I find the Turbobricks forum extremely hard to use. I have sent at least 5-10 messages to moderator asking why can't I access for sale/wanted listings, why can't I post or reply and I never get a reply. I'm sure I'm doing something incorrectly, my computer skills are average at best for an old geezer, but jeez, the courtesy of a reply to my questions would be nice. I seem to log in OK, but can't get things to work.
Since I have so much trouble with that forum, I've given up on looking for info there. This is a common problem with many of the forums for cars, bikes, etc; they are not user friendly for those with limited computer skills. There always seem to be those who like to show off their superior skills by using ever more arcane, obscure and "insider" abbreviations and jargon and delight in sneeringly ridiculing those of us who struggle. It was my, (mistaken, it seems), understanding that these forums were to be welcoming, inclusive, friendly places where folks could ask questions, seek advice, share horror stories, give advice, share info, recommend parts suppliers, and so on, but often that is not how it works.
I've tried to find the "Volvo Performance Handbook" but it is out of print and can't locate one for sale. (Amazon, Ebay, etc) Anybody have a spare? Is that a good starting point for info on red block performance options? From my limited inquiries so far, 200-225hp seems to be about the limit using readily available parts for a B21FT-cam, header, increased boost, etc. This is why I was going the V8 route. With the Mustang 5.0, (or the Chev), you're starting with 225hp or more and upping that with the vast amount of parts and detailed info out there is a realistic thing to consider.
With the B21FT, hot rod parts and info on how to build it and what to use is a lot more difficult to come by. And as for swapping out the B21FT for another Volvo motor with different head, turbo, etc, well that's an engine swap, too, with it's own set of problems.
As I said, i live in the Detroit area. I've gone to hundreds of car shows, cruise nights, I've shown (and won!) stuff at the Detroit Autorama and dozens of other shows and I've NEVER laid eyes on a hot rodded Volvo engine. I've seen Volvos with V8s, V6s, GM Quad 4s, even a Viper motor. Particularly interesting was a PV with a supercharged Buick 3.8V6 converted to RWD with a 5 speed manual trans. But NEVER seen a modified Volvo motor. So, build one of those? Ok, but where to begin?
By the way, If I remember correctly from the last strut replacement on the Turbo car, the Turbo struts are shorter and the springs are shorter and stiffer than the DL items. Compare the "stance" of a DL vs a Turbo car.
Don't know about steering rack, etc.
