Why would you do this and its a daily driven car so I wouldn't be boosten it pretty hard just on track day.....give me reasons why you would do an ls/vtec swap thanks for the help

Yeah thanks for the help but check this out....I got a d16a6 bottom end from a friend and we all know what car this motor cam from well we compared my d16y8 block to the a6 and the a6 doesn't have a crank positioning sensor and some other sensors on the back so I didn't even wanna figure out how to make the a6 block work in my car we thought it would throw codes all day and run like a terd....wouldn't this be the same effect if we ran a obd1 bottom end in a obd2 car....I did a post in clubcivic about hooking the a6 up in my car and no one on their could give me any help I guess you don't see many a6 blocks going in a 99 ex coupe. Let me know thanks

I wouldn't do an LS/vtec unless i was to build the block, which gets expensive. You can make good power on a boosted LS, because you can run a little higher boost on the LS with it's lower compression and run into fewer problems on pump gas without having to worry as much about reliability. A boosted LS is also going to put down much better torque than the b16 (it's a big difference going from the 1.6 block to the 1.8), so it's a little more fun to drive on the street. But mainly it would be cheaper and still put down what you're looking for without building the motor.

But I am going to build the motor and I will be running a vtec head if I ran this setup thats why I post such a long post for my first one so I wouldn't have to explain anything I put on their exactly what I was looking to....the block will be built it will be a vtec head I am doing it right the first time cause its daily driven and I don't want to pull the block out again unless something happens but I want the extra security that I know I at least built the block and not running stock internals. If I can build a motor to support 500hp and I run a safe 300whp then I am happy its not a drag queen it will be a reliable every day driver. Thanks for giving advice between a 1.6 and a 1.8 I def. would like the extra torque for stop and go driving since hondas need all the torque then can get.

Dude. Why even waste your money on a motor swap. When you could just build the motor you have now and throw the boost too it. Your d16y8 has potential. With a few internal reinforcements, the right kind of turbo and manifold setup and a good fuel mangement tuning you can easily obtain 250-300hp daily.

Check out this dudes setup..

286hp and 218ft/lbs of torque. Not bad for a SOHC.
I found that as a quick reference, but I have read of a few people putting down 400+hp out of a d-series.


But if you are set on putting a B-series in I would suggest going with a B18C or B18B.. Sure the B16 is fine, but your torque numbers are still going to be lower than compared to a turbo B18. Plus you could get just as much torque or sometimes more out of a turbo D16.

Good luck...

Thats not if an option the y8 doesn't flow as good as a b-series vtec head plus you have a lot more timing options with a dual cam. Not to mention the d-series rods are weak, not to mention it has small bore at only 75mm were as a stock b-series as 81mm bore size and if you bore the d-series over stock the walls are more flexible, not saying a d-series is bad cause they can hit 10sec 1/4 miles but I want the b-series with the better timing options and the better strength and flow. Thats why I didn't even want to mess with my d16y8. Not to mention I can get a b18b for like $800 for the whole swap. 1.8 equals more torque which Honda's need and a d16y8 has no torque

Tetronious.....I live near Harrisonburg to what car do you drive maybe I have seen it?

If you are going to build it fully, everything you mentioned there pretty much doesn't matter. Sleeves + aftermarket rods take care of the weak bottom end, and a good port/polish and valve job take care of the flow.

Anyways, since you are planning on spending a good deal of money on it, just get the LS longblock, sell the head, sleeve the bottom end/stroke it out to a 2.0L, and throw a VTEC head on it. I wouldn't even worry about doing anything to the head other than cam gears + cams because honestly you would be wasting some extra money if you're only shooting for the ~300-350whp range.

Ah yes, a b18b is a good and efficent block for boost. Your right on the b-series advantages. A much better starting point compared to a d.
