CB has a very good reputation in the VW engine community, not perfect but far better than most. I have had 2 of their engines and I had no CB caused engine problems at all. They may be more expensive than some, but there is a good reason why they are....has to do with the quality of parts used, the expertise of the builder (Pat Downs has an excellent rep in the business, he is the primary builder at CB), as well as the support they provide. I would take a CB engine at more $$$ over a Mofoco, or GEM, or any number of so called volume builders. Search thesamba.com for builders and threads regarding issues....and I have no interest in CB or any of the other builders either...

A little late to the post, but the CB 2110 engine I have in my I.M built by Pat Downs is one of the best Boxer engines I've ever owned, & that includes about 36 Porsche 356 engines from factory Supers, S90's, SC's, 912's & some Rally engines built by the best in the industry. This engine built by Pat is awesome, smooth, cool running & flawless after 37k miles.

A fellow forum member, Felix Bircher, once let me drive his CB Performance engine equipped IM Convertible D and it was smooth, powerful and so responsive you'd think you were driving a FI equipped car. The car barely vibrated at idle. You get what you pay for, definitely.

For members living in the Michigan area, I had Petrucci Racing Engines build me a 2332 back in 1992! That's when it was unheard of to run that big a motor on the street. I've had it in a couple of different cars over the years and it still runs strong today in my speedster and all I've ever done to that motor is valve adjustments and tune-ups. Primo is his first name, he's a machinist by trade, also has an in-house flow bench and dyno. Does all his own work, very meticulas!  Super nice guy, I beleive he's still in buiseness in Farmington Heights just out side of Detroit.

Jesse- Do you know the motor specs? Valve sizes and porting, cam, exhaust, compression ratio, carbs? How high does it rev with power before it peaks in 3rd or 4th gear?

now you are asking a skill testing question;it's been over twenty years ago since I had the motor built. I'll have to do some digging to find the paperwork for specs. . It's a low compression motor  2332,  7.5-1 ,  scat forged crank, 044 heads with 10 or 12 hours of pot/flowbench work,scat 1.5 ratio rockers 48IDF weber carbs. Primo wanted to run a dual ramp Crower cam @ the time but it wasn't available so he used an Engle with some serious specs. but don't remember the lift and duration on the cam or the valve sizes. I've had this motor up to 6500 rpm in third gear a number of times and 6000rpm in forth @ well over 100mph. 

I have mofoco heads & cb heads, Ive bought a lot form cb, a little from mofoco, there both great companys, cb is more power oriented than mofoco, mofoco heads are street heads.cb has heads for street&strip.if I wasasent building my own I would probably go with cb. but they both have good reps.cb builda a lot more performance motors than roy does.

genes school wasent always right, and lower cr? whats that? lower than 12:1?11:1?10:1? I would not go lower than 9:1 on any, but most importaint is to make sure you have proper quench. .040" quench +- .005 , my 2028 has 10.4 cr. ( so it is kinda low)cools just fine, runs great. but the entire package needs to work togeather.engine,acm,heads,cooling,oil,induction,exhaust,tins&sourounding aeras,shroud, distributor, state of tune,all of it, not just shiney ****.
