scotsman Posted February 7, 2009 Posted February 7, 2009 I've got a UK WRX - with a VF35, Sti injectors, up-pipe, downpipe, uprated fuel pump, etc. With an AndyF remap giving me around 310bhp. However, my VF35 is on the way out (screaming, blades touching I think) so need to get a replacement. Not sure whether I'm best to just get another VF35 for a straight swap - or get a recondition front entry TD05 (cheaper than the VF35 but would need another map tweak from Andy) or go for Andy's hybrid TD04 (and map tweak). The VF35 and TD05 would cost around the same all in and the most expensive option would be the hybrid from Andy - however, I get 12 months guarantee with that - as I'm worried that getting another second hand turbo might lead to it going again in the future. Powerwise I'm not going to be pushing beyond the 300/310 mark and the hybrid goes up to 320 anyway. So - what would you guys do? Cheers Richard.
scotsman Posted February 7, 2009 Author Posted February 7, 2009 (edited) Yep - it's a TD05 16G that I've been offered for a decent price. It's been refurbished recently by Turbo Technics too. More interested in decent pick-up when on the motorway (50-70) - so would the TD05, VF35 or the hybrid TD04 be best? Any views? Cheers Richard. Edited February 7, 2009 by Scotsman
RA Dunk Posted February 7, 2009 Posted February 7, 2009 if your not going beyond 310/300 16G would be perfect, they spool quite well seemingly
~ ~ Cal ~~ Posted February 7, 2009 Posted February 7, 2009 TDO4 Hybrid ! Fastest spool combined with VF35 shove in the back
Big 'D' Posted February 7, 2009 Posted February 7, 2009 Do you know what turbine housing your old VF35 had? My VF35 has a P15 turbine and it is a rapid spooling turbo, it was 2nd hand but I have had no issues with it, if it went I would happily get another one, I am running 325+ bhp with scope for mabe another 20 with bigger injectors. Cheers Iain
frank c Posted February 7, 2009 Posted February 7, 2009 I went from a td04 to the hybrid on my old 99 uk turbo and think it produced roughly 295 bhp. If i was to do it again i'd opt for a different turbo altogether and get more bang for my buck... If you've got a goal in mind regarding power levels etc , go for the smallest turbo available or like Iain , one with a little head room incase of the dreaded power creep
scotsman Posted February 7, 2009 Author Posted February 7, 2009 Not sure what housing my current VF35 has - just a standard Sti one I think. I can't see myself wanting to go beyond my current 310/300 - I drive around a lot on the low map when I'm just heading up and down the road to work - then have the high map for the weekend - so I don't get used to the power and the thrill is still there. Certainly stopped me wanting to up the power over the past 12 months Thanks for the advice and thoughts gents - very much appreciated. Richard.
scoobymark Posted February 8, 2009 Posted February 8, 2009 I had a 16g in my last scoob (wrx) and great early spool and good mid torque 12.9 quarter mile so decent enough
scoobysailor Posted February 8, 2009 Posted February 8, 2009 (edited) I've got an Andy F TD05 16g and the same supporting mods as you (injectors, pump, I/C etc) and I'm well chuffed with it. Early spool up and good power / torque...... Andy managed to squeeze over 330/320 from mine so you will get the power you're after from it. Edited February 8, 2009 by scoobysailor
scotsman Posted February 8, 2009 Author Posted February 8, 2009 I'm getting tempted by the TD05 16G route now - with the remap from Andy. It would probably cost me £100 more than the straight VF35 replacement. Can you tell from the turbo itself if it's front entry (I've been sent some photos) or is it another part which does the conversion? If I go down the TD05 route, I want to make sure it will fit my bugeye Thanks again for all the advice. Richard.

I have a Bugeye as well and the TD05 16g is a simple bolt on (or at least mine was)........no modification required Edited February 8, 2009 by scoobysailor
scotsman Posted February 9, 2009 Author Posted February 9, 2009 I think the TD05 comes as a top entry as standard and it needs modifying to be front entry (since the TD05 was for <MY97 cars) for MY98 onwards.
JohnSt Posted February 9, 2009 Posted February 9, 2009 ...erm, why don't you just ask Andy ? ---john---

emoe Posted February 9, 2009 Posted February 9, 2009 Pre 96 model TD05 were top entry, but very easy to change to front entry. You can either remove the front plenumn yourself, (big circlips) and have the unit machined or buy a replacement front plenumn for about £90 to swap it over. Wouldnt change to TD04 hybrid from a VF35, youll get faster spool but loose grunt. Td04 Hybrid i think is equiv of a VF29.

RA Dunk Posted February 9, 2009 Posted February 9, 2009 just to throw another one into the equation i had a VF28 fitted to the RA at one point which spooled very very well indeed and was good for 320 or so bhp
Big 'D' Posted February 9, 2009 Posted February 9, 2009 I am pretty sure out of the early IHI VF range turbos the VF35 is the fastest spooling within the range, not to make your choice any harder, like I said earlier my one has a p15 turbine housing and has zero lag even paired with a frontmount. Cheers Iain
RS Grant Posted February 9, 2009 Posted February 9, 2009 That IS good figures for a VF28.. I thought they were kinda flow limited to c320bhp. Personally speaking, if I wanted to reach your power levels, it would be between a VF34/35 and a TD05 16g.... can only really see the spool rates being the difference between the two really as they are both capable of decent power. Cheers, Grant
scotsman Posted February 9, 2009 Author Posted February 9, 2009 Thanks Grant (and everyone else). I think I'll go for the TD05 16G since it looks a decent example and get (yet!) another remap from Andy. Sorry to ask again, but does this look like a front entry TD05? Cheers Richard.
