T3 VL Turbo for R33 GTS-T?

[BATMBL]

Hi guys,

Just wondering whether a secondhand T3 VL turbo for $500 is worth the upgrade on my R33 GTST Series 2? As its supposed to bolt straight on, since R33's have T3 flanges but T28 turbos...

Anyone know any stats on these turbos? Is it a worthwhile mod to get more hp than stock turbo?

cheers

Yes I would also like to know this. Do they have ceramic wheels or anything like that?

i think there only a little bigger,there about the same size as the vg30 turbo,so for the rb25 its not really worth it. put that 500 towards a bigger garret turbo or something along those lines

I would think the RB25 Turbo would be a better bet over a vg30 turbo due to the newer tech and better efficiency.

?!?

I noticed with the VG30BB it wasn't really that much better but around 1000rpm laggier compared to the standard RB20DET Terd. Overall it was slower on the road and still dropped boost.

Apparently the R33 & R34 turbo's don't drop boost.

VL turbo T03 unit's are way cool. They are steel wheel from the factory and on the RB30ET can make over 300kw.

300kws with the standard turbo? i havnt heard that be4,u sure u dont mean a t3/t4?

[slip]

300rwkw with a standard t3........ maybe at the flywheel?

323rwkw has been done on an rb30et with a t3/4 + custom manifolds etc. t3/4 would be a better option.

[Cubes]

Thats roughly the same as a RB25DET Turbo though.

Even if it were to make 300kw the RB25DET will spool earlier and make around the same power.

It may end up being slower with a RB30ET Turbo compared to the RB25DET turbo making similiar power due to the vl turbo being laggier.

im not too sure about 300rwkw with a stndrd t3.

i have around 215rwkw , still using the t3 though it has been hifloe'd , not using t4 internals but.

i think with tuning capabilities of a skyline compared to the vl , the t3 would go nicely on it.

matched with correct exhaust and cooler blah blah blah.

with a hiflo t3 ur garaunteed to make more power.

they are oil and water cooler , steel wheels but not bb.

How are they lag wise?

A standard RB25DET Turbo will make 210rwkw on a RB25DET.

I wouldn't really bother with the VL as it will probably lag a little more than the standard unit and on the street it will be slower.

OVL-747 origionally 382 GZV - 4 Door R33 said 300kw which is at the flywheel then slip sliped in the rwkw which is around 400kw at the flywheel.

T3 will get you around the 200-220 rwkw mark in a hi-flowed form. And they are NOT ceramic stock.

They run out of efficiency though thats why people hi-flow them and it works realy well.

anymore than that and that's where you get the much loved t3/4 combo's and they produce some serious power.

good for 11-10 sec passes.

There are a million different combo's with housings/wheels that people have played with.

lag wise tough... i've got a t04E and i get FULL boost at 4500 but it makes boost from 3500 (yes mega lag) but that's totally unmodified. Also to mention i got the 'R' extractors

It would suit a 3ltr perfect but i'm gonna play with bits eventually to get it to around 4000-4200.

[Zdenko]

so a T3 hi flowed on an rb25det would make a good little upgrade???

[R31Nismoid]

depending on price... And if you exisiting one is a little tired and you get a blown T3 and the Hi-flow it (which basically makes it liek new)

You live in Altona... so there will be LOTS of blown/new ones and very cheap LOL

Dunno how they go holding boost till 7000rpm though as VL's don't rev that high... but then the produce more exhaust... ?!?!?!

But definately get a good boost controller. I had a Calais Trubo a while back. It had a t3 hi-flo. Went like the stink

It kept spiking all the time thoguh as it just had a bleed valve so it was all over the place and boost didn't hold properly.

With a good one there would be nice results.

But maybe hi-flo your exisiting one ?

I seeing a few do that now... few threads about it now too lately.

[Zdenko]

lol @ altona

hahahah

yeh mite have a think about it

thanks

Basically BATMBL the T3 from a VL isn't an upgrade.

Make 200+rwkw on the standard turbo first then upgrade to a larger turbo after then. The T3 from a VL is older technology hence it wont be as efficient at your desired boost levels and it will make boost later.

For example:

The VG30BB Turbo, it has a larger exhaust housing however it has a smaller compressor than the RB25DET Turbo. It also drops boost where as the RB25DET Item doesn't.

It isn't an upgrade.. Save your money and spend the $500 towards engine management.

[OVL-747]

joel - lag wise it is very good , well on my car at least.

putting it on a smaller capacity engine then yeah id say itd increase lag a bit.

what size ex housings are on the 25det?

as you said save his cash and put it towards engine management , thatll get him more hp too , so either way he is a winner

i had a vl turbo befor for about 3years thrashing on 15+ psi head went twice turbo was imac. i dont think that the wheels are ceramic cya
