You would have to remove the fan and fan clutch to run this type of radiator, I have something similar, a Mishimoto unit that I fitted to my car a few years ago.

 

True that. I have read that it's preferred to swap the manual to an electric fan. A mishimoto is outside of my budget. So question is are these eBay units known to fit ok in this car?

 

No idea, check the dimensions and accessory fitment locations compare against original and perhaps aftermarket you can't afford, then decide.

 

Are silicone hoses worth it? I am also wondering if everthing in this kit is usable? I would hate to buy this deal and can only use half of these.
