I am in the process of buying a garrett gt30/40 and am not sure if i want to spend the $2000 on a turbo which will have huge amounts of lag?
Let me know when you guys want me to send you my spare manifold for intercooler conversion
Marin was going to try my GT3082R on his Mav which is running the housings to spool up as low as possible, this way he does not have to but one to test.
My 40 flies as Marin well knows and makes good smooth power from low down but it may not suit a diesel. My engine size is the same, my rev range only 500 rpm more. So we were curious as everyone says GT28.
He is currently having a fuel pump built at more expence than the turbo
out of interest... where is everyone putting the filler cap for the system? obviously need to be higher than the IC itself - is this another seperate component i need?
While i'm at it, can you guys confirm that this is all i need to fit her all up:
1 x very bling IC (obviously)
Heat exchanger of some sort (radiator)
thermo fan (or two) inc wiring
Pump to circulate the water, inc wiring
Hose and clamps etc
Cheers Ben

Yes you need a high point to fill from. PM sent. Couple of options.
Oh and here is the latest from the M3 in the US, Carmen has done a top job over there of piping it up.
Almost there, I called in on Busman today and figured out where he want to run his pump and piping. Like all GQ's few are truly stock, twin batteries, after-market turbos ect ect ect.
The heat exchanger looks good custom with twin 10" Spal fans duel core and triple passed and the cores are better quality too.
Tomorrow should see a lot of the fitting completed.
Busman will however have to loose a little more grill, but we have yet to see if this means completely or weather we can retain the factory look. from the front.
I think I need my boost gauge and waste gate to be connected up after the cooler as well so that it takes into account my 0.5% pressure loss through the cooler cores LOL

Rum injected
TD42T shorty... got some bolt on and some custom stuff.
Read about it [url=http://www.patrol4x4.com/forum/showthread.php?t=18848]here![/url]

That's easy you have plenty of holes from testing you can use, just make one bigger
Finally finished hooking it up! Went for a quick spin and it feels more responsive, but importantly egt's are lower and they drop much quicker when you lift off. So i'll talk to Dieseltec tomorrow to organise the after dyno run. I think Matt's going to post some pics as well.

Grabbed a couple of pics with the mobile, next up Dyon time and a tune.
First a straight run no adjustments to fuel and then tweak it up to bring the AFR's back to where they were.
The first run should show the ARF's to be leaner as Marin's did due to the colder denser air allowing the addition of more fuel.

As for your Manifold I'll pm you
The biggest difference between petrol and diesel is the exhaust temperature is much cooler on the diesel. This is why diesels run smaller turbos for the same size engine.
There are other factors too, petrol turbos are usually sized to get more top end power and diesels sized to maximise low to mid range torque.
I'd be very interested in the results of trying a GT30 on Marin's duesel, make sure you let me know.
