i tried asking this in the hybrid forum but didnt get much of a response. so here goes...

what sort of engine swap options do i have for a 91 2.0 si? i'd rather not put a b20a5 back in... from a guide i saw, it basically said that the only engines worth putting in are a f22, h22 or h23 which would all require a mounting kit. how hard would it be to swap one of those three engines in? this would be my first swap so i wanna keep it relatively simple. also is it at all feasible to swap in any other engines like a b or d series (besides a replacement b20a5)?

also, where can i find mounting kits for a f or h engine? finally can i use my old tranny with any engine other than the b20a5 that came with my car? thx in advance for any help.

 

do a search in the prelude forum.

3rd gens are not swap friendly. you cannot use the current tranny with any engine other than the B20A. I recommend you get a JDM B20A, it's got the same power as a B21A1, minus the oil burning. It's also got higher compression (requires premium), but it's a good engine.

H series will ruin the balance of the car, unless you make the swap complicated (because the stock engine in 3rd gens sits tilted forward...). An F22 isn't worth it.

not good news, but that's how the cookie crumbles. if you really want power out of a 3rd gen, you need turbo on a B20A engine.

 

If you want an H-series engine in it, you'll have to make custom mounts.

 

thx for the info kablamo

i kinda figured it wasnt going to be a very swap friendly car. i'm not really looking so much to get power out of the car... as i am to just get it running just for the purpose of learning how to do an engine swap. i might just junk the car and look for a cheap civic or later gen lude that i can work on. hopefully i can find a 5th gen with an *** ton of miles on it, pull the engine and just make it into a project car.

as for the oil burning on the b20a5... i definitly can attest to that! i got the car at 170k and it burned oil the entire time i had it it was pretty bad just before the 3rd cylinder croaked. i coulda sworn it burned just as much oil as gas. i think it was mainly the 3rd cylinder that burned all the oil. my mechanic said the whole cylinder was like caked up with oil and ****, but i think the other 3 cylinders were fine.

thx again.

 

no problem!

sadly 3rd gens aren't tuner friendly cars... very nice cars, but they just don't fit into the current trends.

if you want a good swap, that would create a real beast, i'd recommend putting a B18C1 or B18C5 in an EF civic hatch good project car... not too complicated, but not a straight swap either.

as you can see from my sig, you're not the only one in the market for a 5th gen Prelude

 

yea i love the 5th gens... if my mom didnt buy herself a new bmw 330 and give me her 01 celica... i was definitly going to get a 5th gen.

i'm definitely considerin getting a civic (tho i'd prolly go with the newer body style if i do) and throwing either a b16 or b18 in it. that would probably be an even easier swap (into a newer civic body) since there should be less electrical stuff to worry about right?

 

as far as i know yes, as long as you are buying a VTEC chassis, it's fine.

if you can get the wiring harnesses from a parts car or from ebay, you'd be pretty much set though.

the older civics do have that sleeper appeal though...plus since i saw an episode of Best Motoring with a 1990 civic h/b with a stock ITR engine in it, it's definitely a swap i'd recommend!!

 

i think i know what civc hb your talking about actually lol. thats the civic from roaring vtec, the battle at 10k right?

yeah!! volume 4!

 

I just joined this forum in an effort to find some info about my old ride. She is an 88 Prelude Si w/a bunch of work done to the motor&suspension (cams, PP'd, valve job, headers, big TB, raised compression). She was beautiful in her day, but has been sitting for years.

I've checked into a rebuild for the motor, but it doesn't seem to be worth it. I found this site because I was loooking for swap info.

Can someone tell me (or point me in the right direction) what would be involved (effort& approx price) in putting a vtec motor into the car. Would it require a new tranny?

I had been thinking about an H series, but the above posts don't seem to agree.

TIA

the third gen is tuner friendly and a lot more easy than swaping an h motor in a civic! if you need any help or info pm me and i will give you any info regarding swaping for your 88-91 lude it is a fun swap and very worth it .just think the cars
weight is 2600 pounds not bad huh + 200hp=mad fun!
i have done two h swaps already on third gens and know of others like me who you can check out online, afterburners is going turbo runing uberdata on his third gen ,dont ever get a civic if you are in dought and just be like the mass of others!

 

you could just get ahold of me too... or join preludepower.com.... afterburners is running h22a and is boosted... his car is sweet looking although, im not to much of a fan on his exterior mods... the 3rd gen prelude seems like it was made mostly for handling.. it handles really well, 2ws or 4ws.. plus the 3rd gen 4ws was mechanical.. mechanical 4 wheel steering is known to not have many problems.. 3000gts were the same way... very well functional systems.. there are some 4th gens with 4ws but they had alot of problems mainly cuz of being electronic... but when it come to the motor.. id run a b20a with a b21 head( higher lifts) and intake manifold... the exhaust manifold on the b21 only has one 02 while the b20 has 2...

 

Thanks for the replies. I don't think I can PM on this board since I'm a new member.

I joined preludepower as well. I'm trying to get info right now. The car has been sitting for a few years and I'd like to do this on the side and keep costs down.

I love the car and had so much fun w/her while she was my main car. I hate to see it sitting there and don't want to junk it.

Can you give me some basics?

uhh i hope you're kidding... unless you are Ok with ruining the handling of the car, an H22 swap is NOT easy, certainly no more than in a civic.

i've explained this dozens of times before, do a search if you want.

 

why would you say this? the swap is done on (my) car , i done it on my own and the weight of the car has lowered since the swap, due to no ac ,so unless you have done it and have problems with it, do not say other wise.thanks. im not trying to be a *** but am sick of people talking about somthing they have not done.
the weight is distributed nicely, carbon hood battery in trunk the engine sits lower to clear the hoodline. the cars handiling is better than before

 

so keda,is your plan to go h22 is that what you need help with?
if so i can help

 

Right now, I am trying to explore my options. I'm not even sure where to begin with this, but boards are usually a good place to start.

The only swap I would be interested in is a vtec. I went to some local shop to enquire about a rebuild, but was quoted 3k+. As much as I love the car, it has been sitting for a long while.

What parts would I need and how much are they? Wiring harness? Tranny? Motor mounts?

Is an OBDII&gt;ODBI possible on Hondas?

Its been a long time since I've done anything in the Honda world. I embarrassed to say that I'm pretty out of touch with that is going on tuning wise. I even had to look up the engine numbers, which I used to know by heart.

 

i have a b21a1 it burns oil like mad what is wrong and what should i do,
should i worry?

 

2 of my friends have done it - 1 said it ruined the handling of the car, the other did it with a special (expensive) custom mount kit he got from a company in montreal to move the engine back compared to where it normally sits... handling was good, but not great.

if you dont intend on taking the car to road courses or autox's you may be ok, but for those uses a turbo may be better ( )

which carbon fiber hood did you get? there aren't many available for 3rd gens...at least not the last time i checked

swap in a jdm B20A

 

I am considering this swap, but I don't want the handling to suffer.

There will be no A/C, I can try to position the engine favorably, I'll custom make my own CF hood if I need to, and I'll be investing in suspension and chassis rigidity / LSD and other traction-related items.

Kablamo - Do you still think this swap would adversely affect the handling, even with those precautions? I like how my car handles now...

I have some audio stuff in the mid/rear of my car to balance the weight

Thanks...
