  • Turbo Upgrades - what have you done:?

    I'm thinking there's been plenty of water under the bridge over turbo upgrades for the colt, specifically the stock TF035-10T turbo. Plenty of people bang on about how good/crap it is and why anyone would bother with upgrading to a TD04L-13T either by complete substitution or machining out the stock TF035 to suit the TD04L internals.
    There's been some development with turbos and tuning on various Colts, I know of at least 4 Colts in Adelaide who don't frequent (i.e.: Post on) the FB pages, nor do they put stuff up here, I can see why too...

    Currently am going down the path of doing just I mentioned, putting the TD04 guts into a TF035 frame. Other than a pass or two down the strip to benchmark things, my car is unlikely to ever be raced so I think upgrading the stock turbo a bit is pretty much the next step prior to a full forge build.
    Cost wise it's going to be about $1k when you factor in cost of finding a stock TF035 (If you don't want to your car off the road), sourcing a half decent TD04L-13T CHRA, finding a reliable place to do the work and some 440cc injectors plus $1100 for a custom dyno tune.
    I'm expecting in the region of 150kW ATW give or take, minus the normal variables associated with the Coriolis effect and other "My tuner/dyno/builder is better than yours" type discussions. It'll be dyno'd before and after to compare the delta.

    My main desired outcome is the overall change (aka: 'The Delta') over the current level of tune in my car (currently about 135kW ATW) and the drivability of the thing.
    My car's driven everyday with mostly commuting duties and some 90klm/hr cruising along a fwy. Every now & then it'll be taken for a fang through the hills around here, some traffic light drags (Nothing crazy - think fwy/hwy on ramp type thing) and some rev limiter stuff 'cause I like the sound of it.
    I'm not looking to spend $1000's on fancy gear when I'm unlikely to ever need or want to use it. I've spent plenty of time and $$$ racing pushbikes, motorbikes, carts & cars and I'm over the associated effort - plus I've got a family...

    From my somewhat limited research, the BW EFR range of turbos are pretty much 'The Shizzle' given unit cost and what you can get out of them. Witness our Colt forum resident knob-jockey ;-) and his current chariot pumping out the best part of 290kW+ ATW. The thing is simply a rocket but I'm sure he'll no doubt tell you it's not the easiest thing to live with on a daily basis, even on semi-daily basis. Never the less, it's a pretty good yardstick on how reliable these cars actually are. He runs the stock gearbox and driveshafts (I think?) with obvious upgrades to the engine (Power related), chassis, clutch, wheels/tyres and suspension but otherwise it remarkably stock. There's a couple of guys over in WA who also have some pretty quick Colts but again, they're still fairly stock with pretty good levels of reliability. You could run the EFR6258 on a stock (unforged) motor but there's not much point really, IMO it's overkill unless you forge it, 3" zorst, fancy clutch, etc, etc.

    Currently I've been in discussion with a local turbo specialist who turned out to essentially be not interested in doing it so I've moved to another place recommended to me by my tyre guys. They used to run a pro drift team around Oz and these guys built their stuff for them. I also have a tuner lined up who is very big in the tuning game and has been around a very long time and well versed in the OEM ECU.

    So, my plan:
    TD04L-13T CHRA fitted into the TF035-10T frame
    440cc injectors

    Fairly simple, what're other peeps doing?

      Either no-one is on here anymore or someone encouraging people to keep their cards close to their chest.
      I'm going to bet there's an eastern states retailer who's about to come up with something very similar to what I'm doing so they want to keep it quiet. What happened to the 'Open source' group minded thing that used to be the Colt scene here in Oz...

        My plan is just to get the tf035-15t hybrid on. Maybe port the exhaust housing a bit more as i've found a photo of a more extreme version so that encourages me to grind away a bit more. After that, or before that, e85. Progress is slow as I'm spending a lot of time doing XML and tunes (and real life has habit of taking over rcolt time).

          Turbo is ready!

          Been bit of an ordeal to get it modified but I now have a TF035 modified with TD04-13T internals. Will be a straight bolt-in for the OEM item with manifold, dump, oil and coolant lines all retained. Was supposed to pick it up Friday but when they went to replace a damaged stud they stuffed and I had to be somewhere else before they could replace it.

          Also in the market now for some Denso 565cc 'Blues' to tune it up. The guys modding the turbo only sell Sonic brand injectors which was going to require some more work to fit and after the way they carried on with the turbo modifying I wasn't keen on going through with it when the Denso 565's are 'plug & play'.

          Plan is to instal the turbo and tootle around at waste gate pressure (1 bar) making sure everything is working OK until it gets tuned properly.
