No, for a number of various reasons.

1. To get big power from a T series you need forged internals and management
2. Everyone does it.
3. I prefer the 8 valve power delivery and the fact it costs bugger all to tune
and 4. Being such a rare car to fit a different engine would ruin some aspects of its originality.

I dont know of any T-16 Maestro's bar Andy Nicholls that is faster than my 8 valver, they may exist but

Very very nice examble my buddy squashed one of those engines in his mk1 fiesta it flys!!!!

A fantastic project and a great write up, nice one :thumb: Any chance that you can post your timing slip? We ask for dyno sheets to back up bhp and timing sheets for quarters to keep the site free of bullshit

Very nice car mate, always liked the Maestro Turbo. Used to have a Montego turbo tuned by Moto build, so i know how quick they are.
As you said the beauty of the old skool 8 valves is that it doesn't

What a great write up of your Maestro. That is a great achievement to be proud of - well done

I bet the performance surprises one or two people
