The Trial tuner Celica, when it was Blitz supercharged and Trial stroked (1.998cc) and making 283hp at the wheels, laped the Tsukuba circuit in 62 seconds, thats quicker than some Ferrari's. Check out how that compares to other stock and tuner cars: http://www.tuningpt.com/store/tsukuba.htm I think Trial runs their own supercharger setup now, and is making even more HP. Just goes to show a nicely setup FWD application with a good LSD and suspension can be very competitive. First of all u need to ask.. where are you gonna drive this car? Personally i know id only be driving on the street .. so id go mainly handling/aesthetic mods if ur after power id persoanlly go purist N/A route and get the 130-140kw at the wheels and beef up the handling and also ur driving skills and ud be a lot quicker than some random power car but cant handle .. u can enter an dexit corners fast and have alot more fun out of ur car. People like the kick of the turbo .. and so do i .. but i also love the rush from high revs screaming and knowing ur power band to its best. id also go 4-1 headers instead of 4-2-1 headers to make the most out of the top end .. i know some people are gonna criticise this as the stivo already has the hole in mid range and the 4-1 will emphasise it even more.
