When I'm boosted do I have to upgrade injectors? If so how big can I go before upgrading injectors? Thanks

If your boosting at all, better go ahead and upgrade the factory injectors. 450rwhp is close to maxing out the factory ones on the cars I've seen. Seiman deka 80# are a good set that work well for all of us and don't break your bank account.

Stock injectors max out long before 450whp on a boosted setup without a 1:1.

Another recommendation for Deka 80s here.

i think the stock pump is limited to about 500hp, so yes id get a bigger pump. im not sure how far stock lines and rails will take you though.

Yeah I might as well do them to if I'm doing pump and injectors just trying to get everything ordered man it's starting to add up lol

A walbro 450 and 80#s made 690 through the auto on mine. Pretty easy upgrade too

tylc557

Yeah that more than I'm shooting for what's your set up?

JoeNova

I have a pair of 340 lph pumps and deka 80s. Made more than 700 wheel on a stock 5.3 with a small cam. I'm only barely into the realm of needing that 2nd pump too.

You can get a Walbro 400-series pump and Deka 80s for less than $450 shipped to your door. Injectors are $320 or so and pump is less than $150. Together they're good for 800 at the wheels on a normal gas setup.

Are you boosted nova?

JoeNova

If I'm making more than 700 wheel on a stock 5.3 without boost, I'm a wizard lol.

tylc557

Lol I was wondering you said 700 with just fuel mods but I figured you were so what tranny are you running?

JoeNova

4L80e. Stock 150k mile. No rebuild. Just a $120 transgo kit.
