VF35
 

How much does a VF35 usually go for second hand? Looking to upgrade my TD04 in my UK Turbo.

Hi Chris

I sold mine for £300.00 (came from a sti8 17k miles)
Seen them go for slightly higher on ebay although I'd persoanlly prefer to buy from someone on here.
Second hand traders/ breakers sell them for £450-500 (last one I saw was here Jap Performance Parts)

Average I'd say is between £300 - £350

HTH

APi will sell you one at a competitive price mate. I've got one on mine as part of an APi upgrade pack and my UK MY99 now produces 319bhp and 316ft lbs torque. V good turbo; not significantly more lag than the Td04 with asignificantly bigger and longer punch. You will, of course, need your car remapped to suit though.

I think mine was around £250 IIRC, off ebay. It came from Israel.

iirc API do recon VF35's for £350..;)

Just gone from mapped TD04 to a VF35 with usual mods on my 05 WRX. As NS04 say's lag is a little more noticable (pedal needs more movement) but after a week or two you don't notice it. What you do notice is the increased SHOVE. The difference between 276x266 and 348x333 is incredible, but then again my car did respond very well according to Bob..:D

what other mods did that include, Jason?

I am hoping for similar figures to those jasonius!
My MY03 WRX is booked into Tracktive next week:-
VF34, 500 injectors, headers (ceramic coated), another remap by Richard Bulmar. I am hoping for an easy 340/340 really. Or nearly there, but i wont be happy with 300 or 320, LOLOL.
I dunno, figures, its only numbers but it matter to me! :)

Forgot to ask, jasonius, is the difference in power/torque that good? Ace!

EDIT again:- Forgot to say, i am having an AP clutch and lightened flywheel done too.

How does the VF35 differ from the VF30 & VF34?

VF35, sleeve bearing turbo, has a smaller exhaust housing P15, runs out of steam 330-340 HP, VF34 is a roller bearing turbo, bigger exhaust housing P18, spools slower than a VF35 but offers more top end power than the VF35, seen upto 370 on Dyno Dynamics rolling road but this was at silly boost levels and it was surging all over the place, 350-360 would be a better proposition on sensible boost levels.

VF35 (ported)
Ported headers
2.5" s/s exhaust
Sti pink inj
Walbro 255
Green panel
STI TMIC (scoop & undertray)
NGK PRF7b's
Motul 300v 10w40
Bit of porting of intake TB etc

Also;
T25 suspension setup
OZ super L 18's & TR-1 225/40's
Pagid 421's and goodridge hose with Motul fluid
Although brakes are better than standard I think some AP's are needed at this level..:D

Think that's about it..:)

The car is MUCH stronger (even though I initially missed the response of the mapped TD04) and now pulls harder for longer. Can say that I wouldn't want it any quicker for the road..!

Hi Mate,

Glad to hear your mapping session went so well; that's a fantastic result!! A bigger blower certainly makes a nice difference doesn't it? :D

Ns04

Bloody hell i cannae wait till Friday now then! LOL
I hope it is dry though, mind you, in a straight line that donr matter! :D

I'm in kent and would need the turbo, fuel pump and reg fitted. Then ofcourse i'll need a remap on my tek2'd ecu. Who's the best down south??

Speak to Sussex Performance centre in Crawley.

In the South for ECUTEK or alternative new age mapping I'd stick to the regulars;

Bob Rawle - BRD Developments
Paul @ ZEN Performance
Mocom Racing

NewScoob, how much loss of responsiveness did you notice yourself ? What model of Scoob do you have and what turbo did it have as standard
- a TD04? What mods does your Scoob have ?
What other mod's would I need if I was swapping to a VF35 on a mapped 01 WRX, with centre pipe decat ? (currently 273 bhp courtesy of Andy F).

