hello so i blew a rod through the front and bottom of my block in my 2003 evo 8 i was surfing the net and found a evo 4 engine, trans, tcase, ecu, and maf. just womdering if anyone has put an evo 4 block in an 8 everyone i have tried to contact through the dealership thinks it will work i no the went to a bigger clutch diamater in prior years than mine but the trans is the same size n bolts up wondering if the head from 2003 will go on evo 4 block or if i just have to do the whole jdm swap

 

Just out of curiosity how did you blow a rod through your block?

 

was just getting onto the interstate coming down the on ramp and shifted from 4-5 at like 5300-5400 and it just went BOOM and ya here we sit with the motor on the floor again (3rd time this year) but now that it is on the floor i can insert my hand into the whole and spint the piece of the rod thats left on the crank so it was not the rod berring that siezed so i have no idea what went wrong in there still have yet to rip the head off of it n tear it all appart n what not just got motor out of the car at like 2:30-3:00 this morning

 

i would post pics but i have never figured out how to do it i put them on as attachments and they dont show up how do you get pics to show up on the thread

 

Evo 4 has crank walk isses and the evo 4 ECU as different from the 6-8 ECU

 

Just get a 4g64 block and build a 2.4l. 4g64 blocks are easily had and cheap(er)

 

isnt the crank walk issues only on start up? from what i have read on here and been told and its when you have the clutch pedal pressed on startup i bypassed my clutch saftey so i can start mine without the clutch in i am honestly just wondering if the block and heads are the same and i can rock this one for a while with my intake manni on it all other sensors are same and in the same spots only thing diff is intake i just planning to use this one while i am building another 2.3 being a pizza boy i just need my car back 4 work... n i no i deliver pizza in an evo but i live in montana and we get SNOW so ya AWD was a must and i love to roll in style everyday lol nothing better than an evo in my eyes n couldnt find a good block anywhere for what i am getting this other engine trans tcase ecu maf and wiring harness so ya just need to no if the block and head will wrk with my intake

 

They don't walk like the dsm 7 bolts so I would not worry that much about it as they are the better split thrust design like the 99 to 06 4g63.

 

nope ,one piece bearing and thrust on evo 4
