how do i find out about my engine

yea i got some questions and kinda need to find this out soon like how do i find out if my engine is a tbi or mfpi or something like that i think its throttle body im not sure so how would i go about finding this out plz i really hope someone can help me out on this cause im looking into buying chips for it but only some work with like tbi and tpi and ik i dont have tuned port injection but im not sure about throttle body and theres some other option about mfpi i think so lemme know plz if anyone knows how i go about finding this out

T.P.I. motor will have a long narrow peice top center and fuel rails and injecter per each cyl. a throttle body motor will have what looks like a carb on top

is it possible to post a picture of the engine w/o the air cleaner

umm i will work on getting a pic up but im about 100% sure its a tbi now cause it does look just like a carb on top it does have somethjing different which looks like two lil caps or something i think, over the carb on top so im pretty sure its tbi now but i will work on getting a pic up

sounds like TBI

ya pretty much what i figured it was i even asked my dad and he said it was but i mean i wanted to make sure cause i mean im not gonna spend like 200 bucks on a chip to boost performance and then it doesnt even work so thanks alot for all the help got anyother ideas for cheap performance parts or anything thats gonna boost the performance thats cheap or at least worth the price for a '89 RS

u want affordable performace? i have some tips. u can order the jegs magazine for free, look in it for the GM replacement coi. it produced 50000 volts, the original one prodec somewhere around 35000. i put that on mine, and i got better gas mileage and even horsepower. try to get some high performace plugs for it too. but i wouldnt get the crossfire plugs for it, my 350 didnt like them very much. i used some AC delco's with very pointy electrodes. top it off with a k&n air filter, and doing an oil and oil filter change would be great for it. i used castrol syntec, and i prefer it, 4.99 a quart, but it made a dam good difference. hope i can be of help

yea that was alot of help once i get a lil extra money i plan on doing almost all of it once again thanks alot for all the tips.
