I'm no expert on turbo's but wouldn't a supra turbo be a little to big and spool up slowly??? Considering the turbo would originaly be from a 6 cyl. and you would be putting it on a 4 cyl. I'm not to sure either though.LOL You might not want to listen to me..... <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/wink.gif" border="0" valign="absmiddle" alt='

'> It may me that the stock Supra turbo is restrictive on that motor and would work well for your app. and just need a boost controler.Whatever...LOL.
