Upgrading Turbo on a budget - need advice!

[Timbo]

An 11mm pump and no intercooler atm. Will be getting a top mount afterwards.

Good to see you still have the GU have you done the deed yet and got that home underway
sorry for the high jack

[Timbo]

Haha thanks Roofy. Hope life is treating you well.

Turbo? ..

[Timbo]

Yeah I mentioned the current turbo is a pile of crap. All I know is that it's a Denco and is too large.

Hi all,
My current turbo starts thinking about spooling at 2000rpm and makes full boost about 3000rpm. 4th gear flat knacker, lucky to make 8psi. 1st, 2nd, 3rd gear will make 14psi.

Have you had it tuned at all to see if is there an improvement.

Improving all the time mate getting closer to my op

Yeah mate. Not much else the tuner can do with it other than get a turbo that's matched better to the motor. TD42 just don't rev high enough to utilise the turbo's optimum range, which I can only assume is from 2000rpm to 4000-ish.. maybe more. Again, engine doesn't rev that high easily. (well I dont like too anyway).

Currently teeing up an A.R.E Intercooler from a bloke fingers crossed.

2000 to 4000 is within the main operating range of a td42. The only time you should be under 2k is when you accelerate from a stand still. Or maybe coasting along at 60 in 4th.

By the sounds of it you may not get the increase you are expecting due to other factors with a turbo change. If it cant easily exceed 3000rpm then you may have a fuel supply problem, be it the ip is worn out or possibly a restriction somewhere.

Who is this so called tuner?

As for the turbos either the mamba or kinu will suffice. Both are china built items so trying to compare the 2 in quality is not really measurable. I would be looking at something like the 18 6/8 combo.

They're just rough RPM figures. I'll try and russle up the dyno sheets from when it was tuned. Tuner is Diesel-Tec in Melbourne, Lilydale. All I know is, it's a shit to drive. I can't cruise up any slight hills in 4th gear, always have to drop down to third. Sometimes when starting at the bottom of a hill on road, I get up into 3rd and it just doesn't increase speed, so then I have to go back to second which is a pain in the arse. These aren't 45degree hills either. I don't know the angle but I wouldn't call them steep by any stretch.
