engine swap questions

[wannabe racer]

I have yet to buy my first car and was considering a CRX and dropping the b16a in there.  How much did this cost any of you who have done it?

I read elsewhere that putting a turbo on a b16a engine was stupid because of its high compression and revs.  is what I've read based in fact?  I was wondering, because, I hope to eventually get a turbo for my car.  I still have a lot to learn about modding cars, and I hope that this forum can help me.  Thanks for any advice.

expect around 2000-3500 for the whole engine tranny and computer swapped into your car (including the motor mounts, and all the other junk needed)

closer to 2g's if you drop it in ghetto style and dont change anything, closer to 3500 if you change a lot of the worn parts, clutch, belts and gaskets, and install it cleanly (or have it installed cleanly)


a b16 isnt the ideal motor to turbo, but theres nothing wrong with adding a turbo to it. if you want to run a lot of boost on the turbo, you would probably want to lower the compression in the cumbustion chamber (with lower compression pistons) because it will cause less stress on the motor that way, and you would also want to change the rod bolts, or perhaps the rods as well. (if you want more boost that is..)



if you do plan on going with a turbo, you might want to consider swapping a b18a/b into the motor (the engine from a 90-96 integra LS) because the motor comes with a fairly low compression ratio, it is a very stong motor which can handle boost well, and the gearing of the transmissions would be a little more ideal for turbo applications.

the car would be a little slower initially with a b18, but it has more torque which is nicer for daily driving, and it will handle the boost nicely which means you could turn it up some, and with some internal modifications (as well as fuel and exhaust mods) you could really turn up the boost!!

a b18a/b swap is almost identical to a b16 swap, so the prices would be the same as well....

how much does a b18 weigh over a b16?

[masta shark]

i think the ls motor and the b16 motor would be withing 15 lbs of each other....

a gsr motor (b18C1) is going to weigh like 25-35 lbs more than a b16, but a gsr motor is much larger than an ls motor

[Venom TypeR]

what are the specs for an ls?

And are the b18s non-vtec?

Check out page 177 of the September Sport Compact Car.  It shows an H22 next to a D15.  

And people think I'm crazy to say that the H22 in a car meant to have a D series would adversly affect handling.  Well, they're dumb-asses, not me.

And yeah, I know this didn't really add any relivant info to the post.  Wait, I don't care !

[Venom TypeR]

oh yeah, and whats up with b20s?

[Evil CRX]

ok the specs on the b18a/b is about 140 hp and 116 ft/lbs. of torque.  I could be wrong on the torque.  The b18a/b is a non vtec motor but you can always put the b16 heads on it but that would most likely be pointless.  And the deal with the b20's is it's a CRV motor with a GS-R head on it.  You would need to do a hydro tranny swap to get everything to work right because the prefered tranny for that set up is the type r.  I hope I helped you out a little bit.  Oh and the torque for the b20 is up arround 140 or better.

[Venom TypeR]

ok, thanks.

Is it very practical to do the b20 deal?  Is it expensive?

What would putting a stroker kit on a b16 do to the compression?  Is going turbo with a stroker kit alright?  Would it be very powerful for the price?

[DamonK]

the b20vtec is slightly more complicated than an ls/vtec due to insufficient valve pockets on the stock pistons for the vtec head but basically fitting the head to the block is no different than an ls/vtec.  if you are going to go frankenstein, i would do the b20vtec.  210 hp (and 160 lb-ft) at the wheels is entirely reasonable with endyn pistons(11.5-12.0:1) and r type cams.  some even make 235 hp at the wheels (at 9600 rpm!).  the rod/stroke ratio isn't as good as a b16a, however, so it isn't as revvable.  with aftermarket pistons and rods and the stock valvetrain i wouldn't take it past 7500, maybe 8000 just to be safe.  yes it is expensive, however.  it would be reliable and fast as #### in crx, though.  stroker kits are very expensive and not really worth the money.  you'd save money buying a gsr motor to begin with.

[Venom TypeR]

alright

how much does a b20 swap cost usually?

[dvscrx]

does the b20 have oil squirters??or is it prety much the same as the ls motor?

[DamonK]

Here are the parts you need for a great setup..

and there you have it....a setup with mostly all Honda parts...total bill for that: about...񙾞  

I got that from importreview.com.  You really could probably do it for less, but that's what a totally built frankenstein costs.  it kind of nickel and dimes you.

I'll just stick to my B16 swap........ much simpler :) Change internals, add turbo, run 11's drive home. That's fast enough for me :)
