Has anyone on here fit a larger turbo on their 180hp TT? I have a Garrett T28 that I would like to put to use. I may have to make some custom fittings to get it in their, but should be worth it! I'm getting ready to do a full exhaust with a high flow cat and possibly some port work. That along with a larger turbo and the right software should get me close to 300hp. The stock fuel system appears to be able to handle that without any problems...

Are the 180 injectors the same size as the 225 injectors? Maybe you want a bigger intercooler too.

Jason

From what I can tell so far the 225 uses the same fuel system, including injectors, as the 180. Just a different fuel mapping in the ECU.
The larger turbo running the same boost as stock even should make more power because the charge air will be cooler and make less work for the single intercooler to handle. As you increase boost on the smaller stock turbo the air charge temp increases significantly. Hotter intake air = less power and more detonation. When the ECU detects detonation in the cylinders it will retard your timing and cut back the boost level to try and protect the engine.

without modifying the housing (making it smaller). There is a balance that must be maintained in tuning your turbo.

BTW, any temperature taken away from the intake charge also comes off of the exhaust. Also, the intercooler is gonna do the same "work" regardless of what's going on upstream (at the turbo).

Hi Jenner,

>Hey Todd. A few questions for you.
>Have you installed a K04 turbo or a 2nd intercooler in a TT yet?
>What are the hardware and labor costs for each of these?

<I>We have had a lot of trouble getting ahold of the transverse style K04s. They are different than the A4/B5 K04s. We have one on a 1.8T NB and are completing chip work for it. We really want to offer a K04/intercooler upgrade for the TT ASAP, but have no current ETA.

What kind of cost do you think this would come to?

I was kind of thinking $3-4000 all told, but have very little idea.

Jason

Think you have that backwards about the intercooler. The air goes through the turbo BEFORE it gets to the intercooler. The intercooler is very effected by what the turbo does because if the charge air is too hot the intercooler can saturate rendering it almost useless.

Jenner

I mainly wrote him asking what the costs and labor estimates would be. If its in my budget it is something I might like to pursue later on in 2000(this isn't something I am planning on doing tomorrow). I'm mostly interested in the 2nd intercooler. I would love for it to be a cheap upgrade since the mounting for it already exists, but I have a feeling it will be a really $$ one that won't add much power but will allow the engine to handle higher hp/torque figures. Obviously the K04 and 2nd intercooler would go hand in hand, BUT I don't think the A4's running K04's have 2 intercoolers, so I'm really interested in seeing what its price vs. performace is. I am 90% sure in order to break my current planned top end of 220hp,285ft/lbs.(via Garrett's lastest version chip and a borla exhaust) I would have to go K04/2nd intercooler, and I am still researching if new fuel injectors would be needed, I know that new spark plugs would be.

Also this "Extrude Honed exhaust manifold" is offered as something to upgrade with a K04 "kit" it adds on another few $$ and I'm not sure what the benefits would be. I'll stay in touch with Todd and if an opportunity comes up, maybe I can pioneer this for the forum and give feedback, but I have a feeling that someone with more money than myself will or has already beat me to it

Time will tell....

but what do I know?

Good luck on your project.
