Alloy turbo head?
Turbo Mini Forums

Would a head like this [/url] be good for turbo charging if you enlarged the combustion chambers for the right compression ratio (allready "stage 3"). Works out at about £650 for the head, must be easier to work with being aluminium and for conducting heat?

It's only running the standard 33mm inlet, so depending on your intended power output it may not be the most suitable. They also do a 7 port version at a very similar price, worth a look !

My next project will be starting September at best, was wondering if anyone had used one.

Also that company look pretty cheap do 7 ports as well. Think you get a discount if you go direct shame the exchange rate is so bad.

7 port isn't that much more but you would need 2 webers or ITB's instead of a hif44 and a custom plenum.

It's a Pierce manifolds head.

Mine was prepared by MED and has 36/30 valves.

Ports are huge. Fettled it today ready for fitting tomorrow.

this is still a 5 port and will make no further gains over the original cast one correctley modded for turb application

which we have seen results over 250 bhp +

So go for the 7 port or standard head.

Specialist components do manifold kits for several 7 port heads to allow you to run injection.

This head will make as much power as a 7 port up to 7000rpm. In fact it will make considerably more with the right manifolds :)

I'm really curious to see how close your simulations were and I'm sure you are too.

i looked at one of them at a L2B run some years ago because i was thinking it would be good for removing heat

Minivanless, but reluctantly happy living with the decision. There'll be another one day.

I must add that there are probably better iron heads out there. This one just flows well enough "as-cast".

Could a little fettling from one of our resident head experts improve the flow of this head significantly Paul or are the ports very close to the jackets as cast?

If something is worth doing, it's worth doing half of.

I'm sure that they could make some improvements, not sure whether they would be significant.

The trick is to improve the flow by minimising pressure loss but without reducing the velocity.

Maybe get it done for next year. It's about to be bolted on the engine.
