Brief background: Car is a 2g GSX that currently has an old "Stage 4" 6-bolt SBR 2.3L in it. It spun a bearing last summer due to an oil-cooler failure. I split my time between Australia and the US (where the car is), and will be state-side at the end of July for a couple weeks. I want to fix the car then, so I'm looking for a ready-to-go shortblock that I can swap in while I'm home (don't have the time to have the current shortblock - which is still in the car - rebuilt). I'm currently torn between these two options, both about the same price:
Option A:
2.4L G4CS
Weisco HD 8.5:1 Pistons, Ceramic Coated
Eagle Rods
Clevite 77 Bearings
Standard Main Studs
No Oil Pump (provide my own)
Option B:
2.3L 6-bolt
Ross 9.0:1 Pistons
Eagle Rods
ACL Main/Connecting Rod Bearing
ARP Main Studs
OEM Oil Pump w/ Straight Cut Gears
Car is being build for HPDE/Time-Attack work. I have 93 Octane available, and will be pairing this with a billet bastard 20G built by JuaMX141, which he said should be good for airflow in the the 47-48 lb/min range.
Which would you go with if you were me?
