Just read this entire post....Anyone considering this kit, walk away....Its junk....Your better off buying a good used 993tt engine...It will be cheaper in the long run.
A customer(new) of mine had another Porsche shop install this kit with poor results...In less than a year he went through numermous headaches...End result??? Cracked #2 barrel, cylinders 3/4 had broken rings, major "shuffle-ing" of the heads/barrels(Heads had to be machined due to the severe pitting)...etc.
Good news? Well, once I'm done its going to be a 3.8l monster! This time, done right. If anyone is interested I'll post some pics.

Here are a couple shots of the engine before re-installing it in the car. Custom 3.8 P/C's, R&R rods, modified heads...etc
My appologies to whomever out there I offended with my previous post...The previous shop is more to blame than the kit itself...But for $14,000 there are (in my opinion) better options.

Some of the damaged parts..
Here are some of the damaged parts...
This does not include the broken rings, damaged turbos....
Its a long story to what happened with this car....I'll keep it brief.
----This is what happened before I saw the car---
-Started as low mileage 993
-Customer wanted more power...supercharger kits, turbos, swap engines...
-Shop told customer "we've installed dozens..."
-Shop tore engine down to rods, changed out bearings, rings, sent out heads for valve job etc....
-Shop re-installed engine etc...
-Customer wanted to put chassis on dyno to see what it makes...
-Shop told customer "Cars blow up on the dyno?!?!"...c'mon
-No boost gauge, no wide band testing....nothing.
-Customer complained about poor power....Re-sent out ECU a half dozen times, each time it was worse..
-In less than a year the engine started to leak oil, was told the base gaskets were leaking....
-I got the car, did a quick leakdown and boro-scoped cyl #2....see pic.
-I pulled the engine out, tore engine (cyl 1-3) halfway down and found the barrel cracked(cyl #2), cyl #3 (broken rings), heads severely pitted(shuffling), etc..
-Sent heads out....They needed all new valves, exhaust guides, etc. All 6 heads were installed on a billet steel jig to machine the decks..
-The list goes on....
---This is where I'm at now---
-Need to reconfigure the exhaust(looking for stock 993tt manifolds), boost piping has to be re-done(see pic, I don't why the pipes are made out of a million sections(also the welding is very poor, there is a TON of slag inside the piping), for some reason his kit never had any diverter valves installed??, new intake piping and finally a proper tune...
Does anyone out there that has one of the kits have had their exhaust done this way??? And it runs?? Anyone looking for stock 993 manifolds/stock cats??
Also need to replace the injectors...

Just to be clear, I don't even care about Protomotive's reputation since I don't even own this kit anymore. But trashing somebody's business with little basis is a pretty lousy thing to do.
p.s. Protomotive typically installs their blow-off valves (diverter valves) directly on the intercooler in the rear. Surely this system had them.

Junk? Maybe harsh on my part, but my own opinion....Maybe my standards are too high, but for a kit with a very high price tag, which includes boost piping made out of mutliple "cut off" pieces(poor welding/fab work), a couple turbos, intercooler, braided oil lines, etc...where's the 14K?? plus install?
Like I said before, I'm sorry for whomever i offended, but I would look into other options...
incompetent? What happened to your install? Have a good one "the other eric"....hopefully one day we cross paths...

I am resurrecting this thread since I bought a catch can. As some of you may know, I overfilled my engine which resulted in a fire.
My catch can is similar to the one in post 8.
Why did your homemade catch can fail? It didnt have a breather on top?

I know what hydraulic lock is and the consequences, but how did the oil get in there while the engine was running and how did it get in there without burning off unless it was poured into an intake at a high rate?
Just curious.

As a consumer, that is your right as it is anybody's.
I just bought a fire extinguisher mount and was disappointed with burn-through at one of the welds. Its one of the reasons why I prefer to fabricate things myself over buying things ready made.
