Nice to find a stock, unmodified Coupe. I see only an aftermarket stereo (mounted under the dash) and upgraded speakers in the stock location

The current NFNR manifold looks a little different

On top are all manifold plenum taps. So vacuum when off boost
* MAP sensor would likely connect to one of the small fittings
* Brake booster to the large fitting on the end, or whatever else needs to see manifold pressure

Thanks very much appreciate the reply!

On an unrelated note I'm trying to remember what size the vacuum hose is in the top of the NFNR manifold there and on the end for the booster..

a basic catch can works with any manifold and with any carb or EFI. Unlike PCV which is tricky to run with most twin carby manifolds

connect both engine breathers to the catch can. That's all it takes. Rocker cover breather and block breather tube hook up to the catch can

There are more advanced oil separator cans that connect to the PCV fitting on the manifold. Instead, use a catch can with its own air filter

By the way, anyone got a picture of the NFNR Racing EFI manifold?

Well it depends on what you want

A racing cam means high-rpm power. Do you rev your A12 up to 6000 rpm now? If you never do, you won't like a racing cam. With racing cam, you will shift higher than 6000 rpm, where the stock A15 makes peak power

I would skip the extractors. Use a cast iron extractor (factory GX-style exhaust manifold) is quieter and makes just as much power at 6800 rpm. Plus more durable, last longer. Long-tube xtractors are only better if you tune them for a specific RPM range. Some just like the sound of tubular extractors

The stock ute 4.11 rear diff is a great compromise between quick acceleration and fuel economy. But if you have taller than stock 12" tyres, I would go with a steeper diff like a 4.375 or 4.675 from a Vanette in order to regain some acceleration

The other way people get the most out of an A15 is to put higher gear diff like a 3.7 or 3.45, keep the exhaust stock and fit taller tyres. This way it will get the most fuel economy, but the A15 will still accelerate as well as the A12 while getting better highway fuel economy. But then better than all that is a 5-speed overdrive

What do you hope to get out of it?

We have to run a catch can in NSW how did you plumb it with the nfnr manifold and efi setup please?
