M44 upgrades

[MoMansi]

getting there

[MoMansi]

ready to be finished and some polish i guess

[MoMansi]

the lower part of the manifold and the middle plate and the gasket, the three are way off each other!
i will address them soon, maybe in a couple of days.

the upper manifold porting and enlarging for the air box, should be very useful for high rpm, the runner will be 33% shorter and the air box will hold more air, we'll see.
i got the idea from a friend tuning his VW Golf with VR6 engine, they do the same thing, the results are significant, like the M50 manifold on M52 engines, that kind of results.

any ideas?

[MoMansi]

that area

Hi

No ideas sorry most people go for e30 m42 intake or itbs, not sure what your going to get! But very interesting.

Cheers Rohan

[MoMansi]

well, Thank you Rohan,

i'm basically trying to keep the low rpm torque characteristics and drivability of the car while improving the top end breathing as much as i can.

best of both worlds 

Cheers

So your going to open up the secondary inlet system (high rpm) of the disa.
How much do your think you will get ?

Cheers

[MoMansi]

honestly, i don't have any figures in mind, i'm trying to squeeze every possible gain at this stage before moving to hotter cams and head work next year, so for now, i got lightened flywheel, ported manifold and will check for a good machine shop to try the secondary butterfly of the throttle to be bored out to 57mm.

cheers

You can run 10.000RPM with hydraulic lifters.. but not the stock ones... any good (and therefor hyper expensive) engine builder can make it work for your car.
F1's pneumatic valve systems are an extreme example of it.. just one step further.

'mechanical' lifters are just cheaper, but less efficient..
sure the ducati desmodronic engines have lot of power.. but the amount of friction the desmodronic has is insane.

btw, where are you located to have 2 (!!) S14B20 engines?
there are some E30 320is cars on sale in italy now.. but they are overpriced if you ask me.

Is it possible to get uprated lifters and followers for the m44 off the shelf or off another engine?

[MoMansi]

i'm located in Egypt, i owned a 320is before, and still in love with it, had two engines in my garage, and there's one for sale in cairo also.

would love to have this car again if you ask me, yeah they are over priced, i may look for a scrapped one with the engine and drivetrain intact later.

Cheers

[MoMansi]

by the way, what are their prices now?

[E36-italia]

by the way, what are their prices now?

cheapest is 16.000 euros.. and the most expensive is 23.000 euros.

For that kind of money you can buy a nice E46 M3 / E60 M5!

[MoMansi]

Damn!
very expensive!

[MoMansi]

i got my first one back in 2005 for 1000 euros
