Hi all
I've had my 3.0 elite for a couple of weeks now,clocked up a 1000 miles in it,with no problems
Now this may seem strange ,as its quite quick,but I feel it has a lot more to give,performance wise and was wondering,what if any aftermarket performance mods are available.
Any advice would be helpfull.

MTek chip - PM him

Cheers will do  
Am i right in thinking there is a limiter on the Elite as well,
May as well get all the dumb "Q's" out of the way in one go
Plus better explain I'm a older guy not a youngster,so any performance gains neeed to be stealthy LOL,don't want to let everyone know I'm coming from 10 miles away 8-)

The only reasonably cheap thing to do is the chip, about £160.  Improves top end, increases drivability mid range.  Gains aren't huge, remember, normally aspirated, so not huge amount can be done from mapping point of view.

The manifolds are restrictive, but yet to find decent replacements.  Not convinced decatting will improve matters much.

Silly induction systems seem to lower performance, but increase noise - so sounds like you won't want to go down that route.


Lastly, check your existing multirams are working. Fairly common for a problem with these, and they will affect performance.


BTW, no limiters on Omegas (other than the redline rev limiter).

thanks for the info ,so basicaly leave it alone ,it's quick enough LOL

I am mulling over fitting a nitrous kit to the MV6 for a bit of fun...  

[TOOL]

COOL 8-) not where i want to go though LOL
been down the ...err nut route to many times,260 bhp Eclipse,300 bhp R33 and a 400bhp WRX
want performance with comfort now LOL

In addition to what my co forumists are saying i would suggest that the best way to tune the 3lt engine is by doing the following mods. You need enlarged throttle/cams and mapping on a dyno by a person tha knows what he is doing. Chips are good but not good enough as usually they are modified standard maps and they are NEVER developed on a dyno. So eventhough you could get some extra performance you might actually strain the engine too much for no gain. For example in order to determine MTB(ignition timing point where the engine produces the max torque) ignition timing point for every throttle % and rpm increment you need dyno and a lot of time tuning. Having tuned engines myself i have found that for example on a rover K series you get 80NM with 3/4 throttle and 2000rpm at 20degrees BTDC ignition advance while remaining inside cylinder pressure limits while at 25 degrees the torque stays the same and the peak cylinder pressure goes sky high which on a long run will ruin the engine.

which on a long run will ruin the engine.

Can a K series do a long run without popping the hg

Depends what you call a long run - feet, yards, miles...?

It is not too bad you know, a friend of mine is running 130bhp on his rover 200 rally car 1.4.

right so it's not going to be a DIY job then
just an update decided to try to improve air flow by fitting a large cone filter and a direct cold air intake,these were originaly of my Skyline and were just lying about in the garage.
Well apart from a very nice noise can't see or feel any improvement LOL :)must be loud from outside as pedestrians keep turning round when I drive by ,think the original air box will be refitted this  8-)weekend

I've seen a 1.8 K series make 253BHP on an accurate rolling road. Not much of it was standard though. Certainly none of the moving parts! That was at circa 9,000 RPM by the way

They can be made reliable these days if you use something like a scholar conversion that keeps the liners located more accurately. Deep pockets required though.

I can't imagine a cone filter would improve the Omega much. The designers wouldn't have gone to all the trouble of fitting the multiram system only to put a restrictive airbox on it, and the air intake is right at the front, making best use of the cold air.

On my last car I rebuilt the engine and after a few weeks noticed a big drop in power once it had warmed up. I found some of the intake ducting had come apart so it was drawing air from the engine bay rather than the normal location in front of the radiator. As soon as the engine warmed up the radiator started flooding the engine bay with warm air. Do not underestimate the importance of a cool intake charge.

Which explains why I have always felt that my car runs better at night then!
