6 cylinder swap Vs. supercharger

[AlaskaBlue]

That is a really good price.

My take on engine swap vs. S/C. If it is fast I don't care. All it has to do is meet the owners wants.

Now let me get this straight. Their are a few things that really confuse me about swaps.

1. The computer just goes in place of the original one?
2. The fuel injection and all that comes with the motor?
3. Needs a 6 cylinder radiator?
4. Other than those it basically bolts right in?

[Dredder]

1. The M3 ECU will take its place. My ECU is model 413.
2. You need the complete motor (alt., power steering pump, A/c Compressor, Intake Manifold, Fuel rail, Etc.), wiring harness.
3 You really don’t need a 6 cyl radiator. If you live in a hot environment (e.g. California, Florida, Texas) then I suggest you do. I use an aluminum radiator from my 318ti that was upgraded during my power search for the old M42 power plant.
4. All E36 motors are interchangeable. You just got to find the right combination that will work for you. Try searching for all the required material for the swap. The most important part for making your ///M engine cool is the 80C thermostat.

I am not deterring anyone from getting a DASC. If my goal was to have max power of around 160wrhp then choice would be DASC. Cheap and reliable and can be installed easily.
I just want you guys to remember that if you’re trying to get the DASC to compete against the ///M, then you will be very disappointed. The entire amount you have spent to get the DASC close to a stock M3, you have already spent more money than if you would have just done an M3 swap. By that time, your stock m42/44 will require additional internal upgrades to push more HP out of that power plant, when you can have ///m3 power plant that can give you more than 450rwhp on stock internals with the help of FI and low compression HG.

The most important thing to remember about this particular thread is “WHAT IS YOUR GOAL” “WILL YOU BE ABLE TO ACHIEVE IT WITH THE CHOICE YOU MADE”

SWAP vs. Supercharger is like night and day. It depends on what you want.

I think fundamentally the choice is based on what is most important,
Ultimate power, (Swap) or an edge in economy (fuel) with a edge
in agility from the lighter weight. Head to head the 6 will beat the 4
for say endurance racing, But in a autocross I would bet its going to
be statistically even.

As far as reliability I don't believe the SC is any less reliable than the
M3 or M52 swap. there are plenty of supercharged rigs out there that
go 200K miles with no problem. ANY engine will fail if driven wrong.

The M42/M44 engines are very very tough. BMW didn't skimp on their
development. And because of the length of time the M42 was built
they definately have the bugs worked out.

Most M3 owners I know have a fairly high cost of ownership do to
wanting to keepp the engine at top performance. Not because they have to.

That's it in a nutshell!

I can't beat everyone all the time, but I can enjoy beating some of them some of the time.

Same here, I sometimes get beat by my friends Turbo S Beetle. It has the Audi TT motor in, plus it's chipped so it's pretty quick. Nothing like getting beat by a Beetle to put you in your place!

I got my doors blown off from a stoplight by an F250 yesterday.....
and I do mean blown off. Big Block 4 door long bed.

Tough to beat pure cubic inches.

I saw a F350 turbo diesel with propane injection beat an NSX, now that's funny! HUGE cloud of black smoke and 1 pissed off NSX driver.

This guy totally took my lunch money ,,
don't know for sure what engine but it wasn't a deisel or a diesel.

Imagine the look on that NSX drivers face... - - -

[Silver00spike]

well, I don't know if you want to say that going DASC is reliable. My 109k engine leaked coolant about 3-4 times, each time it was some plastic coolant to engine adapter, or something like that that costs $40, and plenty of labor because they have to take the blower off to reach it. This was one of my main reasons for wanting the swap

I was at the New Hampshire drag strip opening night earlier this year and there was a F-350 turbo diesel with the Banks power chip or something like that. Well it was running low 11's high 10's. This thing was just hauling a$$ down the line,nothing that went up against it could beat it.

Im tired someone can do the math for the discounted rates.

From http://www.bavengine.com/engine.html:

Their performance M3 engines are $6,622.

Now that's rebuilt. I understand taking 50% off of $5400 to get the $2700 figure, but that's for a used M3 engine, therefore not "high performance". I believe "high performance" is only done to their rebuilt engines, am I correct? From reading their "used engines" page here I see nothing about the "high performance" option, which increases the stock horsepower by 20%.

Not knocking at all, just trying to figure out what you mean. Did they tell you that they do their "high performance" option to used engines? If so that'd be excellent!

S/C is the way to go with a Ti. Its not really the same with a six because your going against the true nature of a Ti . I mean if you want m3 power get a M3 simple is that.the money you spend on your Ti and the swap could get you a good M3.

if the choice I would have gotten a 323ti also.

and I got my ClubSport, over a 95 M3 I was looking at.

I like the style of the Ti, it's like the 2002tii just stands out in a group of BMWs

but since I am working with a factory four, I decided to go f/i on a built engine, rather than swap a bigger heavy powerplant into it.

I may pick up another 95 Ti for a swap in a year or so, but for now it's going to be boost that runs the CS.

thats $1300, with the tranny.... How does it come out to $10k installed? Is there a lot more to the swap? If not, I can win that M3 engine, and throw it in my TI. I have the blown head gasket $160, need a $400 valve job, $40 new water pump, and to have my #2 cylinder sleeved $250. It would only be about $500-$600 or so more for the M3 engine, now would be the time to do the swap. and maybe even ebay the engine with a blown head gasket, and get a couple hundred.

With all the crap included, how big of a pain is the swap?
