if u have that kind of money, k20 turbo. if not, ls turbo.

im sure plenty will say ls/vtec turbo, but i honestly dont think its worth the money with a turbo

edit: reason i say not ls/vtec is cuz the money not spent on the vtec conversion can be put towards making boost safer/more reliable(and even more boost) on the LS

 

he is right.. i say ls/vtec turbo..

 

its obvious the k20 is more advanced and a better motor but for the price and ease your b-series will do just fine

 

ls turbo would give plenty of power, idk if makin a relaible ls/vtec with boost would be a good investment of funds. if u can afford a k20a2 it would be an awsome swap

 

just be warned, a k20 turbo would be a messy custom setup with lots of fabbing and trimming. you can have a hell of alot more power if you take that money, get a bare b18c1 bottom end, build it for boost, slap a head on it and boost the hell out of it.

 

don't listen to people that say ls vtec isn't reliable. k swap sounds yummy but if you don't got the deep pockets, just stick with the B series

 

my arguement isnt against the reliability of ls/vtec. its cost to power.

 

i considered going with a k swap for my build, but I stuck with the B series because there is so much aftermarket support for it

 

theres plenty of k-series aftermarket/turbo prodcts out there

 

^^ but lets take into account price...

a quality turbo manifold for a b-series in an integra chassis is about 300...

a quality turbo manifold for a k-series in an integra chassis is about 700+... ect ect for every other piece.

I agree with danny, the k-series is just to pricey for the integra. wait a few years and that might change

 

oh i kno its a lot more expensive, all im sayin is theres plenty you can do w/ a k-series integra

 

if you're loaded

k20 w/ turbo or not

if you're strapped

ls turbo

if you're strapped but love v-tec

ls/v-tec w/ turbo

i had a ls/v-tec and was not happy
i also had a b20/v-tec, i was very happy

k swap is going to cost you a lot because you have to have custom header, custom exhaust piping, custom this and custom that, if you can't find a jdm ecu you'll need to get a kpro ($1500) so be careful even if you can afford a k series engine

 

The reason K series parts are more expensive is often due to the fact that there are fewer parts avaliable. less competition means higher prices. List the companies that make turbo manfiolds for a B series motor, then list the same for the K series. one list is going to be longer.

B SERIES FTMFW!!!!!

i say stick with the LS and boost. have a BUILT LS TURBO!!!

k swap is becoming too comon,in a few years no ones gona have b-series in there integra or civic.

and Vtak...(i no its VTEC jp) dont do it ECU,wiring , head etc... u could have priced a kit together. so my vote goes to LS TURBOOOO

 

I say save your hard earn money, get the k20a and call it a day. first go n/a if you have more money then boost it if u want. This discussion has been covered many times and everyone know that k20a is the latest advance technology from honda, so it must be better. B series is so cliche, pple been there and done that. so you want to be typical or have a rare monster set up that will raped other common project.

 

why would u get a k series and then boost it? are you going for reliability, if so dont go ls vtec turbo, k20 + turbo is gonna cost you more than a leg and arm, i would boost a b20 tho. All you need is the motor, u can keep ls tranny, ls ecu and harness.

 

k24 turbo anyone? already lower compression and more displacement. there is no replacement for displacement. or what...?

the accord and crv k24 is just over 9.5:1 compression. just think of the torque!!!

 

b20 sleeves are known to crack. wouldnt go that route. stock ls block will be fine depending on your tune/power goals

 

b20 or ls, if you keep it b series u still have to build internals.

Not necessarily. All depends on power goals and tune

 

Plenty of info on all of these engines to make an educated decision.

Just saying "I have an integra, I want to go fast" isn't helping anybody. We don't know your goals, budget, powerband location, engine preference i.e. f/i or n/a. It's all guesswork and spoonfeeding.
