If one wanted to push an extra 20-30kw's out of one's car how and what would one install to accomplish this???

a 380 motor will do this if not a little more

and whats that likely to set me back???

unsure on the price as i havent done it yet!

Mine cost me $700, and all up including fluids, timing belt kit etc... has costed me about $1100. Ask any of the ctown crew guys here and they'll tell you how it pulls! If you are planning to do one, I'll be happy to help :D

hang on r u saying $700 or $1100 cuz they are very different prices on my salary

hang on r u saying $700 or $1100 cuz they are very different prices on my salary

Are you serious? The motor cost me $700! The other stuff I needed for the conversion cost me $400! I could have done it for about $950, if I didnt waste money getting another motor (which had a rusted out water pipe and other crap) to sit in my backyard.

$700 isnt much. Its actually less than what I've spent on engine oil and engine oil filters on my car over the 80 thousand k's I've owned her for

no im not saying $700 is heaps thats fine i can deal with $1000 as well im really just after like a total costing, and any help would be massivly appreciated.

Just trade your VRX in for a Aurion instant 20-30 KWs just there

$700 for a motor is a bloody good price and Ben was able to swap it out himself.

Unless you are in the mechanic trade don't expect to have a 380 engine fitted and running in your engine bay for $1000 lol

Probably more time without a licence.


Licence Suspended

With any car mods, you have to accommodate for extra costs. Why not budget $1500 if you are going to DIY, or $2k+ if you are going to pay somebody to do it...

Anyway, 380 motors are getting expensive as people are buying and selling them for a profit. I havent seen or heard of a 380 motor going for less than $1.5k anyway....

Ralliart engine is another choice. Easy 17kw, send it to SKR for a 20kwish gain.

Not cheap, though.

yeah for the price of a ralliart engine + tune + install you could probably get some better installed cams and make as much power and still have the money left for the skr tune.
that's just from looking at how much people try to get for ralliart engines.

If you are running stock brakes, you need to upgrade to something beefier before chucking in a more powerful engine is my advice. Also, sort the suspension out if you havent already.

He wants to keep his car dude, not trade it in for a boat

$700 for a 380 engine is very cheap, when I did a big ring around many were happy to sell me one for the $800 mark, found 3, all of which were from flooded cars with no warranty or even idea of mileage as the odo were not working on the cars due to the flood damage, others told me around $900 but they dont have any so no real use in quoting if you can not supply

These engines have always been higher in price, as for selling for a profit, last time I looked that is how business works, you make profit to then pay for lease, insurance, wages, equipment etc etc. I know that for a long time the average price has been between $1500 and $2000, in SA the cabs still use 380's and other places the cars go on average for $2000 to $3500 so in order to make any money from a car the engine has to be at least $1500 after all there is no market for the transmissions at the moment and when a car is in an accident a lot of the useable parts are damaged and can not be sold

If you want to gain 20 - 30kw, you need to spend money, KW = $$ and it seems that many Magna owners these days think that because the car is cheap that you can get good power from a pocket money allowance, this is not hte case if you want to do this properly.

What are you hoping to achieve from the extra 20-30? Is it only a figure you're after, or are you after a more driveable car? I suppose I'm wondering what you expect to gain from that extra power... and how it will improve what you aready have.

I wasn't trying to take a dig at you Mal, I was just saying that I've found the price of wrecks and motors to have jumped up in price in NSW over the last few months from increased demand from wreckers. Nothing wrong with selling anything for a profit.

50hp NOS kit ??? :)

50hp NOS kit ??? :)

exactly what i was thinking, bigger fuel pump and your away.

50hp NOS kit ??? :)

That's probably the cheapest and easiest way to do it. ~$900 for a dry kit, and you can fit the thing in a few hours...

can anybody give me a complete list of everything that would be required te succesfuly do an engine swap??

keeping in mind iv found a decent 380 engine with 54,000 on it.

Search for some posts on the subject by MadMagna (Mal) - he listed a lot (but not all) of the steps. To me the result sounds more like a 3.8L 3rd gen engine rather than a 380 engine based on the number of components that are retained from the 3.5 :)

If I was doing this, I'd be tempted to get Mal to do it - either have him build it and crate it up to Sydney or send/take my car down for the swap. I guess if I drove down I'd have to scoot over to SKR for a tune as well for the killer road trip combo. haha

I think its just the block, sump and heads from the 380 that go in, and some exhausts/extractors don't clear the 380 sump so it will either have to be modified, or different extractors used. Since the sump thing was worded as modification and not "swap from 3.5" im guessing something doesnt line up or fit between the 3.5 and 3.8, or the oil pickup might be a different length, not sure if the pickup is swappable.

