I've just joined the site as I have an interest in this thread... I've recently been buying a 2001 S3 with 68k miles and what I gather is a common(ish) K04 problem in that it has a cracked exhaust housing. I was aware of this and have bought the car needing repair and had spoken to CR Turbos before stumbling upon this site. My question is, what do people think of the CR hybrid K04's? Having read the thread I am guessing they are rated quite highly but my dliemna is, my S3 has been to Jabbasport already for a custom remap, has a Jabbasport boost controller fitted, FMIC, Milltek cat back, induction kit etc. and ran a respectable 290bhp and 320lb/ft on their rollers with printouts to prove.
Is it worth upgrading to a CR hybrid considering the numbers it has already done and bearing in mind the additional cost? I am going to need another remap and more than likely a set of 440's to go with the turbo so is this extra cost worth the power I will gain? I am assuming I will be doing well to get over 320 and to be honest, I don't really want to go more than 330/340 as I don't want to be replacing pistons & rods in what is intended to be my daily driver.... Also, the torque figures I have read in this thread seem rather low to me bearing in mind the BHP and that confuses me, I'm failing to see how that can be the case....?
I would be keen to hear peoples thoughts on this as I need to make a decision sooner rather than later re: standard replacement K04 or hybrid..... decisions, decisions.... the car is already stripped so I just need to order the bits either way.
As you guys have obviously been kicking about in S3's for a lot longer than me I would appreciate your thoughts one way or the other!!!
Cheers
