Right finally decided on what I want from the car now.

I want a turbo that'll get me 0-60 the quickest.
My aim has been 330, but to be honest if i can get the 0-60 right down.

My car will only be for road, maybe some track.

So question is what turbo?

I have changed my mine from the td0518g to 16g and now i'm looking at the td04 hybrid.

Any advice is greatly appreciated.

vf35 is another option as very quick spooling,but maybe the td04 hybrid would be a be a bit better 0-60? maybe someone else will confirm.

ITs a tough one, I do have the VF35 on mine at mo, but its fudged, so think i will be going for a td instead, at least they are rebuildable.

Must admit though, although my VF35 is fudged when it comes in it comes in with some force.

a mint vf35 can be had alot cheaper and they are a good reliable turbo,mines a genuine 37k vf35 and its excellent with plenty more to come from it,im running 300bhp with very little mods at moment.i paid £280 on here so its a great option if on a very limited budget like i always am

From fastest spooling;-

1) TD04 Hybrid
2) TD04L
3) VF35 (deliberately ignoring the more aged, fragile VF20-series and hard to come by VF30)

At least with the VF35, you have scope for upto 340-350... AS WELL!

Running it DVless with a bunged recirc port on the tutbo intake pipe, will also keep the inlet tract primed with the air charge for even quicker throttle response! Don't worry, the VF30-series are okay to run DVless (younger/less mileage, so less fragile than VF22-29 ones)

You need to run boost from the startline, launch control of some sort is your best option. You need to sit on the line on boost.

Then your limiting factor will be grip or gear ratios, can you hit 60 in 2nd gear? changing to 3rd loses lots of time.

I can hit 60 in second, so thats all good. Mine is a uk so longer gearing. Isn't it all about torque to get you to 60 quicker? I just want a really quick road car. I'm keeping standard ecu so can't get launch control.

MartynJ

Everyone seems to be missing the point here, Andy Forrest carried out the fastest 0-60 I have ever heard of from a Subaru with a huge GT42R based hybrid. If you want a fast 0-60 you need power at the top end of the rev range, not torque at the bottom.
A VF34/35 or 18g equipped car will be faster over the 0-60 as it has a better spread of power further up the revs.
The TD04 hybrid (Which I love on a daily driver) is better at 50-70 in 5th for instance, better low down response making it better in gear than through the gears.

sorry for the thread hijack...........but i will have a VF35 available at the end of feb with 42k on it and running 100%.....£300

Now i'm getting confused in which one to get. The car is a daily driver. And might do the odd track but very rarely. I'm i right in thinking the 34 is ball bearing?

Getting a fantastic 0-60 is more about a perfect launch than which turbo. Your transmission and clutch won't forgive you for long if you repeatedly try violent launches.

Andy

vf34 has quicker spool than vf35 due to its bearing setup

MartynJ

Yes the VF34 is a ball bearing unit, very reliable and with the right bits can make some very good figures from a stock engine.

I have done a 0-60 of 5.3 with just 240bhp using a G metre on the TD04, doing 2 launchers in each direction and it's done STINKS

iTrader: (39)

yea it is,the vf35 uses divided thrust bearing but im lead to believe there isnt a great difference between the 2.the vf34 is quite rare to buy secondhand and will still cost alot,where as the 35 can be had at a good price as mentioned above,if my funds were not as restricted i would have probably opted for the 34.

what would the 0 to 60 be on a 93 wrx with 330 bhp with the tdo5 16g

Best advice I can give you, to do it on the cheap is to get the TD05 18G back on, assuming it is a genuine turbo and work from there but if you really want spectacular times get yourself a 500 bhp plus turbo and invest in a few spare gearboxes. Now once you have got the turbo decison made get yourself a Simtek with Anti Lag and Launch Control. You now have the means of coming off the line with boost at predetermined revs that can be adjusted to suit conditions and your style and you will miantain boost on gear change. Once you have got that sorted out you need to look at wheels and tyres which have to be sufficient diameter to get you comfortably over the line at 100 kph in second and grippy enough and wide enough to get you off the line quickly.
With your 18G you need to spend a lot of time getting your setup right to make the best use of the power available.
If you are serious about this you can also start lightening the car, junk the spare wheel jack, only one tow eye front and back, throw away the prop catch plate and various other bits of junk that only add weight. If you get really serious look at the weight of your wheels and check out what is available at much lower weight.

Give me the wieght of your car with you in it, is that 330 at the flywheel??
and i can give you some calculated performance figures

how much does a wrx weigh iv got rid of ac and got light weight kei wheels lol and im 15 stone and no fat boy jokes lol. not sure it be running rough that it got hdi gt 2 fmic,full decat,walbro,550 injectors,hks filter,with simtec so would that be fly wheel or to the wheels lol

deff not at the wheels then, so slim how much do you and your car weigh. Only doing calculated figures so this is based on 1300kg of lard and 330 bhp will give you a 0-60 of low 4's. Soz dude had to get the slim jokes in as you ask nice for them. I'm just under 15 stone mi sen but no fatboy here.


joz got it.

Virtually all documented bhp figures in the UK are at the flywheel i.e. the higher figure (helps manufacturers flog vehicles, obviously...)

Right joz can you do this one for me, looking at a second car and need to no 0-60 on a merc E320 cdi with mods I.E remap taking power to 275bhp

dint no the weight of the car with the bits missing i got 4.03 low 4's

Only count that as a ballpark guide, as obviously gear ratios/FD, turbo delivery, tyre compound, traction/grip, etc aren't accounted for.
