whats the "ideal" turbo for the safari.

[gary_in_nz]

ok so whats a good intercooler to go with a turbo setup. looking at water to air, i run 12psi from a td05 setup??

[Windsock]

PM me your email address if you want a copy.

Cheers, appreciate that, PM sent.

Some photos of my setup, the turbo is a T3/T4 hybrid with a/r55. Manifold was made by performince metal works and a warter to air intercooler with a 3" exhaust. Works very well.

[DaveM]

doby, how many km's on the motor when you threw the turbo on?
Any pump mods?


Cheers

[doby]

Motor had done 180,000kms when I turboed it, has got 250,000kms on the clock now with no probs at all. When I removed the sump to weld on the oil retern fitting, I replaced all of the big end berings with new ones. The old ones still looked fine thow, wernt through the hardining. No mods to the diesel pump, just wound up the fuel presser a bit. It will blow a small amount of black smok untill it comes on boost (around 1400rpm) and then clears up, just overfueling. This can be overcome by getting a boost sencertive injecter pump off a factory turbo td42. Not realy a big issue thow, im not going to bother.
Hope that helped.

No one by any chance would have any cad drawings of a highmount manifold would they? bit of a long shot. but would make it easier to make by a lot. Thanks for posting those photos should be able to work from it trial and error and a lot of time i think

[doby]

Sorry mate, no cad drawings but hears a couple more pics. Im no welder but you should make the manifold flange a min of 14mm thick otherwise they bend with the heat and blow exhaust gaskets.

Go into Performance Metal Works in Silverdale, they've got an old head of mine you can work out the flange pattern from. Don't touch the shiny alloy bits still bolted to it though

[BEAUTGQ]

the flange itself isnt a proplem because you can buy them for td42 from autotech in east tamiki i think. im pretty sure they get them from autobend ltd. just the pipe cuts/lengths is what i was after. no worries though

AutoTech ones are based on the flange pattern from the head I gave to Kerry when he built my manifold 4yrs ago.

[Shane]

Does anyone know what vehicles a TD05 come out on?

[Safari Swb]

think theyr off a mitsi evo mate.

[gary_in_nz]

defiantly a mitsi turbo

[tgaguy1]

Does anyone know what vehicles a TD05 come out on?

4m40 diesels (2.8 litre)

[BEAUTGQ]

next quiery is what happens about a wastegate on a tdo5/td42 setup? any one know, got to get my head around what turbo to buy been looking on trademe not sure whether to buy a good second hander or a cheap new one eg from DPR probly a silly question but havent done anything with turbos before.

[Safari Swb]

dont buy one of those chinese 1s they are shit

[BEAUTGQ]

so go a good second hand one off an evo then and then what about the wastegate are they internal or do i need a flange on my manifold and buy a wastegate? What size is best ie 38mm big enuf with a 10psi spring? also Is an actuater another word for waste gate or what is this?

Cheers

We've used a 2.5 petrol Subaru turbo on the support truck with a J pipe to keep costs down, works great. The pump is maxed out and the turbo has more potential. Plenty of potential if/when the fuel pump is ever upgraded. The turbo comes on strong from before 1500 and goes great to over 4k. Completely transforms the truck.

Nathan, the standard flang part number FL9072 is in 10mm and will cost $79.40 incl gst, the next size up would be 16mm, if you wanted the flange in this size it will cost you $109.40 incl gst

I'll be ordering mine fairly soon. I've always wanted to give this a shot.

Schedule 40 bends (steampipe) are just $7 each from steel and tube..It ends up being quite a budget project.

[KiwiBacon]

The wastegate is a valve which bypasses some exhaust flow around the turbine wheel to keep boost levels down to a set level.
It's got an actuator (usually an aircan with an internal spring) which pushes on an lever on the side of the turbo. The lever moves an internal flap to let more or less exhaust bypass.

You can change the boost levels by lengthening or shortening the rod (shorter = more boost).

well im slowly gathering all this info together been talking to a rally truck mate of mine and hes helped a bit and offered assistance come build time which is a good help. so looking to buy waste gate, manifold flange, turbo flange and bends. also oil lines blow off valve and some silicon bends for intake etc also most important a td05 haha

[tweake]

..... so looking to buy waste gate....

i think most turbo's you might fit will have internal wastegates.

[flyingbrick]

Do blow off valves work on a diesel? they have no throttle body so wont have vac in the manifold to pull it open.

You won't need an external wastegate or a blowoff valve.
You can use fuel hose for any straight section joiners, it easily handles an oil from the breather and air temps up to 150C. Steel bends and straight joiners can be a better option than using silicone bends. It depends on how the layout works.

Anyone got a compressor map for the Td05 that's been recommended?
I have a map for a TD05-16G with "small compressor wheel" in the header. It looks suitable but it might not be the same turbo and there's no turbine map.

can be made to work ok. not a lot of benefit on a diesel unless it has egr butterfly.
on some motors they do help when doing a lot of fast gear changing, basically allows the turbo to free spool a bit.
IMHO its a waste of $$$ which are far better spent elsewhere.

[BEAUTGQ]

yea thats what i thourght that that diesels didnt need a blow off valve but then i heard that it was good to have to release the boost pressure put on the turbo when you button off (to change gear) and the turbo is still pushing but if its not nessesary then i wont put one on dont like the bloody things anyway and will save me coin so im in! apparently the tdo5 that comes on standard evos etc is the 16g version and doesnt have an internal wastegate. next thing is whether to vent wastegate back into exhaust or just dump somewhere away from everythng in the engine bay? downwards id be guessing

A vented wastegate is an exhaust leak.
It will make the WOF man very unhappy and does bad things to everything in your engine bay too. Not to mention the possible health side effects.

I don't know which Evo turbo you're supposed to be looking for. But this one google picked up has an internal wastegate and a really gangly actuator bracket. Hope you've got room.
An old workmate with an Evo 5 was running an internal wastegate.

[BEAUTGQ]

Yea thats also what ive heard. just wondering how do you adjust boost prerssure with an internal waste gate? and what performs better if any difference at all?

[monstr]

Hi BeautGQ ,If you like drop me a pm and come around and check mine out ,im running a modified Skyline turbo Ext wastegate etc ,it will give you some idea of what sort of HP you can get out of these motors ..Steve

Which skyline is your turbo from and why did you go for an external gate? I thought all the skyline turbos had internals, my ex-skyline T28 does.

As for adjusting boost with external gates, it's dead easy. Cut the arm and thread on a sleeve nut. Then you can easily adjust the arm longer for less boost or shorter for more boost.
