Very true...

I used to buy all the SC'd 5's I saw but now PH etc have been extolling their virtues they fetch more as cars than as parts.

1.8 kits are particularly rare.

Would it be possible to fit a 1.6 SC kit to a 1.8 using the SC mounting bracket MOD that MrFast is working on.

I thought 1.6 kits were rare? I only say this as I have a 1.6 which I'm (of course) thinking of supercharging. You could PM me details of the 1.6 kits and I wouldn't at all complain.

IME there are perhaps 5 to ten times the number of 1.6 kits out there compared to 1.8 kits. That's in terms of numbers sold, rather than types of kit.

Unfortunately I don't have any kits ATM.

Apologies for the thread resurrection...Depending on funds I may have a Chimaera before I set off with a bunch of PH'ers to the Alps in September, but if I'm just short money wise by the time I hit September I may just supercharge my '5 & take that!

Any update on any kits available for a 1.6? biggrin

Hi,
Have a look on nutz at the M45 build thread & maybe have a go a putting it together yourself (if you are competant with a spanner & welder). If not, Mr fast on there is currently putting together kits.

How difficult was it to fabricate all the bits and actually fit it to the car?

Considering this myself, and don't want to start the project only to think aaaaahhhh I'm out of my depth...

1.6 Engine that's done over 200,000 k. What else would need doing to it above and beyond the s/c kit?

Just make sure it's up to it i.e. give it a full service, replace any hoses that have gone hard, replace thermostat & rad cap, make sure cooling system is clear & working well. High mileage really isn't a problem as long as it's been looked after.

Make sure it's not using any/too much oil, maybe a compression test as well to make sure it's not completely worn out?

OK, I'd probably go with a new rad and samco hose kit just to be sure then. Cheers.

I've heard of cars in the states where they got boosted after 200k miles and then did another 100k+ without a problem! Of course US miles are generally different to ours as there is less stop/go driving and more open roads but even still, that's impressive!

For interest, here's how I did it a couple of years ago.
Bought a M45 installation off a car that was being sold, drove the car with it on to check all ok before buying the charger.
Came back grinning.
Anyway it was a standard system with powercard for fuelling.

Fitted it myself, as it's not too difficult. Had to buy the ABS kit to get the bits that make the intake fit around the ABS box on the firewall.
Over time I bought other bits to improve it, that's basically replaced the powercard with EMB.
Bought a J&S Safeguard? knock sensor for safety.
Took the EMB, EMB harness, J&S to a place by Gatwick airport, cannot remember the name at the moment, had these bits fitted and RR tuned conservetivly as I now have 170+k on the clock.

Now 189.6 BHP 156 torques.

Costs, as far as I can remember them.
Used M45 with powercard £1,100 (Recouped £60 selling the powercard on)
ABS kit £110 (Moss)
EMB £200 (Off Nutz)
EMB Harness £110 (P5)
Knocksense £175 (Nutz or ebay)
Fitting EMB/J&S/RR tuning £350
So for just over £1,200 I had a working charger, over time I bought the other bits and stored them until I was ready to go, a further £700 or £800 spent over a period of time.
I have the performance I want, it's not the fastest but has the performance the 5 should have had from new! I can with this system upgrade it to higher BHP, but that will require injectors, charge cooling etc., I feel the bang for buck is not value for the additional HP over the 189 I currently have.

Downsides.
The charger was sold as having around 24k on it, which is difficult to check. I now think the bearings are going (Sometimes I get squeal when I bury the pedal) so I'm looking to have the charger rebuilt, this should be less than £200.

Resurrection time.

Looking at a 1990 S/C MX5.

I've read both positive and negative things about the Jackson Racing kit. Not after massive power. It's going to be a starter racing car so want to keep things slow and steady.

JRSC is fine as long as you make sure the belt is correctly aligned.
Have you checked the front of the engine to see if it has the light-weight crank?
