Probable bolt in, but things may change on the day. If I can make the complete rear half in one section, and still get it in and out then it will be bolt in. If not, it will be welded in with removable door bars. I know its not the best approach but I think it will evolve on the day.

Picked up the car from Haywood & Scott's today. Sounds great and does the job, not pretty though! I had heard that their exhausts were a work of art, maybe they had someone else do mine. Anyway, got it all back together and been driving around all day.......until the battery went flat.......forgot to check it was charging. Finally sorted that with a second field winding supply and fitted a charge light. I now have charge light, oil pressure light and water temperature gauge and that's it. I'll have to figure out the rest later. The z gauge works perfect with the Toyota temp sender. Still loads of things to sort out/improve but its now back on the road and usable.

The plastic tub didn't really support my back enough so I put a z seat back in.
Couldn't do the cage today as my mate was too busy so it's been put back to next Saturday. So I've spent the day driving and tweaking. I think I need to change the diff ratio as it seams to be reving far too high. Not exactly sure as I've no speedo or rev counter but it sounds high. First gear is pretty useless anyway so I think I need to go down to a 3.7 or maybe 3.54. I thought it would be about right and here's my reasoning:
The soarer had a 4.1 diff and 225/55 x 16 tyres and red line in top was 170mph. The Z's got a 3.9 and 205/55 x 16's. I expected the tyre difference and diff difference to roughly equal out and I'd be left with pretty much the same gearing. Am I missing something?

You are missing the gearbox.
Thought about larger dia tyres?

I hadn't thought about larger diameter tyres but if I stick with 16's I think a higher profile may look odd. Could go 17's but wheel changes are a long way off. As Matt says, I need to find a rev counter that will work off pulses and then use GPS for my speed. It does sound like its reving very high though.....pulls really hard in 5th when boost cuts in though.

Can't really go out in the snow so it's time to start modding. I know I said I wanted an understated factory look with no shiny bit but I need to do something with the rocker covers and ali intake bits so I thought I'd make a start and stripped some bits off the engine on Tuesday night.
I rubbed down the rocker covers and primmed them ready for the paint. Wasn't really sure what to do with all the cast intake bits as the finish is pretty rough so I thought I'd sleep on it. I headed over to Canvey island wednesday morning to get some paint and stopped off at a polishers I knew to see if he could smooth all the intake casting bits so I could get a good paint finish. He no-longer does polishing suggested I he power coats everything instead. Sounded good to me at £80 for the whole lot so I dropped everything off. He rang me back this afternoon and I'm well impressed with the results. Check out the pics below. I'll try and get most of it back together tonight.

Looks nice but the problem is where do you stop? That intake looks a bit corroded.
£80 is the fuel for a trackday
and if you keep the bonnet closed nobody will be any the wiser. 
Joking apart Johnny I'm very impressed with what you have done is such a short time and like I said before I'm interested to see how it goes.
Let Matt have a drive sometime

Yeah, where do you stop and yes the intake does let it down a bit now. I'll have to work out how to strip the intake down. I don't think it will ever stop as I enjoy the challenge of modifying and doing things myself. It may never be the best but it will be all my own work.
We're all different and want different things from our car. Mine is primarily a road car and a project I can tinker with. I will probably take it on the track but that won't be its main role. As i say, each to their own.

Started the cage on Saturday (I'll take some pics later). Spent most of the day getting the main hoop just right. By which time my hangover had reached monumental proportions so I threw my gutts up and went home to bed. Only just feeling human again. Its not that I had a lot to drink but mixing various shot was the icing on the cake. Plus I can't take my drink anymore. Anyway, I'm going to have a play in the garage soon so I'll get some pics then.
Oh no - Turbocharging and shots whatever next? Southerners
