Default TD04 replacement?

Hello all,

Looking to replace my TD04 on my 2.0 ej205. Iím looking for something with similar spool time to the td04. I donít want extra lag and I still want a smooth power band. Iím pretty new to all of this so have mercy. What are some decent options? Has anybody had experience with making their td04 ball bearing or anything along those lines?

Thanks!

The amount of money it would cost to make the TD BB wouldn't be worth it. That turbo already spools fast and runs out of steam equally as fast.

Spool also has a lot to do with the other mods you have. I had a VF34 for a couple years and it spooled almost as fast as the TD but carried a lot further. However, I had done a lot to help it spool faster.

So, what other mods do you have or are planning on doing?

There is no option. Turbos are like seesaws....want quick spool? Go small. Want big power go big. You can't have it both ways. Bigger = tuning, fuel pump, injectors and turbo.

Early 2000s JDM Spec C STi.

Here's the thing. If you want to look into a bigger turbo, then you have to be willing to make compromises and prepare yourself for the rabbit hole you're about to go down.

One compromise is changing the way you drive. You can compensate for spool by down shifting more often. That's where I am with my 20g. I sacrificed a little spool for a broader power band. I'm still training my habits but I've only had it on the car for a week so pretty soon I won't be thinking about it, it'll just be muscle memory.

Another compromise is money. You can get a VFxx or 16g size turbo to spool pretty quick on the USDM 205, but it's going to cost money. It won't be TD04 quick, but can be within a few hundred RPM. Depending on the mileage of your engine you may want to start thinking of getting something that has AVCS. It makes a noticeable difference. But either way I'd recommend the following to help with spool:
-Very very good tuner and do everything they tell you
-Wrap and ceramic coat all exhaust parts from exhaust manifold to down pipe
-Turbo inlet. Your OEM one will tear if it hasn't already. Killer B is possibly making a hard inlet soon. I'd contact them as another person who would want one. If they do make them, I will be swapping my Perrin inlet for theirs
-Turbo blanket
-Large core TMIC
-Adjust your driving habits

In for the advice, as I'm sure I'll end up in the same boat eventually. Reading old TD04 threads now......
