what kind of engine does a 88tbird LX 5.0 have?
standard output 5.0 roller v8. its a different firing order than the mustang high output 5.0, and has flat top pistons, a smaller intake, and different heads.
dont 5.0 have 200hp for tbirds?
150 at the engine for a 88 5.0 tbird?
Yes.
well, doesnt doesnt make any sence because i beat my friends 98 grand am gt the has 200hp, and i have beaten a acura GS-R from a roll, i have beaten civics with a few bolt-ons. i couldnt do any of that with 150hp.
haha no what?
The car has 150 horsepower.
that makes me very sad. how much would i gain if i have a fully ported stock mustang intake manifold, a comp. polymers upper intake, a 75mm tb, and short headers with true dual exhaust?
Supposedly 155 for an '88 5.0 SO, because of the fake duals. Not like that extra 5 horsepower means anything.
Quicksilver, I can see you're already getting off to a bad start here, because you're triggering the "look, it's a n00b" response from some of the regulars. My advice to you is to take your time and not post so many new threads the moment you show up, no matter how enthusiastic you might be about your T-bird. Go to http://www.coolcats.net and read up on a lot of the info there.. most of it (all the important stuff, anyway) carries over between Cougars and T-birds, and is a good start for many of your questions. For the rest, do some lurking here and read subjects already posted on the things you're interested in.
The more you push here, the worse the responses are going to get from the people here who are getting tired of the excited-young-newbie routine. It's not entirely their fault, and it's not entirely your fault that others have shown up and wore our patience thin.. (do a search for the user named "i'm gay as hell" for a reference.. although I think that was someone's joke account) but you'll get a lot further here if you cool down a bit and do some reading before continuing. Just some friendly advice, not trying to pick on ya or anything. Not yet, anyway. :p
that makes me sad.. well, i have these mods, (just got them) fully ported stock lower intake manifold, comp polymers upper intake, 75mm throttle body, shorty headers with true dual exhaust.
To get anymore serious power you'll probably want to change the heads & cam. With that you'll probably be up to 5.0 HO spec, which is 225 horses.
ok, thanks alot for your help, i apprecaite it.

All the reading you need regarding the HO conversion.
I'd say skip the big throttle body unless you plan some serious mods.. over at Lincolns Online there was a discussion about this, and they think that some throttle response is lost with it.
EDIT: Here's a guy running a Kenne Bell supercharger on an HO and even he doesn't feel the need for a bigger TB:

Can't say everyone here will agree since I don't know their opinions on it.. but Bluegrass over there is generally considered a pretty knowledgeable guy from what I gather.
you will kill it....bigger isnt always better, IMHO it will be slower then stock.
the box style intakes work well with hi rpm combo's or forced induction. neither of wich you have.
a gear 3.55-3.73
headers and a good 2.5" exhaust will help some
mustang upper intake and throttle body and spacer will help
a head something 'around' a 165cc intake port (edelbrock performer/tfs twisted wedge/afr165's) and cam (tfs stage 1 or ford motorsport b303) upgrade along with an h.o computer and maf swap will help
But then again all i can offer is advice take it for what you want.
Grand Am w/200hp? Did he have it dyno tested? I had a Grand Am GT and it only had 155hp. I has hard pressed to find enough mods to generate 20hp much less 45hp. But it's been awhile since I've owned that car or even thought about a GM engine.
Oh BTW, welcome to the boards. :)
am I the only one to notice its "tappet" not tapped?
That 280ft lbs of torque might be the reason you won.
Oh yeah you also have the shiznitty 14lb/hour injectors.
And the even shiznittier 65 LPH fuel pump......
wow, you guys sure do know alot about thunderbirds.. thanks for helping me out!
what is a good fuel pump and injectors to get?
Most common fuel pump is the 255lph pump. You can get them from just about any performance shop or catalog (http://"http://www.jegs.com/webapp/wcs/stores/servlet/CategoryDisplay?lang=-1&catalogId=10002&storeId=10001&categoryId=23125").
If you have the stock computer I wouldn't put anything bigger than 19lb. injectors in it.
All right here you go... The main thing to remember is there MUST be a proper air to fuel ratio(A/F) to make effecient power... Basically whats this means, if you do a mod to increase air into the engine there must be a accompaning increase in fuel or it will be too lean(or if you add just fuel, as in larger injectors it will be too rich) The stock Bird/Cougar 5.0 is a ballanced package to produce the rated 150/155hp. IF you change ANY part of the system LIKELY you will upset this ballance and possibly the car will be slower as well as have drivability problems. Remember to keep A/F in the back of your mind and you'll be ahead of the game(do a little searching on the net).
So whatsa guy(or gal) to do??? In almost every case, it's the exaust system that needs attention FIRST(remember if it can't $hit, it won't be able to eat). What you do here will affect future HP plans so if you don't want change exaust systems twice, get a FULL 2 1/2" dual system, with 1 1/2" headers for stock heads or 1 5/8" for aftermarket heads. You could use stock Stang headers now(cheap) then get larger ones if you get some good heads. With the exaust system intake mods are in order. On a stock SO the 60mm Stang Tbody/EGR spacer is plenty. Also you could change to the HO upper, but for the difference I would not spend any money on one. Plan on a Cobra or other aftermarket intake and be done with it. Now you've got more air, you can add a LITTLE more fuel. Best way at this point would be to get an adjustable fuel pressure regulator(and gage) then increase the pressure till the car runs it's best. Stock is 39psi something on the order of 42-44psi would be in the ball park.
This is just a start, as there are so many possibilities it can make you head spin(you may want to skip minor mods and go full HO with cam and head change, just remember the exaust system is still the first mod).... BTW welcome to the board...
