mini me head swap coming soon. b16s watch out!!!

Sohc Driver

whats a mini Me swap?

Endless

Putting a VTEC head on a non-vtec block

AudioXtremes

yeah its when you take a d16a6 block and put a d16z6 or d16y8 head on it. more hp than just a d16z6 or y8

PolosportZ81

is it better to supercharge a SOHC or turbo???

TurboSedan

DO NOT ASK, DO A SEARCH!!! THIS IS A DEAD HORSE!!!! NO OFFENSE!!!

PolosportZ81

yes i kno this, i read all the post in the FI fourm, everyone says do a search i just did a search on supercharged sohc...came up with nothing....i know most of you here are Turbo guys but i'm just looking for opinions on superchargers.....geesH

DIZASTICAL

matt at MMR has a sohc and runs a 12.88 in the 1/4 . to me that is the **** ! it is all motor !!!!!!!

BenenEK

boosted sohc. cant beat it for the money. built bottom end. other than that stock d16z6. ran 12.30's all day long. With a best of 12.32 @116. 14 psi.

RTRcivic

yeah but the money you spent would have bought a reasonably fast stock motor and could be motified the sohc would already be modified the b16 would be faster with minimal bolt ons

A b16 with bolt ons will not be faster than a boosted SOHC, are you on crack? Please someone call the dumb police!!!!

spyder

I've got a question. Why the hell do people always use the b16 for comparison in this type of argument???? The b16 has NO torque, just like the d16. As long as you're gonna do a swap, screw the b16 and go with a decent b18 engine. choose which one based on what you want to do: b18b for turbo, b18c1 for high compression, b18c5 if you're a rich punk with money to throw around.

Another point. You say that for the price of a b16 swap, you can have a SOHC that will blow away most b16's. To start with, it will NOT blow away most b16's, it will blow away a few of them...whose owners don't know how to drive. Second, assuming the b16 swap and the built d16 get roughly the same performance. Did you ever considder that the d16 is now basically maxed out while the b16 hasn't even been modded at all????

A little common sense here please...

eg6ajk

there are many valid, good points, D16 is excellent as all purpose motor, its fairly quick, its cheap and easy to get.... you will not find crazy power with it or pull some super number but will give a good peppy feeling for its money.....
b16a excellent motor, but defiantly don't think its all that for drag racing, its meant for circuit driving, where high revs, and upper rev power shines......

I had many motors, all I can say is that, depending on a purpose all have some advantages....so instead of fighting, lets get along...enjoy, the cheap alternative to the JDM madness and all get a d16a/z/y or even ZC

TurboSedan

Hmm....ok, so if I put a $3500 turbo kit on my SOHC and run say 8Psi you do not think it will blow away the same exact car if the money were put into the B16A swap? My good friend who is a better driver than me, has a 00 Si with I/E. I have a 97 EX with an AEM CAI. When we take off, we are even until he hits the top of second. By the time I hit the top of third at 85mph, he is just one car ahead of me. When I turbo my EX I will blow him away, and he is a great driver.

Also, even if the B16 has a bunch of bolt ons, it may get 150-160whp. A well built and tuned turbo D16 will come out at about 175-185whp at 8Psi. Hmm, who do we think would win?

P.S. I am not flaming you, just dishing out food for thought.

spyder

a b16 swap doesn't have to cost anywhere near $3500. If you put a little effort into looking, they can be found for much less than that. I agree that bolt-ons do very little to a b16. but why use bolt-ons? turbo or supercharge it!

Example 1: spend $2500 on a turbo for the d16. sweet, you've got power. now you get another $2500. What to do now??? You can't turbo a car that's already turbo'd, can't supercharge it...you're stuck (except maybe n2o and some internals)

Example 2: spend $2500 on a b16 swap (yes, they can be found for that). sweet, you've got power, not quite as much as the d16 turbo maybe, but still enough if you lighten the car a little. now you get another $2500. Aha! now we can add a turbo or supercharger, and that equals more power than the d16 could get.

Basically, the d16 turbo is fine for the short run, but you WILL get bored with it, I can guarantee it. If you invest a little in the future and get a b16 (or better yet a b18 series motor), you will have more power and save more money and have more fun in the long run.

what is MMR.. any links about this guy or his car??? full race car? full interior? street car? etc.etc.. 91 octane. ? ? ? ??

but full race 1.5 sohc has ran 11.20s allmotor

TurboSedan

Well, I believe that I will keep the SOHC turbo for at least a few years. Yes, years. I am not sure how bored I will get of it when it is sleeved, 9.0:1 pistons, forged rods, and running around 18-20Psi with a Hondata. Though all of that botton end/sleeving will not happen until 2003 at the earliest.

96 SOHC VTEC

Sorry Spyder. Gotta agree with CivicFerio on this one. There is a guy I know who has spent $2500 on a complete Greddy turbo package with intercooler and other goodies for his 98 Ex and so far his best time is 14.2 With slicks and some better driving he is easliy hitting high 13's. Now you can't tell me if I swapped a B16 in with a few bolt ons that I would be running anywhere near that. He is running 10lbs of boost btw with LOTS of room for modifications.

spyder

I agree, there is still room for modification, but a b16 which is non-turbo'd has even more options and more potential.

I'm thinking LONG TERM here. You're thinking short term. Okay, if you're only ever gonna have $2500 to spend on your car, then yeah, turbo the d16. But if you have $2500 now and know that later on you will at some point have $2500 more, then the swap is a better idea.

Yeah but you still have a boosted motor versus a stock were are you going to go from there. Who would win if the b16 was boosted? get my point. dohc modified correctly would beat a sohc with the same mods.

TurboSedan

I KNOW THAT! I never said the B16 would be turbo! Any idiot knows that a turbo B16 beats a similar equipped turbo D16. Sheesh! $2500 for a turbo kit doesn't cut it for me anyway. My custom kit will run me about $4-5K, including the Hondata Stage 2B with a OBD-I conversion + RC 440cc + CM Stg 3 clutch.

If you are on a budget, build what ya got. Whether it is a D16, B16, B18, B20, H22, F22.......whatever. Also, as said above......if ya blow the D16 it will be much cheaper to fix it than if you blow a B16 or B18. Isn't that considered a long-term expense? I would think so.

fsp31

Bottom line is, everybody is RIGHT!!! 98CivicFerio and Spyder BOTH!

I think I have a solution....

What we're really talking about is HP per dollar spent. You can plot it on a graph if you want. For the sake of this discussion, let's plot HP on a vertical axis (just like a dyno chart) and $$$ spent on the horizontal axis.

If you'll notice, the line is *curved*, not linear. At the low end (not many mods), the HP gained is relatively cheap (curve is "steep"). But as HP increases, the relative amount of $$$ invested increases, so your "curve" starts to flatten out. Everybody with me? Ok, HERE'S THE ANSWER:

Do a graph for a B-series, and do another one for a D-series. Then put both lines in the same graph. The D-series chart starts out ahead of the B-series in terms of $$$ spent vs. HP gained. But, as HP increases, the D-series curve starts to flatten out *before* the B-series does. So, at a certain point it actually becomes more cost effective to work on a B-series motor.

If you are content with gains made before the crossover point, then stick with the D-series. If you want power gains beyond the crossover point, go with a B-series. Now we just have to throw around numbers until we determine that point.

turbo by itself is just okay, but either platform on a built block makes a big difference. Even if you go the B16 route with turbo, you should really build the block. Not arguing, just saying. Both require you to build the bottom, both ways will be pricey. If you can afford it, the B16 is better. But for those like me, the d16 will be just fine.
