What is the big benifit of changing heads and putting them on different motors?
is the heads more important

 

That is a pretty open ended question! The are many different heads for different series of engines, both vtec and non

Most commonly, people swap vtec heads onto non vtec blocks, because they are higher flow making more power. Added wiring, oil lines and changing your ecu would also be needed

 

the big difference used to be saving money. now people found that unreliable so cost has gone up for the sake of reliability. the big difference now is a block with more displacement. but thats just what I think

 

There are exceptions to this.......

My last car was a 96 Civic Hatch with CRV B20Z engine. I bought a different head for it for higher flow. Called a P8R, it has oem 33mm oversize valve, same as dohc vtec heads, and also had the same flow as a vtec head, without any other modifications!

 

thanks
what do yall think a b20z block with a gsr head will produce... hp? torque?

 

I saw one with ctr cams and a tune put down 190 @wheels.
Stock other then that, of corse had rod bolts/head studs

 

ok cool

 

damn thts pretty good

 

My thoughts exactly. Was a quick little car.
its now on the path to fully built, vtec killers and itbs, should be even more fun

 

mmmmmm mmmmmmmmmmmm gotta love some vtec killers

 

im dropping it in a civic or integra

PS: is obd1 harness for integra and civics the same?
