Buildup: My quest for NA 280 hp

[Boyracer]

Well well well, it seems that I got the engine running with mega :eek:

Friend is handling the throttle

Engine started pretty easily in the end, after I fixed some problems liek crossed fuel lines and ICV that fed 6 volts to ingition wire preventing car electricts to shut off and causing mega to reset after few seconds of cranking.

Engine runs now but no tuning has been done yet. Must source shorter alternator belt and suitable connector for that Nippon Denso alternator.

Alternator setup:



EGT sensors:



Front brakes are finally getting ready to install too...

[enildeR]

what brakes are you putting on? the rx7 ones?

Did you made a bracket to mount the alternator on the airco mountings? (or did you drilled a hole in the engine )

[Boyracer]

Some progress:

Small Nippon Denso alternator from Toyota Yaris charges the battery as it should. Vacuum rail is finished. Alu header tank has been installed etc. Basically car now moves again on it's own power, too bad it has not passed road inspection lately :p

I need to make some basic tuning on the road before going to dyno to tune igntion map. Also I need to find out if the car holds together in general, lots of changes...

Engine load is now MAP based but that should ideally be switched to ITB load mode before dyno but I don't have enough data to use it yet. I hope to install Shrick copy camshafts soon too.

Car is back on it's feet but not yet running, need bit of vacuum hose, modification to DIY vacuum rail and then I can test if engine starts with megasquirt.

Hello, I'm also installing a throttle body in a m3 engine M42. How did you adapt the throttle body? There are adapters or something you've created. I'm installing a control unit Megasquirt PNP. Which performance did you get? Forgive me if my English is not correct, I'm Italian!

Hi there!

I watch this project with great interest, i think its one of the best projects of the M42 around here! Congratulations.

I few pages back there was a search for bigger intake valves that could fit the M42 engine.

According to supertech valves:

BMW M42 intake Valves:

Head Diam    Stem Diam    Length

33mm                5,97mm          106.10mm

And i have found the Peugeot  EW10J4S intake valves to be the exact same dimensions but off course larger in diameter:


Head Diam    Stem Diam    Length

35mm                5,97mm          106.10mm

Is it possible to make it work?

Congrats on the build and keep on going!

[romkasponka]

It should work. Also it depends from Valve collet where it is.

what happend to this build?

i used to check up on this one (and his previous one) regularly. amazing builds!

[Nicolai-Denmark]

So did he make his 280hk mark or what?

[Boyracer]

Not yet

Finally 1.5 years ago I bought a house with space for workshop and garage so I could work on the car.







I also bought another identical 318is Class II:



Original project is being stripped bare to be ready for roll cage, pedal box and completely new electrics:



On top of that, I got an offer to work on norway which I accepted... Now I have money and room to build car but no time apart from vacations 

[keflaman]

Welcome back!

What exactly is a class II?

[E36-italia]

What exactly is a class II?

homologation specials.. quite a rare car i believe...

[Tgoode318]

I like your "werkstatt" sign it adds a nice touch to the garage

[Darky]

Excellent
Glad to see this continue!
