Guys a little help if you would. Some of you may have seen my other thread about my broken GT3071R. I posted up a video of it here:
Well after speaking to some turbo specialists here in the UK I was asked to send in the product number found on the plaque on the center of the turbo.
Now I just googled the number, and it turns out it's a GT2871R and not a GT3071R as I was led to believe when I bought it used a few months ago.
Not all bad I guess - the GT2871R is a great turbo for a Miata right? Only the problem is that my turbo seems to have a different compressor housing than a 'normal' GT2871R. It has 0.5A/R stamped on it, which makes it huge like a GT3071R. The exhaust housing has 0.86 stamped on it.
So it seems I have a GT2871R with 0.5AR compressor and 0.86 exhaust housing.
I'm not a turbo expert so I'm not sure if this will be well suited to my goals. I plan to make around 400-420 flywheel horsepower.
So can someone help me ID this thing and tell me how it should perform? The intake measures 2.75". Here as some pictures of the actual turbo:
The code on the plaque reads:
I'm feeling pretty pissed off right now and it's been too long since I purchased the turbo to get anywhere with the original seller. If someone could tell me what this turbo should perform like that would be perfect.
I've never seen a GT2871R with this size compressor housing so don't know what it means.
