Turbo for Gen 1?

Post by constapa »

Hi, can anyone tell me if it is a good idea to fit a turbocharger in my Gen1?
I know the problems with the turbo lag but i wonder, if i fit a small turbo (i.e. from VW 1.8L) wouldn't this minimize the problem? The specific VW engine has enough emmissions to turn the turbo from just 1500 rpm. I suppose this should be much easier for the 2.6L 4g54. Is that right?
Any help is welcome...

Yes, a small turbo will spin up faster and minimise lag. :armsup:

But, you never get anything for nothing. :cry:

A small turbo won't flow as well as a larger turbo, and will tend to strangle the engine at higher revs - top end power will suffer. :cry: :cry:

If you don't need the top end, go for it! :D

Here is a link all about turbo charging the 2.6 petrol.

http://www.4x4wire.com/forums/showflat. ... &fpart=all

This site also has a lot of other info on the series1 Pajero.

As the yanks didn't get too many Diesel engines (any?) a lot of talk is about hotting up the petrol engines.

Sel, i have already checked this site and the topic you suggest. They talk about turbo from a starion wich is preety big for my taste. With this turbo is seems that i'm going to losse traction every time i hit the go pedal... Thanks for help anyway...

Scott, i care for the low end as i climb a lot with my paj and i use it most for off roading. Do you know someone that has done something like that? (small turbo). Is he ok with off road performance especially in steep grounds?
I also thank you for your help.
Cheers ,
Takis

Sorry Takis, I don't know anybody who's done this, much less for a 4wd. This is just a general principle associated with turbos, and one of the compromises made when turbocharging a motor.

As a very rough guide, presuming the 1.8 has a redline somewhere between 6000 and 7000 rpm, do a simple guesstimation. (1.8*6000)/2.6=4150rpm, so I would expect you could get such a turbo to boost your 2.6 to 4000rpm without trouble, but beyond that I suspect power will fall off.

For offroad use, I'd be willing to give it a go.

Cheers,

Scott
