Post subject:  Engine measurements
Anyone have the measurements on the /6 as far as the overall length and width of the motor. I have been contemplating swapping one into my 2004 Chrysler Crossfire since my transmission went out and is so expensive($3000) to replace. Putting the Slant 6 in would be cool especially since the factory drivetrain is Mercedes Benz and an electrical nightmare for modification.

Interesting idea, but that's not going to work, in about three dozen different ways. Some of them have nothing to do with measurements and everything to do with legality. Unless you aim to create a driveway monument not driveable on public roads, you're definitely on the wrong track. Hit www.car-part.com and find used correct parts to fix what ails your Crossfire.

Crossfire is a mercedes car of odd origin. Trans mercedes while chrysler used their mopar 3.5L in it, not too common kind. Other options was 2.7 and 3.2 more common in other chrysler cars. RWD car btw.

Body is mercedes's. Crossfire is based on SLK mercedes but not quite.

Start measuring the engine bay first. Info is in slant http://www.slantsix.org/forum/viewtopic ... 46&start=0

Cheers, Wizard

I live in Alabama, legal here is having your vehicle registered and having minimum coverage liability insurance and a Drivers License. There isn't even any emission testing.

Thanks for the link Wizard

Sure, not now. Not yet. But there will be, eventually. And that's just state law -- what you propose is Federally illegal.

Texas sounds to be similar to Alabama. Some counties have
more strick inspections. You can build just about any vehicle
and register it in Texas as long as it has proper lights. I'm not
confirmed that a home built vehicle in Texas even needs a
windshield.

A motor swap on a late model car, probably has to pass basic
smog in an urban area, but I doubt if they care what motor is
in it. Most rural areas in Texas don't mandate the smog tests,
don't even open the hood. Things might change, but I've not
heard of any new rules.

Gosh Gee Golly Gee Whiz Gee Willikers I sure hope I don't get stopped at any federal checkpoints eh. LOL dude you are too funny, thanks for the laugh, for a second there I thought you might be serious. :roll:
BTW fair right and legal are not synonyms. If you are part of the welcome wagon you failed.

Maybe you can swap a T5 into the Crossfire. Cars like that will
be a novelty in coming years because there are so few of them.
It'll be hard to find body that trim parts for sure.

I don't know why it costs $3000 to rebuild the transmission. I'm
keeping my older cars as long as I can. The new automatic
transmissions are pretty good performers, but cost so much
to repair.

Well just like the other Chrysler rear wheel drive cars the Crossfire probably runs the goofy W5A580 German auto trans that is really weird, you cant even check the fluid because it is temperature sensitive. Chrysler is trying to get rid of it as soon as possible according to allpar, maybe with an 8 speed.

I am pretty sure that is legal up here in Michigan, as long as it is registered as the original chassis with insurance and up to date registration. I have seen may of old Rams and Fords built this way, and quite a few oddballs running 4.3 GM V6s in newer Jeep Wranglers. I would look into it more and see if you could find a wrecked car for the trans, or shoe horn a manual like Tim said.

The real reason I am doing an engine swap is because there are a lot of limitations with the stock electronics. Mercedes' ECU's have a lot of other processes going on in the ECU than just calculating injector pulse width and timing. It is constantly checking for possible errors in the system so hiding the boost from the ecu was more than just voltage clamping the map sensor. In the end I was able to run 10 psi on the 10.5:1 CR motor with an Eaton M90 and methanol/water injection. The car ran great for about 8000 miles until the extra power consumed the clutch packs and bushings in the transmission. A six speed was an option in 2005 and later models but swapping the tranny in wouldn't eliminate the limitation I hit with the electronics. Not to mention the computers in the car have the VIN embedded into them and without MB software you can't just swap a transmission without swapping the supporting hardware and software. Its not impossible just extremely expensive. Swapping in a /6 with FI and a Turbo would be much more manageable IMO.
Some people on the crossfire forum are having problems getting body parts for their cars already. Chrysler is currently negotiating with parts manufacturers to produce replacement parts or so they say.
To my knowledge emission inspections are limited to checking the OBD port for fault codes and checking the emissions from the tailpipe under various conditions. You pass both of those and the car is legal.

If you do this take lots of pics and keep up posted. Sounds like a cool project! 8)

No, that's still quite illegal. At that point it's just sneaking past an inspection.

This still seems like it wouldn't be worth it. The rear end of the slant will be about where your cd player sits. Might be a bit uncomfortable to ride in. Run the six speed and be happy with 10 psi supercharged. JMHO.

I would say run megasquirt but I wonder about things like your gauges working and don't know if the stock six runs any advanced engine tech like variable lift or cam phasing etc.; which you would have to mechanically lock out.

It sounds like money isn't a problem.... Why not shoehorn in a 6.1(or 5.7, or 392, or 7.0) new hemi? Plenty of aftermarket management options exist for it, as well as a 6 speed.

If money is an issue, I don't see the relative "cheapness" of the slant six saving you any in the long run. You'll probably be nickel and dimed to death...

Okeh, well even if we go on the assumption that your knowledge is correct — which it isn't — how were you planning on passing the OBD code scan with a slant-6 engine?

Hey Ramming speed I say do it. Us back woods hicks have to stick together.

Ok 904 trans front of bell to back of output shaft 31 inches. Front to back is 30". Output shaft sticks out tail shaft 1".
Slant block is 26" front to back. Other engine measurements are 15 1/8 across the block 14 3/16 c to c on the lower mounting holes. Block is 13 inches tall from deck to bottom of the main caps. Head is 6 1/2 " from deck to top of rocker stand.
Hope this helps,
Frank
