Yes
yes, great upgreade!
Yes it can, the only difference is you need the oil gap plug that feeds the turbo off of the turbo head. other than that it will work perfectly fine with no issues. I would suggest taking the replacement head into a machine shop and having them look it over. I did the same thing with mine and was glad they did due to finding the valve stem oil boot seals were cracked and would leak oil not to mention they shaved the head down so I got a little more compression.
no, the transmission for the 4g63 is on the passenger side, the 420a is on the driver's side. you will have 5 speeds in reverse and 1 speed in forward if you try this even with a transmission adaptor.
The cylinder had bolt tightening sequence should begin by tightening the head bolts on each end of the head. Tighten the center head bolts. Work towards each end of the head, alternating back and forth.
Mitsubishi torque spec for the 2.0 and 2.6 head bolts are 65 to 72 foot pounds cold. Step one - all bolts to 15 lbs. Step two - all bolts to 30 lbs. Step three all bolts to final torque, used head bolts 65 lbs (not recommend re-using these kind of bolts), new bolts 70 to 72 is perfect! Bolt sequence, start with the center two bolts and work your way out. If you are not familiar with standard head bolt tightening sequences it would be a good idea to have a trained tech do the work.
NO they will not work. You MUST use a high rail head where the valve cover bolts are in the center of the head. 1988 to 1999 will work.
Work inward in a circular motion.
The transmission from a 4g63 will work on a4g63t whether it is standard or automatic however the standard transmission from the non-turbo engine will have a different final gear ratio than the turbo model. The automatic transmission from any model is essentially the same save the AWD model which has a secondary output shaft for the transfer case.
The cylinder head bolts onto the engine block, it is the part that allows air in and out of engine, and also the same part the spark plugs screw into. Head work can refer to several different components and is likely to cost a pretty penny.
Torquing head bolts without a torque angle meter is substantially harder than with one but it is very much possible. All it requires is keeping a steady hand and a keen eye on your work.
If your coolant is leaking, chances you have the head bolts pulling, a common problem on northstar engines. Dealer head bolt inserts don't work, they will tell you that, and no guarantee. The only 100% success rate fix would be " NS300L ". These are longer head bolts and inserts. You can find them on the web, and on Ebay.
