I need some help, i blew the head gasket on my engine (rb 20e) when i pulled off the head the water ports were all eaten away. I purchased a 2nd hand one which was in good condition. every thing is bolted up, now i need some help with setting the timing.

1. how to position the cam and crank, what markings to look for

2. how to position the distributor.

any help would be good, i know i should have just put in a 25 and done the talk, but my funds would not allow that, so for now i just need to get her back on the road.

thanks

quick question, when the new head is being bolted on should the pistons be at tdc?

the reason i am asking is that i bolted on the head and lined up the cam with the required markings, however, the crank only turns 180 degrees and then locks up. as if it was bouncing on a valve. i did not put the pistions at tdc before bolting on the head. could this be the reason?

any help would be good thanks

    • 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 All below part numbers have been superseded to 11 teeth.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  
    • 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.
