$120.00. Proper positioning is maintained through the use of a wave washer located between the rocker shaft arm and rocker arm shaft support. To overcome this situation and to contribute to the total reduction of friction loss, 1997 and later SOHC engines have solid valve adjusters. Engine Swapping Applications: The spark plugs are specified one step colder, compared with other Sti. The hydraulic pressure of the lash adjuster must be overcome during operation and during the most critical time of engine start. Also there is EJ255 version with the increased intercooler and with maximum boost pressure 13.5 psi (0.93 bar). When swapping over the EJ20X/Y Powertrain over to these models, you have the option to use the twin-scroll turbocharger and JDM headers, up-pipe but you'll need to source/alternate a twin-scroll downpipe to fit along your current exhaust set-up or swap over the USDM Intake Manifold along with the USDM headers, up-pipe, turbocharger and use your existing exhaust set-up. to the rocker arms used in the previous EJ20G. Because they are non-interference engines, if the timing belt fails, the engine of the models up to 1995 will not be damaged. The pump remained the same, so it is designed to handle a fast rack. For an EJ255 and EJ257, all the block needs is a set of forged pistons. There are no TGV's, the intake manifold is one piece.

This eliminates the clearance that was available between the piston at TDC and the fully opened valve. The piston skirt was reshaped and the piston weight was reduced by approximately 100 g (3.5 oz). As well, the EJ25D from the 1999 Outback is a one-year only factory hybrid, which uses the phase 2 case halves with an 8 bolt bell housing (as opposed to the 4 bolt bell housing used until 1998), uses a phase 2 crankshaft and rods with rod journals, but retains the same pistons as the 1997-1998 variant to maintain the same compression ratio. This engine uses the same shortblock and heads as the EJ257 in US 04-06 STI. It came with an aluminium alloy block with 92 mm (3.62 in) bores – with cast iron cylinder liners – and a 75 mm (2.95 in) stroke for a capacity of 498.6 cc (30.43 cu in) per cylinder, with thicker cylinder walls than EJ25.

All DOHC and 1998-up SOHC EJ engines are interference engines, if the timing belt fails the valves will likely be damaged. Another source of high engine friction is the valve train. The exhaust is completely different/incompatible with the USDM WRX/Sti, all the way from the header to the downpipe. SOHC Easy Returns. While Subaru has not provided a direct list of revisions between the EJ251 and less common EJ252, there is some degree of information suggesting the EJ252 was simply an alternate version of the EJ251 made to meet California Emissions Standards when the SOHC EJ engines were first introduced in North America.
