Rb25 R33gtst Standard Turbo Specs

[tom200]

What are the spec of the standard garrett turbo?

they aren't a garrett turbo, they are a hitachi turbo.

No idea on the specs. From memory though, all I can tell you is the exhaust housing is .63.

Here's a pic shows relative size and measurements of the stock compressors for RB25 s.2 (nylon) and RB20.

The comp housings are different sizes too; larger A/R for the bigger engine.

None of the factory RB housings actually have adverstised A/R cast into them, and unless someone went to the trouble of cutting them up and doing accurate measurements it is a bit of speculation as to what A/R they are. This applies to turbine housings also, but there is some good discussion about RB and VG housing comparisons. Try doing a search on that one.

cheers
