Hello Miataturbo people,

This is my very first post I have made on the internet so forgive me for any noobish stuff.

Okay, This is my current project in progress and it is obvious what I am creating. This is a 1.8 mk1 engine with a homemade manifold and with Garrett t28 ball bearing attached to it. I have also machined my cam cover to give me exposed cam gear. I will be creating a custom inlet manifold over the next few weeks. More posts to come. I hope you like the pictures and would like to hear what you have to say.

 

'dat tilt.

Why keep the power steering?

 

Yea.. It looks a bit extreme! I will be running a 3" pipe from turbo back, I did not want to use a tight 90 degree bend at the turbo so i decided to go down the tiltly turbo route.

I work on classic and vintage vehicles with no power steering, and this will be a daily driver so i want a small bit of comfort of power steering while driving..

 

I'm all for keeping power steering.

...but that angle looks a bit extreme. hope you don't toast the turbo or the rear seal like that

 

Yea, me too, this is a bit of an experiment... the oil will be under pressure so it 'should' be fine. I will soon find out when I run the engine.

 

Garrett has a .pdf floating around that specifically list turbo angles(? not quite sure how to word that) and what the limits are for the CHRA to allow proper oil flow/draining. IIRC they want you to have a slight tilt, but it's not necessary for longevity. No idea about your tilt, though.

Can't wait to see the downpipe and dump tube routing.

 

I remember there being a thread exactly about that here. Maybe not tilting, but rotation of the CHRA. I remember it getting pretty shitty a page or two in.

I'm all for trying it out and we'll see what happens.
OP please report back with data if it fails. In the name of science.

Looking good so far though!

 

Yea, I remember finding and reading that piece! I did follow it, but i may have added a couple more degrees and then with welding the manifold up the flange moved a little bit more... if it doesn't work and blows the turbo I will make up a flange to turbo tapered spacer that will level out the turbo, there is always a fix .... I will keep you posted, I can be the test dummy! I will hopefully have the engine up and running in June-July time.

 

Welcome, Cpt.Davos!

 

Welcome. Nice attention to detail. Now start working on a support to hold up and stabilize the turbo.
