PWR if you're rich, superb coolers OR Koyo, just works.

I would avoid that brand that's big in America and looks like rebranded eBay radiators with flashy marketing.

who might that be??

55mm Crossflow is what I got went from 42mm (i think) typical koyo

koyo was fine but started to struggle on my setup as I pushed it harder - above cooler change has done the job well since no probs

I've got a cross flow in mine from Race Radiators, it's a twin pass 55mm core. It was a fair bit more than a PWR but has a swirl pot and a few other things I wanted which you can't get off the shelf.

He's the Victorian agent for PWR and does their warranty stuff, he doesn't use their cores.

It's a nice bit of gear, probably overkill but you know how it is

No idea if lever is better or worse, I've only every used the push down screw cap ones.

I run 1.3 bar cap on the race car and have got >130o coolant without blowing anything, not really recommended as best practice. Of course if you go higher pressure cap it is worth changing all water hoses to silicone and good hose clamps instead of the factory clips

(personal opinion) I prefer to run a 1.0 to 1.1 bar radiator cap, FWIW with my 1st motor (stock), I had a 1.1bar radiator cap using an off the shelf 42mm PWR radiator and the car was thrashed and cooled down for a good 10 laps on a near 40 degree day at Wakefield Park.

Water temp never went past 120 C (from memory) and no coolant was gurgling, albeit it did have a 25 row Setrab oil cooler. I even used the A/C on cool down laps lol.

      Misfire/stalling issues

      By Chris_Guthrie · Posted

      Any recommendations on a decent replacement manifold that doesnt break the bank or require additional mods for the stock turbo setup? I figure if I'm going to pull the manifold off anyway to fix the studs might as well replace it.

      Misfire/stalling issues

      By Chris_Guthrie · Posted

      So I checked the turbo out today. Very minimum play at all just enough for the oil to take up when it's running. I did find an exhaust leak at the manifold. 1 stud all the way in the front is missing and the one all the way in the back is broken off. Front has visible signs of an exhaust leak. I'll fix that soon but that's not my problem still.  I also found that the nipple coming off the turbo had the hose capped off and a hose ran from the j-pipe by the bov going to the wastegate. I removed that hose and capped that nipple and put the turbo nipple hose back on the wastegate.  There was a ton of oil residue all through the charge side of the intercooler piping going to the throttle bodg. I'm thinking that's from the pcv. Doesn't seem to be coming from the turbo that was all clean on the pipes side.  Haven't had a chance to check fuel pressure yet, haven't had time been having to pull a lot of doubles at work. I did pick up some carb cleaner to clean the iacv but wanted to make sure I had a fresh gasket in case the old one rips when I pull it off.  I'm waiting on a MAF that was supposed to be here today but delayed to Monday. Have a double Monday and Friday and work all of next weekend so going to try to find some time in the middle of the week to try that out. Did about a 10m trip around the block today and towards the end the issues were coming back. Fingers crossed on this MAF but if not just going to throw a fuel pressure gauge in and see where I'm at.  Did notice today that I can definitely hear the injectors pulsing. Very audible clicking coming from them. Assuming that's normal? Should also mean CAS is functioning somewhat properly. After it warmed up when I started it the intermittent misfires came in again. Did start doing that before it was fully warmed up.

      This morning I carefully reinstalled the manifold and started looking at a couple of things I need to do.  Heat wrap arrived sometime today so I popped into the shed with the missus dishwashing gloves and started wrapping the first half of the dump and the screamer/plumb back.  Once I do the second half I'll be able to final fit the turbo and exhaust up.  Also pulled the harness out today and started terminating it at the ECU end. A connector is done, just need to run the remaining wires that arent in the harness - 12v, gnd and couple I/O

      Thanks for all the replies! I also wanted to ask if wheels that were fitted on Ford Falcons would fit the 350GTs as well? In the area I'm at there aren't that many options for secondhand wheels and new ones here are way out of my budget. From what I've seen, most of the wheels that are available that were fitted on Ford Falcons have an offset of +33 to +36, with a centre bore of 70.5mm whereas the stock 350GT's ones are 66mm, can't seem to find any hubcentric rings that fit that difference though.
