Administrators gav240z Posted March 17, 2014 Administrators Posted March 17, 2014 Hi Guys, As you may have seen in my Safari Gold project thread, I've discovered my E31 has the small L24 size valves and my F54 block has a set of dished pistons which I believe would give me a CR of ~8:1. So I'm looking at some options and thought I'd post and see if anyone has a P90 they might be willing to part with? You can get them rebuilt in the US pretty cheap, but I suspect shipping will be the killer given their heavy weight. http://www.ebay.com/itm/Datsun-Z-240Z-260Z-280Z-ZX-Rebuilt-P90-TURBO-Cylinder-Engine-Motor-Head-/151234217839 Feel free to PM me what you want for 1 if you have 1? Will consider any condition - would prefer something that hasn't been messed with too much if possible but all options considered pending price etc..No rush on this end, going to be tearing into the block first but figure I'd put this up as a starting point etc.. Cheers, Gavin Quote
Moderators Zedman240® Posted March 17, 2014 Moderators Posted March 17, 2014 Gav, I think a P90 will lower your ratio even further. You'll need a N42 to get the CR higher. Quote
Riceburner Posted March 17, 2014 Posted March 17, 2014 My old L28 was a P90/F54 comp ratio was 8.3:1. Still went ok Quote
Administrators gav240z Posted March 17, 2014 Author Administrators Posted March 17, 2014 I plan to change pistons and I'm looking to use the LD28 crank and L14 rods I have also. Just seeing if anyone has 1 and at what price. Fall back option is N42 but I haven't ruled out the E31 yet. Quote
