Hi everyone,
I've been browsing here since I picked up my CQ back in late 2014. It was a total basket case with a number of issues and half-completed interior swap (tan to black) at the time. I did a bunch of work right out of the gate (all new control arms, bushings, calipers, rotors, pads, springs, shocks, tie rods/ends, tires, clutch slave, electrical work) and then let it sit for a long time as I worked on other projects.
The herd is starting to thin to free up time and resources, so I'm focusing on the plan for the motor build next as I wrap up the interior work and get the exterior ready for paint. I've already swapped the B4 hood and RS 2 headlights, as well as euro cabrio bumpers I sourced from the UK to get rid of the ugly US-spec bodywork.
The goal is a high-revving 500hp-ish turbo 7A with an 0A3 6spd out of a B7 RS 4 (I've already got that trans sitting here in my garage). Knowing me, it'll probably take until the end of 2021 or longer, but gotta start somewhere and sometime, right?
Currently, the plan is to keep the 7A block and crank, throw in a set of scat or pauter rods, JE pistons, coated main and rod bearings, 034 solid lifters and valve springs in the 7A head, an EFR or Xona turbo, FMIC, and standalone engine management to run E85. I don't really know how high the 7A cam wants to rev, but I'm hoping to get close to an 8K RPM redline, so I'd assume a custom grind might be in order. Manifolds and specific fueling components are TBD, but I'd like to keep AC and power steering in this thing.
I've owned 13 Audis over the years; and my first was a 1994 90 S (yeah, FWD, last time I made that mistake) back in 2004, and I had passed up a Coupe Quattro that needed minor work at the time and have regretted it ever since, hence why reviving this CQ is important to me.
My Audi fleet has included 3x B5 A4s, 3x B5 S4s, 2x B7 RS 4s, a B8.5 RS 5, a C5 RS 6, and currently a Gen1 R8 V10. The only street-going Audis I have now are this CQ and the R8. The rest of the garage is rounded out with a 914 for sunny days, 987 Cayman S for mountain runs, an E36 M3 and C6 Z06 for HPDE duty, and a B5 A4 1.8tqm and an E28 535i for Lemons/Chump Car racing.
Internal motor work doesn't scare me off as I've pulled apart my LS7 twice, rebuilt a few M30 bottom ends for the Lemons BMWs, and rebuilt the valvetrain on my S52 when the head gasket blew and cracked the head.
The goal with this car is something looking OEM+ while packing a nice punch. I just sold my 425whp B5 S4 Avant and need something to replace that turbo fun. I don't intend to drag race this car much, if ever, but I do love a high-revving motor and the trans is geared for an 8K+ RPM lump.
I'm sure I'll be peppering you all with questions about manifolds, valvetrains, and drivetrains (oh my), so thanks in advance for sharing your wealth of knowledge! I know very, very little about these platforms but am hoping to change that in the near future as this project finally comes to fruition.

Still a long way to go, clearly, but let's get to it!
