i am starting to think about what to change to get more power from my car.

So if anyone wants to help i was thinking, if you post what you did then cost(around abouts) and kw's gained.

i am thinking that in the long run it may be better to save up for a supercharger.
so help would be good. :)

by far the best bang for your buck mod is a supercharger by sprintex

all other mods do sweet f a compared to how much they cost

just repeating what ive heard but for power gained i thougth turbo was cheaper and better power??

(please not question marks notating this as a curious question before tearing new rear)

The Sprintex kit mentioned above (only suitable for 3.5L remember) is worth between $7,500 and $8,500 (ballpark figures) once it's been isntalled, it is true that this is significantly cheaper than the RPW twin turbo kits.

However, from all accounts - the sprintex kit will take a 3.5L magna to approx 220kW (thats what they quote from memory), but is unable to be modified, ie: cannot increase boost etc. A well planned turbo build up will probably be able to produce similar power in a "stage 1" configuration, with the bonus of being able to squeeze more power out of it as funding allows.

Either way - forced induction seems like a huge step to someone yet to spend any money on modding their magna, however - most of us who have tried to get good N/A power out of these cars will now agree that going straight to boost of some sort would be cheaper in the long run.

As for best bang for your buck.......... I'm gonna say it might just be NOS.

apparantely the later kits are rated at 230-240kw.

Seeing as on the RPW pricing PDF file it says the "Stage 1" turbo kit is good for 220kW. Being that that figure would be taken from a standard 3.5L Magna engine @ 150kW (roughly) that's a 70kW increase making 220kW. Would it be fair to assume that adding that kit to a Ralliart, which already has 180kW, that a Ralliart could potentially be in the vecinity of 250kW?

Would it be fair to assume that adding that kit to a Ralliart, which already has 180kW, that a Ralliart could potentially be in the vecinity of 250kW?

Unfortunately - I'd have to say probably not. While a stock ralliart might produce higher output than a stock exec with the addition of a stage 1 turbo kit - I don't think it would be the full 30kW difference between the two engines standard.

The main reason for this is that the Ralliart engine got a higher compression ratio than the standard engine, as well as a cam profile designed for better N/A power. Both of these differences are not conducive to better 'boosted' power. Infact you might find that a ralliart engine needs to have decompressed head gaskets fitted before it can safely run the same boost as the RPW 'stage1' kit delivers.

I could be wrong however......

Be sure you are all comparing the same power figures, are we talking power figures at the wheels e.g. front-wheel kilo-watts or power at the engine/flywheel ???

From memory I recall sprintex power figures being at the engine and rpw's being at the wheels???

im thinking that becuase the S/C will not go from no boost to on boost that will make the car much more drivable,

"Sprintex installed a Superhcarger Kit to this Magna VRX FWD with outstanding results. Achieving post Supercharger figures of 251 kW and 440 NM, this Magna benefited from extra modifications, including a custom dual exhaust system and port and polished heads."

"225 kW of power and 422 NM of torque provide the Mitsubishi Magna VRX AWD with a new dimension in performance. The seductive howl of the Supercharger lets you know this is no ordinary Magna and only enhances the fine balance of handling and grip from the AWD chassis."

The supercharger is worth every cent. I am yet to have it dyno'ed, waiting til i get extractors on. Sprintex has advised that I should be lookingat 235 to 240kw at the fly. This almost being an additional 50% power. It isnt a race car, but hell it is one quick family car. I can tell you there have been a lot of very surpised Skyline, WRX, XR6T and V8's out there. The added benefit compared to turbo is the CONSTANT power no lag whatsoever. 1500rpm onwards and the power is there. Realistically with gains of 45-50% the only other mods you NEED is lowering and brakes. all other mods, extractors exhaust etc off minor gains if any, and the cost doesnt compare. ie extractor $660 plus $200 fitting for 4-6 kw?
And it does all this at just 7-8psi. No need to stuff around witht he internals like you would if you put it up to 12-15psi.

Honestly if you are expect good follow up service and a reliable long term product, go the supercharger. Having had a turbo 4wd i can tell you 50000k and u r looking at replacing seals etc, for the supercharger $100 for a belt.

A couple of things to remember. The Sprintex kits are legal, ADR compliant and emissions compliant. They will however need an engineers report before you can legally register it. You will need to be legally registered before you can insure it. The same is probably true for the RPW TT kits, but I'm not sure.

More important than outright kilowatts, is power delivery and torque. You want it to be early in the rev range and constant in delivery.


.

I got quoted $12,500 for a stage 1 twin turbo kit from RPW

Turbo setups are misleadingly expensive.

that 12,500 included EVERYTHING but, labour, ecu, dyno tuning, an engine rebuild with strenghened internals etc.

Its a real shame that Sprintex doesn't do SC kits for the 3.0L engines or itd be something I would look at.

I am yet to have it dyno'ed, waiting til i get extractors on. Sprintex has advised that I should be lookingat 235 to 240kw at the fly.

Can this be taken to mean Sprintex don't tune the car on a dyno? Surely they don't use a one size fits all approach with their kit?

Hey Pete !

Just before you go spending your hard earned dollars on your ride please read this...

I see by your profile you have a 3.5 ltr manual front wheel drive magna !

Do you have a LSD or taction control ?

I tell you for why !

