TVR Speed 6 Swap?

Recommended Posts

ryant67    6

Are spare parts available, and what is the cost of them like?  That would be my first concern.  TVR has changed hands, shut down, reopened, etc, quite a few times over the past couple decades.  Could lead to some headaches when it comes to support.  Would make for a pretty compelling swap though!

A notoriously unreliable engine, that's never been imported in the US, with no spare parts at all, no support, and never been attempted before...

 

I don't think I'd file that one under a really good idea.

 

Also that 3750 pounds doesn't get you a transmission either.

 

If you're looking for the highest horse n/a straight-6 240z build you can do, I'd probably go BMW instead. You'll end up saving thousands and tons of tons of time as someone's already done it before.

If you're interested in doing that, I'd suggest starting by reading everything posted in this build thread before you start.

You will absolutely need to be able to fabricate or be able to spec & acquire custom engine & transmission mounts, get a custom driveshaft that mounts to the BMW flexdisk and whatever diff you plan on running, and you'll also have to deal with BMW's anti-theft software in their ECU (so running a standalone ECU is probably going to be your best bet). 

 

It can be done, and as that build thread proves, it can be done cleanly. Just be ready for a lot of work. It will be very awesome if you pull it off though.

Meh, all those issues with the S52 and S54 have fixes for them. The connecting rod bearing issue was only on early early models of the E46 M3 and was a factory warranty issue. 

 

The only really crappy issue I know of is the high pressure fuel pump on the N54/55. I don't believe BMW has ever addressed that issue even to this day.

 

But overall I will agree that "German reliability" is the greatest hoax ever pulled on the American consumer.
