Got the Walbro 450 all finished up in the neon 🀘🏻😎🀘🏻 with a little bit of modifications to the fuel canister of course 😝 #neon #dodge #srt #srt4 #srt4junkies #boost #turbo #agp #bwoodyperformance #prothanebushings #seiboncarbonfiber #bcracing #brideseats #sparcousa #mishimoto #pavelsracingengines #extremeturbosystems #aem #streetscene815 #crowercams #walbro #walbro450

Finally got the cams, springs, and retainers all finished up in the neon😎 and I couldn’t be happier with them πŸ‘ŒπŸ»πŸ˜Ž also with some help from @harleynalan #neon #dodge #srt #srt4 #srt4junkies #boost #turbo #agp #bwoodyperformance #prothanebushings #seiboncarbonfiber #bcracing #brideseats #sparcousa #mishimoto #pavelsracingengines #extremeturbosystems #aem #streetscene815 #crowercams

The obligatory Instagram post or it didn't happen in real life. Still catching up on posts from 2017. Scroll through the pics! This engine from a 2007 Aston Martin Vantage 4.3 was fitted with twin turbos and somewhere between stock motor and tuning, the engine suffered one melted piston and three pistons with cracked ring lands. CP Carrillo were commissioned for forged I-beam rods and low compression pistons with coatings. ACL Race Series rod and main bearings were used. ARP studs and bolts used where possible. Cylinders heads rebuilt to OEM spec. Devil is in the details. Everything had to be inspected and cleaned. Debris was everywhere. Dry sump oil tank was cut open, baffles removed, everything cleaned, and the tank welded bank together. Oil cooler was replaced. Oil thermostat disassembled and cleaned. All oil lines cleaned. Dry sump oil pan and oil pumps disassembled and cleaned. Made a set of torque plates to properly bore and hone the cylinders with the head studs. These cylinders distort as much as .0015in when stressed. #astonmartin #vantage #astonmartinvantage #astongram #astonmartinlagonda #engineering #engine #enginerebuild #turbo #builtforboost #cpcarrillo #aclbearings #arpbolts #enginebuilder #pavelsracingengines #pavelspec #problemsolved #ilovemyjob

Christmas morning πŸŽ„,20 degree❄️ and not ran since September cold start, starts right up 😎😎🀘🏻🀘🏻#neon #dodge #srt #srt4 #srt4junkies #boost #turbo #agp #bwoodyperformance #prothanebushings #seiboncarbonfiber #bcracing #brideseats #sparcousa #mishimoto #pavelsracingengines #extremeturbosystems #aem #streetscene815

This is THE most important step to preparing any SR20 engine. I made this fixture years ago using an old lifter and a dial indicator. After a valve job the valve tip heights will vary. This causes the rocker to lay 'angled/crooked' on the valve tips. This can cause abnormal rocker pad/lobe wear and thrown rockers. I measure valve tip height and grind them to be within .0010in difference. The final adjustment can be done with the shims. I don't use rocker arm stoppers and can rev to 8000rpm, of course, with proper valve springs. It is a tedious job but absolutely necessary for reliability. #pavelsracingengines #pavelspec #enginebuilder #nissan #sr20det #blueprinting #enginerebuild #makingtools #drift #sr20 #drift #problemsolved #ilovemyjob

I found Aston Martin engine secret: active ring lands!!! This Aston Martin Vantage 4.3L V8 engine came in for service with low compression and misfire complaint. Three cracked pistons and one 'money shot'. Tuner said they didn't see anything leaner than 12.0 AFR on this turbocharged Vantage. #pavelsracingengines #pavelspec #astonmartin #vantage #enginefailure #enginerebuild #oops #astongram #instacar #carsofinstagram

Last night, I put the newly-made fixture to use. A couple of VF39 housings bored out and saved. Spinning the housing at 500rpm feels safe! Happy with the work time and surface finish. #pavelsracingengines #pavelspec #turbo #turborebuild #turboupgrade #billetcompressorwheel #ihi #vf39 #subaru #impreza #wrx #sti #ej257 #machinist #enginebuilder #lathe #manualmachining

