Leaded Fuel is no longer available here in NSW, but I plan to use optimax and PULP anyway. I've got a jaycar LED kit which plugs into the Lambda (exhaust)sensor from most factory efi
cars, I've got a few sensors too, easily pocketed at the pick'n'pull wreckers.

Yep, no form of cooling, its the worst thing about suck-through setups. So I'll have to strictly limit how much boost I will use. I would like to try setup some sort of water spray
that is activated by a pressure switch.

Scott/James, I thouhgt the least back pressure in a turbo the better. eg none perfect. So the bigger the better but I would suggest 3" to be a waste of money and would go with the
2.5" mandrel also. If 3" normal bent was cheaper it would probably be the way to go.
I have seen many of those articles on the air/fule ratio meters but can't remember what sensors they use to trigger the system. If they use the oxygen sensors from factory cars as I
suspect, then I'm sure I read they don't last when exposed to leaded (super) fuel. What are you going to run in the car.
With a direct path from the turbo to inlet does that mean you are not using any form of cooling of the inlet charge.

Yeah, I'd love to get my turbo engine up to the sort of HP figures you've got.. I've got a definate weight advantage though, the 1000 coupe is only 660 kilos. What was
Andrew's best quarter mile time with your engine?

By the way, Is anyone else on the list going to the nissandatsun National show in Sheparton, On Easter long weekend? should be a big one!

James.

Good to hear James. That should give u a bit of get up and go!! The exhaust i would do a 2.5 mandrel bent system. I think 3" would be too large and would lack back pressure. Well 2.5"
mandrel is what im going to put on my 1200 and its only NA so it should be ok with the turbo. 2.25 i feel would be too small for sure. We can weld in a sensor nut on the dump pipe for u if
u need one aswell. Cant wait to give u a run in my 1200 :) It should interesting!! cya

Gday list,
I picked up my A series turbo setup today. It's a suck through setup with an IHI RB6 turbo (off a 2Litre mitsubishi Galant). The setup consists of a factory A15 exhaust manifold thats had a
turbo flange welded onto it, and the standard exhuast flange is welded shut. The inlet manifold has been made from scratch and looks like it should flow evenly, theres a 'U' shaped pipe that
connects the turbo to the inlet manifold. Theres a 1.5 inch English SU which mounts onto the front of the turbo. That probably wont make much sense until I upload some pictures of it. I
havent recieved the dump pipe yet, it was sent to me seperately. Can anyone recommend what size exhaust to run this setup on? I'm guessing either 2.25 - 2.5 inch ought to do it? What do you
reckon davo ?
I also want to get an exhaust sensor mounted (maybe in or near the dump pipe) so I can run one of those richlean LEDs.

thanks,
James.
