I was thinking about that also, but I still don't have the car in the garage to start ripping things apart. I'll probably try it without redrilling first. If there's a problem, I'll just drill them later. As long as there's nothing interfering with the spray it shouldn't matter if the injector is sitting back away from the valve. If anything I'd think it would help by not spraying on the valve and port as much when the valve is closed.

 

maybe this one slip by us all. isnt the 944 turbo just half a 928 engine cant we just us that fuel theres 951 guys running 72lb injectors.

 

On the 32v cars, you can use Ford injectors in various sizes... And they are much cheaper than what the 951 guys are running... Hmm, I wonder the differences in the 8v 928 vs. 951, and 16v 928 and 16v 968 injectors are... Anyone know? If you swap a whole fuel rail out with injectors, wouldnt you just (assuming it bolts up) just have to have the right impedence on the injectors for it work? Say, run any type of fuel rail, like honda, ford, whatever, as long as the impedance was right and it was made to bolt up?

 

Oh, and that 61 turbo is a good one... I'd love to run something like that on my 951! The turbo in my avatar is probably going to be a little big...

 

hey barry.....what kind is that turbo in your avatar? i could have put together a kit really fast and easy but i want to "bult it once built it right" for upgrade and tuneabilty. so i can expand. and i will have a system in place to handle and tune my 5.0 liter 951 piston (teflon coated) engine. that i will boost until my tranny gives. i think on my 4.5 plane jane. will make about 400 rwhp at 12psi. and my built motor i'm pushing for 600+ i'm taking no prisoners. i'm going with a high grade turbo from the start be cause it will get me my power smooth and with out braking a sweat. I have access to a dyno, race gas, 9th injector and installing water injection. so denotation is not my worries.

 

glad my ob only has 8.5:1 (really like 8.0:1) compression ratio. and with some bas **** cams from get do. with a 9th injector under WOT or Bwahhh. i think 8 psi with water injection to cool is safe

 

The turbo in my avatar is a T4 .70 A/R P-trim... Its frickin' huge.
Sounds like you have your hands full! But, keep us updated :^).
I'd like to see if anyone responds to the fuel rail and injector question I posted....

 

re: 951 injectors - I looked at the 951 injectors at one time, and the impedence is wierd - can't recall the exact ohms, but not low and not high (which leaves what...). The rails *should* fit the 928, and they are clip style, not barb. Could be clearance issues on the rail to intake, I have not mocked it up, but injector hole spacing should be good.

which fuel rail has the better potential for larger injectors

 

what is the exact l-jet or lh-jet commponents i need to convert my cis shark over. looking to start finding these parts to go EFi and megaquirt

 

I think at least the runners and the plenum/TB. Maybe some custom fuel rails. MS will use a TPS with a full metered swing instead of our click TPS.
Then you will use MAP and IAT. The map on MS is IN the computer, so you would just run a vac/pres line from the manifold into the car. IAT can be bunged onto the intake manifold somewhere. I was going to use the front where the larger hole is on the spider body, but I sold that 2V engine.

 

I have done this before running 3 different systems. Haltech, Electromotive tec II, then upgraded to a Tec III.

Basically you need EFI flow tubes, plenum and TB.

Custom fuel rails if you want to run normal o-ring injectors, IE no hose at the top of the injector.

To that you can add some Aeroquip SS braded hose to make it easier.

Global express fittings make a metric to JIC compression adapter. You have to cut the metal fuel supply line and return line and these just slip on and tighten up.

I am assumming your main rubber fuel supply lines are dry rotted anyway.

 

Oh yes, I modified the 928 TB to a GM tps, so that is something else to do. I used a D internal tps.

Thniking back now, I think I only bought flow tubes.

 

wont a s4 fuel rail fit? or is it cheaper to have a custom blank and make my own?

 

Its no t cheaper, but it may, in the end, be a better idea.
