Disclosure: I am not a DIYer. Hell, I rely on the technically-savvy to do even the most minor of things to my car...hence, the ignorant question that is to follow.

How involved a job is it to swap out the NA engine in my C4S for a TT engine? I thought long and hard about a TPC SC and decided against it. Frankly, by the time the TPC SC is done properly, you're looking at $10-15k. I don't trust LA Porsche dismantler for much of anything (prices included), but this post got me thinking of whether others have held onto two engines (a NA and a TT) in lieu of a TPC SC.

Probably cheaper, and better, to just buy a TT.

 

haha, fair enough. It's always been an intriguing thought to me because of the whole "the C4S is a Turbo without the Turbo" bit (i.e. it has the brakes, the body to accommodate it, etc.).

 

^Yes, sell the C4S and buy the Turbo. The delta will be about $20K....give or take....for a like-like comp.

 

What if I want the TT engine AND the option to switch back to the NA? :P
What sort of labor are we talking about in terms of swapping?

 

Sell the C4S, buy a TT. It's not just the engine, it's the gearing as well that's different. Among other things...

 

Stay off boost! 282 HP w/o boots. With boost, hold on. LOL

Guys can do engine-out and engine-in, in 10 hours. For the the same car/engine.

Most indy shops quote 20 hours when they do engine out work for R&R.

So, I'd figure at least 20 hours at $120 per hour = $2,400 MINIMUM.

 

It has been done before; search the turbo forum. Big Bird is just one of them....

 

Or supercharge it.

Finding a good TT engine will be a challenge, i have seen average ones with highish mileage for $22k to $25k.

You will need an ecu and wiring harnes if you cannot find an engine with one, then there is the labor etc.

I would say you are looking at about $30k all in for the conversion..... Put that and your car together and you will get yourself a very nice TT...

 

"Theoretical" question answered: not worth it.

Very interesting reading how much a re-gear can transform a 993. I wonder if a regear would accomplish 80% of my goals without having to mess around with superchargers and goofy ideas like this turbo conversion...

 

Or convert to a C2S.

 

I like the 4.

 

re-gear would be the way to go....ask that Steve fella...lol
