You wanted the big exhaust housing for top end power and power curve that does not drop off on high rpms, APS engineered, designed and manufactured it and we got it

You also wanted the ultimate in boost control and ability to run high boost at lower RPMs and lower gears while less on top end and higher gears. Well the SR56 comes with the hardware, Forge wastegate actuator!!! (Forge nuff said ) Combine the Forge actuator with one of the better top of the line electronic boost controller solutions in the market and see how its like to have the exact boost pressure you like when you want it

Technical information and specs to follow. We just had another SR55 equiped 2.5 liter STi trap 120 we can't wait to see what this bad boy can do

Enjoy the pics







Cheers

Strange....the turbo shown actually has SR56 stamped on the side, but the APS website only lists an 'SR57' !!
Looks like an SR55 with an uprated Forge actuator to better control boost.
Wonder if there are any other differences?

Just checked APS' website. Apparently, the SR56 is already "obsolete" because they now list an SR57 and make no mention of the SR56.

SR56= upgraded SR55. The most significant elements are the larger A/R turbine housing and proprietary Forge billet actuator.


However, you have a choice. Current stock released is with a 60 mm compressor inlet hose connection, (which is what APS SR series turbochargers have always had, stock is 55mm) as a SR56; or the optional upgrade 76.2 mm. (3) as a SR57.


No difference in price to each other, or the SR55.

Whichever compressor housing is NOT chosen, will be offered as a loose part for an MSRP of $$??, not released as of yet.

More concrete & definitive information will come shortly through APS web site.

Exhaust housing looks like the one from the VF39--not very big.

For $2100 you can get any garrett turbo you want, rotated with an external wastegate, AND a new uppipe and downpipe.

the perrin kit requires a T31 exhaust housing, which can be had in GT flavors, and the WBR kit uses a conical discharge GT turbo. Both are $2500 but include an intake and MAF housing.

To anyone who can read compressor maps, how does the SR56 fair? I'm looking for a stock mount turbo and this is the largest with a 2.4 inlet.

How do you like your 35r compared to the SR55? How does it spool compared to the sr55? and also your power?
