Project Supra T51 KAI BB

[Guest Terry S]

Thank's for comments.

Below a bit of info on turbo-

 

''While HKS does use Garret for their turbo assembly, the units are designed by a joint venture between the two firms.The difference with the HKS version and the Garrett version is the wheel combinations that HKS uses are proprietary to HKS, and cannot be ordered through Garrett directly, although you can often get close. This the same deal with GReddy/Trust turbos and Mitsubishi, Blitz and KKK, and Power Enterprise and Apex and IHI. While all must rely on the actual manufacturer of the turbo center sections for the general supply, the specs each offers are unique to that particular manufacturer.''

Nice one, the yanks luv them.

No worries, so if you ever lose a wheel, dont let someone try and shaft you!

Just read all 9 pages. Good thread. You'll have to post some vids up for us to see it in action. I just hope your stock internals last.

I would tend to agree with the last comment. I have/had about 500bhp at the wheels with a hks t51r and what a sound it made when it came on song it was like a jet engine. Loads of power very suddenly making it able to wheel spin in fourth in the dry! But mine was on standard internals and i lost a rod bolt totalling the engine. Worth upgrading i would say

great results ash that is a big turbo

Nice to see on here Paul, how's your pockit rockit?

Totally agree guys, but our engines are very underestimated, the yanks have proved some great numbers on power and reliability. All points to good fueling and mapping.

 

Supradupra, good to now we have another HKS T51r on board, sorry to here about the rod bolt.

Whats your set up, fueling, management etc.

[paul gtir]

hi ash its in the garage i have got to the stage now that i have had enough of it going wrong all the time qauife number 2 just come through the gearbox casing and dont wont a ppg dog box so i am just going to put it in the garage and use it at weekends and buy a supra for everyday use going to tune it to around 500bhp i no it wont be a match for the r but atleast it will be reliable and just sick of a few pepole on the oc theres only a few good pepole left on there now most are idiots that get on your nerves they always no best about the cars and infact they no jack all

 

like ash said a car will only perform as well as its mapped if somebody was to map it crap it would 2 minutes

[Guest Bijal]

Looks that way, but not the type you are thinking of Adam

 

There are two specs on the HKS T51 ( numbers are chosen to confuse IMHO) one is just over a 70mm wheel, the other around a 74mm.

 

Basically they are Garrett GT42R's rebaged.

 

 

they are not garrett gt42r's rebadged. they are totaly different. the hks version is EXTREMELY light weight and far advanced design. i cannot enphasise that enough.

Can you explain the differences other than the compressor housing please.

yes we all know they are garret based but there are still massive differences on specs, design and technology. not flog offs from gerretts.

 

hks spend millions on testing and developemnt and give their specs and order to garrett to manufacture and garrett are sworn to their secrecy on that spec.

 

yes, they have the same compressor housing but the internal design and and the MASSIVE weight differences are their to be seen only through experience working with them.

 

the spool charectoristics are totaly different, the hks has a totaly different sound to any other turbo we know and also the way it spools too.

 

you need to physicaly hold an hks signature series turbo and compare the way they spool to know the difference.

 

we have done the testing ourself thats why we know and are amazed at the differences compared to the "equivalent" garrett or even BL range.

[Guest Terry S]

But what are the actual differences. Look at the wheel specs, they are the same. The DBB Cartridge is the same. I love to learn about turbos so would appreciate some technical facts to back the statement up please mate.

 

Do you have a dyno of a T51 against a GT4294R on the same car? That would be a great help:thumbs:

[Guest Usmann A]

Ok official T51R specs..

 

T51 R KAI (dbb or not)

Comp Trim:56

Comp Inducer(mm): 70.3mm

Comp Major: 94mm

Turbine Trime: 76mm

Turbine Major: 82mm

Turbine Exducer: 71.4mm

A/R: 1.00

 

T51R SPL

Comp Trim: 56

Comp Inducer: 76.5mm

Comp Major: 102.2mm

Turbine Trim: 76

Turbine Major: 82

Turbine exducer: 71.4mm

A/R:1.00

 

Ok, whats so special about them FM racing? The fact that they have another similar solution to anti-surge housing? Ok HKS spend alot of money on R&D, what special materials do they use then on thier wheels, and bearings? If they where that good why didnt they get turbocharger production themselves, like they make thier own pistons,etc.And keep the spec secret.

 

Think logically, HKS custom garrett to make thier turbos, OK.

All HKS specs are pully published.

All Garret specs are fully published.

Now from what i can see apart from the turbine wheel trim, they are identical.

 

 

 

Just HKS make one little change, drill some holes and put a badge on it, its value doubles.(sorry but the tuning world is full of suprises)

 

Also, id like to see logs like Terry says and when you say wieght? hav you weighed the wheels?

 

thanks

[paul gtir]

good point a lot of top brands are not actauly made by them for instance look at hks rods who make,s them well its not hks and hks is not even stamped on them.

olso look at jun headstuds they are made by arp

if you do your resarch you will this infomation out

 

 

sorry to take over ash and this should be discused on a new thread

[Guest Usmann A]

I am sure HKS make thier own pistons, etc, as somone went to thier factory and saw it. IIRC.

 

Yes sorry Ash this should be discussed in a different thread.

[Nic]

Just because a part is made by another company, doesn't necessarily mean it is exactly the same design and spec. Yes some products get rebranded, but in other cases the products are designed/engineered 'in house' by the company (usually in conjunction with the manufacturer) and then manufactured by another company. It would not feasible to set up your own production for every single product in your brand, so you out source the manufacturing to a specialist manufacturer. It's no different to any other big branded consumer products we buy everyday.

 

In this particular case, I've no idea if it is the same product or completely different, knowing hKS I would suspect that it will be their own design and not just a rebadged off the shelf product, but that's purely a guess based on the other products in their range.

[Guest Terry S]

Guys I am not saying it is EXACTLY the same. HKS arent daft by a long stretch they do some funky housings for the turbos just look at the T04Z ( which appears to be basically a GT40-67R) with the anti surge design compared with Garretts anti surge housing, but I am pretty sure that change is for looks but I might be wrong. What I am saying is they are virtually identical to off the shelf Garrett offerings. I would love to know what other changes there are if any and welcome any tech input into the finer details between Garrett and HKS

[MONKEYmark]

heres a few other gt42`s

 

GT-42 70T 950 1.15

I was mainly replying to Paul's post above.

 

I'll see if I can find any more info on the T04Z housig design, I suspect my lack of knowledge and the language problems may get in the way though.

[Guest Terry S]

Yeah I know mate, just thought I would clarify.

[garetheves]

and there's me thinking a turbo is a turbo.

ok, just wait and be patient. i have 6 supras here, all single turbos with a mixture of turbos from trust, hks, garrett AND Boost Logic's setup.

 

when i have time (early part of next week) i will post pics on a digital scale of at least minimum 2-3 turbos. see the weight difference compared to the hks t51r.

 

to a hardcore enthusiast this would be serious shit. but to everyday people who are not too bothered they dont mind an "equivelent" if you know what i mean.

 

bijal

[AshBhp]

when you say weight? hav you weighed the wheels?

 

thanks

 

 

Have you guys actually held a HKS T51? trust me you will be shocked.

 

I think we need to do a weigh in, lol.

[AshBhp]

I wish i had a £1 for every view.
