i want to know how to make my 91 prelude (non si) faster. someone help me. its completely stock in great condition.

 

lol. engine swap? turbo? nitrous? you need to research more man.

 

If it's not an Si, it's an S model. That means you have computer controlled carbs.

You should sell your S, and get an Si.

 

this is research. and what do you meen computer controlled carb. how do i stop that. and also. what b series head would fit on my (dont laugh) b21a1? and does that meen i got a 2.1 liter engine? any help would be appreciated. thanks

 

i had a 91 si years ago and i think it was 2.1

 

what would you recomend for upgrades? will a b16 or b18 head fit on a b21?

 

i think this question has been asked. From what i can remember, the b series that is in your 2.1 is a completly different block from say a CRV. I do not believe you can bolt any B series vtec head to it.

If you want to make it fast i suggest an H22A swap, with the ecu wiring and tranny, a full swap. But if you have your heart set on some weird hybrid setup, then go crvtec or something, whatever floats your boat.

 

easiest thing you can do on that car is drop a h23a1 block in it. though you will not get the performance of a vtec you will get a reasonable amount of HP out if it. h23a1 is also stock engine in a prelude so you could get out with minimal expense as compared to the h22 engine (h23 has no odb2 with no proactive computer controlling you can actually see alot of performance improvements from bolt ons) these are pretty common engines to pick up at salvage, average cost to rebuild is around 1500ish depending on how much milling is required ect.

 

4ws is technically not listed as an si

 

i can just drop an h22a into it? no problems? it will hook up to everything? i dont wanna buy a tranny. is that ok?

Is it a canadian model with the seat belts not attached to the doors? cuz the b21a1 is NOT carb'd it's fuel injected and it shoudl say PGM-FI on your intake manifold. and the b21a1 only comes on the 91 si there was no carbed preludes made in 1991 the s is the one with the 1.95 liter b20a5 yours is a 2.05 liter engine.

Well with the h23 or h22 you'll need custom mounts and a lot of other work there's only been a few succesful h22 swaps into the 3g lude and no h23 swaps that i know of into one.

Lots of problems and work and you will need a differnt tranny the stock one doesnt' work with any other honda engine.

A b18 head was once grafted onto a b21a1 or b20a5 block but the results weren't worth the amount of work or expense.

I'd recommend nitrous they got low compression (around 9:1) so they are good for nitrous or other f/i but nobody makes turbo manifolds for them anymore.

 

do a search.

3rd gen preludes are not good cadidates for swaps.

there is no easy way of boosting the power of the car, unfortunately.

 

My advice is to come over to http://www.preludepower.com and you'll find everything AND more than you'll ever want to know about the performance, possibilities, and trial and errors that have been documented about your car. I have a '90 Prelude Si 4WS turbo. If you don't want to check the site out, go with some quick advice. Go to http://www.nippon-motors.com, ask for a b20a (jdm 2.0) they are $650 shipped with everything you need to drop it in directly to your engine bay. No axles, vtec wiring, etc. needed. Then turbo that engine. It DOES respond very well to boost. Secret (which is no secret) is fuel management. That's it. Whatever more you need to know will be found a pp.com.

 

thank you so much. that sounds a little cheap for an entire engine that will actually not cost me an arm and a leg trying to get going after i buy it, then my car turns into a crazy money pit worse than that one movie. but if you say so.

also. is the b20 just like the rest of the b series engines, like they get 100 horsepower per liter?

and also. i went to the site. i didnt see it. do i have to ask specialy for it?
do you know the people that run it? can you get me a deal?

thanks

MmM not quite 100 hp/liter more like 100 wheel horse power. The b20a5/b20a3/b21a1 are not like ANY other b engine. They are bastards

 

LoL! Yes we do have the bastard engines. raoulduke, I was going to tell you that you do have to e-mail them a request, because of the low demand for them they don't have it up on their list, but they do always seem to have them available. I personally have not dealt with them, but the many ppl. I have talked to that have say that their cust. service is pretty good. I'd say e-mail them and just tell them what you want and be specific that you're looking for a B20a dohc out of a 88-91 prelude. Otherwise they might think you're wanting the CRV engine which you do not.

 

is there an easier way of making horsepower gains on the stock engine?
like exhaust or intake or cam gears. i heard that a better clutch will put more horsepower to the wheels. anything?

thanks.

 

an about that b20 swap. how would that be any better than the b21 that i hve. they are both non vtech. and both dohc. one is just smaller. i dont get it. is it because the b20 is JDM? does that make it magical?

 

*and

i meant "and", not "an"

 

use the 'edit' button next to the 'reply' button to correct grammer in your post or to add something, opposed to excessive posting

 

ok. now i am thouroughly confused. i was just at http://www.totaljdm.com/

they told me that i could get a b20 engine and put a b16 or b18 ls/vtech head on it. i thought that wasnt possible.

or is it the wrong b20?

someone please help!!!
i am new at this sort of thing.

thank you anyone

 

this is the actual quote

"Have you ever heard of the phrase "Frankenstien " in Hybrids? This is a great motor to buy if you are considering building a B20B with a B16A or B18C head. It offers great horsepower numbers verses torque. If you want the best of both worlds, torque and horsepower. This is one of the best motors to build. Being apart of the "B" serious family it will bolt in to most Honda's that have "Hybrid" possibilities. If you are a die hard racing fanatic or someone who just wants to be able to make a pass on the highway with confidents. This is a great motor to consider."

That site is talking about the b20b/z

We're talking about the b20a. Totally different.

 

THX red91sit, and sorry for any misinformation. for some reason i was thinking it was a 92 not a 91.

 

buy a new car more reliable and probly cheaper in the long run
