turbo advice td42

Post by **DEZ** » Mon Jul 14, 2008 9:50 pm

Im looking at getting a turbo kit for my td42 i had a look and couldnt find the info im after in the bible.

anyway im stuck between brands and want some experiences, i lookin for it so boost around 1200 so maybe a slighty smaller one, oil/water cooled, non intercooled, and to give a good reliable power few came to mind DTS and garret.

any advice comments welcome cheers

We raced with a mitsubishi turbo on a TD42. Intercooled we ran about 22 psi. Made boost from 1200rpm and max boost from 2200rpm. Started to run out of puff about 3800rpm.

I bet it was cos it didnt go fast enough.
Off the shelve kit good for 95-100rwkw's(with std pump), custom kit to go racing 180+rwkw's.

Have a bit of a search on the nissan section, there's a few workshops/retailers on here that do bolt on and custom kits to suit your needs. Most of these guys have tried a few different turbo size combos too which helps.

There's also a fair few backyarders that have tried commonly available turbos (VL commodore, 300ZX etc) with good results if you're keen on having a crack yourself.

interesting thread. i also have a td42, and would like to get a small turbo for it one day. i dont want big power, just something cheap that will help it keep its revs thru sand. how cheap have some of u guys turboed ur patrols?

Post by **twodiffs** » Tue Jul 15, 2008 3:52 pm

Would like a turbo myself, something not too small but not over the top either. 130-180rwkw would be nice.

Hoping coxy might run another 'group bulk buy' in about 12 months time.....'hint hint' .....

i run an axt kit and very happy with it

Do you want real figures or dodgy figures?

The limitation is the pump not the turbo. The Mitsubishi DTS turbo can make the required boost but will need a decent intercooler or the EGT's will be too high.
The reality is, and I'm sure Andy(Dzltec) would agree as I know he has an accurate dyno also, the standard pumps will only deliver enough fuel for about 95-100 rwkW.. If you want more you will need a modded pump.
I'd suggest a roller turbo, as with the right one you will get less lag and more boost (due to the larger compressor) which also means lower EGT's.
I know there are people quoting 130+ rwkW from standard pumps and bolt on systems but they aren't acheived on a dyno that is certified to be accurate. If you just want a big figure with no regards to how the vehicle goes, I'd suggest shootout mode Dyno Dynamics printouts. If you want the real figure get on a DTS, Mainline or Dynalog dyno.

Quite happy to supply some print outs if you want that show the pump running out as shown by the EGT's dropping and the power maxing out.

Cheers

With this expectation, how much do you think it would cost??? Be prepared to spend.

Matching air and fuel requirements to do this is the key. Yes Pgs, you are right, Gq pumps are only good for 95rwkw, late Gu up to 130rwkw, add gas 150rwkw, but dont expect this with the hitachi turbo.

This is no simple solution of one size fits all. I can guarantee to be able to give 2 of the next 3 things, just dont ask for the third. Power, cost, reliability.

I know it's not going to be cheap and I have the added disadvantage of buying in kiwi dollars when it happens, that'll bump it up another $1500 easily!

Is replacing the GQ pump with a late GU pump an option??

Post by **PGS 4WD** » Tue Jul 15, 2008 9:44 pm

It is possible to swap in the GU pump (an early non-immobilizer one) but if you want more than 130 rwkW the GQ is the better one to upgrade.

Joel,

I'll have to go against you on this one. A Gu pump with no electronics except a stop solenoid and already fitted with a 11mm head and rotor is the best pump to use, this will get around 130rwkw with the right turbo fitted. If you want more, then a 12mm h&r has to be used, it can be fitted to this pump with some modifications.

So determine your power figure then work backwards to get your bits organised.

I just had a turbo kit fitted on friday it got a 40% torque and power increase it makes 98rwkw and 484nm on 6 pound of boost with new injectors and dyno tune that was from turbo glide in wollongong sydney
im very very happy with that performance for the moment and then up the boost and maybe do some pump mods later on

Post by **DEZ** » Wed Jul 16, 2008 1:23 pm

40% thats alright, thats what im after not off its head boost just a half decent kit that makes a decent increase. So what actual kit is that and what prices you get ?

cheers

Post by **brettsGQ** » Wed Jul 16, 2008 2:09 pm

it is a turboglide kit just look it up on the net just google turboglide and it will come up and all prices are on there i also got the diesel fuel sytem tretment aswell it was money well spent for shore

happy to help

Sorry I know it's a loaded question for you, but in your opinion or experience what would be the right turbo kit??

Check the for sale sections. One of the fellers from the last buy is selling his manifold.

Interesting, I know you do your own pumps, I'm still limited to buying them, took a while to get them right to. My supplier wasn't able to get 150 + rwkW from the GU pump, it may have been a cost issue I don't know. Perhaps it is cheaper to fit the 12mm head to the GQ pump than the GU??

There is no right kit. The turbo used to get to 130rwkw is different to 150 and 180. You wont have 180 with great low down torque, you wont have 130 with high end power. You can future proof yourself by using all the components to make 180 but detuning them until you have it all in place.

At the end of the day I'd be happy with something around 140-150. I'm on 35's, I live and work in an area that is bl**dy hilly and steep and i'm towing tandem trailers at times with building materials (my job) so i need low down torgue and power as opposed to high end output, plus for 4wding and hillclimbs etc. I reckon if I go Denco, AXT or DTS then basically I can't go wrong - correct?

Post by **PGS 4WD** » Thu Jul 17, 2008 7:50 pm

None of the off the shelf kits are going to give you 150 rwkW, you will need a more customized system and an efficient intercooler for starters. Thats about twice the power a standard GU TD42 makes, so for twice the power you need twice the air volume and twice the fuel.

do all the GU pumps have the 11mm H&R and can the boost compensator from a GQ be fitted to a GU pump?

Post by **Dzltec** » Fri Jul 18, 2008 9:08 am

No, not all Gu pumps have a 11 mm h&r. Yes a boost comp can be swappped over if you know what you are doing, there may have to be items altered. If the boost comp is on a gq 4.2, its probably a denso unit, as you cant buy zexel ones complete.

So it would be a mater of finding the right GU pump, removing the one from my GQ, taking it to one of our local diesel places and having them change the bost comp over and checking out the GU pump.
Then me fitting it all to my GQ.

at least with fitting a newer GU pump i wont have to spend huge is a rebiuld on my current pump. (hopefully)

Have you ever heard of Dorans Diesel in townsville,
or any one els have an opinion on them or any of the other diesel places here.

Found a T4 Garret Turbo, What sort of figures can i expect from this running at 8psi of boost? (Topmount Intercooler to go with it but i havent looked into that yet) Just so i know what i need to add to the list. Same as twodiffs work and play horse.

Post by **DEZ** » Sun Jul 20, 2008 8:43 pm

ok had a bit of a look found out turbo glide kit boost comes in at about 1900 does any one know another of good quality that boost will come in earlier or is there anything you can do to make it come in quicker?

cheers
