This is a Honda Forum.. I'll give you a start, with some reviews, but look for me on the Club Lexus and Silvia.net for better info next time. These are not really the best choice AT ALL for a Honda motor B-series with its higher flowing head design.


GARRETT T25
They are from the small series of turbochargers specifically engineered for original-equipment small-capacity engines, have their roots in the ET Pulsar, and culminate in a 'twin' application on the 300ZX twin-turbo VG30DETT. In single form, they are not recommended for performance applications.
Car of Origin: Nissan S13 Silvia/180SX
Engine: CA18DET
Flange: Four-bolt; it fits most Nissan four-cylinder turbo engines
Max. Power Rating: Approximately 130kW (128hp)
Max. Boost: 1.0bar (14.5psi)
Cover Size: Exhaust 0.48 AR, compressor 0.49 AR
Comments: A small and reasonably ineffiecient turbocharger that should only really be used as a straight fit for an existing CA18DET engine to replace a failed unit. It's not recommended as a bolt-on for a normally aspirated engine of more than 1600cc.

Also the original Nissan Garrett T25 is used:

Car of Origin: Nissan PS13 Silvia/180SX
Engine: SR20DET
Flange: Same as above
Max. Power Rating: Approximately 160kW (157Hp)
Max. Boost: 1.2bar (17.4psi)
Cover Size: Exhaust 0.64 AR, compressor 0.60 AR
Comments: Improved flowing version of the CA18DET turbo makes it a great straight-fit bolt-on to the CA series, but becomes borderline on even a lightly modified SR20 engine. That the S14 series of cars moved to using a bigger T28-style unit is testimony to this.

Here's the T28 for different year Silvia..

GARRETT T28
The next size up from the T25, the T28 series of turbochargers are more serious items. They are used in twin form on the Nissan Skyline GT-R and singularly on the Pulsar GTi-R, S14 and S15 series Silva/200SX. They make a decent upgrade for the S13 series of cars when more than 150kW are reliably expected to be produced.
Car of Origin: Nissan S14 200SX pre-1996, Nissan S14 200SX post-1996, S15
Engine: SR20DET
Flange: Four-bolt, same as the T25 series.
Max. Power Rating: Approximately 170kW (167hp)
Max. Boost: 1.2bar (17.4psi)
Cover Size: Exhaust 0.64 AR, compressor 0.60 AR
Comments: The ultimate OE bolt-up to the S13 series of cars, the best part is that it bolts straight on. A good little all-round mid-range turbocharger that has proven itself to be extremely reliable in service.

Based upon Trim, compressor wheel, and diameter measurements, Not all T25s were created equal.


In order of size rate smallest to largest of the T25 turbos.

Did you read ANY of my comments posted in my last post? It gives you a direction in terms of how to upgrade for the 300zx by TELLING you what the 300zx uses..

Not only were you spoon-fed, you got the whole 3 course meal

ELSpool

so, yes, it's the best OEM upgrade out of the T25 flanged OEM nissan's turbos.

As an FYI, the Nissan Pulsar GTi-R T28 would be the biggest O.E. T28, as it has the largest turbine housing a/r at .86. It does have the same compressor as the S15 Silvia, however.

You would need "JDM" cast HKS discharge pipes, as JDM Fairladies use the standard T25 5 bolt turbine discharge flange, while the U.S. version is 4.

Your buddy may want to check out JimwolfTechnologies.

pm me if I can help out any further.

Sorry the fairldy z 89 uses 4 bolt man we just did downpipes

</TD></TR></TABLE> The s14 has a T-28 as well as the s15, s15 is typically BB whilst the s14's commonly have plain bearing turbos with some later variants using the BB turbo. Your KW to HP conversion is messed up 170kws = 227 hp.

The gt28r or the BB s15 turbo is good for 300whp, plain bearing S14 T28 will see about 280whp.

the car ran a 13.2 with the stock turbos and stock cat back so i think with some s14's and 3" exhaust and some port work the car will be in the mid 12's now
