Differences people? I need images. Would like to know as I'm pretty sure I have as twinscroll sump on mine and am currently looking into converting my uk to twinscroll

 

there is a twinsroll sump on ebay at the mo, with pics http://www.ebay.co.uk/itm/3212526733...84.m1423.l2649

 

Twinscroll conversions are not that simple. I suggest you look into all the extra bits you will need.

UK what?

If your sump bung faces passenger wheel its twinscroll sump, if it faces driverside wheel its std uk 2.0 sump

 

Already checked it out. Sent a cdb to engine tuner for a 2.1 stroker. Then when it was built took my car for fitting. I was at the time running an ej257 in my 2005 sti. They swapped all the parts from the 2.5 to the 2.1, this included I believe the twin scroll sump, dip stick and pick up pipe. If that's the case then I may only be looking at equal length manifold, uppipe, turbo and downpipe.

 

I thought the 2.5 and twinscroll sumps were the same? Or very similar?

 

They are the same

 

That's also what I am led to believe, which is why I'm looking into it in so,e depth. I understand that converting a uk to twinscroll would not see all the benefits of a true jdm, as they run different cams I think. But still maybe worth looking at

 

Craig, they are definitely the same sump.

 

twin scroll is the only way to fly....simples

 

So if I have the 2.5 sump (twinscroll) then I'm looking at equal length headers, uppipe, turbo and downpipe?

 

I have a good up pipe here, and I also have a set of manifolds that have seen better days lol but can be repaired if interested from a Jdm blob.

I also have a mint set of twin scroll manifolds and uppipe from a Jdm hatch but runs a different flange to the vf37 if any good to you
