93 xj 4.0 died at 150k time to stroke it
Posted: April 4th, 2023, 7:45 pm
So was planing to slowly build the 98 long block I have on the side of the shop but the jeep had other ideas.
Cracked a piston and cylinder head in cylinder 1
So going to rebuild it and use the head off the 98 and put it on the 93 block
Trying to do a budget build kinda hard with today's prices
So far still tearing down the 4.0
Build want to get a parts list together to be ready any tips or insight will be much appreciated.
So planing on stroking to a 4.6 want to be able to run 87-89 octane and play nice with the stock ecu. So believe I need to keep my compression to 8.8 to 1 or 9.3 to 1 or at least in that ball park.
So far my recipe is a 4.2 crank with stock rods and .30 over pistons , new lifters and cam ( still haven't decided on a cam yet )
New rockers and push rods.
Should I upgrade the timing set and oil pump ?
Also should I just have the shop look over my stock rods or should I pick some up
