Stock, stroker or ghetto capacity increase? ( supra 7m gte pistons bmw rods )

[prj]

, stock or very soon chipped? i believe to heard sometime that these machines can handle 420Hp only with mapping....without invest anything

Mine does about 450-460 with a chip.
But let's not derail the thread.

can you describe a little this?

3. Get 7M-GTE pistons for almost nothing, machine 1.2mm-1.5mm off the top.
4. Get M50B20TU rods for almost nothing.
5. Get a MC crank, machine to fit rods

i cant understand from wich cars they are ,

MC crank WTF is this?

are you talking about to use stock 220mm blocks? or 236 AAT-AEL blocks?

7M-GTE is from Toyota Supra MK3.
You can also buy them new for very little money:

M50B20TU is BMW E36 320i.
You can get them from the breakers for almost free probably.

MC crank is MC engine code from early Audi 200.
You can also use AAN/3B/AAR etc crank, but as I wrote, more machining then.

And this is for use in a standard stock engine block. Preferrably one where the cylinder walls are damaged and need to be bored out, so you can get it for almost free also.

I posted some info about the car on my website.

now is far easier to understand ,thanks Dmitri¡

so,as far as i am seeing...the BMW E36 320I and very few HP Rods are stronger than our engines?

sounds crazy


Dmitri,and what do you think..could be possible to use the 92.8 stroker cranshaft with this frankestein engine?¿


as you know,i have a 220mm block in Jose Luis Garage..and it is a little damaged in one wall and the main face....it needs machining or go to the waste

[Rusty]

More stroke = shorter rods in the same block, so you'd need to source new rods.

This is a pretty interesting development. A mate ghetto built a 2.1 BMW M42 engine with interesting results...

[prj]

No one has tried building a stroker with this setup, I don't know what rods to use.
I am not an engine builder, just saying what has been done here, and that it works perfectly.

And yes, BMW rods are stronger.

[andy10v]

Thanks for posting the details up on that budget engine build Dmitri.

[Rusty]

Any idea what the big and little end diameter are for the components? Mate's engine had a weak point after needing custom little ends.

[prj]

Small ends fit without machining.
Big ends need crank to be machined to fit.

Don't know the diameters off the top of my head, but I am sure google can help you

[Billman]

If someone is going for new Supra pistons then it is better to buy custom Forged pistons from the start. It costs almost the same.

Cheers, was on my phone and so serious web surfing wasn't ideal.

You can get 6 forged pistons for 120$?
I don't know a lot about the Toyota tuning scene, if so, that's crazy cheap.

[Billman]

Sorry, i thought the price was for 1 piston not for 6!!!!! although that comment here is questionable: "High Quality piston set, same as what came in the 7M-GTE stock."
