I need to replace my OEM one, and figured might as well upgrade, but I've read that some skid plates like Turner Motorsport's don't fit due the location of the Harrop supercharger intercooler.

Bunch of people running it, and no issues with the Harrop kit.

I agree. Can confirm that the Harrop system, Mporium skid plate, even the Do88 radiator and oil cooler fit.

This is exactly our set up. The undertray actually brought the oil temps down a tad, which was an unexpected but welcomed benefit. Also love not scraping the sides in driveways.

Sounds like this is the answer. Would love a bit more clearance, and dropping the oil temps is always a plus. Thanks all!

Same setup here, just swapped the Do88 radiator for a CSF, but still have the Do88 PS, DCT, and oil coolers with the Mporium undertray. Oil temp sits around 220F on the highway when it is 100F out here in the TX heat.

Curious why you swapped the Do88 radiator for the CSF radiator? I have been considering getting the full Do88 setup.

I had one of the early Do88 radiators and the fitment was a bit too wide, so rather than fab a solution, I had the shop swap it for the CSF. I have heard the later ones have fit well, but mine was off and I didn't have time to fight to try and have them ship me a replacement.

FYI to those who have made deposits, the ETA is November instead of October.

Sorry - just got word!

We are in the process of building a 4.4L stroker and are thinking of putting it in a Z4 Coupe with the Harrop. That would be one fun track car!

Can you provide any details on the engine build?

Idfkman · 09-03-2021, 11:54 AM

Any folks running this kit with high mileage with success? I'm at 145k and debating if it's too risky.

RB's done 10k miles ago and all maintenance done to a T.

Sorry for the slow reply here.

It's a 4.4L Marine Crank, Arrow Rods, CP Pistons, Dinan Valve Springs. I bought the engine from one of my best friends that had it built about 5 years ago. He ran it for approx 5K miles, and then with an ESS kit for about 2K miles. Then the headgasket blew and after disassembly it looks like a sleeve dropped. Not sure if this was a machining error or what happened there. Trying to decide whether to deck this black and use a thicker headgasket, or source another block, have custom pistons made to spec, and then reassemble. Not a huge fan of sleeves and would prefer not to use them - although it's the easiest way to get this motor back together. Going to table this project for a bit and sell a few cars off to make space for the build.

UPDATE FOR THOSE WITH CURRENT DEPOSITS

Just to update everyone waiting for a kit that have made a deposit - you may have received an email that your order is on hold. This is because we had to move the kits out of our processing queue. The ETA for the kits is still November. you can ignore the email you received. You'll be contacted in October to finalize the order.

The following list are those that have deposits in line (just initials) - if you have made a deposit and you do not see your initials on this list, please contact us - although it should be a complete list:

1. SD
2. JH
3. GA
4. TL
5. AR
6. NN
7. RO
8. JR
9. AA
10. DS
11. PE

Thank you - it's going to be a fun November provided kit production continues as planned.

Can anyone confirm if Eventuri intakes will fit with the Harrop plenum?

As in the air box or the elbow? The only elbow that'll fit the Harrop is the rubber one supplied.

As in the air box. Thanks for the heads up. I assume the Eventuri Air box lid should fit no problem though?

That part is oem BMW for Harrop. So yes I'd assume it works without issue.

Just an update for everyone.

Looking like Early to Mid December is being targeted for delivery. We will reach out to everyone the first or second week of November for any balance due.

For those looking to get the kit, we are adding those interested to a waiting list for when the next production run happens. Please send your Name, VIN, Address, Phone, and Email to sales@bpmsport.com to be added. Thank you!

BPMSport · 10-28-2021, 10:29 PM

Hi everyone, unfortunately just received the following from Harrop:

"Unfortunately, since we spoke there has been a further update and delay on the m3 kits.

Due to some compounding delays on parts, our best estimate for scheduled build time is now the week of 20/12.

However, there is a risk that this may move to January/February due to these compounding delays.

Also, note that the currently scheduled build week is the last week of our production schedule for the year and if the kits were to be completed, we would not be able to ship them until we return from the holiday break in January."

Sorry for the delay.. they will come, just very hard to acquire due to the present world situation.. I will keep this thread updated with any further news.

drwankel · 10-29-2021, 09:57 AM

Question for everyone here. I noticed that the 390MM 3/4" rubber hose that goes from the bottom of the intercooler reservoir has a pretty noticeable kink on my car shortly before it connects to the pipe at the front of the car.

In looking at it, it honestly seems like the hose is too long which caused the kink. I remember at some point some people had mentioned they had done some trimming on hoses when installing the kit. Was this one of the hoses that some people ended up trimming?

I'm contemplating cutting out the kink and putting an elbow there, or replacing the hose entirely, which I think is just bulk 3/4" heater line. It would be helpful to know if others had fitment issues with this line, as I decide what to do here.

I didn't do the install of the kit- and am kind of baffled how I never noticed this until now. I've been in and out of the engine bay plenty since I had the kit put on a year ago.

Took a couple of pictures real quick, lighting isnt great.

Yours appears routed differently to mine. Hence the kink in yours as it turns back towards the cylinder head. Mine runs straight along the chassis rail back to the inter-cooler reservoir tank.
.

Mine is routed the same. Straight down

drwankel · 10-29-2021, 01:40 PM

Thanks all. I think I have what I need to proceed here.

drwankel · 10-29-2021, 02:07 PM

Also looking at it again- my connection on the metal pipe doesn't seem very far in.

The hose for whatever reason seems too long. I think the answer is just to replace the line with some bulk 3/4 heater hose and get it set correctly.
