Hey guys I just bought a darton sleeved h22 block and I’m trying to get advice on drag setups..

I’m currently running a jdm h23a on a td04e turbo witb a log manifold (running out of turbo in high roms). I’ve got a Quaife lsd, insane shaft axles aem fuel rail blox 750cc injectors and walbro 255 street tuned on s300. Suspensions stock and stock wheels with BFg 205/55/16 drag radials.

Anyways…. My turbo was too small on this setup so I bought a precision 5831 76 trim 58 mm turbo. I also have a darton sleeved block I’m looking to get about 500 hp out of I think. Will my current setup support this if I get pistons and rods? I assume I may have to upgrade my exhaust manifold at the very least. I’m looking for ideas on what I can use that I currently have and what I need to upgrade. How high can I rev the stock head with springs and retainers? I’m trying to keep this somewhat budget friends 3 grand maybe ontop of what I have in it already
