Hi started a thread in the engine build up but now have gone the turbo route. I have recently bought a Pulsar PSR3071R turbo link can be found here if interested https://www.pulsarturbo.com.au/products ... e3b6&_ss=r, a 44mm waste gate and a manifold from a guy that hand builds them here in Australia. Also bought a complete ignition setup by ICE https://www.iceignition.com/products/ch ... 561b&_ss=r that I think will make life easier. I have 60 thou over speed pro cast pistons, arp bolts and head studs, head will be cleaned up in the ports and using hughes oversize valves, crow cams lifters and valves springs with speed pro push rods. Will be running a rollmaster CS5300 double row timing chain and romac RO0224SA balancer. Will be using a beefed up 904,extra clutches and transgo shift kit with an approx 2,600-2,800 stall converter and the rear end will be an 9 inch as I already have it in another valiant that I'm converting back to stock. It has 3.7 gears, lsd and a few other good bits in it. All this will be going into my 1965 ap6 valiant which weighs in about 2758 lb. Have on order a autometer air/fuel wideband setup and already have a holley boost referenced regulator. Now that I am going turbo my issue is what cam to run and manifold/carb to use as I have a aussiespeed hurricane 4 barrel manifold already or should I be looking at going 2 barrel setup. Ant help would be greatly appriciated. Thanks Steve

Bit of a small turbo for a slant... is this a 225 or a 170?

That is one expensive way to get a boost timing retard, but it will get things done.

I'm running a similar engine combination minus the oversized valves and stall converter, and I'm using a Comp 264S cam. The price was right. There are better cams in the 264 advertised duration / 0.440" lift out there range now.

When it comes to turbocharged street cars, my own view is that there's no carburetor like no carburetor - EFI is a lot more tunable. (If this is intended to be a drag car, setting up a carb may be a bit easier.) Some others who are better with carbs may chime in if you want to go that route.

Thanks Matt for the heads up on your cam choice. Its a 225 that I am building, not sure but I may be corrected, we never had the 170 here in Australia. Main reason going for carb is I picked up a new 500 holley recently for a really good price $600 opposed to them normally $1200 and a friend of mine has a holley 600 that I can pick up pretty cheap. Going fuel injection that I have looked into is going to cost between $4000-$4500 in the end and just dont have that money yet but possibly in time may go injection. The cam I have for it is a viper cam bought through hemi performance here in Australia and the specs are .287 duration on the inlet and exhaust, inlet .243 and exhaust .240 @ 50 with a lobe centreline .113 on the inlet and .111 on exhaust with a valve lift of .481 on the inlet and .478 on the exhaust. Rpm range is 950- 5300. Just not sure if this cam will work with the turbo setup.

Really? Wow!

That's a more aggressive cam; I would either use less cam or a bigger turbo. The 3071 size, assuming it's a duplicate of a Garrett, is more of something I'd pair with a stock cam.

The carb is going to need a lot of mods for boost, more than a simple rejetting if you want decent drivability.

From what I remember, even people making big power with a turbo are using near stock cams. Nothing real exotic.

Yes, too much cam for a turbo. It will shift your RPM range up too high for what a 225 can rev. Here's a good one: https://www.jegs.com/i/Howards-Cams/466 ... a-EALw_wcB

I have done turbo and supercharger and I would not mess with a carburetor. That is some coin for EFI, though...

Sounds like fun,
Lou

Hi thanks for the comments and recommendations. Looking like I'm now more inclined on fuel injection than carb on the 225. Done some searching on the net and found a sniper 2 master kit for just under $3000 and they seem to have a more positive review than the first series. Being new to turbos just wondering where you guys are taking your oil feed line from as here in oz we have an oil filter remote setup and if the return goes back to the sump. Also being water cooled can I use the heater lines for the cooling set up. Here you can view a few pics of the setup I purchased. Cheers Steve

The Sniper 2 has two problems here. One, TBIs tend to have poor fuel distribution. Two, Holley only documents how to control timing with a Hyperspark distributor, which doesn't exist for the slant six. Aussiespeed makes multiport manifolds for the slant six; an entry level Haltech, Holley Terminator X, or an MS3Pro Mini (or even Microsquirt) would work well for running such a setup, and you don't need the ICE system for boost timing retard when using an EFI system with timing control.

Turbo oil return drains tend to be a bit frothy; it's often best if you can return them separately to the sump, above the oil level.
