A creative way to clock a turbo

Turbotech7 · Post by **Turbotech7** » Mon Nov 26, 2007 1:37 am

i was wondering what most people did witht he wastegate actuator when they clocked thier turbo, external would be nice , i would hate to rip it off my talon for this and 2 the cheaper the better. Im trying to enter this vehicle in the 2008 challenge by GRM. So any crative ideas would be welcome no matter how off the wall it might be,the main stumbling block i hit this week is this.

Any healp would be greatly appreciated

If it were me, I would do the regular clock of the turbo and run a cheap O2 mounted wastegate. You could pick up a new 38mm eBay wastegate for $150 or less. Also, if you wanted to "cheat", you could run an EVOIII 16g and no one would be wiser. Don't forget that porting the stock DSM parts is one of the best "upgrades" you can make. And by running an O2 mounted wastegate, you can port the turbine housing more and not worry about erratic boost response, boost creep or any other issues like that.

Another option would be to only clock the compressor slightly to gain more room around the manifold and tweak the wastegate actuator slightly. You might gain enough room by clocking it so you can mount the top actuator hole in the lower compressor hole.

Evo 8 turbo AND manifold. Will need to space it out pretty far though with some long studs and flanges. Off the wall enough?

Or, if you're crafty, you can get a flange for $40 and tubing for under $70 and make a tough log manifold and go top mount out of the way of everything else.

well the choice of a TD05 housing is obvious for me i have a 14 B 16 g and a big 16 G under the steps, the big 16 G has held boost steady @ about 28.5 psi, so thats the least of my worry's( besides im not sure how that whole traction thing would apply here. if i could jam my HX40 and tial on there i would have but im not taking apart a good running car

i said good running and describe a dsm in the same sentence!!!!!

and im thinking of clocking the CHRA off the turbine side to make the oil lines run straight down and the coolant line go parallel, that SHOULD offset the compressor outlet enough and should flow oil fine because of the CHRA's orientation.

and the EVO's manifold would work, but if im not trying to get it within the $2008 target price with the vehicle and mods inclused i would shove the TSI's dsmlink, get another holset

and the rest i should have in house. thanks for the reply and keep them coming.

I just lengthened the actuator rod so that there was a small amount of preload on the WG. Worked fine when I had a 14b, then a 16g.

So I can see the 'want' for clocking a turbo for RWD applications but if I may be so bold as to ask a dumb question...what is the need to do so for say a mighty max truck? I can see how it would be nice to have the compressor side towards the front while the exhaust has an easy exit but then you would need to have a difference oil drain and water feed lines in addition to re-configuring your wastegate actuator. That and I really hate the ring clip that hold the compressor housing on. We've gone the rounds with easch other...

I dunno, is it a clearence issue with the engine mount? I do not have the motor in my truck yet to find out but I am curious.

I think the main purpose of turning the turbo 180 degrees is to make intake and intercooler plumbing much simpler. Also, the exhaust would have to run under the turbo in stock configuration. I still think the EVO turbo setup would work great if you can find one cheap enough. I can't imagine it being any more expensive used than a new 16g.
