£600 for short block refurb - Reasonable?

[omi]

Hi folks,

I'm building an E30 318iS Turbo, running 8:1 compression. Found the pistons (JE, gapless rings, £450 delivered) so I'm looking for somewhere to rebuild the bottom end.

I've been quoted circa £600 by a local firm to strip the short block, 1mm overbore, balance the rotating mass, replace all bearings, clean through the channels and crankcase and reassemble using the new pistons.

Does this sound reasonable?

It's just a bottom end rebuild... I'm sure they've done that before.

Sorry Busa, didn't mean to sound arsey... It's a place that solely does engine workups, 2 man unit, been at it some time... They gave me alot of confidence on the phone just by understanding what I wanted and why, and knew little technical nuances about the crank that most enthusiasts wouldn't have a clue about. (I've been reading an awful lot so I knew!)

I honestly didn't know or think that there may be varying tolerances between NA and FI engines... Can you explain these further of point me to some reference information?

Boosted, you seem to have a good reputation for such things from what I've read on here in Lurk mode. Might be small-fry for you, but would you be interested in the work based on a similar cost?
