the same suspension, and brake setup. He told me that I had to get real documents from the Nissan dealer, but being an import I wasn't sure if they would have them.

So basically what i'm after is the stock non turbo 1995 R33 GTS25 specifications. I have a non turbo 1995 R33 GTS which is a 2.0L but I wouldn't think the brakes would differ from model to model.

So if anyone has these details (yes I’ve searched) it would be helpful if I could get them. Also I was thinking about going to the Nissan dealership tomorrow, but does anyone have any idea if they carry this information on their computers?

All I require is the dimensions of the brakes, and basically suspension setup, years released, type of engine etc.

Thanks in advanced.

Dayne :lol:

the simplest way to do it it to swap the brakes from the rb25de donor car. or go to a wrecker and measure the diameter.

you can go the turbo route many have done it my self included (on an r32) swap engine brakes and rear diff and you have have an r33 turbo spec. car ore pricey though.the performance difference from the rb 20 e to the rb25 de is pretty good. my cefiro with an rb25de made 105 rwkw the rb20e would have been lucky to make 70 rwkw.

good luck

btw there is some infomation on these pages on my site

as far as i know the brakes onm the turbo are 5 pot with the brake pads being the same aswell as the rotors being slightly larger. As for the suspension it should be the same, but i think maybe go to one of skylinekids group buys is the way to go, i also think you hay have to change gear box and clutch...

my pod filter adapter was the same as an r33 gts25t

the r33gts25 have:

twin piston sliding calipers for the fronts

single piston sliding calipers for the rears

the r33 gts25t have:

four pot sumitomo calipers for the fronts

twin pot sumitomo calipers for the rear

the turbo calipers are bigger and chunkier (from 6 pots total na, to 12 pots total turbo) rotors are bigger and chunkier.

i wasnt asking about turbo, i was asking simply the specifications in (mm's) of the size of the rotars on the Na.

The pod filters dont fit? wtf thats odd.. mine was off a r33 gts25t and it fit straight up. Brake pads..? the brake padds are only listed for rb25de, rb25det and rb26dett in the 1995 skyline range, so i dont see how you could of got gts padds.. maybe the guy just had no idea?

Thanks for all the info though everyone, specially Eug. That was heaps helpful. Just one question though how can i tel the sliding calipers and how many pot they are?

Cheers

give me a minute mate and i'll take a photo of my old calipers

These are R33 GTS25 calipers, they came off my 1994 GTS.

and these are 4 pot sumitomo calipers - these are R32 GTSt , but the R33 GTSt ones look very very similar (minus the ribbed bits on the top)

DSC00659.JPG

very noticeable difference between the two types. (i know you didnt want turbo specs - but just to compare and show the difference)

anyway the R33 gts25 rotor specs for the according to dba are as follows:

FRONTS:

Vented, 280mm diameter, thickness including hat = 49mm, thickness of the rotor disc = 26mm,

I cannot find any specs on the rears, and i dont have my rear rotors and calipers anymore because NA_R33 (John) has them now.

      I appreciate the detailed explanation, think I understand now. I spent the better part of last night reading what I could about shuffle and potential solutions. I had replaced the OEM twin turbo pipe with an alternate Y pipe that is separated further away from the turbo. The current one is from HKS and I had a previous pipe that was separated even further away, both have shuffle. I had heard that a divider can be welded in to the OEM pipe to remove turbulence, and figure that aftermarket pipes that are more separated would achieve the same thing. From what I read, most people with -10 turbos get shuffle due to their size, though it's a bit less common with -5s on a standard RB26. I think Nismoid mentioned somewhere it's because OEM recirculation piping is common in Australia with -5 cars. It seems that the recommendation tends to vary between a few options, which I've ordered in what I think is most feasible for me:  1. Retune the MAP or boost controller to try to eliminate shuffle 2. Install OEM recirculation piping 3. Something called a 'balance pipe' welded onto the exhaust manifolds. I don't know if kits for this are available, seems like pure fabrication work 4. simply go single turbo My current layout is as follows: Garrett 2860 -5s HKS Racing Suction intake MAF delete pipes HKS racing chamber intake piping hard intercooler piping,  ARC intercooler HKS SSQV BOV and pipe Haltech 2500 elite ECU and boost solenoid/controller HPI dump pipes OEM exhaust manifolds HKS VCAM step 1 and supporting head modifications Built 2.6 bottom end All OEM recirculation piping was removed, relevant areas sealed off I'll keep an eye out for any alternative solutions but can get started with this.  Only other question is, does shuffle harm the turbo (or anything else)? It seems like some people say your turbo shafts will explode because of the opposing forces after a while and others say they just live with it and adjust their pedal foot accordingly.

      Can you mount the ATTESA pump in other locations?

      That worked out PERFECTLY! Thank you big time to JJ. He was able to swap me his stock diff. He drove all the way to me as well. Killer! Removal & install was pretty straightforward. The diff itself is HEAVY. So that’s a 2 man job.  Man does the car drive nice now! Couldn’t have worked out any better 👌
