If you have switched to EFI, could you please state which fuel injectors you are currently used, and/or have used in the past.


I have "Ford Racing (or Motorsports) Green Top 42 lb/hr" Injectors. They are high impedance.

Link:http://www.ebay.com/itm/FAST-INJECTOR-FAST-SINGLE-42-LB-HR-441CC-MIN-304200-/370576046540?hash=item56480db9cc&item=370576046540&pt=Motors_Car_Truck_Parts_Accessories&vxp=mtr

However, with some recent changes I will be switching to these:

http://www.ebay.com/itm/660cc-Honda-Civic-Integra-Turbo-D16-B16-B18-H22-Fuel-Injectors-JDM-D15B-ZC-VTEC-/200722454007?hash=item2ebbfd95f7&item=200722454007&pt=Motors_Car_Truck_Parts_Accessories&vxp=mtr

They have a longer nozzel which will sit further down in the injector port and are larger.

On my Gulf I use Siemens Deka 630cc @ 3bar "pencil"-type injectors, on the red 924 I use 480cc (?) injectors from Mazda 323 GTR Turbo.

I'm still gathering parts and making decisions so not decided on injectors yet.

The injectors you linked to on ebay look a good deal.

I was also thinking of going with the Siemens Deka 630cc pencil injectors - they're supposed to atomise better and be reasonably easy to tune at low loads/part throttle etc.

I'm using Denso 565cc blue tops (slim line) with a machined head to drop them into the air stream. They are from a 2010 Subaru impreza WRX. No problems with low speed drivability - it's better than the CIS by a million miles!

Ps mine are run at constant 3bar since they are over specced for my needs but still keep good atomisation. (think they'd do 300hp if needed)

If advise modern injectors - they are said to be light years ahead of old fashioned ones. Maybe get a refurb too if they're used - budget £50 for 4 in UK.

Hmm, you guys are using injectors with a quite high flow rate. Off course you have Turbo engines, but still.....

I'm gathering stuff on Ebay, for my EFI project (N/A engine). I'm not looking for any major hp gain, well a little would never hurt . The primary goal, is an engine that fires up and runs perfect every time I start it. My old Golf 3 with a 1,4 engine (bosch monopoint injection) was always a pleasure to start, cold or warm, and I would like the 924 to be just as delightfull to fire up.

I have these injectors on my list.



Bosch 0 280 150 779, 192 cc/min (used on the Volvo 850)

I like them alot, since they have a nozzle, that can go into the deep CIS injector holes in the cylinder head.

Opinions ?

I use Bosch 0280158040 with 24mm extended tip/nozzle from the Motorsport E14 series. 980cc should be enough for E85. Single 30° wide conical spray pattern. High impedance.

havent done the EFI conversion yet but i have 8 used injectors from the 454 build i did on my suburban. they are high flow rated 65 psi i think.
there is a shop that charges $15 per injector to clean them with a next day turnaround. that is if they fit

To avoid the fuelrail clearance on the 931 chargetube, I'm looking at "stubby" injectors like these:
http://www.ebay.com/itm/Siemens-60lb-hr-Fuel-Injectors-Fit-EV1-Bosch-Short-Stubby-Pico-630cc-Mototron-4-/330855501202?pt=Motors_Car_Truck_Parts_Accessories&hash=item4d08864d92&vxp=mtr

Does anybody know if they'll fit in adapted inserts?
