sr20det turbos?? modified mag
alright i know i should search this but its lik 6am here and i need to go to bed
i just looked through my issue of modified and they say that the S14 Sr20det uses a larer T28 rather than the T25 from the S13, ok i might be wrong as its too late for me to think proper, but isn't it only the S15 that get the better turbo the extra 15hp rate is because of VVT or something, and the picture in the mag looks like the S13 blacktop, not the notchtop you should see they have a guide to installing SR20det this issue lol

props for 3 AM...
---Silvia 95-98--- Displacement: 1998cc (2.0 liter) Horsepower: 220hp at 6000rpm Torque: 203 ft/lbs at 4800rpm Bore and stroke: 86mm x 86mm Compression: 8.5 : 1 Turbo specs: Compressor: T-28, 60 trim 60 mm BCI-1 compressor in T-04B housing Turbine: T-25, 62 trim 53.8mm 0.64 A/R turbine housing. Center Section: Ball Bearing Variable valve timing system and a different turbo are the significant changes from the S13 SR20DET engines. S14 uses 'low port' intake design vs. S13 'high port' design. Performance: The stock turbo will be safe to 13-15 psi. After that, the turbo is past its efficiency range, and power increases will fall off and are not worth the risk of turbo damage. The engine should produce 250-260 RWHP at safe boost. T25/T28
