a hmmm question

ok so here goes.. i have a 91 eclipse gs.. that i blew the engine up in.. i tore it out and sent it off to the machine shop.. in the proccess i found a

91 gst engine and after some pondering decided that i would really like to have a turbo.. then with some research i found that i would need a donor car to make mine turbo.. so with a lil more pondering.. and yet still more pondering i have not decided which way i want to go.. there is also 97 gst in my life.. in which the lifters are tapping like crazy and the oil pump is going bad.. i realize mine is a 1g and the other is a 2g, but from looking over both the engines outside we cant find any differences between the 2.. does anyone know what the differences are? or where i can find out.. my guess would be the balance or maybe the crank shaft.. any insight to my issues would be much appreciated.. thanks for all ur help =)

1G has a 6 bolt flywheel, 2G has 7 bolt flywheel, and smaller rods. The 2G turbo is also infamous for crankwalk that destroys the engine. Crank sensors are different, head bolts (I think) are different. Stick with the 1G engine, ditch the 2G.

well thats what i wanted to do in the first place.. but i wasnt sure what the differences were between the 2 engines.. i didnt know if it would work.. is there gonna be alot of things to convert when switching the engines.. my 91 gst engine has 85,000 miles on it.. and the 97 has

150,000.. and like i said the lifters in it are tapping really bad now.. worse than they were when i started this post.. lol.. can u point me in the direction of some place i can find more information on this?

it's probably not the lifters you hear but the crank rotor striking the crankshaft angle sensor. if this is the case, your motor is on it's last legs...... there are a few items needed from the 1G car and some very minor modifications. this swap has become very common in the last year or so. here's some more info:

marco's site (magnus) appears to be down right now but this is your destination......he has it all, even the parts required in kit form. you can also scrounge all of this at a junkyard, the trader (

) or on ebay. when you have it all apart, replace the lifters with the new units, most of the noise in your motor will vanish. go here and read:

there's a ton of engine swap info there.

the link i gave you before is to the yahoo group that is dedicated to the swap. lurk through the archives, this is required reading. keep this car for a hobby and keep another for back up to get you to work! have fun....

thanks for all your help.. i'll continue on with my research process with the links you gave me.. the 97 is my bf's car and he wants to take it off the road for winter anyway.. becuz they sit low to the ground as it is.. but its lowered another 2 inches and he really doesnt want to run it in the snow.. lol cant say i blame him.. so this will be a good project for the snowy monthes ahead.. and my brother just found me a 1998 gst with a blown engine.. i can see i am going to turn into an eclipse junkyard!!!

It seems really hard to find the gst/gsx's here.. ya its pretty bad.. when u get out of the car ur knees are just about up to your chest.. and the back struts are going out of it now.. so it is really a fun ride.. the struts will be in this weekend so i guess i know what we are doing.. LOL and when mine breaks it breaks good.. the computer (pause) engine.. LOL.. i drove mine all winter long as well.. i only had a few problems with it.. but i preferred it to the z-28 camaro i had.. are u registered on that yahoo site?

2" of drop is really too low for a 2G car. you have VERY little travel to start with, at 2" of drop, you'll be on the bumpstops quite often. look for a GSX, it really kills the front drive car (front wheel drive just sucks.) in the summer i have fat sticky yokohama's, in the winter i put snow tires on mine and drive it everyday. the only time the car gets garaged is when it broken.....

i paid more for my GSX than the bank said it was worth. still it was a great buy. the gst is and always will be a front drive. my hard headed sister came home with an automatic transmission, front drive talon tsi . she found out for herself that the front drive version of the car stinks and the auto is even worse. get on dsmtalk and try to find some folks in your area that could bring you two up to speed over beer and pizza.

"and the back struts are going out of it now.. so it is really a fun ride.."

well, yeah..... remember what i said before about that 2" drop? you have been bottoming out the shock. look at the top of the shock body and you'll see oil and oily dirt because your stuff is ruined. you'll do the same with the new shocks and there is no warranty that will cover shocks that have been bottomed out. i have personally done this several times. you're going to have to increase spring rate, travel or both. i wouldn't use a cut-down bump stop either.

"i drove mine all winter long as well.. i only had a few problems with it.. but i preferred it to the z-28 camaro i had.."

yeah, because it's rear wheel drive.....

"are u registered on that yahoo site?"

yes... dead97gsx
