Turbo upgrade, which one.
« on: August 13, 2010, 07:56:10 pm »
My T3 is too small, time for a bigger one. I can peg my pyro gauge right now with the T3 while boost is at 30psi. That is with water injection.    Is there another bolt on or is it new exhaust manifold time with new turbo.  The engine is a 1.9aaz/1.6 block with a Giles built pump.  I am not thinking a vnt right now but maybe a HX35 from a dodge cummins.  I know I will have to make a flapper vavle for the divided housing.  What other turbos are a good candidate?

HX35 is big, even when flaps are used. There is no bigger bolt-ons available. I'd try to find HX30, Scwitzer S1BG or something that size. Ofcourse it depends what power range you are looking.

An HX35 is 3x too large for your engine.

The reason you can peg your pyrometer with 30PSI from the T3 is because the turbo is extremely inefficient at that pressure. Its actually flowing more air at 25psi than 30psi because of the difference in temperature!

Why don't I see more guys running small ball-bearing turbos that are efficient and spool rapidly instead of thinking about turbos from trucks with 6L motors? I will be running a turbo which is too big for my application but it was free and has the correct flange.

All ball bearing turbo's I've seen need coolant for cooling since oil flow is restricted because of the bearing design.  It wouldn't be too much of a big deal to run coolant lines to it but this adds complexity to the swap.  I personally love my vnt setup bolted up to an aaz exhaust manifold with the triangular flange.  Pulls hard at 20-22 psi.

Isn't the T3 too big for the 1.6 engine? Or does the gov. mod make it more reponsive quicker? I thought it would be more at home on the TDI?

Looks like I will lower the boost down a little right now. 

Gee-Bee,  Do you know how much boost the hybrid can push out before it becomes hot air? My pump is setup to run 30psi of boost so I would like to keep this new turbo in that range.

Do you know which S1BG turbo to get.  I found a source but there are like ten different models.   They range in $600 to $1000.  If you happen to know a model number that would be great.  Do you know which cars they came on?

Ok I have been looking around and I decided to go with a hx30.  Now where is the heck do I find one.  I looked high and low for an hx30 and it looks like no one sells one.  I have been on ebay germany, uk and usa with no luck.

If you want to spend a good amount of money you could try this:

He's had some issues with some of his early vnt hybrids though so there is a risk factor.

That turbo is about 500 more than I want to spend.  Who knows tho if I can't find a hx30 I might go that direction. 

Now that 997 looks like it would be way too much fun.  That car is a straight to jail ticket, do not pass go or collect $200.

I'm pretty sure his is white!!! I'm sure if you ask him nicely he will email you pictures  ;)

bugnut I'm still rocking a K14 I have been eyeing the VNT-17/22 hybrid, but they are like $1800. I'm thinking maybe I should just find another hairdryer and compound them. It seems like that would be the cheapest way to reduce lag and make tons of boost. Since you can fabricate I bet twins would be even cheaper for you.
