With all this talk of turbo type-4 engines, I am getting excited to finally get my together. This is a preview picture of it mounted in the back on my car. I am not going to show you more right now because we are redesigning the exhaust system to get more ground clearance and we are still working on the intake side of things. It is all going to be covered up by an intercooler anyway.
In either case, if I planned to run only up to about 12psi boost (guessing) would a 2bar MAP sensor be sufficient or should I just get a 3bar sensor? Is there a downside of using a 3bar sensor and not going about 14psi? Any resolution issues or anything? Also, are there preferred brands?
Thanks,
Britain

Here is a better picture of the turbo...

no clue on the map sensor....but are you going to run any engine tin?

I had planned to, but I am not sure now. The header and everything is ceramic coated and shouldn't get too hot.
I had a set of stock 912E tin that I might cut up to fit...don't tell any of the 912E guys though (it is big money).

Which ECU do you plan to run? That makes a significant difference, as they can't all be used with whatever sensor you like. FWIW, the Megasquirt stuff comes ONLY with a 2.5bar sensor, as it provides good enough resolution for NA applications, and will take you up to 21psi of boost, which is usually enough to blow up most engines.
If the ECU you choose allows a lot of latitude, a 2 bar sensor is fine. A 3 bar sensor is also fine, as the resolution loss is, in practice, a non-issue.
On tin, I think Jake is working out (or has available) fiberglass 912E "tin". I'd use that to cut up for the turbo long before I cut up real 912E tin.

I am running Electromotive TEC-3 system for my car which will take GM sensors. I will just go ahead and run the 3bar but I don't think I will ever get into that range. I didn't know about the 2.5bar...who makes those?
As for the engine tin, I will need mostly custom pieces to fit around the engine mount bar and the turbo. I will keep the cutting to a minimun if I do choose to use it.
