D16Y7 Boosted vs. B18C1
 

This might be a stupid question, but what engine would get more power, aD16Y7 with I/H/E with a surpercharger/turbo or a B18C1 with I/H/E only? Thanks foryour answers.

Can't put a header on a turbo engine. ;)

It depends on the boost and type of turbo you put on the y7. There is no way to really give you an answer to the question without taking into account the size of the turbo and the amount of boost it's running at. Considering the y7 wasn't built for high amounts of boost (7-10 psi on the stock bottom end with excellent tuning is about all you'll get), I doubt it would match a mildly modified c1 on power output.

But a home-built turbo kit would be cheaper in the long run for the y7 with intake/exhaust added to aid in producing extra horses.

I didn't know that about the header haha...but ya the reason I ask is because I'm wondering if putting a bunch of work into the Y7 would be worth it over swapping to a B18C. I mean, I know the B18C is better, but the cost of the swap is pretty pricey.

Theaverage d-serieskit (14b turbo @ 8psi, with a good tune) should be making anywhere from 175-210hp (tons of variables). A b18c with i/h/e MIGHT get up around 185whp, but will still have no torque. I always bring up a local guy's motor when the b18 conversation arises. He had a b18c5 with a mod list that Honda boy's dreams are made of. Putting down 230 whp, and an earth shattering 135ft/lbs of torque. That car, against my y8 @ 8psi and roughly 192 whp, 180ft/lbs of torque, my car would walk all over him.

hp sells cars, tq wins races. Not to mention, boost is way more fun :D

RE: D16Y7 Boosted vs. B18C1
 

I think I'm going to have to call bs on walking all over a built NA type r.

And if tq wins races then everybody would be driving diesils. Tq gets you off the line faster.

RE: D16Y7 Boosted vs. B18C1
 

Well, thats your opinion, and thats fine. Obvoiusly I can't run him now because my car is on it's way out of my garage, and no longer boosted. Plus, he sold his motor.

Like I said, he was putting down 230ish whp, and only 135 ft/lbs of torque, it wasn't that fast. IMO, Hondas without F/I are filled with what I like to call "hollow horsepower." You can feel it, it's there, but it just doesn't have the pull

RE: D16Y7 Boosted vs. B18C1
 

agreed, a boosted d- would beat a I/H/E b18c1, i could keep up with a b18c1 with basic bolt ons with my 8 valve. let alone when i put the b7 16valve on.

RE: D16Y7 Boosted vs. B18C1
 

Ya, numbers speak for themsleves.

RE: D16Y7 Boosted vs. B18C1
 

What if the Y7 was bored and the displacement got up to around 1900cc? Would that definitely push it over the top of the B18C? Also, I'm wondering what you guys think is a good price for this to be done?

RE: D16Y7 Boosted vs. B18C1
 

Another factor to consider is altitude. If you're up high, boost retains power better than N/A.

RE: D16Y7 Boosted vs. B18C1
 

I have a B18C1 and i have beaten boosted single cams, they were running somewhat low boost sooo

RE: D16Y7 Boosted vs. B18C1
 

The Y7 makes more powerr on 8-10 PSI. Than the GSR with I/H/E.
But however there are so many variables, What Turbo, what mani, what fuel managment and what kind of tune.
For example: SovXietday had a D16y8 T3T4 turbo, and ran at like? 8 PSI was it?
He put down 210WHP, and 167 ft lbs of TQ.
He also ran a Jackson Racing Supercharger, and only put down 146 whp ( i think) and 111 ft. lbs of TQ.
So you can't really just say Turbo/Supercharger.

RE: D16Y7 Boosted vs. B18C1
 

Probably ****ty drivers and/or weak tunes ;). Aint no way an N/A b18 was beatin' my single slammer

^Is that before or after the rod went thru the block? Just kidding forty!

before...ass!:D

RE: D16Y7 Boosted vs. B18C1
 

I would concider the swap, if u go boosted and u don't know wut ur doing ull run into a lot of problems, u do know u have to get ur ecu chipped, get a tune and upgrade ur injectors rite, jus becareful it sucks wen u need to go somewhere and ur car needs repairs
