Febi Guibo's Excellent Adventure...

[silverblades181]

im interested in more details

febi's spot on, there are high and low impedance injectors and our standard injectors are high impedance, and the motonic will require high impedance injectors if you swap as low impedance ones I expect would require some form of current limiting - resistors, pwm etc.
you can find high impedance 4 pintle injectors, I have 23.7lb 4 pintle high impedance injectors in my 2.1.

Personally I still believe on a standard 1.8 you will not need larger injectors, and that the stockers are the best injector for the job. If anyone wants to post up aftermarket injector p/nos I can check their impedance, flow rate etc.

I don't think that's true. I calculated max hp the stock injectors could support and I think it was a bit over 140. If they're dirty, not even that much.

So, what is the deal with the resonance chamber intake manifold?  From the pics it looks like the stock upper manifold was chopped & had these custom endcaps welded on?  Any info on this thing would be great...looks like a hell of a deal.

The injector thing: the impedance part is correct.  Our stockers are 20.5# @ 3BAR correct?  I was one of those that mistakenly put in some S50 injectors (4 pintle).  Supposedly they are 17.5# ones.  Being that the car is not running super lean, that must be at 2.5BAR.  At 3BAR they should be right about the same as the M42 stockers.  Can anyone confirm?

Anyway sweet project Febi.  I am most jealous.

How did you calculate that? I have the bosch p/nos and flow rates and have done all me sums! They are more than adequate for an M42 by most conventional calculations. Not only did they provide 13:1 AFRs all the way through at WOT on my 1.8 (verified on the rollers and by my LC1 wideband), in fact they were providing 13:1 AFRs on my 2.1 with ITBs without giving up, although the PW was getting pretty long.

bmwman, give me the part nos. for those injectors you have - obv we only get the euro S50 over here so i couldn't tell you their flowrate.

HAve anyone actually dynoed these strokers?

It has been G-tech'ed, but that is all I think, but I can assure you it is about what they claim.

[Frankie]

It would be great if someone who has actually done the whole process succesfully would create a list of part needed in order to create a m42 stroker. Also info about prices of the parts and where to get them would be great.

At this stage the it is very difficult to obtain that information. Of course not many projects are finished, but it surely would help others in order to start own stroker project.

Then sticky it.

Why not just buy the motor from MM?  I know it's more than DIY but then you can be pretty sure it runs correctly.  It's not a matter of just getting a bunch of parts from anywhere, MM machines certain parts to improve oil flow also.  And you need the software I developed for that motor also, you can't use any other chip.

Do MM ship to Finland`? What about guarantee?

And the Ecu can be done by a specialist.

You would have to talk to them about the warranty and shipping.

I do know they will back up their work, and A LOT of planning and work went into this motor. It is not something you can do on your own. Sure you could stroke and bore it, guess on a  good cam, but you will not get that high of rpm reliably, or the faster response that engine has, or the strength, or...

I would honestly say their engine is better than factory. Everything that can be done to ensure a long life has been done. They even fixed some problems that were built into the engine. I doubt they would have let Febi take it fresh and drive half-way across the country right away if they did not believe in it.

I saw how it was made, saw how it performed, and saw how much thought was put into it, it is a work of art. Worth every penny, I just wish I could afford it. I have also seen and dealt with a few people who have the 325/328 strokers they have, they are monsters.

Very few engine builders could pull this engine off like they have. There is no way a backyard mechanic could do it. Maybe if you had the time, a huge supply of M42's, tens of thousands of dollars, and a whole machine shop, just maybe you could do it. Maybe...

The rods are custom, just for them.
The pistons are custom, just for them.
The bearings are custom, just for them.
Many surfaces are coated.
Parts are shortened, lightened, reshaped, drilled for oil passages, unshrouded, ground smooth...

I think EVERY part in the engine, has been modified or custom made.

well i really do think he can hit 13's with 210hp at the crank. he just needs some slicks or drag radials and a killer launch. if a 260hp mustang GT with 4.56 gears, slicks and exhaust can go 12.8-12.9 (a few guys back in the early 2000's from mustangworld.com were) then a 210hp 2400lb E30 should be able to do high 13's. if you check with a simple E/T calculator the physics work out.
