So I've been under the impression that, shooting for 200whp, I should go with 42# injectors.

I just re-read the section of Maximum Boost that talks about injectors, and it appears as if I could get away with something smaller.
It says that:

pounds of fuel per hour per injector = (expected bhp * 0.55) / number of injectors

So, saying 250 bhp just to be safe, I would get:
(250 * .55) / 4 = 34.375 lb/hr

Terminators came stock with 39# injectors, and I bet I could get them for a lot cheaper and easier than green top 42# injecotrs.


Does all this look right? Will I be safe going with 39# injectors instead of 42# ones?

 

450's are $5 a peice in da junkyard and will support almolst 300hp, just roll with the 450's, tested and proven by hmt's finest

 

I totally would, but this is for a Focus, not a Honda. I need high impedance and a certain plug style (Bosch EV1). At least I think it's EV1. It's either that or EV6. Either way, I'm pretty much stuck with buying injectors that came off of Terminators and Lightnings or injectors made for Ford vehicles.

 

top feed or side feed?

 

you ever ben to focaljet ??


how are you going to control these bigger injectors ??


talk to kamilk69 on here he seems to know his ---- when it comes to a turbo focus

 

Yes, I hate those ******* over there. Way too many of them are, "No, don't do it yourself, spend $4,000 on a kit and pay somebody to hold your hand and install it for you."


I'm ordering a chip from JMS chips once I've collected absolutely everything else needed for the build. I'll tell them what I have done already (just a 65mm tb) and what every single component of my turbo setup will be, and they'll make me 3 tunes.


And, yeah, I've been talking with him a little. He's helped a lot so far.

 

I think I may have found some green tops for $75, which is doable and actually a steal for those things, so this thread might be moot now.
