Help on turbo cams for B16A

[TEGNO1]

Hi i am unable to decide on which cams to buy for my B16A turbo. I am hoping to recieve input on what cams were used for a B16A turbo build, No guessing on info youve read please, i need proof with dyno sheets, and having actually driven the car finished, Were they laggy ,bad idle, responsive etc.Hopefully with enough different engine cam combinations given, i can decide on a set of cams for my motor.

yeah, well, you'll need to provide detail on the application before anyone can comment ......................

Ok , my specs so far B16a no sleeves, crower rods, standard bore 81mm JE forged pistons, cast short runner exhaust manifold, HKS 2835R turbo, 38mm turbsmart wastgate 8 psi spring, front mount, msd dis4 ignition, microtech mtx8(upgrading to Autronic smc) JG edellbrock victor x manifold, 65mm JG throttle body, 1000cc msd injectors, aem fuel rail, standard top end so far made 205kw at wheels at 19psi. thanks.

[ProECU]

I think you should be worrying about turbo before cams mate...

19psi stock sleeves on a baby turbo...... good luck

[TEGNO1]

True they have been Known to move, but also standard honda sleeves can handle a fair bit, and the turbo is rated at 420ps by HKS, ive read cars using one or two of these turbos, making 280kw rear wheels plus(0ne turbo, 550kw rear wheels 2 turbos), i can get you the info if you really want. but im struggling with cam choice at the moment. later.

[Weq]

a GT28 is rated at 320hp. ur pushing it it at 19psi...

BUT anyways, the americans love CTR or TypeR cams. cheap upgrade and good power. But yeh, any NA cam will do good things in a turbo motor, just get cam gears while ur at it so u can dial them in.

[Slow96GSR]

ITR and CTR cams aren't the least expensive way anymore, at least buying them new. Most companies offer discount at the end of the racing season to make way for new parts/models. Crower, Toda, and Skunk have sales going with Crower having the better deals, almost year round too. Here you can see the that you might want.

Toda is down for updates.

Hi no its a HKS 2835R not GT28 (under)rated at 420ps by HKS, i might have a set of type r cams, I was hoping for info such as say my car B16A with and standard cams has 205kw at wheels, with the standard cams thats what you would expect with a built bottom end and 19psi around 200kw to 220kw (depends on tune etc) Drivability just like standard,power drops of 7500rpm, v-tec kicks in around 4500 rev limit 8100, When 4500 comes its a huge rush of power and lots of wheelspin, and youd better be lightning with the gear changes 8100rpm comes so quick you dont know what hit you. Anyway has anyone had or experienced a setup similar to mine but with crower stage 2 cams, toda spec b and c cams, what was the rev limit drivability,when do they stop making power, v-tec switchover, feel of the car etc, Toda states on one of there medium budget builds a B16A should make around 280kw to 295kw with spec b cams, if i get the type r cams i will post a before and after comparison, and yes i am definetly getting cam gears and all the other stuff, but i want to get a set of cams that i will be happy with.Oh ,here is the link to the specs on my turbo to just to prove im right sorry http://www.hksusa.com/products/?id=711, thanks again.

What year model is the head/engine you are using some of the early B16A Auto cams where smaller.With your current setup there is something not right as you can make upto 250kw with STD B16A cams and head if the rest of the COMBINATION is right,and from you list of mods this should be making those numbers.I have seen 280kw out of a setup very close to yours he then changed to Toda Spec-C cams and valvetrain ported the head went for a better design exhaust manifold and made over 350kw.I have read over your setup again and really think there is more room for improvement in changing some of the setup rather than cams.

hi first gen B16a 89 5 speed cable box, 250kw didnt think that was possible on standard cams,350kw using,spec c interesting,what boost?, any feedback from these peaple, what did they think, regarding my setup what would spec c's do, So far the best options are crower turbos, toda spec b or c, ITR cams, anyone used these or other cams,with a similar setup to mine, trying to get info on characteristics of each cam, thanks again.

[Waggy]

From my research, for a street setup, ITR/CTR cams are the best cams for boost. That's why I was going to use them. It really depends on your power goals.

[Weq]

I dont care how HKS 'rate' it, a compressor that small cannot support it! WHat are the dimensions of the wheels? have u measured them...

