So i got myself a Gtech fanatic on friday (heard good reviews about them) and decided to try my quarter mile times and 0-100 times.
My car is a 2003 TJ Magna Sports 120000kms on the clock
Mods: Full exhaust by redback, streetfighter manifold and i run 98 ron

My best 0-100 time was 7.33 and my quarter mile time was 15.23 @ 146.3km
the road had a slight uphill of 0.6m

Anyway according to Mitsubishi my magna is supposed to do 0-100 in 7,04 was that just wish full thinking ? I understand that my car is now 9yrs old so it wouldnt perform aswell as brand new but i would have thought my minor mods would have evened that out again? Do my times sound right or am i doing something wrong?
I also realised that i got my best times with traction control off and tiptronic mode changing gears around 6.2 thousand revs

The 0-100 time of 7.04 was with a MANUAL gearbox and while the 5sp auto is much faster than the 4sp auto, it still is slower than the 5sp manual and always will be. In any car, 99 times out of a 100 a manual will always be quicker unless the auto is advanced and has lighting quick shifts like a DSG gearbox, which the magna does not have. Sometimes you just cannot beat having access to a clutch.

Even for a stock unmodified manual, getting a 0-100 time of 7.04 is difficult. The shifts need to be very quick and there's no room for error. So far, my best time with a 3.5L engine & a 3L manual box (shorter 1st & 2nd ratio = more power on launch) for the 0-100 sprint is 7.1 seconds.

Your time of 7.3 seconds is actually very good. You do have to consider that the car is almost 10 years old and is worn since factory. You've got around 120,000km and that is still a good amount of wear compared to how the car was when it rolled off the line so you can't really expect the car to have similar power to when it was manufactured. Mate of mine works for as a engine workshop and you'd be surprised how fast engines can loose power. I doubt there are many stock unmodified vrx/sports that could get that time. Your mods wouldn't really add much measureable power - unless the exhaust has headers then you're only likely to gain, at best, 2-3kw over the stock sports setup, the streetfighter manifold might do the same, and the 98RON well that will do nothing to power because the car doesn't know the difference between 91RON or 98RON.

Take off the street fighter and you may find a better time, the way these are made simply does not suit the Magna motor

Agreed. If you need proof of this, all of the IPRA class Magnas run the factory intake manifold.

Like MagnaPI said, the 7.04 is for a manual, not an auto. I have a Motor scan at home of a tiptronic VR-X and it was 7.75 sec for 0-100. I can't remember the quarter mile time but I believe it was a high 15. So your times are quite good.

It should be noted that your modifications will do virtually nothing for performance. Sports Magnas already have a ~2.4-2.5" exhaust and a straight-through rear muffler, so there's no real gains in changing it. 98 will also do very little (if anything) for performance because Magnas do not have a knock sensor, and cannot directly take advantage of the higher octane fuel.

For what it's worth, most aftermarket wheel and tyre packages come with pretty crappy rubber - so that might be holding you back a bit too. Getting traction off the line is certainly an issue.

Does the non-sports models have the same size piping? I was under the impression, that exhaust wise, the only difference between a sports/vrx/gtv(i) or a exec/advance/solara etc was just the muffler.

Also - definitely agree with the above on the streetfighter intake. Even members on here who run forced induction systems use the factory intake plenum. People sometimes forget that manufacturers spend a lot of time, money and research into getting their air intake systems right. Unless the manufacturer has made a more powerful and better intake system for your engine in a different model, then you can be quite certain, that in most circumstances, the best air intake system apart from a F/I setup is the manufacturer setup. This has been proven time and time again - especially with things like POD or panel filters that do SFA.

Yeah, the non-sports models have the same size piping. I was just saying that since the sports models have the free-flow muffler, there's not really any gains to be had at all.

Agreed - thanks :thumbsup: - it's amazing how restrictive the stock muffler is!

The only way to improve the stock sports system, is to fit a high flowing cat (200cpi is lowest legally you can go) and headers. Even this will likely only give about 4-5 tractable kilowatts. Exhaust matters much more when the car is inducted. Good headers cost min $600 and can noticeably improve responsiveness of the engine. The ralliart exhaust system is probably the best you can do with the magna engines to extract the max power from them before you plough them with forced induction or start upping the internals.

As others said 7.3 with an auto is pretty good I reckon.

