Quest S2000

Hello,
Over the last month I've been building my engine, and soon it will be finished. I'm using an ECUMaster ECU, however I'm not sure where to take it in the UK to have it mapped once it's complete. Does anyone know of a tuner familiar with both S2000s and ECUMaster software? Cheers.
Here's a few photos of the build process:

Parts selection for the bottom end - Block machined by clockwise motion (87.25mm Bore), Brian Crower 97mm Billet crankshaft, ZRP Lightweight F22c rods, Mahle motorsport stroker pistons, and ACL Race bearings

Bottom end assembled, bearing clearances all measured within spec.

With the added stroke and the piston crown volume, CR will be high, in the 13:1 range!
With this combination of rod and piston, the reciprocating weight is a good bit lower than oem, down to 912 grams for each assembled rod and piston.


Head assembled - Ferrea valve guides installed by DY engines, Brian Crower valves, Toda Valve springs, F22C Honda valve retainers.

Also, I'll be using Toda Spec C2 Cams, with the exhaust rocker arms machined to suit them.

So, that's the build so far. If anyone has any advice or feedback, I'd be happy to hear it, and if anyone knows of any tuners experienced with both S2000s and ECUmaster software, please let me know. Thanks!

Maybe add location

Sounds similar to the build mine's currently undergoing. Toda high comp 2.2 kit (12.5:1). Clockwise doing the machining, his neighbour (Dan at HPE Automotive) doing the build. Cams, springs & headwork from Clockwise too.

I use a great guy for tuning, but not sure if he does that ECU. I use Motorsport Electronics.

You say piston/rod now at 912g, what did the oe set weigh in at, just out of interest.

I know MacMotorsport in Dundee are very familiar with ECUmaster but doubt that's local for you! The owner previously had a 2JZ powered S2000 as well.

Looks like a nice build.

Good point noodels, Ideally near bristol but no issue if its a couple hours away.

Nice, yeah! I think I remember reading about yours in another thread. Who do you use for tuning? I Might contact them and ask if they've used ECUMaster before

Quest S2000

Thanks! While that would be great, Dundee is a little bit far haha

Hmm, I still have all the original parts, although I haven't weighed them. However, I looked on another thread, and someone else had weighed theirs at about 1100g. So, the new parts are a good bit lighter!

Alex Hickson - find him on Facebook. He's based north of Chippenham/Marlborough if I remember correctly. But I met him at MTech Dyno. He's done loads in the MX-5 community, but he tuned my S2000 nicely.
