So did you guys fit the 37.5 or 58 restrictor? I read Yorkie was worried about the size (presumably of the 37.5?)

Also, if you haven't removed AC, did you protect the pipes or is this overkill?

I've got the 58 in which is the same size as the inlet so effectively no restrictor. Not touched the a/c pipes

I think the smaller restrictor is to be used if you aren't upgrading the fueling.

You don't need to use any of the restrictors in the UK cars - just make sure the injectors and fuel pump are up to the job along with a decent map

They are mainly part of the "PnP" options for the USDM models IIRC + along with the HKS Flash editor (not suitable for UK cars).

So why does the HKS fuelling kit include a 44 restrictor? This is in between the no fuelling upgrade option and USDM size???

Unless I'm reading the instructions incorrectly.

Don't you need one for the mounting?

So as the US have different options they need the smaller one?

We can use the 58 with proper fuel system upgrade and a good map?

That's how I read it anyway

CynicG

That's what I thought, the restrictor is also a mount, so using the 58 is straight through.

58 is straight through

Any updates Yorkie?

No not really. Haven't had chance to do much more. Inter cooler outlet pipes then the actual kit will be on. Just injectors, fuel pump, wideband, decat and ecu to fit after that. Sounds a lot but reality should be 3 or 4 hrs tops. Fuel pump is a bit awkward but I've done it a few times now.

First snag I've come across the oem fan won't fit with a bigger alloy rad and the intercoolerpipes at the moment. Need to see if I can trim some bits or if it's going to need an alternative solution
