Ok I bought a few more parts for my swap this weekend from a guy who bought a wrecked supra from an auction... The supra was a 94TT and as built pretty well... It had a Greddy T78 single, a Greddy FMIC, all the electronics to go along with it and a G force ECU... Problem is since the car was bought from a auction the current owner has no idea what EXACTLY the car has... I got the fuel rail (stock) and the injectors.. I was thiking on the way home its hard for me t believe the car was running on completely stock fuel.... And since I have never owned TT injectors before maybe these aren't stock... Here is what I know about them... They have a kinda purple top, fit in the stock loction, and has this number on them... on one side it has a 329 and on the other it has a B 5630... These are prob. stock BUT I don't know Thanks everyone...If this doesn't help then maybe someone can tell me what to look for Thanks again

 

Are they top-feed or side-feed injectors? I'm thinking they are stock right now as well.

 

This will be a stupid question but how do I tell??? I found another number on the top (they are a little dirty) they say denso 23250-46060... any ideas

 

Pull one of the injectors out, you'll see mesh screen on the side of the injector I believe.

 

yep mesh so I think they are side feed.. Correct????

 

Yup sounds like you have the stock 550's

 

nah; i've seen side feed 680s before... just because their side feeds doesn't mean they are 550s

i'd go post at supraforums

 

Interesting..... I dont see many 680cc side feeds. All the supra owners I know usually change to top feeds during the fuel system upgrade. I guess there are those abnormal people out there though.

 

They could also be blitz 850cc side feed i will check my old fuel rail and post what color they are later.

 

Thanks everyone for the reply but I think I have stock 550s...I compared them to some in a friends 95 supra and they are the same... Who in the world runs a T78 and all the other upgrades and leaves the fuel stock..ol well...Thanks againTD

 

you'd be suprised...

saw one guy that used a T78 and stock fuel and an AEM... then ran additionals that sprayed methanol...
ran like 26-27psi on 93 octane with no knock
