Sheefa Posted November 9, 2012 Share Posted November 9, 2012 All, I have subsequently found out that the injectors are standard 440cc in my J-spec. Hybrid Turbos are boosted to 1.2 and according to the Austec Dyno are making 460bhp (?) The car is going to Lee P @ SRD on 19th November for complete Syvecs install and I need to know what options I have. Should I stick with the standard 440's and limit boost to 1.2 with a base map? Or can anyone recommend some decent 650 side feed drop in injectors, I assume I will need an upgraded fuel rail and new Bosch or Twin Walbro pump? Could get more costly.......

Geo Posted November 9, 2012 Share Posted November 9, 2012 Plan ahead matey, so depends if your going single in future etc. id go with drop in 800's Bosh044 or walbro 450(lee can supply both) Standard fuel system is enough TCC mode and mapped on the syvecs And watch your face explode when you hit warp speed on that Quote Link to comment Share on other sites More sharing options...
johnny g Posted November 9, 2012 Share Posted November 9, 2012 You don't have to go with a new fuel rail - when I first went with bigger injectors, I had some drop in 800's and they went on a stock rail. I'd get some 800's or 650's if possible. The only alternative then, if you can't get them, would be a new fuel rail and probably some ID1000's. There's always some 800's floating around somewhere.

Sheefa Posted November 9, 2012 Author Share Posted November 9, 2012 Thanks Geo and Johnny - good place to get injectors ? I suppose I'll go with 800's depending on cost. What would the rough duty cycle be on those? Possible overkill as I'd only be going small single when I bite the bullet later on.......maybe! I'll ask Lee to supply and fit uprated pump. Greatly appreciate your help. Greg Quote Link to comment Share on other sites More sharing options...
Rob_Mitchell Posted November 9, 2012 Share Posted November 9, 2012 I got sard 800's in my single build on stock fuel rail and stock FPR but obviously changed the pump... that will work for you too Quote Link to comment Share on other sites More sharing options...

Greatly appreciate your help. Greg on my last car i had 800 drop in's and there was still plenty life left in them, the turbo maxed out before the injectors so 800's are plenty bud, always good to have that little bit extra duty left for peace of mind. you dont wana max them out Quote Link to comment Share on other sites More sharing options...
Nic Posted November 9, 2012 Share Posted November 9, 2012 SH650A Power Enterprise 650cc injectors are a straight swap. Quote Link to comment Share on other sites More sharing options...
Sheefa Posted November 9, 2012 Author Share Posted November 9, 2012 I love this forum. Rob, Geo, Nic and Johnny - thank you. Nic - how much could you supply them for mate? I've got my eye on Siemens DEKA 850CC Low impedance injectors and a HKS fuel rail. Been advised that I'd probably need a Fuel Regulator too?

Rob_Mitchell Posted November 9, 2012 Share Posted November 9, 2012 Keep it simple Sheefa and thats what jamiep said to me when i once was in your boat, stock fuel rail, stock FPR and the drop in 800's plus a bosch 044 pump. Dont waste the money on rails ect its not really needed unless you go BIG power. Quote Link to comment Share on other sites More sharing options...
Sheefa Posted November 9, 2012 Author Share Posted November 9, 2012 Thanks Rob. Appreciate that as yes costs do escalate quickly and I'm not chasing big BHP right now. Thanks again. Greg Quote Link to comment Share on other sites More sharing options...
imi Posted November 9, 2012 Share Posted November 9, 2012 Im running PE650cc Injectos as per Nic's post for the past 4 yrs without issues at my power levels. Quote Link to comment Share on other sites More sharing options...
Guest Budz86 Posted November 9, 2012 Share Posted November 9, 2012 Have a look at the Sard 650's mate, I'm doing pretty much the same as you in terms of setup and that will be my route. Interested in the PE's Nic mentioned though, didn't know about them. Quote Link to comment Share on other sites More sharing options...
Sheefa Posted November 9, 2012 Author Share Posted November 9, 2012 Cost is everything. £700 for Sard 650cc or 800cc injectors off Whifbitz. Quote Link to comment Share on other sites More sharing options...
Guest Budz86 Posted November 9, 2012 Share Posted November 9, 2012 Tell me about it! Im looking for a 2nd hand set at the moment as I don't want to pay £700 odd for them Quote Link to comment Share on other sites More sharing options...
imi Posted November 9, 2012 Share Posted November 9, 2012 Tell me about it! Im looking for a 2nd hand set at the moment as I don't want to pay £700 odd for them if you do for 2nd hand - i would recommend getting them flow tested. Quote Link to comment Share on other sites More sharing options...

Alex Posted November 9, 2012 Share Posted November 9, 2012 SH650A Power Enterprise 650cc injectors are a straight swap. I used these - they drop in and worked well...even with an eManage Blue. Quote Link to comment Share on other sites More sharing options...
Sheefa Posted November 9, 2012 Author Share Posted November 9, 2012 Thanks all and yes Imi will look at flow testing for sure if SH, not worth risk otherwise. Got a few options, just need to speak to Lee about which route to take. Bloody expensive things arent they! Quote Link to comment Share on other sites More sharing options...
Sheefa Posted November 9, 2012 Author Share Posted November 9, 2012 Can someone please confirm do you only need an uprated Fuel Pressure Regulator if running Top Feed Injectors or higher than 650cc? Quote Link to comment Share on other sites More sharing options...
tooquicktostop Posted November 9, 2012 Share Posted November 9, 2012 My advice is plan plan and plan, do it once and do it right, gets very expensive to have to keep revisiting a system that you did not spec up for future power upgrades, I know as I keep getting it wrong Quote Link to comment Share on other sites More sharing options...
Sheefa Posted November 9, 2012 Author Share Posted November 9, 2012 Yes Dean, agreed. Will probably go down the 800 drop in route now given that they're OK for 650bhp. Quote Link to comment Share on other sites More sharing options...
jcbt Posted November 9, 2012 Share Posted November 9, 2012 Tell me about it!

Nic Posted November 9, 2012 Share Posted November 9, 2012 Speak to Ryan about injector size, 650cc is enough to support a 61-67mm single turbo, 800cc would be overkill with hybrid turbos, they'd need to be run at low duty levels which could make them difficult to accurately control.

jcbt Posted November 9, 2012 Share Posted November 9, 2012 Sorry Sheefa - I thought you needed them pronto - may be a while before I upgrade and I know dean is probably not in a rush Quote Link to comment Share on other sites More sharing options...
