Hello

I am looking for 250rwkw from my RB20. Currently I have a RB25 turbo on it and I am wanting to upgrade to a bigger turbo.

What cams would be good for this engine? I have a set of HKS 272 9.5lift RB cams sitting around. Would these be good or should I go with the Tomei Poncams? If Tomei which size would be good for my engine?

Help please

I don't think HK$ sells the 272's anymore, at least when I was looking for cams I couldn't find any. I got the Tomei 270's.

Way too big.. Response, spool and no doubt peak power will suffer with such big cams when aiming for 250rwkw.

I would consider a set of 256mm cams.

IMO if your going to go to the effort of fitting cams i would look at 264's rather than 256's but you would see better gains with a different turbo.

A friend gave me the cams. They are RB cams. So with the duration being 272 that is too much and it will make me lose power and give me too much lag?

What turbo would be a good match with 264 or 256 cams? Which Tomei cams, Pon or Pro cams?

      Leak from Tokico BM50 Brake Master Cylinder

      By brillo · Posted

      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.

      Starter motor replacment teeth count.

      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 All below part numbers have been superseded to 11 teeth.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

      J50 clock date suddenly reset to January 1

      Low battery? Maybe check capacity? I know first-hand, on BMWs if your battery drops below 80% capacity, it starts causing strange issues.

      8.5 +37 = should fit rear, but I think it'll hit on front. What you want is low 30s/high 20's front, mid 30's rear. That 17" screenshot you posted looks good, I'd run it on my R32 (but that's long dead now). For tyre sizes, my rule of thumb is: 8': 235, 9": 255. But that's just my opinion. Nismo sizes: 18x8.5+35/18x9.5+38 is a good starting point.
