Getting A To4e Hybrid

[AntonRx7]

I am thinking of getting this turbo this is the info i got over the phone

It is from America and the brand is Inovative its a T04E hybrid. (ITS)

Compressor: 57 with .60 cover

stage 5 turbine

.48 turbine housing

turbine is made from inconl or soemthing like that (apparnetly strong and more heat resistant than the garret turbo's so he says.

umm 360degree thrust bearing and its rated to 500hp apparently

i have also got prices on getting gtr injectors resistor pack and 040 fuel pumps.

The only mods i have are a full 3inch exhaust and a front mount. Engine is stock.

Is there anything else i need? will i need a air flow meter?

i am guessing i should be able to make a little over 300hp at the wheels reasonably safetly with a good tune and all these mods just not sure if i need AFM or anything else and if the engine can stand up to it.

ANy info greatly appreciated

that would go well on a 1.8

it looks like a t3/4 highflow with an exhaust housing that is to small for a six cyl anyway

it has probably got a cosworth iconel wheel in it.(nice)

a .64 rear or larger would be sweet., very similar to the common r33 high flow.

wat sorta power could i exprect with gtr injectors and tune get me with that turbo you recon?

will i need AFM or is that only for big big HP, or do i even need injectors will fuel regulator and big pump do?

If your looking at that turbo on ebay then i wouldnt buy it....

If it is a ebay turbo do a search on "ebay turbo" and see the outcomes for youself....

If not then ill shut up....

[AntonRx7]

nah its not from ebay. its from a shop in perth called Performanz

its a ITS (inovative turbo systems) turbo from america apparntly

[Col-GTSX]

Sounds less dodgy....

Why not just go a trusted brand like 'garrett' or 'hks' is the price really low???

[alpinestars]

wouldnt u need gate,high mount manifold

[r33_racer]

ITS are reputable american company...not dodgy like the chinese ones youve been seeing around the joint. Innovative make good turbos theres another thread around here on them.

There's nothing remarkable about any of that .

57 trim 76mm T04E compressor in .60 ARR T04E cover .

Stage 5 turbine also known as a T350 in Inconel and 5 bolt .48ARR T3 turbine housing .

This thing would be pretty laggy on an RB20 .

Fred from Turbo Logic once showed me a Garrett factory hybrid T3/T04E (TA34 series in Garrett speak) which the RB20 followers in the Gong like . It used a T3 turbine in an integral gate T3 flanged .58ARR housing with a 40 trim T04E compressor in .50 ARR cover . Do a search on Garrett T31/TA34 turbos .

350hp atw would be the most id expect from that combo on about 20psi.

not bad power.

Discopotato03, That T3/T04E garret factory hybrid sounds exactly what my turbo could be which is the factory fitment on GTS-Rs.

I have never been able to find any decent info on it except from what is written about it in the homologation papers which aint much.

Did it look like this?

[Kaido_RR]

fatgts-r,

your right, stock gts-r turbos are T04e, (im not sure if they are garret or HKS, as i have seen a few for sale in japan all under HKS not garret)

[FATGTS-R]

Yeah they are T04Es but have a T3 exhaust housing with internal gate, hence a factory hybrid. And they are a Garrett item.

Just never been able to find any decent info on them.

[AntonRx7]

well this is all very confusing. think if i do it i will get the t04 over the garret 2530 as the price for the garret to get fitted will probalby end up being way too much. (the gtr injectors and tuning is gona be heaps as well)

Will i need a Z32 AFM?

and will 300-350 atw be pritty unsafe for the engine?

[AntonRx7]

oh yeah the price to get the to4 fitted is 2300 drive in drive out (set at a safe boost level as i will only have a FMIC exhaust and fuel pump untill i get the tune and injectors.

And the gt2530 will be around 2700 however the guy wasn't sure as i thinks it could cost more if he comes across troubles

i am guessing the garret is a better turbo that the to4 but supose it just comes down to how much i wana spend

[discopotato03]

FATGTS-R it looks like a T04E compressor side with the Nissan type T3 integral exhaust housing - nice manifolds those GTS-R's . The turbo could probably be recreated without too much trouble depending on wheels and trims .

cheers A .

AntonRX7 , do a search on 471182-0007 .

The first site shows a table of Ray Halls medium frame Garrett TB03/T31/TA34 turbos . At the second site (not in english) if you scroll down a bit there's a couple of decent pics of the 471182-0007 turbo that Fred reckons works well on RB20DET's . T3 flange , integral gate , 40 trim T04E compressor in .50 E housing . Turbine housing is .58 and even has a V-band exhaust outlet on it .

I know the one you saw has the large 57 trim compressor but don't forget that these are 3" or 76mm compressor wheels and its all too easy to go too big and create lag monsters which RB20's don't like . Look at FATGTS-R's pics of the compressor side , that's no huge trim wheel either . Nissan and Garrett would have had their heads together to spec the turbo for a limited production homologation special car (R31 GTS-R) so its worth a close look .

Personally I prefer more modern Garrett GT Ball Bearing turbos but finding something with a properly designed integral wastegate T3 flanged exhaust housing is difficult and expensive . At least that TB31 has no hard to get bits and would be cheap to service .

Let us know how it goes cheers A .

[FATGTS-R]

Discopotato03, For your information the specs I have of the turbo as stated in the Homologation papers are as follows:

Make and type: "Garrett turbo Inc. T3/TO4E"

TURBINE

Turbine wheel material: "special heat resisting alloy"

Number of blades: 11

Heights of baldes: 17.78mm +/- 0.25

IMPELLER

Number of blades: 12

Heights of blades: Larger 6, 24.69mm smaller 6, 18.2mm

There are also dimentions of entry/exits and internal dimentions of each housing but the diagrams are needed for them to make sense.

[discopotato03]

Yes homologation papers like to be specific , there was some controversy over the DJ RS500 turbos which had some "alterations" to the compressor . The scrutineers could see the difference but the measurements fit the specs .

Higher spec steel alloys are used for turbines that see prolonged use on petrol engines to cope with higher exhaust gas temperatures .

Cheers A .

[AntonRx7]

yeah i think ill just have a think about it for a bit longer and maybe try get some more prices on getting the GT2530 installed as a lot of people do have them and swear by them. It just a lot of money when i have to get gtr injectors and stuff as well but i figure no point just going small with the rb25 turbo.

how much boost with the GT turbo should i be able to run with the stock engine with front mount 040 fuel pump and exhaust? if i have injector and tune?

and if i don't have injector and tune?

i have found a dual stage boost controler (turbosmart) for 130 would this be worth getting or would the turbo's boost be controler wiht adjustable wastegate actuator do the job better than a controller?

oh one last thing i won't need the Z32 AFM with the GT will I?

thanks for all the info and helps guys much appreciated just want to try make sure i have everything sorted
