I think I've done enough research to narrow the choices down to 4 options but would like some input about it.

'96 Z28 A4 with a p600b, pretty much stock right now but I want to be able to run the 12# pullies later. If I hit 500rwhp I'd be happy anything over would be great. Not sure what the limits of this setup will be.

Choices:
1. 42#delphi or svo's (Alot cheaper but I'm afraid they might be borderline to small unless I can get away with bumping the fuel presssure up.) $250-290 for injectors + $70 for an afpr kit

2. 60# mototrons (Don't really mind spending the money as long as they will idle good since they are on the large side) $440

3. 50# Precision Turbo injectors http://cgi.ebay.com/ebaymotors/ws/eB...RK%3AMEWA%3AIT
(Anybody running these? Seems like a great deal and should be about the right size. Are these the Delphi ones that are hard to tune?) $328

4. Low z ?# (Have not done enough research yet but I do know they are expensive enough to set my project back awhile longer) $800???

Open to any more suggestions or input keeping in mind I won't be changing out blowers but a 383 isn't out of the question when it comes time for a rebuild. thanks

 

i'm very happy with these put them in last week.

Flow matched, nice price, plus they sponsor the board I think.

 

I have some Lucas 42.5's I have no use for, if your interested.

Shoot me a PM with a price, location, info on them if you would please.


radik - Thats the ones I'm leaning toward since they should cover anything I'll ever do.

 

42's should handle 500hp easily. I went up to 542 with them, but they were pretty much maxed.

 

What's your car's flywheel hp? 60lb isn't too big?

 

What fuel pressure are you running the at? That would save alot of money and seems like it would have more control at idle than the 60s

 

I'm running them at 43 psi, i just switched from 42 svo's running at 50lb.
No they are not to big stable down to .7
