Hi Gents

I bought a turbo Kit for my FD in Japan at a baritgain , was advertised as a Garrett TO4E and capable of 350 - 400 HP .

When it arrived I saw it was actually a H.K.S turbo :-)

So I went on to google to look for the part number and get the specs

TurboMaster - Catalog - garrett - TO4E

Part number Aplication C.H.R.A. Service kit A/R

465633-0001 H.K.S. 408105-0327 468265-0000 0,84


I the housing is 60 and the exhaust side is 0.84

I tried to find out the wheel trim , but even with the C.H.R.A part number I get no results on google . Can anyone help me to find this out ?



My motor is still stock with stock seals , what sort of boost is safe to run and what can I expect in terms of wheel horsepower ?

My FD specs

Series 7 FD3S
Power FC
AVC-R boost controller
Greddy Elbow
Blitz SSD Blow off
Greddy Ellbow
550 primary 1680 secondaries
340 L intank pump
SARD fuel regulator
De cat
Downpipe
Greddy type LS FMIC

I plan on getting approx 350 HP on the wheels , how much boost will this require ?

On Stock sequential twins I boosted about 0.95 kg/cm and made approx 290 HP on the wheels with stock fuel system

 

its probably a 60 trim T04E with a p-trim, which are good for 350whp or so

best way to find out for sure is remove compressor cover and turbine housing and measure wheel inducers and exducers, see if they match the compressor and turbine wheels specs here:

Turbonetics Catalog

 

What kind of flange is on the back of that turbo, and what kind of downpipe do you have?

Does not look like any form of Vband to me

 

Given the size of the exhaust housing (AR 0.84) it seems to be the turbo out of FD-kit which was T04E-60. You can measure the compressor size to be more confident.

 

I removed the housing yesterday but not Shure how to correctly measure the wheel trim . The wheel has "A" and "786" stamped on it .

 

google man, use it

 

Sorry man , got it now .
My calculation turned out 57.6 for the compressor wheel .
