im really liking the thought of a 3.0 sho swap for my s13. the enticement of a cheap 9k reliable 200+whp na swap is very interesting. that and itll fit under my hood.
SHO engines aren't CHEAP, but let me give you some pointers
first off find a 3.2L SHO engine out of an automatic SHO, much more torque
goto
http://www.shobrosgarage.com and get the most radical cams available... if u want some power this is the way to go!!! stage 2 or +40 cams...
asjust the valve lash(unless ur putting in new cams which will have to be done anyway)replace this:
water pumpcrank sensorcam sensorfront sealrear sealoil pan sealrod bearings.... a ****en mustvalve cover gasketsspark plug seals(usually comes with valve covers)new wiresnew plugsunder drive pulley set... a must for anything over 7200rpm IMHO
gasket match yout intake to heads, get the bigger bore secondar butterflies, get a bigger MAF.......
this will give u a worry free setup for the next 60k-100k miles that can make about 260whp....
I was going to do this but I couldn't see how it will fit, the intake manifold is MASSIVE..... albeit one of the best features of the engine sans the crank/heads
a custom intake manifold will make things 10x easier, besides that get ready to cut metal on your s13....
let me know if u ever need help with a SHO engine, I know a lot of sites with write-ups on how to do maintenance to it....... if nothing else atleast change the rod bearings while its out of the car.... I had 2 of em
great engine love the power..... makes my 240sx seem like a 10 speed bicycle as far as power is concerned
P.S.
he's right, SHO engines are in excess of 10 grand from the dealer... not a junkyard tho..... sucks if u get one with a spun rod bearing tho, then u need another crank
while I'm at it make sure the crank key isn't beating itself an oblonged hole in the crank..... those are the two ways to F up a SHO engine.....
make sure crank pulley is torqued to spec and rod bearings are changed
