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?

Ah yes but this is missing the whole point. BOLT ONs. A header and intake made a significant difference on my MR2. The MR2 is more rare than the 6th gen celica, so that's not the reason.


NO internal engine work, NO turbo, NO completely changing around the engine bay and many of it's parts. Just a header and intake. Plain and simple. I think the confusion here is everyone thinks "street beast" when modding. I just want a boost in power.

Nevertheless, I guess I'll just wait for a nice MR2 or GSR to show up around my area and buy that instead.

So do you just want a header, or do you want a car that you think is gonna be faster than an MR2 with the same engine? If you just want a header... buy an MR2 one and have an exhaust shop modify it to fit. If you want to be able to hang with 5SFE MR2's... well... you're not gonna. The MR2 is a bit quicker. My MR2 can throw down high 15 second 1/4 mile runs (stock) while the best I've seen out of lightly modded Celica GT's is low 16's...

Also... I don't think any of the Celica folks, aside from relative newbies, think "street beast". You're thinking a header is gonna make a whole lot of difference... we're just telling you it's not, and explaining why it's not... and then letting you know what WILL make a difference.
