I installed stock pistons (forged <-factory) I wasn't planning on boosting over 20 psi. Although some have been successful boosting to around 25+ psi on a stock block. https://images.squarespace-cdn.com/content/v1/569af82fd82d5e0d876b0b84/1454383805731-WTJJX5NYGY9N9C57BYCT/20121102_150828.jpg Car Stuff - Bottom View I pulled this block out from a junk yard...I drove my dads toyota corolla and diassembled an entire long block and put it in the trunk. https://images.squarespace-cdn.com/content/v1/569af82fd82d5e0d876b0b84/1454383809961-4E24X1DI3AATX3S1XW19/20121102_230358.jpg Car Stuff - Long Block Long block assembled on the engine stand. https://images.squarespace-cdn.com/content/v1/569af82fd82d5e0d876b0b84/1454383812272-YB629FOBF5AL9LBCBBLZ/20121102_230408.jpg Car Stuff - One more look at the top https://images.squarespace-cdn.com/content/v1/569af82fd82d5e0d876b0b84/1454383817689-DG8CGZNGD8H9F3XYFZJW/20121104_182554.jpg Car Stuff - Modified timing covers I installed a 6 bolt 4g63 block from a 1st generation eclipse (they generally had better stability, and the 7 bolts had a phenomenon of the crankshaft walking b/c of loose tolerances). https://images.squarespace-cdn.com/content/v1/569af82fd82d5e0d876b0b84/1454383822742-HUMSEWW2TNY3IINYZCYM/20121104_195527.jpg Car Stuff - Moment of Truth https://images.squarespace-cdn.com/content/v1/569af82fd82d5e0d876b0b84/1454383829650-321U5EDN4PX4568PQ7SG/20121104_220954.jpg Car Stuff - Magic Transmission bolted onto the block. This is much better to do outside of the engine. Otherwise I would have to bench press the transmission underneath the car up to the block (they do have transmission jacks, but I was/still am a poor student). https://images.squarespace-cdn.com/content/v1/569af82fd82d5e0d876b0b84/1454385938389-0AY0JRXO9AQPDQTCS2M8/20121103_170032.jpg Car Stuff - Timing Belt and Water Pump Install Engine has to be timed with a belt. Pistons and valves need to open synchronously in order to combust and generate work. Relatively low tech still. https://images.squarespace-cdn.com/content/v1/569af82fd82d5e0d876b0b84/1454383826054-CRK99X620XH4LP4Y10YX/20121104_215954.jpg Car Stuff - Putting the transmission onto the flywheel/clutch PAIN IN THE BUTT. You have to lift a 100+ lbs transmission and line it up with a small spline shaft into the clutch...fun times. https://images.squarespace-cdn.com/content/v1/569af82fd82d5e0d876b0b84/1454383816613-1JKFY0NDD2H6ELRWLBQM/20121104_182545.jpg Car Stuff - Cherry Picker I rented an engine hoist from aero rental (local business). The exhaust manifold and all peripherals were installed including the turbo. I was using a 14b (TD05H) turbo from a 1st gen eclipse I rebuilt. https://images.squarespace-cdn.com/content/v1/569af82fd82d5e0d876b0b84/1454383832336-AXYIBJY7HYHCY5IYY6S0/20121104_221243.jpg Car Stuff - Moment of Truth https://images.squarespace-cdn.com/content/v1/569af82fd82d5e0d876b0b84/1454383838532-UUQUR8FALYB10KD2ET84/20121104_234239.jpg Car Stuff - Placing the engine into the engine bay This step has to be the most satisfying. All of the engine mounts line up, and the engine is placed into its' final resting spot. https://images.squarespace-cdn.com/content/v1/569af82fd82d5e0d876b0b84/1454383839606-U7HAOXOA2NJ372N7Z19W/20121107_161756.jpg Car Stuff - Install everything else! I have done this way too many times (my previous generation cars