can you show me where you got the info on the vf43 prone to cracking??

quoted from another thread by duncan

VF48 or VF43

Both are 370bhp turbos and very responsive. Neither suffer from surge unlike the VF35 which is a surge fest on some cars.

Wanted more response with a smaller turbo. Still debating, but will decide very soon

Wiley

 

Willey best turbo for your will be VF34 or VF30,these turbos are great WRX.


Jura

 

Ran a TD05 20g in mine which is 330bhp and it was so laggy it was only in there a day!

 

Wow was there any reason it was only 330? Should be getting nearly 400 on a 20g. I wouldnt be wanting lag with 330. Theres much better spooling turbos around for that sort of power

 

Yeah i had a vf35 on mine as standard as i just took it off and sold it, i hird the 48's crack but hadnt hird anything abotu the 43 other than it is very similar to the 48, i wanting a vf model turbo really, just see a 43 for sale and thought that would be a good upgrade and was seeing if it would run at 400 bhp of if i would have to get a td model

 

A vf43 wont do 400bhp I am afraid although it may get close to that on a race fuel or 20% meth mix.

Both the vf43 and the vf48 crack exhaust housings.

 

Sorry i meant it was that before, not sure what it ran with the 20g on it, it wasnt on there long enough to find out! The turbs didnt kick in till 5000rpm which was useless to me although when it did hit it really hit hard! My engine just didnt have the power to spool it up quick enough The VF35 seems ok so far though

 

5000rpm?!

 

About 4,200rpm a 20g should be properly boosting.

Maybe 4,000 with a harvy OEM ported uppipe/headers (and asumming a decat d/p?)...

 

Uk 2000 car by any chance that this 20G was fitted to?

 

Am gonna bump this thread and see if theres anymore opinions lol I wanna change my TD04on my bug and im looking for the best cheapest replacment I think a VF34/35 is there much difference? if i can get 300 with supporting mods il be happy, im not a big number chaser............yet lol

 

VF35 is cheapest option out there which with supported mods will do 320-350bhp.

VF34 is great turbo and best suited for WRX with VF35/VF30.

VF34 is ball bearing turbo and spool fast almost like TD04,VF35 spool slower than VF34,but both are great turbo,on my WRX has made VF34 350bhp.


Jura

 

Thanks for that Jura I was hoping you would reply lol will I notice the difference between 34 and 35 spool time vs power, I mean in real life not numbers on a graph lol

 

In real life VF34 is hard to beat by VF35,i've run mine and this turbo has been just amazing.

VF35 have slower spool,not massive,but have slower spool against VF34.VF30 will be again good option,but on VF35 problem is boost creep,if you are will go route of VF35 i would port wastegate...


Jura

 

VF34 it is then, might as well pay the extra and get best( for what I want) CHEERS Jura your a diamond

 

No my shell is Uk but engine etc is import

I wish i hadnt sold the 20g now as just fitted a 2.5 hawkeye lump in it and the VF35 is a bit small so may sell it and get another 20g

 

Hi Kirstie

on 2.5 will be nice too VF43,VF48 or as you suggest 20G.


Jura

 

Cheers Jura Well took the Scoob out last night and had no boost whatsoever, after a check it seems my turbo has siezed? So will be getting a bigger one quicker than expected, oh the joys!

 

GUTTED! ah well if you needed a reason now you have one

 

One question for anyone in the know...is the classic td05 the same as newage? iv been offered one but dont know if it will fit?
cheers lee

 

The OEM TD05H is a 16g and it was only fitted as std to the early "phase 1" MY93-96 era cars.

To that end, then yes, it uses the std OEM single scroll flanges etc. So it will fit any EJ turbo engine sporting OEM pattern single scroll headers/uppipe, etc.


EDIT: But the OEM 16g's comp cover is top entry, so the 'snorkel' would need to be cut off to accept New Age cars' front entry turbo intake set-up. Or a proper front entry comp cover can be bought and fitted (from the likes of Andy Forrest).

 

If its converted to front entry,yes will fit and these turbos usually do 320-330bhp,great turbo for WRX

On classic is usually 90 degree TD05,IIRC


Jura

 

Cheers lads prob more trouble than its worth then lol iv been thinking though its probably not got too much life left in it! Im trying to rush a bit nice1 for info tho but im gonna wait for vf34......Im putting my foot down ha

 

I will have a vf 35 for sale on Monday once it has been removed and inspected. It has only covered 42k at astandard boost and will let it go for £250.

 

sorry to hijack the thread, but just wanted to know if a td05 20g would still laggy on 2.5engine?

 

A 20g would work great on a 2.5! I reckon it'd spool at c.3,500rpm or thereabouts! (It'd be like a VF34 on a 2.0L.)

 

Will keep my eye out for this

 

The 20G is a very good turbo on a 2.5 and can be very cost effective. This assumes a 2.5 with standard internals. Properly mapped, no lag and very responsive. 1 bar of boost before 3000 rpm and a nice car to drive. If the 2.5 has uprated internals I would be going for a bigger turbo.

 

What supporting mods? Thanks in advance.
