will have to pull the plenum again as I have a small coolant leak near the firewall.
more detail on the rough engine running, there is a CEL, idle is high probably 1200 rpm. when you apply the throttle I get occasional backfiring noise but no engine speed increase. sometimes with the throttle opened revs go up for a second but then they drop right back to idle despite the throttle position, as if there was no fuel or something.
Pulled out my Peake tool and got a fault code 35 = full load switch. I've got a note in to sssquid about whether I can keep the stock 3 wire TPS or not. I'll also try putting the stock chip back in and see if the engine behaves differently.
some info here

HAHAHAHA
TPS and ICV connectors are the same. Swapped them and boom - problem gone. Induction sound is just terrific!
remaining work to first drive
- Idle's at 2k. make sure there's no linkage issue
- fix the coolant link
- attach the cable to the throttle pedal
- get a cone filter or figure out how to get the airbox inI BUY/SELL REFURBISHED CM5907s & CM5908s

welcome Lietuvis! glad to see another live dbilas project as well.
My dbilas was originally on this Hartge tribute car in Canada. It's been painted and is probably early production.
I have alot of info about dbilas and M20 ITBs starting about here. There are many links to good information. digger in australia is an expert on ITBs. His 3.1 stroker build thread has amazing information.
thanks for posting pics as well! dbilas really cleaned up the throttle linkage! mine looks much less refined, more like a prototype.
I should have my car driving by this weekend and will find out how bad the midrange torque drop is. The biggest problems are the plenum design and ITBs being too big. So to really make them perform NA (normally aspirated, no turbo or supercharger) you have to stroke your motor and replace the plenum. There was a german company that built a carbon fiber plenum for M20 but I cannot find any info about them anymore.
Racehead in Australia seems to have the best M20 ITB setup out there now. It has long runners, and they just now released an airbox for it. There are no pictures of it installed yet, but this guy in the US is installing the new airbox on his setup soon.Last edited by bradnic; 09-03-2017, 02:06 PM.I BUY/SELL REFURBISHED CM5907s & CM5908s

You must scour the Internet for some of those pics Brad!!
Your bookmarks must be all ITB/e30 related.
I may try to hook up with you over the weekend. I have your number via PM. I also have some questions relating to the Vintage in North Carolina this year. I thought I read somewhere you are attending?
I scored today off so the wife's e90 is getting a complete interior/exterior detail!!
XRT on in the garage and the weather is perfect!

Cheers dude!
I was thinking about RHD ITB when I heard about it, but IMHO for my daily use in summer, with "open pipes" is not very good for engine dust/sand from the street. Yes, I know at this moment he produces carbon airbox.
So I decided to buy Dbilas ITB, because where is no custom taxes in Europe, if you buy from another Europe country, from Australia it would be RHD ITB price + approx. 400 euros taxes.
Where is one company from Germany, they are making Carbon AirBoxes, take a look

running great, no leaks, idle still a little high
all that's left is connecting the throttle cable to the pedal linkage.
- went through 2 different coolant line cap setups before giving up and putting the throttle body heater hoses back in. maddening pulling the plenum and rear ITB twice to get to the fittings. Also had a loose fitting on the bottom of the throttle housing
- I did not have to cut the housing for the water temp sensor connector. just added an extra washer to it, allowing the sensor to clear the fuel rail better
- cut the intake boot back on both ends and that cleared things enough to get the airbox in the stock location! thrilled about this :-) had to bend the bracket a bit but that's it.
idling at 1500 right now after adjusting the throttle linkage mounting position. will try the 2 idle screws next.Last edited by bradnic; 09-03-2017, 02:12 PM.I BUY/SELL REFURBISHED CM5907s & CM5908s

lol. she's all done except for throttle adjustments. my exhaust sounds different now - lots and lots of gurgle off throttle. intake sounds comes alive at 5k. butt dyno doesn't show much going on different but we'll see.
bit of a rise on the hood. probably the AFM

hundreds of them, all e30 topics, especially anything euro related.
I'll be in my garage all weekend so please do hop on over! weather's gonna be perfect.
