So Ive got a S2 R33 standard engine. Normal entry level mods. Ie. vg30 turbo, elec boost controller, Alexi power fc, fuel pressure reg and a front mount.
My poor skyline has been sitting in the back yard for a few years while life got in the way and me finishing of a new engine for her. I’ve been starting her every few months just to keep oil moving. Anyway I have now registered her and started driving her while I rebuilt a engine for my hilux. When I first started her she ran fine took her down the servo put some fresh fuel I. Her and thought all was well. After a few days she started miss firing while coming on to boost. Now she is hard to start. Won’t rev past 3000rpm ( roughly ) when boost comes in.
I assumed stale fuel had blocked up the fuel filter. So I changed that and put some new plugs in her. No change.
Has anyone got any ideas?
