turbo'ing a VTS, options?

  1. #1
    i wanna spend some cash on this vts engine before it goes in the furio, cituning do an entry level turbo kit for £2500 has anyone done a diy kit? any links for whats needed? i make custom stainless steel exhaust systems at work for manifold, downpipe and induction pipework isnt a fuss, any help will be much appreciated (y)
  2. #2
    just my opinion of course.
    A turbo VTS will be animal if done well, but £2500 for an entry level kit seems steep.
  3. #3
    an animal sounds good to me, i would get abit knocked off for trade but not much, even if i knew which turbos were best would be a start

    £2500 is a drop in the ocean for a well built turbo 16v lump

    What, wake up and smell the coffee my friend. I know of people doing the turbo build themselves for around that mark. So for a company to do it, it's pretty good.

    yeah but to be fair its for like 40bhp with no intercooler ect, very basic

    2500 will get you a pretty basic set up.. but you can..with knowledge build a "fair" turbo set up with that budget

    i havent set a budget yet i just wanna do it myself, im gunna start it off with a cheap second hand turbo and go from there

    Jeez, for 2.5k ive got standalone. Quaife, custom shafts, manifolding, turbo.injectors. Refreshed the engine. External w/g and enough cash left for a mapping session

    The search button and Ebay is your friend.and the more research you do.the more money youl save.read read read and read some more.
  11. #11
    talking of turbos does a KKK K26 ring anyones bells for a start-off point?
  12. #12
    Stick to the garrett for starters.cheap and readily available in almost any size you could want. I got 3 gt17s all in perfectly good order for under 200quids.
    A gt25 sold on ebay for like 50quid the other day. Find out what cars they are fitted to from factory and see whos breaking em.

    i can get it for 20pound nd i could make it fit but is it a decent size? + its got a water feed :/
  14. #14
    Ive not seen that particular turbo, but if the 26 is relating to the size then itl be reasonable. For 20quid you cant go wrong. Get it bought. If its no good you aint exactly gonna loose much money.

    but the cituning kit doesnt include them fitting it or does it??


    if you take your time and search the right places, you can get everything you need for 1-1.5k

    very true, i shall (y)

    im sure £2500 doesnt include fitting with citituning
  17. #17
    I built my turbo conversion for arround 800 with refurbished turbo, new intercooler and pipes, used AEM piggyback ecu, new AEM wideband afr controller, used cams, self made manifold. If you search enough, you can find almost everything for good price. Obviously this not include the labor, because i did everything myself.
  18. #18
    ive got the turbo, busy making manifold and downpipe ect but dunno what to do about fuelling :s
  19. #19
    wheres the best place to buy standalone ecu's? and how does a piggyback ecu work?
  20. #20
    Get an Omex 600 off eBay, these are the way forward and everyone seems to be using them at the mo

    whats the advantages of the standalone compared to a piggyback and do you have to uprate the manifold pressure sensor for just the piggyback or both?
  22. #22
    There virtually no advantage of using a piggyback, and 99% of mappers won't touch them as they don't have the software to map them, and the ones that do won't map them to a turbo conversion as they can't adjust the fuelling and ignition enough to make the car run right

    If your after a cheap suitable ecu then just use a predator, they're pretty much the cheapest standalone ecu out there and you can get one for about £350 2nd hand
  23. #23
    i guess the standalone ecu is the better way to go then, id rather pay a little more money and get a better ecu but then again i didnt know there would be much difference between them
  24. #24
    There's a huge difference between a piggyback and a standalone mate

    And I'd defo pay a bit more and go standalone tbh, I'd say the ecu and mapping is the most important part of a turbo build
  25. #25
    Listen to josh mate he's been there and done it, he will point you in the right direction and his advice will get your car done well within your budget :-)

    what ecu would you recommend mate and what about injectors?

    What! Fuck that. If you're dropping Omex money buy AEM or Emerald (or Omex but its not the be-all-and-end-all). But on a budget, predator all the way.
  30. #30
    where can i buy an emerald from? been told of a few people there good.
  31. #31
    A better approach is to find out what your chosen mapper likes the most as you'll have a better result with your mappers preferential ecu - regardless of what type it is. Don't be sold "to" either. If a tuner is trying to sell you something, 99% of the time it's because they are in it for the mark up - regardless if its good or otherwise (not saying its shit, just remember "sales patter". )
  32. #32
    What ecu have you got on yours Ross? I said Omex as that's what I've seen on a few boosted motors of late, re you on about the AEM f/ic? I haven't came across anyone using one of them but at £350 and a leading brand, they can't be bad :-)
  33. #33
    I run Omex as that was what was sold to me. Doing it over, I'd probably go DTA as that's my mappers choice, or AEM for features.

    Constella run an AEM on the 205. It's good. A lot of features for the price.

    Omex is a very good choice for the road though as it has good/fine idle control. I've no negative experiences with others personally just what my mapper has said ref idle control.
  34. #34
    our tuning company is topgear tuning or angel but both dont have rolling roads, does the car have to be on a rolling road to be tuned?

