i have a 89 si with the dohc non vtec and i want to have vtec so what would be better the vtec zc or d16 and would it be faster ?

 

d15b vtec

 

Neither. The have just about the same set up so the better deal per $$$/mileage is the better way of going.

You feel more power out of a ZC/D16 than the D15B (which everyone is one some kick for). The D15B only really makes the correct power when mated up with the correct proper JDM D15B ECU -which most people just us a P28 which has different curves.

Get a d16z6 with your stock si tranny and convert to obd1 and run a p28..D16z6 is basically the same as a sohc vtec zc..And its cheaper and easy to find everywhere..

What motor do you have now? Im assuming dohc zc.?

i agree they are about the same...i would go with which ever one i could get cheaper

 

hee dident ask abowt d15b vtec..so wi r u gis talkin abowt it 4?

 

Between an OBD1 SOHC ZC VTEC motor and D16Z6, you probably want to go w/ the ZC since it'll have lower mileage than any Z6 you find laying around.

 

is it faster then the dohc zc?

 

just keep what you have unless it isn't running or something... neither of your choices will make much more power or have any more potential than what you've already got.

 

i just got a ls motor and im gonna make it ls/vtec

 

I would say if you're staying SOHC go with the VTEC, you'll get 25 extra HP.
