My bellett - What should i do with it

[Waldo]

im currently started my complete rebuild of my bellett. but am unsure on which path to take with the motor, its currently g200w turbocharged with a haltech f3, but im thinking i have to rebuild the motor and spend alot of money on it to makeit go fast and slap on a set of brand new 45mm webers, i look at the car as it is it only makes 145rwhp turbocharged, and think it would sound much nicer with webers on it with 130mm trumpets. but the good thing is that the engine is fuel injected and its probably pretty rare being turbocharged and all. But being turbo just doesnt suit the style and era of the car, and lets face it webers do sound great. just give me your thoughts on what i should do to the engine....To keep turbo or not to turbo??

Im for fitting webbers. Webbers dont melt pistons.

Yeah man I'm with Oz. The turbo is a novelty, but those carbies sucking down juice at full throttle would just be cool.

My GT has an EFI DOHC and I'm thinking of carby-fying that too, or at least something along those lines.

[Waldo]

i could probably go a injection perfection style quad throttle body setup and keep it fuel injected still would sound nice with the trumpets and quads

I have to say there is nothing like the sound of carbies... just such a unique noise and definitely an era setup.

That being said if you want to sell the turbo/manifold and swap parts i've got a N/A g200w that i'm looking at turboing It's in an '84 gemini so it's a bit more era... kinda... not really. Would suit me anyway

Keep us posted on your mods.

Cheers,

If it was mine, i'd stick with the EFI setup. I love how reliable my efi g200w is, how it starts straight away every time (even though a good carbie will do that too) and how it has torque from the moment its running, even in cold weather, how it goes hard and still chews hardly any fuel... but I dont really expect anyone else with a love of 60s cars to agree with me

Keep the turbo? thats a hard one. Im sitting on the fence having trouble trying to figure out if I should add a turbo. The car is fast enough to be a lot of fun without it and I suspect a turbo might be too much. Pitty your not in the Adelaide area, i'd trade a ride in yours for a ride in mine and it might help both of us make up our minds!

A turbo G200W should be above 300HP - if not 390 (as with the GT sold last year).
NA G200Ws with the HDT tuning are ~230HP.

You'd be pretty spot on with those figures. In the under 2 litres sports sedans a Gemini with a G200w and weber style injection manifolds puts down 245 bhp at the back wheels and that is naturally aspirated. He also runs it with an early Wolf-3D the same as mine.
A couple of years ago when I was scrutineering the beast. He informed me that he had picked up inlet and exhaust billet cams new for $10.00 each. I felt like crying as they would be like rocking horse poo to find.

well my g200w is turbocharged runs 10psi has had some mild porting running old school haltech, has very dodgy intercooler and pipe work and only made 145hp at the wheels, i thnk if it was to push 300hp it would break very quickly. i wouldnt like to try that. hence why i have taken the turbo off and rebuilding motor to NA speco with some sweet trumpets, as turbochargers just sound poo when your driving around

[IZU069]

The 145HP sounds reasonable - st'd G200W is 135HP (flywheel); add 40% for turbo (190HP) and deduct 25% for transmission.
But the 230HP (flywheel) N/A engine is reliable. Excluding the forged pistons ("needed above 180HP"), it's not far off standard (port & mildish cams).
Mine was merely 100kW (wheels) but >300Nm above 2k, though it was a standard import 117 G200W to which I added 2xDCOE45s and a $200 exhaust. Since I didn't want to pay ~$1,500 for forgies, I left it at that.

I would have thought the 390HP turbo was unreliable, but apparently not. However it was built by an accomplished former Bellett-Gem NSW member.
