Outer Limits 4x4 Board

hi...i just picked up a factory td patrol ute and was looking at these upgrades:

intercooler (front mount)
3" dump pipe (already 3in straight through exhaust)
larger turbo with fuel pump mods
increasing boost

my questions are> how can i give the current turbo a bit more kick, because if i dont need to i wont upgrade the turbo, im worried about how restrictive the inlet pipe is from turbo to manifold, it would be lucky to be 1.5in ID. is there anything i can do about that? when the turbo is only that small as an outlet?

i also plan to put it on gas as well. should i intercool it before i get gas, or after? also what size intercooler would be adequate once its on gas.

does a 3in dump pipe work with the standard turbo outlet?

will be fitted with an EGT and boost gauge. when i put it on gas i imagine would have a 2 stage boost controller for when there is no gas in the system.

i have done a lot of research and got some great information, but there are a few questions that still pop up. sorry if some of it has been covered before. any info from experienced people will be greatly appreciated

cheers

My question is, what do you want the truck for? Comps - then go with the total replacement turbo, and grill replacement intercooler, and the works.
for a weekender, just get the std turbo mods and a IC off a Patrol 4.2 or 2.8 (cheaper but the same) IC

how can i give the current turbo a bit more kick, because if i dont need to i wont upgrade the turbo,

The difference in a stock turbo with more boost, V a total new system is like a 1000cc morris to a skyline.

i also plan to put it on gas as well. should i intercool it before i get gas, or after? also what size intercooler would be adequate once its on gas.

I'd cool it first..

does a 3in dump pipe work with the standard turbo outlet?

yes.

what year is it?

If its post 03 you have a good pump.

Doesnt matter if its comp truck or not its up to you how much power you want.

I wouldnt bother getting gas waste of time in terms of complexity and stuff... you can get your power gains else where if its economy your seeking well i just wouldnt bother with it...

i would first get a 3" exhaust.

then get it tuned with more fuel and boost pumps it up another 20% to about 100 rwkw..

2. is where you need decided how much power you want?
for 2g you can get a roller bearing turbo fitted to the factory manifold with some adaption.

3. - fit a good front mount with proper piping
- roller turbo and extractor manifold
- 4" snorkle air box
- custom air box

asses this level of power however your massive gains will be with the pump.

4. another 2 - 2.5 g on the pump and then you'll have 180 + kw with around 20 psi.. pending on how u do your other stuff such as manifold and such...

what year is it?

its a 2001. whats the difference with the pumps?

it will be used for everydy driving, work ute and travelling. plus wkend plays and towing the comp truck.

how do you mean gas would be a waste of time? so far i have been reading fairly good reviews?

it already has a 3in exhaust. i would like to put the 3in dump pipe on it, but if i end up with a bigger turbo would the same dump pipe fit? or would resale still be okay?

roller bearing was going to be the turbo of choice (havent gone so far as a specific one) are the standard manifolds NOT extractor manifolds? are the gains good for the price of a new manifold?

around 200 odd hp at the wheels would be nice. is this far fetched for the standard turbo setup? would the pipeing be too restrictive?

what do people think of internal turbo mods?

i just have a standard airbox (k&n filter) with safari snorkel. would that also be too restrictive?

sorry about all the questions. its just that there have been plenty of these done before and lots of experienced people. so i thankyou all for your help

PAUL

Your in Brisbane right?

If you are go to www.highwaydiesel.com.au speak to Craig or Steve here and they will be able to help you out properly.

Depends on the turbo, but probably not wont fit the upgraded snail.

roller bearing was going to be the turbo of choice (havent gone so far as a specific one) are the standard manifolds NOT extractor manifolds? are the gains good for the price of a new manifold?

so you mean a bearing turbo on std manifold V bearing on custom manifold differences?

Your smoking pole. thats 149kw - not a chance standard snail/pump etc.

what do people think of internal turbo mods?

Like the MTQ replacement gig?? Mate has it and loves it, I was put off a bit by stories of housings shitting themselves.

i just have a standard airbox (k&n filter) with safari snorkel. would that also be too restrictive?

Depends who you talk to, airbox is ok snorkel I'd say is ok, but others go for 4inch cause the comp boi's do...

yeah bogged the difference between roller bearing on standard manifold Vs custom extractor manifold? manifolds wont get much change from $1000 would they?

thanks mickyd, i live close enough to rbisbane to go there for a diesel specialist. ill check them out.

a bloke i know had the internals done on his standard turbo setup (was factory intercooled though) not sure who did it, but it made 165hp at the wheels on 33" with a 3in exhaust. thats why i asked. its not cheap though.

i heard u can fit a larger plunger (correct terms????) from a cruiser pump to get a bit extra out of the standard. im not going to go crazy on power upgrades. but cooler is definite, dump pipe (whether it on this turbo or new) and i would say gas too.

any other options, like injectors or just a really good tune before i start doing all this?

PAUL

i will give you some cash towards your new turbo in exchange of your old turbo and manifold , pm me first if you decide to bigger turbo it

Here's the results of my MTQ upgrade

Vanbox, you have 3 options to choose from.

