They all have either 6 or 7 bolts that attach the engine to the flywheel, or engine to the transmission, either or I forget sometimes. The 7-Bolt motors wich were used in some 93-94 and all of 95-98 Eclipse motors.
The 7-Bolt motors have a serious complication called "crankwalk". Now not all of them do, but a good number of the 7-bolt numbers will crankwalk. This is a condition where the crankshaft of the car is unbalanced and begins to rub against the CPS(crank position sensor) and destroys the crankshaft berrings. Not good; In the event this happens you WILL have to replace the motor, unless you catch it early.
If you're going to buy a 1G(1st Generation 90-94) eclipse, then u should be fine, because I have yet to see anymore than a handfull of those crankwalk.
If you're going to buy a 2G(2nd Generation 95-99) eclipse, then there is a good possiblity you could get crankwalk, especially in the 96-97 models.
Anywhos, I was just giving you some information on Eclipses wich does'nt pertain to you if you're buying a motor from a JDM company. All they sell are 6-Bolt motors(you could probably get 7-bolt on special request), The 4G63T Cyclone motors give about 190-210 HP at the crank. $1600 is'nt a bad price, but I'd have to recommend you go to www.totaljdm.com
to get the motor. They are the best JDM motor company arround. I believe their going rate is $1400(everything included). Also you're going to need a 2G bracket kit to put the 1G 6-Bolt motor in your car. The information on how to install a 2G-1G swap can be found at www.dsmtuners.com
. The job is a fairly easy bolt in, but my buddy, whom owns a Talon, says he can't pass emissions with the cylcone intake head(He lives in SoCal). So you may have to fork up another $20 bucks to get a USDM 1G intake header off a car in the junkyard.
Hope this helps good luck.
