[Mk2] [Turbo] Alloy crank pulley !!!!

[tarmac terrorist]

Right I have fitted a billet alloy crank pulley to my 2 it's been on there for a while now, but after hearing horror story's of cranks cracking & possibly the alloy one is the cause I am going to go back to standard, the problem is the part number for the mr2 engine is different to the celica st185 celica which is the base engine I'm using ,my question is what would you go for!!!
The only difference I can think is the 185 takes vibration from the transfer box as well & also runs the power steering as well, what would you choose,sw20 or st185 crank pulley ( they are different prices also but not worried about that)

I heard too many horror stories about alloy crank pulleys and didn't want to take the risk. For the gain you'll get over a stock harmonic balancer is it worth the risk?

I had my whole crank assembly balanced, obviously including the crank pulley and harmonic balancer, for me that was the best option not wanting to risk a failing alloy crank pulley or any damage as a result of one.

This is the same route i am going to take, the pics of split cranks was enough to make me steer clear. Although im told if you did install an alloy crank pulley and then had the crank balanced with this it should help. (still a risk with no harmonic balancer)

Still going for an oem one though as dont fancy another rebuild.

The ST185 pulley has one smaller pulley for the alternator belt. It isn't a direct fit if the alternator is located in the stock mr2 location. You could use an ST185 and get a different alternator belt, but personally I'd say go sw20
