Don't know if this is the best place for this. Please move if it isn't.
I have an auto 92 245. Long term plan is to do a 16V B230 build and swap it in with a T5 manual at the same time. I'll be doing this in my free time with no real deadlines. Updates probably won't be that frequent.
I've got decent experience working on cars but have never had a reason to do an engine build or rebuild. This is my excuse to learn some things. I wanted to do a build thread to take all the advise I can get and hopefully leave behind some useful information.
Goals:
Reliable NA 200hp would be great. But main thing is to have usable powerband. I would rather keep decent low/mid torque if it meant losing it to get an extra 10hp at top end.
Initial Plan:
-B234f head.
-93 squirter B230 block
-I want to be able to run 87 octane so CR will probably have to be below 9.3:1
-MS3X using DSM CAS
-b234f intake modified with tapered log like most people here do to clear the brake booster
-I'll probably weld up my own 4-2-1 header setup. Try to do some math to get primary lengths and merge placement close. I'm tempted to run per cylinder O2 sensors on the primaries to give individual cylinder trim. The custom intake will make even cylinder distribution unlikely, so just work around it with tuning
-no real direction yet on crank, rods, pistons. I would love to do a Penta crank and go 2.5l but I don't think I can afford it
I've got a junkyard B234f already. I'll have a 93 B230 squirter block soon.
Tonight's minor triumph was not breaking any exhaust studs getting the manifold off. 7 out 9 were fused with rust and pulled the stud with the nut
Any input/advise welcome.
