I was reading through the thread and was going to weigh in anyway, though looks like you're very much on the page I am reading from - so I'll +1 with with a bit more anecdotal evidence to support it

The ATR28SS15 would be a perfect turbo for your application. I didn't look into some thing even smaller as it doesn't make that much of a difference in response but did loses quite a lot of power. I'

^ lol... maybe I'll use a 3" intake pipe and add in more bends.. that usually gets the suuuuuuuuuuuuuuuutuuututuutut going LOL. Anyhow, some real world facts to back up the results.. errbody likes ti

What are your intake temps? if you're hitting over 60, time for a new FMIC. You'll be surprised at the power gain to be had with decent IATs.

What is the best way to check intake temps Johnny?

I used a thin 1.5mm thick K thermocouple between a hose and the fmic with the sensing part around the middle of the flow. Plug it to an egt gauge and you have a reasonably accurate iat reading.

 

I made a measurement on my car last year and with 30℃ ambient temp the iat rose to 43℃ near the limiter in fourth.

either buy a compatible IAT sensor and weld it on the cold side of your IC (never install it into your plenum like the OEM 32/33 GTR as it heat soaks) and run it back to your ECU or just a basic gauge on eBay with an open sensor (probably wrong term used) ie fast sensor not the solid ones that react slow similar to your oil/water sensor

Just for the record the IC Tao uses is shown in P550 of this thread . I didn't go back far enough initially but chased a link to it from elsewhere .

I'll be ordering one Monday and looking into the 100 C cat as well .

Also my IAT sensor is in the back of my cast X over pipe and I'm wondering if it is heat soaking because of it .

Iat sensor is fine there. I have mine there and it only heat soaks if the engine is off. Doesn't take long to go back to normal once driving.

I'll have to take some logs next weekend. Mine is on the cold side right behind the radiator and it heat soaks incredibly bad.
If you turn the car off and come back a few minutes later and go to drive it feels like its around 60+deg and for me thats around -5 deg timing. It takes a long non stop drive for the power to come back slowly. Even though the sensor has an insulation seal, it doesn't stop the radiator heat from soaking into the sensor itself.

I will be moving it to the chassis rails section of the ic.

Hi, we can supply a donor turbo for $150 so you will not need to send one in. The cost to high flow is $850 for G2 that is made for stock ecu and fuel system, while the upsized G3 cost $900, that supports around 260rwkws on P98 fuel, but will require a custom tune and bigger injectors to work. postage to Okinawa is about $150. Oil line is included in price quoted.

The tune should be checked either way.  VCT changes both the engine VE and the build of cylinder pressure, which means timing and fuelling requirements will change with versus without VCT engaged.

Hey guys.

Just wondering who here has experience with the standard "G2" high flow and what your real world results were?

Cheers!

I'll be honest with you, if you go through the efforts of removing the stock turbo to replace, you might as well go for something that's going to be of a decent size.

Thanks for the reply dude.

I was thinking the same thing, and therefore I wanted to go G3, but my understanding is the wastegate for this is set to 18psi. I'm hearing conflicting things that this might be too much boost for my 209xxx km engine (despite being well maintained, 200k service, etc)

Happy to hear opinions. Supporting mods: NISTune, Z32AFM,3in Turbo back + high flow cat, Walbro 255, 550cc injectors.

Goal was originally 240rwkw but am happy to temper expectations based on reliability.

      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

      A31 is pretty much the same thing without HiAIDS I mean CAS, no improvement lol. Not to late to send it.

      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.
