i have a t67 i believe with a 8cm exhaust housing and have not been able to find a larger one to suit, you people with td06's do you know the exhast wheel size to compare, mine it 60mm from memory. Im not sure what to do atm as it will spool up nice and early with very little lag but not sure how much it will kill the top end.

Im not sure if the T67 uses the TD06H or the TD06 turbine, or another again. I have often read/seen ppl refer to the TD06-25G as the same turbo as the T67-25G, but there could easily be subtle differences, hence the different designation

What size are you after Clint as i have a 10cm and come the end of the week will know whether i want to go smaller, so may be able to trial fit one anothers and see how they go. I may even like to try the 8cm to see if i make the same top end power but with better response...perhaps telling me that my head, valves (???? i duuno) are more of a restriction then the exhaust housing on an RB20.

i would like a 12cm but a 10 would be ok too, thats why i need to find out if the TD06 has the same exh wheel, the blokes at MTQ said it was bigger than a TD06 and they couldnt find anything suitable in the misubishi range.

My engine is being done on a engine dyno so i dont wont to change it once fitted, so if i cant find something suitable i will just use it, can always add some extra power with Nos for the strip.

i think the 8cm is just another way of saying ar.. type thing.. just find out what a 8cm, 10cm, 12cm is equal to and there is your answer.. 8cm mite be .6 or something??? have a look at the ihi rx6 turbo.. very small exhaust housing but huge comp cover.. spools up at like 2800-3200 on sr20 but still packs enough for 300rwkw+ mite the same deal with your t67 with 8cm housing..

Dotn Apexi use a different convention again?

They typically have a P in front of their housing size referecne, which i think is the A/R in mm^2/mm, where as Garret use in^2/in so a Garret 0.87 equates to about the Apexi P22.

So how that helps me work out the Trust 8, 10, 12, 16 cm^2 housings i dont know ...anybody?

    • Hi,  Just joined the forum so I could share my "fix" of this problem. Might be of use to someone. Had the same hunting at idle issue on my V36 with VQ35HR engine after swapping the engine because the original one got overheated.  While changing the engine I made the mistake of cleaning the throttle bodies and tried all the tricks i could find to do a throttle relearn with no luck. Gave in and took it to a shop and they couldn't sort it. Then took it to my local Nissan dealership and they couldn't get it to idle properly. They said I'd need to replace the throttle bodies and the ecu probably costing more than the car is worth. So I had the idea of replacing the carbon I cleaned out with a thin layer of super glue and it's back to normal idle now. Bit rough but saved the car from the wreckers 🤣
    • After my last update, I went ahead with cleaning and restoring the entire fuel system. This included removing the tank and cleaning it with the Beyond Balistics solution, power washing it multiple times, drying it thoroughly, rinsing with IPA, drying again with heat gun and compressed air. Also, cleaning out the lines, fuel rail, and replacing the fuel pump with an OEM-style one. During the cleaning process, I replaced several hoses - including the breather hose on the fuel tank, which turned out to be the cause of the earlier fuel leak. This is what the old fuel filter looked like: Fuel tank before cleaning: Dirty Fuel Tank.mp4   Fuel tank after cleaning (some staining remains): Clean Fuel Tank.mp4 Both the OEM 270cc and new DeatschWerks 550cc injectors were cleaned professionally by a shop. Before reassembling everything, I tested the fuel flow by running the pump output into a container at the fuel filter location - flow looked good. I then fitted the new fuel filter and reassembled the rest of the system. Fuel Flow Test.mp4 Test 1 - 550cc injectors Ran the new fuel pump with its supplied diagonal strainer (different from OEM’s flat strainer) and my 550cc injectors using the same resized-injector map I had successfully used before. At first, it idled roughly and stalled when I applied throttle. Checked the spark plugs and found that they were fouled with carbon (likely from the earlier overly rich running when the injectors were clogged). After cleaning the plugs, the car started fine. However, it would only idle for 30–60 seconds before stalling, and while driving it would feel like a “fuel cut” after a few seconds - though it wouldn’t fully stall. Test 2 – Strainer swap Suspecting the diagonal strainer might not be reaching the tank bottom, I swapped it for the original flat strainer and filled the tank with ~45L of fuel. The issue persisted exactly the same. Test 3 – OEM injectors To eliminate tuning variables, I reinstalled the OEM 270cc injectors and reverted to the original map. Cleaned the spark plugs again just in-case. The stalling and “fuel cut” still remained.   At this stage, I suspect an intermittent power or connection fault at the fuel pump hanger, caused during the cleaning process. This has led me to look into getting Frenchy’s fuel hanger and replacing the unit entirely. TL;DR: Cleaned and restored the fuel system (tank, lines, rail, pump). Tested 550cc injectors with the same resized-injector map as before, but the car stalls at idle and experiences what feels like “fuel cut” after a few seconds of driving. Swapped back to OEM injectors with original map to rule out tuning, but the issue persists. Now suspecting an intermittent power or connection fault at the fuel pump hanger, possibly cause by the cleaning process.  
    • For race cars, this is one part where I find having the roll cage bar having gone through a hole in the floor better than the build it up on a ledge inside... The Merc I help on, the main hoop ends are marked on the car, and the jack is marked... Jack goes under a few inches and lifts one whole side of the car up... Removes that fight for long slim jacks for race car duties!   My biggest issue for the daily drivers I work on, is my jacks don't go high enough. The jacks start out on a few blocks, jack it up, then start a second jack under it on more blocks, and then I can get an axle stand under it. My axle stands are presently in use, and are nearly fully extended. The car is sitting with barely more than a cm of clearance to get the wheel off the studs! Sarah's Kluger is the same, as it has an ungodly amount of droop available in the suspension and a distinct lack of good jacking points!
    • Happy? Yep, my to do list is getting shorter and shorter. Either this light approaching is the end of the tunnel, or I'm about to be hit by a train... Ha ha ha   Also, Duncan isn't that far out of town that you need to make a multi day drive out of it. 😛
