Mat Jackson Posted June 25 Share Posted June 25 Im looking at potential buying a 1600 Road sport, currently running 140 BHP, but would ideally like more power. Its already running ITBs and has a 636 cam fitted I`d like to source and build an 1800 unit with VVC head, and add in QEDs fast road clam, which claims an increase power to 175 BHP with the TB set up. Has anyone else got any experience with QED and this set up, or any other recommendations for tuning to this level. I dont want to do much work on the bottom end (so head and cams) and also want to keep it driveable as a fast road car. Previous experience was a Westfield with 200bhp, so looking for w similar set up Thanks, M Link to comment Share on other sites More sharing options...
DirtBuddha Posted June 25 Share Posted June 25 I have a low mileage 1.8 VVC engine from an MGF complete with all the VVC stuff available in case you need one. Came out of a car that suffered front end damage. £995 located West Sussex. Link to comment Share on other sites More sharing options...

Englishmaninwales Posted June 25 Share Posted June 25 (edited) The EU3 VVC with K Maps ECU gives a nice upgrade circa 160bhp.. Edited June 25 by Englishmaninwales Link to comment Share on other sites More sharing options...

Mat Hi, no it’s from an MGF. Same engine though… IIRC the car had only done 32k miles when it was crashed. Link to comment Share on other sites More sharing options...

Is that keeping the VVC operational or just using the VVC head? Apologies, not familiar with K Maps - any details on this? Link to comment Share on other sites More sharing options...

Miker7 Posted June 25 Share Posted June 25 QED supply parts, DVA will supply or (used to) fit. Link to comment Share on other sites More sharing options...
Miker7 Posted June 25 Share Posted June 25 I'm looking for a similar vvc engine, however I've been warned to expect problems with heads in most engines for sale on eBay. If this engine hasn't overheated - you're doing well and onto a winner. Unfortunately, like most things I want everything cheap so it's out of my price range.

Apologies, not familiar with K Maps - any details on this? Kmaps.co.uk will uprate your ECU (EU3 only) and keep it MOT compliant. This keeps the existing 1800 configured withVVC mechs. But 160 is as far as you can go keeping this configuration Edited June 25 by Englishmaninwales Link to comment Share on other sites More sharing options...
Miker7 Posted June 25 Share Posted June 25 NB general wisdom (ie from DVA aka oilyhands on this form) is that the standard pistons shouldn't go above 7200. Only the mg 160 pistons or aftermarket should go higher. There's is a known weakness with the piston rings (?? I can't remember, Google is your friend). I'm mentioning this as I think k maps don't lower the Rev limit & so you will have to be careful. Link to comment Share on other sites More sharing options...

I'm mentioning this as I think k maps don't lower the Rev limit & so you will have to be careful. For information, it is the ring land between the top and second ring on the thrust (inlet) side that fractures, followed by loss of compression and piston disintegration. The 160 pistons have a thicker ring land, smaller valve pockets and extra buttressing under the crown adjacent to the gudgeon pin bosses, this strengthens the pistons considerably. When 160 pistons are used in a 1600 there will be issues connected with the smaller valve pockets as the pistons sit 1.4mm higher in the bore than on the 1800. Most of the pistons shown here are from standard 1600 and 1800 supersports, one is from a standard 1800. The failure point is so consistent that you can almost take a fractured land from one broken piston and place into another.

Roger King Posted June 27 Share Posted June 27 Yes, that's a common failure with Supersprint Crossflows as well, due to using 1300ccm pistons designed for 50bhp in a (claimed) 135bhp application revving much higher than standard. Link to comment Share on other sites More sharing options...
Area Representative Golf Juliet Tango Posted June 27 Area Representative Share Posted June 27 I think you will find buying a car with the engine spec you want is cheaper than buying a car then separately getting the engine you want built. Link to comment Share on other sites More sharing options...
D Jones Posted June 29 Share Posted June 29 If you need to know how much things cost in the current market (last year) have a look at my blog It make the upgrade route illogical, better to sell and upgrade the car but, when did logic ever get in the way of emotional attachment to a car 😀 Link to comment Share on other sites More sharing options...
