B-Series swap begins!

[thegreatdane]

i'd like just the mount kit... i like the a, but the be is better...

what about something like a j swap? i mean, a v-6 might be attractive in this car...

lol, actually, i believe there is enough room... i would like to measure it, though...

You're right there IS room.

[racetek82]

Having room to fit a V6 into a 3G is not an issue. The real problems come from lining up the axles, having room for the headers, radiator, etc. Add to that the fact there aren't many manual V6's out there, and you will need to change up your shifter / clutch setup to make it all work. Given the weight of and ony moderate power, a V6 just isn't worth the work. I rather have a built B or K series motor with more power and better handling for about the same money and headache.

[Vanilla Sky]

i just like the nice flat power band a turbo 6 would give ya... i wouldn't care how cramped my engine bay is

[ICEMAN707]

Yeah you also have to take consideration the weight of the v6. It would screw up your weight distribution and your handling. Unless you're going for just a drag car. Even so, the 3gee front suspension can't take the weight of a v6. That was the problem they had with h22's in crx's. They haul ass in drags, but they suck at autocross and circuits.

The heavy load up front will cause tons of understeer. Furthermore, the added power up front will cause the front end to lose traction too easily. What you have is a car that goes fast, only in a straight line.

Also, putting in a V6 will require different locations for mounts. Modern day cars are designed from the ground up as an integrated structure, and this includes the engine. Moving mounts around causes the structural characteristics to change. Furthermore, it also increases the chance of a screwup happening. At least if you stick with a Honda 4 cyl., you still have the same 3 mount configuration. (The b-series uses a passenger side mount whereas the A20 uses a front crossmember mount.)

[racetek82]

Cramped or not, if the axles and headers won't fit, there's no point to a V6....

We had a member on the acura legend forum that put a G1 v6 in a 88 civic hatch. He had no problem with the axles, because he used the legend front suspention. I think the hardest thing he had was putting wireing in the car and fitting the radiator in with the engine. I can't find the thread, because the search function is messed up on the forum right now. Looking at the engine bay of the accord it seems to be mutch larger than the civic. so I think with the skills that you have, a v6 swap would not be so bad. The one thing would be the weight difference, because those motors are heavy as hell.

[Vanilla Sky]

well, the exhaust manifold isn't a problem... just make a new one... as for the axles, if i'm not mistaken, the 1g legend has a similar chassis to our 3g33, so i don't see the geometry posing a serious problem there...

[ICEMAN707]

i don't see the point of getting a v6 from a 1g legend. that's the same as having the a20 with little or no aftermarket support and you have nothing more to gain. that would be a waste of time and money. you're better off buying a 1g legend cus i'm sure they go about as cheap as a 3gee anyways.

a b-series would open up more potential for mods in the future. like i mentioned, you would have suspension, fitment, and weight distribution problems with a v6... and you have to deal with 2 exhaust manifolds and a big transmission, not just the engine.

anyways, before we go off topic even more...how are the axles coming ray?

[racetek82]

I'm awaiting a set of used PRI axles from a forum member. When I get them I'll take measurements for the driver side axle and see if any stock honda axles will fit. If not I can try to contact TCI in regards to custom making these axles on a by order basis.

Also, after looking at the mounts again, I may be able to offer a full kit, but some welding and hammer swinging will be necessary to fit the tranny mount in. More info as it comes...

[Vanilla Sky]

hey man, as for a little "welding and hammer swinging", i honestly don't see anybody willing to swap a motor in is gonna care, as long as it's done right...
:thumbsup: for the work, man

[mouchyn]

i'm guessing that if PRI had to make axles, then no other stock honda ones worked well enough to be distributed. Then again, that could have been due to their design and engine placement. The engine being shifted just a few mm one way or another would totally change the axles required to work properly, right?

[carotman]

Awesome job dude.

Finally someone with welding skills that put them to a good use

I might even buy those.... just in case

[masterkillalw]

Yea man PLZ let me know when ur ready to ship a set of these bad boys...I have a 1987 Prelude and a B18A1 ready to go into it...all I need is the mounts and which axles to use...

[racetek82]

For those who have the PRI swap, what intermediate shaft did you use?

[SteveDX89]

For those who have the PRI swap, what intermediate shaft did you use?

The regular B intermediate shaft.

[88LXi68]

it actually depends on the tranny you are using...

[racetek82]

I think I need the B18A intermediate shaft, it has a female inlet. The B18B/C and B16 intermediates use a male outlet.

[SQ is the SQUAD]

i gotta get going, but i still gotta finda a freeking cheep b18a

[SteveDX89]

My B16 shaft was male on the tranny side, female on the axle side.

[mouchyn]

My B16 shaft was male on the tranny side, female on the axle side.

that's how they all are. how else could they be?

[SteveDX89]

Read racetek's post. He made it sound like his is different so I just clarified. Also, on other engine series, the intermediate shaft has a male outer end so I didn't know if the newer B's were like that as well.

[mouchyn]

so, the driver's side axle has a female and a male end? that's weird. i've never seen that before...

[SteveDX89]

The bottom one is an H22 intermediate shaft.

[mouchyn]

the h22 i installed had an intermediate shaft like the b20. strange.

[88LXi68]

on newer b-series engines the side that goes into the tranny is male and the side that goes to the axle is male. Mike in NYC had an intermediate shaft like that, so they are not all the same.
