KV6 190 - Upgrades??
Morning,
I'm well aware there's a few threads on this but a lot of them are quite old..... So can anything be done to improve the 190? as it stands i already have a larger stainless exhaust and a K&N drop in filter, Shannon tube is new. Just after some more power, i mean if nothing comes up here then i'll grab a spare and get it to an engine builders next year.

As a NASP engine and a MG Rover engine there is not much you can do. From my research as I am planning to do the full monty when funds are available. The following can be done:
Performance filter (panel/cone) Stainless steel exhaust from the exhaust manifold Piper cams Cylinder head poiished and ported Remapp The above is off the shelf bits and my VERY rough calculation should take it from 187 to 220 and very expensive lol . According to info I have found on the net the componants on the zt were rated upto 220 so I am not looking for silly figures. Even JC on Top Gear said that a boffin at SAAB said that for a front wheel drive car the most effecient power delivery is 220.

I'd be over the moon with a reliable 220 nasp... i mean 240/250 would be amazing but without going down the re-bore/crank etc its not gonna happen.

You would have to spend alot of silly money to get 240/250 and the engine was never designed to go that far. Plus you would have to start thinking of changing orther parts to handel the extra power eg up rated clutch.

I know of plenty of front wheel drive cars that are pushing more than 220BHP.
I didn't realise these engines were so bad at getting past what is the allowed extra BHP. Even the diesels you can't push too far because of the cast cranks. Does make me wonder if a complete engine swap might be a better option with a different manufacturer.

I have seen the Top Gear programs where cars are doing 220plus bhp, but the exrta power to me seems only useable in a straight line.

Wasn't there a chap in the north of Scotland who was using a modified KV6 in a off-road rally buggy type car? I've definitely warn YouTube clips of it tearing around.

No, the kv6 is not related to the ronda (twin cam) 2.7. It is a developement of the late rover 827 engine though (and probably the sedona), and that one did have an alloy inlet manifold.
I'm not on a downer on the inlet manifold as its used, just that it makes tuning difficult. Is it restrictive? i dont know, but it doesnt look it, and anyway, if it was, that would be at the top end, and my 190 goes all the way to the red line without issue. The exhaust manifold is another matter though... There is a 2litre autograss kv6 around, had a steel crank, cams, forged pistons. Went very well, screamed its head off. |
