want to swap motor for a better but dont know wat to go wit?

search

yes, search a little more

is it a si?

yeah its an si but wats the best motor i can get in it?

Do a search for the d16a1. That will drop right in. But the b-series motors can fit with heavy modifications. And welcome to the forums. :)

is there another motor thats better than the b16a1 that i can fit in it?

yes but they all take major mods to the firewall and motor mounts which if you put a b16a1 in it your going to have to modify the motor mounts anyways you can put a h22 in it bit you have to modify the firewall and motor mounts and if you really want to get tricky you can put a v-8 in it but that would be a lot of costom work i would recomend a d16a1 because its a very reliable swap that is very reliable and a simple self expanitory

i have a 86 civic si with a stock d16a1 and i stomp all over my buddies 95 integra with mods the d16a1 is not that bad of a engine and its not that hard finding mods for it

i would recomend a LS vtec if you really want to spend the money if not i think a b16 would be the way to go

about how much would the ls vtec cost? and which b16 series would be best?

The B18A with VTEC head (LS/VTEC) will cost anywhere from $2,000 to $10,000 depeding on how much reliability you want, cost of parts, and how fast you want to go. Same for the B16.

Expect to pay around $1,800 just for the parts needed to swap a B-series into your car, not including the cost of the motor and tranny.

An H22/23 is even faster but this is a full custom installation. Absolutely everything will have to be fabricated from scratch.

I'd go with the B16 because these cars don't need the extra torque of the B18 (with too much torque you'll just sit at the line spinning your tires while you watch your buddy's tail lights get smaller). Also a B16 can be purchased as a complete motor while the LS/VTEC is something you have to build. But if you have fat pockets go with a B18C.

BTW, a DOHC ZC or a D16A1 with ZC cams will be able to keep up with a B16. The Integra DOHC ZC or D16A1 doesn't require custom mounts, just buy a cheap '86-'89 Integra parts car and swap everything over including the disk brakes.

i have a 86 crx si and i want to put a b16a1 (jap-spec) motor in it with a vortech supercharger. I know that i need to get a complete conversion kit from the acura integra, but what all do i need from the integra. And i also know that i am going to need new motor mounts and all. if anyone has done a swap like this please let me know what all im gonna need to complete my swap.

i can get a b16a2 motor installed and all that for 6,000 dollars is that a good deal?

Including the motor, tranny, labor and warranty, it's a fair price...


But you're a fool to pay it.



If you do it yourself, it would cost up to $4,000 even if you paid top dollar for your parts. I'm certain you can do this swap yourself for under $3,000 if you do some research and aren't afraid of a wiring diagram and some fabrication.

BTW, here's a new company producing B-series mounts:

To elaborate on my first statement, you're a fool to pay $6,000 for a motor swap into an 84-'87 Civic/CRX. Most people (me included) would rather buy a nice Prelude, AWD DSM, Supra, RX7, MR2 Turbo, or 300ZX TT for the same price. It's just dumb to invest that much money into a 1G/3G. Keep in mind that if you spend $6,000 on a motor swap, you will never get that money back out of the car in a sale. You'd be lucky to get $3,000 for the complete car if you can find the one person in the world that is crazy enough to pay that much for a 1G/3G. Through my experience I found that if someone was going to pay more than $2,000 for a Civic, they'd rather buy an 88+.

I agree. The chassis is way to old to handle any serious power. Get a newer car then work on it.

i found another place where they will do it for 4,400 for a b16a2 and 5,200 for a b18c

which should i go with?

Neither.. you should start paying attention to the fact that you're going to be spinning your tires all over the place.. and realize what you're trying to do.. this is not a good thing for you to take on if you're not familiar with small lightwieght front wheel drive cars.. you should just take it in stride, keep the car streetable, and put a D16 teg motor in it... no money, except the price of the donor car, and a lil work, you can do the entire swap in less than 4 days, and that includes the disc brake conversion, etc.

it seems to me that the only reason you're interested in doing this swap is so that you can beat your friend's teg... foolish reasoning, if you ask me, but you didn't.

If you take into account the fact that his teg is heavier than your CRX, and your D16 with light mods will easily max out your useful power to weight ratio, you'll realise that you'll be WALKING HIM down the 1/4 mile with no troubles at all... and I'd imagine w/o using full throttle most times.

basically, your car fully equipped never weighed in more than 1800-1900 lbs... so about 180-190 HP would give you a 10:1 power to weight... which is borderline unsafe for a newb on the street... especially if you're not familiar with the car. You should be looking for more something like 160HP and not alot of bottom end... you wanna get the car moving before you start getting into your power band... so you need top-end power... turbo a rebuilt teg motor, you can easily get 160hp that will service your needs, and still get decent gas mileage, and cost A HELL OF ALOT LESS than a B series swap.
