Z20leh issues

[nova_sr_boi1991]

Just bought an Sri Astra turbo running near 300bhp has loads of regal receipts and Courtney receipts but suffers from a running issue it has new airflow metre but still farts and bangs? Any ideas and also the ring gear has come off the starter so what flywheel can I swap it for? 20xe?
Cheers

I'd replace it with another LEH flywheel.

Running wise, i'd be looking at fuelling. What mods have been done?

Are they hard to get? Would a 20xe fit? It has vxr turbo, injectors, hard pipes, stage 3 map, front mount, vxr airflow and Astra dti air box, bigger downpipe, 3 inch exhaust etc

No clue and no clue. Maybe get the map checked.

re the receipts... what exactly are they for?? parts or work???

[Jon_nova1]

is this by any chance a blue one? my mate had one a couple of years ago tuned by regal, could ask him about it if it is

[nova_sr_boi1991]

It's black mate and receipts are for parts and fitment

Who did the remap?

My Zlet did similar stuff when the boost solinoids fcuked, could be that

This the one with the 888 built LEH engine?

Lex engines pop and bang anyway.... My Vxr does.
