locking n/a distributor to suit low boost turbo engine
Turbo Mini Forums

Hello! Right im currently in the mits of converting a 1275 a plus engine into a low boost turbo motor using the gt17 turbo. I woulx like to run around 10psi if not a little more if possible on standard 21268 pistons, as funds are tight id like to use a standard dizzy at the moment till I can afford megajolt setup, ive heard people talk about locking the dizzy at 24-25degrees? Can anyone please explain how I do this? :) ive also thought of using a metro turbo dizzy, would this be a simple change of the dizzy and fine on my set up? Thanks!

I can't help but have a feeling that I've read this before?

This is FORD country, on a quiet day you can hear Vauxhalls rusting.

It's the twilight zone !

9.85 @ 145mph
202mph standing mile
speed didn't kill me, but taxation probably will

anyway,

I wouldnt lock it, trying to start an engine on 20 od degree's is probably going to be a PITA,

Ok thanks joe :) Il leave that idea for now then, ive been offered a meteo turbo dizzy aswell, will this work ok with the gt17?
heres a picture of it

the std metty one will get you up and running, wont be optimum, but shouldnt be a million miles out.

Ok cheers joe. Great help

hi joe

what do you mean by going to be a pita ?

If you try to start an engine with too much advance it tends to kick. Your best bet is to look for a metro turbo dizzy, or just use a standard one to get you running, and back the timing off a little.

Hi matty. Really am impressed with your manifolds for the gt17 turbos. Ive been stripping the manifolds off my 998 ready to get the engine out and while they where off I had abit of a play with getting the gt17 down the back of the engine and possible manifold designs.... all i can say isI dont know how you have done it! Its so tight down there!

Just jumping in on this. I am considering fitting a Supercharger and am looking at what is needed. Have been advised to get a mappable ignition but make sure it is one with a trigger wheel. This is going to push the cost way up. I have a Metro electronic distributor so what are my options?

Just realised this thread is 7 years old, I’ll start a new one.
