Stroker build

I could not trust Izzy & Corry's work more, I've never seen that level of attention to detail. The E90 will continue to be double-tracked hard and if there are any issues I'll post them here.

The CF driveshaft is a thought but I've seen the numbers and doubt it generates more than a couple hp.
The car is still on a stock diff but when it dies we'll get a built one with a slightly lower ratio.

As it sits now I'm sure it has a 2 minutes flat at the Glen in it.

I've read you don't like using E85 because of availability but I'm sure this wonderful engine would love some 50/50 water/meth. Higher octane and cooling

I have been running water/meth in my n/a S65 for 5 years with the NLA Vishnu Procede. Aquamist is good — I use it on my turbo E36M3, but the controller is not a piggyback that interfaces with the factory ECU.

Do you think the do88 bits will still handle the cooling sufficiently? Certainly an awesome package, curious to see how it performs in your car now with the stroker.

This build is so awesome - definitely sold me on going this route after I'm finished with my E92 in class competition. Even will have the karbonius intake sitting in storage waiting for it. Not sure you can get any more fun then this on the track outside of somehow a E92 GT2 magically finding it's way into the garage. On the street - just wow, perfect build.

Dammit my number isn't even close to 47! Well we'll have to make do!

I'm curious about the cooling as well. I have the do88 which I had before as well as the BW/EPIC oil bypass which is new. I still have a regular coolant mix so there's always straight water + water wetter to reduce temps if needed.

I could not agree more with the fun part! This platform could not be any more fun, I love tracking it. The F80 CS maintains a lot of the fun factor but it sounds like a fart can while the E90 sounds so loud and wonderful.

If I could find that at the track maybe I would just for the cooling effect but as far as I'm concerned you're lucky to find regular gas at the tracks... it's sad but true

your setup sounds like the perfect one...

[6ixSpd]

Unreal! You've built the perfect stroker S65 IMO. Literally shifted the entire powerband up through the roof with zero downsides. Even the TQ curve is just bigger than before in all areas. This is my dream end goal for this car. One day... one day.

Take a bow.

I don't they'd have Meth at the track but that's something that you can prep at home with a topped off meth/water tank and you should be good for the entire track day. 50/50 water/meth isn't flammable so you can transport it mixed to the track also.

Or the easy way is to buy Boost Juice. It's a premixed jug of 51% water 49%meth.

Yep. I'm a fan. This is exactly what I had hoped was possible with these engines, and somebody finally done did it and documented it. This is my savings target after I get the rest of my minor bits done (roof, driveshaft, solid subframe bushes). CAn't wait to see how it holds up and what it's capable of on track - cammer S65 maybe a 15th bday present for this car

I can see this working with a setup like pbonsalb's, where it only injects meth sometimes.

Used as a straight fuel like most people like tuning for, like E85, it's impossible. We consume half a tank a session and the car is double tracked.

and I bet you can just use the 292 cams and Karbonius intake to make 420whp...

In the end this is turning out like the E46 saga... where at first it seemed like cams didn't do anything but with time they make a huge difference

With my E92 I know I might not be the fastest on the track - but you're going to be hard pressed to find someone get out of their car afterwards with a bigger smile. 4.6L has got to without a doubt amplify that exponentially. Couple of months ago was looking for another M car that would be mainly street but with a couple of track days mixed in. I love the F80 CS - just an overall amazing car & looks incredible particularly in SMB - had one local that had been sitting awhile but just couldn't pull the trigger. Sounds silly to say but the sound was a big reason why I couldn't do it - had a F80 comp with MPE and that didn't make it sound much better, only now just fart that much louder. Ended up with a N55 M2 - not the best sounding car out there but definitely much better than the S55. Just one of those silly things that makes me smile that much more while I drive it. Certainly wouldn't touch the sounds coming from my S65, let alone a 4.6 + karbonius + headers, but still makes me smile.

Please let us know how it goes with the cooling. Hopefully the temps stay under control for you.

Big single N54 is still my favorite 6cyl sound this side of an Datsun RB

Somebody needs to big single the S55 maybe it’ll help. That motor doesn’t need quad pipes either - one 5” grapefruit chute ought to do it

Kinda sounds like a 2JZ

A 5 gal tank in the trunk will fix that for sure. An engine like this is a shame to run on straight 93. Best of luck to you can't wait to see pics/vids of it running hard.

The F80 CS certainly does not sound well. It sounds purposeful and angry when driven hard but not good. In my mind it reminds me a lot of the E46 M3, that was never pretty but always purposeful.
What is scary is how fast the CS is. The SoloDL data does not lie, when you overlay the graphs of the E90 with a stock engine, full PFC BBK, MCS 3WR, R1 tires vs the CS with camber plates, front BBK and RE71 tires... holy shit. They do the same time but the CS makes the E90 look like it's turned off.

I wanted a SMB CS but ended up with white. It'll likely get swapped for a G80 ZCP or maybe a M4 GTS.

I'll make sure to update with cooling. Randy may drive the E90 soon as well, I look forward to his impressions.

Stroked or not stroked, I need those 292 cams...

Nowhere close... maybe on youtube videos but in person the 2jz is way more intoxicating.

I can see myself doing the 292 cams on the E92 with stock displacement... I can see it already! hehe

Put an active midpipe on. I had a custom single pipe midpipe made when I had my f80 with mpe, and it actually sounded good lol

Please don't get me wrong - the CS is an absolute beast out the door and still has a lot of untapped potential in stock form. I was very close to pulling the trigger on it, actually surprised I didn't. Also at the last minute decided I wanted a 6MT which helped steer me to the M2.

The G80 is very intriguing - can't wait to see what it is all about. But that M4 GTS though...

So has this car been tracked yet with the 4.6 engine??
