Why Doesn't Any Company Make A Header For The 5SFE Options

[CyberCT]

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?

I think the point was totally missed in this thread. Let me try to answer your question about the header...

I understand that you already owned an MR2 N/A with exhaust, header, and an intake and liked the boost in power. Currently for the 6th generation Celica GT with the 5SFE, there is no header readily available for sale in the US. However Genie (AUS) an almost direct fit for the Celica, and Hotshot makes a header that fits the 5SFE but doesnt bolt right on to the 6th gen. platform.

You're choices for the 6th Generation GT are to either try to get a Genie header overseas from Australia, or locate either a 3SFE Pacesetter header and make it fit, or do the same with a 5th gen header from Hotshot or an MR2 header made to fit, or even a 3SGE header. Most of these choices will require some modifications to make it fit right but would yield the results you're looking for.
