lets talk turbo`s
 

right guys i am currently running a jdm wrx 1995 with a fmic, 440`s , 255, td05 16g, fpr, simtek, maff delete ect ect, the car is running 336.2/335 on v power but seems rather lazy and laggy as it doent really spool up quick enough tbh,, i know the vf series turbo`s are a much quicker spooling turbo but which one do i need?? i do not want to be going much over 340bhp at the minute as i have not done the gearbox yet so whats your advice and if somone has somthing suitable please give me a shout,.

VF34 without doubt mate would suit thoses needs perfectly :thumb:

is the vf34 not a roller bearing assembly, would this reduce spooling time and when do they start to spool and max bhp,..
steve,.

The 34 is a roller bearing where as the td05 is a sleeve so isn't as good a spooler as the 34.
1 bar is a round 3300-3500 depending on spec and 3700 would see full boost of 1.4-1.5 depending what you want to run boost wise.
The 34 is hands down a better turbo than the td05 not that the td05 is a bad one mind.

Surely a VF35 would fit the bill too :thumb:

+1 but the 34 is a better choice due to roller bearing design but still the 35 is a good route as well.

whats the spooling times on both mentioned as the vf35 seems a much cheaper option,.

35 is around 3-400 later than the 34 given its a sleeve design like the td series

I'd imagine you'd see as much as 500rpm between a 34 and a 35 (in the 34's favour). On dyno it may be different but on road i'd say about right. Of course, it could always be a bit of a smaller or larger gap but not by much :)

Having said that, i'm sure you could purchase a VF35 a bit cheaper

Edit to say Wiley is currently selling a VF34 :)

ahh thats the sleave one then ,lol thought it was the 34 that was a sleaved one,. plenty of 35`s going for the £160 mark but cant find any 34`s , is the one on here worth £400

the spool difference should be minimual and you have the hassle of fitting a front entry turbo to a top entry turbo as standard engine ie. the inlet manifold is in the way etc.

Whats spool like at the moment?

5,500rpm i get peak torque,. isnt my td05 a front entry

There like rocking horse sh!t mate so demand dictate's the price and £400-£450 is the going rate yes.

peak torque 5500rpm? you sure? thats very late.

header leak?

no it will be top entry like all standard td05 16g

just looked , top entry lol

no header leaks at all, i have had them sealed and checked and re checked, there is a header leak now as my antilag has killed my up pipe but on the dyno no leaks at all,

got a copy of the graph? seem very laggy

how much of a job is it to fit a front entry and do you reckon the tdo5 could be on its last legs with the slow spool,.

just uploading one

Not to hard to fit,just need a 90' bend silicone pipe to make up for the lack of the normal snorkel on a tdo5 mate

what he said, but need to make sure the silicone elbow cannot collapse.. as the turbo will suck it shut.

here you go http://i1226.photobucket.com/albums/...1-23202925.jpg

another option is vf48 which i run on my type r.
very good turbo with smooth power delivery.:)

Good power but v laggy.

Something a miss

I get 1 Bat at 2800 RPM on my TD05-16G, Only after I have removed the manual boost control. Could be the control of the boost sol.

everything is spot on ie boost ect,, could it be a compression(rings) issue or impeller damage as everything else is ok,.

I dont think you will notice a great deal of difference in spool from the td05 to the vf35. Cant comment on the 34 as have never used one. I went from a 35 to a td05/18. Spool is 200rpm different. Yours is spooling very late. As Simon say i think theres something else not quite right.

mine makes 1 bar at 3250.
i dont think that is laggy.

got a vf34 for sale

£400 posted

wiley

agree thats not, but OP graph appears laggy.. laggier than normal for a td05, seeing as this is his main annoyance / reason for changing the turbo it might be cheaper/easier for him to fix the spool issue on the current turbo :)
