Do the best engines always get paired to the best transmissions, or is there always room for improvement?

If you could bolt any transmission to any engine, what would your dream setup look like?

Yamaha Two Stroke Twins (RD & TZ); because H-pattern synchro gearboxes are abominations in comparison and a rev happy two strokes spinning to 12K are glorious. This is also the reason I like motorcycle engined cars.

If I have to pick a common automotive combo I'd go with Miata engine and gearbox. Nice gearbox with a revvy motor.........I especially like 1.6s.

The TR7/TR8 gearbox is phenomenal, unfortunately I don't think it was ever mated to a really good engine.

Twin turbo 555-ish " BBC/BBF and a Lenco. May or may not include a Bruno for the inbetween....

TKX bolted to the back of an LS.  

Not a cheap proposition, but I have learned to be blasé about  6 speed manuals.

 

Because of a current thread re roll-your-own mid engine, I have become fascinated with LS to Audi conversions. Fascinated, but not sold on for various reasons.

That sounds like a fun combo to me.

Depends on what I'm dreaming of building.  Right now, my dream engine/trans combo to stuff a Cummins 12V backed by an Allison 6 spd AT with a dual range transfer case into my 1992 E350 to make it 4WD.

6.0 Jag V12 and Saenz 5 speed. ( dog ring) 

I just love shifting dog rings.  I feel like such a brute doing those clutch less shifts with my throttle foot flat to the floor.  I understand they can even make it sequential rather than H pattern. 

  The 6 liter would be offset ground  and liners taken out to .100 to yield a 7+ liter engine.     With a pair of T4 turbo's and E85 as fuel   1200? Hp!!!!!

4G63 to a real mid-engine trans with decent highway gears and still strong enough to bang out quarter mile passes all day every day.  

Even more cooler is if that trans has a provision to run a front transfer shaft as well.  

Yet even more cooler is addressing the coolant situation so the 4G is piped like a proper inline RWD application and not a FWD application turned sideways.

I'll just leave this here. Fun starts around the 30 second mark.

This, mated to a fancy BMW dual clutch transmission should do just fine

My lastest 'project' has this setup, and I am digging it.  Very nice combo.  Mandatory new project (the $8K C6) photo:

The BHW and FS5R30A going into my Mercedes is pretty fantastic honestly.

OM648 backed with a ZF S5-320z would be a close second

I also dream of a Duramax(ask curtis which one) with a ZF S6-750 and a manual shifted transfer case for a snow and highway capable RV dream build.

I really liked my Yamaha FZ1 engine and it's six-speed box. Strong bottom end pull, very strong mid-range, and crazy top-end. You could pootle around town all day long shifting at 2500 rpm, or let it rip to the crazy redline. The gearbox shifted like butter whether you used the clutch or not.

M275 with a robust 6 speed manual. Or even better, m120 with itb's and said transmission.

It was a factory pairing, but I keep coming back to the B16A/S1 combo that I had in my CRX. The B16A had all the revs–especially after its new computer–while the S1 had that low fifth gear. To quote JG, it was like driving an impact wrench. 

Terrific on track. Not a great highway car, though.

Where is the TKX mounted, behind the engine normally, or at the rear diff like normal for a C6? 

Interesting project.  Is there a build thread on this?

I have to say I'm quite happy with the already existing marriage between the N52 and whatever the code for the 6spd manual BMW uses in them.  Silky smooth bottom to top.
