E30 #2: 1990 Delphin: RHD ITB M20

An air box was the only excuse I had for not buying a set before but plans need to wait as I need a real daily driver. With the kit already assembled how long do you think it took you to install and have everything buttoned up?

It's a purchase I've been very happy with.

Outside of the megasquirt stuff, I probably have about 8 hours in EVERYTHING associated with the install: Making the brackets for harness relocation/catch can, swapping the throttle cable, pulling the manifold, getting everything on and synced, etc. I also work a few hours at a time, and at a very slow pace ;).

it's always a bummer to find a great build thread and then reach the end of it... everything looks great. The picture of your car at the gas station made me a little wet.

Hopefully there will be more to come.

Please don't be wet.

SUB'D

heard from Rama that an airbox is finally available for the RHDs. Can't wait to see them installed on your ride. I bought a dbilas setup a while ago and am finally installing it now. Doing things in stages.. down the road I'll either leave the dbilas and FI the motor or possibly switch to an RHD setup.

had the RHD airbox been available I definitely would have gone that route.

I don't know how I've missed this 2 yo build especially for a local car. I'll save my 2 years worth of commentary and just say that I thought I was anal about details but this....lol

Hope to see you around town.

Stages is usually best. Maybe digger has some ideas for squeezing more out of that dbilas setup?

Details are fun! The car will usually be out if the weather is nice. You have quite the find! Lachs is sweet.

I like the cluster - but think it would take some getting use to after so many years of being use to seeing the normal tach position when driving.. Kudos for trying something different!

Ditto. I'm usually in the Cabrio though which is notable for its matching red bbs center caps :)

I'm also at carsncoffee every so often.

funny you ask that.. his writeups are amazing. the consensus seems to be loss of midrange torque compared to stock due to runners being too short and 45mm throttle bodies being too big for a stock motor. he also wrote this:

SUB'D.. still haven't installed my dbilas yet.

please sell it and use something better in that case.

anyway I got them running now and they sound fantastic. I want to stroke and FI anyway so I can probably flatten the torque curve out and get the power I want when I do that. If I started it now though I'd go your route with the new RHD airbox.

Can't wait to see it!

Haha it did. I mostly wanted to clean up the speedo and get rid of the econometer. I like the tach more than the stock one now.

I'll keep an eye out.

I'll post details and my impressions when it gets done. Digger is a phenomenal resource. FI will certainly fix any curve issues you may have had:devil:

Hell yes lol. I'm not looking for kamotors power. just an as wide and flat a torque curve I can get without vanos. also plan to get the boost gauge that replaces the econometer. so I love your tach ALOT but really hope I can get the aftermarket boost gauge in there.

I've always coveted that econometer boost gauge, that guy does good work. Do you know what flavor of FI you're after?

[bradnic]

going with a vortech supercharger after the motor is stroked and headers added. whodwho tried a serpentine m20 setup a while back. that's my target.

check out whodwho's serpentine+SC M20 incredible work. serpentine makes a lot of sense with this application since you'd have the SC, AC, PS and alt all hanging off the crank.




EDIT: found this pic too later in the thread. Man this really looks terrific. He mentioned having to swap out the intake boot (or at least heavily reinforce it so it doesn't balloon or split).



updated setup with boot replaced
