im getting:

evo3 b16g turbo
evo3 exhauast mani
fedanza cam gears
eagle rods
clevite bearings
greddy fmic
ross pistons

i still have the 190 walboro on, do i need to upgrade to 255?

Also should i upgrade to 720CCs ???

560cc off an EVO will be good for around 21 psi. i don't think you need the 720s unless your planning on a huge turbo.

 

[v2ner]

oh yea, that pump is fine.

 

[GSX6bolt]

So keep the 190? Can i get the 620ccs jus to be safe down the line? That wont hurt?

The 190 will be fine for the 560's, and if you can keep your IDCs down on the 660's you should be fine with the 190 as well. If you do manage to push the 660's to above 85% you will most likely need to at least rewire your fuel pump to 14v in order to keep up.

 

[GSX6bolt]

Well im not rewiring. 255 doesnt cost much at all.. Ill go with that...

But i was asking should i upgrade to 660ccs?? THey cheap as hell too, i dont see any hardm in it.

You should be fine on a 550cc injector and a 190 pump the 255 really is over kill for 99% of the guys on here.

Yes.
And buy some NGK BPR7ES plugs or you'll run into problems.
With a 255 lph fuel pump you will also need a AFPR.

But you think 660cc are overkill on a 190 walboro? Whats wrong with 660cc?

Need those spark plugs then...

Unless you plan to go bigger then a 16g the 550cc injectors are fine.

Awesome, thanks

leave your 190 pump go with the 550's and use ngk bpr7es plugs any you will get good for like 24psi.
