6cm turbine housing on a 20g tdo5?

[chanley talon]

I was wondering if adding a 6cm turbine housing to a 20g tdo5 would increase the spool time of my 20g. It may sound strange but i would just like to get more torque down low. It spools around 3800 rpm now. I was wondering if i would notice a huge horspower drop or maybe just a trade off of torque vs hp?

I think you would get a fast spool but hit the wall in the upper rpms quicker. You'll also probably end up with a pretty serious spike.

You'll probably get a bit of

3800 is great for a TD05H 20G.....right where it should be. I don't see why you'd want to choke the turbine flow and risk getting surge out the ass depending on your boost level just to gain a few hundred RPMs of spool.

I think its actually just a weak wastegate actuator. What do you think about these?

I was looking at these 17 psi and 22 psi wastegates on ebay has anyone had any succsess with them?

Turbo Actuator DSM 1G EVO 1~3 VR-4 TD05H 14B 16G 22 psi | eBay

My boost jumps to 23 24 and by third gear 6000 rpm i am only pushin 15psi!
Will this help me?
