RHDJapan Store Reviews

I've been using this boost controller for a while now. Easy to setup and mount. Interface is easy to use, but does require a lot of trial and error. It's a good buy based on other ebc's in the market. I've had a hallman boost controller where you can set it once and forget about it, but I needed adjustable pressure settings. This fills all the requirements I need.

awesome parts for a awesome price

Very High quality and Perfect fit ... I was Impress by the quality and easy to install ... even if no instruction is provide ... but well if you don't figure it out your not suppose to do it :) Recommend +++

The Greddy SPec LS Kit is a great value for money. You can expect a high-quality product which includes all the required fittings for an excellent price. I would recommend the spec LS to anyone looking for an affordable kit that has everything needed to upgrade.

Not a good review unfortunately, This is listed for cp9a and ct9a versions of the Mitsubishi Evo 4-9

This will mount on to the intake manifold but that is it. The fuel delivery pipe from standard uses a 2 bolt flange, this part requires either an -8 male feed or use the provided adaptor and compression jubilee clip onto the pipe itself. neither is compatible with the standard fuel delivery from factory, adaptions to the fuel delivery pipe from the fuel filter (cp9a) will be required.

The latter is not good enough for 3.5bar+ fuel pressure.
