I'd much rather see a SMG or DSG gearbox in mine than some weird engine..
As for the engine, I'd just like to stick a compressor on and that's about it
Also a quaife diff would be nice along with the extra power

DSG gearbox, in a sports car? Tsk.

[Black Knight]

Why not? It shifts faster... And you can shift with paddles on the wheel.. and you can never miss a shift, or make the gearbox suffer or whatever.. bugatti veyron has it ))))

Would a boxer engine fit? How big's a Scooby lump, or a Porker's!!

[Jim_Cross]

Yes it shifts quicker, but it goes against the pure sportscar ethos. There's no skill in it, and you lose that joy of nailing a great shift. Yes DSG shifts quicker, but it also feels like an auto - there's no noticeable gap between gears. Don't you just love that feeling of redlining in 2nd, slotting up to 3rd and getting that kick again as you plant the throttle? None of that with DSG. I'd much rather have SMG II, which is slower, but at least it feels more like a real gearbox.

It's all about the skill of driving well, getting that perfect downshift with a nice HT blip - if you're going to fit DSG, you might as well have traction control, stability control, reverse parking sensors, active wotsits...

[Black Knight]

You have some valid points there..BUT My view: not having to break your legs(and kill your gearbox if you're not good at it) trying to HT downshit lets you concentrate better on steering and braking the car etc.. It is not really comparable to traction control and stability control.. not to mention DSG like gearboxes actually shift FASTER which means better lap times than without it. While stability control usually causes worse lap times.. Also, although I like changing gears on a manual, I must admit I love the idea of seamless/endless acceleration. If you ask me, I'd most rather have one of those variable transmissions like in scooters and a few cars(audi a2?).. It keeps the engine at the same revs where you get most torque to the wheels ultimately giving you the max torque at all speeds, seamless and endless acceleration and getting the maximum out of the engine and the car without revving it too hard at any time... I am a driving enthusiast, but I'm not a pistonhead. While I love internal combustion engines as without them there'd be no cars we have today, the need for gear changing - a transmission is a direct result of internal combustion engines nature.. If we had different powerplants in our cars(e.g. electric powered) we might never have invented gearboxes.. but cars would still be cars with four wheels, racing would still be racing..just no gear changing.. would that make everyone who races a noskill newb? I'd love a powerfull electric engine in the speedy.. It would last long, no problems, no oil, no water.. it's very light and simple.. no gearbox, no clutch. it works at 0 rpm when standing still and has max torque when at 0 rpm, flooring it from standstill would be a great feeling.. if only they thought of some batteries that could give a reasonable range and fast charging...

Let's not confuse the DSG with a Tiptronic or other paddle-shifted automatic (with torque converter). The DSG is a great bit of mechanical gear, using twin clutches for seamless power delivery. Much as I like rowing the gears on a conventional box, the DSG is a fabulous gearbox and I wouldn't hesitate a moment to get one.

[Scottieb]

Easy, a Z20 LET.  Gives you all you want and more.  Bolts straight in

Well you must have one that works properly then mr partridge but for me, the difference between the power delivery from the VXT and the power delivery from the Honda is like the difference between eating a meal in a pub thats "part of a chain" and one thats independant

Funnt you should mention that - I have often dreampt about it. Remeber that japanese prototype people carrier they did about 5 years ago? it waye tonnes, it had a motor in the hub of each wheel and did 0-60 in about 5.5? hmm... Battery technology is still not good enough though, although lithium technology is getting very good, just dont go though any fords

[Black Knight]

This is about it..




features - clicky here

Looks great for track use.. And has all it needs.. double wishbones front and back, coilovers etc
And the powerplant couldn't care less if you push it to the max 100% of the time...

Only the price is a "bit" high... but something like this can be built as hobby in a garage easily for cheap money..

What would you have to do to put in the turbo engine (from vxt) to a na ? Would it be just the engine change or do you need to change the gear box etc.. I think i could get that engine from astra - it's the same ??

[Black Knight]

i think it'd be cheaper to get a SC conversion... and also better for the car weight, handling and also instant throttle response - no turbo lag..

Courtenay-sport will do it for you.

IIRC you have to change the rear-subframe, ECU wiring loom, cut a hole in the rear-clam and install turbo ears... etc

You would be better off selling your NA and buying a turbo IMO. Cheaper right now...

Is a Honda lump really that much lighter than GM 2.2? I always thought that Jap engines were 'over-engineered' (strong as fcuk!) Which always meant they were great for tuning (especially the old iron blocks from Skyline/Supra/Silvia) Does anyone actually know the precise weight of all these engines???????????? Would be interesting to have a list somewhere. To the point: My choice (for track) would have to be either tuning the nuts off the current 2.2 and / or supercharging it. For road use, you probably can't beat the 2.0 turbo. Tourque is king on the road..................................

[JohnyB]

thanks ... i thought it would be easy

That V10 is one of, if not the best motors around. Likely wayyy to heavy for practical use in our cars, and I'm sure you weren't serious anyway. Anyone mention a forced-induction rotary yet? Twin-turbo beer keg would be kind of nice, but the rebuilds would wear you down eventually...

It's the E39 M5 V8 not the new V10, not that it would make much difference as far as fitting it in would go

Well said that man. I have shelved my K20A plans. The Honda Vtec is a great engine, but the need to rev the nuts off it to extract performance (the reason the 111R fails), means it will never be as pleasant or fast on the road as the VXT

[mainline]

Fcuk it



Would it fit, no idea, probably if not definitely not, but hey it is a fantasy engine swap.