Fit a dump pipe set boost and fuel levels to suit = 85-95rwkw, fit i/c, close to 100rwkw.

Above with garret bb turbo, requires new dump pipe, diff fit up pieces but will bolt to standard manifold via an adapter. Will require an i/c. Power dependant on pump head and rotor dimesions, you may get up to 130rwkw.

If you have a small head and rotor then you can fit lpg to add as the extra fuel source. We have found a simple lpg setup that works off vapour rather than converting liquid, ran a vehicle already fiited on the dyno, was impressed by power levels. Yes you could use a two stage boost controller depending on what boost you are running.

Or you can go 150+. This requires full pump mods, a very good i/c, a high mount manifold, either tubular or cast, doesnt matter. Better air filter system. Still can use lpg.

Above all else, whoever does this needs to know how to set them up properly, monitor egts when tuning and your vehicle must have an egt gauge as standard.

Hope this helps. We have dyno sheets to back up above figures. Do it in logical steps, then you wont be replacing parts again and again.

outback_pootrol.....its looking like i will go roller bearing down the track, but that will literally be down the track. so i would be interested in parting with it. it currently has done 140,000km.

dzltex. thats some excellent information. i think ill leave the dump pipe off this exhaust, save my dollars for a roller bearing garret (any recommendations) then dump pipe, and intercooler (again, any recommendatioins on size, brand etc (front mount))

what sort of pump mods will help it along?

i live on the sunny coast in qld, heard good reports from custom offroad kunda park (built heaths outback ute, 260hp). thers a diesel pump and injection service in caboolture to. any other recommendations?

where should i go for dieselgas? there are only 2 registered suppliers/fitters and they are in NSW. i will go there if i HAVE to. are there any fitters in qld?

thanks again

PAUL

when your ready mate let me know how much.
thanks dude

i have no idea what they are worth. and prob wouldnt be selling the manifold with it, will just get an adaptor plate. unless the price is right and i get an extractor manifold with the RB turbo. but i imagine big $$$$

what would be looking for out of the kit? other than turbo obviously.

im going to have to price up a new turbo first, but if ur interested the turbo may happen sooner.

cheers

PAUL

Bearing turbo setup, complete drive away just drop car off and pickup as I was quoted, which included everything, screws, nuts, caps, etc right down to new coolant, fully dyno'ed and it was over $5000 - no suprises... that was all new, using OEM manifold with adapter.

I have yet to ask Andy how much his was compared...

So you really need to think about what you want from this truck..

paul ill get the place i was talking about with the diesel gas place by tuesday .... forgot completly about it...... good to see another convert to a ute







...... need to ute the shorty

simon. clear your schedule. the shorty will be a ute in due time. and guess who is going to make the cage and tray for me???? yep thats right. haha. wen money and time permits it will happen.

bogged, thats NOT what i wanted to hear. but at least i know what i would be looking at. thanks. i saw a couple of GT25r or similar (about 300hp) for $1500. where would the rest of the money go to? pump, boost controllers and things. intercooler as well for $5k?

your right bogged, i have to work out what i want. if the roller bearing is too expensive ill 3" dump pipe, intercool and turn the boost up a lil. then put it on gas and that should keep me happy. i just dont like the size of the intake pipe post turbo. WAY too small.

PAUL

paul i just forgot..... just got up i have a RB turbo and I/c sitting in the Shed ..... funny what you find when you look if u want pictures pm me ur email mate

What about other turbos with a T3 flange that are ball bearing turbos, so something wtih better perfomrance that is the same flange, T3?

what turbo to get?

can anyone give me part numbers and details on the ideal garrett turbo that will fit my standard manifold (adaptor acceptable) and with front mount cooling and pump/boost mods give me boost at about 2000rpm. and when fitted with gas somewhere around the 180HP???

im reading and researching but would like to know what works and what doesnt because its been done so many times before.

is it bad for fuel economy at cruising (100-120) if its on boost? car sits at between 2100-2600 on highway cruising. will it suck more fuel? where would be a better place for boost?

whats the advantage of ball bearing? faster spool? is it worth the extra $$$

cheers

PAUL

vanbox wrote:will it suck more fuel?

you dont make power without fuel....

Vanbox,

we have developed a bb garret turbo kit to do 130rwkw on a late gutd42t. Its not a straight bolt up fit, things do have to be made, but will bolt to the manifold via an adapter. When finished it does look factory if done properly.

Part numbers we are keeping to our chest a little as we took the time to find out what works and what doesn't, but if you want to buy the kit you will find out the part numbers.

garret turbos of the correct size have a t25 flange. So an adpater is required, which comes in the kit. Thers is some fabrication involved as well or we can do the whole lot.

When cruising at 100kmh the vehiclew is only making 15-30 rwkw, 2-6psi of boost. This is not consuming a lot of fuel. Use all the power, you will use more fuel. You dont get something for nothing.

The advantage of a bb is you can use a larger turbo for the same boost rate rise and are more efficient.

Hope this helps.

Andy
