RE: Which engine is best ?
Depends on what your after and how much you want to spend. For ultimate
performance and ease of install the 20v turbo is the best. Unfortunately the
cost of the motor and the cost of parts makes this about a $10000 project.
The performance is spectacular but the costs can be daunting. The install is
no harder than the 10v. As far as the 4kq transmission goes I have never seen
one fail because of too much hp. Alex is running pretty close to 400hp
through it and I don't think he has had to replace it. I think there is a
rally S2 running the 4kq gearbox if I am not mistaken.
The 10v turbo is a lot of fun and the conversion cost ~$3000 depending on what
you do. The parts are easy to find and the repairs are relatively simple.
See my previous posts regarding the conversion and the costs involved.
20v Na seems like a waste of time to me. It would require the same amount of
work as a 10v transplant and it would yield less hp. The motors aren't easy
to find and are not cheap to fix either.
864000csq turbo, 2 1/2 cat back, H&R-Boge, MC and loving it. Drilled and
stopping it. Koenig Cobra 16x7 with Yokohama A520's turning it, K&N and uh...
84 4000sq AKA: The beater.

I found a salvage yard that claims they can get Audi engines for "cheap".
Depending on availability, which engine
option is best for putting into my '86 4k ?
What are the drawbacks of each regarding maintainance, parts, reliability, fit
and finish into a 4k, any unforseen
experiences/BTDT's, and any other info felt necessary to add or include.
Can the stock 4kq transmission handle the power of these engines ?
