I've searched, read and browsed and googled. I have come across no clear or concise answer.
I understand the consensus is to run a dog dish flywheel instead of the dual mass. I have several question I hope can be answered and that my questions and the answer help others searching.
The setup is a b230fk (from a late 940/m90 car) going in a 245 with an M47 transmission. I know, most will say m47 is junk but that is what the owner wants. Also this is his daily and he is barely a spirited driver.
The b230fk is running wasted spark and about 0.75 bar of boost, perhaps a set of chips to the 200hp spec will follow.
So, keeping that in mind. I have a dual mass flywheel that was on the motor as it's an m90 car. Can i piece the following together to make it work with the m47 (I want te keep the LH2.4):
Dual mass m90 flywheel
M90 pressure plate
m47 clutch plate
m47 throwout
?
Other option would be to purchase a single mass LH2.4 flywheel and run the full m47 setup.
That was question one.
Question two is as follows with regards specfiicaly to the clutch disc. Here in The Netherlands I can get various clutches from Sachs. They offer 4 different types of 228mm 22 spline clutch plates. All have different part numbers. All have the following cross reference
type 1: Low power motors from 2/7/9's (we can disregard these)
Type 2: The 740/760 turbo's (b23et, b230et, b230ft etc) Part number: 1878 005 610 Sachs
Type 3: The D24/D24Tic Part number: 1861 905 039 Sachs
Type 4: The 16v range (b204, b234 etc) Part number: 1878 005 616 Sachs
So question is: which one of the last three. They are all 228mm. They are all 22 spline. What are the differences going to be? Springs in the centre?
Only differences I can tell are part numbers, power outputs are the higher end of factory be it torque on the diesels or hp on the turbo's. The ONLY difference in the specs I can find is that the Diesel is "type" of clutch is listed as "WTB" while the other two are "TB". Google couldn't help me on that one either.
I look forward to your responses. Thanks in advance.