Nice spec Jason. How's the gearbox? ;) I'm tempted to get some Pinks for mine now you wicked chap! :D

F

Andy,

See here mate (have a cup of tea handy) :lol1:

In short. It's a bigger turbo, so the boost threshold (the point it kicks in) is a bit higher in the rev range than the TD04 (about 500rpm I'd say) but in terms of lag (the delay in reponse to the throttle), there is very little in it; the VF 35 spools very quicky, as I understand it, this is due to the small exhaust housing. Incidentally, a set of ported and wrapped headers go some way to negating the slightly later spool up and help liberate more power, so they would always be on my list when upgrading the turbo!!

The fact that the turbo kicks in later has to be put in context if you look at the following graph, you'll see that at about 2900 rpm, my car is producing about the same torque as a std UK turbo at it's peak (5500 rpm IIRC). My car now produces its peak torque at 4500rpm. Similar story with BHP, my car now produces as much at about 3800 rpm as a std turbo at about 5500rpm and from there, of course, it just keeps getting better!! This makes for a very quick road car, especially when you take into acccount torque and power to weight ratios.

lol, I'm hoping that later newage 5sp is stronger :idea: (there seems to be a few 03> running ~400, andy f + neilo) and that my silky smooth driving style :D will prevail..! Saying this I've missed more shifts than ever recently..:eek:

Floyd and NS04, have you ever timed your 60-100 times running the VF35..?

Here's my lardy (1350kg) newage:

YouTube - ktj 60-100 oct06

Sounds nice NS04 :)
I am taking mine in the morning for its work.
Think i will copy you and put a post up all about it when i have driven it.

I haven't mate, but if it's any indication, here is the estimated figures quoted by the performance calculator on LetsTorqueBHP - Home Figures: 319bhp, 1235 kgs

60 - 100 (Secs) 6.46

I'm not sure if that was taken driving through the speeds or from a start at a stable 60.

The same estimate for your car, assuming 348bhp at flywheel and 1350KGs weight


60 - 100 (Secs) : 6.24

So yours is marginally quicker over that increment :thumb:



Madass, all the best for tomorrow. Enjoy the bigger shove!! :D :thumb:

Jason

Power at Flywheel (BHP) : 333
Weight without Driver (KG) : 1250
Power to Weight Ratio (BHP Per Ton) : 270.68
0 - 60 (Secs) : 3.87
0 - 100 (Secs) : 10.10
60 - 100 (Secs) : 6.23
Quarter Mile (Secs) : 12.54
Terminal Speed (MPH) : 111.39
Drag Strip Quarter Mile (Secs) : 12.14
Drag Strip Terminal Speed (MPH) : 115.15

I'll try to RR the TD05 before I go VF37 to see what that does but I think it'll be quite different.

F

OK, that's it, you're both a few tenths quicker than me!! :brickwall :cry: ;) :D

A FMIC and another visit to Bob should sort you pesky new ages out!!! ;) :D :D

ns04

BTW I drive a classic if you didn't know.

F

F it would be interesting to see the TD05 plot to compare against both VF's..;)

:confused: should i fit (if possible) my spec'C' turbo onto mrs spec'C's classic when i upgrade???

I didn't realise there was a spec C Classic. I thought the designations were

Turbo 2000
WRX
WRX STi
WRX STi Type R
WRX STi Type RA
...
Oh, hang on, wasn't there 'V limited' editions too?

If it already has a VF28 or something like that on it though, and it's in good oeder, then I'd be inclined to leave it be.

What year did the spec c get a twin scroll turbo?

If it is a twin scroll it's not a direct fit to a classic. Will need headers and up-pipe too (possibly downpipe?).

Likewise if you're not going twin scroll on your new turbo same would apply.

NS04 - try reading spec'c'57 's post 5 or 6 times slowly and all will become clear ;) :D

BTW I doubt anyone with a VF35 turbo would be worth while switching to larger than 440cc injectors (if you already have that big), at very most a little increase in fuel pressure should see them max out a shade after the turbo ;)

Dave

Lol WHOOPS!! :lol1: Must read things more carefully next time!! :D

Ns04

:lol: sorry guys should have made it clearer..... ;)
