Hey guys

Looking to get a bit more Punch out of my car, what can you suggest in order to get this done without spending big $$$'s

Manual? SKR tune, full exhaust, CAI

Already Manual :) not really keen on getting the car up to qld for skr lol Already have a CAT back exhaust but guess i can look at having it extended.

CAI???

CAI = Cold air intake.

You've done about all you can do without spending big dollars.

SKR is in Adelaide, not Queensland.

A set of extractors would be your next step. Won't give huge gains, but I'd probably do that before I did anything else.

SKR is here, in adelaide....

Well thats even worse lol!!!!

Red what do you think id be looking at for a set of extractors?

550-600 for Pacemakers and chuck on another 150-200 for installation and custom Y pipe made

Pacies make a big difference IMO, you can feel the how responsive they make the car. Definitely worth the few hunge they cost. If you are lucky you can pick up a set cheap off AMC!

I've been toying with the idea of extractors myself... TJTime, is your car auto or manual, and have you done any exhaust mods bar the extractors?

Ben (TJTime) has a manual with full exhaust system - pacies, metal high flow cat, etc.
It's not exactly quiet lol, probably the loudest car in AMC NSW.

Lmao cheers dingers, now I have all of NSW highway patrol on my ass haha.

My car was 5sp auto when they were put on, without any other engine/exhaust work. With the tj2 sports exhaust, you could hear the extra grumble and I found it wanted to rev out faster with them on.

Now after I DIYed it manual, it feels like a dream. It's the fastest magna in the Campbelltown magna "crew" for now...

Thanks for that mate, that's just the answer I was after.

Did you change the Y-pipe on the Pacies too, or is that only advisable if you've upgraded the rest of your exhaust to something larger?

To save starting a new thread, does everyone get the same SKR postal tune? $250 seems like a bargain. Can anyone post before/after power and torque curves for a 3.5L manual, or some pessimistic (realistic) numbers you'd expect? Qualitatively does it provide more mid-range torque, high-end power etc?

250 or 350 cnt remmber... bought too many things got prices confused... But that was POSTAL tune not on dyno... :) n for a 6g75 in magna ...not the 74

But i hear great things from ppl with the 74 who get it tund after exhaust and they are always VERY happy wiht the tune i rekon slap some ralliart cams on it :) some thread about gaining 15% beta fuel and a load more of power :D

Yes I understand people are happy with the tune, but people here are also happy putting irrigation tubing in their engine bay and telling everyone how fast their cars go as a result. Are there any clear cut results you can refer me to?

Check out el3ment's Member's Machine thread, I know he has a 3.5 manual with a SKR tune... his was done in-person by Steve though.

Appreciated.

I can't provide you with dyno charts, but I can speak from personal experience.

I had a stock Ralliart magna, years ago now (about 5 years) I did a full 2.5" exhaust system, Pacemaker extractors, EZboy CAI (waste of money), and a Haltech Interceptor piggy back ECU tuned by Bob Romano in Brisbane. With those mods I made 195hpatw (145kwatw) There was a small gain in mid to top end power and a small gain in fuel economy.

At a QMD (Queensland Magna Division) dyno day, if memory serves me correctly, my car made 192hpatw (143kwatw). There were 2 stock Ralliarts there on the day belonging to Pete (QMDBOI) and Rick (Ralliart Rick) - Both of those cars made around 175hpatw (130kwatw) There was also a couple Executive models, correct me if I'm wrong here someone, belonging to Element, who at the time I believe had the same mods done to his car as mine did except for the tune. His car ended up doing about 182hpatw (135kwatw).

So, at the end of the day there are small gains to be had with a tune, but not much. For me, I spent $1700 on the chip and tune (plus fuel filter which needed to be done at the time) so it wasn't great bang for your buck. Having said that, if you do a full exhaust system and extractors, and can get a postal tune for $250 to pick up another 7kwatw or so, for a total gain of around 15-20kwatw, then it's probably worth it. All up for exhaust, extractors and postal tune you're probably looking at a bit over $2k for 15kwatw. From there it's your decision whether it's worth it or not.

CAI = Cold air intake.

You've done about all you can do without spending big dollars.

Lol i actually agree with disciple for a change :)

Extractors will move power a little but no real increase

Cai will make a cool sound, allow you to lock your engine up if you hit a puddle and that will mean 0 power as will be stuffed

SKR is really the only thing left for moderate increase and then the postal tune is only a guess


Thing is that power is not cheap or free. Others spend many thousands on cars made to get big power. Is time the mafna community alsonrealised that while we can get there a family car needs even more spent to get close

Thanks for that mate, that's just the answer I was after.

If you want headers imo the only ones worth it are hm as a lot of the others are really cheapies. The exforce are made out ofnfoil and i have replaced a few sets nownwhich have cracked. The pacemaker are not a complete bold on header and are known to crack at the header flange and hurricane tend to hit rhe floor. Rpw ones are just hurricane

Check my member machine thread
I have a full exhaust system, RPW CAI
and gave steve a visit for tune
B4 he changes anything, he'll get a dyno reading to compare it after he finish,
It did 134 fwkw and after the tune the final output was 143.7 fwkw, that's a good 10 kw just from the tune, n my car was 5 speed auto, then back to Mal, had a manual conversion done, and 380 cams put in, and I drove back to steve to had a retune done and the final output was 154 fwkw that's another 10 kw from manual and 380 cams

Bottom line. u need a noticeable power increase? U need the following

Full exhaust system Around ($1400)
CAI around ($350)
380 cams around ($300)
Manual around ($1600)
SKR dyno tune, not postal ($500)

That's just over 4K But ur car will look like a stock car

for the ppl going to argue about CAI is waste of money, well I didn't get extra power out of it, but the air temperature if the pod in the engine bay was 57 degrees with open bonnet then put it back where it was ( behind the fog light) and the air temp dropped to 21 degrees, never tested it with the stock box tho, so it's ur car and you decision.

Good luck

If my research is correct then 6G74 runs at the heart of its efficiency with the hardware thats installed. If you want to make it produce big power then you might as well spend big bucks if big power is your goal. You could drag it up to and a little above Ralliart Magna level and that will be about it. Next is either a 6G75 conversion, full build for big-power NA power, forced induction or combo of them. But remember that there is only so much you can put through the front wheels. That will make you concentrate on mid-range rather then bottom end (wheelspin is easily achieved with engine as it is) and top end. In any case if a decent chunk of power is what you are after you will not get it cheaply. Sorry to burst the bubble. Although Disciple and Mal already have done so lol
