here's the deal, i have 400 extra bucks to spend on parts. what do you think i should buy?

list of mods: power fc
full exhaust
petit intake

in the mail:
supra tt fuel pump
like new 550 and 1300 injectors

possible ideas:
finish smic setup
wideband
datalogit
body components(nice but i would rather be going faster, and have
a better idea of how to fine tune my machine)

any other thoughts?

 

A 99spec lip, Boost/oil presure/w. temp gauge, new springs or shocks (shocks will be a little outta the price range though) . . . . this is what i'd do

 

Pillowball bushings and dust caps($370)!!! You won't go any faster, but if yours are worn, the ride will be alot better.

 

Innovate wideband or any for that matter. Just got mine hooked up and it has been a great way to see whats going on in the motor for diagnostics of many things. Cured my idle problems on ported motor so it purrs like a kitten now. Next will be road tuning to cure my miss running above 13 lbs. of boost. I found out my air/fuel ratio is pig rich in this range and I believe i can lean and cure this problem with this tool. My next favorite is an electronic boost controller. Good luck

 

Pulleys
and the 'complete' steering rack mod to remove power steering.

Get rid of PS, Airpump, AC.

You should have a bit left over for a sealed battery and the battery relocation to passenger bin.

 

Tuning! But its your money and your going to spend it like you see fit. I would also suggest bushings since they are more than likely shot.

 

Assuming you are paying for maintenance items separately, I would get the wideband. Apply the leftover to getting a better intercooler, which you are going to need pronto.

 

i have a core for a smic(12x18x3), im working on having endtanks made along with piping. i already have a duct for it too
i have springs, and my bushings arent very clunky
i just bought a westco miata battery to put in the driver bin, buying welders 2 gauge wire soon and looking at posts to route it through the cabin and under the bins. planning on making a battery tray that fits in the bin, holds the battery snug and bolts to the floor(watching out for fuel lines). 200 amp will be bought as well

as of now im leaning towards a datalogit or a wideband. wideband will definitely be bought soon if i get the datalogit.
i'm weighing which is more worth it: monitoring afrs w/ a wideband or monitoring and tinkering with a datalogit.
anyone know if datalogits are on back order?
also with wideband, which has the easiest install and greatest range of fucntionality? im not really into splicing into wires, as i cant really do this myself.
and are there only specific ones that can interface with the datalogit?
i guess which one would you recommend

and as for tuning im planning on having steve kan do it when he comes to st. louis in june

 

Innovate with guage was approx. 3 hours including welding bung in the midpipe.

 

I agree a wideband will be very helpful.

 

do you have the wideband constantly plugged in? if so how long to the sensors last? ive read that some people put in the wideband only when logging afrs and use the narrowband otherwise.
so would i take out the narrowband in my highflow cat and leave the wideband in there permanently?

 

I have the techedge wideband and I love it.

 

personally i would finish the intercooler. The wideband is less necessary if you are already tuned by a good tuner. You may want to get the car retuned for more power and/or reliability after the intercooler is done...

 

Someone with a power FC will have to answer that. Microtech, which my car runs on, does not use AFR for controlling fuel functions, only monitoring.

 

As long as you aren't running leaded race gas you don't have to worry. The wideband o2 sensors will hold up well to pump gas, and with the techedge I was able to order a compatible vw sensor that is only like $40 to replace.

I believe their website is www.wb02.com although it is a bit confusing to order from. If you search under my username and 'techedge pics' you can find out the specifics of what I ordered.

It depends on usage - when mapping other peoples cars, so constantly moving the sensor and having stupid AFRs we go through sensors at a fair old rate. Equally the one that's wired into my car has been there for almost 2 years and still working fine (will see how long that lasts when it's moved to the narrowband bung in my new downpipe, currently located near the bottom of my HKS dp).

Have had O2 feedback switched off on my PFC for the last couple of years. My map is leaned out as far as possible on cruise, so switching it on wont help mpg.

 

im looking your threads now, but there are 10 pgs worth. any idea when you posted your setup

looks like you went with this one

http://wbo2.com/2a0/default.htm
WBo2 2A0/2A1 Complete System with LD02 Display
There is a choice of cable lengths (2.6 & 4.0 m), and sensors (6066, 7057 & NTK)

but im not sure of cable lenth or sensor choice. care too enlighten me.
and where is the option for that sensor?

thanks for all the help guys

 

Pretty sure I went with the shorter cable, and I think this is the sensor I went with:

For 2005 we have a limited number of NTK-VW sensors. These are L2H2 sensors but branded as Audi VW parts.

 

are the NTK-VW sensors better than the bosch?
and is this wideband plug n play or does it splice in some wires somewhere?
sorry, i know i could possibly read this off their site, but its a lot of stuff there and semi-confusing to find your way around.

 

anyone have any experience with the plx m-300? plug and play interestes me and i dont need datalogging b/c i will be gettign a datalogit soon and the plx can interface i with it. also id be saving 150 dollars over the techedge

 

Chuck Westbrook uses it...and he's probably done more AFR datalogging than anyone on the board. It's a good unit. I would go with the M-250 to save even more money. You can then use the PLX gauge with it or just view the result using Datalogit.

 

i think thats what im gonna go with.

thanks for helping me spend my money

 

Finish intercooler, relocate battery, and hks twin power if you can afford it!

 

I agree on wideband.

 

I have the AEM UEGO wb and i love it! took me an hour and a half to install including welding the bung in my new hi flo cat. it was a sinch. i run my wideband all the time, im not taking a chance on blowing anything because an o2 sensor is too expensive. if that was the case, i bought the wrong car. just my opinion of course...
