Yes, that mat is crazy!

Way to steal my pictures without any credit.

In the original post I had them listed as not my pictures but I didn't want people to misconstrue the rest of them as not mine. But thank you for them. I took some of my own but they came out really badly. Your pictures do illustrate just how crappy the factory swirl pot is.

I just didn't want people to think your builder was able to get the whole pot out intact (which without knowing it's from a different car that had the tank cut open and rewelded together, might be misleading).

We also put a lot of work into it and were one of the first to identify what the problem with the OEM swirl pot was.

The pictures are obviously completely different from mine in both quality and size. I googled S2000 swirl pot and those pics came up, just the same as the SOS kit results are from the SOS website.

From the pictures of my tank, it's clear my fabricator did not cut open the tank but instead used the fuel sending unit hole to somehow get a tiny cutoff wheel in there and rip it out.

Updates! The 8374 is no more. Have a 9174 now. Should hopefully hit 600hp at some absurdly low manifold pressure and not really affect my spool much.

Take a look at this civic at 18 psi. K24 with low compression and the .92AR IWG housing;

N/m the first quesiton.. I see they sell a magnet kit which makes sense..

So the installer was able to remove the stock/oem swirl pot via chopping it up with a dremel through the fuel pump opening? It looks like a project but should be doable..

Steven622

Correct. He didn't have to cut that tank open at all.

hi steven, the EFR9174 is proving to be a very good turbo - slotted right between the EFR8374 and 9180. in precision talk the 9174 would be "6766" - it uses the 74mm/66mm turbine wheel from EFR8374 with the larger 91mm/67mm compressor wheel from EFR9180. This turbo was originally considered the big brother to 6758 (similarly aggressive wheel match) when we tested it on the SSE evo years ago. The 9180 makes a bit more top end power and the 80mm turbine wheel has lower backpressure to be certain, but will spool slightly later. I really dont think you need a quickspool valve on an s2000, as it would lose the benefits of twinscroll and the introduce a possible failure point, but im interested to see how you do with it.

ot, but here is a plot from my friend's 2.1L evo9 with EFR9174 at 42psi, small runner AC kit / 3" downpipe:

Heya Geoff,

Some things I saw about that car that you forgot to mention: it's running 12.5:1 CR! Why is the boost threshold so high? I posted on the EFR thread on EvoM as well. I can only postulate that this is the 1.45 housing just adding more RPM for the actual boost threshold.

As for the QSV, I think you'll be pretty surprised. I've seen them in action in person, and quite frankly before I originally went with the insanity of my Subaru build, I just wanted to have a 9180 lowmounted with a QSV. The only thing they really do is swap 4-500rpm off the boost threshold in exchange for a couple of % off the top end, which is why I went with a 9174 vs the 8374. The 9174 flows more than what my block could handle so I'm not really too worried about not being able to hit my power goals with pretty low manifold pressure.


Lastly, you think you could hook me up with a BW integrated QSV turbine housing?
