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.

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
