so i got this 91 prelude with a blown motor and a spare b18c motor just sitting around.. wondering if i can make it work.. does anyone make mounts/ wiring harness for the swap? I know it's a pretty unorthodox swap but just wondering if it would work..

Yemdogg

sorry.. just realized this is in the wrong thread.

Nobody makes any parts for this swap. It has been done a few (and i stress FEW) times but it was all custom. There is mounts and axles available for an H22 swap. If your car came with the 2.1 liter you are already OBD1 and the swap would be that much easier. If you decide to go that route then contact 1funryd. He sells the mounts for the swap.

I know that Hasport made B-series swap mounts at one point. I just checked their site and it appears that they don't anymore. I guess finding a used set or custom would be the way to do it. From what I remember, the B-series motors in civics/integras are a little taller than the B20/21 offered in the 3rd gen hence why they have fitment issues.

Other than that, I'd recommend 98ekb16's advice. Good luck.

1funryd

Correction my friend, Hasport never made anything for the 3rd gens EVER!!!.

I should know, they practically insulted me when I was trying to work with them to make the H22 swap, they basically threw out a number and told me all or none, not even being nice about it.

So, I went on my own and got it done with someone with better customer service(at the time) and now its done and I have them produced.

The only B(civic/integra) mounts ever made were totally custom, and they still are not mass producing them or even doing one offs yet. The fabricator is just too busy to remake them. He said eventually he will.

But since I already worked to get the H22/23 swap supported and those motors are much more powerful right out of the box, the demand for the B series mounts are just too low, so that is why I never got them produced.

There are more inquiries now, but still no real takers. And I am sorry but one off's are not a reality unless you put down some serious coin.

If you need info on that swap, contact Alex at Humble performance. He currently has one running, deep into the 11's with a b18 swap. www.humbleperformance.com

Hasport

correct we have never made anything for the 88-91 prelude. place racing made h22 kits back in the day

we also dont work with anyone to make mounts so no number would have ever been thrown out there

oh and fyi we have excellent customer service just because we dont make a particular product or not going to make a particular product does not equal bad customer service

1funryd

Sorry but I do not know who the person was in 2006 when I was trying to get some help from you guys and he who represented you guys did not represent your company in a very good light.

I was very cordial and polite, but he was arrogant and instulting. I tried a few times, but just because you guys were the big boys on the block does not give any of you the right to treat a potential customer like that.

So I still stand by what I said, that your customer service to a community of Prelude enthusiasts was very poor.

But I am not ignorant to the fact, that things change and maybe that person changed and learned something.

So there is always the present and the future.

that would be freaking sweet too see.....
i couldnt find anything on there website about a b18 11sec prelude
but i would love too see the pics of it

1funryd

I did not see anywhere where he did a B18 swap into a 3rd gen Prelude?

Sorry here is the direct links. Thought it was a 3rd gen, might be a second gen.

The motor is making more power now, if you are interested in it, contact humble directly and they will give you more info.

1funryd

Correct that is an 87Si 2.0(swapped now) 2nd gen lude. Not the 3rd gen 88-91.

i pretty sure the mounts, and principals are very similiar from 87-88 though.

1funryd

Again my friend that is totally incorrect.

The 87Si' had nothing in common with the 88-91 ludes.

The 3rd gen lude motors were cast at an 18 degree angle so as to sit in the engineless design engine bay.

This is what makes it difficult to do swaps for this chassis, its too hard to come up with a good sitting in the engine bay.

The H22/23 and Civic/Integra B series motors are tall by comparison.

Now like what was said earlier, there are a few and I stress a few steel fabricated mounts that put a GSR B18 motor and tranny in a 3rd gen, but there were issues like one lude had to keep replacing his axle once a year because it would break.
The other lude had a rear mount engine break due to the design of the rear mount, but he fixed it from the last time I heard.

But since then there was no real demand to put a smaller discplacement motor when I pushed to get the H motors in there and the mounts fabricated out of Billet Aluminuium.

I tried to push the B series swap, but one many realized that they got more torque and power out of the box with an H22, it just fizzled.

Now we have more inquiries but still not enough serious demand, so its possible they might get made, but only time will tell.

An H in an old school would be pretty bad ***, I'd almost buy an old school for the kicks of doing it.

damn Sean, you represent the 3g community everywhere. glad to see you here bud!

1funryd

Just trying to keep things honest and accurate so people do not get it all mixed up.

psychoboy

it's not impossible, but it's not a drop-in affair either.



i'm using DA axles, and i swapped DA hubs into my knuckles (since the 90-91 hubs are the big spline style).

all accessories fit with the stock crosses, but it's damn close.
the stock exhaust manifold should fit with the stock front cross (the big *** type R almost fits)

the tranny mount is no real trick, would be easy to make in the aftermarket.
the front mount doesn't exist on the hydro tranny, so there's a possible concern for some people.
the driver's DC mount gets into the inner structure. the DA mount goes way forward and wipes out the cruise and p/s reservoir. again, a solvable problem but a problem nonetheless.
none of the rear mounts work with the cross, they are all too low. couple of options to get around it, like the other two.

chassis is cable shift, tranny is rod shift. there's room between the steering rod and the exhaust to snake some rods, and the chassis already has a knockout in place for a shifter, so it's not impossible, it's just tricky.

the standard B doesn't lean like our B20A did, but it still fits under the hood without getting under the front to back cross....tho it's pretty tight.

as soon as i get my new DD, i'll be parting my 98 SE to give this car its drivetrain, the stuff in the pics is just place holder parts.

Andrew at Frontline Fabrications has done this swap as well and is in the works of offering a b-series swap kit for the BA chassis. Contact him for more details.

1funryd

Yes we know all about Andrew. He produced the kit for a member on pp.com who is now in the military and away from his 3rd gen.

That was the person I was speaking of who produced the kit and we are waiting on for him to go full on with production, but it is on the back burner for now.
