Never heard anything about them, might be worth checking on TRO as it's more commonly used on EP3's.

If you're wanting something a bit cheaper than the go to manifolds (Tegiwa, Dc sports, Etc...) Have a look at the Funky Power manifold, I read somewhere it's a copy of the DC Sports mani'.

User 'JasonDC5' bought one and said good things about the quality, Have a gander at his thread.

I had a Japspeed on my EP3. Only real issue is it clipped the rear engine / gearbox mount every now and then. I had the exhaust hangers adjusted slightly to push it clear. Nothing special.

Build quality was good. I'll dig out some pictures if you like.

Good power gains ?

Didn't actually get dyno done with it. Felt much better in mid range, much more willing to rev out too.

Seat of pants dyno said it felt good

Skip to 2:16. Video of me testing the video overlay on TorquePro. Gauge readings are well off, so ignore those.

Most commonly used on the EP3 as they are cheaper option than the Toda or the DC Sports


Look on CTRO for a review on them, I think they are ok for the price.

Thanks for the help the other one I have seen is eight speed ? Again not herd a lot about them ? Any one got one

Good for its price.. only problem people usually get is the flexi blowing but apparently if you upgrade your engine mounts, it'll reduce the chances of that

 

[FireDance]

When fitting a DC Sports they suggest uprating the mounts, or at least fitting the inserts.

You will find that most are a copy of something. Tegiwa is a copy of the Toda.

Thanks looks like I'll get this, I know its hard to know but power you think this would make on OEM ecu at a guess peak ? 0 to 5 lol or more like 5 to 10 ?

Literally no idea mate, but it did feel 'free-er' on the EP3. Get the 90 degree elbow rather than the straight like in my pics, I remember it bring very tight with the straight spacer.
