I just wanted a opinion on my 00 Si. I raced a friends 2005 Celica GTS and lost pretty bad. Gts had: intake, intake manifold, header, cat, stage 1 clutch, flywheel, and full exhaust maybe chipped but I don't know as the dude and I don't talk so much. Si: intake, intake manifold, header. We launch and I will always pull ahead and then at the end of 1st gear he pull up, pop second and he crawls away little by little, By the end of second he is proable 2-3 cartlength ahead pop into third and he keep on pulling by the end of 3 and into fourth he is probable like 5 car length ahead and we slow down. We did it 4x and it was pretty much the same result I got lauch he got top end. He told me my SI was slow but I was like WTF I only got intake, intake manifold, header. While we were in our second race his brother blew pass by us like we were standing still in his JDM B16 EG and we were in second gear and he was behind us. JDM B16 EG had: intake, intake manifold, header, cat, 3inch catback, stage 3 clutch, 8lb flywheel, car was totally strip except for his seat, carbon fiber hood, engine was pretty strip like any other swap. It made me think because he had a b16 but that s**t blew past us and I had a b16 of course it is usdm but still. I just was just wondering if my Si was slow because if it is then it might be because of compression or mounts or something. Just want an honest opinion not a " Your car is slow as s**t" comment. I was shock that I lost but he had more parts then me so I thougt that might be the reason. We gonna race again. This is a battle of pride since he said my si was slow knowing what I had already. I am going to get new header 2"inlet 2,5" outlet, 2.5" cat, 2.5" catback because the header I had before were 1.5" inlet but 2.5" outlet. What do you think the result will be? Think about getting stage 3 clutch and 8lb flywheel.
