so, ima chime in here. the jz series engines are great, but to put one in your mk3 (or any chassis that didnt have one stock) is going to be spendy and cause more down time, especially if you arent doing the conversion yourself.

the m series motors are great reliable engines, and most of the generic problems can be fixed simply.

1-BHG. if you buy a used engine and dont need to rebuild (always recommended), retorque the head bolts to 72 lb ft (dont loosen first!).

2- oil pressure. stock is sposed to me 4.3 psi at idle (scary!). easiest thing to do is throw about 5mm of washers in the pressure relief spring, ups ur psi decently (my freinds john sees about 12 psi on his buggy with this mod).

3- rod bolts. the stock rod bolts are good but if you drive hard, they will fail. upgrading to the ARP rod bolts is cheap, easy and totally effective. ur rods will have to be resized after u install the bolts (my machine shop charges 7 bux a rod, whoopie).

really thats it, they are simple, reliable and incredibly durable. toyota blocks and cranks are incredibly stout, id say stock block, rods and crank can prolly surpass 700 hp.
