i saw these stainless steel headers on ebay to buy, it's for 3S-GE but for a 94 celica would it still fit in my 88 Celica?
Details are lacking. There's a few different motors in the '94. Most of the header choice from the 6th gen will not fit, unless it's a JDM 3sge then it 'may' fit your '88. But what kinda '88 is it? Also, your car only has one 'header'. 'headers' (plural) is for when there are more than 1 exhaust manifold (ie v6, v8, w12, etc.
watch out, if there the OBX headers they will NOT fit the 162 (3s-ge) due to starter location. though they say it will. on some sites they have finally noted that they will only fit the fe motor.
its all conflicting, none of it makes sense. the 3sfe, 3sge and 5sfe all have the same bolt up pattern on the head
1.8 ST is the 7A-FE equipped one, AT200. It's very common in europe. This one will only fit the 7A-FE, they clearly don't know that the 3SGE is a total different engine.
do you have the ge motor or the fe? heres a link to the fe header. http://www.amazon.com/OBX-Header-86..._4?ie=UTF8&s=automotive&qid=1301929713&sr=8-4
