does any 1 know how much extra bhp a chip and remap will give my mg zr vvc 160? and what other modifications i can do to get more bhp cheers :)

Full Janspeed exhaust system, so 4-2-1 manifold, sports cat, midpipe and backbox all by Janspeed, ITG air filter and then a remap by 'Z and F Tuning' (member on this forum) and you should have a healthy amount of bhp increase as well as more torque. I'd say about 175bhp ish, maybe more.

Not a massive you can do on the cheap tbh, Cat-back exhaust and induction like has been said. But to get anything above 5bhp-ish your looking at alot of money.

On a side note, where in kent are you from, and welcome to the forum. :D and pics of car are needed

what ever u do dont bvut any chips unless they r the kind u can eat with salt and vinegar. The chips r a waste of time all they r is a bunch of resistors that fool the ecu into over fueling. all u will end up doing is ruening ur engine, fuel econemy and bank ballance.

If u realy want a more powerfull car go buy one off the forecourts. i never understand why people pay thousands on suping thier cars for very little benifit when they could buy a car with more grunt and insure it as standered for less money.

Well it depends, not all cars are uneconomical to modify. I can get you from 105bhp to 135bhp for less than 50 quid had it been a rover diesel engine.

Also not all chips are bad, chips come from the good old days when we'd remove the e/eeprom's from the ecu and remap it by replacing the physical 'chip'. Yes they are mostly scamming resistors these days but the real thing still exists too for those that are careful from who they buy their products.

Incidentally my car is heavily modified, the only reason I didn't recommend it in this situation is because most mods on this engine will either cost loads or amount to an unnoticable difference.

^ by chips, i'm pretty sure he means an ECU piggyback (like a megasquirt or the likes), which is soldered into the ECU and makes it more (if not fully) programmable.

Also, heavily modified cars are actually cheaper to insure when done through specialist insurers. My ZR Rally car actually costs less a year than my Road-one did. And my Rally one is still registered as a ZR160, even though it's got a 1400S engine (150ish BHP).

is the ralley car insured to drive on the road more than to and from the meetings?

i guess i should clarify my post. there are applications to modifying engines there r several people on the forum that seem to do track days, rallying, hill climbs and the like. They spend huge amounts of money upgrading all sorts of things and thier cars r built for a specific job. However the average person just wants to get from a to b quicker and this is the part i dont understand. 3-4 k to upgrade various bits that r usualy done in a haphazard piecemeal way with no real thought of how each bit will work as a unit when as i said they could spend less and just simply buy a more powerfull car that is built to withstand the bhp etc for less money.

I see where you're coming from, but there are situations where people who want to get from A to B quicker can do it cheaply. For example to get a derv (sorry for all the diesel talk, its the side im active in) to 150-160hp territory you're talking about three hundred. So it's like a cost of an induction kit and a backbox.

That said I'm way beyond that, I've spent about ÂŁ700 on mine, shouldn't be far off my target of 200 ponies now. Most expensive bit was the clutch.

I was hoping that my service was a little better known by now - although one member has already kindly mentioned ZandF in the thread..

I offer quality mems ecu retunes (after all I was the engineer who developed the cars in the first place) and can provide an instant 10-15bhp vvc power boost by altering the rev limiter in my phase 2 retune. Note the recals are also about enhancing response in all driving conditions and not just on the red line though...

The service (www.zandf-tuning.co.uk) has had many forum reviews - heres a few links..

Finally, the benefits are apparent on standard exh/intake systems with any tweaks along these lines simply adding a few more percent ( and a bit more noise..)
Oh, and Ive just announced a flat ÂŁ199 retune fee for any recals obtained at MGFest Gaydon on 1st August (vvc recal is normally ÂŁ259)

Cheers

^ I recommend Zandf-tuning.

Had some ECU work done on one of our cars back at Silverstone, and our drivers were greatly impressed by the difference of the car. This was on a 3rd party ecu, but still, very good service.
