I am building a single v turbo and would like to know if anyone has any info on which motor to use versus the other

 

im not familiar with the y5, im guessing thats non-vtec, but everyone i know with a sohc vtec turbo setup is running 12-13s, sooo the z6 is a greaaaaat motor to boost and the parts are plentiful.

 

the y5 is vtec i believe anybody know some where that i can find out

 

Yea its Vtec-E (pretty much the same I'm guessing?)

 

i kno a kid with an HX, kit, rims, full catback, h/i, i tore his *** up with my crx dx, intake, thats it..... go with the Z6

 

all about the vtec-e: http://www.leecao.com/honda/vtec/sohcvtece.html
basically what vtec-e does: it just opens the second valve at like 2500 rpm-it does this by pinning a dead valve to the working valve at that certain rpm, thus opening one more valve per cylinder. It does this so that the air fuel misxture is not lean at low rpm's. This motor can make the civic HX launch off the line good, but after that, its only 115 hp.(the d16z6 is only 125 hp) and remember, the vtec-e motor is for ecomony purposes only, not performance. But it would be sweet to use the d16y5 motor and boost it and still get like over 38 MPG on the highway, and be able to smoke a lot of other cars getting like under 20 MPG. i would think the vtec-e would like boost, since the whole purpose of it is getting the right air, fuel mixture, and with boost, it would be able to control the boost at low rpm's. even know you will be above 2500 like almost all of the time. but i would still like to win races and laugh at them when they are fillinf up for gas right away. remember, the other motor has like only 10 more HP to it, which if you put a header and inake on the vtec-e, your in the same spot as the factory d16z6. and remember, you probably can get the vtec-e motor for A LOT less! and we all know everyone wants the best bang for the buck.

OOO nooooo. VTEC-E is very different. Principals are the same, implementation is different. One's for performance... one's for economy. That's what the E is for.

and remember one other thing, POWER TO WEIGHT ratio is a huge thing also. dude, you would of ripped on the same car with a d16z6, which is only 10 more hp, your crx if just a HELL of a lot lighter. I had a eg hatch, and i have the vtec-e motor in it at first, and i could waste a newer coupe with the same motor. weight is a HUGE factor!!!! its like saying my 50 HP kart can kick the **** out of your crx, its all about weight. Why do you think heavy mustangs and older cars need such big motor to go as fast as hondas? and why does a accord need a bigger motor than a civic? ITS A ABOUT WEIGHT.

 

Boosted HX's are pretty nice. Due to the fact that they dont have shift points or anything. So you wont get Turbo lag like you would with a Manual Car. its non stop boost. (correct me if im wrong though)

What are you talking about? Are you saying all HX's are automatic?? And turbo lag is called that becasue it take a while for the turbo to spool up and boost at its maximum That is why ball bearing turbo'sare sweet- they spool up faster. Any car with a turbo will have lag. automotic or manual. so im not sure what you are trying to get at.
I have even read a guy running 2 turbos, one small one, and one big one, the small one will spool so fast, meaing mo lag, and at higher rpm, the bigger turbo will be spooled up and taking over the job of boosting the motor.

That's called sequntial twin turbos. Most people with cars that came with those stock ditch them for a single turbo.

extally. talking about this turbo set up explains what turbo lag is a little more., and you nailed the technical term perfectly. today turbos are much more advaced and you can buy a awesom turbo that hardly lags at all. Hope that all helps.
