You may as well get the kit:
http://66.216.67.51/product.asp?0=211&1=333&3=578
Jason has provided everything in that kit that you'll need to run 1600cc injectors (besides the ECU that is).

Kinda pricey yeah? Doesn't one of the other members (Rxrotary2 7)offer a kit with both rails and both sets of injectors, and a FPR? All that needs to be added is the pump. Maybe his doesn't have 1600's but 900 bones is alot.( the other was around 6-700) Nice kit though. Not bashing the store, just my 2 cents. Aloha, Dave

I don't know if Keith has a full kit or not. I'm sure he'll pop in and let us know. If not, I'll PM and bug him to find out.
As far as Jason's kit, it's complete:
1600cc injectors
Fuel pump (if you are upgrading your injectors to 1600cc's, I can't imagine using the stock pump)
FPR (same thing as above)
Fuel line and fittings
Resistors (needed to run these with the PFC)
etc...
Looks like a good deal to me.

Yeah I agree but Keith's has a new primary rail and injectors as well if I remember correctly. I guess it's a mental insurance thing for me to replace both with new units when building a nice(HP) engine. BUT: with the cost of a pump added in it will be the same or more than Jason's. ... So it's a toss up i guess. BTW: I agree about never trying to go with 1600's on stock pump. (Can you say overworked) and the fpr! Both kits look nice. It's worth it I am just comparing the other options. Aloha.

well what im going to be doing is putting the 850cc from the secondaries in the primary rail (common) and get the new rail and put in the 1600cc, but my question is if that rail is good, seems like it is.
let me know mahkjik or anyone else with experience with it.

Jason's kit is not a bad price, and my kit offers different components than his. you cna see some here. http://www.kgparts.com/

i cant see how this wouldnt work. the stock 550s are taller, so by milling down the rail to fit, you have a perfect seal. correct me if im wrong.

what i want:D
400-450, maybe more, we will see how things are with that, but that is what im shooting for. is the whp a factor on how well the injectures seal? well i guess if you run more fuel causing more pressure then its a problem, more feul more power? am i correct?
with the new fuel rail will it accept all 850 injectors?

well now thats not good. so that means that ill have to either get 2 things, maybe even both.
the bigger primaries or fuel pressure regulator.
bigger primaries are a pain though cause they mess with your idle and regulator is like cheating, and can cause problems if you go over 60lbs.
does this sound correct?
jason i see that you have 1000 primaries, is idle litttle weird at times?
tell me what i should do guys, i want to run safe but powerful, not that they mix to well but fuel wise at least.
thanks

Using a fuel calculator 850cc primary and 1600cc secondary should support 670 at the flywheel. Im guessing that is on a stock motor. We are running large street ports or race ports. The car we were tuning, I think the fuel pump was not holding up which could be part of our problem. The A/F was in the low 11's high 10's.
My car idles great with 1000cc primarys, but it does take a few cranks to get it started.

well i am planing on porting, but not to big, i still want to be able to pass emissions, but still have bigger than stock ports.
so do you think i will be fine with that 850s and 1600s? also maybe a upgraded fuel pump? i dont want to run anymore than 80% duty cycle. let me know what you think (and others of course) what is the safest way to go with the fuel system, best pump, size injectors,etc.
thanks

On my T 78 I ran 850's for primaries and 1600's for sec.. XS modified the stock rails for the bigger injectors.( this was about 3 years ago) I used a Paxton FPR and don't recall the pump that was in there. I was dynoed at 401 @ XS's dyno.( again about 3 years ago) Stainless lines from the firewall to rails. IMO: it looks like crap with the welds for a stainless fitting on the ends of the rail. I am looking for a nice set-up soon. Both of the ones mentioned in this thread are looking good to me.

Just have him call me if he needs that setup. I have everything except the fuel pump.
