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 have 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 just 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

      HR34 GT speedo issue

      By isf · Posted

      The odometer does go up when driving.  Does this tell it is an issue with the speedometer itself?    Where can I look for replacement cluster? Or speedo? I can likely do the repair.. Will ER34 cluster work on HR34? Or do I need a HR34 20GT S2 specifically lol

      Steps to DIY sanding car back ready for respray....

      By silviaz · Posted

      Mine's a bit bigger at 70x150mm roughly. The spots are flat, just can feel the edges if I dig my nail into it. I did fix some other other ones by both using my finger to sand that small spot (I'm a bit wary of doing this and creating hot spots and a bigger mess) and I also did sand over it flat and others, but this also worried me a bit because if I create an overall low spot on the panel on paint that is good.  Correct me if I'm wrong but as long as it's flat even if I can feel the edges, I can put filler because it will all be level once I sand it? I can see myself going in a circle after sanding guidecoat with 320 grit if for example the panel is flat with my hand but because I sanded the guidecoat I could have created a low spot again somewhere. Unless where I'm going wrong is what I mentioned previously where I didn't go low enough on the grits. It's 1 step forward and 2 step backwards here haha. I'll probably need to experiment with it more. Last time I go back to bare metal lol.

      Who has a Infiniti Q60, Q50 (V37)?

      Thanks for the details mate , for me I think being a daily driven and happy with a basic tune (630Nm and 310kw) . Seems to be working well I just put on a set of Michelin Pilot Sport 4 should help put the power down. I'm going to start looking a brakes and LSD in the future so I might reach out to you on options to upgrade the brakes. Cheers - Dee

      HR34 GT speedo issue

      By isf · Posted

      I have a HR34 GT... RB20DE My speedo doesn't work! The rest of the gauges seem to work, fuel and RPM. I did not notice if my odometer was going up when driving last.  Any ideas? Speed sensor? Hopefully atleast... Gauge cluster perhaps? Or is that unlikely because the other gauges are working?   Any insight is appreciated. This is a rather new to me car. Lol
