Better wastegate actuator ??


Recommended Posts

I clicked on a link on a dsm site and this came up. Having troble with the link. Try this one. and search some.

Apparently it is adjustable by changing the springs.

 

I have been considering trying the T3 confirmation of this actuator. My current turbo is a sy/ty t3 20g. It is difficult to make a starion actuator work with the td06 style compressor covers. The main thing holding me back besides the lack of money, is that the compressor discharge ends up where the actuator may need to be.

 

Just thought i would post it up as boost control is a important part of tuning. Boost spike plays havoc with our mas air sensors systems.

I was in the same boat as you a while ago, 10 years back to be exact. A red 87 TBI car with an 06 20g. I ended up using an actuator from a 1980's Svo Mustang.

A 3/8 aluminum plate/adapter bracket was cut drilled and tapped to mount the actautor It held more than stock boost, don't remember the exact amount 14-15 psi I think.

 

Here's an MHI 19c TD06 mounted to a motor I built. Even though it was a TD06 turbine housing, the location of wastegate flapper valve, swing arm was alsmost the same as 12a Td05's

An actuator from a FUSO truck or others that use MHI(mitsubishi heavy industries) should be similar to the one shown in PIC^^^ and can be mounted with a little fab work. It would be better suited for the level of boost your TBI beast pumps out

I actually have a aftermarket surge ported cover. This is a mock up picture. The starquest actuator does not have enouth travel to open the gate fully either.

Very nice Like the idea, the stock WG doesnt have alot of movement and is pretty easy pull on so either using a new wg, or adding sprigns and allowing the full movment of the wg is great idea. altho external would be even better!

Wastegate actuators found on Diesel turbocharger tend to have more arm travel than ones on EFI turbo application. A Holset hx35 wastegate actuator should have a good amount of arm travel and stiffer diaphram/spring. They are a dime a dozen. Edited by DieHARDmitsu.

I am interested in this as well. Don't think your link worked as intended.

Try this one. It shows a bolt on adjustable actuator for a starquest turbo. They have many styles of brackets and rods using this actuator.

Just curious, where is the actuator hose hooked up to on your car?

A nipple on the discharge. My 18g cover had the nipple at the beginning of the volute like your 19c. There is lower pressure at that point. I have tried various points.

shorting the waste gate arm anchor point will increase travel on the oem controller

True, but it may make it to sensitive and perhaps be difficult to undo. Now an adjustable pivot point could be useful.
