Turbo Upgrade

**wozzlegummich** · 18th January 2006, 08:17 AM

Hi All,

This is my first post so please be gentle.

I am considering upgrading my turbo with a Mitsubishi unit from Dynamic Turbochargers. They are quoting up to 50% more grunt.

My main issue is the off boost performance (Dynamic say that it will boost a lot lower in the rev range) Being an auto I cant get up my steep driveway from a standing start - the auto just goes to stall point and the turbo isnt making any boost at that point.

I am just wondering if anyone has done this upgrade and what was the result.

i don't know anything about turbo upgrades however the first questions the lads will ask is which landrover you have and which moter is fitted

i'm sure you will get some advice

Yeah - didnt realise I had to add my signature manually - DOH!

If the engine is currently able to drive the auto to stall point then increasing engine power is simply going to get there more quickly.

Maybe you need to have the torque converter looked at. Maybe a higher stall converter is needed.

My thoughts anyway - or am I missing the point.

I think he is saying that the 300Tdi does not have enough torque at 1600 rpm or whatever to pull the skin off a rice pudding. Ie its sits there grumbling to itself but the engine will not rev and actually drive the car forward. The 300tdi is a high torque rise engine with it all between about 1800 and 2600 rpm. I LOOVE to follow one up a really steep hill in my 3.9 V8 and when they fall off the torque curve , go up behind and say Hurry up, aren't you supposed to have more torque than a V8???

Wouldn't it be cheaper to try low range?

I would want a demo before I believed that a bigger turbo could fix it. Gas injection maybe.

Mate Low range is the go - the iup side of this is that its good to engage and use low range regularly - what better than every day up and down the driveway- i used to live in a place with a shocker dirveway - low range was a breeze - and it got me used to changing from low to high etc in a hurry.

Seems a bit odd to me.

One of the supposed benefits of an auto box over the manual in the diesel is that the torque converter allows the engine to get into the sweet zone starting at 1800 rpm as opposed to the manual that requires the driver to slip the clutch.

As for Tdi's slowing up on hills that depends on the drivers selection of ratios to keep the donk spinning in the sweet zone.

Been there, done that.
Go for it. My TDi used to do the same and needed low range to get up my cousins drive. Had the DTS turbo job done and it had no more issues.
Mine was an auto also. Its probably the equivalent of chipping a TD5.

I have heard that this turbo upgrade is a water cooled turbo and that it puts more pressure on the cooling system and costs a **** load of money l have put a 3" exhaust system a k+n air filter and the pipe leading from the filter to the turbo replaced it with 3" pipe ( the old plastic pipe closes up under throttle ) also pull the engine breather hose off cut it shorter ( just before the turbo ) and refit into the turbo pipe . Yeah l know what the hell is he on about but lift the bonnet and take a look around.
