I gave 3500 danish kroner for mine used a couple of years ago, think thats about 400£.
Havent seen it against dc2 airbox , but pretty sure Mugen would Come above it. Probably not by as much as the ek4 ☺
Mugen air box is best, back to back against my ek4 stock box i saw 8hp and 12nm gain on same dyno
Cant find dynosheets thou ☺
Spec was b16a2 stock with toda v1 header, 2.5" Greddy catback and No cat ☺
With stock air box 176hp, 155nm
With Mugen air box 184hp, 167nm.
Both was untuned stock ek4...
Skunk2 ultra street and 68-70mm TB if u have good breathing/exhaust mods already works perfect and gives good gains over stock ITR tb/mani

Here in Danmark the record in a na 1.8 is 265hp so 250hp is realistic ☺ officourse i different on dynos how high/low they read. Nice build keep it going
Regards Carsten
Just drive slow and No wot and monitor afr then i Cant se what should be wrong driving it to ur tuner ☺
When u drive normally ur o2 sensor is controlling the afr at around 14.7:1 or so called lambda 1 ☺
Well my b16a2 with ek9 cams/valve train b18c6 tb/intake manifold made peak power at 8500 real rpm, if i was running stock ecu i would never have got the rpms it takes to reach max power
and Yes offcourse u need a good exhaust/intake setup to make the best power/torque from the setup:)
