Hey h-t I have a b20 on boost so my friend is goin to buy it from me so I plan on getting a new motor but I want a little peppy and good mpg owl was thinking of getting one of those motors wich one do u recommend its a 97 civic ex I maybe boosting the single gingle is a few months

 

Which D15b?

 

The reg d15b vtec I was think the 3 stage but u whould have deal with wiring and ecu and whould the vtec be just as loud as the y8

 

you want to know which motor would hit vtec louder? Im not sure why...but Id guess it'd be similar db's, lol
the stage 3 vtec wasn't made to be a fast motor, its designed to get good gas mpg.

 

Yea I was gona get the three stage but the ecu pr

 

Ecu prob so I was think the reg d15b vtec so whould the be a good motor to do and I plan on prob going boost later but for now I'm looking for fun with good mpg

 

if your running a b20...Id sell it, and replace with a b18....they're cheap, and if you want boost again, its easy, cheap and nice gains.

 

Well the guy is buy my whole swap and the main reason I said yes is cuz I don't want to dump more money in to it for now so ill rather just run a single cam and save money for now

 

HAHAHAHAHA........this thread is a lost cause.

 

Lmao I just wana no lol

 

Bump

 

i have a Y8 in my DD stock exhuaset on it but just to say i CANT hear the vtec activate at all so if you want to able to hear it kick in stick with a b series. but i love the milage i get on my y8 over my b18c5 still good power for DD but kinda suks if you have to pass on a single lane highway. (mines auto so that may be a part of it, but i have to back off and floor it to build speed before i pass)

if i was ever doing a swap i would probably choose a B series again over another D. much more fun in MY OPPINION

plus just a thought i havent ever read about tuning the 3 stage vtec is there anyone in your area tha can before you buy something you cant have tuned.

 

Yea true I have a b20b turbo gsr trans but I'm selling the swap and wana get a single cam to save money s for my next project in just stuck between the two motors d16 d15

 

just get the d16... the d15 has always been a big headache swap to get to run correctly as they had EGR valves and a ecu that only was avalible in japan. the 3 stage Vtec is made for gas mileage as it has a smaller vtec lobe for midrage power that kicks in at 3k and a Big vtec lobe for over 5k. You will never find a aftermarket Cam for that head and you will be stuck with your stock cam. its nice the d15 has a roller style valvetrain. if u wanna swap it in to save gas money then have fun. if ur planning on boosting the motor then just get a d16... a Z6 or A6 perferably
