Possible power? R33 rb25det

[Zeeable]

Hey everyone,

I've made a post about this already but wasn't very direct and also my build notes weren't very readable 🤣

Just wondering on the possible power this could make?

It was an auto which im 95% of the way to collecting manual conversion and im also thinking of putting a link g4+ ecu in it for better tuning.

Appreciate any info as im new to cars and learning still!

Limited by the injectors to about 750 engine HP on 98. Much less on E85.

If that Pierburg pump is the main delivery pump, then...maybe that will be the limit. Although probably not.

Too easy thanks mate. I was thinking about getting 1000cc injectors, want to push it to 750bhp in the future. Should i go bigger than that?

The walbro is the main, the pierburg is the pump for surge i believe. 

Previous owner also said it had 2x300L pumps so not sure if it was upgraded since notes were written.

For 750 you’re going to need at least 1650cc injectors and another one of the walbro fuel pumps

Too easy cheers mate. Anything else i should be looking at? Bigger intercooler, etc.
