i am now working on another crx, an 85 dx. the plans for this is to have high fuel econ plus reliability so it can run a solo series. the car will not be an all out race car but duel purpose weekend racer.
Back to the situation; i found a b20 non-vtec and am thinking about doing the swap, any input on those who did this already. where any 1g ever produced with this motor (thinking on the basis the 1g optional F1-series steering wheel)

[E-AT_me]

no b series was ever available in a t-bar civic/crx.

Lol @ high fuel economy and "weekend racer"... You are all sorts of confused...

[Punjab]

my 86 si was getting in the ball park of 45-50mpg (..is that not high fuel economy) [its achievable dont kid me]
thanks for the bump by the way

back to the topic at hand:
so you know where im coming from,
From Wikipedia under Honda B engine;

"The B20A3 and B20A5 are the predecessor to the B family. All B-series engines were based from the B20A, but most engine components are not compatible. For more information, refer to the F1-series Honda race car that used a B20A engine. Also see Honda B20A engine."

knowing the crx had available a f1 steering wheel (as well as some other cars), i figured it would be only fitting to have a b20 as apposed to the standard ZC or swapped b16 in a race car

any info on the f1'ed crx options or car

anyway as for this project besides the excitement of a b20 (which, i know of one for super cheap and the only reason i brought this topic up) is when the time comes im thinking (as i have been for some time now) of doing a Honda C engine swap, as for which one.. the availability of everything will determine

cr-ns-x

I'm pretty sure the F1 CRX only got the steering wheel and a special paint scheme. All white, red trim line correct? I dunno, but as far as your B20 swap; it has been done. Screech has a CRV motor I'm pretty sure and he's running OBD2. Starting with a dx will be a bit more of a challenge; but can and has been done. Its just fuel tank and wiring harness. Good luck with your project, however if it were me, I would just do an Si drivetrain swap if you are looking for MPG's and some weekend fun.

Keep us posted whatever you decide.

The F1 was a very limited one year only special edition interior/exterior package for the jdm Si. White paint job/black trim, black interior, bronze tint glass, white 14" wheels, yellow foglights, F1 red/black stickers, rear spoiler and F1 seats/steering wheel. The catalog shows it also comes with the 1.6L 16 valve PGM-FI ZC.


There was also the F1 Civic hatch, F1 Integra and F1 Accord and possibly more as well.

the B-series that the wikipedia is mentioning is probably the oddball b-series mainly found in 3rd gen preludes

[Punjab]

jdm4drda7- i think you were the one who helped out when another member was pinned on some f1 questions

specialTEG - ya that is what i found; same b motor, same car

hmm i guessing its going to be tough finding info on the f1 b20,

Im thinking that they actually put a b20 in a crx also because of the crx 2.0 correct? Its on GT5. Maybe someone can shed light on the subject.

But if it was any B series motor it would have been the B series out of the SECOND GEN prelude not THIRD GEN. It was called a B20a3, PGMFI. It wasnt in USDM or CDN prelude but rather the JDM Preludes. This motor had 160 hp, a great start. But because i have never even heard of anyone swapping one into a crx, im not sure how it would work. Most people would compare the B20a3 to a H or F series motor due to the block design and mounts.

There would be so much work to install a B20a3 into it crx, that it may not be worth it. It may be a good idea to have a look on PRELUDEPOWER.COM for some answers on your B20a3. The B20a5 was used in the EDM Preludes. There is good talk about B20a3's with dual weber dcoe 50's making 220 whp after a port, cam ect. In my opinion, there is no real such thing as performance and fuel economy. Peppy and cheap on gas maybe. Anyways, if you want more Hp, cheapest way would be to do the teg swap, if you want more, do a REAL B series not the JDM Prelude one.

Oh and to comment on the third gen having a b20, i believe that the jdm one may have.

[zakats]

a fresh B16 or B18 with a transmission set up for fuel economy (hybrid with LS 5th or just an LS trans) can get decent fuel economy but it won't likely do 40+

[E-AT_me]

biggest issue with the lude motors is that they are tilted, not straight up and down like a "normal" b series engine...

and don't go by GT5 has one etc... the original Gran Turismo had a mid-engine del sol with 500hp.. i don't really see those running around anywhere, do you?

and i can tell you right now, the B20a that honda used in the "f1 car" is no where near that of a standard issue B20. also, it was definitely NOT in an F1 car, maybe an open wheeled race car in a formula class, but not F1.

Ok theres all sorts going on in this thread lol

First off F1 edition cars are factory JDM Si models ONLY 1986 of course so the facelift model. all I have seen were white in color Greek White NH-82 as some know the JDM Si models already had the DOHC 1600cc ZC browntop motor, so nothing special there. The F1 edition was really just a facelift visually in a couple of places inside and out but was only in limited production.

They have/had off the top of my head
F-1 special edition decals
red pinstriping down the side
white color coded door handles
white color coded wing mirror bodies
white color coded f1 special edition alloy wheels
F1 edition seats stitched with the F1 logo
F1 edition steering wheel center logo
F1 edition printed rear mudflaps (splash guards)
F1 edition checkered floor mat set

Anything else was either factory or factory optional on ALL Si models regardless of weather it was a F1 edition or not, This was more or less the same for all models Civic CRX Integra Accord, and possibly Prelude(I have not seen a F1 edition BA1 Prelude in person)

Now secondly

There is a B20A that sits upright its called a B20A(no sub code) not a B20A5 (those lean backwards in the 3rd gen lude) The B20A came in BA1 2.0SI Preludes 1985-1987 and the CA3 2.0Si Accord 1986 - 1989 and are JDM ONLY, the B20A motor did make it into EDM 85 - 87 preludes as a B20A1 and made less power than the JDM model of course.
Here's a quick picture.

This would be quite easy to convert into a 1G CRX / 3G Civic but they almost don't exist in the US or Canada ones that do have been imported and for the money you would be better off going with a VTEC B series

Also about the Mugen B20A it does exist and was used in F3 race cars in the 80s and early 90s the engine is called a MF204 go ahead google it there's a bit of information around about it.
Here is a couple of threads.

The money shot B20A, Might be hard to get ahold of one let alone figure out how to install it in a 1G CRX or 3G civic



And that concludes today's history lesson...

[kaymo]

im still trying to figure out why people are thinking the 1G CRX came with anything other than a 1.6L DOHC non-vtec. its like the CRX wiki that claimed there was a Type R version of the 87 CRX that had a b16 and had gold trim and lettering.
