hey all just got a couple of quick questions as i'm slapping together a rb2630 out of parts i have laying around... 

the plan is to slap one of my 26 heads i have laying around onto a good condition standard rb30e bottomend i have aquired.. i have everything laying around for this except for the timing belt kit and my head bolt/stud issue.. 

my main question is about the head bolts/studs considering the 26 runs a larger size... 

Will there be any problems with me just using arp rb25 head studs? with out getting anything else even tho sleeves to sit in the 26 headbolt holes to comensate for the narrower head stud would be ideall... but this is a very very budget slap together out of parts i have laying around unless there is somewhere i can buy those sleeves providing they arent to costly... 

OR would i be better to take the complete short block into the machine shop and see if they'll drill and tap it with out pulling it apart (i dont think they'll like that idea :) )

Thanks in advance

You can use rb25 studs as some guys here have, no modifications to the rb30 holes

Sure you dont want to freshen up the bottom end b4 u slap it together?

nah.. no need to freshen it up.. this is just a slap together out of boredem, motor was in good working order with good compression before it was pulled out... only reason it came out was for a 2530det to go in

spoke to the machine shop today and they've said just use 25 studs aswell as the head is doweled so there shouldnt be any problems with slop in the head

Just do what I did and order a set of Durapro Bolts. Cost me $50. Nissan quoted $180 for a set of standards..

The Durapro and Nissan bolts are the exact same torque settings. The engine builder said they may even be the same bolts.

use new studs, i can tell you now reused ones fail. We tuned a 250000km $150 wrecker NA rb30e (still single cam) @ 22psi (300rwkw) and the brand new gasket failed due to poor clamp pressure (pushed into coolant channel) fitted new studs and it has run like a charm.

      Update: tested my spark plugs that are supposed to be 5ohms with a 10% deviation and one gave me a 0 ohms reading and the rest were 3.9ohm<, so one bad and the others on their way out.

      9" wheels are a little too wide for a RWD 32. They can fit. People have put R33 GTR wheels on 32s for years and years. But they are a very tight squeeze. This has been known for about 30 years. As I said - there is no difference between a 17 and an 18 in terms of what will fit. The rolling diameter needs to stay about the same as stock - not very much larger. If you increase that, you will start to have problems. If you increae rolling diamater at the same time as yo increase width, you will have problems earlier. as 9" wheels are pushing the boundaries already, you would need to be careful with tyre choice. I would put 8.5s on the front of mine, but would expect problems with 9s.

      Diagnostic flow for a code 21 says check signal at the ECU pins, on a voltmeter of some kind it should read 0.1V at idle, 0.12V cranking, 0.15-0.25V at 2000 rpm. Check each coil such that +1, -3 is infinite or very high resistance, -3, +2 should do the same. (-1, +3), (+3, -2), (+1, -2), and (-1, +2) should all be somewhere between 0 ohms and high resistance. If you trace the path from the coil pin all the way back to the ECU in the diagram the resistance you measure at the coil vs connected to the harness should be pretty much the same.

      I have an elite 2500 running an adapter harness on an rb25de neo r34. I took the butterfly out and removed all that junk. But I also went Plus+t at the same time. The butterfly thing works in reverse to the boost solenoid on the Gtt if that makes sense
