Unless there's a problem with your W58 I'd wait on the R154 swap and swap it in when you get the GTE. It's a much heavier transmission and generally not as smooth shifting. Spend the money on other components which you'll still be able to use with the GTE though... fuel mods, suspension, etc.

Krem, just because an engine is from Japan and has fewer miles doesn't mean it's not complete garbage. A lot of those engines were beat to hell and/or saw nothing but city miles... they're also still 20 years old. If you get a JDM you still should plan on having to rebuild it.

Oh, that's right! I forgot you're swapping from an auto.... in that case, swapping to a R154 won't add any more weight than you've already got in there, so go for it. Might as well only buy one transmission.

ok so the exhaust manifold is off. totally easier than i thought. ok off to krage for that hex head thing so i can take off the head

soooo just so you all know. its a 14mm hex

***EDIT*** 10mm for head bolts.

When you remove the head bolts you need to clean out any and all oil in the hole and any debris which may have collected there; Failure to do so may prevent the allen bit from entering the opening completely.

If you cannot get a bolt out all the way using constant steady pressure AND the socket is in all the way you can try: Pounding downward on the head of the bolt a few times with a rubber mallet; Use a breaker bar and while you hold it FIRMLY in place have someone tap the end of the handle several timed with a hammer; AND, spray the area thoroughly with a GOOD penetrating oil (WD-40 does not count as a good penetrant).

As for the bolts you've already stripped, go to the hardware store and try to find an allen bit or regular allen wrench that's just a *tiny* bit larger than yours, it'll most likely be an SAE size unless you've got a shop in the area which can order .5mm bits. Take it home and tap it in with a hammer... you know the drill from there. Some people have luck with easy outs; Grinding the head off the bolt usually results in some heavy gouges in the mating area directly under the bolt head and as such getting an accurate torque thereafter is unlikely without having the area machined.... not to mention all the debris you'll have to worry about flushing out of the block. Note: If all you can find that'll fit is a regular L shaped allen wrench you can just cut it off and slip it into a regular socket.

If I think of anything else I'll let you know.

EDIT: Oh, and don't be afraid to use a LOT of penetrant... it's cheap enough. Soak the bolts, wait an hour, soak again, wait another hour, soak again.... repeat a often as you wish, then let it sit for a few hours before going at it again. When you do go at it again make sure the allen is going in all the way before you try to remove the bolt.
