Ah never knew that. So when I look at the table it's just the same so only max 5 extra ponies will be added then haha

Are the specs of the headers right at least? I´m especially curious about the inlet/outlet. They give me this specs:

--Specification--

Make/Year: Toyota Celica 1994 1995 1996 1997 1998 1999

Model: ST Only

Engine: 7AFE/3SGE 1.8L L4/4 Cylinder

Spec: 4-2-1 2pcs

Inlet/Outsize Size: 1.75"/2.0"

O2 Sensor Hole: 1/One

Note: Not Fit GT 2.2L 5SFE Engine

Thanks!

the header fits the 7afe engine as well as 4age if I'm correct. it will not fit any 2.0 or 2.2 liter engines.

i do have specs for outlet on the b-pipe on my other comp which is currently not working. i'll get them to you asap. if i remember. pm me in a week or so or just bug me till i tell you

That would be really nice. I'll keep bothering you untill you have the specs haha

No. Probably more like 6 - 7 I'd say tops. You only get a couple HP from the intake and the header doesn't do much either.

I have full exhaust and ebay headers and this setup is better than stock .

first off what year is your car?

if its pre 96 then look under the distributor for a bolt thats holding it. loosten the bolt that you can turn the distributor by hand. stick a wire in the diagnostic box jumpering Te and E1. the timing light should show you at 10 degrees BTDC. now turn the distributor clockwise and you will see the timing advance. running a 7A-FE at about 14-15 degrees BTDC will bake a huge change, however you must run a higher octane rating fuel.

I have a Europe 7AFE, it's from 1998, but still OBDI so the jumpering method should be it.
But to change the timing i always thought you have to turn the distributor cap, but thats not it, you have to turn the distribituor itself?!
Which is the minimum octane i should use when i advance the timing to 14 degress BTDC? Will it damage my engine anyway?

Thanks.

yeah its not the cap, you turn the entire distributor. your ratings are different so im not sure what number to use. I suggest the highest for regular pump gas. thats our 91 or 92 depending on states

That's our 95RON. I always use that. There a little to non fuel stations in our country where we can get less then 95RON. There's also a possibility to get 98RON (93-94AKI) but thats a bit more difficult already.

So when i change the timing that shouldn't be a problem?

And one additional question. Our cars do have knock sensors? Then advancing the timing a bit shouldn't be a problem at all i'd say?

No one?

yes it have knock sensor. even the outlet diameter on the website is exactly 2.0 inches like i told you...

Thanks.

Topic can be closed as far as i'm concerned

I have to add that i'm a N00B...took a look underneath the hood today...what do i have??? Yes a 4-2-1 OEM Toyota header! So that would be maybe 1-2 hp gains from a bit better designed header!
