Several years ago, after 20K miles running around with the ESS 600 and 650 SC's, my M3's rod bearings spun and damaged the block and crank. Looking at the replacement costs for a stock motor I decided to instead have the motor rebuilt, stroked, with proper clearances on the crank and rod bearings. The goal I wanted was a strong motor for FI, stroked for torque to off-set the convertible's added weight, to run at a reasonable boost. I wanted to utilize the stock fuel system. Try not to complicate things too much. Reliability and longevity were the goal. Name: M3 TT.jpg

I did drove the car from LA to Denver, about 1,000 miles. My intentions was to drive back to the East Coast. I went easy on the motor all the way. Along the way, going thru California to Nevada, the outside temp was 112 F. Air Conditioning was on at it's coldest setting, 60 F, with the engine temp running no higher than 225 to 228 F. Posted speed limit was 75mph, while Nevada and Utah was mostly 80mph. Engine temp was typically 210 F. Gas mileage came out to be almost 23 mpg (logged). Gas is also a dollar less (still only 91 oct.) once you leave California! Around town I'm getting about 14 mpg, about what I expect. Unfortunately the alternator quit and I had to ship it back to Gintani. It was cheaper to ship it back than have the local BMW dealer install a new alternator. BMW wanted over $900 just for the part plus they estimated labor costs around $1,200 + since the sub frame has to be dropped to even get to the alternator. (there simply is no room left in the engine bay with the turbo set-up, everything is extremely tight!). Gintani fix the car at no cost. Then it was shipped to ACM in New Jersey.

Although it took an inordinate amount of time to complete, break-in, and test the car, the final outcome is a well build, solid engine and turbo system with the kinks worked out of it. While I have had it home only a short time I can report that the engine and TT system work great and the car's performance is everything that I had hoped for. It pulls "like a angry pit bull" and pins me in the seat all the way! The engine bay looks OEM. Boost come on strong and quick, with full boost at 3,000 rpm. Rear wheels spinning through the gears. Fair to says she has 600+ whp on stock fuel system. The exhaust is very loud (almost too loud- attracts attention ) when fully open, yet quite quiet when the valves are closed. Still drivable around the neighborhood. Open the exhaust valves and it's definitely louder. The whole TT set-up is definitely not a simple boxed kit you can buy and install yourself. There no more room in the engine bay, everything is very tight. Hopefully next spring I'll have the car Dyno'ed and numbers to put up for everyone's view. I still have a Arown to install and I'll also put on some fatter tires (she needs them badly!). In the mean time I'll just enjoy her before winter arrives.

I'd like to thank ACM and Gintani for all the work they've done in helping me put this build together. She's a beast. She'll keep up with the SC'ed coupes and sedans and then some. And it's one of a kind.

What's the new stroke for the engine?

From his build list I suspect it’s not stroked, but instead overbored to 4.2. He did not mention a new crank but did state stock compression, and didn’t want to overcomplicate the build. Just my guess.

///M Power-Belgium · 10-23-2018, 02:01 PM

Would love to hear a video from this amazing car ...

DetroitP · 10-23-2018, 02:39 PM

Very nice build!... Anymore pics of the engine bay, and TT setup.
Any idea what is the Rod to Stroke ratio on the 4.2 stroker?

Yes. I'll post what I can.

Gettig the information from Gintani and confermation

m3jala · 10-23-2018, 03:22 PM

In my mind you can't beat the sound of the v8 turbo. I have seen a couple videos. This thing must turn heads.

mkPOTO · 10-23-2018, 03:49 PM

VIDEOS??

Epic build, my favorite e9xM car.

Unless the motor was sleeved to under 92mm and the stroke increased to add back up to 4.2L.

I believe VS Motor did this on the crazy TT S85 they built.

schnell1982 · 10-23-2018, 10:46 PM

Awesome build !
Did you upgrade the DCT clutches or running stock ?
Also is your engine cooling system using any upgrade coolers ?

Stock transmission. Hopefully there's still good life left in them.
Have a CSF radiator but it wouldn't fix with the turbo setup. Did install CSF oil cooler though.

Dang you crazy.

Congratulations on this beeest.

Redd · 10-24-2018, 07:55 AM

If I'm not mistaken this build has taken quite a long time? What's it been, 1-2 years? Glad it's out tho. Looking forward to seeing the numbers!

Yeah, it took forever. Partly changes, partly Gintani, partly finances. Lots there, took time.

Is this motor sleeved?

Nope.Gintani no longer sleeves builds that are for FI.
Not enough meat in the walls. They've seen the heads Crack on some SC ones.
These are Alusil block and pistons. Soft break-in on the motor.

Never posted a video either. Guess I'll have to learn.
Weekend approaches...

That's a statement I couldn't agree with more. I'm not a fan of sleeving any of these given the cylinder spacing.
