Whats the best turbo

[THOMO89]

whats a good turbo upgrade for gu 4.2ltr TURBO DIESEL

[GaryP]

Best turbo for what , Diesel - Petrol , modest power - ball tearing acceleration, stock pump - race special - are you paying someone to do it or putting a kit together yourself, what is your budget ???? Lots to think about. You might be better off doing a search for different options, decide what you want then come back with specific questions.

[THOMO89]

will be getting pump mods eventually want to try and get something that comes on early and hard what do most people tend to go for anything has to be better than standard

[ledgend80]

maybe either a gt2860r, gt2871r or gt2876r all with a .64 hot side

[wade.s]

what about a truck turbo

[BeNoS]

im looking into this as well.
anybody on here heard of .64 rear housings causing problems with to much restriction for long distance travel.
as ive heard from a few people saying their diesel tuners are saying a .64 rear housing is to small and to go the .86
anybody on here heard of such a thing.

[ledgend80]

i would say .86 would be to laggy

[GaryP]

I have a garrett 2860RS .64 exhaust side on my GQ. It has been set up as a long distance tourer. I am running it at 12psi and a small adjustment on the fuel pump. I have a 3" dump to a 2 1/2 exhaust ( soon to be changed to 3 "). This setup has the power coming on from about 1200 rpm. It cruises very well, sitting on 100 kph the egt is showing 310-330. To date it has done about 25,000k with a trip to the cape. I am happy with this level of performance. I average about 13.5 l per 100 ks heavily loaded for trips which gives me a fair range.

ive actually just seen some screen shots of a dyno run with the 2860 .64 rear housing and restriction in the exhaust side is massive. pre to post turbo temps were over 200 degrees different. definately thinking . 86 is the better choice and with enough fuel shouldnt be to laggy at all.
the screen shots are on another forum btw

[RIZZO]

so bottom line , what is the best way to go for low down torque as well as high end power for my 4.2td 2876 with a .86 rear. is this correct, ive had the 2860 before, great turbo but a little sad up in the revs. looking for 180rwkw with large injector pump, will this 2876 do the job ????????

[Z()LTAN]

the 2876 with the .64 unless your going to install a larger inj pump dont go the .86

[RIZZO]

the 2876 with the .64 unless your going to install a larger inj pump dont go the .86

ok thanks, so with a large injector pump and .86 will i still have plenty of torque, like the gt2860 does?

[Z()LTAN]

torque is fuel derived, with a larger pump and the 2876r you will have more power for longer into the rev range.

[POW84]

ive gone from a 2860rs to 3071 due to it not being up to what it was intend for.. the 2860rs was great.. good a everyday driver awesome low down torque.. its also for sale too and done less than 5000kms

[patrol_uterus]

What do you think of the 3071, how does it go what mods are you running

[lovell86]

Yes would love to hear you thoughts on the new turbo and what you set up is.

Cheers

[POW84]

Yep sorry only just got the post... Will keep ya informed.. Also gettin rid of water to air and goin massive cooler on front... As soon as got car running will be doin pump as well... Was getting high egts with the current setup..bout 650c nothing stupid but i want more fuel so need to bring the egt first...

[Z()LTAN]

[UGOTNUFN]

whats a good turbo upgrade for gu 4.2ltr TURBO DIESEL

High Flowed Mitsubishi TD05, reliable ,easy to fit, awsome boost response.

How much is the turbo for sale mate?

[patrol_uterus]

Pow84 what A/R compressor and turbine are you running?

[tappo]

got a bit of petty turbo knowlege..... whats the difference between petty n diesel turbo induction???
basically the same, more air = more fuel/diesel = more power
therefore with a massive sized engine, 4.2 lts a larger exhaust housing shouldnt be that laggy....
anyone tryed BIG turbos?
GT3540?
T70?
....T88
any reason why not?..... proof of this reasoning???

[Z()LTAN]

Rpm is the biggest difference between petrols and diesels when looking at turbo options. Most diesels have a red line around the 3-4000 rpm whereas a petrol will be twice that.
Secondly when tuning petrols lean=bad whereas with diesels rich=bad.

The GT35 has probably been used on a smaller diesel before.

Big turbo petrol cars recieve their boost kick around the 4-5000rpm mark then they have another 3-4000 rpm to use it. No point doing that with a diesel.
