I have been browsing this forum for quite some time and have noticed that NO COMPANY make a header for the 2.2l 5sfe. SSAutochrome was about to but then people backed out (and yes, I have seen claims of their poor quality with some products. Fortunately this header wasn't bad. There was one or two instances where they did crack or break though in the MR2 community, and that's about it).
I had three MK II MR2s with the 5sfe. I also had the SSAC header on one of them. Let me tell you the performance improvement was noticable right away. It was almost like night and day. More pull and it ran quicker through the gears. When I had to put the stock exhaust manifold back on for inspection, the car ran much slower, easily noticable. Now, the NA MR2 weighs in at @ 2650 lbs. The 94-99 Celica GT hardtop weighs in at @ 2450 lbs, correct? A good header would probably make it quicker in a line than the MR2, which felt good in a line. Is there atleast a header in the works from a reputable aftermarket company? I'm probably going to be buying a 6th gen celica in the near future as my new daily driver. Is there any place where I can see the yearly updates they did to the celica to fix problems from the previous year? Like for example, in 93, the MR2 fixed some electrical problems or quirks, and upgraded the suspension and other things. Is there a list like this for the 6th gen celicas? |

The Celica GTs weigh around 2600 pounds depending on options and such. Only the Celica ST coupe weighs less than 2500 pounds. A bare bones hardtop MR2 (mine) weighs a little bit over 2600 pounds, T-tops and sunroof ones are even heavier. They're about the same. The reason the MR2 is heavy, front and rear firewalls, reinforced front and rear chassis... Oh... the Celica GT is not as quick as an n/a MR2...
As for modifications, IMO, the 7AFE in the Celica ST is a better platform for n/a modification. The problem with the 5SFE is the way it was deisgned to make torque. The piston dwell and such is very poor for making top-end power, so adding on a header isn't gonna make a big difference. The 7AFE on the other hand can hold its own modified. Oh... and there's no reason the MR2 5SFE header won't work on the Celica. I'd imagine only some minor modifications are needed for it to work. -------------------- "It's ok to be naked girl...
