Thanks for the invite, but my mr2 is in the garage at the moment, with the turbo not quite connected to the engine 
If it's done before then i'll probably head over. Is it still in South Woodham Ferrers?
Ahh thats a bit of a problem then! Hopefully it gets sorted If it's done before then i'll probably head over. Is it still in South Woodham Ferrers?
Indeed it is mate!
Been a while since I updated this. Few things have changed since then.
Had a new exhaust manifold made up and ceramic coated by Zircotec. 1 week to make the manifold, 6 weeks to coat it...
It then went in for a new mid-pipe as that was leaking at the turbo join:
This was pre-mid pipe.
It sounds a WHOLE lot better now but don't have a vid yet.
This weekend I did what's know as the "ram air mod". Basically, the air intake is made of two runs of hose with a resonator in between. I took the long hose, cut it down and attached it directly to the airbox. The result is a lot more noise :-)
There's no dump valve. That's just turbo chatter.
Unfortunately there's still a leak, possibly at the number 4 port. The good new is that all the exhaust work is under lifetime warranty and the people who did it have epic service.
Once it's all sorted for good, I'll get a proper inside/outside vid.
It's still got the crap GM Rochester injectors. I'm planning to replace them and figured it's pretty much the same money to go bigger for future proofing, but that means a bespoke mapping. This is my preference anyway as every change will make some difference to the fuelling and timing requirements that a chip just can't cater for. Matt at DIYautotune.com is looking at the electrical diagram to see if he can create a pin-out for me. If so, I'll be going with an MS3X and will make up an adapter so that the harness won't require any cutting.

I do like these, but am torn between the original shape and the Paul Stevens....
...Your shape has really stood the test of time and still looks like a supercar...
...but there is something about the original that ticks the boxes even though there were so many improvements later.
Either way looks a smashing car

Got a K&N panel on the way for this as well as the bits to disconnect the crankcase re-circ from the airbox. I'm going with the panel as the airbox in this is very well designed with a high pressure cold air feed. I'm pretty sure I could only make things worse by trying to fit a pod.
Hooked up the laptop and monitored what it was doing. Looking at the IAT, I think my charge cooler pump is knackered. The impellor is plastic and they are a 7k mile service item. I've got an electric pump kit on the way with the air filter. So there could be 10-20hp to claw back and no more pump replacements in future. While fitting, I might take the charge cooler out and clean it out. The crankcase re-circ dumps quite a lot of vapour into the intake and I can't imagine that helps the efficiency of the charge cooler.
Exhaust leak appears to be fixed now. They had to drill out some of the threads and tap to M10 with new studs. Included under the warranty for the manifold. Definitely cannot recommend Fast Road Conversions in Kent enough!
All in all, this thing is getting faster and louder... which is nice.

you have encouraged me to want to check my car via laptop, as I have heard the electric pump is the way to go on the charge cooler. . .However as I can just about work a self adhesive stamp can you explain how you do this and what you used. . sorry (I used to sit at the back of class a lot !)
