Feeler S.D.W Debut...M30 to M20 T/B Adapter

[e30 sdw]

Updated with installed pics. 90% finished. I am going to be driving for testing. Have to figure out hardware, and work on a intruction sheet.

Sand casting may also be a cheaper alternative to CNC time

I have already invested too much time and A fair amount of $ to have this machined. I already have an idea of what it would cost me per piece. I just have to put the additional parts together that you will need...hardware etc.

Updates

updates?

My appoligies you guys. My Dad went away on vacation so I have been busy with the shop & Wife and kids on the weekends. This Friday I assure you I will have pics up and I will be mounting it with the stock airbox. I will say I did a quick bolt on and test drive and I did notice a difference. But more information and detailed pics on Friday.

I am interested as well. I have been wanting to go a little larger on my 2.9L 10:1 m20

updates?

Well im interested. Dont count on me, but it would make a good addition to a build i may start soon

This piece is designed for people who have done some serious engine modifications. Forced induction engines will benefit due to the increase in air allowed into the manifold. Stroker engines will too allow more air to come into the manifold. Upon improving throttle response, noticeable gains will be felt. There are alot of options out there to increase fuel via FPR& injectors, the way we can add more spark capacity to the plugs but sometimes limited to our air control options. This piece will give us more options to fine tune our engines. Thanks for your feedback.

Agreed. This is not a power mod for stock m20s by any means. Strokers, and boosted cars will definitely benefit from this mod.

That's a nice looking piece, but I doubt it will show much of a gain. Larger TBs may improve throttle response in many situations, but they usually don't prove much on a dyno.

For boosted applications this would be more beneficial. Only a high strung NA motor with a large cam(s) benefits from an oversized TB.

Good luck either way, and I'm curious to see the results.

This sounds fairly cool. I'd be down to pick one up for the eventual m20b25 I'll more than likely own JUST to have it around.

Keep us posted...

I will, by tomorrow I will have pictures of the factory airbox installed.

I am interested. Would this allow the use of the stock intake elbow + afm + air box? Or will the extra plate push everything out all weird?

I will be testing the part tomorrow with the stock parts and without. I am currently running an M30 AFM but will bolt on both products. I will give you more info this weekend. But yes I am designing this so we can use the factory intake boot. A new boot will go around both the m30 AFM and throttle body.

Good Question BTW, keepem coming you guys. Thanks
