Hello everyone. Its been a while since I posted in the M3 forum. I bought an M5 that ive built and since its going back in the shop i guess ill be needing a beater for a while so! Without further ado.

I got a E92 M3 with a spun rod bearing for around 10k and dropped it off at BPC. Plans for it will be:

Phase 1:
New motor
Vac Rod bearings (installed when used motor arrived)
Stage 2 Harrop Supercharger
ARH Long Tube Headers
ARH Full Exhaust
Suspension
Wheels

Phase 2:
Forged internals
Ssp clutch pack
Full gut
Sparco EVO ii seats
Full roll cage
Sparco steering wheel
Liberty walk kit
Maybe color change
Forgeline wheels
MCS suspension
Aeromotions S2 dynamic wing
Front splitter
Rear diffuser
Carbon fiber roof conversion

Oem wheels with tires will be for sale.

I think there's a few things here that don't make sense. If you've got an engine with spun rod bearings, the crank is most likely dead and needs to be replaced. Spun rod bearings are about 50-50 putting micro cracks in the crank or damaging the journals beyond repair. I hope the shop isn't one of those that will rebuild the engine without honing the cylinders and putting in new rings. Assuming both are true, you're already at the same price as building a new engine with forged internals. So might as well do that first and get it out of the way.

But since you mentioned doing the engine twice, would you be thinking that because you want to drop the compression at the same time? If not, no point in building it a second time. Again, best to do that first and get it over with because the cost is the same.

Now, if I had that second point right, then I think you're choosing the wrong supercharger. Not only will it fail to provide the boost required, but I don't know of any tuners that can tackle a job like this with that kit. Before anybody goes back and forth on that point, I'll stand by both comments.

If you're really into doing this project yourself, hopefully that's food for thought. If you're looking for getting up and running quick, then I might have another solution for you of a complete low compression motor with forged internals + supercharger kit that's never been run. I think it might also be the same price as your phase-1 alone if the guy's as motivated to sell as I think he is. If that sounds like a direction that interests you, PM me and I'll send you the guy's contact information and you can talk to him directly without me involved.

What doesnt make sense to you?

I already bought a used engine. They went in from under the motor and replaced the rod bearings so i dont have the same failure with the second engine. Its already in the car and running. As i stated i have a previous M5 build with them that takes priority so i need a beater. Full engine build not part of the plan right now.

This "shop" that you speak of is called Bimmer Performance Center and they built my custom Borgwarner EFR F10 M5 which is about to crush 1000 rwhp. So no i don't think they will forget about small details.

After we do this and break the half mile record for the F10 M5 then we can focus on turning the E92 M3 into a Full on track rat. Which is why i said forged internals after phase 2.

Supercharger is already on its way. Should be posting pics next week. BPC is awesome in getting this car up and running so fast. By the end of next week we should have a Harrop M3. beater life.

Pretty sure just like everyone else its just a smaller pulley to increase boost a bit. And a different tune.

Last we heard from Harrop is that they are still in testing.

If they really sent you a smaller pulley and revised tune to go along with it then I am super excited to see what you make and at what psi.

No, you can't run a smaller pulley. It won't fit. Stage II is still in development... waiting for car to hit dyno.

Thanks for clearing this up. Seems like everyone is hot on your ass about this stage 2 kit

It's coming - we're testing with different injectors and MAP sensors. But mainly waiting for Harrop to have car strapped to dyno. My cars been at the bodyshop for 5 months and should get it next week. Although they've been saying that for weeks... the 600+ CC injectors are waiting

If you want to raise boost you'll have to change the crank pulley as the one fitted on the blower itself is pretty much the smallest it can be.

Nice build.

To be completely honest we opted on stage 2 because we were told it would be out in 2 more weeks and that the supercharger is not increasing in size. Were not trying to break any record as far as power goes with this platform because it will be meaningless as most SC kits fall around the same power level. 500 rwhp and 320-380rwtq. The goal is to build a beater that will eventually turn into a track toy. I already have an M5 that goes 169 mph in the 1/2 mile so i don't need a fast straight line power M3.

I'm not sure who told you that from Harrop as it's not the case. I did tell Dan that Stage II would still use the 1740 blower, however.

Well i'm excited either way. This post wasn't intended to piss anyone off or cause stress for harrop or Mbenvo. It's s simply a "I'm building an M3, this is the shit thats going into it, have a nice day". We decided on stage 2 simply because it was an option. If Harrop decides they want to wait another month, another year, or hell just never releasing stage 2 in the first place... I don't really care. I just want a raw S65 M3 with that pissed off stray cat under the hood sound I'll settle for a stage 1 roots over centrifugal stage whatever any day of the week. Stop waiting people. Yolo

It's not a matter of causing trouble or being upset... simply trying to clear up miscommunication. If someone told you that stage II was being released in two weeks and you purchased the kit on the basis of that (which is what you said right?) then that should be cleared up so others are not confused.

Stage II is in development and has no set release date at the moment.

This place is great with engine builds and tuning. I saw your M5 conservatively put down 807 HP at the wheels in their shop, that thing is a beast! Can't wait to see how this comes out

Please Define "Beater" this Build is $$$ so I don't understand the term.

To be completely honest we opted on stage 2 because we were told it would be out in 2 more weeks and that the supercharger is not increasing in size. Were not trying to break any record as far as power goes with this platform because it will be meaningless as most SC kits fall around the same power level. 500 rwhp and 320-380rwtq. The goal is to build a beater that will eventually turn into a track toy. I already have an M5 that goes 169 mph in the 1/2 mile so i don't need a fast straight line power M3.
