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.

      The fancy pants red shock tower brace is finally incoming from MX5 Mania, getting it shipped from 'Merica has been a long and problematic process, and GWR, the 'Merican supplier will not ship directly to consumers outside of the US, Mania basically had to order a heap of them, the colour choice was silver, or red, and we all know anything red adds 5 killerwasps of dynotorques..... Whilst it does fit over a 2.5, and I've seen a few photos and videos of it being installed and fitting, google also says it might get real close to the FAB9 intake front runner, people in the US says it does fit with the FAB9 intake, except for one person who said it slightly touched.......so there is that.....LOL..... As it seems that I am the first in AU to have this combination of parts there's no local knowledge about fitment, so I'm just a willing guinea pig in this endeavour, I'll cross my fingers and toes and hope for the best In other news, I ordered stuff from China  on the same day I ordered the 23° silicone bend from Victoria, the stuff from China arrived a day ago, the 23° silicone bend is still travelling around Australia thanks to Australia Post, and "may" be here next week

      Very good news...I contacted Racebox about it last night. My car is a 2016 so remains to be seen if it is compatible, requires a TCU swap, or is impossible.

      What ECU are you running? This is probably the biggest question. If it's a PowerFC, I'd probably change the ECU and get something newer that will handle the injectors in a nicer way.
