Where a car has two turbos listed, the top turbo is standard, the second was an optional extra.
I'm confident that the materials, turbo codes and models are accurate, but some of the serial numbers have conflicting information from various sources, so the VII and later serial numbers may be a bit jumbled. I'm not sure what the serial number is for the VII GT-A turbo?
Sorry if this has been covered before but does anyone know why Mitsubishi moved away from the 10.5 hotside on Evo vii and viii and then back to it on the viii mr and beyond?
From memory the stated purpose of dropping to the 9.8T hotside was to increase the response of the turbo (less lag, lower boost threshold) and the move back to the 10.5T was to increase top end power.
If you read the official brochures (you can download from the MLR homepage) for the Evo VII and VIII MR I'm sure they'll have some explanations there about the changes to the turbos and why.
Note that the VI and VIII MR turbo have different serial numbers, this suggests to me that, although they may be the same size and materials, there may be other small differences.
I've been told that my turbo on my 8MR is actually an Evo 6 turbo. The actuator gave it away!
I've got a OD 80 Series bb core one for mine also waiting to go on . Interested to see how the car drives once mapped, not expecting a great difference but still looking forward!
I found once I fitted my VII Stubby (along with an HKS hardpipe induction and the ralliart intercooler pipes) the throttle response was improved even more than standard (it's brilliant anyway compared to most cars) and the power delivery was smoother over all. Oh and spooled up approx 250-500prm earlier but runs out of puff by the same margin. No bad thing not over-revving the engine imo.
All 8MRs should of only came out of the factory in the HRA variant, the HR unit are pants.....its the only one to have for point and squirt boost :smthumbup
Yeah albeit a 10.5T version not the 9.8T that it states. Bloke is trying to pull wool over my eyes. He says its come off an e9. If it has, then its had a slower turbo put on it lol
I stumbled upon this, might be of interest to some.
I had assumed the very popular 80 series turbo was larger than others, but the wheel sizes seem identical.
Is the improved performance down to a better compressor wheel design??
The compressor size is denoted in the turbo model number immediately before the "G".
So, as far as I'm aware, the 80 series has the 16G6C compressor side, which is the same compressor wheel as the earlier models with the 16G6 compressor.
The 16G6C part denotes that the compressor housing has been enlarged on the 80 series.
Does the C not designate a different style of the compressor blades ?
