I'm looking for an ITB kit, for now Dbilas looks to be the only option in Europe, also  I'm trying to find an MAF conversion kit does anybody knows if there is such kit for M42?

So  this would be https://dbilas-shop.com/en/intake-tract/throttle-body-kit/street-version/bmw/m42/149/throttle-body-kit-for-bmw-e30-1-8-16v-100kw-m42b18?number=10.010.005&c=11152 does it make sense to go for a higher diameter 48mm or 50mm? Car is stock just a ebay chip and i think the head is from a M42 E36 should have 6mm valve stems .
RHD kit is nice but after taxes and shipping i think it would be double vs Dbilas.

Hey Alex,

This is a tough choice. It all depends on where you are going with the engine and it's development.

The dBilas unit is 45mm and they now have other options. The RHD drive option is 44mm.

I've had the dBilas and I would probably opt for the RHD if I were to do it again for the street.

For the track....I still have my slide throttle assembly sitting in a box. 

No matter what size you choose, you still need to have the engine tuned. My suggestion is to get rid of the AFM and go MAP with Alpha N.

Lots to think about my friend. I hope I didn't confuse you.

Cheers,

Hello, Warsteiner the ideea is to keep the engine stock(i mean after i bought the car engine was opened and we changed just he main crankshaft bearings everything was ok so we did not modify anything i was planning to do a stroker but parts were not available ) Now the plan is to raise the power using "bolt  on " options as much as possible so plan is :
- ITB
-some aftermarket ECU  i found this? https://lowcostracingsolutions.co.uk/pnp-standalone-ecu-s/56-119-bmw-e30-e36-e46-m50-m52-m54-m43-m42-plug-and-play-standalone-ecu.html#/39-accessories-just_ecu and Alpha N

My greatest fear is that i will not find some one that could program the ECU , i mean know "tuners" but this guys worked mainly on M20/M50 S52/S54 since the common practice was to throw the M42 at garbage and they are not very keen on working on this motors , usually they are saying get a 2.5 M50 and you will have the same power as an " tuned M42"
So to recap : bolt on's , internals = stock i  camshaft will be stock if possible first step - ITB's then if all goes well  Alpha N and ECU edit : well looks like Dbilas have also Alpha N https://dbilas-shop.com/en/electronic-system/engine-management/alpha-n-control-unit/bmw/2649/electronic-alpha/n-control-units-bmw-1-8-16v-m42b18-1.9-16v-m44b19?c=13217

Alex,

The biggest bang for the buck without doing a rebuild will be getting rid of the AFM and going MAP with Alpha N. Get your ITB's of choice. If you can do the cams now, then do them now and then get your tune with whichever standalone you choose. Talk to your local tuner and see what they like to use. The only other thing that will wake up the motor, but not add any HP but make it feel much better will be a lightened flywheel. Get one around 11-12lbs and made of steel if you can. You can take M20 FW's and swap the ring gear from your M42 or you can change the starter to an M20 with the M20 FW.

Those are my suggestions for you.

Good Luck!

Cheers,

Got one of this https://www.supersprint.com/ww-en/bmw-3-series-e30/supersprint-performance-sport-exhaust-bmw-e30-318is/centre-pipe--rear-exhaust-90x70-steel-409.aspx#!/  was on some discount paid 540 eur   . Still waiting to see some discounts on ITB's  . Also my FW is pretty light since i don't have the AC version.