MRJDM made 240kw on 18psi, std cams. This was with a 500hp turbo though, t3/t4 .57trim, stage 3 wheel, .63 A/R. This setup made power all the way into the rev limiter (8200~). On the dyno, dave expected to see another 40kw with type-r cams and gears... Search in the members rides section for his full setup.

What are the specific's of the motor? Compression ratio? Intake manifold? Exhaust manifold? Piping sizes? etc....

[TEGNO1]

Look when i get the head done, i'll let you know at what power level the turbo runs out.(maybe i should start a thread to see if anyones used this turbo before and what they got out of it) Ive got some excellent advice and info from DYNO DAVE ,(thanks), and there's a few important things i could change such, as exhaust manifold and wastegate,but it looks like im going to start with the head using toda spec c's, , I cant give you the info on compression, pipes and turbo because im not 100%, LATER..

[FastFwd]

dont know if this helps....

I Have almost finished my project. atm im running b16a2 But japspec so its b16a 1999 model out of a jap sir. stock head work with Toda adjustable cam gears. i have JE pistons with scat rods. stock bore size. running T04e garret turbo with Power FC ECU. front mount and tial 38mm gate with 3inch turbo back exhaust. I got mine tuned at 220hp at the wheels a couple weeks ago on 7psi. rebuild was done 2-3 months ago.

ive got 550cc injectors with walbro fuel pump sitting at home ready...i just want to clean up a few things. before looking at boosting it more....i want to get it safe on 20psi.

i can let you know how things go then. See the difference between the older gen b16a to the newer gen b16a

Ohh btw deffinatly better choice with the smaller turbo....i hate my turbo, sooo laggy

[TEGNO1]

Hi thanks for the info and please let me know how you go. what exhaust manifold are u using and being a sir motor is that a civic type r motor or just a standard newer b16a with standard cams,, i would like to know what power you get when you tune to my level around 19psi, That way i can compare. My car kicks in around 4-4500 rpm hard, But i dont notice much lag cause its gets to 4000rpm so quick, when does your turbo kick in,how does the car drive, When i get the head done i can also let you know how much more power i made with the head done , thanks and hope to hear from you soon.

Well i dont know forsure, i think its just a b16a newer 99 model with stock cams. i have a custom ram horn style exhaust manifold, which im actially getting new brackets made on it today because i recently had slitting problems with it.

i havent had the adjustable cam gears tuned yet. ive just chucked them on the stock setting and got the tune done with fuel management not the timing soo i might be able to get some more HP out of that.

i have a t04e which is a laggy turbo....i really dont like it but you have to love it from 5000 - to 9000 RPM's because once its on full boost it doesnt drop power the slightest bit aspecially when vtec cuts in. i would say it would take a little longer on my car cos the turbo takes a bit longer to spool up but as i said once its on full boost around 5000RPM you need to be quick on your gears because it hits 8500+ RMP's sooo quickly. and wheel spin doesnt help that factor either.

and which i was suprised with is mines a b16a 99 series 2 and theres a civic on here selling a turbo kit very similar to mine that was on a h22a and he said that he got 224hp on 7psi and mine got 220hp on 7psi. and if i got a better tune with my cam gears and such i think i could have been around 224 - 226hp mark and thats the diff from a 1.6 to 2.2 vtec motor.

but then again they have alot more torque.

anyways ill stop rambling...ill get back to you when ive done a tune to 20 psi

[TEGNO1]

Mmmm maybe im gonna have to change me exhaust manifold too, my car made around 165kw at wheels on 0.8bar which is around 11.5psi (tuned to pass emissions) cant really compare this way, but your right the rev limiter comes so quick when v-tec and turbo spools up. Anyway let me know when your finished, thanks.

Anyway let me know when your finished, thanks. You have to ask your self the question of how much power you want to make.
and how much money you have to spend.
I myself made power without breaking the bank..
research is your best friend.
My setup was put together by weq and myself and a GREAT tune by DYNO DAVE
and i didnt make big power cause i had the best or biggest parts.
i made power cause i done my homework and chose the right gear.
regards MRJDM

[TEGNO1]

Hi can you provide details on your setup and power please. To answer your question, ive got a problem and that is i dont set a budget, i just buy parts until i'm happy(not good). It scares me to think sometimes that almost every part of my car is worth more than the car itself, but i'm out of control now, and regarding choosing a setup it would be better to start from scratch and build something with the research done. That is what im trying to do now with cam choice, the bad thing is im stuck with what i have now and have to work with what i've got. I can gain power with every part i make improvements on however i dont think any part i change will make an improvement as much as doing the top end of the motor, and im hoping for about 260kw - 300kw at wheels (dyno dynamics), thanks .

