T3/T4 Turbos

[Crucible]

i have a new garret t3/to4e here that has 0.6 comp and 0.64 exh but im pretty sure itll be too large for my lil 1600.

That would be quite a close to ih8tecs turbo wouldnt it? his exhaust is .63 but I think his front comp cover is TO4b cause it looked a little smaller than my cover which is T04E.

Then it goes to the big 60-1 T04S or Z compressor IIRC?? Im sure barry will correct me if Im wrong

[spencer]

what t3/t4 would you guys reccomend for a 1jz for 400hp as my twins are on the way out

[Lith]

mine goes back to STM on the 16th , thatll be the 3rd time ive been there. i only go back coz im happy with the previous tunes just a quick dyno and tidyup of fuel maps now im spooling 500rpm earlier.

Awesome - let us know how it goes

Mine is booked for about a week after that....

[flygt4]

yeah they are pretty flat out by the sounds at the moment. lots of people rushing to get ready for drag racing season it seems. plots will be posted when its said and done.

same as the one on my car

how much they going for? im keen

mine is t04e cover. your one just has different trim wheel.

I payed $700 for mine which is the same deal as bazdas. Rated at 550hp I was told.

Barry said he was doing an order for another couple of guys on here, might get a better deal through him?

[Lith]

Where did you guys get these things?? They sound really well priced - and do the numbers. Are they genuine Garrett based or one of the "others"?

To the guy with the 1J - I've got a Garrett GT3076R with .63a/r turbine housing, its a fair bit more expensive than the T3/T4s (ie, ~$2k landed) which should be tuned on my R33 GTS25t by the end of this month, I'd call it the closest BB GT-series equivalent to the 57 trim T3/T04E though should theoretically be able to make more power with better spool, and should last forever (or at least longer than the motor haha)

If you can stretch to something like that - I reckon thats the way to go, so much cooler

THe turbos I get are REALLY well priced and really under rated by alot of people. But I have proven this time and time over again that they are awesome! lol. and real damn cheap to rebuild if ever need to be. ie $135+gst for a rebuild kit.
I have not yet had to rebuild one, they seem to take a hammering even on 27psi

As I asked before - what are they? I don't think saying a GT-series is better than a T-series is underrating them. Its life. T3/T4s represent great value for money. I just wanted every bit of extra low down torque and response as mine is primarily a street car, and perhaps have an inane fetish for big BB turbos which make cool whistley noises.

The rebuilt price of T-series is fantastic, thats the only thing that had me iffy about going GT... though again - how often do you need to go through that. I've only blown a turbo once, and that was due to fun with nylon composite wheels. Yay Nissan, finding new and special ways of making turbos disintegrate!

[flygt4]

out of the blue , has anyone run either t3/t4 or tdo5 with antliag?
any idea how long they would last?


and yes BB turbos make cool whistly noises part of the reason im partial to them too.

basically they are no brand. Made in China using KKK parts to construct the cores and their own made wheels and housings, obviously copying off high names such as garret etc as why they work so well
U just gota know what copy ones are good and what ones are bad.

[CAMB01]

How do you know what ones a copy's and what ones arent?

[Lith]

Ones with Garrett on the housings are often a safe bet - at least that the housings are really Garrett. Assumption can't be made that a "copy" is bad, so its not so much of knowing if something is a copy - as knowing what is fine.

Strictly speaking Turbonetics turbos are copies of the Garrett T-series "technology" - but they have some nice bits of work put in to them to make them particularly sturdy etc. MasterPower are another outfit who use technology ultimately mimicking Garrett's T-series wheels and housings - and to my knowledge have a decent reputation.

You really need to ask around people who have had decent amounts of experience with turbos to find which ones are lemons etc. You could probably get a "lemon" from anyone - Garrett themselves even have the odd turbo they have released which are not too flash in terms of reliability and performance (GT2540R is argueably an example of that, putting a GT40 comp wheel on a shaft expecting to carry the load of a T2x series wheel).

Turbo shopping is a potential nightmare, hence the fact I personally lean towards following the "You get what you pay for" philosophy. If I was on a tighter budget, I would have got a Holset turbo myself.

The turbos i get are basically the same as turbos form masterpower out of their catalogue.
I have seen the one i get and a master power of the same turbo side by side and they are pretty much identical. Except master power haev their logo on it and the compressor nut thread is a LH which is better unlike the one i get which is a RH and can come undone if excessive amounts of anti lag is used. They can be fixed by using lock tite .

Yes thats true, I got a really good deal because the guy needed the money urgently for a wedding, I gave him my s/c pulley kit aswell so sort of balanced out even

[Crucible]

My core has a turbonetics logo on it, but its been ground off.

They must use the same turbonetics casting patterns and core boxes, At the end of the day cast iron is cast iron genuine Garret or a copy and foundrys go to great lengths to make sure their castings dont have voids and the Iron is tip top before pouring moulds.

And as for the Comp covers etc , I do pattern making and cast aluminium as a hobby and the quality is really good in my books, no voids or signs of shrinkage

Just comes down to the quality of the wheels, seals and shafts but they have proven themselves also in peoples set-ups, and like barry said they are cheap to rebuild anyway so how bad can they really be??

good bang for your buck!!!

I had a GT28 die on me after very few k's and a pretty easy life, not entirely sure if it was due to a setup problem or if it was just a "dud" turbo. I used the you get what you pay for philosophy as well as I didn't have much experience with turbo's at the time.

Now that I've found out the rebuild price (replace core and wheels) I came to the conclusion that I might as well use an un-branded copy which has been proven and it won't be such a blow to the bank account if it fails.

I've ordered a t3/4 through Bazda so will need to get a new manifold and dump pipe made, which is actually cheaper all up than the replacement garrett core!

PS is anybody after a gt28 comp housing, exhaust housing with welded up internal? Wheels may be salvagable too, will see when I get it back.
