been spending a bit of time on this whenever i get a chance, so far its mainy been parts chasing and designing how its all going to work, got a little bit of a start on it before my last swing.
specs
5L vt roller block
1.65 adjustable shaft mount roller rockers
permaseal 3 layer headgaskets
hydraulic roller comp cam
stock bottom end
flipped tb for reduced cooler pipe length
ARP headstuds
borgwarner s366 turbo .88 rear open
50mm turbosmart external gate
will be using link g4 ecu
building manifolds from 32nb runners 40nb crossover
bit of surface rust starting to appear, been 4 weeks since i touched it lol, turbo will be highmount where alternator usually sits, im making a bracket to relocate alt to where aircon is.
crossover is going to have to be around rear of engine under sump due to lack of room in VS bay

im thinking of changing cylinder 5 to make it shorter, might run it underneath like cylinder 7

ended up changing my design slightly

I got a bit more done today, i need to get a bit of ofcut 3mm m/s so i can fab up the merge under the turbo, the 40nb pipe is too small to simply use 2 bits of it

Nice work. How's your access to the plugs? Do you think you might have dramas frying leads?

Those loops seem big enough for access to plugs and leads.

Yeah plenty access to plugs. I'm going to get them hpc coated once they are finished along with the turbo housing.

Started welding it up finally lol. Been overseas n working on Torana aswell

Getting back into the swing of things with the tig. My caddy has been playing up tho. High frequency start not working for some reason and the slope down also is not working properly. We got fronius tigs at work which work fkn mint. So crappy coming home n using the cig haha

looks good mate. Make sure you get a nice smooth entry for the gasses to flow into the wastegate.

Looking good, are you going to run some sort of brace to take the weight of the Turbo?

Still unsure of I'm going to brace it. There are bloody sturdy.
Going to go thru with ms filler rod n smooth over all the entry/exit points by filling then smoothing out with a die grinder. Gate will be mounted under the turbo taking a feed from each bank and merging into a y piece then into external gate

I think where the 4 pipes merge into 1 it may crack after being heat cycled many times with that long pipe giving the turbo alot of leverage onto that join.

Welds look really nice tho, quite neat.

Is there room to the the exhaust from the back of the turbo out under the car without going through the guard? Thats the biggest problem I can see on my Torana... no where to put the exhaust after the turbo :(

Cheers. Yeah they not too bad considering I did it on my scratch start at home. Nah there won't be any room. It's all going into a vs engine bay so il have to cut a hole in guard. I got some 5mm flat bar there so il make a bracket to bolt onto the head
