Holset install

[camboscams]

So a Rotella T6 5w-40 would work well? Its pretty well priced where i'm at.

T6 5w40 is a great choice for these engines. Good cold starting ability, excellent lubricating properties and stable at high temperatures.

Awesome thanks for everyones input. Hopefully this will remedy my high pressure issues and keep the holset happy. I won't be able to get as much done on it as i wanted this weekend but i will give an update either way.

I am also running an HE200WG.  Here's a pic of my WG actuator bracket...





This turbo helped my engine combo make BIG power and plenty of boost. (40+ psi and probably 200HP from a 1.5L)  As others have stated, getting the downpipe fabbed is a bit of work, but well worth it.  Alcaid provided an exhaust housing adapter that works with 3" exhaust tubing, "massaged" a little to fit.

Why does the waste gate actuator need to be modified? Is it just because of the positioning of the inlets/outlets required to mount it in a fwd engine bay?

[Jetmugg]

Yes, relocating the actuator was required in my application due to the need to "re-clock" the turbo.

Jetmugg, great looking adapter i think i will do something similar!

If making a bracket for the wastegate, you might consider fastening it to the exhaust side rather than the intake scroll.  That way, the intake scroll could be rotated without changing the wastegate bracket.

The center section was all I needed to move on mine.

Do you have any pictures of your installed setup theman53? I have looked but never seen anything.

[theman53]

yes in the middle of the build thread round 2 page 27 iirc, I just looked it up for someone not long ago. It isn't detailed but it shows the turbo on the car

Well i made some progress yesterday! I got the turbo reclocked and a new wastegate bracket made and mounted. It is very similar to yours jetmugg and i think it will work well. Next is the downpipe and and cold piping. I reused the -10an drain flange off of my vnt that i removed and just bought a -4an oil inlet that will reuse my old supply line so that is easy. I plan to fab an integrated air to water intercooler into the intake manifold but i may save that for phase two. For the time being i will run non intercooled for a while and i'm placing the order for some silicone fittings tonight from Frozen boost. My question now is does anyone have a good opinion for a permanent air intake? I have looked at donaldson filters but have not found one that will work well. I could always run some piping and slam a cone filter on it but those just don't scream good filtration to me... Does anyone have any suggestions? It is a mk1 rabbit if that helps.   

[theman53]

I did a K&N with a prefilter and built an air box out of lexan. If you don't put an air box around it you are making a hot air intake not a cold air intake.
Before you ask for pics again, they are in the build thread. I remember putting them in there...start where the new turbo is going on, I think page 24 or so.

Got a really good start on my downpipe this past weekend. Finished the exhaust flange and 2.5" v-band mount on the turbo side cut welded and cleaned up with the die grinder. By the time i got the flange and the vband flange mounted to the turbo things got really tight as far as routing my downpipe. My only other option was to get some stainless weld pipe style fittings and tig a really tight 120 bend, but i already had the mild steel exhaust piping so i went ahead and used that. I had to cut off tangent which i hate doing, to make the connection at the turbo but after that the rest came together really well it's still a pretty smooth transition so i feel good about it. I have an hour or so to make the final connection to my old exhaust and do the final welding so i am excited about that. After that all i have to do is cut a new piece of braided stainless drain line, and screw the oil feed in and the oil components are taken care of. My frozenboost order came in early so i have all the parts to take car of the air side of things so that shouldn't take much time. So depending on how well this weekend goes i may be able to drive it!

Do you get much flex in your bracket when applying pressure to the wastegate actuator JetMugg? Mine is 3/8" plate and it flexes a good bit before it finally opens the wastegate.
