m42 itb build V2.0

[defaultName]

Have you looked into using Euro S50 ITB's on an M42?

I'm assuming it would be a cost/availability issue to go this route but it could be easier.

Just wondering if you know anything about this set up?

There is a chance i may have to... But ill know for sure when i start putting it together.. But i still want to kerp long runneres to help with my tq curve

Default name... I have heard and seen that on some threads.... They are very costly.... Imo motorcycle itbs are cost effective. The first set of itbs shipped to my door was around $120 i think... These $180... Those euro bmw ones when i was looking well above $400

well it took some time but a friend of mine was able to squeeze in some time for me at his shop to do this...









next up.. to make the two units one again.. fill the holes...

been a little busy with some other things so the next few steps may be a while... but not as long as this update was.

Any plans on adding an adjustable fuel pressure regulator and a WB O2 sensor to help tweak the fueling in the mean time? Eventually you will need to go standalone though...

well... not sure if i need a fpr... i was told it will be fine along with the stock injectors.

Maybe, but I'd still consider installing a WB O2 though so you can see how the DME adjusts and keep an eye on things.

I can give you a hand if you'd like. It's pretty straight forward. I installed one in mine before I started fooling around with the M30 AFM and 19lb injectors. And two years later it's going to come in handy for tuning my 2.8L stroker which will be running stand alone

Little update...

So i made the tab extension to connect the butterfly rods together. I used rivets and it works... But i did notice some play. So i brought the unit into work today to see if the welder can fix it. Ill pOst some pics when i can...

After this im going to work on plugging the holes and setting up for the secondary vac log for the valve cover vent. Later on that will have an oil catch can. After thats done going to work on the fiberglass plenum
