GM 3800 V6 swap

It looks like our host is doing V6 swaps now?

Cool ides.

The 3800 supercharged motor is pretty stout.

Anybody have any information?

What info do you need, I/Kent ave just about everything that is know/needed for the swap. It can be done for thousands less than the LS/LT conversions and still starts at about 250hp.
That's twice what most cars have to start with, I know , Except for the Turbos, but you don't have all the maintenance issues. We have Dyno sheets to prove it too.

Are you guys going to make headers?
And do the intakes swap backwards like the LS engines do?

wait a minute!

RH stated that V6 were not a possiblity because of vibrations induced to the drive train. Whats the bellhousing required for this V6 hrybridazation?

PORH. Those morons told me the 5.3l truck motor wouldn't work....

I'm not up on my v6 knowledge, but I think the newer V6's have better balanced and designed cranks to offset the vibes. Also there are these things called motor mounts to take out the rest of the vibes. BH's galore for those engine too.

yeah after some googl'ing i realized jeep guys already have an adapter plate made for their stuff that could be easily modded for our driveshaft.

The BH that I'm going to build an adapter plate for will allow for the I4, I5, I6 and can swap right onto the BH's for the V8's......FRH

I have done engine swaps into two MGB's, the first an Olds F85 Aluminium 215 ci V8 into a roadster, the second a GM 3.4 L V6 Crate Motor into a GT.
If I was to choose a motor to use again in a swap I would go with the V8........why? Smoothness.

I'm really looking forward to the LS1 in the 944.

I think the V6's would be a perfect match for the NA transaxle gearing.... a win/win situation in the 944 swap world. Not to mention the amount of work space in the engine bay would be rediculous. As for the Boxster conversion, someone is going to wake up and put the Grand Prix GXP drivetrain in one and skip the Boxster transaxle in one shot.

details man!

After I exhaust my stash of C5 BH adapters, I will start making them and divulge details at that time. The C5 2-piece BH's are getting hard to come by.

Turbo Buick Boxster. That has to be next.

Toss the whole Boxster drivetrain.....

Take a look at whats in your car right now. The I4 that's in there will just about rattle the cage apart if it weren't for the balance shafts that Porsche put in there (and they still don't take it completely out).

I looked into this engine briefly before deciding on the LT-1. Main things that made me go with the LT is you can find them very cheap, they're easy to work on, can get all the horsepower you need, the V8 is a very smooth running engine (the vibrations that were mentioned earlier) and I'm not taking much of a risk putting this engine in as so many people have done it before (This will be my first swap).

i have thought of this as well, or a ford 3.8SC...would like more details.


as for the gm atlas motors, the i-6 would likely be too tall without bumping up the hood

Bell housing adapter is already done for the V6 3800, I just need a donor car to do the install.
Anyone?


And if you need the hood bump I got that too.................

Too bad you're not closer to me, I'd give you the shell of my 83 that you could use as a mockup.

I just found this thread and what's funny to me is that last year I picked up an L67 (supercharged 3800) to drop into my 944. This seems like the perfect motor, it's compact, has good power, it's lightweight and will sit further back in the engine bay than a V8.

Let me know if you need someone to help with mock-up. I can fabricate parts and I've already got the 944 motor pulled and the L67 is poised and ready. I just need an adapter plate and to do more research to find out if my ideas for a clutch will actually work.

If you want, I could send you a deposit on the adapter so you can send it to me for mock up.

Your out of luck at the moment, I won't be selling the adapter OTC just yet. I will only sell it , installed for now. I need to make sure everything it proven to fit and function before I will sell it to the do it yourselves guys. I will tell you that the adapter can be made to fit the stock 3800 bell housing to the torque to with the right measurements and some time.

Anyone know what it costs to ship a 944 out to the states!

These people are often recommended:

howabout 4.3 vortec? make nice power, are ridiculously common, and basically any part ever made for an SBv8 can be made for the V6 as well. also considerably lighter than a V8, even moreso if you find some aluminum heads for the v6.

not to mention they sound like a detroit 6v92

Also not to mention They will rattle you car apart. Every 4.3 I have messed with has a horrible out of balance problem. I would not recommend it.

I had a 4.3 Vortech in a 94 blazer that wasn't too bad on the vibes. As I recall they put balance shafts in them that year, but then again, that Blazer got a V8 lodged in it and I could do donuts in that 4-door SUV hehe

any news on the 3800 swap? found a TON of these things at the boneyard the other day, i could have a complete motor for $230

also...
