Doing some pre-planning for the first start of the turbo build and I am trying to make sure I cover all the "best practices" when attempting to start a carb turbo build for the first time. Would love some input from the pros!

So far I have:
- Confirm fuel pressure
- Plumb actuator without a bleed valve/boost controller
- Doublecheck all vacuum feeds, seals, and connections
- Validate oil pressure
- The base setting for the carb with BDD needle? (could use some input here)
- Ensure you have a safe base map on your ECU
- Ensure your timing is correct (if not using ECU) (could use input here on base timing to start)

Welcome to the forum,

fuel pressure to be set @ 4/5 psi at idle, check that fuel pressure rises with pressure applied to the reference on the fuel pressure reg' with a gauge installed between the reg' and carb.

If using a new cam and follows have a search for "knocking in procedures".

The BDD the was stock needle for the Metro turbo's, you'll be able to set idle mixture as normal but the profile of the needle may not be suited to your engine spec.
It should be ok for you to put miles on to run the engine in @ low boost. This really should be checked on a rolling road. Have a read http://www.turbominis.co.uk/forums/index.php?p=vt&tid=159683
A wide band / AFR gauge is a useful addition to your dash.

Re timing, the assumption here is your using the stock distributor? if so then timing set as per factory insuring the Vac' advance is functioning.
If nit using the stock item then the ignition advance curve may not be suited to your engine.

Hope this helps.

Shane

Hi Cole,

Mate the fact your asking soooo many std questions on fb and now here.... but you run a YouTube ch that brings an income, where you tell people how to do this stuff and build engines.

Is it just me that sees it as a little odd?

I have started posting on Instagram also my name on there is turbomk1mini

Nothing is impossible it just costs more and takes longer.
