Possible Ideas for Cheap/Free kW...

[TJTime]

Hey guys,

I have built a magna with a 6G75 (Mitsu 380 motor, 3.8ltr), with a full exhaust system etc etc who gives a shit its just a magna etc....

Anyways, she makes about 165kW at the front wheels and I'm looking to squeeze the last few kW out before I possibly go cams. I'm not interested in Nitrous/Turbro/Zupahcharging either...

I was wondering if you guys had much in the way of expertise with:

1. Insulated Gaskets (intake manifold etc...)
2. Heated throttlebody (magna) that gets plugged up in order to cool the intake charge
3. Any other NA engine tricks/secrets you think would be good to share? Maybe buy a bellmouth and fit pre-MAF? I'm really fishing for ideas now.

Anyhoo, cheers.

Strip the back seats + boot - will actually have effects

[lysdexia]

those manifold spacer things are meant to make good gains on these engines i think

cool conversion btw

Lightweight aluminium flywheel.

Cheers boys! I'll just say, no change of engine mounts are needed at all for this conversion.

Been looking up lightened/underdriven crank pulleys. Worth it? Anybody here have first-hand experience with them? Any weird harmonics? Had a belt fly off? Had a crank pulley crack?

For the dollars spent, no.
Well not unless you can get a factory pulley (wreckers cheap) off something that will also fit your engine but is larger or smaller as you need it to be.

I know less than nothing about these engines so I will give you a reliable and predictable guide that you should take as Gospel*

Intake: If you havent done so already look into stuffing as much air into the motor as possible. See if the intake has any restrictions (filter inlet and piping change, throttle body upgrade, cold air induction/enclosed pod filter) which can be easily changed. Factory airboxes have to be good at getting air to the engine without creating too much inlet noise and usually have all sorts of resonators and bends to keep the noise down which restricts flow. Bin them and see if it makes a difference and go from there.

Manifold: Is there another manifold from another engine that can be bolted on for gains that has longer runners or a bigger plenum? I also seem to remember that the phenolic spacers make good gains on these cars, chuck some in if you can.

ECU: What is the stock management like? Good gains can be had by adjusting ignition and cam timing (if these engines even have MIVEC style setup?) so look into a stand alone or piggy back interceptor and see whats possible. Possibly aftermarket style adjustable cam gears as well? Might even be able to raise the rev limit a bit too (if the engine is still making power up high otherwise all you will gain is wank factor)

Gearing: What gearbox/diff is the car running? Is it possible to put a higher ratio diff in easily (eg, 3.45 final drive up to 4.11's)? It wont make any extra power as such but will certainly get you moving and make the car much quicker.

Add lightness: Depending on how keen you are start turfing unwanted shit. Every thing you rip out is less weight for the car to carry around.
Recommended for go fast, not recommended for daily drivers.

not sure if its the same engine - but supercrown ,on here, did some stuff with phenolic spacers on a 380 engine:

I know you are not keen on Zupahcharging but what about Supercharing?

this is burning of wood yea?

Also, try using lightweight synthetic oils and 98RON fuel

[myliberty]

Supercharing is what Jack Daniels does to their Barrels before filling them with sweet sweet Bourbon.

Imparts colour and flavour.

This is actually the most helpfull post here.

Stop touching your camry and have a bourbon.

[SausageFingers]

I would also like to subscribe to the idea of supercharing, are there any forums ?

[<---cop]

I'm not interested in Nitrous/Turbro/Zupahcharging either...

I am interested in acquiring one of those turbro devices.
How do they compare to supercharing which I can also afford?

[Sketchy]

Turbros are sweet as cuz. Not as cool as Zoopacharging (which is a more in depth scientific application of zupahcharing) but still sweet as ay.

[EVOSTi]

Good grippy tyres?

[GTV]

lightweight wheels

Zoopacharging is much better than zupahcharging but both are fairly old school now. Zoopahracharging is the new hotness!

Ha funny, everybody I've showed the car to says to chuck a blower/turbo on it and to be honest, I cbf'd spending $5-15k making a pretty fast magna already faster...

Fair enough I think. Also the 380 motor sounds pretty nice when reved hard in na form tbh. Would take some of that appeal from it. As you said its just a magna and traction will always be an issue with any decent amount of power.

The only thing I can really think of besides the intake spacers, would be an after market ecu and maybe a head shave to raise compression and e85. But that starts becoming a whole lot of work and a bit of coin. Not as much as zupacharging though.

[TJTime]

No need for an aftermarket ECU when you can use EcuFlash to change the tune. I'd be running dedicated e85 if there were enough servo's around...

[MexicanBatman]

been there done that, well not the 380 swap, but done the supercharging to a magna

without spending 15K thats about as fast as its going to go, you will lunch the engine if you boost it, as they take 6.5psi but that's gay why boost something to run fuck all boost, and any more and the pistons eat a dick

keep it as is and buy a car thats turbo to start with and play with that

Ran it yesterday on the same dyno, and it delivered a full 12kw more at the treads with the air duct and the spacers. We then swapped the small air duct back on it and it dropped just over 2 kw.

That means the spacers were good for 10kw!

Fair enough. You already have a flash?

E85 wont give you good gains unless you raise the compression. If you get to that stage, look into how much you can shave off the head before you run into problems. Might aswell do a valve grind while the head is off too.

But without e85 near you it doesn't matter i guess. There are a lot more out there now with the eflex.
