Alex Posted April 10, 2007 Share Posted April 10, 2007 Rob they are all pretty much the same...especially when you're only fitting a T61-71... Quote Link to comment Share on other sites More sharing options...

RobSheffield Posted April 10, 2007 Author Share Posted April 10, 2007 hmmm, that would be quite a distance, unless you throw like a girl... lol, yeah, im looking at Siemens injectors with either PHR or Titan rail....not so sure on the SP kit, its a late contender Quote Link to comment Share on other sites More sharing options...
grahamc Posted April 10, 2007 Share Posted April 10, 2007 I must admit, I did spend sometime looking at the PHR stage 1 kit, but the price tag put me... Quote Link to comment Share on other sites More sharing options...

RobSheffield Posted April 10, 2007 Author Share Posted April 10, 2007 I cant see which injectors are used in the SP and Titan kits (They may use Precision ones judging by the flow rates) Quote Link to comment Share on other sites More sharing options...
Nic Posted April 11, 2007 Share Posted April 11, 2007 I wouldnt trust HKS injectors as far as i could chuck em Why? No problems with mine. Pity, as I had a free set here I was going to offer you Rob Quote Link to comment Share on other sites More sharing options...
Alex Posted April 11, 2007 Share Posted April 11, 2007 Why? No problems with mine. Pity, as I had a free set here I was going to offer you Rob I think the HKS ones have had issues due to being stored for long periods of time. Hence they need cleaning, but nothing more. It's the SARD ones that I thought had issue's with their spray pattern. Quote Link to comment Share on other sites More sharing options...
Nic Posted April 11, 2007 Share Posted April 11, 2007 I think the HKS ones have had issues due to being stored for long periods of time. Hence they need cleaning, but nothing more. Same can be said for most injectors really, as you know it's always best to clean and flow test any injectors before fitting. Quote Link to comment Share on other sites More sharing options...

grahamc Posted April 11, 2007 Share Posted April 11, 2007 Actually I remember reading that the HKS fuel rails were a bit of an issue, where the injectors are mounted to the rail. Fuel leaks, etc. Under correction... Quote Link to comment Share on other sites More sharing options...

Fuel leaks, etc. Under correction... I only know of JamieP who had an issue with an HKS Fuel Rail kit, this was a kit I supplied, but I don't know the reason for the problem. I use the HKS fuel rail on my own car and have supplied dozens of others without any issues. Quote Link to comment Share on other sites More sharing options...
Alex Posted April 11, 2007 Share Posted April 11, 2007 Jamie's issue was an installation one. The HKS rail is so common that I think you'd know if it was poo. Human error is the most common cause of kit failure. Quote Link to comment Share on other sites More sharing options...

When moving beyond this HP range we recommend an upgraded fuel system. We have taken our time and put together a kit that will flow enough fuel for 700+rwhp. If you are using the VPC, then you will need the 720/680cc version, which works fine with these injectors. This kit is designed around the PROVEN twin Supra fuel pump (in-tank) kit. We are now utilizing the incredible Titan fuel rail with twin end feeds and a single center return for maximum efficiency and reliablity. Included are the following item's: Complete kit Fuel Rail 720cc Injectors x 6 (complete) Aeroquip Fittings Aeromotive Boost Fuel Pressure Regulator (FPR) Braided lines and Aeroquip fittings Additional Supra Pump (couple with your existing pump) Twin in-tank fuel pump kit All connectors, pre-cut wiring, instructions Relay The most complete fuel system on the market, at the greatest value to our customer. Sale price: $2,195.00 ------------------------------------------- PHR Stage 1 The Powerhouse Racing Fuel System is the highest-quality and most complete fuel system available for your Supra in the aftermarket, period.

Our fuel system upgrades are pre-assembled in the box, and are ready to install without any special tools required. The PHR Stage 1 Fuel System includes the PHR 17.5mm (-10AN) ID high-flow fuel rail, twin Walbro GSS341 in-tank fuel pumps, Aeromotive EFI fuel pressure regulator, liquid-filled fuel pressure gauge, fully assembled and pressure tested -6AN Stainless Steel braided fuel lines, hi-flow fuel filter, Siemens 720cc fuel injectors, PHR quick release injector clips, and all hardware necessary for a complete install. We even include a sheet of a space-age polymer used to wrap the fuel pumps to prevent magnetic interference. This is the perfect fuel system upgrade for customers needing to support between 550 and 700 Rear Wheel Horsepower. A complete and high quality fuel system upgrade from the most trusted name in Toyota and Lexus performance. Price: $2195 ------------------------------------------- PHR Stage 2 The Stage 2 Fuel System includes the very same components as Stage 1, with the exception of 850cc Siemens injectors.

I use the HKS fuel rail on my own car and have supplied dozens of others without any issues. At the end of the day, I have one supplied by you, in my car now. Thats the full HKS kit, with a Walbro fuel pump. Quote Link to comment Share on other sites More sharing options...
wkdtime Posted April 11, 2007 Share Posted April 11, 2007 I'd go for a full fuel kit over modding the stock rails etc on a single Turbo conversion. Injectors, 650's minimum with a T61, 720's with a T67. Quote Link to comment Share on other sites More sharing options...
JamieP Posted April 11, 2007 Share Posted April 11, 2007 I only know of JamieP who had an issue with an HKS Fuel Rail kit, this was a kit I supplied, but I don't know the reason for the problem. I use the HKS fuel rail on my own car and have supplied dozens of others without any issues. The issues with my rail turned out to be because it was bent i brought another and that was fine.
