Here's the deal, I will be acquiring a 99-00 Civic Si in the coming months and am more interested in going all-motor rather than resorting to forced induction for several reasons, those being $$$, reliability, need for speed etc. I'm more interested in taking on the twisties than dragging and I'm not all about speed to begin with, so going all-motor seems to be the route to take, plus going all-motor seems more admirable and challenging in my eyes, but don't get me wrong, to hear that turbo spooling is like music to my ears as I am as much a car fan as the next guy. Anyway, could anyone direct/advise me as to any sites/pics/sample build-ups of an all-motor B16A2?...any B16 really. I would like to learn as much about going all-motor as possible so I can do things right the first time i.e. not rebuilding over and over again. Any advice is both welcome and greatly appreciated. Thanks!

 

Well not too sure on many sites as I do my own work but any good build up should consist of several things some mandatory, some optional:

Bottom end:
Pistons
Rods
Stronger fastening items such as rod end cap bolts and what not
Balanced Crank
balanced rods
balanced pistons

Top end:
Springs
retainers
valves
port and polish
larger bored TB
port matched intake manifold

good set of qualite headers
maybe high flow cat
good free flowing exhaust

It all depends on $$ and how much HP you want to make with the amount of $$ you have.

 

You can get a stoker kit and make it a larger displacement, get JDM valvetrain, such as ITR cams. Get higher compression pistons, like 11.2:1. Get a better intake manifold like a Venom or STR. You can shave your cylinder head for even more compression. Port and polish heads. You can get a thicker head gasket for higher compression too. Balanced bottom end with stonger rods. Upgrade your fuel delivery obviously. You can get more info and parts from places like TODA and King Motorsports, Spoon Sports. They are the ones usually with all motor build up parts.

 

Hey, thanks for the quick replies...I'll look into all that. I would be doing this step-by-step as time and money are limited. My guess is to first start with I/H/E...should I perform these mods in any particular order? Intake, I'm pretty set on AEM. Header, I'd love to go with Toda, but money doesn't permit...DC 4-1? Better header for the money? Exhaust, hi-flow cat with custom piping and 5Zigen muffler maybe? I'm not sure...I've heard that a custom exhaust/aftermarket muffler provides more power than your standard aftermarket catback. Thanks again for your help!

 

-you can make that B16 a screamer with a lot of power just by playing with the top end and ECU.
-mill the head to raise the compression a bit, then there are a lot of choices for cams and a 9000+ rpm vlavetrain, a chipped ECU, freeflow exhaust and a quality JDM 4-1 header.
-you really should look into getting a LSD or your tranny as well, since you like the twisties.
-also, nice tires.. A)32R's are supreme as far as barely legal street tires.
-if you dont want to do the work involved with messing in the bottom end, dont worry about it, Roger Foo's Speedvision winning Si motor had a stock bottom end and stock tranny.

 

First you say shave the cylinder head, also known as milling the head for higher compression, this was a correct statement, so if removing material from the head bringing the combustion chamber closer to the pistons raises compression then how does using a thicker head gasket do the same thing. Thicker head gasket lowers compression, perhaps you meant thinner headgasket. Although not sure why you would use a thinner head gasket if you have already milled the head.

 

hese right, thicker head gasket=lower compression.

 

Good advice I didnt' even think about that.

 

Yeah, I was planning on tuning the suspension first for sure, but I know more about suspension than I do engine mods(which isn't saying much, unfortunately). But you bring up a good point, I want the suspension and power to go hand in hand and complement each other. Is there anything I should definitely do/not do/be watchful of in tweaking my suspension/brakes when keeping future engine mods in mind? For suspension, I was thinking Apex-i WS coilovers, upper front strut bar, front/rear lower sway bars, rear lower tie bar all rolling on some lightweight 17"s with sticky rubber. Maybe throw in a big brake kit, upgrade the rotors, pads,lines and fluid, but that's a thread in itself Anyway, this is all a few months away, I just want to make sure I know what I'm doing when I'm throwing wads of cash all over the Net. Oh yeah, in researching the topic, I came across this site/vehicle...looks like the buildup is going pretty well, but you guys are the experts, you tell me: http://godspeed.hack.net/Projectcar1.htm Any advice/comments are appreciated! Thanks!

 

260 hp to the wheels on a b16 all motor easy. and here people will start saying bull blah blah blah. not reliable what the heck , blah blah. i idn't think you could really do it; damn did i get my s*** stuffed back.

trade secrets my friend. and i'm getting to learn them. whoopee.

A site i think would help you is c-speedracing.com on theyre HOW TO is really good but i think they building a b18c motor but should have the same principles and ideas.

 

you can build a 260whp b16? what is the displacement ?

of course its easy.... not like this stuff is mentally and physically demanding as ; lets say 8 hours of trench digging...

but then its kind of crazy to hear you say 260whp from a b16 seeing that alot of top heads in the allmotor crews are barely getting that with MoTeC and race fuel and ..and..and...

but hey if you know the right people ahcjar103 you could do it easily..

 

Your dyno must have a Facked up Correction Factor...
There's no way your making 260WHP on 1.6L.

Dyno Charts?

No prob, it is all about research and that's why I'm here...yeah, ya think 16"s would be a more logical choice? I was originally thinking 16"s as that would be a good compromise between size and I wouldn't hafta worry about those 17"s weighing me down, I guess. But it's like, only oone more inch and I'd have that extra inch for a kit, but I think you're right...17"s are looking good, 16"s are looking better. Thanks!