Ah k interesting if I had originally known that the manual version is quicker I would have bought one of them when I wrote full exhaust I meant extractors and highflow cat that's why is was hoping to equal the 7 second time interesting that u guys say the manifold isn't any good iv read posts where people swear by it on the magna forums I did half drag a guy called norby he beat me in his tj vrx which was a manual I might swapmy manifold and test those times :) thanks guys

interesting that u guys say the manifold isn't any good iv read posts where people swear by it on the magna forums
The only people who swear by it are the people who made it lol


I did half drag a guy called norby he beat me in his tj vrx which was a manual
Are you talking about his black VR-X or his current white TJ? Because his white one is far from standard....

Extractors improve driveability but they don't do a whole lot for peak power on Magnas.

Only NA 6G74 auto that's cracked a 14 sec quarter mile was Magtone. Afaik he had RPW manifold, stage 1 cams, full exhaust, CAI, piggyback ECU and tune.

if I had originally known that the manual version is quicker

As a general rule - 99% of the time a manual gearbox will always be quicker than an auto, unless you're talking full scale drag racing (i.e. drag cars doing 6-7 second 1/4 mile passes). Up until the recent invention of DSG and other fancy auto gearboxes, manual was king. Even with DSG gearboxes, only a handful of car's are quicker in auto than manual. You just can't beat having no torque converter and having access & control of the clutch. Computers are one thing, pure raw power to the ground is anouther. If you're really serious with wanting the absolute quickest time then maybe consider doing a manual conversion. I did and I absolutely love it. The power difference is astounding. However this is coming from a 4sp auto. The difference between a 5sp auto and 5sp manual isn't massive (obviously more fun though) so it can be hard to justify the cost.

Even so, a full exhaust setup doesn't do much for a NA engine. The difference is noticeable in terms of responsiveness but the actual tractable difference is not very measurable. You'd be lucky to gain 5kw at the wheels from a full system.

If it's his white sports, as Red Valdez said, you don't have a hope in hell to beat it no matter what you do because that is probably one of the fastest N/A 6G74's in Australia. It's been bored out and done serious modifications to get 190kw at the wheels.

Close but not quite, Rob (Mr_roberto) who was one of those that got it in the group buy still has his and is still running it. from memory he said there was some kind of improvement there.
most everyone else however :P

Thanks for that magna pi and red valdez. When I first bought my magna I knew as good as nothing about them really wish I had gotten a ralliart magna back then now all of them have way to high ks. I don't think its worth a manual conversion if then is rather install a 6G75 engine shame it takes so long iv been looking at the fg xr6s their auto gearbox from Germany is quicker then the manual if only someonw independently tested this streetfighter manifold stormie when I dragged norby can't remember his car colour but norby was his number plate

Just remember factory quotes 0-100 figures are done by professionals and even then may be timed incorrectly. The 0-100 for ralliart magna manual stock is 6.7. I think i can only get 6.7 now after many mods.

Oh really how many mods have u done to Ur car not all companies are like for example BMW under quotes its m cars by almost half a second

My mods include upgraded suspension and wheel/tyre and also about 10kw engine power

You forgot the driver...

No offence :P I'm a crap driver as well haha

A tj 5sp auto will easily crack high 14 second quater mile. With 380 cams and a tune. There's not many people that have been to the quater with 5sp autos. My th sports did consistant 0-100 in 6.5 second with just a sports muffler.

Pwoah I seriously dout that Ur TH even got close to 7with one mod was that downhill?

Why would I do a 0-100 down a hill? Is that an accurate 0-100 NO. 0-100 in 6.5 seconds. My cars a manual. Hell I've done 0-100 in 3.0l manuals in 7 secs flat. If u can drive these cars to there limit they'll be capable of these times I guarantee u.

did another few runs just then improved my times a lil bit got a 7.29seconds to a hundred and 15.22 quarter mile. That was a perfect take off but so i dont think my magna could do any better then that

Put your stock manifold on and get some 380 cams witch I have a pair if u won't them and you'll crack 15 flat and 7 seconds flat. 380 cams improved my quater mile by .4 of a second no shit.

Guys, enough of the illegal street drag discussion please, we are very strict on these forums about this behavour

Dunno about everyone else but ever one of the cars I listed pulled up beside me at the drags :)

There's this thread that discussed 0-100 runs - here (http://www.aussiemagna.com/forums/showthread.php?t=67736&pagenumber=)


Guys, enough of the illegal street drag discussion please, we are very strict on these forums about this behavour

Agreed. 0-100 maybe, in the right spot, but the old quarter mile runs on public roads? A bit risky.

I did a few 0-100 runs and uploaded the Evoscan graphs to the thread linked above if you're interested.

Thanks Kurt but I think I'm going to buy the fg xr6 later this year oh and mad magna I tried these quarter mile times on my uncle's farm xD
