DYNO printout for GU3 4.2 iTD

already has BD 3" dump pipe and exhaust, just get the fuel adjusted and pump tuned. atm the pump is set conservitavely from factory, so will hope to get a lil more fuel.

I've got the 2.5' system in mine , I'm looking at getting my injectors done or what ever they do to the pump.
I'll be interested to see how much better it is and how much more fuel you burn.

last weekend on a trip to Mt Gambier from Adelaide I got 7.78 kms per litre.

We drove less than 105kph most of the time.

Saw the chart, plenty of gogo.
So ive done the exhaust with the BD 3" system, getting the fuel turned up and tuned, so what do i do next?
Is it really worth the $2500 to upgrade the turbo????

Gday again Wayne,who the hell is charging ya $2,500 for the turbo upgrade ????????
Mine is getting the full 3 inch system, turbo upgrade and full tune for that.

meow.

rick.

Maybe that was for the full whack...any idea how much just for the turbo upgrade mate??

Hi Wayne,

I agree with Rick in that it won't cost $2500 for a turbo upgrade alone.
The Nissan one does an admiral job if it is setup right, I have seen one with 150 odd rear wheel HP but it had oodles of torque right down to 1400rpm which may work better for some people. The prob I see if you go for the MTQ worked turbo is you loose the opportunity to gain heaps more low rpm torque. It is still as good or better than factory figures but the factory turbo tuned properly will give you that much more. The upside to the MTQ turbo is you get quite a bit more in the top end, where people are running out of puff at 140kph, I am just getting started. It pulls real hard in 4th right up to 130kph (more if I want), slot it into 5th and it just keeps powering on. My dyno figures show my beast running out to 200kph but I have real trouble getting it over 160kph, it gets to this point pretty quick though.

Ask yourself where you want the biggest gain and you should answer whether to keep the turbo original and get the thing tuned properly or upgrade the turbo then get it tuned properly. MTQ will charge about 1200 bucks for turbo only mods and tune up, this is from memory as it was a fair while I ago I had mine tweaked. Probably only cost about 500 bucks for a good tune from the right bloke. Sorry I don't know of any over your way. Could always come for a drive over here LOL!!!

I preferred the high end HP and compensate the low end with crawler gears and I reckon this is the best of both worlds.

Good luck with whatever you choose to do.
Regards, Trevor.

Mmmmmm. turbo is nice...... but I'd rather be BLOWN !!! Hee heeeee...... :=))

I don't know it has been that long, I would need to take your word for it.

Wayne-o.

I work for United fuel injection mate and i can tell you that you need to come and talk to us about what you want, we are doing 5-6 of these a week mate, we are modifying the turbine housing ,fitting bigger turbine wheels, replacing dump pipe and fitting a 3" exhaust mate with EXCELLENT results.

Around 15-20% increase across the board.

Matt

Gday Matt.
You guys just did ours this week. The Gold one that Ken brought in.
Runs bloody nice now, SWMBO loves it.:):):).
Going for a drive this weekendto really try it out.

meow.

rick.

Rick

Yeah i know the one, very nice new rig you got there, did you get the pulse injector sorted out under warranty mate.

$2500 is for ballbearing turbo upgrade - but is still very cheap if its what they are offering.

And is it worth it??
Well 190kw at the wheels is quite often achieved with low EGT's.. compared to the massive <80kw at wheels standard. but if you go this far, you would go a good intercooler too.

190Kw from what???????

And do you consider a ball bearing turbo an upgrade????

From what: isnt this thread about TD42's?

Ballbearing an upgrade: No, I would consider a hair dryer an upgrade from a standard GU turbo... a BB turbo would without doubt be a backwards step...

Its school holidays isnt it?

School holidays, im a 38 year old fuel injection/turbo technician trying to make sense of someone saying they can get 190Kw out of a pre combustion chambered TD42T ,when a 1HD-FTE toyota twin cam 16valve,direct injection engine is struggling to make 170 .

Give me a break!!!!!!!!!!!

A well modded STD GU turbo will net you somewhere in the region of 125Kw and 380Nm of torque.

