Keep up the great discussion guys

Some interesting alternatives from the professionals. As many know I did an RB30 into an R32 GTR about 5 years ago using a 4wd adaptor plate made by our race car fabricator. I used an RB25DE (R32 style) cylinder head. It was a cheap way to get an engine into a GTR at the time (cost less than $2K all up). It is still running fine too making it's usual 300 rwkw.

Next time I do a 3.1 litre GTR this is what I intend to do;

* RB26 block (I have a suitable one) with an O 'ring receiver

* 98 mm OD 86mm ID liners, with a machined step down to 90 mm to fit the block

* RB30 crank (linished, screwed and balanced) standard 85 mm stroke (I have several to choose from)

* Argo RB30 rods (I Beam with 22 mm gudgeons)

* JE VG30 87.5 mm pistons (they have 22 mm gudgeons) that will give me 3,068 cc's

* Total Seal gapless rings (I have had good success using the gaples 2nd ring)

* Billet alloy 30 mm block spacer (so I can use the RB30 conrod length and retain the 1.79 rod stroke ratio) O'ringed top and bottom. I used an RB26 head gasket as a template.

* 2 double annealed copper head gaskets (one between the block and the spacer and one between the spacer and the head)

* ARP 1/2" head studs (they are going to be long, and need to seal 2 head gaskets, so I want a good clamp)

* ARP main bearing studs (as usual)

* RB30 ACL Race Series bearings

For way less than 1/2 of an OS Giken 3 litre it should be interesting
