i agree with Pete, but can't we just all be friends and agree headers is the common term? :P or least from what ive heard.... :oops:

A good cold air setup, plus a nice exhaust setup, what people don't realise is the stock exhaust manifold ( extractors / headers) flows very nicely !!! and most cheap aftermarket exhaust manifolds flow WORST than aftermarket. The same goes for Throttle body’s people this wow massive gain, proven tests has shown there’s more benefit in changing your intake manifold than your throttle body.
Spend money a ECU and tune more power into your car by advancing your ignition and perfect air fuel ratio, at the same time increasing your fuel efficiency and driveability.
Other than that, your going to need to spend big money to make much more power from NA, or go Turbo.

I agree here, best bang for buck would be basic exhaust + intake with a ECU tuned to suit it.Quote:

also, does this "ECU + other mods = best bang for buck" only apply to certain cars? or would it benefit even a 1.8L non VTEC DOHC like my GSi?
Jon...tis ben the Ute kid here :P
Ok , basically...teh ECU is the computer managent system of any EFI car...its a small , sandwhich sized box filled with diodes , circutry etc - its the brains of the car. You would find it under the passenger side seat or at teh front lefthand side of the passenger's feet - What the guys are talking about is using AFTERMARKET ecus and/or piggy back systems - which basically take out the ECU of ur car, and replace with something newer, more efficient or run a stock ECU with a piggy back computer hooked up as well.
This is turn can enable you to play around with fuel ratio settings etc etc( ofcourse with the aid of ECU software on a handy laptop) to do with the engine , and hopefully gain more HP thru altering factory specifications.
Put it this way - my mate Yonas wit his blue EG5, same engine as ur except 200cc less capacity...BUT with a aftermarket ECU (piggy back) and extra breathing mods ( CAI , exctractors, etc) it has been tuned to rev till 8200rpm...and im sure he has altered the peak power to be produced higher in the rev range -
Result ? A dam quick NON-vtec ...beats VTiRs , and can beat a stock itr off the mark... Well , dam quick anyways ! ( Yonas...please feel free to alter or correct my comments :D - ur car is dam quick anyway!)
Jon , im sure u can pick up a aftermarket ecu and just strap it on ...and feel a difference - but im hoping WIN gets one so he can finally beat you :P
thanks for that ben. really concise and simple explaination. perfect for newbie like me :)
is Yona's car and mods a "regular" sorta modded car or something which is quite unique? AKA is this sorta thing done alot. Cos i havent heard the ECU mentioned alot when i've asked bout performance etc.
So would this mean if i threw a full exhaust/headers/CAI and ECU into my GSi i'd be looking at high gains too?
how much would this all cost me? Where would u get an ECU fitted/installed and tuned etc? someone pls tell me more... im interested :)
hehe... yeah Win get an ECU. i wanna check these things out. who else here's got one and can gimme more info? btw, i didnt win against Win. i think it was a void run :roll: (cant wait to go again.. lol)
Tis no problem brother ! Well , I cant comment on Yonas's car too deeply , as i dont really know what goes on inside! But , i can tell you that the external mods that he does have , you should most likely get !Quote:

With the ECU , Yonas uses a piggy back item , with an ECU . This is a good bet - but for your car to truely FLY above stock all your money has to go into TUNING. Yonas's car is very well tuned - alot of time and effort has been spent on his car i believe - and so it can really rev out and fly :)
You cannot tune it yourself - as noobies like us need a pro to muck around with A/F ratios etc - totally transforming the car :)
If all this can be done on a 1.6...surely for your car it can only get better 8)
Research "after market ECU's" in google , or " b18b after market ecu"

Howabout investing in an advanced driving course before heading out to sticking more power into an already potent block? :arrow:
The man has a point...i think MOST of us here should partake into a advance driving course out at Oran park etc...Quote:

I did it 3 years ago , two 1 day courses for around $400 - really good fun ! And worth it too !

haha...for sure noel. i wasn't thinking about doing these mods anytime soon. just interested in how it all works and possibilities for the GSi in the future...Quote:

pssst..... thats ONE person who says my B18b is "potent"...... :twisted:
A ECU is the brain behind any modern fuel injected engine basically a ecu controls how much fuel goes into the engine and how much ignition spark (in a general way) anyway manufactory’s tune every stock car to a point where it’s
1. Pollution friendly
2. Drive ability to produce a smooth none aggressive car (Honda DE tuned the K engine on DC5 to reduce torque street instead of upgrading suspension ! at 2500rpm – 5000pm)
3. Within very safe limits where its almost impossible for engine damage
4. plus many werid reasons..
Anywya as soon as you change one thing on your car ( engine wise ) your engine will not take advantage of it fully unless the ECU knows about the modifications and the car is tuned. Yes you can get some benefits by bolting on things but unless you provide the correct air fuel and ignition your not getting the true benefits. There are many ways to so call tune any ECU the most common but by far the worst option would be using crude devices such as AFC / e manage / Link / uni chip / micotech that intercept signals from the engine and give the engine false readings. (ranging from price from $500 - $2000
These are bad for a few reasons, one most ecu’s auto learn so after a while these piggyback devices become invisible to the stock ECU, something many tuners or sellers forget to tell you, not many people know about open loop / closed loop modes.
Certain brands have more fine tune ability than others, some come with more EYE candy options (RICE) than others, but unless you stop the stock ECU from learning your wasting your money.
On a side not a chip upgrade not tuned for your car are a utter waste of money, unless a device can be tuned specifically from your car in real time on a dyno its not worth its weight in gold !!
The other way is to either fully replace your stock ecu with a aftermarket ecu or upgrade it to be fully tuneable, major names in this upgrade are Motec, Hondata, Autronic. These ECU replacements have much greater tune ability and can support more modifications these and range in prices from $700 – $5000 + These are the ultimate option.

Good descriptive, mods should make it a sticky ... :arrow:
