Had a manual rack in my old mx, much more preferable IMO.

Have you removed the piston/seal in the rack? Welded up the slop in the pinion valve setup?
Mine felt so much better after removing the slop.

De power your current rack and use that otherwise you get a higher lock to lock ratio which is shit for the track.

Not to me its not. Its your money.

My poly bush kit from ebay came with new end link bushes. Unless you can move your steering rack, the bushes are fine. If you want to tighten them up pack a thin strip of Ali under the rack bush so the clamp squashes the bush more.

Not keen on my challenge? Worried a factory engine will absolutely shit on your piece of shit car obviously lol.

Ill race you Lopez, 6 laps of manfeild, your turbo engine vs my stock standard engine. I'd advise not painting it first because I don't want to have to repaint it to get rid of the nasty harlequin paint. The balls in your court.

I swapped all my bushes using a bench vice and a few sockets

From my own testing lag is way over dramatised. I cut 6-800mm out of my evos intercooler piping and had little to no effect on spool time in our datalogs. I then upgraded from a 600x300 75mm thick intercooler to a 100mm model and made more power and spooled faster even with the larger volume. We dro...

The split turbo opens up the way for a non direct drive turbine shaft, gearbox on the turbine shaft, no lag huge top end Why would that be of benefit though? You'd introduce transmission losses and complexity over a simple direct shaft from the turbine to compressor. Im no F1 engineer but in my evo...

I brought my bushes from this guy, heaps cheaper than moss and they have diff bushes which i think were one of the best changes ive made. http://www.ebay.com/itm/PROTHANE-12-2002-MAZDA-MIATA-Total-Suspension-Bushing-Kit-MX5-EUNOS-90-97-Poly-/180911548300?pt=Motors_Car_Truck_Parts_Accessories&fits=Mo...

$25 each from the local Mazda dealer. The bushes are a seperate item, I did a fatcat style setup so didn't need the factory ones.

Nb tophats were cheaper new from Mazda nz than 2nd hand.

There must be more weight to gut out if you wanted. Mine must be around 830-840 with a cage and we aren't allowed to go at the car with a hole saw or anything.

That's a very tall tyre! Would take a lot of work to get it to fit.

Shampoo on the window does the trick

I could do better for free, my face hurts from facepalming

That amount of oil explains why the compression results were so high. How many ml? 30?

I meant how much oil did you put in when you compression tested it? The factory head gaskets go soft I've found, you often can't see where it's tracking like you can on a mls gasket. Check the valves as I suggested, will only take 5 mins. If it had a head gasket leak that was bad enough to drop the ...

How much oil did you put in? If the heads off fill each port with brakekleen with the valves shut, the one it's weeps through more than the rest is leaking.

You can remove any brackets that aren't used and strip the loom back to save weight. Body panels have to be factory. You can add a r package lip and fibreglass headlight vent. Rear spoiler is also free. Your not allowed to bridge panel gaps with tape. Cooling wise my standard radiator is fine in win...

I believe they have been taken down as they are under review. Engine has to be factory from afm to end of the headers. Head shaving is free. Open or viscous lsd, factory diff ratio, 960kg min weight, 15x7 rims, 205/50/15 r888s, there is a specific roll cage design, any single adjustable shocks, fact...

Was a good first round, i managed 2nd overall with a 2nd, 7th and 4th. Racing is very tight, 1 missed gear and you loose 3 places as i found out
The handicap races involved a fair bit of panel damage for some!

The toe will be out, you have to run more camber than a mx5 is capable of to get excessive camber wear

Or dobis or kings which are available locally. My fronts are 180mm long with ample clearance. 200mm wouldn't be an issue.
I do run nb top hats which will make a difference.
