We've just been set up as a new trader on Skyline Owners and I thought I'd write a bit about H-Dev :)

I've been running Horsham Developments for nearly 10 years now - It all started when I bought my first Nissan, an S13 200SX and started to modify it. The company has grown from a 200SX ECU specialist into a fully equipped tuning business, capable of performing any work to your car - from a full service through to an engine rebuild.

We're based near Newbury, in Berkshire, about 3 miles from J13 off the M4. We have use of 2 buildings (totaling over 4000 sq.ft) that are used as an office, workshops and secure car storage.

Here's what we do:
ECU mapping - we can map almost all standard Nissan ECUs and after market ECUs and have our own Dyno Dynamics rolling road:
Parts sales - we sell most brands and keep many popular items in stock for next day delivery
Suspension setup - 4 wheel laser alignment and corner weighting
Servicing - we can service all Nissans with genuine parts
Engine building - anything from road car engines to race engines
Parts fitting
Car preparation (cage installation, track/race preparation etc)

We have an online shop for parts sales and details on the services we offer - updated as often as possible: - currently the Skyline section needs updating but we're working on it.

I enjoy motorsport and compete regularly. My old car was an S13 200SX - it was running an SR20DET that was stoked and bored to 2.3 litre - it produced 605bhp on standard pump fuel and weighed around 1100kg. Heres a couple of vids of the car on the dyno and then at the final Snetterton Time Attack round in 2010:


We now have a 350Z that we've taken from a completely standard car to a road going track car. We will be building a turbo engine for it this year.

You can sign up to our facebook page if you're interested in keeping up with what we're doing.

Heres some pics of a few cars we've worked on:

Jolly F's GTST - we remapped the Link ECU and fixed an issue that was causing a lot of lag - went from 417bhp to 526bhp!

Gary's GTR - we did a lot of work on this car: new turbos, injectors, brakes, suspension etc. The result was a fantasic GTR that went, cornered and stopped superbly

The R35 GTR can suffer from a clicking noise from the front disk - we sorted the problem on Pauls car:
