mabye next winter ill do the bottom but for now im DONE dumping cash into her

 

So is there an advantage to getting the 750s rather than the 440s, besides the lower duty cycle. Will the 440s fail faster then?

 

440s can push less fuel....SO you need to know how much youll need. Since i wanna do this once and do it right i over did it now so theres room for improvement, plus they are high impedance so its just plug and play in OBD1

 

Famous last words.

I hope you have at least a 255 lph LP pump for those injectors. Since you're planning and getting over kill stuff (like these injectors), I'd get the Walbro 255 lph HP pump. I had to upgrade from the LP to the HP because I didn't plan accordingly. Just a suggestion...

It's all about what you're planning to do. If you're going to run lower compression and higher boost, you'll need a high CC injector to compensate for the amount of fuel you will need. The lower the compression, the more fuel. The higher the boost, the more fuel.

Your question is the same as saying "why not stick with stock injectors instead of getting 440's?" It's all about how much fuel you need.

 

i do have the walbro 255. just installed that last wekk. kinda easy too. took the rear seats out. poped the trap door raised the pumped and droped the new one!

 

There is a difference between the 255 LP and HP though. I was running RC 650's with an HP...

 

The HP is probably overkill for a stock bottom end boosted setup, though. Get some forged internals, turn up the boost, and the HP should be plenty.

 

I'm saying for future use. 750's aren't overkill for this setup? :thinking:

I thought I'd be fine with LP, too. But... we all know how that went.

 

Touche.

 

ummmmmmm.....i dont know how that went
could you please tell me how "THAT WENT" :noes:
how do you know if its LP or HP?
