vf22,vf34 or td05 18g
So ive currently go a vf22, im buying an apexi power fc to go wth my other supporting mods. Im wanting around the 350 - 370 bhp mark, and am just wondering if anyone can advise me on which turbo to use... The vf22 dosent seem to spool too slow and pulls hard on full boost, only being standard sti 4 boost that is..
I want the quickest spool up as possible, hence the reason im trying to decide which turbo to go for.
Thanks

I've heard that TDO4's spool up quicker. VF34 out of them, don't think there as good as the 18g top end but spool up early in comparison.
He's got a V4 STI freshly rebuilt engine.
All a waste though cos we all know black cars are slowest

You dont want lag, so I'd say dont go for the TD05 18g as they are laggy, not as much as the 20g, but if you want near zero lag go for the VF34. Its a roller barring turbo so does spoll that bit quicker... I've just blown my turbo on MY99 STi and I've just bought a VF34 Altho I wanted it more for the fact I'm gettin anti lag in a couple weeks and the roller barring design will survive it longer than other turbos.
If you really do want zero lag, go for a twin scroll VF37! You will need the appropriate down pipe and up pipe as the fitments are different, but you can pick up the turbo, and up and down pipe from japperformanceparts right now for £1000 all in
If you want a VF34 I can put you intouch with a guy thats got one in near new condition right now for £525 or ceramic coated for £600

Let's just say that the engine failure rate on none new age sti's running over 350bhp is quite high due to the rods breaking (they are not exactly great), so no not recommended unless you have spare cash floating around for a rebuild, but you do get one or two that run more without issues, but the vast majority will fail
As for the 18g, go vf34 or vf35, or even the 16g, all are less laggy

Tony,
More questions lol!!
My Type R spec is semi forged- i.e Eagle forged rods, ACL bearings & V9 x drilled nitrided crank. The pistons are standrd though. If I went for an 18g around 350-360 bhp would this be too much for standard pistons?
Cheers.

Pistons would be ok for that its the standard rods that suck and you have replaced those but I would personally go for the VF34 over the 18G as its less laggy.

I have a rebuilt engine by ZEN with forged STi 3/4 pistons and Hawkeye STi rods. Paul at Zen said he'd be happy for it to run up to 400bhp.
So your pistons should be okay... BUT... as TB says, the rods could be the weak link??? Not sure how strong STi 4 rods are? Anyone?
Also, the VF35/34 route are pretty much good for only 350bhp. I'd go for the 18g if you want to get 350-370. Or possibly the HS380?

I think I'm set on the 18g, hopefully its not too laggy although the close ratios in the type r box should help with this.
Rods are eagle forged ones so should cope.
Std Top mount and std 440 injectors able to cope with over 350/360?
Apologies I just realised this whole threads been kinda hijacked to some degree!!

The rods in the classics are the same across the board on the 2ltr turbocharged engines, so the rods in a uk turbo are the same as those in an STI, stupid but true

Also 440cc injectors will surely be squeezed right out(?) - I'd get some 550cc or greater...

Air charge temperatures - i.e. the heat of the boosted charge of air going into the engine (after having gone though the IC core).
If ACTs are too high - like what can happen on the small, and less than ideally positioned TMICs - then they could promote detonation...

Tony Burns, Hi, my car is a 05 wrx ppp but now with decat exhaust inc. uppipe and remapped by Bob rawle (301 bhp) is the vf34 plus 550 injectors the best way for around 330 -340 bhp?

Thanks for all the replies, im looking more towards the 34 now then, so why is it that no ones mentioned any of the vf22 onwards turbos... I know they aint as reliable as the 30 onwards but surely they not too bad. Im probably gonna go for 350 ish, dont really wanna push it. Just yet