[TEGNO1]

Hi i just bought some Toda spec b cams and cam gears, they came up cheap second hand, still have to get the rest of the gear, when its done and tuned i will post before and after dyno sheets, wish me luck, and isnt there someone else out there with these cams + turbo or any other cams that can provide some dyno sheets or info, later.

[BALIW]

Yo bro i think u should be more worried about the power u making at 19psi rather than getting big cams. Like dynodave said u should be making shit loads more power with the set up u have running that much boost. I have a EK civic turbocharged, but engine is more built for drags and serious power. But befoer when i had a stock engine and just bolted the turbo we made 164kw atw and thats at 6-7psi tuned by dynodave. but now im hoping to push out 400hp atw when i get my beast passed for EPA(heheheheh).I think u should go back to whoever built ur engine and ask whats wrong bro.

Anyhow before u buy the cams make sure its for turbo applications. also u must do ur springs, valves and retainers etc to suit the cams. otherwise say bye bye to ur engine if u just wack them in without doing the rest, doesnt matter if they are TODA etc:)

[TEGNO1]

Yeah by what peaple have been telling me i should be making more power, i figure im losing a fair bit due to exhaust manifold and my cams were the smallest of all b16A's, i bought the car with bottom end already done, i am doing the whole top end and replacing the exhaust manifold and maybe wastegate, these changes will make a big difference along with the Autronic computer, anyway do you mind telling me about your setup, and is that your civic on your avatar, later.

[BALIW]

Yeah bro thats my civic. it was in front cover of FASTFOURS 2001 or 2002, cant remember its been a long tym. U know what even if u left your stock head on it should be still making more power than what u have now. Doesnt matter if u leave the head stock. u know what before i did my B16A i built a d-series SOHC. I only did the bottom end and ran 19psi and made 260hp with stock head, so by that it should indicate that ders something wrong with ur set up.

Nways bro just wait for my return its been 3yrs now i've taken my beast of the road, as i got done by EPA hard and also i did more work to my engine. I'm just about done passing my beast from EPA, they have given me hell:thumbdwn:

My set up is pretty much built for power and the straight line. dont want to reveal to much, just wait for it i will post everything as soon as i get the car back on the road. All i can tell u is i'm running a HKS 3037GT Pro Series TURBO.

Keep in touch mate:)

[TEGNO1]

Yeah my mate at work knows you, told me bout your car awesome,cant wait to see your set-up, i have a copy of that mag too, and i just passed emmisions test myself all you need is a good tuner, it is down on power compared with some, but once i change the exhaust manfold and do the top end along with a tune and i,ll also try and find out if there's other area's restricting my power such as intercooler, wastegate etc, but i'll be happy with the power once i do the head after that i,ll need a bigger turbo, later......and i'll definately keep in touch.

[BALIW]

what ecu u using again? I tryd all the tuning but they really ****ed me hard bro. Nways i'm using a MOTEC400 now so that should solve all the bullshit and also that means more POWERRRRRRRRRRRR:)

Bro i have a complete microtech LT10 for sale, i want $1000. Comes with the harness. I havent used it. Its good for any Honda engine. It has vtec control etc. Ask around for me bro.

Thanx. call me some tym mate 0414509339. Maybe u can take me for a drive in ur beast so i know what else u can do. What area u from cuz?

[BALIW]

Bro maybe u want to get my LT10 of me. I have not use it. Just wired it to start the car but after that i got the motec. reason is that the car is going to be use for drags so i cant afford any mistake. I want $1000 for it to $900. Its brand new. This ecu can run seperate coils if u wish later on. If not ask around for me bro.

Thanx

[TEGNO1]

I was running MTX8 does the job well, but i need something with a bit more control, the microtech lt10's is excellent, but im gonna go with Autronic, later.
