They can be quite Rapid, Lyndon at Rogue thought mine felt an easy equal to a 300bhp MR2 after he mapped it.
It produced 250bhp/220lbs at that point and weighed 960kg PWR of 260bhp/ton.
Its since had Ryan remap it on 99ron, a bigger turbo cover 3" inlet up from 2.5" and a fair bit more weight stripped out.
If I ever go down the forged internals route
(mines still on standard un-opened long block, 133bhp stock) my current fueling/ turbo setup would do me a happy 320bhp, if the car now weighs 940kg and had 320bhp you'd be looking at 340bhp/ton
There are several turbo kits, most basic being Greddy
& HKS and then the big boy American kits by Bell Engineering
(Corky Bell's company) and Flyin Miata, these go right up to GT35 territory.
My cars got a Bell Engineering kit on it with a GT2860RS.
A friend has a smaller turbo, GT2550 with the same kit and his mate has an EVO VIII FQ300 and he can happily sit on the EVOs bumper.
