ok as im sure I have made a few people agrivated over my transmission discussions, I am wondering what would be possible to do to increase the performance of my b16b.

The first thing I am going to do is pick up an aem ems (unless someone can tell me a better reason).
Second thing I am looking to do is increast torque and hp, by which means Im not quite sure yet. My guess would be Cams and/or pistons. If I were to go with cams on the stock block (& mugen head gasket) which cams would be best? toda v-tec killers? what kind of gains can I be expecting?

throw some suggestions at me

 

Im not super familiar with the tunning stuff, but, if your not going to do a crazy engine build wouldn't hondata/uberdata or something like that work just fine?

I'd leave your block alone and work on the head. Also weight is going to be a huge enemy with you having the b16b the tq just isn't there in those motors.

 

yeah i know about the torque, found that out the hard way. what cams would be best?

 

What are your current modifications on the B16B?

What intake, header, exhaust?

All of these components will come into significant play when you start looking for more power over stock particularly when you are considering pistons and cams.

 

Unfortunitly there are no cams out there that can be called the best. There are too many variables. If you have a stock b16b block and head and basic boltons then you would bennifit from some tuning. You can use hondata s200 uber data chrome etc. The overall package is what you need to workon the most, not the cams alone. Getting a really good header will benifit you more than getting cams with a "less productive"one. You can expect to pay between 750-1100 for a really nice header ie Hytech, SSR, RMF, SMSP unless you go for a knock off version or someting in the 2-400 price range. If you have a good intake header exhaust combo and something that you can tune with then you may want to look at bc3+, skunk stage1 & 2's or pro1's, rocket cams, there are so many out there. Also another thing to consider is what the car is going to be used for the most since that can influence a cam choice.

 

WHat will the motor be used for?

Also you would probally have much better luck in the all motor forum.

 

the motor is for track only (road racing). Currently is stock with DC header and will have a mugen head gasket

 

Do also note the car has a custom exhaust, I believe 2.5" which has a resonator, no cat, no muffler and dumps to the side just infront of the rear right tire.

 

B18c crank/rods?

 

i have been playing with a 1600cc b series for the past couple years.
good header and cams along with tuning are the most you can really do for it. Unless you have really good compression, itbs arent really worth the trouble.
if you looking for most power for your buck then mos is right..

gsr crank and rods all the way

 

ITR Crank/Rods & TODA C's. Tune. Roll. Repeat.

 

Why the ITR or GSR crank & rods ? wouldn't that change the squareness of the engine? Wouldn't it reduce the ability to rev as high? what kind of gains from doing that?

what kind of gains from just cams? and what about pistons?

 

Pistons won't do much for you, as you already have the CTR pistons which I believe offer the highest CR from the factory. For the AEM EMS, make sure you have a good tuner available. If you have the best standalone management system available, but no one capable of tuning it, it doesn't do you any good. Hondata would be just about as good if there's a tuner around for that and not EMS. The crank and rods will increase displacement and give you more torque (1.8L vs. 1.6). You'll still be able to rev to 8700 like you are, assuming your valvetrain can withstand that (which it'll have to with cams anyway).

GSR crank/rods is the bang for buck superhero for the b16b. Both motors share the same block height. It will change the squareness, but the b16b is too oversquare from the factory. By swapping cranks you're getting .2L with no rpm hit. Yes the rod to stroke ratio will be reduced, and if anything this will help make power. Smaller rod to stroke ratios give the pistons a more favorable mechanical advantage pushing down on the crank. This advantage is most pronounced with long duration cams like the ones that are being suggested

 

ok, but what about when i increase the rpm to 9000 or 9200+ with the cams to get the most power (alongside the upgraded valvetrain)

As with your other (somewhat frustraiting) thread, you seem to be asking more questions than might be appropriate for this forum. Most of what is being discussed has been discussed for years in the all-motor forum and is part of this site's very good and search-able archive. I'm not trying to be a dick, but please use the search function and spend YOUR time doing some reading. Your questions are pretty general and is no "one" answer. A fundamental understanding of the issues and trade-offs involved will be more useful to you than another man's suggested formula for what you should do next.

Please do some reading.

 

I have been doing some reading and searching the past posts, but the greatest problem is that there is so much and it is truly difficult for me to set aside 10 hours to read every post. My questions are general to get some ideas and I am still learning, and with each passing day they will get less and less general. Partial with my questioning is to understand the fundamentals with the issues and trade-offs. I do appologize for being irritating with my posts, but im just new and looking to broaden my knowledge base while working with the car and increasing its potential, kind of a learning on the fly scenario.

What thawley is trying to say is you would have much better luck in the all motor forum.

 

Well you come in here and tell us you want to increase power and torque of your B16B, but you don't know how you want to do it.

I mean maybe you should try general discussion and debate with that kind of narrowing.

Maybe you should start with the bolt-on's. You didn't list ANYTHING done to the engine so I am going to assume it is 100% stock. So start there. Once you get a nice set of quality bolt-on's amassed then I would start with the head, followed by the block or maybe even pick up a spare 1.8 or 2.0 shorty to build in the mean time.

You ask a general question, you're going to get a general response.

 

Kinda goes without saying... a basic lesson of life?

Actually if money is not concern, you don't have to do any reading whatsoever.
Just hand over a large sum of cash, and let someone else do the thinking
for you. Endyn or http://www.importbuilders.com/ or Erick's or RS Motorworks
will gladly take money from you and you can avoid the headaches.

 

toda c's work really good in that motor, some skunk pro2's would probably make really good power in hte higher rpms... those along w/a good header (rmf ftw) and a good tune should get you a good bit more power.

 

R you serious has been down the path upon which you are travelling. Ignore his advice at the peril of your wallet.

You'll have plenty of luck there, especially in the archives.

 

ok very well,

The b16b will be going though a build process, yes I do know what I would like to do, but I am looking for Other suggestions so I dont have to just hand over a large sum of money to get one built up with out knowing.

The build up I have for the b16b in mind is as such.
Balance bottom end
mill the head to somewhere around 12.2:1 compression
Skunk2 Cams (either pro+, which ones I dont know yet, or the old stage 3)
Port and polish head

AEM fuel rail (already installed)
AEM pressure Regulator (already installed)
Skunk2 valves, ti retainers and springs (have)
skunk2 IM -honed (have)

 

geez, you ask someone for a suggestion and you get ridiculed to no end.
