Dos and Don'ts for New Turbo Owner - HELP NEEDED!

[ShallowRiver]

acbc...
no modification actually... all i need to know is i just wanna know if these gadgets will help to know what's wrong with my car and so i can take care of it... the last is someone comes and tell me that i need a hell lotta money to get it fix (i drove an alfa before, so, it's a nightmare). The warranty runs out like in 3 years. lol

 

[ShallowRiver]

yeah... removing the speed cut, fluffy.

 

[Fluffy]

well,if u didnt touch the car,no mods or watsoever..dont worry.everything should be fine.quite unlikely something REAL bad would happen.

 

[ShallowRiver]

fluffy,
RSM = removing seed cut?

 

[Adeen]

supposedly.....the RSM does remove the speed cut for most cars....

A turbo charged engine can get increase in hp quite easily, if thats what you're into..

 

[ShallowRiver]

Well... I am not looking into increasing the hp as of yet... Now I just wanna know how and what I can do to take of the car better and understand it more... before I start considering my options...

 

[E3newbie]

Basically it's the same maintainence as all other engines, just that it's better to let the turbo cool/spool down but thats been discussed ya? To get better understanding i suggest you read some treads in the Tech: forced induction section. Very informative..:)

 

[ShallowRiver]

and also should i install an afc and a boost meter?

 

[E3newbie]

The function of a boost meter is to read your current boost preasure. If you're not gonna up the boost, its not a nessesity. AFC, not if you want to keep it stock. Since it's a new car keep it stock till you're bored of it and want a little more, theres plenty to tap on when the time comes..:)

 

[hani]

how long or how far can we boost on the turbo, assuming our turbo is stock and cruising at a highway?

is theres any limitation or whatsoever for turbo cars?

 

[E3newbie]

If you're at crusing speed, Your trrbo shouldn't be spooling very hard. No problems there. Turbo spools up when you are accelarating or at high/top speed.

 

[ShallowRiver]

actually, i have yet to feel the myth of a mivec turbo. hahahaha
still drive mine like a normal car...

anyone car to try it out with me?

 

[acbc]

For stock car, u don't need any gauges unless u want to increase the power later. When u do increase power, u need to rebuild the stock auto gearbox because all Mitsu cars have very weak auto gearbox.

But, for the fun of it, a boost gauge is quite useful.

 

[ShallowRiver]

acbc,
even with the new cvt transmission gear box?
and what do u mean rebuild the stock gear box?

 

[acbc]

Yes, the auto gearbox (CVT included) is very weak and not suitable for high power application in stock form. U need to rebuild it with stronger parts. A typical rebuild can cost between RM 4k to 10k depending on the type of parts used. Anyway, this is for hardcore people.

If u only plan for a 10-15% power increase, the gearbox will be ok... I blew 2 auto gearbox in 1 year driving a Galant VR4. Now, I'm rebuilding one as spare. Long term project, so the cost is minimal when calculated per month basis.

For now, u don't have to worry too much. Main cause of auto gearbox failure is heat. So, a good ATF cooler is essential. Unfortunately, Mitsu recycle the engine oil cooler as ATF cooler which is too thick for the gearbox. Consider upgrading if u plan to increase the power.

Also, don't drive like a mad man or burn the front tires often, this will eventually damage the gearbox internals. FWD wheel spin is pretty common esp with auto gearbox.

 

[ShallowRiver]

care to share some light into what's involved when rebuilding a gear box?

 

[acbc]

For auto, u need to upgrade the clutch rings, seals, valve body springs, pump and torque converter.

Here's mine so far... doing it slowly due to tight budget.

For now, I've opt for remove all the 4WD components from the W4A33 gearbox to reduce weight and make it more durable since my car cannot be converted to 4WD legally.

Hi acbc,
You own a garage?

 

[acbc]

Nope. Pics taken from gearbox specialist's workshop. Waiting to pay them a visit next week for the latest update.
