turbo kit, what do I need to know?

[Noisy]

I'm looking into turboing the mx5, I have seen a second-hand Greddy kit locally for £900, which includes a intercooler, there is the option on a emanage and larger injectors as well.

Just wondering what I need to know about these kits and if they are any good? The turbo is a TD04.

I'm running the turbo and manifold at 15psi with no problems

[Noisy]

what sort of power do you make at that level?

The last Greddy kits I saw were £850 NEW so yours (with and IC) still seems steep.

They are pretty crappy kits where lots of std stuff needs upgrading but they can make good power.

Also includes a Bipes unit as well if that makes much difference, out of interest what do you think such a kit should be worth then?

Greddy kit £500
Bipes £100
IC kit £150 upwards depending what it is.

If you can get the turbo, intercooler, emanage and injectors for £1000 that would be a good deal and would be good for 200bhp ~ 10psi

- 2nd hand greddy turbo's tend to go for £500-£550
- Intercooler with pipes and silicone hoses will set you back £200+
- Emanage blue tend to fetch circa £200 or less
- Supra or 1.8 injectors are less than £100 for a set of 4

No point shelling out for the bipes and an AFPR when you've got the option of the Emanage.

A 200bhp MX5 is very fast and you'll love it. I'm at 15psi ~ 250bhp and it is scary fast.

Thread reanimation - what sort of damage does this sort of thing do to the fuel economy? I'm giving some serious consideration to FI-ing and fettling instead of upgrading out of the MX5 to something M-powered or some Blackpool plastic fantastic...

Depends what you use to control the fuelling. When my car had a JR Powercard I'd get about 25mpg at the very best. Now I have an emanage I regularly get 28mpg during normal driving. I expect that to improve again when I upgrade to Adaptronic.

Turbos tend to be more economical than superchargers. I'm not sure why but my guess is because it's easy to avoid boost with a turbo due to the lag (however small that lag might be it's still there) whereas with a sc the boost is there as soon as you give it a touch too much throttle. It's being in boost where the fuelling solutions add extra fuel that the economy suffers.

[redgriff500]

Turbos are simply more efficient than SC's.

No belt for starters, less rotating weight and arguably are powered by waste gases etc

(Arguably as they obviously restrict the exhaust)

I'm going over today to have a look over the car it's currently fitted too, being local helps and also piece of mind that I can see the car running before buying helps too.