Mmmmmm.. Gotta disagree slightly with you mattche, a well modded intercooled, factory turbo GU WILL get in the vicinity of 150kw at the flywheel (dyno shows 155hp at the wheels) and around 460nm at motor (again, dyno shows 830 ftlb at the wheels)
Still a ways off Trucky's figures but I can't comment on those as I haven't seen them where as I have seen the above.
Without intercooler the hp stayed the same but the torque was only 750 at the wheels.
The above figures are the $2500 upgrade which included exhaust on a factory intercooled GU.

Ok good luck with it been doing this too long to get into a no ended argument about it.

We see these cars/engines daily and i have never seen an unopened TD42 with a modded turbo and intercooler go over 400 Nm with reasonable EGT's.

There are a few members on here that have this mod done ,might pay to find out what figures they have on there dyno sheet.

Matt

Pezza..

Look for the last 3-50 threads that people did on this, theres a dozen dyno charts. Here is Andy from Diesel Tec in Lilydale Vic's again 197kw at wheels GQ auto shorty.


he also has a twin turbo 80 series - sequencial turbo ... one small one feeds the bigger one. Nice setup, the car goes like stink from low low rpm and I think he now has this setup on his GQ too.

197 Kw at the wheels ,now that is good going,suppose you are going to try and tell me that is after spending $2500 on a STD TD42 are ya.

Any figure is achievable after spending a heap of money or going to twin setups, what i am trying to point out is some reasonable results after modding the STD turbo on the GU TD42 engine.

Guys ,sheep station racing is not for me but if you want to get upset about power figures go right ahead,we get good results and dont try and inflate power claims.If you think they are soft then so be it but 18 mods we did last month and if that says anything then i think maybe we are doing something right hey.

Matt

thats the standard $3000 Ballbearing turbo upgrade he does.

So your saying he inflates his power claims? talk about desperate to put others down cause you cant do the same.

Sorry if your place robs people to gain these power outputs, but dont put others down cause your incapable of achieving the same results for same price.

Ahhh thats right, school holidays isnt it... all the kiddies are on dads computer.

Hey Trucky,
I haven't seen a lot of this forum lately, been a tad busy, so most likely missed quite a few threads.
Hope you didn't miss understand me, I wasn't having a go at you or implying that your figures were incorrect, I just don't comment on things I haven't seen for myself or know about is all.
Thanks for putting up that chart again, I haven't seen it before, quite interesting, the figures I quoted came from the dyno printout I have here and from talking to Mike Vine up here (that's where this mod is done), his figures are from a factory turbo not the ball bearing one, mind you, for an extra 500 bucks I reckon if I ever went back to diesel I'd go the ballbearing option, this seems to give the same torque at similar revs but quite a bit more hp.
So how long before you have your 3000 bickies saved up :-)))

Cheers
Pezza

tis kewl pez.. didnt think I'd seen muchof u recently

how long? Well got rego, insurance on the GU currently waiting coin, and house insurance, and... :( and lookin at a set of 315 claws dude is selling at a great price on rims too :( :( :(

Hey man im not saying that at all, dont take this the wrong way.

I am having trouble seeing how a precombustion chambered engine that is RATED at 114Kw can now make 190Kw at the wheels with a simple turbo/intercooler upgarde.

That is all, i am just trying to put justice to it.

We dont rip people off nor do we claim unreasonable figures,hence my numbers are a lot less than you have qouted here.It is a good upgrade the one that we do and we believe that it is safe and cost effective BUT i still fail to see how they arrive at 190 odd Kw at the wheels with the same SIMPLE upgrade.

If it is not the same upgrade then maybe that is how they get such good figures.

Is it just the Turbine end housing machined with new turbine wheel, timing moved from .55mm prestoke to .74mm and about 1/8 turn of fuel and a 3" exhaust.

By the way not too sure how many SCHOOL kids would know about that.

BTW I am a 38 year old Fuel Injection/Turbo technician.

Happy to hear if we are way behind the eight ball on this mod.

Gday Matt, SWMBO is dropping in tommorrow to see Steve, look after my Patrol mate.

meow.

rick.

Will do rick, hope your still happy with it mate. :)
