looking good matt,

the motec moment of fire was a real man celebration!

I love engine start ups

Love the update. I had a similar dash moment yesterday when I was helping to prep a car for someone.........they look shit scary when there are just hundreds of wires everywhere! (labelling took some planning!)

The space from your steering wheel to the indicators doesn't matter Matt; at a cruise it will be easy to remove a hand from the wheel and at warp speed you'll be going so bloody fast no-one will give a monkeys about indicating!

Top project Matt

The engine start was a really nice moment. Very happy as it meant I knew which way I was going ecu wise.

I didn't do any labelling I know the car pretty well now. It only took 20mins to pull the dash out and 30-40 to get it all back in.

I don't really care about the spacing of the wheel as you said its not hard to move your hand and the benefits out weigh that tiny draw back.

Ordered all the motec bits today with Gary and decided on the race tech dash2pro over the motec cdl3. The motec I'm sure is a better unit but as the car is a road car it has draw backs for not having the required lights which the dash2pro has. Both have the same features so hope I have chosen the right one. Been a expensive day lol

Car is down at APT this week having the motec installed so should have a good update in a few days.

Word of wisdom if you fancy changing dash's on a S2000 don't its a pain in the arse. They have wired all sorts through the dash and the dash has different relays built in to control these things. Obviously if its a pure race car it doesn't matter.

Really looking forwards to seeing this finished off with the Motec. Knowing your taste for engineering excellence and Gary's desire to map ECU's properly, the results should be pretty memorable

Even more lively for the snow and ice eh?

That's what I'm hoping for Stuart, I want everything to be as close to perfect as possible(in my eyes anyway) the smallest of issues annoy the hell out of me. When you're next down there sit in it as I think you'll like the driving position. Should be low enough for you now with the Tillett's.

Thanks for the offer Matt

I may have to try it some other time though as I'm not booked at APT for a little while.......keen to try the Tillets though, if only to try to persuade another lad I know to swap over (he's also 6ft plus)

Mapping is done but got valve float so need to sort that out then fine tune the map and more rev's. Going for 9.5k rev limit with upgraded springs and retainers.

Update:

So we sorted the misfire with valve springs and went for a 9.5k rev limit but we believe we went out of the effiency range of the cams so the car used a lot of fuel. So after upgrading to a aeromotive fuel pump I then decided to run a smaller pulley so got 21psi at 9100rpm and the car made 488bhp. I thought I would be happy but.........as I find half the fun in making stuff and playing with the car I have sold the supercharger and going turbo. Either a gt30 or gt35 variant. Looking at other people's power plots the gtx3076r .82a/r starts restricting above 8k so need to make a educated guess as to which one will be ideal, I don't want huge lag just as long as the turbo has 20psi by 5k which even a gt35 should do. I will be making the manifold to suit the turbo and a tial Vband turbine housing as it looks much nicer. So hopefully in a couple of months the car will be up and running. Just got to be careful how much boost I run as at around 2 bar the head will lift with Oem head bolts.

Should also be receiving a vented bonnet tomorrow as I melted a alternator as the engine bay temps got pretty toasty on a hot day. This will also be handy with keeping it all cool with the turbo.

Oh yes

turbo it right up
