: HOT vs. LPT

I was thinking of doing a ECU upgrade on my LPT but would it be possible for me to get a HOT turbo charger instead?

Would I be able to install it alright on a non aero car?

It seems a little bit cheaper to get a HOT charger.

The TD-04 Mitsubishi as fitted to the Aero requires extra pipework, and the car would'nt run properly without the Aero software. Best route is the remapped ECU from Nordic, Maptun, BSR etc. :cool:

Thanks a lot!

I am thinking of going with the nordic, is the downpipe crucial to replace. Also I am getting KONI shocks and new springs instead of the Roadhadling Kit.

Downpipe from stage 3 onwards. The jump to stage 1 gives the biggest bhp per $ increase. :cool: Suspension upgrade is a great idea, just don't forget the brakes, you'll find you carry more speed into/out of corners so some fast road pads won't go amiss.

Agreed, simply bolting on a bigger turbo wont give more power, it may mean reaching the maximum performance of the software quicker and for longer but thats all, you need a re map to make the most of the hardware upgrade.

Some of the guys here have the aero turbo with stock and stage 1 upgrades, its a bigger unit so may give more lag, the 3" down pipe massively reduces turbo lag............

I guess what I'm saying is chose a tuner that you can grow with, you will want more after stage 1 so bear that in mind, the Nordic guys seem very helpful too if thats your preference ;)

That's exactly what I'm running (Konis are "Sports" models). I love it - it's not too harsh and still feels very confident and responsive.

Highly recommended by moi...

You can put also Aero"s (HOT) software in your car. I have change Aero"s turbo, software , air intake pipe and fuel pressure control in my own 2.3t lpt -00. Max boost is about 1.1 bar and run just great:D

if i get a HOT can i just go to the dealership and ask them to install the aero software? if not, where can i find it then? indy mechanics?

you could just buy an Aero ECU but i think you need to have stuff changed to match your car, the immobilizer i think

i found a TD04 off a aero for $350 with 60K miles! anyone tried rebuilding a TD04? also, are there any other major concerns with upgrading turbos without the software, bedises the lag, and lesser performance as compared to the aero? i dont have the money at the present moment to upgrade to the aero software, unless someone knows where i can find it for cheap.;)

Have you got the extra pipework of an Aero or a 9-3 Viggen?

no, but i can prolly find it. what exactly is it, so that when i go to look at the turbo i can get all the necessary pipes etc. if not i can most likely get something fabricated.

You dont need to change the downpipe, for the turbo upgrade.
The only parts you require are
4 pipes(2 water & " oil) and 2 banjo bolts and washers.
Part nos
10-11066422 x4 washers
10-9136524 x2 banjo bolts
10-9174939 pipe
10-9174947 pipe
10-9179458 pipe
10-9182460 pipe
You are looking at about 100.00 for all the parts new, or if you can find an Aero or Viggen in a breakers, you can use them.
I think thats all.

Thanks to Wessy for this information. :cool:

i guess it prolly doesnt seing as how the aero almost never has turbo failure and it only has 60k miles. thanks again for all the help.
