Safari GQ TD42 with a TD27 turbo???

[Hiikahard]

Hi all, I’m looking at Turbo options for my 91 Safari LWB, Automatic. I know there’s a lot of threads around but can’t seem to find anything specific to what I’m needing to know.

I recently drove a LWB Auto TD42 Safari the same as mine, but fitted with a TD27 turbo from a Nissan Terrano (Not intercooled). I’ve never driven any other turbo’d Safari’s so I’ve got nothing to compare it to in terms of performance, but I was quite surprised with how well it went. A lot of power in acceleration and heaps of grunt on the hills. The owner fit it to tow his horse float and has been running it for a while now without issue. I’m quite happy with how well it went and considering this as an option (mainly because the cost is much cheaper, and I still have to fork out for a suspension lift, some steel rims and 33’s before the wife pulls the handbrake on me!).

A couple of questions:
Has anyone had any experience running a TD27 turbo on the TD42. How does it hold up and how would it compare to other turbo options? Or does anyone have any opinions on this as an option?
And just to throw another random one in, would an early 90’s Isuzu Bighorn 3.1 Turbo work?
I don’t know a hell of a lot about turbos, so any advice welcome, cheers.

Hey man,

My brother n law knows of a guy who runs this set up on his farm truck in kerikeri he did a rough job but it works well. He has done proper jobs on other people's td42's so its achievable. I think they use the log style manifolds off trademe and modify them to fit the td27 turbos which going off what I have heard is you make them side mount on the manifold not top mount.

worth reading.

i think a td27 turbo would be massively undersized. maybe ok for small power increase and it would be working at its limit.

[albundy]

go to the patrol4x4 forum in Oz. You'll find all the info you need there. A TD27 will be way to small.

what if it was twin turbo? that's if you want something to show ya mates .

[Hiikahard]

Cheers guys.

Here's a couple of current listings on trademe. Any thoughts?

That's a good price. I probably could find someone coming back. Doesn't seem to be much description in the auction. Any idea what brand the kit is and the turbo specs?

I see the TD05 16g or 18g seems to be the most popular. Does anyone know where to get full kits?

Not too sure to be honest, but the manifold looks to be the same that DSR sold on trade me here for around $600. Turbo will be the same, Chinese I would think. I've got one coming over in September, so for that price, will give it a go.

On a budget i'd go,

There is plenty of people on the patrol4x4.com forum running that set up

You will still need to get a few bits those kits on trademe look expensive for what they are.

[Trundle]

All of these setups are chinese crap ,
Axt turbo australia also now use chinese shit in there cores
I have had one on my truck for 10 years that use genuine garrett internals ,
After bringing another axt setup into the country for a customers bus
it failed in a few months ,
After sending it to Steve murch for analysis turns out they are also on the chinese band wagon ,
When it comes to turbos regardless of the people that have success with china man shit , wait another 6 months and im sure its just a matter of time before they fail ,
Genuine holset , garrett , borg warner units are the go ,
If you on a budget you would almost be better at taking the gamble on a second hand unit ,
As many have mentioned the factory unit is a ht18 , tdo5 16g or simular will be a suitable fitment for mild tuned td42 ,
Keep in mind when purchasing wastegates , Turbo smart , genuine tial , or tubonetics are all good ,
Any chinese stuff avoid like the plauge , bending valves , failing diagphrams , poor seat quality are just some of the failures i have seen , and considering you can get a genuine tial 38 for 350 why would you spend 150 on something that will almost certainly fail ,
If anyone is to say i run some t3 t4 china man crap and its mint bla bla i drive hard bla bla , it will never last , They are just supporting them as they are guilty for owning the rubbish,
Please keep in mind that a failing turbo bearing will make its way into you sump oil , and can cause serious engine damage ,
And also keep in mind that a failed wastegate diagphram will cause the motor to run as much boost as the turbo will produce , which can put undue strain on big ends , h-gasket etc ,
As far as the cast manifolds , i have seen them snap in half just from vibration , i have also seen many of them are just finished with a belt linisher and are as bent as banannas ,

If you support the china man because your on a "budget" your tripping over dollars to pick up cents as it will only be a mater of time before you have to upgrade to quality parts anyhow , why else would people be selling the setups second hand !!

Now that's interesting to read. I thought they were supposed to be at the higher 'quality that you pay through the teeth for' end of the market too.

[tweake]

if i understand the guts of it, you really need to be planning the turbo around what fuelling and power level your chasing.
ie no point spending all your $$$ on turbo when you need the IP modified to get get enough fuel to push the turbo.
so if your got limits on fuelling, run a smallish turbo and make a wide usable power band.

[Trundle]

Tell me about it , I always use to push there product ,
When asking if they still use GENUINE GARRETT CORES ,
they said yes ,
After the unit failed at 12.5 psi , seing a max egt's between 4-500 ,
in around a thousand ks, they back pedalled , now saying they are garrrett and i quote FRAMED units ,
I sent it to the top turbo tech in australasia , (Steve Murch )
And he confirmed it was just chinese shit that caused the failure , fin just fell off ,
Never the less we rebuilt it with oem components , and have not had any further issues ,

[Hiikahard]

Cheers for the replies so far.

If I was looking at proven quality, what would 4-5k get me for a full kit including fitting? (not including the 3" exhaust which will be a separate cost).

I can go anywhere between Northland and Auckland to get it done. Might have to wait 2-3 months to sneak the extra coin away from mumsy, but I'm now thinking may as well do it right the first time and spend the extra $$$ if it's going to be worth it in the long run.

I'm also tossing up on whether to put money towards the 2" suspension lift, steel rims and 33 x 12.5's first and do the turbo later or vice versa. Any thoughts?

[DaveM]

Whats more important? Do you intend to go offroading, in which case the tyres etc may be more beneficial, or want better performance on road (and obvious benefits off road with a turbo too)

[crazyclark31]

You have to remember that the autos in these trucks are not the strong unit in the world and won't handle big power increases. You really need to be incorporating the cost of a good big trans cooler into a turbo fitment. Maybe even get trans checked first. No use to spend fewgrand turbo then blow the trans cause it couldn't handle it.
For what your looking at spending you should be able to get a really good unit fitted to your truck.

[Trundle]

I agree on making sure your trans is in check , i..e new service and after market cooler ,
Your other option for a resonable quality setup is purchasing a standard complete assembly , i just sold one with all lines etc for $1000 and then spend around 3 to 500 getting the the turbo freshened up ,
Running a std ht18 at 14 psi with a marginal fuel increase will give you a solid 40 percent power increase fit well within the budget and prehaps allow some for a suspension lift also ,
If you have any queries on td42 turbo set ups , pm me and i can give you the workshop number ,

Had the trans checked and serviced last week and all seems in good order. Has a good sized cooler fitted so fingers crossed the auto will hold up long enough to get some enjoyment out of it. I've heard the Autos have a habit of packing up, so I'm expecting it may be something I'll have to fix at some stage. I'm too worried about about major power, just enough to hold its speed on the hills and handle a bit of towing. I was quite happy with the power a TD27 turbo gave the Automatic Safari I drove last week, but after advice given on this thread and from others, not so keen on this option now.

As much as I want the extra height and bigger feet sooner, I do drive alot of open road hills. I'm assuming the 33's are going to reduce power even more, so probably do the turbo first.

you should damn near be able to get 33's under the guards on standard suspension
