How can i get 200rwkw out of my GU td42t

install 350 chev then paint TD42T on the rocker cover it's probably cheaper..

i think if you want that sort of power you really should put a V8 deisel twin turbo as you can bring them in from states almost as cheap as doing a rebuild cam and a lot of machining to make the 4.2 make and handle the boost you would have to push into it to make that 200 mark at the wheels.....But all in all it would be fair nice to see it happen

well that is what im looking into at the moment

with alot of money. pretty much a custom engine. they sel occassionlly if you look around for 9 grand and over.... they cost alot more to build.

cheaper to just go and get a new duramax 6.0l from the states bullshit talk on tap and grunt to boot

yeah and custom engines cost a lot more then a lot of people think as i payed $15,000 for a 500kw asperated 383 stroker that can handle a 300hp shot of nitros ontop think you would maybe looking at that sort of figure as the deisel cost a bit more for machining and parts then the humble 308..........but if you have the money why not

Ask Heath Lawson. (HeathGu)

it's pretty easy to get 160kw out of them but if you want 200kw big $$$$$.
if you just use a bigger turbo, new intercoler and spend a couple grand on the pump, 4.6 gears then make 160 no probs. to make 200 need internals and custom air box, bigger better turbos$$$$$, water to air intercoolers, bigger radiators, the list goes on

160kw- $5000-6000 dempends on brands, tuners, etc

200+kw $12000-13000+
Heard some blokes are making upto 230-240kw out of deisels.

all terms are at the wheels on 35's of course

i know of a shop who could atleast steer you in the right direction if not build the engine for you... but hes in queesland so not much use... but itll be big dollars

Give Andrew at Ontrack a call. He will tell you how it is and wont bullshit.

On Track don't do heaps of deisels, better of calling deisel-tech in lilydale, works on a few comp cars and had his deisel pumping out huge numbers, most people have heard of andrew

yup, andy did my truck, does good work too. Still havent been for a run in his sequencial turbo shorty yet.. he was still working on it last time I was there.

Yeah, does do awsome work just look at hoon, birdy and his own car, my mate just got his ute cut there.(on track that is)

Meangu thanks 4 the heads up on diesel tec. I will go there monday morning & find out what he has to say.

Andy is on the board, although not as much lately, he may pipe up with some info.

ring desiel tec. 200 rwkw is posibble without internal motor work, ive done it before on 35 with 4.6s. your looking about 14000 to get that figure though.

about $9000 in pump work alone ,but then why would you do it and not do internals ????

It can be done, but if you want reliabilty and no overheating issues, thats where the cost comes into play.


I have one dyno graph here of 200rwkw, in fact its the highest one I have ever seen anywhere. It had a lot of smoke down low though.

I just sold my 80 series and have decided to go the diesel way in my GU, which was a 2.8 I got cheap. I'm building a td42 that will be capable of 180-200-rwk on short bursts. This is acheived with an aneriod that I can switch to allow more or less fuel from in the car. Nomally driven to 150rwkw
I personally wouldnt attempt this on a stock engine. I want a reliable cruiser with a shot of big power when needed, I need fast spooling and minimal smoke for everyday driving with reliability for outback touring.
Modified manifolds, and alike reduce the effort on the turbo, its better to make 200 rwkw at 25 psi with efficient manifold design than 200 rwkw at 35 psi boost due to restrictions in factory manifold design that require additional boost to flow the same volumes of air required.
My mods will include

These prices are in no way accurate but represent a guide only on what I have allowed for my engine

Currently porting the head. free for me but normally $500-800
HPC combustion chambers, piston crowns and exhaust ports. $600
New turbo pistons/ liners etc, hone parent bore 100% round and fit O/S liners for perfectly round bore. $1000
Engine balance. $300
Resize, rebush rods. $150
New head bolts and rod bolts $100
Line bore/tunnel $250
Deck-special surface grind for 100% flat $300
My design camshaft, about 10 degrees more duration and .050 more valve lift. Regrind and lifters $200
Custom extractor style exhaust manifold. $1000 steam pipe $2400 316 stainless
Custom plenum inlet manifold (can't get enough air through the stock log design. materials for me $200, built with labour $700
Custom roller turbo, one of our own combinations for both reliability and radid spool speeds. $2400
Valve springs. $200
Engine kit $1800
Pump and injectors $4500-6000 depending on pump
Head reco, pre comps, valve seats, guides. $1200
Dissasemble $300
Reasemble $1000, to install injectors, pump etc
Custom intercooler and plumbing $2000
Stuff I forgot $1000
3" exhaust $800
Custom dump pipe $200
Alloy custom 4" Air box $550 (as used in my 325 rwkw turbo gen3)
Stainless steel 4" snorkel, fully tig welded $600 (cost of parts only)
Prolley need a radiator $1100


