Below are 2 pics showing part numbers/factory domestic info

The Mother of all Holset list has to be downloaded as it is too large and beyond the limit of what the site can handle (3,000 characters). The Mother of all list contains Holsets domestic and import part numbers, model, oem, etc.

RS E9 turbo part number 1515A059 (approx cost 250,000 yen from Mitsi Japan). *Warning* There are reports of RS magnesium compressor wheel failing if boosted above stock boost.

More Evo 9 Turbo info:
... * New more efficient & larger Compressor preventing compressor surge
... * Better pump gas efficiency
... * Turbine Nozzle Area (cm2) = Large 10.5 Hotside (single flapper)
... * Improve actuator design

 

Mitsubishi TURBINE A/R reference. I do not know if they reference to others (ie Holset)

Turbine housing areas:

3 cm2 = 0.14 A/R
4 cm2 = 0.23 A/R
5 cm2 = 0.32 A/R
6 cm2 = 0.41 A/R
7 cm2 = 0.49 A/R
8 cm2 = 0.57 A/R
9 cm2 = 0.65 A/R
10 cm2 = 0.73 A/R
11 cm2 = 0.81 A/R
12 cm2 = 0.89 A/R
14 cm2 = 0.97 A/R
15 cm2 = 1.05 A/R
16 cm2 = 1.13 A/R
17 cm2 = 1.29 A/R
19 cm2 = 1.37 A/R
20 cm2 = 1.45 A/R
21 cm2 = 1.53 A/R
22 cm2 = 1.61 A/R
23 cm2 = 1.69 A/R
24 cm2 = 1.77 A/R
25 cm2 = 1.85 A/R

 

Have to keep in mind that any reference like this is only accurate for a specific turbine wheel diameter.

 

This is a GREAT resource! This is the kind of information that really makes the site wonderful.

 

I've been searching for this info for a long time! Great info, thanks!

 

In terms of the cm=ar the numbers posted are very generic and should be used to figure out what you have on your car.

For the holsets a stock hx35 with a 12cm housing is less then a .60ar The numbers we were able to get from vendors and people that work in the company placed the number closer to .55

I made the mistake of seeing a list like that at one point and found out the hard/expensive way that the exhaust housing on these will choke a hi-reving motor at alot of psi.

 

I have another list in reference to Holset 35 series. The housing are relative to the turbo model. The holset 12 is just about right for a 2.3build but some use 16-18 with a split scroll header for quicker boost and more overall flow

when i was looking at using a holset, i had to dig around for a LONG LONG time to find this stuff. Maybe it'll be of use to somebody looking to use one.

 

Already Stickied.. thanks for the info

 

Don't know if anyone would be interested, but I have the compressor map for the HT60 Holset.

 

Post it up

 

I know back when I first went turbo (2002?) Compressor maps were hard to find for holestets!

 

thx
