Hey all as you know I blew my lnf up like 4 months ago. So I bought a new ldk from zzp and I'm doing a minor build. So far I have bought Opel injectors and the upgraded fuel lobe cam. I'm currently saving up for the zfr71, south bend stage 4+ clutch, new flywheel, zzp trans mounts. Still have a lot of work ahead of me. I still need to tear apart the old motor to see what went wrong. Once it warms up here I will get back to it. I took the intake manifold off. All the valves look fine but are dirty as hell! So I think I blew a hole in the side wall of the cylinder 4. And the stock injectors looked unharmed too. More pictures and info to come.
Wasn't the tune that was the problem. It was me being dumb and brake boosting like 15-20 lbs at 2700rpm in second. But kmo43 tuned me I would recommend him to anyone and everyone as he has been a lot of help before it blew and after.
In the spirit of this being a "small build" I would consider some additional parts like timing guide bolt upgrade kit from Mongorat, ARP flywheel bolts(cheaper than stock and reusable), stuff like that. It's the little details that count Good luck man

what bolts are those? last I saw, the only bolts arp offered sometimes had clutch disk interference issues because the bolt head was too big.

These are the ones listed for the opel/Vauxhall 2.0 flywheel but they work. The head is a little bit taller than stock. I think it's only an issue for certain clutches. I know it works fine with ky s3 6puck disc. Clearance can be checked easily by simply putting disc on flywheel after installation to see it they rub. Even if they do rub, it would be worth it to have them modified to fit IMO.
