B3T aspire

[bhearts]

I'm going to do this the rightish way. I'm preparing my car with the proper gauges and giving it a good freshen up of parts before I'll let myself proceed. I'm looking for a narrower radiator, maybe a 2 row, so that I'll have enough room for intercooler piping and turbo wrenching. I'm using a 9b turbo and I plan on keeping my stock aspire air box for now, which I hope to plumb into the fender for fresh air. I built my own O2 clamp and I'll be using a 5-1 fmu with bigger b6 or b8 injectors. I'm going to run my rail pressure lower, whatever it'll take to compensate for the bigger injectors. I'd like to be under 30psi, does anyone have an opinion on running fuel injectors under their rated pressure. I'd hate to lose serious atomization on my fuel, at least at cruise that is. I'm using a stock aspire mani and have a custom cut b9 flange to weld on to it. I plan on installing a water meth kit, that of which I'd like to build my own circuit to pump the flow up with the boost. I've always thought of using a whole separate fuel regulator and fmu, maybe a 12-1 to accomplish this, does anyone have input about an fmu for water meth injection. It could be put together for alot cheaper than the computer controlled bits the companies sell for the water injection kits. Did I miss anything? I need a set of fuel injectors so pm me if you have some you'd like to get rid of.

That project box has tons of room for new circuits. And it's top and bottom are see through and removable. Pretty cool if I must say so myself

With this build, I will record fuel economy numbers and I'd like to give hp numbers also, with every mod that gets done post turbo. Whenever it blows the head gasket, which I assume it will eventually, I'm going to get the head milled 30 to 40 thousandths. High compression turbo!!! Hot exhaust for quick spool.

If thats a cheap narrow band air to fuel ratio gauge trash it and get a quality wide band.
the narrows are nothing more than a fancy light show.

Watching.

That it is technically a voltmeter, it will still alert me if my mixture goes leaner than ideal, I think the difference in money would be better spent on a water injection set-up

Cause although the lights on the narrowband gauge do bounce around alot, they are a direct representation of the current state of the air fuel mixture. Which is useful info for fuel economy and performance, but I do say performance on a beginner's scale.

You absolutely can NOT beat a wideband setup. Especially with a homemade turbo setup. A narrowband will not tell you what you need to know. Narrowband sensors are basically on/off switches.

I remember reading about a wild build where the guy tuned using nothing but an EGT gauge. Have at it.

[Damkid]

I was once told that EGT gauges were the old school way of tuning.... Widebands are just new school and more accurate

[Rocketman]

+4 for wideband...tuning is a breeze with it and you'll instantly know if you're safe. Trying to use narrowband will be more frustrating than useful

Water/meth injection...how much boost are you looking to run? If you're not running an intercooler, you can run a pre-turbo injection that runs off pressure differential, more boost = more flow

Running an intercooler & under 10psi of boost? Don't bother with water/meth

[koRnhead]

Yup, that narrow band is useless. EGT's will work fine. thats how many turbos were tuned for years. You will either want to go that route. or the wideband o2.

[bhearts]

So if I was to come across a wideband. I'd like to use water meth injection so I don't have to pull timing. Does anyone have experience with direct port water meth injection. That's the method I'd like to use

You dont need water/meth at the boost levels you will be running. a wideband with a spot on tune in the car. Will get you more power and reliability than using meth to cover over issues.

[bhearts]

I'd like to eventually run it at infinite boost, which means turning it up until I can't anymore. Obviously will need the clutch addressed and I'd prefer to maintenance the head gasket before I go too far. I don't see why not with water meth, especially at mixtures with more meth than water. The garage I'll be doing my work at has drums of the stuff on tap. It might allow me to even run regular pump gas as a main fuel.
