Is it possible? I am about to pick up a bottom end for crazy cheap (built) and i was curious if this is possible at all. I've searched all over the web (skylines AUS, and etc) and came up with nothing.

Here are the specs on the block.....


R34 RB25DET Block
.40 Over Bore, Line Honed, Deck Re-surfaced & Micropolished
R33 RB26DETT Crank, longer Crank Collar
R33 RB26DETT Rods, Micro-polished
CP 87mm RB26DETT Pistons, 8.5:1 Compression, CP Piston Rings
ARP Rod, Main bolts
ACL Race Rod & Main Bearings
Tomei Oil Restrictors

here are the specs for the bottom end:
Cylinder Bore Size 87
Piston Stroke Length 73.7
Head Gasket Bore Diameter 88
Piston Deck Clearance Negative If ABOVE Deck (Use '-') : -0.5715

why would you not want the NEO head? Its better, Soild lifters more agressive cams and I believe the head flows better

Due to my car being set up for the S1 that is already in the car. I'd have to get a completely new wiring harness and etc. I just desire a built bottom end. And plus there is a plethora of parts for the S1 and S2. Not so much for the neo.
