what supporting mods do you need to make 520/530 with a 7064 mark? Would an engine with standard ports but bigger inlet manifold and uprated inlet cam make this?

477hp is most I have seen on a stock engine and a hart inlet. I did one with cams but the owner crashed the car before I got to see what Hp it makes.
On a ported head and cams I have seen 521hp and 535ftlb.

I would run 83’s if going for around 500hp.

You could always fit 72’s and have it mapped then see if they are still fueling enough?
if you do max them out just drop the boost back a bit until you can get hold of 83’s

I have Siemens Low impedence 83lb injectors in my 2wd Saff. I had to change to an L8 ecu with a MSD driver baby board. To run any of the modern high impedence injectors you need an up to date ECU.

what's a progamapped ecu?

have you actually tried running high imp injectors on weber marelli or are you just guessing?

most ecu's designed for low impedance injectors can happily drive high impedance injectors just fine.

From: normally at work

I fancy a BW 7064 on mine once it's up and running again but will have to wait as spent far to much money on it already this year with management, brakes, and wheels.
My only worries are cracking the block as I have the ARP stud and nut kit fitted and don't fancy an engine build just so I can change turbo so need to investigate this more.