Made this tool for clamping IHI compressor housings for lathe work. Before I would clamp just the housing by about 2mm step in a three-jaw chuck. High spindle speed was not an option and chatter also present. I made this fixture from a 2.5in bar of 6061 Al. Two step manual lathe operation. The compressor seal plate was measured with a Tessa three-point internal micrometer and the centering boss made with precise slip fit. Hindsight, I should have made it with a shrink fit, heated up the seal plate, and installed it since it will never come off. Third operation was manual mill for drilling and tapping M6-1.0 threads. I installed lock washers under class 10.9 bolts. Normally a turbo doesn't spin or vibrate. Now I can really spin the comp housing for boring operation and modifications. Last few pictures show an aluminum ring press-fit onto the inlet. The housing will be machined with a radius, blending the insert with the OEM casting to create a 3 inch velocity stack on the intake. We'll see if it's worth any performance on the dyno. Next project: Garrett turbo speed sensor install on the IHI :) #pavelsracingengines #pavelspec #turbo #turborebuild #turboupgrade #subaru #impreza #wrx #sti #ihiturbo #vf39 #vf43 #vf48 #turbobygarrett #turbospeedsensor #machining #lathe #mill #manualmachinist

Before and after of the Nissan Skyline R32 RB26 engine. The engine suffered a massive rod bearing failure. Cleaning the pan was tricky due to the front differential. The diff was disassembled and everything thoroughly cleaned. #pavelsracingengines #pavelspec #nissan #skyline #r32 #rb26 #enginerebuild #enginebuilder #problemsolved

Received a set of brand new set of billet camshafts from a customer for his 2013 STI engine. One camshaft was binding in the cylinder head. Journal measuring revealed .0005-.0007in larger journals and .0070in runout, aka bent cam. Contacted the manufacturer and they replaced it. Lesson: if you don't check, you don't know. Check and inspect everything! #subaru #impreza #sti #ej257 #inspection #qualitycontrol #problemsolved #pavelsracingengines

A while ago I machined these pistons for the BMW e30 M3 S14B23 engine. Readily available pistons for the S14B23 come either as 13.5 or 8.5 compression ratio. The customer from Florida wanted 11.0 compression pistons for a mild performance rebuild. The domes were machined to meet customer's needs. I'm happy with the finish considering it was done on a manual lathe. #pavelsracingengines #pavelspec #bmw #e30m3 #s14 #forgedpistons #machining #lathe #s14b23 #problemsolved #ilovemyjob

My friend is running this e30 M3 at Road America. I helped with the engine build and my oil pump drive and forged piston design is in this thing. About to run another session, take tire temps/pressures, and make necessary changes. #pavelsracingengines #pavelspec #bmw #e30 #m3 #s14b23 #dtm #warsteiner #roadamerica #vintagecar #vintageracing

Another SR20 block ready for assembly. This engine suffered a broken ring land on piston #2 and upon disassembly and inspection, rod bearings on #3 were about to spin. Luckily crank was not damaged. +0.5mm overbore for custom coated pistons, Manley forged rods, ACL Race bearings, and ARP fasteners will make for one reliable engine. Block was bore and honed with a torque plate. Note these custom forged pistons made using a strutted forging. This allows for narrow pin boss spacing and 2.000in, lightweight pins, while reducing overall piston weight and increased rigidity compared to the "typical" offerings for this engine. Pistons also have lateral gas ports. #pavelsracingengines #pavelspec #nissan #sr20det #driftcar #manleyrods #forgedpistons #forgedrods #aclbearings #arpstuds #enginebuilder #enginerebuild #problemsolved #ilovemyjob

Sent out this Subaru rotating assembly kit to a customer in New Mexico who is building a Lola T70 Mk2 spider kit car with a Subaru EJ22T closed block and EJ205 heads. This is a EJ257 79mm crankshaft modified to fit EJ22T block and rebalanced. Manley rods were weight-matched, rod bearing clearances set, and rod bolts tightened using a stretch gauge. The pistons are our custom design in 97.5mm bore and correct compression height for 79mm stroke crankshaft. This makes the engine 2360cc displacement. Piston forging was selected to have a tight fit on the pin end. Pistons also machined with lateral gas ports in the top ring. We use 2.000in tool-steel pins. The pistons are coated on the skirts and crowns. #pavelsracingengines #pavelspec #subaru #ej22t #ej205 #sti #forgedpistons #forgedrods #manleyrods #blueprinted #enginerebuild #enginebuilder #lola #lolat70 #lolat70spyder

Finished this e36 M3 s52b32us shortblock. OEM rod honed with ARP bolts. Pistons cleaned up and skirt teflon coated. King XPG main bearings. PRE ACL Race rod bearings. Rods and pistons weight matched to within 0.5 grams as a set. Crankshaft polished and balanced. Block also painted a nice gloss black. #enginebuilder #enginerebuild #bmw #e36 #m3 #s52b32 #blueprinted #ilovemyjob #pavelsracingengines #pavelspec #problemsolved
