      What you see there are 1.8T/R32 injectors. The USRT Mk4 24v injector is pictured below. Details will go up on the website shortly. Mk4 12v parts have been designed but not produced as of yet. [IMG]http://**********************/smile/emthup.gif[/IMG]

      Hey Scott hows it going? Im interested in some injectors for my forced induction project on my 2.0. The motor is stock. ive lowered the compression and run 93 through it. I want to run 15 psi and was wondering what size you would reccomened. I was thinking of 440cc at 4bar. but im no expert. Right now i have for fueling a eip afpr. stock injectors. stock pump. and an eip stg2 eprom. i plan on going with c2 once i get the injectors i need. If there any other specs you need let me know. Thanks.

      How much power are you actually trying to make? Pleas specify whether you mean whp or bhp. With that number in mind I can guide you on a fueling solutino. Manifold pressure is more a reflection of flow restriction than anything else.

      I want to make close to 220whp. and i was also looking at your manifold you sell. since it would be alot better than stock. plus i seen the stock numbers it put down. wondering what it would do with forced induction.

      Yep, the Bosch 440cc "green top" injectors will be a good idea for you. They're a touch larger than necessary, but you'll be able to push that much harder when you get bored with the 220whp. As for the USRT crossflow intake manifolds, we're not sure yet what the gains will be with boost. However, with 16whp+ achieved on a normally-aspirated engine... a boosted set up should really be outstanding. Be the first to share some big numbers.

      Hey Scott, I have a question about Fuel Injectors. I am about to put a GT2871r turbo kit in my 2004 1.8T Jetta GLI.
      I currently have a 4BAR FPR. I wanted to know which injector would you recommand.
      I think that the turbo setup require 440cc. I wanted to order Bosch 440cc injectors but I need to know which one would be better so I don't run too rich!
      Thank you

      The Bosch 440cc "green top" injectors are not ideal for a 1.8T application -mostly for spray pattern reasons. You can read all about this issue on USRT's injector page. Click on the video links and you'll gag when you see the Bosch 440cc spray pattern compared to what it is supposed to be.

      A far better way to go would be our new Genesis injectors which emulate the OEM spray pattern. The factory engineers took special care to avoid hosing down the intake manifold and cylinder head. To my knowledge USRT is the only company currently offering an injector with these features built in.

      In your case, I would recommend the 380cc injectors. Run them with your 4bar fpr and you'll get the 440cc flow that you need. Compared to the Bosch 440cc you'll get sharper throttle response, easier cold start performance, will eliminate the misfires, and probably some added low-rpm torque. Idle will be smoother, too.

      Fuel Pump arrived today [IMG]http://**********************/smile/emthup.gif[/IMG]
      Will call when ready for the lines and fittings
      Thanks again

      Do you carry the Bosh High Performance Fuel Pumps? I'm looking for a good fuel pump for about 14 psi on a C2 Software run Supercharger(V-1 Vortech) kit do you have any sugggestions?

      hi Scott i have been checking your site out and, if you have time, would you answer some questions for me? i just purchased the ATP stage two turbo kit for my 96 ABA 2.0 and i would like to up the boost from the 7 psi that the waist gate is set at. to make more boost i have an ATP manual boost controller. i have yet to install the kit. i also ordered ARP head studs and a Eurosporttec adjustable fuel pressure regulator. should i upgrade my fuel injectors? would the chip provided with the kit work with bigger injectors? for smog requirments i would like to keep the factory computer. what are my options? thank you for your time.

      Wow, I haven't gotten a notice from Vortex that there were any messages in this thread. I apologize for taking so long to get back to you. Now, on with the tech talk. [IMG]http://**********************/smile/emthup.gif[/IMG]

      Yes, we have the Bosch Motorsports "044" fuel pumps available. They are strong enough for about 600hp. So, your application will be no problem at all. Btw, The website doesn't mention it yet, but we are now offering the fittings for these pumps.

      Let me know how much power you're trying to make and I can calculate a proper fueling solution. (Boost level is only part of the story and doesn't factor in directly because it is really just a measure of intake flow resistance.)

      No, software is written for specific fuel injector flow capacity/fuel pressure combinations. Slight adjustments may be adapted by the ECU, but if you go with a significant increase, you will certainly run rich.

      There is no direct swap available for this engine. However, if you're willing to change injector electrical connectors and can live without your air shrouding, then there are 315cc and 380cc solutions available.

      I've test fitted some stock 1.8T injectors in my '02 AZG 2.0L.
      The 1.8T injectors are 6mm shorter and the manifold end o-ring
      is slightly smaller preventing a good seal.
      I have a 1.8T injector wiring harness in hand.
      Do you have ~317cc - 380cc injectors that don't require modification
      of the fuel rail or manifold seats?
      Thanks, Rey

      hey scott, maybe a supid question but no one else can answer it. i have a 97 obdll 2.0 and im putting together a turbo system for 6 psi max. Can i trick the stock computer by putting bigger injectors in(greenies) and just having the computer learn that system? Stock ecu, stock fpr, bigger injectors. Im gessing 150-160 whp max.

      Scott, I have a 1.8t w/ k04 001 running on revo 4 bar, My Revo dealer reccomended i upgrade injectors and fuel pump. he also reccomended the USRT product by name, i was wondering what injector/ fuel pump combo i should run, i dont want a Rube Goldberg setup, im looking for the BEST solution. the car is a daily driver
      my intake setup is front mount intercooled, 2.25 piping, stock head and intake manifold all hardpipes
      the exhaust side is K04-001 3"down pipe -cat 2.5" resonated and muffled mandrel bends
      Id like to make 230 whp. i know its bold on a k04 but.......

      I apologize for the lack of responses, guys. Vortex's auto-IM function doesn't work most of the time now, I don't see when questions roll in.

      For that kind of power, I'd look hard at some Genesis 380cc injectors which are a direct fit and have the OEM spray pattern. Basically, they're like copies of the TT225 parts, but for <2/3 the cost. As for the fuel pump, I think you'd be on the edge with your stock unit. So, my recommendation would be either a Walbro inline or a Bosch Motorsports. Go with the latter if you'd like to keep things a bit quieter.

      1.8t AWP in question:
      anyone switch from Bosch Greentops to Genisis 415's yet? From reading it seems like a good idea. I get all the common crap that are associated with Greentops. Just wanted to get some definate updates. Thanks

      I was looking on the USRT site and it say there is a version for the AEB and non AEB. Assuming that injectors go into the manifold I can assume that this only applies to cars with an AEB manifold? Or am I still off. Im going to be using an AEB in place of my AWP soon, that why I asked?
      AEB head I mean, not the whole engine and will still be using the AWP manifold and fuel rail and stuff. I need to know this soon as I am ready to order a set. I have emailed your site address as well. Please let me know. Thanks
