Poor little guy

clearly someone hasnt seen a stroker engine, iirc GTMs 4.5L stroker kit makes 490hp so that is about 380-400whp n/a

Haha! Brilliant thread. All it needs now is an explanation of twin charging.

Tapatalk & such etc

Better yet how twin engines work

I wish I could afford the GTM stroker:shakes head:

Hey, I like that new Fast Intentions turbo manifold prototype though:happydance:

Hmmmm I thought 500hp was the cut off point for stock... I will research this further and report back! :tup:

I've never heard of a z goin fi and keeping stock pump and injectors

This is not true the injectors and fuel pump must be upgraded when going F.I

:wtf2: soooo........ We can build bunk beds?

Second that, I dumped a SC on mine and had to change pump/injectors.

Meh, I'm wrong. Sorry for the bum input.

What size are the stock injectors anyways? 380-400ish?:confused: IDK I bet 525's would be okay for FI

The lowest I've seen is 600

600's are just over stock and are required when going FI or even higher.

If you went with a stroker kit you would need to go to 600's as well to adjust to the larger volume of displacement. as other have eloquently put it: More Air = More Fuel... stock injectors are in the 400-500 range.

As far as fuel pumps it is recommended to go to a 255lph or even DW300/330 for even better consistent flow to the injectors.

Also think of spark plugs too... More fuel needs more spark ;)
