The official turbo build thread.

I rewired the VR sensor the way it should be (maybe ) and playing with the VR sensor pots, i dont get that starter kick back!!!! WOOT

I get ignition for about 1 revolution. If i catch it right with the throttle open kinda itll run for about 3 seconds really weak.

Its a start!

Not really. My tuning computer is so stuck in the stone age i have no good way of getting the msq on it haha. I got a new computer in the mail :)

I think i got the settings mostly all set and its more my hardware set up. I learned how to start from scratch with the fuel deal. I have a known timing table and fuel table. Changing everything, i cant get any better or worse results. This leads me to beleive i have the VR sensor or something else messed up.

Im getting some starter kick back which means im igniting early. I cant get it to go away with any settings to the program with in reason.

I also cant seem to get my CLT, MAT sensors reading anything useful. My father thinks that its the temp thats making it ignite early but i have temp related ignition turned off.

We'll see ...

Where you able to do anything with the MSQ?

[So Live]

Yup :)

Go copying someone elses adapter write up!!!!!

[aaron.j]

sounds like you have it wired incorrectly.

Turns out my TPS is reading 254ADC both at wot and closed. HMMMM somethings fcuked up there. But! setting the flood control value to 255ADC (the highest it goes) it will start!!! So far ive got it to fire 1 revolution. Im gonna try n get it idiling today. With no wideband i cant go very far. Ill have to troubleshoot my tps situation a little later.

Im so excited!

So MS is busting my balls haha theres a surprise. Its funny that i can get a board that was developed for fuel to have spark but no fuel... :)

Im getting a new msq from a running nonvanos motor (THANKS JON!!!!!) so i can rule out the set ups.

Still waiting on my o2 sensor :( i relaly just want to say my car will start on MS. Should be a good weekend.

Thanks!

So my ST front sway bar turned out to be a oem bmw cabrio bar! The "hardware" i confirmed it would be shipped with was the stock rubber bushings and bushing holder things and nothing else. MOTHER FUCKER!!!!!!! Thats the most expensive used e30 cabrio bar ever!

Finished with my small housing project!!!

I modded the housing pretty heavily. Plugged up all the holes to clean up the flow paths.

Not nearly perfect but much better than a 3/4 inch hole.


The reason i started this mess :)


Theres a reducer inbetween there too which is why i went with a female-female 90* fitting.

Schweeeeet


21cm vs 12cm


Cars so much more fun. Full boost by about 3200 rpm vs 4500 rpm before. Car feels so much more snotty its awesome. Im leaking boost by the waste gate though but i have new gaskets coming tuesday hopefully.

MS here i come!

Jaw:
Assembly is very straight forward. No instructions really but all values are printed on the board.


Found a fried lead on my cluster board and a external wire connecting the two points!!!!


I hate service indicator lights so those got removed :)




The almost finished product


The little cover got damaged on install haha. Its just a real light coat of flat black on some lexan. Well see if you can see through the spray paint... I want to get some "window tint paint" for RC cars and make a little translucent cover.

Also bought some new oil fittings cause summit racing -4 AN 90degree hose ends suck. One was leaking at the swivel!

Bought some aeromotive straight ends and found a trick little stainless female/female 90degree fitting. Threw a restrictor in the line too.

That oil fitting change turned into a 2 day project of lets put on my smaller turbine housing haha. Pics of that will come today.

[So Live]

Bought a JAW (Just another wideband) kit. Im buying a few more v-band clamp kits and getting a 3.15LSD this weekend. Hopefully gettin my new 12cm^2 turbine housing on soon. MS is basically done I have to pull the trigger and make the decision to run the idle control valve right now or not. Once i get my JAW hooked up and good to go im going to be working on MS full steam ahead.

I love working full time ad having the money for shit. Now i just have no time to wrench...

Our little shop here is coming together nicely. My father just picked up a 6.5hp 80 gallon 175 psi Devilbiss compressor that basically kills people. I should have the funds together for my Tig welder soon :)
