engine rebuild, trans am 1995

hello all,

i was wondering what it would cost to completely rebuild a 1995 Trans Am 5.7L engine, and how much it would cost if i did it myself, i have time and patience so that isnt a problem....

I think the engine needs to be rebuilt simply because i do not feel the same power i used to feel when it was younger

also, is there some way i can do a Ram Air conversion? is there abig enough advantage? is there something else you would reccommend to pass colder air?

and what is the top speed in km/h if you can?

ive already eliminated the second stage fan computer and now its activated by a switch, i love restoring my red birdie :D

okay thanks for reading

The cost of the rebuild depends on what type of power your expecting or the quality of parts you plan to put in. It can range from 1000-5000. Hard to say. Top speed it around 160-165MPH without any limiter. Don't know what that is in Km/h off the top of my head. Also yes you can turn it into a WS6 or Firehawk style with the use of a intake and ram air hood. Good Luck and keep us up to date

160 MPH times 1.6 equals 256 km/h

I recently sold my '95 Trans am that I did a lot of work to myself, so I can tell you a fair amount about them. FormulaLT1 is exactly right. You need to figure out what you wish to do with this car, and your budget. Do you want a stock rebuild? do you want a fair improvement in power? Where you live- what is legal (may or may not affect your decisions) Do you want a street car or an all out race car?

they make 383 stroker kits for these cars. I'd reccomend one of those if you can. I'd also highly reccomend a set of Airflow Research heads if you can afford it. They breathe so nice, and eliminate the high end "out of breath" feeling the stock LT1 suffers from. Of course, you cna have your stock heads ported for similiar results, but I was very happy with the AFR heads, so I'll reccomend them. Withte engine out- now's the time ot upgrade your exhaust system if you haven't already. get a good set of headers and have them ceramic coated!!! I didn't and it was no fun reconfiguring the speark plug wires to avoid instant burning away.

GM designed the 4th gen cars to go 160mph. My stock '95 T/A couldn't go this fast though. It stopped around 140. It wasn't a computer thing, it just didn't have enough power to overcome the aerodynamic drag. Yes, these super slick 4th gen cars are actually less aerodynamic than the 3rd gen T/A. Once I upped the power level- it could go that fast...

But, before you tear this car down, are you sure your current engine is shot? Have you performed a compression test? Have you given it a tune up? After years of use, the injectors could be partially clogged, the fuel filter could be partially clogged, the plugs and wires could be worn. There could be a host of other reasons too. All this will make your car run worse. I suggest to check these things first. Maybe put your car on a chassis dyno and see how it runs.

My car had 135k miles on it when I sold it but it'd run like a champ. Never replaced the cam, either....

As for the "ram air" conversion- you cna buy a hood. several companies make them, whether you want the 93-97 style or the 98-02 style. look online. the main disadvantage ofhte sttock non ram air set up is the restrictive factory air intake. there is a section by the corner of the radiator that is completely restrictive. Eliminate this with an aftermarket cold air intake or build your own and you'll be fine. I built mine with tubing from home depot and it worked great.

Let us know the condition of your engine- try tuning it up first and see how it goes. Good luck!!

how many miles are on the car! these things don't need to be rebuilt just because it lost a little power. it is more than likely something small and much cheaper and the money you save can go to buy the parts to make it a WS6 or Firehawk. those engines last around 200,000 miles as long as you take care of it, changing oil regularly and more often if you drag race or like to flog hard. but if you are going to spend the money for a rebuild the cost above is fairly accurate, you could go up into the tens of thousands and still be street legal. good luck

well i did 212 km/h, im guessing thats around 135mph

and before it used to be able to do more, and on the high revs the engine seems to lose power, and the acceleration isnt the same

so im thinking of making my own air intake ( some PVC piping and a sock filter lol)

but any other help would be useful

thanks again

yes i do change the oil alot, im 17 now, and i used to take it out and really open it up since i was 14.5 years old, and i can just feel the power loss

and its kinda sad, i love the 95 look more than the 98-2002 models

it is more than likely in the ignition system especially if it is acting up more at high revs. the coils could just be getting bad. not saying it is. there should be no real reason to rebuild unless you can stand to be without and let it sit for a bit while you build it a beast to put back in. the engine may at most just need a good set of rings. but if you do that you may as well bore it over and blueprint. have you ever seen how these engines come out of those cars?

yea its like givng birth to a whale, its dusgustingly large!! :D

i hate to think its anything to do with the engine but i pretty much changed everything on the car except for that

the plugs might need a change but im not going to hold them accountable
