There is nothing wrong with the old T4 turbo.
and there is nothing wrong with the new GT turbo's ..........

but i just prefer the T4 for loads of reasons.

What do you boys think?
and why?

 

can you list some of those reasons ,, as pros over the gt's cons...

 

i prefer the gt for loads of reasons but if your not telling neither am i.

 

I would say Im a fully paid up memeber of the T4 club!

wait til you see the new one on my car

 

Major Pro has to be it's strength!! they can take so much punishment all day long and not cause any problem.

GT series are fragile to say the least!

 

I think you are insane TBH but would love to hear why the T4 is a better turbo.....

 

The GT40 car i went in that Stu was mapping had a much more gradual powerband than the bang of the T4. A Pro or a con depending on what you like.

 

The GT40 is a 700hp turbo the T4 is not, Its just like comparing a 1.6lt engine to a 2lt.

Mark

 

Yes, the point is I'm led to beleive that GTs are like this generally, I assume because they start to build small boost earlier, rather than in one go later...

 

A correctly spec'ed GT turbo set up is better there no doubt about that its a all round better turbo,
You can make the older type turbo's work well but they wont match a GT,
When you see these hybrid T4 turbo's they are now not a T4 most will swap bearing housings or but diff type/GT compressor wheels on to the back of a T4 wheel, So you cant call it a T4 but maybe a T4GT but its not a T4.

Mark

 

I like the big bang theory......that my T4 produces ie wait 6 days before life appears

 

The T4's like mine from CR turbos retain standard T4 comp and turbine wheels albeit with full roller bearing cores and modified comp housings.

 

............then hold on for dear life lol !!!

 

Im Paid Up T4 Fanatic And Still Loving In

 

Will soon be, engine went in today, just need my T4 serviced and big bang here we come

Steve

 

me 2 steve,got my head back today fully built up ready to go at long last

 

Im a new member and love mine

 

I was a full paid up member, Trev has taken over my membership in the club.

I really liked mine with inlet cam i had and once it was mapped, it wasn't so much an on and off car then.

 

Old vs new!!!
Its like a spah cosworth vs evo.
Depends on what you like & want.

 

Surely the only way to sort this one out would be, to have two cars of the same spec.
Head /CR / cams/ inlet etc.
One T4 one gt30.

 

A T4 is the biggest best and ONLY turbo for the YB in terms of reliability with 500bhp..surely enuff!

 

I debated which one to go for but after speaking to the right people then going in a low comp red top turbo'd tigra runing a gt30 there was no real contest. So progressive and strong.

 

GT series is great but VERY fragile.

 

When overheated or in general? Do they drop like vauxhall cam sensors?

 

..a GT turbo needs water cooling with no anti lag and a good oil supply filtered and 2 dump valves ideally....a T4 needs no water can cope with mild anti lag oil supply critical but less critical than GT and no dump valve (controversial!!!)

 

Soon to be done, "moonstone steve Vs miller3",

very similar spec engines bar a exhaust cam

Steve

 

Not quite as controversial as a gay black jew though as it goes??

 

steve is yours a roller bearing ?

 

Mate we so caught up in values we forgetting to live our own life...whatever we do say YOU/ME have a life to live fuck others and there views.

 

Not at the mo m8, going to speak to Vince at CR turbos and see if it can be swapped over and if i can afford it

Steve

 

Steve, Cr is a good helpful place they should sort you out.

IMA, I thought it is funny and your deffo out there dude lol.

 

I hope so m8 ive got a GT30 saph to thrash

Steve

 

i've had one for a good while and i like mine.

 

Dave, you still running a standard engine with the T4.

Steve

 

Dream on buddy

 

i've had one for a good while and i like mine.

 

This is one of my reasons..... enjoy
