Ultimate SR20 Rebuild Guide: Part 1 – The TeardownPosted on June 29, 2018July 25, 2018byNikita RushmanovAfter we’ve broken all the studs loose, we can fish out the nuts and washers with a magnet.Now because this engine has ARP head studs instead of head bolts, we also have to use a 3/16 hex wrench to break the studs loose.And then we can fish those out too.A couple of light taps with a rubber mallet is usually all that’s needed to get the head loose.We can now lift the head out. You have to hold the chain up so that the chain guide can move out of the way as you lift the head. It’s easier with two people, but totally doable alone.Now we can remove the head gasket. The particular gasket I have is an APEXI 0.9mm MLS gasket. It has been reused many times over the years so the factory coating has worn off in places, which is why I have it copper coated.RelatedPrevious page 1 2 3 4 5 6 7 8 9 10 11 12Next pageRelated TopicsEngineBottom EndRods and PistonsHead and HeadworkSR20SR20DET Previous Article SC300ProjectsLexusProject SC300 Road Racer: Part 17 – Get out there!

Just curious when youll be blueprinting the engine and doing assembly and posting that back on moto?Love it thanks man! RyanReplyNikita, Great write up! Can’t wait to see whats next with this. Will be doing a rebuild on my SR very soon.ReplyAwesome read great help.ReplyDon’t you risk damaging the crank pulley with that type of extractor?ReplyYes, I’ve broken my pulley using a 3 jaw puller like that before. It can be avoided if you’re careful and make sure to have the puller perfectly squared up with the crank and don’t apply any uneven pressure when turning the bolt.ReplyI’m surprised to hear that. I’ve never had issues, but I guess I’m careful. What type of puller do you recommend?ReplyIf I’m not wrong, the correct type is an harmonic balancer puller. That type pulls the pulley with two bolts that go in two threaded holes in the pulley.ReplyWell the problem is SR20 pulleys don’t have two threaded holes in them! That’s why I’ve been using a 3-jaw puller my entire life lol.A normal 3 jaw puller will work, just be careful with your placement of the arms and make sure not to let the puller bolt shift on the crank bolt. When I broke mine I was removing the pulley while the engine was in the car while trying not to hit the radiator so I had minimal space to work with and was using an open ended wrench so it was hard to not let the puller move around.I’m actually in the process of disassembling an engine and had no issues this time around removing the crank pulleyReplyHello i see that you live in LA and i wanted to know ware you take your block to the machine shop? it looks like i have a rod knock and am looking to rebuild my s14 Sr20det by myself . i would like to toake it to a machine shop that does things right. ware would you recommend me to take it ? i would really appreciate it.
