I'm actually still in research stages of rebuilding my GSR motor. It's losing compression. I've done a lot of work (motor swaps, head swaps etc) I've helped replace bearings, but no measurements, or clearances were taken and that's about the extent of my bottom end experience.

I have only the most basic idea of how to do rings, and bearings, but this is something I want to learn on and be able to do in the future. Any advice or step-by-step guides or anything like that?

Thanks in advance.

 

 

HELMS...Best tool in my tool box! Well I actually have Honda and Acura repair manuals (real HONDA/ACURA books) but the HELMS or even CHILTON are just as good and way less expensive. It will outline the basics and even go as far as a describing how to measure clearances. But most importantly...NEVER SECOND GUESS YOURSELF...Any doubts need to be comfirmed or denied before you run the motor...Its a machine...Be smarter than IT! Dont be scared, just tripple check everything. GOOD LUCK!

 

thanks. I'll definitely be investing in one of these pretty soon.

What other tools should I buy? I don't have any micrometers or anything.

 

Damn man its dying? Hit me up, I have built a few motors.

 

i could start with the tools i can think of you would need: torque wrench, piston ring compressor, bolt streach gauge, micrometer set, piston ring filer, plasticgage, clay for the checking valve to piston, degree wheel

what have i forgot now?

It only had like 60psi on #1, and 240 on all the others. I want this to be a learning experience for me. I'm going to be building a spare D16A6 for my CRX also. I was actually thinking of building the D first, but I need to get the hatch back on the road.

I'll definitely hit you up though

 

find a friend that works parts. I bought all my parts from a friend whom works for Acura, my buddy got me on average 40% off on parts, plus he got all the tech notes for specs and assembly/disassembly. Even if you stop in the parts dept at an acura dealer you might get lucky to get those tech notes.

 

Why would you need a bolt stretch gauge, i dont remember a single bolt that went by stretch and not torque

 

have you thought that your low compression could be a result of blown headgasket? rather then rebuild the bottom end? maybe you only need a vavle lashing job done also. a proper leak down test is answer this questions.

torque can be measure as both bolt stretch and head torque. Bolt stretch is the best method, but most of the time you can't get to the other end of the bolt in order to measure it. The bolts holding the rods to the crankshaft is usually measured as bolt stretch since you can reach both ends of the bolt.

measure the bolt head torque with a torque wrench is just a simpler way to guesstimate the bolt stretch.

Well, My current plan is to rebuild the tranny, then I'll do a leakdown test. BUT the head was recently resurfaced, 3-angle valve-job, oem headgasket, and ARP studs.

ALSO, the compression came up after spinning it over for a few minutes...any ideas why?
