Is a skunk inlet and throttle body a good upgrade for a b18c-r engine

[adamek9]

yea ok they dont spend nothing on research they just think hmmm il do that and it will do that corse they research it
and a manifold does help stainless is smoother than cast iron so its a better flow rate in exhaust also the bends are not as sharp which help the flow rate so like i said in the 1st place all these things add up and when its been mapped you can turn the air to fuel mixtures up so you get your gains i.e. out of your mani n inlet n air filter n all the other goodies you have on your car

Turbo up in other words??

Is there anything for like 4/500 quid that will give my car that extra bit of umph? Or is the turbo the only thing worth thinking about?

Well a turbo will undoubtedly be the best option if you want big power without a ridiculous amount of money. I'm personally one of those people who thinks a Honda should be N/A as thats what the designers and engineers who spent years developing the engine wanted it to be BUT N/A tuning is expensive so you won't gain a huge amount of power without spending a lot and of course careful planning.

Make sure you've got the basics sorted first so decent exhaust system inc. manifold and a decent intake are vital. Assuming thats been done then it really depends on what your wanting to do. If your keeping it N/A then you may want to upgrade to some mild cams (if your just wanting a bit more power) but bear in mind you'll need to buy everything to go with it (uprated valve springs, retainers, mappable ecu etc.) so will probably cost more than £500 in total

Yes we can assume they have had extensive R&D carried out during development but no where near as much as Honda (they just simply don't have the same budget). The stock intake manifold is the best you can get for engines that haven't had major work. The Skunk 2 and others work well for different applications- for example if you install some crazy cams then you may well see gains from changing the manifold, it all depends on what you've done as to whether it will match up well. But just changing this manifold and remapping will lose you some horses. Theres also a reason why they cost far less than OEM ones

Can I ask why the hell are you talking about the difference between a "stainless exhaust manifold and a cast iron exhaust manifold" In an Intake and Throttle body thread???

Goodies???



I give up! I have tried to explain why a larger throttle body and different design Intake manifold is not a worthwhile mod on a standard engine.

But clearly you seem to know what your doing, so feel free to go spend your hard earned money on these "super amazing garanteed 15hp+ parts"

Can I just point out to poeple that right at the end of the page on a thread there are usualy 4-5 "Similar thread" Sujestions.

Some of you would benifit to read them, as they cover this many times. In fact it has been covered tones of times. But they are a few examples. Also just to add some of them date back to 2007 so its not like this tuning information is like "Breaking News" haha. The basics of engine tuning principles will always stay the same!!

ok ok someone give specs of :
stock itr im
skunk2 pro im
blox v2 im

need :
plenum size
Runners volume
Runner length
total manifold volume

then we can compare,chat and say stock im is better on that set up coz this and this....

no skunk2 or blox give these specs so lets make another thread asking if skunk2 is better than stock itr ... pointless i agree.

if stock is better then there is no need of tuning
why buy a toda header ?

^^ this may beat s2 but cams ,cr,cc etc makes a big role on that

 

[KieranEG6]

Why do people keep referring to exhausts?
Nobody said the stock exhaust manifold is best.

Im just thing to say on a stock motor the standard ITR intake and throttle body is optimum for the setup. Changing to an intake manifold designed to flow more with cams and tuning will only shift the peak power further up the rpm and loose out on usable mid range torque.

I clearly stated in previous post that this wasn`t the case. Actually kept high end power and torque and greatly improved down low. I have no dyno plot to back this up, but i don`t speak sh*t.

The S2 IM and TB were designed to work with their cams and valvetrain upgrades. simply bolting on a bigger tb and im will not cause much of a power increase at all. you might get lucky once the car is tuned and see a small increase in power but untill you install the rest of the parts your wasting money. Skunk2 designs their parts to be used together but sell parts on their own because its easier to make money that way.

I use a lot of S2 parts on my car and every other honda i have ever built. They make a great product and stand by it. I have spent hours on the phone with Dr. Charles disucssing suspension set ups. I have spent time talking R&D with the company and have friends who are sponsored by them. in all that time and talking with all those people it has been stated time and time again that for the best performance gains that you need to use their complete head package parts that they offer together with a tune to see any kind of significant power increase.

if you are looking for some sort of bolt on power increases then the base intake and exhaust are the best option. i know alot of people prefer the mugen or arc box in europe however i have found better useable power gains with the J's racing/password:jdm intake along with the velocity stack. when it comes to throwing on an im and tb i say wait untill you upgrade the cams and such.

using different oem tb's on a stock engine is a much better choice. if your that worried about airflow give your stock im and tb a small port and polish, however no need to go to the S2 sizing without engine internals.
