Does anyone have a diagram or pictures of all the components to a c2 turbo. I wanted to Upgrade my fuel system and was curious if they had a fuel rail and what size injectors they run stock. I plan on adding larger injectors, new fuel pressure regulator, larger fuel rail, and steal braided fuel lines. This is all to support my larger turbo that is supposed to flow up to 700hp. I have heard of adding aditional injectors but I would rather do this.

you will have to ditch CIS and convert to EFI to get that kind of power. Its pretty much impossible to get over 500 fwhp with CIS.

Dear Danny,
You are obviously not familiar with the CIS (continous injection system). The kind of modifications you are talking about will simply not work. The whole system works on calibrated fuel pressures. Mess with them and you screw everything up.
You need to speak to an expert in this area. ImagineAuto would be first on my list because I know them.
700 HP out of a standard M30/69 engine is a real pipe dream. I also recommend you check around and see what companies like RUF reliably managed to obtain out of these engines. Look at what they got out of the Twin Turbos with Motronic and you are aiming for 150 HP more than a RUF RTurbo. I am sorry to be a tad harsh with my comments but you cannot turn a 320 HP engine into a 700 HP engine doing the modifications you suggest. What you may end up doing is turning a 320 HP into a 300 HP engine.
Ciao,

www.autostream.com my friend has a c2 turbo and had 600hp even b4 his fuel system swap and engine over haul. I own a supra with 800 hp and im just not familier with how the porsches fuel system is set up. With out switching the fuel system what is the max HP you guys have gotten out of ur car. With basic mods like headers and a bigger turbo what should I expect.

Because of CIS limitations, 500 mark safely will be it. There are ways to push it, although it is not if, but when it pops. An EFI conversion would be necessary for more HP.

now is that 500 hp at the wheel or crank?

Adrian, I think you are "obviously" trying to be harsh....as diplomatic as ever! Quit trying to scare the new people away!!

Danny, lots of good info on www.turbo911.com if you've got some spare time. If you want a diagram of the fuel/turbo system let me know, I can fax you a copy.