    Depends on budget mate, but a predator would be fine and is affordable, and also plug and play so no pissing about with wiring looms

    As for the injectors for 200bhp use clip 172's, for 270odd bhp (both @ the fly), use megane 225 injectors, anything above use specialist pico injectors unless your raising the fuel pressure

    And to answer the last question yes it does need to be on rollers to be mapped bud
  36. #36
    Sounds good, I've seen Robs 205 in action, goes like a missile, the AEM deffo does justice to that thing lol, he has launch control on it but don't know weather that's tuned into the AEM or he uses an Omex rev limiter launch? Either way works very well for them, il be using a vems, that's what's on the Vts already, but if I was to start from scratch I'd go for the Omex, as there are slot of functionality and a lot of add on's to buy if you get bored lol

    No. Many VERY well respected mappers don't use rolling roads (and even voice their opinions against them).

    I always thought a rolling road was vital for mapping lol, what ways are there around it? Would you have to road map it or can it actually be done stationary?
  39. #39
    It cant be done stationary as you need to encounter engine load vs rpm etc.

    road mapping is very popular - the neighsayers will preach its dangerous etc, but thats a seperate debate.

    Imo, the very BEST maps are developed on the dyno, then "finished off" on the road.

    Andy Forrest is one of the most reknown Subaru mappers. I was introduced to him a few years ago by a friend big into his scoobies. He writes a better explanation than I can.

  40. #40
    Can definitely see what he's saying, but I'd still want to use a dyno for 90% of the mapping session tbh

    Personally I'd only really want to use the road for the very fine tuning of the map...... fuck driving at 100+ mph on the road all day, you'd probably leave the mapping session without a driving license
  41. #41
    Right so if I was to wait to decide what ecu to buy where would I buy a piggyback and 2bar sensor from and what would it cost?
  42. #42
    if your not going crazy on the boost you can use a piggy back no problem

    i had 194bhp out of my old VTR engine with an AX gti ecu and a Dastek, ran perfect for over 10k miles and is now on a turbo AX gti and runs spot on

    lots of people rave about the pred but i have a customer that cant find anyone to map it properly and sort out its issues, the same issues were the reason the car was sold cos the previous owner couldnt get any help with it either

    standalone is bar far better than a piggy back (im now running DTA S60) but unless you want the features of a standalone a piggy back isnt a bad idea
  43. #43
    All I want is my car to run with a turbo at about 200bhp haha, I can't find new piggyback ecu's anywhere or even a 2bar map :/

    Lol that's pretty much my thoughts too. I've only ever had dyno mapping and never had a problem (question is though, would I know? ) My car is always mapped in 5th gear - on the limiter in 5th = 170mph ish now. Fuck doing that on the M1.
  46. #46
    Fuck there's some cheap pro8's there!
  47. #47
    was just thinking the same i payed way more than that for my S60
  48. #48
    One other current issue with the dastek il mention is that the boost modules you need to run boost on them are really rare and very hard to get hold of

    If the op does go with a piggyback ecu then i have one for sale, but with very few people mapping it nowadays, and the fact that theyrd also not very "future mod friendly" I'd just go with a standalone
  49. #49
    the dastek is as future proof as a standalone

    i had mine on an N/A vtr lump then on a boosted one with differnet boost levels then remapped it to engine mods then fittedthe same unit to a different car/engine

    its as mappable as a standalone but admitadly you can control as much with it
    getting the dastek setup was alot cheaper than the DTA

    I'm using AEM F/IC 8, it's piggybak and have built in 3 bar Map sensor, can control fueling, ignition timing, boost, etc... comes with software for map, very easy to use.

    im still no further forward ive just come across another problem, this turbo has an external wastegate, should this put me off or is a screamer pipe a better route?

  53. #53
    yep gt17 saab specials... ive got one of them manis that pop up on ebay every so often from france. they are about 200 quid, infact mine was like 170delivered. reasonably well made and for a couple hundred horses be perfect.

    its also the most compact of the manis ive seen, which is perfect for me, but could be a problem with something bigger fouling the block/bellhousing. but nothing a grinder cant sort

    Could you show me the mani / tell me what to look for dude?
  55. #55


    thats also an off the shelf saab downpipe, just needs a little bit cut out the middle and be spot on, also has a flexi in there too.

    that downpipe was also cheap, and being off the shelf easily replaced.
    btw, its a spare engine....... for mock up purposes only.

    What did you search on ebay? literally saxo GT17 manifold?

    Just a note on that - the bolt pattern is the same but the hole size is different. You'll need to do some kind of port matching if you use a gt17 turbo on a gt25 flange. But it will fit
  61. #61
    Ross, the housing on the 17 of mine is circular. Do you reckon its worth opening the turbo housing up a touch for a better flow?
    The saab mani ive seen was nigh on identical to the french ebay mani. With no smooth transition.

    I can certainly see the advantage of matching the two halfs, although ive personally not seen a 17 been 'ported' and even the cituning kit has a square port. And loads of guys run the 17 on it. I wonder if it will release any so far unseen performance of the 17? Or atleast a better spool up?
    Mainly i went with the 17 as i was initially goi g to run it the other way round, tucked back towards the block. As space in mine is v tight. (16v ph1 106)
    Or have the 17s all so far been ported and noone mentioned it?
  62. #62
    if youre wanting a 16v and going budget.. get a man from a jp4 engine and make and adpator type same as vtr does

    cheap and cheerful.. could have your mani and downpipe done for less then £100 if doing it yoursle.. less then £70 tbh

    Allot of that i wouldnt even use.

    My local likes megasquirt so that would be my choice of ECU.

    Does anyone have pictures of how they done their water feeds? i.e the T's or whatever they've used to take it from, as ill have to make some up, unsure weather to have it all the same sizes.
