why head from hgt?

Interesting!

Have you got some pics of the welded pipe for the external WG on the manifold?

Pitures and dyno?

HGT has bigger valves

because the head from hgt have bigest pipes of air
and the cam of inatke also

no i haven't
because i have still not finished
I have still make some thinks more
and other regulations
then i will post pics and dynograph

i like your front bumper,was it hard to do?

show pictures i love to see

show pictures i love to see

with the HGT head, are the turbo valves not sodium coated?

what had to be done to the HGt head/valves for it to be safe on the turbo?

Ry

i don't now what my engineer makes on
my coupe
but it work's very nice

what pictures you want to see precisely?

the engine

the engine

i don't have at that time
when i a have
i will post some fotos

Me too

I would like to know how you have fitted the external waste-gate on exhaust manifold (welded at 90° or 45° or different method)

Is the cylinder head a straight swap or do you need to change anything to make it work with rest of the engine?

Exhaust valves need to be replaced with sodium filed ones
But why stop at just the HGT? why not get a stilo 2.4 head does that flow more still?

i have change the standart hgt inlet manifold with 20vt inlet manifold
and it works very nice

Exhaust valves don't need to be replaced with sodium filed ones
is the same with 20vt exhaust valves

I did not change the head with stilo 2.4 because this head has bigger valves as for the draft

So oil and water channels in and out of the HGT head are the same as 20vt head?

Please add some pictures here so we can see the HGT head

Slightly off topic, what front brakes are they on your car?
