The VF23 will no doubt give you more power than a standard TD04 but you may find it a bit slow to spool up.
I have driven quite a few different cars with various standard and hybrid VF's and must say that to date.....I'm not too impressed
A better option in my opinion would be a front entry TD05. My observations have been - quicker spool up, increased torque, quieter turbo and the ability to exceed the power output of a VF23. They are also very reliable and cheap to maintain.
If you get one complete with its cooling pipes it is a direct bolt on.

It is more cost effective if you have a standard turbo to upgrade. They are standard fitment on most 94/95 cars.
Mark Aigin (Lateral Performance, see scoobyshop) can get them modified to front entry and fully overhauled so you have a virtually new unit.

I was just thinking if itīs better than the vf29 i currently run at 1,2bar/held to redline.(thinks thatīs about what it can take=
Is it slower in spool up and how much can it take??

Sorry, I don't know the VF29. The TD05 is likely to outlast your engine (mine did 
)
On most cars, the TD05 will give 1bar of boost by 3000 rpm. It will run all day at 1.5 bar boost. I have had mine to 1.8 for drag strip racing and it was fine

I ran a VF24, and had the opportunity to try a 23...which @ 1.4 bar midrange (tailing off to 1.15 at 7k) produced enough grunt for a 12.72@110 run on a proper dragway.
It's a lovely little turbo, the main difference I found was that the larger P20 exhaust housing allowed me to run more boost and advance before it started to get noisy (than with the 24).
The TD05 seems like a good turbo though...
/J - running a TD MD304 and I am *very* happy with it.

Depends on mapping, intercooler etc but recently a TD05 with a fmic, remap, 550's, 2 1/2 exhaust and intake filter made 280bhp at the wheels (AP22) which is approx 344 flywheel. That was 1.35bar midrange tailing to 1.25bar top end. A MD304 incidentally made almost exactly the same power but just took a bit longer to spool up.
A similar turbo propelled my car to a 11.8 second / 118 mph 1/4mile run........ /J

Andy - your power and quarter times doesn't add up mate. One of them is *way* off - and I suspect that'd be the slip from the dragway. 340-ish won't produce 11's, the car would have to weigh in around 1100 kg's for that.
I only got a pathetic 110 mph due to running stock 440's on stock preassure, with boost tailed off due to running out of fuel. and
Keep your mitsumaschi turbo mate.

/J My car wasn't the one I referred to in the 280PAW example above.
I was running approx 370 flywheel on the mixumachi TD05 and my car is under 1200kg too The figures are genuine.

.Thanks Guys.
I think i get the point!
The td05 is bigger and better with the fastest spool up
My G-tech is showing 260atw/ and itīs the same ,when it was testet on a dyno.
isnīt the TD05 much cheaper then the md304.

It's not 'a lot' cheaper, yes it's cheaper but you need your donor turbo which can be Ģ200-300 ish to start off. Probably 2/3rds the price all in I would guess
Unless you DIY

Yes, your probably right Remind me how much they cost again ??
Can they run without a dump valve for added response ??
Skassa
It is the 16G that you're after.

Isnīt the 16g smaller then the one i allready have.
i thought that it was better(free flowing) when itīs bigger
The VF-29 is a 18g isnīt it?
Mike Yes it can but how long??
My vf29 is allready making a bit of noise and itīs just 20000km old.

I went from vf23 to fe modified td05 - to be honest I didn't find the spool point any different between the two, assuming you can remap to suit the turbo.
If anything the 23 was a little quicker to make full boost (but 1 bar in 4th occured for both at around the same point). However, note that I'm running a Maxim manifold.
However, td05 feels (and pulls) much stronger, lol!

My VF30 produced 1.4bar @3200rpm in 4th gear.
But I don't think that it would last to long @+1.4bar tough..
I'm glad I didn't buy my MD304 brad new to..
looking forward to see how the MD304 and VF30 will compare.
