I'm going to put on a t04 and run 6-7 lbs. I'm putting a custom kit on and don't know what fuel upgrades I should do. I know that s2ks' have 360cc fuel injectors and was thinking of ugrading them and also adding a bigger fuel pump. Or should I do something else like just adding an FMU and a pump. I want to put on as less parts as possible due to budget but maintain reliability w/ around 300whp.
Also, what drivetrain upgrades are requered for that much horsepower.
I figure more guys will know what I'm talking about here instead of the FI section. Thanks.

 

drag tec blew up thier tranny running at SIR in seattle. if u havent heard they have 2 turbo'd s2g's. the stock clutch lasted quite a while suprisingly

Were they running about 300whp?

 

May I suggest http://www.s2ki.com. The tech forum on there will have a ton of info on this. Sorry I can't answer your question myself.

 

Without some serious fuel management, you will not get to 300rwhp using 6-7lbs of boost on a F20C. PERIOD. None of the off the shelf kits will make that kind of power, even with the management hacks they supply the kits with. Turbos simply generate too much heat and an intercooler will loose you some efficiency. You must go with a stand alone ECU to make that kind of power.If you are planning to upgrade the injectors you will REQUIRE a stand alone ECU. There really isn't another way to do it right. You can debate it all day long, but you'll need to shell out the $1800-3000 for the management side if you are going turbo.

A more realistic (and remotely reliable) goal would be 270whp using 7lbs on premium pump gas and an upgraded fuel system and a target 12.5a/f ratio.
There isn't any quick a quick and dirty way around the fuel management requirement. The stock ignition maps are way to agressive for a turbo application. None of the commonly available tweaks will address your headaches.

If you want 300rwhp on a budget then you should buy a centrifical supercharger kit from either Comptech or Vortech. These units are very efficient out of the box and a much more stable/reliable platform for FI. If you are concerned about reliablity, a supercharger is a much better way to go. MUCH better. Usually these systems are plug and play. More importantly, they are basically maintainence free!

You should really hop over to the 'under the hood' forum on http://www.s2ki.com. Lots of information is available there and this subject has been so beaten to death that if you post a thread you get flamed to search any of the 300+ (probably a lot more than that) threads existing on the subject.

 

check out ultimate-racing.com we installed one of thier turbo kits and I have never seen a nicer kit for a honda.

 

Thanks a lot guys, you've all been a big help.