had the same engine). From start to finish, I could remove the engine in about 2.5 hours (if nothing goes wrong). https://images.squarespace-cdn.com/content/v1/569af82fd82d5e0d876b0b84/1455385944655-AEGTTCRTL3073FEZ9UX8/image-asset.jpeg Car Stuff https://images.squarespace-cdn.com/content/v1/569af82fd82d5e0d876b0b84/1633960116161-AD6ON568TXOOY77Z19LM/totalled.png Car Stuff - Make it stand out *Not crosstrek https://images.squarespace-cdn.com/content/v1/569af82fd82d5e0d876b0b84/9167fa9c-a80b-4467-9308-b356f1b98d0d/IMG_20171106_171055.jpg Car Stuff - Make it stand out License plate scrubbed in case I ever cut you off in Pittsburgh, though this model/color are like locust in western PA. https://www.chunglab.ai/curriculum-vitae daily 0.75 2026-08-07 https://www.chunglab.ai/music daily 0.75 2026-08-18 https://images.squarespace-cdn.com/content/v1/569af82fd82d5e0d876b0b84/1455406253634-JYZ7AA0T2UNJBB0IBE6B/slider_steinway_02.jpg Music https://www.chunglab.ai/press-release daily 0.75 2026-08-07 https://images.squarespace-cdn.com/content/v1/569af82fd82d5e0d876b0b84/a00b224e-cdf1-4a93-aabe-cfdd5d972de9/Screenshot+2024-02-04+at+9.29.33%E2%80%AFPM.png https://images.squarespace-cdn.com/content/v1/569af82fd82d5e0d876b0b84/37bf099f-8786-4eb4-b7ce-4f5beb436242/pinch-logo.png https://images.squarespace-cdn.com/content/v1/569af82fd82d5e0d876b0b84/a1fb54e7-d301-4005-97a2-81f53d827f1c/NSF_logo.jpg https://images.squarespace-cdn.com/content/v1/569af82fd82d5e0d876b0b84/30c647f9-878d-4068-8222-284e4d61e872/Untitled.png https://images.squarespace-cdn.com/content/v1/569af82fd82d5e0d876b0b84/f4564387-cb34-4d36-bbb3-45b203931500/0321_F3_A1Fig4.png https://images.squarespace-cdn.com/content/v1/569af82fd82d5e0d876b0b84/1633959036375-II9LMM5IJDLLC4G5N1SE/Untitled.png https://images.squarespace-cdn.com/content/v1/569af82fd82d5e0d876b0b84/1632095336139-I291KSPH9P88H7NNHPWF/Untitled.png https://images.squarespace-cdn.com/content/v1/569af82fd82d5e0d876b0b84/1633951038145-NW9ALV2XPBOAA5ONAWDC/Untitled.png https://www.chunglab.ai/people daily 0.75 2026-08-18 https://images.squarespace-cdn.com/content/v1/569af82fd82d5e0d876b0b84/ed3cf496-f0c3-4aaa-a3a3-35d731dd5ed6/Untitled-1.png https://www.chunglab.ai/home daily 1.0 2026-08-13 https://images.squarespace-cdn.com/content/v1/569af82fd82d5e0d876b0b84/fa20ed3a-291f-4b08-b462-7c98bdd37f71/Picture3png.png https://images.squarespace-cdn.com/content/v1/569af82fd82d5e0d876b0b84/721e2aa3-14b0-43a4-8510-31849b059b98/IMG_0024.gif https://images.squarespace-cdn.com/content/v1/569af82fd82d5e0d876b0b84/1774900159976-WWQVC7YGK6UWNKQ52YWK/unsplash-image-YOy-ek-aBR0.jpg https://images.squarespace-cdn.com/content/v1/569af82fd82d5e0d876b0b84/dffc9faa-81f8-4d2e-9339-66414b6adf62/IMG_9765.png https://images.squarespace-cdn.com/content/v1/569af82fd82d5e0d876b0b84/de4aa45e-e14a-4fda-870d-1ea2f20bfcec/KakaoTalk_20260329_194400399.png https://images.squarespace-cdn.com/content/v1/569af82fd82d5e0d876b0b84/e9cfa36a-3caa-4910-a0c4-cfaa5f4f6ef6/Picture1.png https://www.chunglab.ai/publications daily 0.75 2026-08-11 https://www.chunglab.ai/lab-presentations daily 0.75 2026-08-18 https://www.chunglab.ai/research daily 0.75 2026-08-13 https://www.chunglab.ai/research/biomechanics monthly 0.5 2026-08-04 https://www.chunglab.ai/research/engineering monthly 0.5 2026-08-04 https://www.chunglab.ai/research/ai-overview monthly 0.5 2026-08-10
