View Full Version : Aftermarket Injector Question

05-08-2002, 05:32 PM
I am most likely buying some Apexi 550's a friend just picked up if he wants to sell them cheap enough but I wanted to know if there are some US companies who can sell injectors for cheaper then most the prices here in Japan.
I have seen somethings like "quick shift" kits REALLY cheap in the states and in Japan they are close to $250.
I wonder if injectors would fall into the same category. Heard of RC Engineering, i heard they can make the sidefeed injectors 550cc but never saw any kind of pricing.
The common cost in Japan for good 550cc sets are around $450+
I will need these soon for im doing a big turbo install soon and need the fuel to be on par.

Hey.. the words "Cheap" and "Big Turbo project" don't mix! If you are serious about going turbo.. I would say either get a custom Fuel rail made, or get a JWT fuel rail for Top feed injectors. The side-feed injectors are expensive.. and ultimately.. you will end up changing the stock fuel rail anyways.. so get the Top feed from know. Average price we sell injectors of MSD or Rochester "who makes" MSD injectors... 550cc -850cc from 85- $105 each. And while you are at it.. go ahead and get an adjustable fuel pressure regulator/w gauge one time. This will save a lot of tuning and idling headaches in the future. http://www.freshalloy.com/

Oh yeah.. I forgot..a good place to look for your Fuel needs... www.force-efi.com (http://www.force-efi.com) He's pretty cool of a person too! And a good modification list for your turbo project.. www.back-yard-productions.com (http://www.back-yard-productions.com) http://www.freshalloy.com/

well what I meant by cheap was, he is selling the sidefeed Apexi 550's at $350 for all 4. They are brand new.
Actually you hit on something I have been thinking about doing, the top mount injectors.
The prices you are talking for injectors is really good I think, now I would have to find top feed fuel rail, regulator for SR to go along with it.

You can get VERY large (flow) top-feed injectors from PTE ... Delphi 95 lb/hr (997.5 cc/min) low-impedance injectors for $75/ea, or Bosch 160lb/hr (1680cc/min) for $90/ea (!!!).

They have other sizes too.


Yeah...definitely look into sources for domestic car performance parts.

****... $350 for all four! That is kinda hard to pass up.. even if you change to Top feed later.. you can always find a sale for the rail and injectors complete! Well, for that price.. another route you can go.. is to have brass fuel fitings welded on your stock side-feed rail... which you can bolt on an adjustable fuel regualtor.. and bigger return and inlet fuel hoses.. like -6 and -8. http://www.freshalloy.com/

good ideas.. its making my imagination wonder, hmm.... People look into the JDM market so much for stuff but there is a huge market in the US for tuning parts and its cheap.
Just like I have a GTR fuel pump but after researching these Walboro (spell?) and other electric pumps I see they flow alot more for less money.
asad- nice prices on those injectors too!

the only thing im concerned about with switching to top feed is the connectors off the wire harness.
Also, with going to the inline style pumps, I would have to figure out eliminating the current in-tank pump. Never done that before, would be venturing into new territory.
However, its not really important because the GTR pump will do fine for the power im aiming for. My goal is no more then 350hp, its not a drag car, its a drift/circuit car and 300 is perfect. I allready have 250 at the crank, but thats running extremely lean, i know with my current set up I could get 250 to the wheels. I just need to get a Power FC commander unti so I can adjust ****, I also need to dial in my cams.

<font size="2" face="Verdana, Arial[/img]No kidding. Some people go for JDM just because it's JDM. Others do it because they don't do the research and realize what's out there.

<font size="2" face="Verdana, Arial[/img]Here, you can actually get the appropriate injector harnesses at an auto parts store. Most of the "domestic"-style top-feed injectors (MSD/Rochester/Delphi etc) use a standard Bosch connector. I got the connectors for my MSD's at AutoZone...I think they were listed under a 2.0L VW Golf. You can just splice them in.

Asad, clever idea. Do you think the VW fuel injector connectors would fit on a sohc? Mine are currently pretty corroded and I don't want to pay dealer price for some OEM injector connectors.
