I5 conversion followup questions...
 

Ok, so i am on the path to finding a 90Q for a 20v Turbo conversion. Would it be more wise to get the newest 90 i can find or should i look for one of the older 20v NA variety? What years were significant body changes made in the 90 and what are the differences between the years? A lot of stupid questions, help me out...

The newest geneeration 90 began in '93, the B4...
 

80/90s before '93 were based on the B3 chassis. The Coupe and Cabriolet are a B3/B4 mix.

You want a 90Q20V for the swap, its documented in many places how to do it
 

You could find one for sale on the AudiFans.com Marketplace, I just saw a couple on there the other day.

Wisest thing to do is buy a urS and Mod the hell out of it.

^^ best advice!

Where would you look for such instructions? Search

Yes, that would be "easier", but i just like the idea of a small chasis with the I5...

or get a b5 s4
 

pretty much the same price now considering the cost of a nice urs4 + mods (rs2 stuff, suspension, brakes)
