Hey guys,

i heard that g200s bolt straight into gems, and i was wondering if anyone had any experience with them and if they are ( non turbo) a powerful engine for the gemini.

Thanks. thumbsup.gif



P.S. how much do do the g200s usually go for? dunno.gif

Very strong engine, make very strong power and the conversion to EFI is the hardest part. One of the better engines for a nice street Gem

Go to ozgemini.com for bucket loads of info on these motors.

Just to clarify, the G200z is the single cam carb version that shares the same basic architecture as the standard motor. The G200w (that iamhappy is referring to) is the twin cam EFI engine based on a different block design, gearbox etc.

The 'w' is fairly rare and some bits can be hard to find for it. While the 'w' has moar power in stock form, they cost more and are more work to get running in the car.
If you are on a budget it's probably better to stick to the single cam g200z; the money you save on the 'z' over the 'w' can be spent on upgrading the carby, cam, exhaust etc.
With the single cam there's also more scope for converting to turbo later on if thats teh way you decide to go. (can also convert the single cam to EFI using rodeo inlet manifold etc.)

Complete running g200z's usually go for between 300 and 600. Complete running g200w's (if you can find one) usually go for around 1k of thereabouts pending condition. I've seen some stupidly priced twin cams too...

i heard g200s were illegal in gems, but ppl seem to not care cause they are hardly noticed from the stock engine

no they're not illegal, im not sure what capacity is illegal, but im pretty sure its around 3000cc, but the max you can turbo/supercharge is 2300cc... i know of a few G200's in gemini's and they cut sick!!

They are legal, they are EFI so emissions is no problem. The engine capacity is within weight limits.

Its a newer engine that the original engine, there should not be any problem.

If you want to make a donut machine bore it out 60 thou that's the limit and make sure you have everything really clean and do the head bolts up exactly how they tell you to .use a well prepared 1600 head I had twin 40 mm side draft Webber's on I swap them for a single 45 mm side draft it was a lot better more power and quicker revs get the dizzy regraft a good set of extractors . I could sit on the spot in second gear with 225x55x15 on the back all day .if you want it to handle like a go kart get 2 rear sets of v8 vk commodore springs and put them in ... Awesome little car then .. good luck
