Hey I just bought an 89 Crx Si, Its got pretty high miles , but it runs great..

Im strongly considering doing a swap.. If anyone can please help me what the best type of engine to swap that would be great. Im strictly loooking for performance. I was thinking a B16 b18 or even the Zc Vtec engine. IF anyone can let me know what engine would work for the best performance.

Thanx

 

no such thing as zc vtec
get a zc dohc
should drop right in
get an extra 40 horses

Yes there is a vtec zc...

stock d16a6 motors make 106hp at flywheel and Stock dohc zc make 130 flywheel.
So how do u get 40hp increase..
And yes ZC's are complete bolt-in..and since u have an si no wiring is required..

Just search!! You'll find about a thousand more posts on this same topic. Most of which are noobs, like you, asking the same question, and gettin told to search just like u. Among them, there's some good info. Search = y0 friend

 

yea there is a zc vtec, its basically a d16z6 but JDM wit 140hp

you want performance, do any b series

 

Moron. There's the sohc vtec, and the dohc non-vtec. I think there's a third too.

 

where are all these hp #s coming from. I've never seen so much false info....

a dohc zc is 130hp which is 22 more than a d16a6 which is 108hp. There is a zc vtec in jdm land (same as a d16z6)but it is not 140hp!!! It's the same as the us motor which is 125hp.

Man, where do people get their information??

anyways....there are many choices for a swap, the question is, how much you wanna spend? B series is a better platform to start with no matter what but costs more money.

Personally, I am more than happy with a 96 LS motor in my 88 HF, but what else can you ask for in a 1900lb car?

 

B16A or B18C are your best choices i think

 

Everyone will tell you- "It all matters on how much you want to spend" first of all figure out your price range, and in the mean time here are some options you can start thinking about. Some of my info might not be perfect but its a start....

Cheapest of cheap: you could go with a sohc zc non vtec for around $400. simple as it gets just drop it in. I think its around 120 hp. Right next to this is the dohc zc, its about 100 or more bucks and gives you about 130hp.

Cheap: If you want vtec you could get a D16z6, but your also gonna have to get a vtec controller. as they said its 124hp.

After the D series go B series.

The B series have more power but cost more. To do these swaps you need new engine mounts which are around 300$ and I think new axles $200 plus the tranny and ECU etc. They can run more than 3000 total.

First there is the B18 which is from the Integras.

You can either go vtec or with out. There are different models ranging from 130hp to 190hp. of course more money for more power.

Next, youve got your popular B16 swap which is from the civics. These engines run usually a little more than $1000, but start with 160hp.

Then is the B20 from the CR-V.

Although this engine has less hp- 127 it has 133 lb torqe.

Even more there is the H series.

These are the more rare of swaps, The H series come from the Prelude. There is a lot more modifications required for this. These have anywhere from 160-220hp.

Last there is the K series. This comes from the RSX.

This is probably the most rare swap, but soon to become more popular as the engines become more plentiful. Making 160hp, but also with more torque.


Now a popular modification is to use forced induction later on.
using a turbo or a super charger. This runs from anywhere from $700-$3000.

The D series (ZC is a D series) can be boosted a little bit with out too much trouble.

The B16 Already has a high compression ratio, and its recomend to rebuild internals if you want to boost.

The B18 is pretty much the same except for the lower end ones like the non Vtec LS has a 9.2 compression ratio and can be boosted pretty well.

The B20 series can be boosted but its recomend to rebuild the internals as well, due to lower quality forged sleaves.

The H and the K series, I havent seen any of these boosted in a crx, but it would be cool. The H series I belives needs internal work, and the K can be boosted with good fuel management.

I Currently Have an 88 CRX DX. I dont make a lot of money so im going the cheap route. Dohc ZC eventually boosted.

Hope this helps you out. And again Im not sure if my info is perfect but I think its all around par.

PS wonder if this thread would work for a FAQ?

Newbie here. Will a d16z6 drop into an '89 CRX SI without requiring a new harness, CPU, mounts and axles? Thanks very much.

 

nope.

you need to get your stock mounts, need to convert to obd1, need a p28 ecu, and your stock axles will fit any d series trans.

 

thanks learned alot EF8 OWNS U..

 

The best bang for your buck would be a b16 from hmotorsonline. They range on price depending on generation. You can get a JDM B16a complete swap(motor,trans,ecu,etc) for 2 grand. You wont notice much of a torque gain but once vtec kicks in you will feel that extra surge of power compared to your current engine. Or you could get an h22 for the same price, but these require shaving the bay(in most cases I know) and a little more fabrication work to get it to fit correctly but is a beast stock motor in a Crx, but only issue with this is the H tranny has tall gears, so slower acceleration, but you also have a choice of going H2B.