Well a 3.5l with exhaust and 380 cam and tune will make around 150kwatw. Ive seen 2 magnas with 380 engines pull around the 150kwatw mark. So really with a 380 swap on your Vrx manual will be 20kwatw gain with the cost of doing so around 3 plus grand. 380 cam and tune roughly the late 1grand mark on the 3.5l. Plus im guessing the 380 will have more torque but theres traction issues were u wont have a problem in the 3.5l. But once u mod the 380 it will def make more power then the 3.5l but its all money factor

i mean if any1 has any other suggestions to get that sort of a power boost out of my car (minus boosting it) im open to suggestions.

380 Cams
SKR Tune
Extractors & Exhaust

And you be coming close to the 20kW mark.. But then again, factoring in the costs there.. You might as well visit Mal and have him jig up a 6G75 and drop that in..

SuFz

Nos is illegal on the street, and I assume you want the extra power on the street as well?

If you want 20kw (or close to that) and you're happy with that long-term then fit 380 cams, exhaust and proper flash/tune, as Kurt says for around 145-155kw @ wheels with a manual box.

If you are going to want closer to 30kw or more in the future (without boost) then the 380 engine will allow more scope, but the initial spend will be double or more.


I went the 380 option a couple months ago and got a power run on the dyno out of interest. Without a proper matched tune it pushed out 159.7kw @ wheels. I guess a proper tune might add another 10kw.

So if your manual VRX makes 130-135kw @ wheels now (which I think most VRX's do), then you can see that option 1 is closer to your 20kw gain, option 2 is around the 30kw gain.

Just get the 380 motor... There are cams on the way for 6g75's that make a very streetable 190fwkW :D

So are alot of things, even an un-engineered 380 motor conversion. lol

I'm interested but wary.

I keep hearing rumours about these magical 380 cams but nothing concrete.

Any connection to AlanJ and his mate Graham who were working on uprated 380 cams a year or so ago but then everything went quiet?

Or is someone else working on them?

And what else is needed besides the cams to achieve 190fwkw?

I already have a manual transmission and a few intake and exhaust mods so with any luck I don't need anything else.

Or are we talking forged pistons, stronger valve springs etc?

KJ.

No i wouldn't i have one of these at work its a drive car i use everyday and you know what i think it sucks. :) or maybe its just me

Very true, i guess people think that if it looks like a 3.5 then no one will be any wiser. Nos is definate value for money, just set it up and put the tank in when you take it to the drags because it illegal to race on the street.

From the research I've done, a 380 engine conversion (at least in NSW) where you go from a 3rd gen magna, which had a maximum engine size of 3.5 lt, going to a 3.8 engine falls within the 15% allowance for increase in capacity for an engine swap.
If you are within this 15% limit and the swap needed no structural modifications, then you shouldn't need an engineers certificate.
It should fall under an 'owner certified' modification. Of course you have to notify the RTA of the change though.

NOS is great for the strip, but once you go to the street the main problems with a NOS system is as soon as you pop the bonnet it is very visible to see, and the fines are pretty high.
You can try for a stealth system but there is always a giveaway if you look hard enough, and they tend to be a bit comprimised by design.

Even if the 3.8 was illegal, to spot the difference between a 3.5 and 3.8 engine in the bay is much more difficult, especially if you leave the stock air intake etc.

Until of course you have a serious accident and the cops take it for inspection - find its modified without informing roads authority and insurance company void your insurance and lands you in the deepest shit

Agreed. The bit I had above in bold is the main bit, if you do this you're right, and for an owner certified mod, as long as the rest of the car is also legal as well, then changing the details with the RTA is not hard or costly.

Not naming any names until he wants to be known, this isn't Alan J either. I want the cam first though hahaha...
They are finishing development soonish as I am told and have been in development for quite some time. I think just standard motor, unsure of cam springs...

Why can't the cams fit in a 3.5L then as they have same cams to a magna?

not the valve springs though. The Ralliart had uprated these to increase tolerences with advanced cam

There are a few cam options for the 3.5, but you can't go too wild due to the lower CR. Value springs aren't an issue, they are $270 delivered for HD springs.

I just got my car up on a dyno and she made 157fwKW on a ralliart tune, so I'm happy. I think I need to get a walboro fuel pump after I get a postal tune cos she leans out a fair bit up top. Expecting 165kW+ with the tune and more with the modified 380 intake