Wether supercharger or turbo the problem you are going to have is front wheel traction !

My 1998 3.0ltr yes 3.0ltr auto "NON" LSD and "Non" traction control magna !

Unichip:
$1,420 fitted
Extractors, high flow "steel cat" 2.5" staight thru exhaust with hot dog type center mufler and straight thru large rear stainless Mufler
$1,440 fitted
K&N Pannel filter
$.... dont know got it for a swap on a job i did for him !
Lowered all round:
$440
Strut brace
$200
Sway bars front and rear fitted
$600
17' sticky tyres on the front at $300 each
$600
Brake upgrade
$800

TOTAL
$5,000 plus some change !

But my problem is wheel spin... wheel spin... wheel spin... and I mean smoke the tyres wheel spin in a left turn and it doesnt stop smoking till it changes thru into second.

I do alot of autoKanahs and the clasic challenge (bit like taga but lower key here in Perth)
and when your in a left or right turn and give it stick it really looses traction and your on and off the gas pedal trying to get traction (wet weather is utterly hopless always on the hand brake to turn the car in the right direction)!

I run against integras skylines toyotas BMW's comodors and falcons !

In a straight line in the dry its great as you have equal preasure on both tyres but on a turn type track exceleration wheel spin is a bugger at best !

When ever your loosing traction your loosing time !

In a straight line drag race I leave for dead the toyota 3ltr V6
the Honda V6 integra over 400 meters Im over a car length on him !

Davs magna does an 11 second 1/4 mile which is fine but I have traction trouble in my 3ltr on the short twisting circut !

Im doing the babagello race way meet next month so I will see how mine goes on the more open track with wider sweaping turns !

If I had my time over again I would find an AWD 3.5 ltr and put on a super charger !

The super charger is $7,500 fitted at sprintex and develops 240kw in the AWD auto

The all wheel drives are autos but the rallyart is in manual !

As I under stand with turbos you should beaf up the internals of the motor and are a fair bit more expensive then a super charger !

The supercharger however doesnt require the internal beefing up because it doesnt develope that... "sheer neck breaking horse power" of the turbo/s but being mechanical driven the super charger lacks that initial lower end torque but is more usable as power increases right across the power / rev range !

If all you read is wheel spin wheel spin wheel spin and it stops and causes you to think then you have my best advise from some one that has tricked the 3ltr magna with enough boltons and drives the magna competitivly to know what he is talking about !

Rallyart AWD 3.5 ltr manual or AWD auto with supercharger is the go I would say !

One other thought... maybe if you looked at what you want your ride to do and just maybe a front wheel drive magna is not what your really after !

Ps. contry to popular beleif the unichip is not woth the money I spent on it !
And thank you (not) to the peole that recomended it !
There are far better options !

yeah it sounds alight, i suppose-for a bulldogs car:bowrofl:
the benifits are even more in a FWD compared to an AWD in straight line performance and also your car is manual so even more improvement there

Traction is always going to be a problem in front wheel drives see my post above

Can this be taken to mean Sprintex don't tune the car on a dyno? Surely they don't use a one size fits all approach with their kit?

No they definately use a dyno, they've used our dyno(unfortunately not for a magna yet), what that will be is their educated guess seeing as they do this for a living and have been doing it for years. I could tell you exactly(within 1,2kw) how much I will get out of your toyota landcruiser when I fit a turbo to it :) because I've done dozens.

Matthius

P.S: Needabettercar - most people on the forums would reccomend a Greddy emanage or haltech before a unichip from what I've seen.

Nice one, Nic, except there is no Ralliart AWD, and a supercharger DOES give you low down response when compared with a turbo because a turbo needs exhaust gas volume and velocity to spin its compressor wheel, which you don't get at low rpm.

I appreciate what you're saying, however having seen markedly different AFR curves on my magna compared to others on the forum, there are potentially substantial differences that need to be accounted for.

Maybe I'm paranoid, but I'd be concerned to have a massive change to my engine's behaviour made and not at least check that everything is within spec. Granted you don't need a dyno to check mixtures..

Hey cthulhu !

Is that the best you can do ?

Picked 2 imiterial things from my entire post !

I see you have a 3.5 ltr sports so I am asuming you have a LSD fitted !

You also have an extensive amount of RPW accesories and a greedy piggyback as well which RPW recomend !

Tell me something... Pete asked for advise on his ride which i gave as he has a non LSD magna like mine !

The 2 trivial things you mentioned, what has that got to do with what I said about traction and the real question Pete asked on his ride ?

Please stick to the subject matter at hand

Dude, I was correcting errors in your posted information, not attacking you.

No, the 3.5L sports doesn't have an LSD from the factory, and I haven't had one fitted subsequently.

I also installed a Haltech Interceptor, not a Greddy E-Manage. I've since replaced that with a Haltech E6X, and quite a number of non RPW mods.

Good for you cthulhu !

And now the thread has degenerated into a he said she said debate taking this thread further away fron what Pete was asking and my "on subject" response !

So without further to do I wont be responding to this thread any further !

You do that. Wheel spin is always going to be a factor, be it FWD or RWD.

hey this post went on for a while, i didn't see any of this stuff, thats for you help all. and maybe i should have added in my profile that i do have a ralliart and so i also have an LSD. but, i have kinda worked out i will save for one. but not to quickly just put some money away every now and then.
