Do someone of you guys have a GT35R with 0.63 housing and can tell when the full boost will be available on an RB25? As i read out the 0.82 housing have full bost at 4500rpm with some poncams on an RB25. Thanks in advance.

Hello mate, the engine cam off a 1995 Syline GTS-t Series I, i do not have a VIN because the engine is in my S13 now. I would be very thankful if you could supply me with an engine gasket kit number for a 1995 Rb25DET Skyline. I do also need the part number of the complete clutch master cylinder of the R33 Skyline GTS-t Rb25DET. Thanks in advance. Greets, Artur.

Hello guys, im actually searching for a R33 GTS-t RB25DET complete engine gasket set-number, i would be very thankful if you could supply me with one. Greets, Artur.

Hello guys, i'm actually looking for a complete RB26DETT Manifold bracket in full functional and good condition which should include the manifold itself, the throttle bodies+bridge, the water/injector bridge and the fuel line. I do need the whole bracket, just as on the images shown below, except the injectors and the aac-valve. I appreciate offers by a private message . Greets, Artur.

Hello Guys, i'm actually looking for the rear R33 GT-R calipers, i just do need the calipers with or without brake pads. Also im looking for a R33 GT-R brake master cylinder and a brake booster. I do not need any R32/R34 or R33 GTS-t parts. The parts should be in a full working condition and in a good shape. I'm looking forward to receive offers, if possible with pictures by a private message. Greets, Artur.

Hello guys, i do need a RB25DET oil sump in a good condition, it can have some little scratches/rust on it but shouldn't leak and should be in a good overall condition. I'm looking forward to receive offers by a private message. Greets, Artur.

Hello guys, i'm actually looking for the whole and complete Blitz kit which allows me to mount RB26DETT throttle bodies and plenum on my RB25DET head. I would be thankful if someone could supply me with the information where i can buy this kit or maybe someone here want to sell his kit. I'm looking forward for offers by a private message. http://www.rb30.com/rb25-6.htm Greets, Artur.

Hello guys, i think it was already mentioned but do you have any sources for the block off and 1.0mm oil restrictor for my RB25DET ? Where can i buy them ? Tomei is only selling the 1.5mm oil restriktor and no block off plug. Thanks in advance.

The thing is that i'll need solid lifters, other springs and all of that for more aggresive cams, i wouldn't hesitate buying these parts but i think solid lifter are not necessary as i dont want to rev over ~ 8200 (redline) as i think the GT35R with A/R 0.86 will start loosing power beyond 8000 rpm.

Thanks for the information, are there any other places where i can get those if tokage cant supply me with this conversion kit ?

Thanks for the information so far guys. However are there some 260° Type B Poncams out for the RB25DET S1 ? Highoctaneracing is offering these but on tomei's official site 260° are only listed for the NEO RB25DET out of the R34 ?! So are there 260° Poncams available or not for the Series 1 Rb25DET i have ?

Thanks for the reply so far Guilt-Toy and Adriano , are there any other opinions ? I think the turbo choice will be the key for choosing other components, however i'm favouring the Garrett GT3582R .82 A/R by myself for a long time now.

