OK guys and gals i got an 89 prelude and i wanna have some fun with it but i dont wanna break the bank....i want to make the B20 motor v-tech.....what im lookin for is how to do that.....im also not sure on what head will fit what motor.....i was wondering if a b16 or b18 head would fit on it....also if ne one else knows any other things i need to do to the motor to make it v-tech let me know....THANS VERY MUCH

 

Never heard of a B20 Vtec.......Might just cost you as much for an H22

 

no...what i want to do is make a B20 which is not V-tech into V-tech.....the reason i want to is because H22 is super expensive and i think for a head and an ECU will be cheaper i just need to know what parts

 

you need a b20 block.. and a b16 head.. to make a b20 vtec.. i am sure you have to change some of the gears to match up for the vtec timing belt. but other than that it bolts right up.. i had a friend drop one in his civic..

 

hey thanks...and what do u mean by gears...like in the transmission or like pullys and shit on the motor it self....well thanks

 

You'll also need one of these to make it V-tech-->

 

you need to change the timing gears just for the cams... i am not sure. you have to see if the teeth match up if they do.. then you dont have to change them. but if not... it is just the inner most gear on the crank.. and you will need a new ecu... for the vtec... but other than that.. it was a rather simple swap..

 

ok hey thanks man uve been lots of help...umm u know of ne where that i could get just a head?.....and an ecu cause ive looked oon ebay and there way expensive cause there all ported and polished already and there asking like 1500 for the head

 

your probably wanting to make the stock motor out of your prelude vtec right? well the B20 vtec motors your hearing about is a B20 out of a crv with a b16 head, or gsr head if you wanted. the motors are a little different. im not too sure what the difference is, just thought id let you know you might not get what you expect out of it. and if your going to do that, you should probably get a b16 tranny too. just my opinion.

 

o and its "vtec" not v-tech. are you driving a phone, like above.
