How do you run 15 psi or 1 bar safely?
What is needed to run that much boost safely (other than a tuned ECU)? I'm looking for answers like what kind of fuel system? how much octane? ignition? anything else?

You will need an upgraded ECU for tuning, larger secondary injectors 1200 or 1300 and I would recommend an SX regulator. You can upgrade the ignition - Twinpower - is your best bet but its not required.
Tuning it the most critical item.

all you need is a fuel pump and colder spark plugs. you have to use race gas also.
if you are close to Austin,Tx i recomend MZM performance. they did all my mods.

when my car got tuned, they backed up on the timing and also made the car pretty rich. I boost 1kg, which is a little lower than 1 bar but it's running fine. I have a fuel pump, power fc, and 1300 secondaries.

i run 1 bar with a rotary performance ecu.......just make sure u have an a/f meter to make sure you don't lean out......i also run a jacobs ignition, ngk 10.5's all around, street port, dp, mp, cb, m2 i/c, plus alot of **** i can't think of right now....according to chris @ rp i have not yet surpassed the levels of stock fuel pump and injectors, my car runs hella rich all the time....the fuel system is my winter project though....

To tell you the truth, you can't run the stock twins at 15psi safely for long. after 94k miles (the first 70k at 10 psi and the next 24k at 12-14 psi) my stockers are toast. Leaking oil into the exhaust so that I was intermittently smoking at idle. leaking so much into the intake tract that when I pulled my motor the other weekend, I turned my throttle body/uim on it's side and I swear a quart of oil poured out. And I was warming her up and cooling her down religiously, used Mobil1 15w50 synth for the whole time I ran higher than stock boost.
If you must do it (like I did
) then I'd say supra tt oem fuel pump, 1300cc inj's, upgraded IC, 10.5 race plugs and/or ignition amp, engine management, boost controller.
and if you're going to get an a/f meter, make sure it's one of the super expensive 4 wire 02 sensor deals. I have a greddy a/f meter and it is next to useless. My AFR pro is great, on the other hand. An EGT gauge would serve you much better.
hope this helps

Also about running 15psi and my last post....dont get me wrong i really only plan to run 15 psi on the strip or for the occasional hwy encounter or whatever. 12psi is more then enough for normal whipping around and is actually even pretty dangerous on the road..the car is fast with 12 psi is the point. Also, my intentions are to only run 10 psi on lime rock as it is pretty tough to get good traction with over 300 rwhp with regular tires in an FD.

Also, I agree with you on the boost issue. I was pushing 14psi pretty consistently on the street and I have a well-known heavy foot, so keep that in mind. I don't think the benefits of running 15psi vs 12psi on the street for extended periods outweigh the costs. Now, that's on the lil' stockers. The BNR Stage 2 Dynamic Seals, on the other hand

doesnt dave sell and stock the walhbro pump though? my intentions were just to take it there and have him do the fuel system. Now he is saying not to use it? Another question, doesnt he stock the bored out 1300 cc injectors too. I spoke to him a while ago and he said he has everything i need to get me to 15 psi..the pump, injectors, and the dyno to tune me up.

oh yeah...one more thing goodfella..i think i have been through this with you....but i just checked out your site and love what you did with the AST. Did dave do that for you? What EXACTLY did you use to bolt it up right there??