Hello guys, as Gary is on holidays for 5 weeks i do not have somebody other to ask then you. So i would appreciate it if only really qualified members would answer my questions. Alright, lets come to the matter im currently building my RB25DET up for drifting (70%) and circuit racing (30%). I do want to run this engine with 100 octan fuel all the time, also the engine won't see street action, this engine is for circuit use only. Thats why i dont care how hard the turbo is coming, it just need to match its purpose, drifting + circuit racing. My questions: 1. Ok, one big question for me is if i should go for a Garrett GT3076R or Gt3540R, which one would you recommend for the stated above power figure and which Ex A/R should i choose ? I think these are some interesting turbochargers for my needs: Garrett GT3076R .82 A/R Garrett GT3076R 1.06 A/R Garrett GT3582R .63 A/R Garrett GT3582R .82 A/R 2. The next thing would be which kind of metal head gasket should i use, i have 86.5 wiseco pistons and i think a 1.2mm Greddy one would be enough as i dont want to run more then 1.4 bar of boost. What thickness would you recommend for my power goal / boost pressure ? 3. What kind of cams would you suggest me, i do already have the Tomei Poncams 256 in/ex and would swap them for 260 Poncams if they would match the new turbo better. 4. What kind of oil pump would you recommend me ? The engine will have a hard abuse all the time. Nissan OEM ? N1 ? Jun ? 5. What do you think of an High Energy PRO CIRCUIT LARGER CAPACITY SUMP as i will drive with semis on the circuit ? Would you suggest this oil pan or would be the standart one good enough ? 6. What kind of intercooler piping would you suggest me ? Complete 3" or 2.5" or 2.5" on the hot side and 3" on the cold side ? 7. How long would the transmission last with the stated above power figures and hard abuse ? Would you recommend me to completly overhaul the transmission and put the complete OS Giken 5 Speed set + input shaft in it ? 8. Which head studs are good enough for the power i am aiming for, standart ones or do i need ARP studs ? 9. Are the Nismo 555cc injectors big enough for my power goal or are do i need bigger ones ? 10. What size of wastegate would you choose ? 48mm or 52mm ? 11. Would you port your head ? Is it really worth the money for the ~ 0.2 bar overall less boost i need for the same amount of power ? 12. Will the Z32 AFM hold up to his job, how much hp will it support ? Alright i think that are all of my questions, please do not forget that this engine is for a race car not a daily or weekend driver. Do not worry about suspension and brakes everything is upgraded to hold this amount of power and a lot of more. I would be very thankful if you guys could help me.

Hello guys, i do want to install the RB26DETT throttle bodies + plenum on my RB25DET i do know that BLITZ is making adaptors for this conversion and yes i know that they are expensive. However do somebody of you know a shop where i can get this adaptor as i cound't source one expect ricohracing which aren't replying to my emails. I would be very thankful if someone of you guys could help me. Greets, Artur.

Do you or somebody else do know where i can get this Blitz adapter kit ? I would be very thankful if somebody could help me.

Come on guys, somebody should know it, it's important.

Do anybody know if the A31 cefiro and the S13 subframes are the same ?

Hello guys, i'm asking myself if the R33 GTS-t calipers are made out of alu or steel, or are there two versions out ? I'm looking forward for a reply. Greets Artur

I tried to install such a 76mm tubing on my S13 also and i had no chance of fitting it because my front rims/tires (17x9" +15 with 235/40) are too wide and do not give me enough place to put a tube between the body and the tire when i had full steering angle.

Thanks for the reply. I have one other question, are the front lower arms of the cefiro the same as the S13 ones ? Im asking because there is an option to use S14 5-Stud knuckles in front and i do know that s14 knuckles can be used on a s13 with a custom made ball joint which will get pressed in the S13 OEM lower arms. Ball Joint:

Hello guys, i'm not that into the ceffys as i'm a S13 guy, so here are some questions from me. I think the brake lines from the S13 and A31 are 100 % identical (Fitting on the caliper side and the fitting to the body side of the car), right ? Do i need custom made steel braided brake lines to install R33 GTS-t calipers all round on the ceffy ? I would be very thankful if you could help me regarding this case. Greets Artur

Still searching...

Hi guys, im after a R33 GT-R brake booster with the brake master cylinder (the one with ABS), i would prefer both as a bundle but i appreciate offers by a PM for one of these items also. I do not need the GTS-t or R32/R34 stuff, thanks. Greets BH

Hi guys, are there any differences between the R33 GT-R and R34 GT-R V-Spec, V-Spec II, N1 brake booster + brake master cylinder ? I'm asking because the R34 GT-R have slightly bigger brakes in the rear on the V-Spec, V-Spec II and N1 models. The normal version of the R34 GT-R (none V-Spec, V-Spec II, N1) have exactly the same brakes as the R33 GT-R, so the brake booster + bmc should be the same. Maybe someone of you could help me regarding this case. I'm looking forward for replys. Greets BH

Hello Guys, i do need pictures of an 180SX (RPS13) with an A31 Cefiro crossmember and installed RB25DET. I do need these pictures to compare the engine position with an installed R33 GtS-t crossmember. There are a lot of pics with r33 crossmember arround but only a few with the cefiros crossmember. Also i heard that you can use A31 Cefiro front driveshaft and S13 rear driveshaft to make a perfect fitting driveshaft with the A31 crossmember, is this information right ? I'm looking forward for an reply. Greets BH
