i,ve half stripped my 2wd engine down after running stage 3 with rs500 intercooler and t35. how much more will this block take should i keep this block or start off with a 200 block with the view to more power later on

 

mate run low compression pistons it will handle the power

 

I think after stage 3...most ppl go up to stage 4 lol jk After a stage 3, tuning can take so many different routes to acheive the same goal. Choose 1 route and stick to it, dont mix and match different tuners methods...it wont work long term. But low comp is deffo gotta be part of your next step...need that with this countries poo fuel octane rating

 

4x4 pistons to give lower slightly lower comp and ported head with cams,greys and remap
Should be knocking on the door of a nice useable 400bhp

 

Get propper advise from an engine builder/mapper but do all the work yourself

 

Err stage 4! t4 turbo bigger boost, bigger injectors new map etc etc

 

^^^^ copy cat

 

As others say, there are lots of options. It depends on your goal.
I believe >400bhp means porting/flowing the head, and more then >430bhp or something also means other inlet/outlet cams (BD10/14) I think.

It probably also depends on what you're renewing when rebuilding (all new ARP bolts for big power, big end ald main stud; high pressure oil pump; good headgasket; 044 fuel pomp for more flow etc.)

Good luck
