I measured but the caliper was crazy ...even after I zero it. What is the difference from the Garrett TO4R and the Garrett HKS version?
69.30 mm/83.20mm??????? Go to known published sizes that are close?

 

The HKS casted into the compressor housing?
Seriously, the compressor wheels are standard sizes.
HKS does have special turbine wheels that are not standard Garrett.

I've heard that the compressors used by Cheapturbo and a "real" T04R are not identical and I wouldn't be surprised if the HKS and Garrett wheels weren't the same either. Law of transitivity anyone? It's more than just the measurements that make a compressor or turbine. Shape and blade count matter as well, things not easily quantifiable by calipers or visual inspection.

 

HKS uses Garrett products it's the combo's they use that make their turbos theirs.

 

Great ...I would like your opinions on this.Here is a pic of the wheel and blades.
I hope that it enlarges...after I down size as 100X100 pix it sometimes dont enlarge WTF?Shape of blade and count. Sean may know thanks.

 

The only difference between the HKS to4R kit and the To4R turbo sold by reputable turbo shops is the turbine wheel. The HKS to4R turbo comes with clipped P trim turbine wheel. But HKS also sells the To4R without clipping. So basically, there isn't much difference.

I have used and worked on HKS T04R, HKS TO4Z, and Garrett TO4R. You can trust my words.

so which one is the best out of the 3? the Z model maybe

 

The To4Z is a ball bearing To4R but it does not really spool up that much faster. I think it's a waste of money. The Garrett T04R will be the best deal.

HKS uses Garrett designed turbos . But HKS has right to certain trims . Also HKS design turbos are for heavier flow . If you keeping boost below 1.5bar, you would be better off just getting a regular off the shelf Garrett turbo. where as if you are going over that the HKS turbos would be flowing better

And i agrees with rotary extreme about the T04Z . it is not really worth the extra ... T04R or Cutback version is better bang for your buck

 

How much power you wanna make at what boost level?
I would go with the GT35R with the T04 turbine...

edit: Chucks right!


For future reference, we here at PhoenixTurbo (formerly Cheapturbo) Only sell and use Brand new, official Garrett products, as does HKS...

please let us know if you have any other questions 1-877-23-turbo

also, on a heads up, the PeakBoost VMount circuit racing turbo kit is almost nearing the end of the design phases here at Phoenix Turbo.
heres a pic of the car that it is being prototyped on

thanks

ps: mods, please email us with advertising info.

chuck, give me a call at the shop when you get a chance.

 

The result is awesome. I've got both Road Race feel + High way feel. Very impressed with the turbo. Full Boost at 4K and it's the best bang for the buck.

I used to have Greddy T78 and XS Engineering T04E before and I think T04R compatable with 13B-REW the most, IMHO.

Give Eric or Ken a call at Cheapturbo.com

They will give you a good advise.

 

Based on Majestic Turbo (http://majesticturbo.com/bb-family.html)

T04R 63-Trim Inducer is 2.62'' and Exducer is 3.31''

 

Thanks for the emails......very kind.
I bought mine from Ken several months ago.

 

I am new to this so would the HKS kit turn your twin turbo mazda rx7 into a single turbo?

 

That's correct...

It's a very expensive way of going to a single turbo though!

 

Same as a PT67, Yes??? Wheel sizes are the same again. the 67 was basiclya response by garrett to Precisions request for the wheel. Before that, I don't think they were very easy to come by, now everyone offers it. There is also a GTQ, and a GTS version, each offers ~7% more flow than its predecessor, but with comensurate lag. Like threerotors said, the turbo is awesome, and very reasonable. t can be had divided, and water cooled as well. ITS makes a front cover for it that I am going to try. My .81 housing has some porting BTW.

 

what is special about the cover?

 

yeh... is it just the anti surge housing??
