Hi all,

I am about to start a rb20det stroker project and i just cant seem to find what im looking for.

Heres a quick run down of what i have.

RB20det- full engine just very worn out and smokie( but sorta still runs)

RB25det- crank, rods and pistons (A1 condition)

Rb25 head (complete) A1 condition..

i've read a lot of posts about people using RB25 Crank, rods and I think 4agze pistons to make an RB21 or RB23 im guessing, i cant exactly remember what combination that makes.

My questions are has anyone ever gone all out using The full bottom end from an Rb25? and does that even work or be compatible? an other idea i had was using the rb25 crank rods and Standard RB20 pistion.

second question. i was also thinking of using the rb 25 head mainly because of the variable cam timing. is it easy to adapt? apart from what i can see an extra oil port near the front of the head.

i was just thinking of doing an rb25 conversion to my R32 but i cant let all these parts go to wast lol and i love engine project.

Third and final question.would anyone have a copy of a map i could use for this engine so once i do get it all complete, she wont run lean and melt.

Cheers

      Physically, you'd expect it to turn the motor 11/8ths faster than a standard one, but I'm not sure of specifics

      Ironically the GTT was quite reliable in the 7 years of ownership. From memory I've only had to replace a radiator and coilpacks out of inconvenience

      Leak from Tokico BM50 Brake Master Cylinder

      Yes I can see how that would put you off HFM, especially with the price of good quality brake fluid. From what I understand it as you say the BM50 is the standard BMC for a R32 GTR, I must admit I would like to go far a Genuine Nissan BM57, but lack of cash prevents that at present. With the price being so close between the genuine BM50 and BM57 a BM57 New it seems a better choice as you gain that 1/16 bore size with the BM57, I would be interested in how much difference you feel with the BM57 fitted. I am going to take SteveL's advice in the short term and see how much actually comes out of that proportioning valve vent and save up for the Genuine Nissan part. Thanks for clarifying the HFM failure

      Thanks mate. I just got the post inspection 1/2 done from state roads when the starter motor packed up, either that or the car alarm system is having trouble.  OEM part number 23300-AA112.

      Hi, I though I was coming to an end in finding a replacement starter motor for a rb25de neo. I came across a starter motor from Taarks and a message below stating: Direct fit. 11 Tooth count. All below part numbers have been superseded to 11 teeth. Can some body shed some light on going from 8 teeth to 11 teeth apart from 36-month / 25,000 km warranty for passenger vehicles to 12 Month Warranty. Compatible with the following Nissan part numbers: 23300-20P00 23300-20P01 23300-20P05 23300-20P10 23300-20P11 23300-AA111 23300-AA112 23300-AA300 23300-08U10 23300-08U11 23300-08U15
