putting a BPT into a V6 model car?

[Gro Harlem]

Is this possible? Are the engine mounts in the same location? Would the transmission bolt up and all?<P>I'd rather do this since the transmission in the v6 models are g series, plus the cars have all the nice features and all . <P>Thanks in advance

From what I have gathered, its possible, but its more trouble then its worth.<P>Try searching next time too

[viocurse]

why are you all hell bent on searching? the f-body board i post at gets asked the same questions all the time, "which exhaust is the best" "which intake lid is the best" "what 1/4 times does a stock lt1 run", and you know what we do there... answer them. it's no big deal and it doesn't make us (the regulars) come of as being pricks. when i first logged on here, that's the impression I got from almost everyone here.

I searched and only brought up 4 cylinder related bpt swap info.<P>I asked braden and he said it is a better idea to do it on a V6 car since they have the g series, and the mx3's have more room underhood. I don't want to screw up my f/r weight ratio by putting a heavy KLZE in my car when I could get equal or more power from the lighter BPT engine.<P>Thats why i would do this, handling means more to me.

KLZE weighs the same as the 1.8L. If you are really looking to do the swap i suggest you talk to the member of the board by the name of Tim Harris. He's done the swap in reverse order so he would probably be the one to help

To swap a BPT into a V6 car, you're going to have to get basically everything under the hood from a 90-94 Pro LX [tranny, cross member, radiator supports, etc]. The BPT is probably heavier than the KLZE, since the K series are alloy, open deck blocks, and the BP's are solid deck iron blocks. I know the KLZE weighs about 380# with all the manifolds and accessories on it...how about the BPT?

[Gro Harlem]

i don't think the BPT weighs THAT much. I believe the G series trnasmission weighs 82 lbs. And the engine with manifolds weighs about 260-280ish.

Hey, search for a guy named Dave Lauzier. He did the K8-BPT swap a wile back. I agree with the rest, swap in the KLZE. Aprox the same price for the engine, and hella easier to install. Plus you don't have a turbo to mess around with.....unless of course you want one, then you can put the money you wer gunna spend on the v6-i4 conversion, and turbo the KLZE for nice HP figures

sorry to bring this topic up again. I have a GTR motor that I plan on swapping to my 93' Protege, however I'm still hellbent on finding out how hard it would be to swap this to a GS.<p>I want a GS for the obvious reasons: rear disc brakes, better steering ratio, power windows,mirrors, nicer seats, etc etc. As for why I'd want to do the swap on a MX3 instead of a Protege....well I just feel the MX3 is a more attractive looking car. I love the look of the exterior, there are MANY MORE bodykits available, and I like the way the interior looks (more modern). <p>However if I do somehow end up buying a GS, I would much prefer doing a BPT swap to it instead of a KLZE. Despite what many of you think, the BPT is much lighter than the KLZE. If the KLZE really does weigh 380 (sounds kinda high). I know for a fact now (since i got my motor shipped to me) that the BPT weighs under 220. They wrote 230 on the shipment slip and I know that the pallet probably weighed 10 lbs or so. Braden told me they weigh 190 lbs without transmission (just motor w/manifolds, turbo, and alternator)<p>Here are my new questions:<p>1: How many plugs is the V6 ecu? The BP ecu is 2 plug, and the 4 cylinder MX3 sohc motor is 3 plug. <p>2: Do you know if the engine mounts match up if I had the Protege mounts and brackets?<p>3: The GS transmission (at least i've read) is the same thing as the Proteges....but I havne't seen one to believe it. Do you know that it will bolt up to the BPT for sure?<p>4: What about axles? Wouldn't you be able to just use stock MX3 axles if you bolted up the G series trans to the BPT motor? <p>If the transmission bolts up (and uses the mounts to hold it in place) and the protege mounting bracket fits into the MX3's passenger mount, then this engine swap is about as easy as a KLZE swap. Only complication is the turbo aspects of it.<p>I plan to rip the old harness/ecu out and put a GTR ecu and harness in (already ordered them), along with a higher flowing fuel pump to keep from running lean, and a custom intercooler/downpipe setup.<p>Thanks in advance for your replies.

this all comes down to how mcuh money you want to spend the kl-ze swap will be cheaper then the bpt but if you want the most hp
the bpt is the way to go i havent yet seen a kl-ze turbo or any thing run 11's but a v6 model with a bpt modded ran 11's
but if you dont want to spend that much money go with the kl-ze intake header exhaust and you will be happy plus a 45 shot of nos

A KLZE swap will run you ~1300 bucks out the door if you do it yourself into a GS, and you'll run mid 14's in the high 90's, while getting 25mpg and not have to worry about EGT's or oil leaks. To each his own...

the sohc mx-3 ecu is only a 2 plug, i think the 94+ might be 3. but i know the sohc is only 2 cause i just swaped it for a bp 1.8l(escort gt) ecu and it worked fine

[Aston Wards]

?? my 91 V6 Presso is 2 plug too!

[Gro Harlem]

Thanks for the replies. That makes sense. Since its a V6, the bellhousing would accomadate that....stupid me.<p>Here are some more questions to build onto the original:<p>1: So if I swapped out the V6 and trans, couldn't I just swap a 1.6 SOHC crossmember, and engine mount brackets from a SOHC transmission, bolt them up to my G series 4 cylinder transmission and bolt it up?<p>2: if this somehow worked...Would the V6 axles fit into my 4 cylinder transmission? I would think they would...the splines are the same I think, but perhaps the location of the differential will be closer or more far away from one of the hubs making custom axles necessary (and possibly a SOHC shifter linkage?)<p>3: Is the SOHC/DOHC 1.6 passenger engine mount bracket idential to the V6 one? Or are they different?

[Gro Harlem]

Oh, and if i didn't already own a GTR motor with all the ncessary parts, i probably would do a KLZE swap.
