Series 1.5 Turbo

[Nismo_God]

Hi,

i have owned a R33 S2 and know the limits to that turbo.

what turbo is found in a 95 S1.5?

whats the limit of a S1 turbo? as in psi and expected kw.

searched but cant find anything.

cheers

I believe the S1.5 has the S2 turbo in it. But as far as i'm aware it doesnt really matter if you have the nylon or ceramic they will both fall apart once boost is increased to 12 or more PSI.

Its kind of the luck of the draw. I'm personally running 12PSI on a 95 S1.5 (spikes out to 1 bar sometimes as im using a bleed valve not a boost controller as such) and have been for some months with no issues.

yea series 1.5 are series 2 motors...and turboes....i am running 7psi and have a flick switch for 18psi but my turbo has been ball bearing and high flowed and has a steel turbine

There is no such thing as a series 1.5.

All the 33 range of GTST's have the same safe boost value of 12psi. 14 is ok but pushing it, 16 and you're likely to break it.

S1/S2 - same in terms of what the can/cant do for all intents and purposes

Same limitations, same power outputs etc

I ran a series 1 turbo @ 18psi for bout 18months on my old rb20. Never had a probably. when i pulled the turbo off it seemed happy lol. little bit of oil, minimal shaft play still and no weird bearing noises or anything. Probably luck though.

RB20 and RB25 is different.

You can get away running more boost on the RB20. Search for further details

What makes you say that? Quite obviously there is... cause I own one. It has heaps of S2 features/parts that S1's never had.

I'm with you, there is an "in between model" I recently wrecked a S1.5 it wasnt a S2, it had S1 front end and other distinguishing features to the S1, S2 airbag wheel, S2 afm, and more, all origonal, anyways off topic Edited April 30, 2008 by madaz R33
