My D-series has an old JDM 88-91 Head..
prelude injectors
ebay turbo kit... manifold, piping, wastegate, blowoff.. etc...
chipped and tuned
stock fuel pump

I'm want to get:
better turbo, manifold, wastegate, blowoff
smaller piping
bigger injectors
better fuel pump
s300

I'm not sure if keeping the old JDM is just as good as the original y7 head?

I want to keep cost down as ultimately I'm saving up for a B-Series swap
but I would like to have some fun with this SOHC before until I can afford a swap...

Any suggestions on parts with website link on where to buy a decent pricing would be much appreciated
OR perhaps you have some parts you'd like to get rid of... let me know...

Thank you for your time

 

If you're saving for the B-series swap, then stop putting money into this build now, and just save for the swap. There's not way you're going to get that kind of request fulfilled here. H-T members aren't your personal shoppers.
