BX 2.0 CT Turbo, it begins....

[Tim Leech]

Cheers guys, the saxo engine has less power than i have now

I'll bet you £1000 it doesn't!

The 8v is rated at 90bhp and the 1.6 Bx at 92? The later VTR was 100bhp but even so its not what I had in mind, i want something that shifts!!

[Henry.M]

might be agro putting it in and finding one but what about an xantia 3.0 v6 , 188 bhp and sounds beautiful.

Trust me henry a V6 is way beyond my skills!

It would be easier to fit a rover v8 than one of them. Far too fat and complicated.


Tim, I think you need something simple and pre 1996 (when everything seemed to suddenly become electronic), or modify the hell out of something that already exists, like sticking a 'soft' super charger on the engine you already have?

A big (displacement) engine is not needs be a powerful one, as Mr Allard proved with his 350bhp 1.5litre diesel in the late 70's (i think).

If you've really got to have power, hows about this?

Thanks Vanny, im still thinking Mk1 Activa turbo engine or Mi16

Forget all the book-figure bullshit, actual real world horsepower at the wheels stuff, the TU would be better.

You sold the 16v because you didn't drive it the way it was intended, and now you want to go to enormous lengths to fit an engine (which isn't actually all that good) to a BX. Or worse, fit a BX 16v engine to a non-16v BX. What? I don't even.........

If you want a different BX that shifts, start with the BX that is the quickest, then fit a V6 engine. Done.

I've got a good grey donor here

Its been done to death in a 205, google it, basically you stick the battery in the boot (which is a doddle mind) and put the turbo where the battery was, with some trick exhaust. Kits come up on eBlag from time to time. Oh and on 205GtiDrivers.

The above seems somewhat more complicated than fitting the diesel turbo and associated pipework of the BX to the petrol 8v GTi engine so presumably that's not an option that fits/works or could be easily modified to do so?

[Tim Leech]

Interesting, isnt a tu engine the other way around from an Xu? Ie inlet and Exhaust being back to front?, seems an awful lot of extra work where as the xantia turbo or mi16 is at least a xu in one form or another. Youre right Kitch to say I didnt drive the grey one hard as unless you "rung its neck" it wasnt quick, ive never been one to have the engine screaming much preferring torque to high revs horepower hence the original post, if a mi16 is the route I go down it will be mated to a td gearbox so I can enjoy relaxed cruising and a bit of fun should I choose to change down the box and give it "the beans".

The boasts of 150+hp from a tweaked 1.9td elsewhere on here sounds interesting too but intended to stick to petrol as i thought it would involve less work?

The original post was to ask if it is feasable and what kind of works involved.

Ive looked at the 205 driver club and it seems that a pre 96 Activa/406 2.0T engine is the way forward as it has a keybad immobiler which can be bypassed.

I still am open to ideas, initial cost is important than actual fuel economy.

You're best off with an 8v or turbo power - if you put a TD box on an Mi16 engine you'll just kill the speed because it'll fall out of the power band on every change.

For what you're after, the 2.0 Turbo is probably the best option. To get an XUD to go as well as a TCT would require lots of tuning, but then it wouldn't be as hard to install in the first place.
Don't get too hung up on the immobiliser stuff....you can unlock the coded ECUs.

But it's like I say....you're best off to start with a 16v, because it's got the best chance of handling the power. A TRS setup is just going to pitch, dive and generally wallow around while screaming power away on the inside wheel.

Best of luck to you, but I think I'd go 2.1TD and tweak it myself.

I guess that depends on how it's driven though - true if you're slinging it around corners but if you just want a cruiser that pulls strongly whatever gear you're in, then it matters less. I would agree that the 16v engine isn't right for that kind of driving.

When I first fitted the 1.9TD engine I was impressed with the torque off boost, and that made it a lot more relaxing to drive normally, compared with the 1769cc unit. You cold generally potter around in a gear higher than you could previously. Now it's running higher boost, it actually feels flat in comparison before the turbo spools up, so although more fun might not be what you're after.

Im not one for screaming round corners, I just like straight line speed/acceleration. I thought that a BX 16v was mechanically similar to a normal BX asides the engine of course, front brakes (an easy bolt on upgrade), different spheres and thicker any roll bars?

Im not a fan of the all black interior and like the softer ride of the non Gti BX's so that coupled with something that will get your pulses races if sounds like BX nirvana to me!

Yes but the thicker anti-roll bars and the harder spheres make a huge amount of difference to how they go around corners and significantly harden the ride… I think Kitch is almost certainly correct that for the 2.0CT engine may well suit you fine as it produces a broad band of torque and in a BX which is 250kg lighter than an Xantia will be very lively – you can use gearing that's higher than the Xantia's I would think.

[Tim Leech]

Thanks Hilary, the idea is to have a comfy cruiser that can get from 0-60 quickly if required but sit on the autoroute at 80-90 without being intrusive.

[Kitch]

The CT is a good cruiser, for sure. But don't forget it uses the ML5T gearbox, which (although arguably nicer to use than the BE) is feckin big and feckin heavy!

Didnt know that Kitch, thanks, will it fit in a BX? or will a BX TD one have to go on instead.
