alright... I get paid min wage and only get about 25 hours a week so i need to budget. I currently have Hahn's stage 2 with fmic and thermal catback (more info at www.cardomain.com/id/carbonfiberrst) the engine is built with 8.8:1 and I want to run more than 8psi.

I have seen a few people running high levels of boost off their cartech fmu and I would like ALL the info I can get on how you went about doing this and how well it works... thinking of 400-500cc injectors and a manual ballvalve boost controller... will this work?(daily drivable?)

over time i can get a piggy back or electronic boost controller but I want as much as I can get out of what I have now. I spent over an hour reading after searching and I didn't find all the info I need. just that it has been done and a few details.

chill factory's unit http://www.chillfactory.us/regulator.html is an option i could go with but only if necesary b/c its more $$$ and I can get 93 octane were I live. I want to run atleast 15psi.

Also would a wide band o2 sensor be necessary? currenty i have a CEL for the stock o2 sensor... and i repalced it and after 160 miles it came back on...

help me out please and if what i have listed isn't enough to accomplish 15psi sudgest the minimum items necessary and any tuning tips anyone has are needed...
TIA

just go buy one of those $20 manual boost controller's off ebay and hook it up. If you have forged internals then 15 psi shouldn't be a problem. Just try not to lean it out. Get the sfmu with a 12:1 disk and start tunin.

sfmu? that isn't what came in the hahn kit is it? if not can i modify the one that came in the kit to work? injector size sugestions? hopes for 300+ whp down the road after i get a better job... 500cc?

slap some 440's on there :P This is for the turbo section btw

poop, i wasn't sure... :-/ my bizzy

so 440's are the way to go then?

so i need 440's and the cheapo boost controller... all i need to know now is what is it about this 12:1 plate and will it work with my fmu dealy

ok i have to buy the SFMU and 440s. hahn's stage 3 that is designed for 15psi comes with an ignition to perform retard functions... i am hoping this isn't necessary? and will is the a/f ratio reading that the apexi turbo timer reads accurate enough for basic tuning? the 12:1 is recomended for 440s or was that suggested for stock injectors?

Be careful, some of the info above is not accurate. I do not have time to reply in depth. Do some searches in the turbo section. Try SFMU or FMU. It will tell you what people have been using for fuel and what size disc to use with what injectors.

This can be locked as it is not an advance tuning topic.
