Hi all
Curious if anyone here has an engine built by PMB that can give me a review on their
performance/reliability?
Going to need to split my case to replace lifters, and I don’t have the experience to do it myself confidently. Considering an upgrade from my 1.7 while engine is out, maybe a PMB 2056 build in the near future. I know they are great people, and do great work. Just wanted to see if any of you are running something from them so I can learn more.

Also open to any other recommendations on engine rebuild shops or anything else. Located in SF Bay.
Cheers

I have one of the PMB 2.3i engines in my car and I love it.

It is not as highly strung as some other engines, trading some peak power for longevity. Then engine came turnkey with complete fuel injection (Holley Terminator X.) You take it out of the crate and install it in your car. There were a handful of wires that needed to get connected. But its run like a top!

Eric does not like them, but I do suggest a tuna can on the sump. If you are hammering curves, you can starve the engine of oil. Its not a fault of the PMB build - just a fact of life with a type4 engine. And with double the HP and torque on tap you can HAMMER some corners.

With the 2.3i you have about the same power as a stock 2.7 /6. 150-160hp.

The PMB engines are under constant development, and mine was an early one - #2 I think. In fact its mine that are on their website.

The big think is that you are not just buying an engine. You are buying a tuned engine with modern fuel injection set up ready to go in the crate.
