View Full Version : Who has built their block? kaos200 10-01-2001, 12:49 AM I wondering who has built up their Subaru block? what kind of pistons/rods did you use? and what work was done to it? 8Complex 10-01-2001, 04:47 AM Rebuilt to stock, but thats about it. Haven't gotten to build the motor yet as I haven't been able to even get the car running for long enough to warrant it yet. :-/ AaronB 10-01-2001, 09:32 AM Wiesco Pistons (8.5:1) required slight overbore. Pauter Rods Total Seal rings All new stock valves. Stock crank. Nothing was really done to the head. Most of the work that was done was to repair the damage the stock piston fragments created. Aaron http://www.azscooby.com http://www.scoobymods.com outback motorsports 10-01-2001, 02:09 PM we've built 2.5 turbo w/pauter and outback motorsports rods ,6 diff. piston config. for 2.5 turbo. 2.0 turbo 20 psi, spearco intercoolers,garret turbos, you name it .see ya steve, Kcz 10-01-2001, 02:19 PM Mine has Pauter rods, Cobb spec JE forged pistons 9:1, 100mm bore and cams. kaos200 10-01-2001, 08:05 PM What noises do they make if any? tom@kartboy 10-01-2001, 09:34 PM kaos200 What noises do they make if any? it shouldnt make any abnormal noises what are you hearing? tom@kartboy kaos200 10-01-2001, 09:37 PM what do you have Tom? how about noises when breaking in? Im still going through that:) tom@kartboy 10-01-2001, 09:52 PM kian i still have a stock motor but i 've built countless racing motors from topfuel drag cars to 125 shifterkart ones. no noise is good noise IMHO again whatcha hearing? tom@kartboy.com Kcz 10-02-2001, 12:01 AM My engine sounds like a deisel, and Cobb says it's one of the most quite 2.5 they have heard after forged pistons. Jay_UK 10-02-2001, 08:55 AM The noise could be several things... Piston slap (to large clearance) Valve train noise (need regapping/shimming) Main/big/small end clearances too large Most likely piston slap..... most forgies have to run more clearance due to their expansion characteristics.. when they are cold, they can tend to slap.. but the noise should go away. Again.. the clearance varies from make/type of piston to another. Like Tom says... no noise is good noise :D J. AaronB 10-02-2001, 09:31 AM Originally posted by kaos200 What noises do they make if any? On cold starts it sounds like a poorly tuned diesel. Once the pistons warm up, then it just sounds like a normal diesel, but I am 90% sure almost all my post-warmup noise is just valve-train noise.