With me doing all the works at cost and all the parts at cost I estimate 15K
I'm going to to do the engine and pump now and the custom work as the money comes in, got 11k for the 80 series so have to save some more.

Well Joel, you beat me to the punch. I was going to just say it will be between 18-25 k ish to do it. Looks like it will be if you include labour costs, but a good summary of costs.

A few things I would add would be to hpc coat the turbine housing and dump pipe. Better conrods and small ends ( Ive broken one rod already in my pursuit of this). A good supply system for the inj pump. Then clutch and driveline parts. The list can go on just fixing the weakest link each time.

What sort of i/c do you plan to use?

Good luck in this. I would love to see it once its done.

Andy

I'm going to try an ebay cooler, my LS1 makes 325 rwkw and the inlet temps are only 3-7 degrees above ambient with one, I mod them so they X flow.
I'm not so keen on HPC on the turbine as on petrol turbos (hotter) it can cause the carbon to leach out of the housing, cracks and scale appear. Probably a good idea on the diesel being that EGTs are 100-200 degrees cooler on diesel.
I have just had the rods Cryoed in the past but now I read that perhaps I'll get some made, whats another couple of grand...Ha Ha, the kids at last week.
Yeah, didn't include a clutch, I'm hoping to be able to use a modified 4 terrain, ceramic with cushions and some added clamp pressure, I'll get it set for max clamp from new but this will shorten the total life a bit.
I use a Carter 250 Litre per hour pre pump, delivery is about 7psi.


Gets dearer everytime you think about it if you want it right dosent it.

Joel

Can't wait to see that finished, sounds unreal!!

Sounds good
We have this fight at work all the time 14k-18k-20k whatever to build 200 RWKW or in the old money 268.2 HP

What sort of torque are these big kw TD42's putting out?

I think thats the key statement... yes it CAN be done cheaper.. but when everything goes tits up, then your rebuild costs + original cost =....

it costs a customer 14000 inc labour to drive in a standard td42 and drive out with 200rwkw with no internal motor work( all bolt on). i know of a couple of these engines still going with no problems at all after 2 years.now pgs says it going to cost( him) 25000 to build a preformance engine. the diferrence is 11000 plus labour. when your std motor lets go you pull off all your bolt on bits and bolt them to another motor.a std engine cost 3500 secondhand. that means you can go through 3 engines before your up to the price of a modded engine. now a modded engine doesn't last forever definetly not as long as 3 stds. just my opinion as the td42 is one of the most bullet proof motors i have seen.

$15k-$20K

you have got to be kidding, what sort of idiot would waste that amount on something with essentially standard internals!!!

your crappy OILER wouldn't blow wind up the ar$e of either of those!!

So what is the advantage of the diesel in a comp truck, and i don't want to hear the BS about being able to be driven in water, as any idiot with half a brain and some electrical and mechanical know how can waterproof an engine!! $20k for a top end comp engine, requires a decent drivetrain, either of those chevs would spit that nissan box out!! so surely all these SUPER td42 must be using a special GU box made of unobtanium!!

1 mad engineer, more like one mad knob, go back to the toyota site.
this post is about achieving 200rwkw out of a td42 not a chev, or anything else. you build one for less, see how long it lasts. read the original post.

I'm not going to question the worth of a TD42 but if you want 200rwkw why stay with a TD? Is it a point of making 200 or is there something I don't understand. 200rwkw is very easily and cheaply acheived with a lot of other motors. The obvious is TB45. For a lot less than the money eing talked about above I have a lot more and it is lighter etc etc.
I love my TD42T in my tow wagon but I am questioning it as a top end race motor.
