Hi everybody. I've been quoted $1200 for Extractors, Hi-flow cat, New muffler and new pipes. Is this about average? I've also been quoted at a plugin computer from Redcliffe Dyno for $1690 installed and before and after dyno tuning. Are there any Plug-in Ecu's that are rendound around magna's? Oh by the way I've been told by exhaust, ECU and Filter I'm gonna get 40-50kw gain on 98 octain. Is this a lie or is it about right, because I have no Idea. Well thankyou in advance.

You can get a Unichip piggyback ecu for $1200 installed.
I highly doubt you'll get 40 kw out of it all. My ralliart went from 140kw to just under 160kw with those mods.

oh it 40-50kw at the flywheel, not the wheels gain

It might be a bit of a stretch - but I guess it's possible. I've heard that tuning for 98 octane fuel alone is worth 10-12kw. You do understand that it means never going back to regular.

Do you know what brand extractors? (or are they going to custom make them?), type of muffler, and pipe diameter, press or mendrel bent? <--- these are probably the factors which will have most impact on your ability to produce power.

GReddy are widely accepted as being a good programable piggyback ECU for the budget minded modder, but I did hear from someone (Redav??) that they couldn't find anyone in Brisbane who specialises in tuning them.

I'm yet to find someone in Brisbane who specialise in them. Some places can tune them but probably not to their fullest potential as supposedly they have a map that isn't typical of other systems and would get overlooked. If you picked up the system from RPW, (and possibly Philcom), then they would provide phone tech support. I've almost decided to stick with Unichip and get it tuned by someone who is used by the motorsport industry. I spoke to another tuner who said you coudl use the GReddy but at the end of the day, the systems are still doing the same thing. e-Manage is just more flexible, especially come turbo time.

Redcliffe Dyno's system is their own system. I don't personally know anyone using it but have heard both good and bad reports about them in general. We found them good on our dyno day a few years back.

I'm guessing that the headers will probably be Pacemakers but that price sounds a bit high unless it's stainless steel or custom headers. Pacemakers are under $400, high flow cat $250ish, muffler $200ish. Usual labour rate is around $50 an hour so if it's a 6 hour install, then I guess it's okay.

I've also been quoted at a plugin computer from Redcliffe Dyno for $1690 installed and before and after dyno tuning.

Look on ebay and get a haltech or autronic and have them install and tune that, should still come in under $1690 and you will have a propper ECU, not a STD one with botched inputs.

With the extractors and exhaust, for 1200 make sure you are getting good quality extractors, mandrell bends, a nice muffler and a propper sized cat and flex piece. PACEMAKER extractors on the 3L's i have seen have mandrell bends :doubt: and although they do increase power when a good exhaust system is installed with them, im sure there is more to be made with a better designed set of headers. as for 1200, im not sure if thats good or bad but for a complete setup from engine to rear bumper its not the worst ive seen, just really find out what exactly your getting before you fork out the cash, write it down, then if there is any problems like they keep your std flex plat (making the whole system useless cos of 1 restriction) u can take it back and remind them what the quote was for

40-50kw even at the flywheel is a huge difference, i would be suspicious about any place that quoted that. For a car to gain that there would have to be either forced induction, open engine work or NOS involved.

Turbo Charade: You will find that a haltech is very expensive. A full programable stand alone ECU is very expensive to install and tune. You will find that it would cost about 3k to buy, install and tune.

I have CIA,HEADERS,EXHUAST and i doubt iv achieved near that...

ive bought 2 now, a brand new microtech is only around 1200 dollars. it really just depends if you install it yourself... ive got access to a AFR meter so it makes it pretty easy for me to install and basic tune a car just to get it over to get a propper tune done. 3K would be Maximum if you did no labour yourself.

bob romano does the unichip for 1500 in and out dyno inclusive they are at wynnum maybe ask them on the qld dyno day coz thats where they gonna hav it and with e manage i think vrx benno found some1 who can install them in gold coast coz he installed his last december last yr and yet im still tryin to chase him up for the cost of installation

Hmm... I was actually surprised that we're going there. I know of at least two members here who were either laughed at or asked why we would bother doing anything to a Magna.

That said, I'm looking forward to the day. Last time I priced an install and tune, it was $1250.

ha to make it faster than a bogan mobile commodore or falcon! oh and my skyline (damm they are already faster!)

not sure what state u live in but i have put extractors and new flexi pipe up to cat and have got 2 1/2 inc pipe running through 18in hot dog in middle if car then down to straight through stainless muffler and 3 in dump pipe just under rear bumper and also have had powerchip gold fitted to computer and the difference to the car is fantastic. Exhaust was done by street and strip exhaust dandenong, Total price for job was 1050 dollars and if you go into powerchip on the net you can find out more about what would suit your car hope this can help

Thanks for all the advice, I'm not gonna get a computer, due to the fact it changes the car so much, it's just gonna have a dyno tune to run on Optimax only with the exhauset instead. There is no real point in getting a computer for my car at the moment and apparently I'm gonna get the similar power increases from getting the orig computer remmaped istead, for less than half the price of a computer. Thank everybody

you'll need a computer (either full replacement or piggyback) to dyno tune the engine (and to tune to optimax or similar).

To my knowledge you cannot just tap into the existing ecu and 'tune' it. whoever says they can tune it is lying to you (unless someone can prove me wrong).

piggyback chips like unichip and emanage do just that - 'piggyback' the OEM ecu, so that all original electrical settings stay stock, the only thing they change is the fuelling,etc. for dyno tuning (+ for optimax).
