Looking over the dyno thread they seem rather lackluster for a big 3.5L V6. 200 odd horsepower thats it?

I like my Verada enough to want to keep it for quite a long time and i'm tossing up the idea of whether or not I should start putting some cash into it. I've never bothered with cars, always been into bikes. In stock trim the engine seems pretty punchy off the line, and while it wants to get going between 3000 to 5000rpm, still seems like its very restricted. Yet the dyno numbers being posted seem rather.... sad to be honest. I was expecting 500hp+ by at least a few people

I wouldn't want to go overboard. I'd like to keep the stock exhaust, or at least something thats near whisper quiet when cruising and not obnoxiously loud. Maintain reliability and as good if not better fuel economy when cruising.
It just seems silly that some of the highest figures barely push 200hp at the wheels, when plenty of 2.0L V4's are pumping out over twice that with a bit of a kick in the pants
So, are these engines worth tuning up? or keep it stock and simple?

how deep is your pocket?
feel free to aim for 600+

Firstly - I can vouch for a few 450 hp atw cars on here and they've put alot of money into their cars because they love their cars.

You're cars performance is only limited to how deep your pockets are, im sure you have seen alot of stupidly fast bikes out there too being a fan of them as you say.

In the end its a 10 - 20 year old car depending on your year model and a sohc v6 is only going to get you so far performance wise.

But a third gen magna/verada has something the 2nd gen doesn't have and that's a bolt on supercharger kit.

So theres a start there if you want a kick in the guts as you put it.

3rd gens are tuned quite well from factory. An ECU reflash will see gains but nothing massive. Best bang for buck are a free flow muffler, manual conversion or 6G75 conversion.

There is one member (EGO) who has cracked 500hp. You make it sound like there's nothing to it but that couldn't be further from the truth. Aftermarket support for Magnas is limited at best - parts all have to be custom made, which makes an already expensive exercise even more costly. You don't have the range of parts or installers that you have on, say, a Commodore or an import.

Even if you can get that kind of power going in the engine, you have to get it to the ground somehow. I'm pretty sure Jase has had a lot of issues with CVs, clutches etc in his nugget and he isn't even running full power daily. Plus, you are always going to have major traction issues no matter what you do.

A worked Magna is unique but if you just want to go fast, there are far better cars for it imo.

Found a couple of contradictions in the op's first post.
He wants to make more "HP" (= Kw, I think he means) at more RPM but wants to do it with the standard exhaust, while maintaining reliability and improve cruising fuel economy. Without "going overboard" as well, I assume he means "cheaply".

Harry Potter, where are you? We need to borrow your magic wand! lol

As for the 2.0L V4s that reportedly make 400 + HP (or 300 + Kw), ask the owners to show you the parts lists they used, the cost, how reliable they are in daily use, and the DYNO SHEETS.

Call me cynical, but I smell a troll. If not trolling, do some research into what can be done, and go for it.

getting major horsepower gains takes a lot of money, dosent matter what car it is, take the good old commodore, they boast that simply changing the fuel chip will give you extra power, what they dont tell you is for a couple of hundred dollars in changing that chip only gives around 15kw extra power. the magna is pretty resilient, throw a 3.0l manual in, ralliart cams, rpw performance manifold, and an ecu re-flash, HM headers, 2 1/2 exhaust for a start, and you will be surprised what sort of gains you can get (thats my setup anyway).

I'd do 380 cams on the 3.5 over a tune.

paint your brake callipers red or black for a 25KW gain.

From my understanding the internals are not as durable as your average import - therefore your having to shell out for pistons and rods at a lower power level.

However I am interested in these supercharger kits mentioned, someone have a link?

Red is 25, I think black is only 20 IIRC? Orange is more like 22, by my butt-o-meter. lol

Seriously . . . OP hasn't come back to this thread, perhaps he was only fishing for a reaction from you guys? lol

If you look at cars of similar era to your 6g74 you would be surprised.

For eg the hsv XU-6, supercharged it made 180kw(@ the flywheel I believe?). Same power as the n/a magna ralliart, only the xu6 is slower.
Or the group A's and hsv commodores of the 90's with the loval 4.9 lt v8, 195kw was about the highest I think they got back then.

Remember these were cars modified by hsv, above factory spec.

Golf GTI for instance, stock it puts out almost as much power as the 6G74, granted it has a turbo but the magna/verada engine is almost twice as big to begin with. It's not too much of a stretch to pull 300hp out of a golf GTI but from what i've seen it is a big stretch to gain anywhere near that with the 6G74. Even the 'bolt on supercharger' is barely pushing past 200hp at the wheels :S

Compare apples with apples. The GTi engine benefits from newer technology, more advanced materials and engineering. The engine is specifically designed for a turbo application from factory, of course its going to produce decent figures.
The 6G74 has been around since 1992 (introduced in the Japanese 3rd generation Debonair), not originally destined for forced induction (in 6G74 form anyway); and the basic 6G7# design has been around since the 1986.

I think that little lecture about history will be lost on millenium7, if a 2014 Golf engine can make a billion HP, then a 30 year old Mitsu design should as well.

Of course, VW once made a 1.1L that put out 36 HP, then entered the performance car market with a 1.2L 40 HP engine!

History . . . . learn from it.

Compare the GTi engine to a comparable Mitsu one instead. EVO?

Evo = 217 Kw 2.0L
GTi = 169 Kw, 2.0L

The engine is also in a family sedan, where top end power is less important than mid/ow range power for everyday use.
Since these engines rev fairly high, if you got peak power at 6,500rpm you'd also be making well over 200kw.
The JDM models came with 200kw engines

"Do these cars respond well to tuning?"

Definitive answer: No they don't, unless you have plenty of time, money and effort to spare. It is a well designed 1980's engine made with low to mid range power and reliability in mind.
Not a race car engine.

Go buy a Golf or Evo if you are not happy driving one.

Tbh dude if you want cheap power. Go buy a falcon or a commodore. There large family sedans that respond very well to tuning. From what I see in this thread I believe that's what your after.
