turbo opinions and advice

[colin777]

hey guys im lookin at a turbo its a garrett gt4202r
Compressor Specs:
-Inducer = 74.3mm
-Exducer = 102.3mm
-Trim = 53
-AR = 0.60

Turbine Specs:
-Wheel dia = 82mm
-Trim = 84
-R = 1.05

just wondering does anyone have one of these, and what kind of spool up time and suitable mods ie injectors
my engine is street ported and have 4x850s. was lookin to go time attack
all opinions valued

You wouldnt need GT4202R turbo for that setup..

That is a huge turbo, and will need big injectors to make full power..
And some huge porting work.

[colin777]

well the porting i cant change but injector setup is easliy changed like 1640 secondaries with a supra fuel pump and fpr, im lookin for 550 at flywheel or there abouts

Im going to run that turbo, with the same exhaust housing 1.05.

And I have a PP engine and 6 1680cc injectors...:yes


So if I where u I would run some thing like the Garrett T04Z.

Senb Jan Tore a message, he who are building the 4 rotor.
He used that turbo on his car last year running Time attack here in Norway.

well the main aspect is time attack suitability for spooling and acceleration, what about apexi rx8, gt35r. what is the hks t51r kai like??

gt35r would be good to..

The hks t51r would be to big again, that is more like the GT42 turbo only more expensive..
I dont know anything about the apexi turbos.

Do u have any in UK that can rebuild the hks or apexi turbos?
We don`t here in Norway, so it`s very expensive to get the rebuildt.

[colin777]

not sure, maybe dragon or reworx do. wgt also
think i might keep an eye out for a gt35r or a to4z
whats the top horses i can epect with a street port with 2x850s and 2x1680s at 1.2bars??

Garrett T60-1 (aka T04S) rated good for upto 500-550hp fly... good spool up and excellent mid to top end power, ideal for track use..... I\'m selling the complete kit here http://www.mazdarotaryclub.com/forums/showthread.php?t=56543 :wiggle

At 1.2 bar on the T60-1 I was just shy of 500hp on a mild streetport

[colin777]

whta kind of fuel set up was that kash, and who mapped

[Kash_]

Setup was mild streetport, 550cc primaries, 1600cc secondaries, aeromotive fpr... mapped by Jaydee who can vouch for how good the car moves

[colin777]

whats the difference between to4z and s

[Kash_]

tbh the GT42 will be too big for your setup and too laggy

[Kash_]

t04z has a slighty bigger wheel then the t04s.... but both good for 500+ hp... t04z are £££\'s!
