  2. Turbo mapping advice

    in Engine Tuning

    Posted

    So currently in the process of building a low boost cheap turbo vr6.

    Current is to be:

    Holset hx35

    Tial 38mm

    Bosch red injectors

    Stock clutch hopefully

    De comp plate

    Drc 268 cams

     

    In terms of mapping I can go to vince at stealth for a live map or a united Motorsport chip. I believe distributed through the phirm

     

    1st question : any ideas on vince a prices for mapping a turbo build ?

    2: would the united chip be ok for what I need . ( not drag racing it or track days . Simply for a show car and to have a bit of fun )

    Vince charges £350+VAT and is one of the best in the business.

     

    UM/C2 etc will work but will have much larger tuning tolerances as it's a one size fits all sort of thing. Similar Price to Stealths tunes but Vince @ Steath will be able to dial it in to a much better tune.

     

    I have a C2 Stage 2 chip atm but once its back on the road it'll be going to Stealth and the C2 chip will be moved on. The C2 chip served its purpose for testing and ironing out hardware issues last year.

     

    Hope that helps?

     

  3. turbo thoughts - am i right?

    Thanks for all the great advice. I have been looking around and I think I want to run a stage 2 c2 chip so I need a turbo (holset hx 35 is a good shout as seem to fetch £200 s/h) and eBay cast manifold. Genuine Bosch 440cc (which are really expensive!) And a 4inch maf. The link I posted before I read you can use just the housing and my genuine Bosch sensor in it. And then get on the hunt for turbosmart or dial wastegate but most likely A/V and a good quality recirculation valve and decompression plate. 

    I will probably make a short intake to keep costs down too. 

     

    I think I have a plan so can start buying.

    I may have a C2 Stage 2 Chip coming for sale soon :)

    I'll stick my 2p in as ive just finished my build.
     

    First of all, Nothing wrong with Ebay turbo's so long as they are sent away before installation for a 360 degree thrust bearing upgrade and new seals. This is what stealth do on their kits. You want to be looking for one around the 0.82 A/R mark for street use.

     

    Injectors, DO NOT get the cheap ones on ebay/amazon. I had 6 delivered, 2 stuck fully open, 2 didnt fire at all and 1 fired intermittently and only 1 fired as normal. Ended up hydrolocking the engine at idle with fuel. Drained 10L of fuel from the sump. Emerald sell genuine Bosch 440cc injectors suitable for a VR6 at around £60-65 each.

     

    Wastegate wise, i am guilty of using a cheap wastegate but that's due to be changed very soon. Heard bad things about them but im about to change the spring so i'll inspect it then. I'd go tial or turbosmart as previously mentioned.

     

    Install ARP head and rod bolts when you do the spacer. Use a mk4 gasket, seperate the 3 layers and use copper spray to seal the two outside parts either side of the spacer IIRC.

     

    MAF use a 4" housing and a genuine bosch Maf sensor. Dont use anything else if you plan on going for a 440cc chip or remap.

     

    You'll need upwards of £3k to do this well. Anything under that expect problems.

  8. eBay Chinese turbos

    in Engine Tuning

    Posted · Edited by Drewsus

    I have an ebay GT35 copy and upon stealths recommendations i sent it away to TDI turbos to be rebuilt before fitting for 360 degree bearings and uprated oil seals. Been great for 3000 HARD miles so far in my mk2 vrt. Turbo was £140. Rebuild was £220. Bargain in my eyes.

    Can I ask why don't you build your  own kit it's not difficult !

    then you can choose your own turbo , management ect ect

     

    Some people aren't mechanically minded or may have limitations like lack of tools/space etc.

     

    I'm lucky in that aspect as I'm eager to learn and have the space. I found it incredibly fun doing it myself. It really challenged me at times however I thoroughly enjoyed it.

    4" MAF Housing. OBD2. Can come with or without sensor. £80 Without sensor. £100 with. + Delivery.

    Vwpartsinternational Stage 2 Turbo tuned ECU with Immob Defeat and socketed. Tuned for 440cc injectors at 3bar. Absolutely spot on, and only selling due to getting something else at a steal of a price. Only had it 6 weeks, still has 6 weeks worth of free revisions with them if required. Equivalent to C2 stage 3 so can be run up to 400bhp with the right set up. These are £400+ new from VWParts, I want £250+Delivery. Can show it running on a car if required.

  23. VR6 Turbo - which one?

    in Engine Tuning

    Posted · Edited by Drewsus

    T3 0.82AR - Precision are far more expensive than a 35 if you get the dbb versions. Cheaper one I always suggest a Kinugawa or Mamba although this will only save you a few hundred. Holset is also another cheap alternative. 

    Perfect thankyou. 

     

    Would you have a link to any of those please?

     

    I have been eyeing up this one.

  24. VR6 Turbo - which one?

    in Engine Tuning

    Posted · Edited by Drewsus

    Apologies if this has been covered many times. I have just purchased 'DJiceman's mk2 turbo project and I believe the turbo has failed. From the information he has given me, my understanding is that it is a chinese turbo.

     

    I have seen that the Garrett GT35R turbo's are popular, however I'm unsure of what specs of turbine housing and compressor housing I need as there are multiple options. Ideally I'd like someone if possible to tell me what specific turbo to buy, (specs and model)

     

    Are there any cheaper alternatives available that still yield similar build quality to that of the Garrett? I've seen the Precision 6176 which is more what i'd like to spend if possible. There are a range of choice when it comes to the specification though. " Exhaust housing inlet, Exhaust housing A/R, Exhaust housing Outlet and compressor housing" This is what i'm struggling with.

     

     

    Apologies once again, I've been trying to get my head into the research but I'm still relatively new to this.

     

    Many thanks, Drew.
