200hp-300hp Turbo Waterboxer is the US ready?

[MarkWard]

Traveling America, 1/4 mile at a time. You can get away with a lot when it only needs to hold together for a 1/4mile. Top fuel does a tear down between runs. Not saying you can't get the reliability, but 300 hp on a stock bottom end engineered to handle 100hp, decent drivability, decent mpg is ambitious.

Karl, I don’t know him personally. I’ve followed this thread and the injector thread with interest. I happened to notice member milrmic had 2 posts total as of this am. Both were tagged to the two threads I’ve been following.

I probably won’t be the first one in line to get a Covid vaccination either. 200 - 300 hp reliable with a wbx is ambitious. That’s all I’m really commenting on.

I was one of the early res ponders to this post. I bought a long block from Marco in 2017 in anticipation of the turbo kit. At 7,000 ft elevation a turbo is the way to go. If I don't sell the Doka before the kit comes out, I'll buy the kit and install it.
I think 200 h.p. will be adequate, but not neck snapping, tire burning performance. 300+ h.p. would be more entertaining .
A friend who builds racing Porsche & VW gear boxes states the trans will handle 200 h.p. with no issues. So unless you start doing high rpm launches and burn outs you should be fine.
To some point, the more power the less stain on the motor. In the Doka ('86 2.1), going up a hill on the freeway, the gas pedal is floored. I'm doing 60-65mph. That motor is working a lot harder than my 3.3 400+ h.p. turbo motor in my '68 crewcab.
Compared to the alternatives, Porsche 3.2, which are now way too expensive, a Subi, which would require a fair amount of prep work, a small block Chev, or electric, this seems like the least expensive option.

Looking forward to seeing the completed installation and hearing driving impressions. I'm a big fan of the 2.1 as is. Pictures or it didn't happen.

Yes, strain, no stain.
I disagree with your statement. The speed limit here is 75mph on the freeway, which, to me means your pretty much floored most of the time on the flats, and all the time on the hills, and still not maintain the speed limit. A higher speed isn’t going to put that much extra strain on the trans. Also, being able to cruise at the speed limit would be nice, a trade off I’d be fine with.

[?Waldo?]

Floored or not floored, the amount of power the engine is producing is equal to the amount of strain on the engine components. The pedal position is irrelevant. You can disagree with that if you want but that doesn't make you right.

I'm not saying that the 2.1 engine cannot handle the added strain of producing more power. I'm also not saying that adding a turbo is a bad choice. Saying that the engine will be less strained is wrong, though, and is a disservice to anyone who might believe you.

I have been driving my wbx turbo for a couple of years now.
It’s a 1.9 stock high mileage original engine with 0.7 bar boost.
Makes my heavy high roof Westy follow traffic on the highway and steep hills easy without flooring it.
I have a 2.2 in the works mostly stock, only some small hipo parts... and a little bigger turbo..

The wbx is a very solid base even for high hp turbo engines!

So 180-220 hp on stock parts would be safe in my book.
Forged pistons and better rods (bolts) on the list above that.

Nice! That about 10psi. Got any pictures to show us? Is that just added on to the stock digijet FI or have moved on to aftermarket EFI?

That looks great! What model of turbo is that?
