Im in the process of building an all motor setup: This is what im running

B18C with 84mm bore ALL JERRY BUILT
Golden Eagle sleeves
Eagle rods
Honda bearings with type r crank
JE pistons 12.5:1 compression
Apr Rod bolts and head studs

B16 port and polished head by alaniz
Complete Buddy club valve train with stage 3 spec 4 cams


I know that the intake and exhaust manifolds are vital inorder to gain as much power and not to restrict the motor of its potential.

I was considering running ITBs but im wondering if i can get better results from using an intake mani.

What would you guys reccomend?

afternoon bump

Peopl must have loads to say about this topic!

 

i guess since no one else is paying you any attentionto you, i will say that dyno tests have proven itb's have increased wheel horsepower about 15-25 hp then intake manifolds on the same motor same everything(atleast thats what i have read on H_T). I know that if you search itb you will find SOoooo much info on this subject, thats why people are not responding to your question.
Thats a sweet setup though, very cool What are you putting that nasty beast in?

 

Its going into an EG shell! Thanks for the help. I knew that ITBs are a gd idea but as some people have said around here that loads of people seem to be selling there ITBs within 6 months or so.

Ive done a few searchers and just keep finding crap info... I also searched intake manifold and exhaust manifold. And nothing gd really comes up.

 

people seem to make good power with basically any of the popular aftermarket intake manifolds, such as the Skunk2, Blox, AEBS, and the JG Victor X. You gotta decide which one you wanna run. As far as exhaust manifolds, you can search that topic, there's been numerous header threads about great headers. How much power are you planning on making? If you are planning on making big power, you might wanna run a bigger cam than the Buddy Club Spec 3, unless you were talking about the BC Spec 5's as the stage three.

 

as i am from the uk i might be typeing in the wrong words in order to get the right results. Instead of manifold i will use header and see what results i get. I am going for as much power as possible with a crazy explosive vtec crossover. I was thinking of going to the bc spec V Extreme. But how would these work for daily driving. Or should i just go with Spec IV??? Obvioulsy ITBs would be best with such an aggressive cam

 

ok ITb's are NOT proven to make more power than any of the great manifolds out right now so please stop posting HT bandwagon jargon.

i agree completely with slowsleeper about the manifolds and headers and yes you may be using the wrong term to search if you havent found anything yet. i also think that you should stick with the bc4. this is your daily driver and im sure the bc5 doesnt like to idle or stay below 5k. people have been doing well over 200whp with the 4's plus i would think that youd need more compression for the 5's. hope this helped

 

bullshit they aren't proven almost all allmotor drag cars have itb's, am i wrong?
It's all about tuning it correctly. ITB's are going to give you more power. I have seen many itbs that are amazing.

 

Thanks for the info Unknown. I had a feeling the 5s would be a little too extreme. And also london is **** as there is a lot of congestion and traffic, so a gd idle is very important. I think i will invest in the 4s. Also it says the 5s are not for road use. maybe because of the idle issue.

Ive been doing a bit of reading and it looks like ITBs on average in ever story are performing roughly 19bhp better than any top manifold. It might not be proven but it does look like it.

Im trying to look for a nice set of ITBs for around the $1000 mark which seems realisitic enough. If i find something nice then ill snap them up.

Is TWM one of the best makes for ITBs??? can anyone reccomend anything else?

 

with that much compression what kind of gas do u have to run... and with an OEM 3 layer head gasket do u have and deck clearing issues??? curious becuz i was getting jdm itr pistons but what also thinking ctr pistons but was told i might have deck clearing issues and need higher then my 92 octane gas....

 

If you are in England, talk to Simon @ Jenvey about ITB's and to Kent about cams, and Alan @ DTA about engine management.

 

DonF how do you know so much about the uk tuners???
Here in the UK i will be running 100 octane gas... but i supposedly heard the quality isnt as good as the states. Although we have better octane fuel it is supposedly cleaner and more consistent there compared to here.

 

Bedause the DTA ecu's are better than what I can get here. The Jenvey's can be made for what engine I am putting them on, and make more power than the TWM;s with lass work, and Kent made me custom B-series cams 11 yrs. ago when no-one here had any. Neil Brown was doing the British Touring car Honda motors, and the F-3 motors.

 

dont get itb's they're only good for throttle response not horsepower. get you a skunk2 mani or blox 68-70mm throttle body port to match intake mani to tb and call it a day.

if you want proof that a finely tuned intake manifold can produce more hp than itbs then go check out some of the k series tuning. ips is making a manifold right now that is suppsoed to outperform itbs by quite a bit and tests have already been done to prove this.

donf just gave you some great advice as always so i have nothing more to add.

Stop talking out of your ***, you have no idea why ITBs make more power than most intake manifolds, all you see is ht bandwagon crap and 4 throttles and you wet your pants.

If you can give me one theoretical advantage of ITBs over a full intake manifold other than something retarded like "duh, 4 throttles flow more air" then we can talk.

For now, think about the fact that a well-designed custom intake manifold where plenum volume and runner length are formulated to match your exact setup there are advantages that ITBs don't have (see jd3jdm's h22 build). If set up correctly, pulses in the intake inside the plenum can "share" the burden of getting air to one another whereas open ITBs can't "share" the burden of getting air to one another or "help" one another....I apologize for the vague terms "share" and "help" but I really don't fully have the knowledge to state that any better....ask the airflow guys about that...Brad at RLZ could write you a book on it

 

OT:

D series &gt; all

 

is the victor x edelbrook mani better than or perform better than the skunk 2 in any way?

victor might be too much unless you have a built motor that revs high

It depends what you consider big power and restrictive. 200whp@ 6000 rpms is big power for NA, but peaking 240whp@ 8500 rpms+ is not big power IMO. You can make 240whp@8500 rpms with most aftermarket manifolds, similar design like the ITR/AEBS/Skunk2.

Start with OEM boltons to see where you need more power and you'll find your answer.

I.

 

well look at my setup at the top ^^^^
Im going for big power and i have a completly fully built head.... i will be revving to 10000rpm or so with my valvetrain. I have a fully built bottom end which can take it too. i am aiming for 220whp. I originally though i would use ITBs for the best air flow but if i can get the same results from an intake mani, then i can save money and have possibly less probs with tuning.

lol ok superman you can stop lying to yourself

 

well I'm gonna rev to 11000 so I'm gonna make more hp

so eat that type B16
