So youve got about 108 degrees going in if your turbo is efficient at that boost level and have you measured the out temp under full load.

MAtt

So what is the temp when you are on full load,what is the ambient temp at the time and how much boost are you running.

Looks red-hot mate, I was told those airboxs were only good for flowing 135RWKW more or less. When on the dyno next time remove lid of the air box and then see what she makes...my bet is you'll be surprised Before you go pulling the intercooler etc of the rocker cover to mod the breather, why not b...

I think you hit the nail on the head Garth, i just spoke to a guy in SA who told me to restrict down to a 1-1.2mm orifice. I am currently pulling just over 70PSI under full RPM load. I am going to need to mod my crank case breather again i think as i dont have it going through a catch can. I think ...

ha yeah for sure mate. what sort of light mods were you talking about that should be done to the ht18? Slight modification of the turbine end and wheel thats all. MAtt as in larger diameter and different wheel(ceramic)????? No mate,reprofiled turbine wheel. Get ceramic out of your thoughts all toge...

No we dont mate,but have a hunt around wreckers etc you may find one that someone will sell you,im trying to look at this from a budget point of view for you mate.

ok well i have also found a GT2560R for $1150 which has the same specs but is rated to 300hp. and for $300 less is it gunna do the same job. also madrolla could you send me the specs of a HT18 and what it is off and where to find them. also what sort of $$ for the turbo and modifications would need...

It goes to show that at high boost levels, the ht18 just can't cut the mustard. Whereas a well matched Garrett stays reasonably level. Have you had any other turbos beat the ht18 when modified madrolla? Andy For the lower boost levels it performs really well and boosts as quick as the garret BB and...

Andy thanks for that info,ive got a few here of the modified STD wheel HT18 that i have just fitted to my GUIV,std wheels and tyres and diff gears. http://i433.photobucket.com/albums/qq51/madrolla/MATT07.jpg Then the same one with higher boost,4.3 diff gears and 35" MTZ's. http://i433.photobuck...

from what i've seen the GT2860rs with the .64 turbine housing will make boost from idle and you'll have 10PSI before 2000rpm. Seen a lot of threads mentioning this but yet to see any evidence. Does anyone have actual dyno charts showing boost in conjunction with rpm. Went down this path with a simi...

And how do they go with efficiency and managing EGT's at higher RPM and engine loads.

just a thought is the mixer open to run fuel the mixer is the gas part on top of the carby some early ones use a manual lever much like a choke cable later model gas system use a solenoid vacuum i think but if thats close it explains the system there is a silver leaver in the car, the only thing i ...

Has anyone got pics of a GU turbo intercooled kit Yep i reckon it might be. :D What are you going to use for the oil drain and feed,the early engines dont have the same feed system as the gu. You will also need to organise a drain fitting in the sump.!!! Other than that its a bolt up deal,you may h...

Plenty of things can be done,like upgrading to a different turbo that will spool earlier etc,the pump can be changed for an earlier type without the TCV but the engine light will be on all the time. Are you upgarding the intercooler??. We are currently trialling a pump and turbo setup on a comp truc...

38L seems a bit small if you want food for a week and some beer too. Go the 50 litre waeco, its a set and forget fridge, has a temp display, 10 volt cut out, mine runs at 3 deg for 3 days with no charging before it bdrops the batt to 10 volts I payed $850 for mine and am very happy with it Engle di...

Injector pump, is what I meant. :oops: Had a mate (fitter) look at it yesterday. It's leaking fuel from the front side. There's a pump specialist in town that mainly does heavy diesel jobs (cat, etc) who'll do the job at "mates rates". It was suggested that I could leave it go, (since I'm...

Speaking form experience, everything on the 2.8 is expensive........ There is a mob in Melbourne which is probably no good to you who overhaul injector pumps called Marrasi & Williams but thought I would telll you anyway. How much is $$hit loads? You could probably pick up a second hand one fro...

My right hand pipe (2') runs tight to the block and runs under my bell housing and joins on to the left side just beside the join of the gearbox to the bell housing, then into 3'' mandrel system all the back.. My front shaft does touch the pipe, but only just and when under full compression, if u s...

I'd suggest the same size housing for the front as you were using origionally if one is available with an anti-surge front cover, it sounds like you were experiencing compressor surge. They are sometimes hard to get but do work better. Its similar to when you put your hand over a vacuum cleaner, th...

Been a while since we started this project so probably is time for an update. Theres been ups and downs, but you get that with R&D. Car has been in twice so far for different mods. ------------------------------------------------------------------------------- Housing 1 : Picked up car, it had ...

A/R is a bit small,it will spool earlei but run out pretty quick.

ah right so after 93 they went the light ones not rebuilt 235000 on it so should be right. wanted to check better to run milder psi in that case? correct, from late 92 they went with lighter pistons except on factory turbo models which retained the heavier piston etc. No factory turbos until 99 hey...

i have a 03 lux 3.0td and when i pulled up to the lights today a shit load of white and blue smoke came out of the exhuast .... when i took off to pull over got to say 40 km/h it went away i took a chance on driving home and it would only smoke after i stop at the lights ( very embarassing) and be ...

it appears to be a no fuel problem. fuel to pump but no fuel out. cracked lines and nothing coming out. it is as if the pump is in the no fuel position. which i thought could be a fuel cutout solenoid or the ecu telling the pump to go to no fuel. so timing isn't out, otherwise it would still pump. ...

I have a gu with a zd30 that just stopped and will not start. I was driving down the road nothing out the ordinary, when all the a sudden the engine just stopped. No funny noises or anything, just stopped. I checked all battery connections, fuses relays and links and all appear fine. Checked for fa...

So what are the ideal mixtures (measured) for LPG.

I run mine at 15.5 at idle and around 13.5 on cruise,dont they say that it should be 1 point higher than petrol if using stoichometric value.
