need better engine

what is the most powerful engine i can put in my 94 protege?

also my car is currenlty killing good exspensive batteries in a week and i took it to the auto shop they said the charging system and altenator are fine and suggestions on what it could be would really help

cant help you on your engine question.... it was too vague.... whats your budget? power goals? etc..

As far as your battery problem... sounds like you have an electrical draw somewhere... do you have an aftermarket stereo??

well my budget is around a couple of thousand so what is the best engine ican get for that in the end i want a turbo and what not upgrades for power but i cant find anything for the 1.8 litre sohc i was jus gonna upgrade my chip and fuel injection and upsize my pistons and what not but i wanna look into options for other engines first and yes i have an aftermarket stereo but it still kills batteries even when i unhook it

for a couple grand... you wont find a motor... look into doing things to your excisting motor...

As far as the Battery... Im assuming you have an aftermarket head unit as well? un plug that... it could be drawing too much power even with the car shut off

no i dont have an after market head jus bought the car haven't touched the engine yet as i was gonna see about gettin the bigger engine but a friend of mine said it might be a short in the starter is that possible?and would a 95 amp altnator and a 95 amp isolator be enough to charge two batteries?

Im assuming the second battery is for the stereo? i would say the problem lies somewhere in the wiring for that

well another problem is that even when i put a new battery in my lights are still dim like my dash lights besides my signal arrow it still flashes bright

ok, have you upgraded the alt to a higher output one??

no not yet but another thing is even when i unhook the battery after its started it stays running

and whether or not the battery is hooked up when its running the lights are dim

which battery? how are both batteries wired? your forgetting i cant see how you have everything wired... so when you say "battery" i have no clue which one youre talking about.... and i dont know how its wired so i cant say anything about it running or not

sry i only have the regular one hooked up right now aint quite sure how to hook up the other battery myself

ok, well let me give you some advice... dont bother hooking up a second batery... cuz unless your making an all out competition ready stereo.. you wont need one... upgrade the Alt, get a Cap, and you should be good to go...
