    BobLoblaw's Build Blog

    Hello good peoples at G2IC! I thought it was time to put together a little build thread for my project.

    I'm working with a '92 GS with about 200k miles. My motor was getting a little tired (~100 PSI in cylinder #2) and it was time for a refresh. I decided to stick with the B18A as I have a nice ported non-vtec head that wasn't ready to retire yet. So I'm building a new motor with higher compression that will run on E-85. This is my first motor build ever so wish me luck!

    Here's the rough specs on the new motor:
    • B18A1 - .25 over with fresh bore and hone
    • Stock Rods (reconditioned)
    • ARP rod bolts
    • Stock Crank - polished and balanced
    • P30 Pistons (JDM B16A)
    • ITR Oil Pump
    • Ported PR4 Cylinder Head - "Stage 2", valve job, 25k miles on it and just refreshed and inspected for reinstall
    • ARP Head Studs
    • Crower 62-403 Stage 2 Camshafts
    • JG Adjustable Cam Gears
    • Innovate LC1 Wideband O2 Sensor
    • Socketed ECU (will probably run Chrome, but need to talk to a tuner still)
    • Transmission - need to decide if my 90-91 or 92-93 tranny is going on. Have seen conflicting reports as to if these are geared the same or not. I have a lightly-used ACT stage 2 clutch for the 90-91 that may dictate the 90-91 tranny going in.


    Aside from that, most anything replaceable on the engine has been or will be replaced. Lots of new OEM gaskets, seals, o-rings, sensors, etc.

    I don't really have a budget; just wanted to build a NA engine - correctly. I've probably spent around $2000 already, with probably another $2000 to go. I'm just spreading it out, this has been in the works for a year already.

    Currently the motor is almost assembled and getting near to install time. I'm also pulling the ABS and maybe A/C as part of the process. Pics to come soon.

    Here's the block I started with (thanks to BLKACK1):




    Have you ever seen anything so dirty?!? It went straight to the shop for cleaning, inspection, boring and honing.





    All clean and ready for some fresh pistons.


    The machinist ended up having to take .006" off the deck. I guess this motor had some overheating issues. I'd already bought .25 over pistons in case there were any issues and had him bore for a ~.02mm piston-to-cylinder clearance.

      No pics are showing up btw...

      Look forward to see how things turn out though. If you ever need an extra set of hands in the process let me know. I would be more than willing to help out.

        thanks for the offer, i might have to take you up on that sometime. some pics are up now...had to figure out how to hotlink to picasa.


        So next up was to get my bearings sized.
        Oil up the bolts:


        Layout the bearings based on bearing codes:


        Drop in the crank:


        Torque it down after putting on caps with plastigauge:


        Then disassemble, measure plastigauge - and that's when we realized how many brand new bearings won't even be used because they're the wrong size...


        Thanks again to BLKACK1 for the help here. We probably torqued that crank on 4 times and went through 3-4 orders of bearings before we got the clearances i wanted. But then we were finally ready to install:


        We ended up with .0015" clearances on all mains using all pink and red bearings.

          SOME Over heating issues, thats the understatement of the year

          Ahh the trails and tribluation of this build, its been a great learning experience

          hey shane, shoot me a text. I got a new phone and your number for somereason didnt transfer over


          In for more pics

            yea definitely a learning experience, but your will be a little easier now..haha i couldn't have made it this far without your help.

            for anyone who hasn't checked out BLKACK's build thread, do it now! it's sick!

              We dropped the pistons in next. We got lucky here and only had to change out one bearing to get .0015" across the board. A little but looser than I wanted, but they were even and within spec so i called it good.





              Check out the dome on these things!!



              That was a good point to pull the ported head from my running car to get it to the shop for reuse on this new block. Haven't driven it since last year now and oh how i miss it!



              I thought the champagne of beers was a good toast to hitting this milestone..haha.

              My garage doesn't operate without some sort of cold beverages flowing...usually PBR though...because.......

                    Holler. Looking great man! I wish I could have been there for more of the motor work. You need to do work on the weekdays dangit!

                      Thanks mang. We've made quite a bit more progress. Getting ready to finish up the little details on the block....waiting for more parts. I'll update pics soon.

                      I'm going to try and take a week off soon and spend a few full weekdays in the garage to get this thing finished. I'll hit you up

                            Better then average build thread with great detail.

                            Update often...

                              Thanks for the kind words.

                              Here are some pics of the head i'll be running. It's got a street port with a valve job about 25k miles ago. I had the machinist clean it up, check that the valve seats seal, and put new valve seals in. I had this on my stock motor with some Crane stage 2 cams and loved the results. I have high hopes for this with the new high comp motor and Crowers.

                              Has anyone ever had valves bend at the top before?
                              When he was inspecting this he found 13 valves that were ever so slightly bowed around 1-2" from the top (opposite end of the valve face). He said they were fine in the facing machine, but he noticed a little resistance when installing them. After rolling on a flat table, it was apparent they had slight bow shapes to them....very slight - I couldn't get the camera to capture it. Any ideas why? He said he hadn't seen that before. Didn't think the shaved valve guides would cause that (as he'd seen many shaved guides w/out bowing the valves) but maybe detonation. I'm just curious how that happened.

                              Anyway here's the head:


                              New Crower dual springs and retainers...and a camera strap

                                And installing the head:


                                New ARP studs


                                All torqued down


                                Droppin in the crowers


                                The host for this new beast


                                Now this is starting to look like a motor!

                                      Well I've made a little more progress... ABS is removed and got the cams in and timed and valves lashed.

                                      Still waiting for some parts to get this all put in. Innovative motor mounts have been back ordered for two weeks now. But I also ordered a box of OEM goodies, Innovate wideband, A/F gauge, Precision 440 injectors, walbro fuel pump, etc. Gonna put some time in this week and try to get 'er ready to drop in. If the damn mounts show up i might actually get it in this week.

                                      Here's Glynn reinstalling the cleaned M/C after we scrubbed down the engine bay.


                                      ABS swap in progress:




                                      And non-ABS brake lines and prop valve in:


                                      Yes I probably should have pulled the brake booster to clean and repaint, but what can i say - I'm lazy sometimes...ha.



                                      Here's the timing belt on. A word of warning to anyone using a TypeR Oil Pump: you have to switch to an OBDII lower timing belt cover as well. I learned that the hard way. If I were to do it again, I'd rebuild an LS pump with the spring shimmed like the GSR/TypeR.

                                          hahaha. I figured that picture would have any ladies on the board swooning over you.

                                          Just found this pic of the casualties from the ABS removal. That stuff weighs quite a bit, so you get some decent weight reduction from pulling the ABS as well.
