well i thought id post a little bit of a build as i need some help software wise and I'm coming to a bit of a wall,
i have a mk5 gti axe which is currently stage 2+
i have bought a precision 6162 turbo which is something in-between a gt30 and gt35
an 034 motorsport cast manifold
rs4 injectors
tial 38mm mvs wastegate
my aim is to hit 400 for now ( please no k04 comments)
I'm having all stainless boost pipes made this week plumbing my intercooler in and i have a spare tsi engine so i can build the rest of the pipe work, downpipe and dump tube off the engine. and hit the build in a weekend or so.
now here is the problem I'm facing... software.
there is unitroninc - requires me to send my ecu to canada for flashing
revo - designed for gt3071 they ant sure if the software will work with turbo as its a bit larger...
r tech - they want too big a specialist for what I'm aiming for...
eurodyne maestro suite - this is the best i have found and price point is very good but i may get stung for import duties but i have stand alone capabilities and ease of flashing plus datalogging
so really what I'm asking is do people know of any other software out there for the bt conversions?!
ill put up some pretty pics if people are interested...

Sounds good. Thinking of going down this route in the future so be good to see how it all goes.

cast manifold arrived today but not taken pics yet, injectors and billet wastage adapter should arrive soon :)
-
What internals you gone for?
-
I'm staying stock till I have a nice working setup then I shall go forged.... I have aimed for 400 but at 20psi on a gt35 with unitronic does inbetween 350 and 400 so what ever it comes out at should be fine on stock
-
Ah ok, some time to save up the pennies for a nice setup. Should be a beast when done.
-
In fact there are some ie rods on here for £350 but I have no use for the Pistons so it's a bit over priced for me also I don't know what the stock Pistons will take on their own...
-
Yer it all soon adds up very quickly.
-
That it's true so far the cupboard under the stairs has about 600bhp in it haha but the smile it puts on your face is more then worth it!

Just a few more pics, Iv had my cooler mounted but not yet plumbed in

And here is my turbo mounted on the cast manifold

I have a Precision 5558 on my GTI with Cupra BWJ engine, and i'm making 489bhp. What made you decide on a bigger turbo for just 400bhp?
Also are you sure it'll fit? Have you bought the specific CTS silicone hose from intake to turbo?
I have REVO stage 4 software combined with an Eboost2 (GFB makes a boostcontroller that works fine with REVO as well) and it works great.
I think you'll have issues fitting the turbo due to the size. My mechanic at BNA Performance DK had to disassemble the turbo to get it in place with the engine in the car. Remember Norlock washers for manifold, wastegate and downpipe or it will losen itself.

Original plan was to build a r32 turbo I had pretty much the full kit just needed a do our car but that's where I struggled as I wanted it to drop in but it was turning out a huge job and cost me a fortune where as I wouldn't have to spend much more to just build my Gti
So the turbo was to run on a vr6 hence size and it was too good an offer to refuse tbh.... 400 is just to start when it's run in and I have a working set up I'll go forged and go for 500/600
I know it's pointless being fwd but sod it.... If needs must I'll put it in a s3 at a much later date
Fitting it is going to be an issue... I'm having custom boost pipes and down pipe made so if I have to we will do pie cuts to get it to miss the shafts... Iv seen gt35's on a Gti so I don't see it being a huge issue...
Quick question what's the best bhp you can get out of stock Pistons?! I know the rods are the first to go....
-
Also software has been sorted pag parts in the states will send me a custom tune in a ecu so it's plug and play :)
-
Today's offering... Rs4 injectors

You should get the CTS custom silicone hose if it fits your precision as it will make your job much easier. Regarding room for the turbo, you have chosen a more compact cast manifold than my CTS one so you might have a bit more room, but going higher bhp it will be less than optimal for you.
The level of bhp isn't an issue, mine are fine from third and up, boost in second it just spins the wheels no matter what tyres i chose.

I'm staying stock till I have a nice working setup then I shall go forged.... I have aimed for 400 but at 20psi on a gt35 with unitronic does inbetween 350 and 400 so what ever it comes out at should be fine on stock
You might be better off with an ED30 lump (BYD) or S3 as it has bigger wrist pins, 4 bolt mains and stronger rods / pistons than the AXX. 20 psi from a GT35 shoves a hell of a lot more air in than 20 psi of K03. Pressure is one thing, but pressure with a lot more flow is another. Think 20psi garden hose vs 20psi fire truck hose. One makes you wet, the other knocks you off your feet.
Not knocking your build, just putting that out there :)
Nowt wrong with high hp FWD either, I had a Corrado VR6 turbo which was insanely fast and good fun.
Standard management can handle it by the way. Not many affordable standalones support direct injection, let alone variable fuel pump control etc etc.
-
No I appreciate the post!!
The psi is just what the unitronic site says I'm unsure what psi I'll be running but I can use an ebc to adjust to suit
As for the ed30 engine I have a k1 engine lying around will the bottom end of that match up with an axx head?!
I have found some con rod drawings online and it turns out they are made from en24t steel which we have at work so I'm debating making my self a set!
-
Ah OK! 350-400 seems a bit weak from a GT35 @ 20psi tbh, should be nearer the 500 mark! It's a whopper of a blower for a 2.0 and it will haul arse when it kicks in :happy2:
Not sure tbh, don't see why not, but the reason I suggested the whole ED30 lump is because it's head is a bit different to AXX as well. A stronger alloy apparently.
Yeah why not! It'd only be some chap in China making them otherwise ;)
-
It is rather low for the size of the turbo I assume there isn't enough flow to really get going...
It's the tsi/FSI thing that I'm stuggling with weather it'd match up but I'm trying to avoid swapping the engine to be truly honest...
Well that's my thought, if I can make aircraft parts I can make a set of rods! Haha
-
Saves some money to for other upgrades. I dont really see the point of swapping the engine if your gonna uprate the internals tbh. If staying stock then yes in swap.
-
Tbh I'm surprised at the respone to me making my own rods to be very negative and Itl be too hard haha
It'd be worth swapping the head that's for sure! All the gains are to be made with a better flowing head, wonder if it can be adapted... Got a spare head so be worth finding out!!
-
Shouldnt be to difficult as long as you got the equipment and comfidence then go for it.
could play around with porting and polishing it.
-
Yeah got all the equipment to do it its a fairly simple job so we shall see how it goes... If I can find titanium cheap enough I'll go f1 style haha
-
Titanium rods. Now that im liking the sound of lol.
-
First price I found was $2k for the material alone :signLOL:
-
F*** that. ill pass on the titanium idea when it come to it lol.
-
I'll try and find a better price, aluminium rods are a possibility but you have to take a lot into account but the rewards are worth it.... An extra engine on stand by is a must tho haha
Finally got my stuff bolted together and found a very cheap Eurodyne software on the bay so I'm tempted to buy that early!
I'll post a pic in a min

Oooh looking nice. Making me want one more and more now :signLOL:
