    Just for info, that is the main pressurised feed rather than the return so it needs to be resistant to the pressure (stock fuel pressure is 3 bar/44PSI). Oily

    The immobiliser is off by default when you have an Emerald installed. It can be turned on in the software if you require it.If you dont use it then it can just be left. Some immobilisers work by disabling the starter, these dont involve the ECU. If you remove the immobiliser and you have a stock ECU the engine will not start. On later ECUs (mems3) the immobilisor can be coded out. Oily

    Ah.. thought it was 23rd May, my mistake.. Dave

    Andrew, you have altogether too much time on your hands ;). Sterling work... reminds me of decompiling BIOS code many years ago on PCs to find disk tables and fit larger disks. It's quite a high when you find that vital piece of code/data, correct ing the checksums is always fun.. How did it go at NMS? Oily

    Yours will most likly be a Mems3, if it doesnt have a distributor cap then it will be Mems3 Oily

    Send a pic of your cambelt area with the cover off and I will tell you, if the engine is the original and pre-1999 then it is likely to be manual, if the engine is EU3 (no distributor cap), then it is likely to be an auto. Oily

    Mems 1.9 might be a problem, have a look at rover Mems.com, Mems3 is a more straightforward proposition, Andrew Revill (Revilla) and Kmaps can modify these. Oily

    Sneezing is usually lean fuelling, timing hopelessly retarded or incomplete combustion due to unsuitable or failing plugs/leads/coil. If you dont have resistive plugs I would start there.. Oily

    As well as accelerating the car, the engine has to also accelerate its own mass, the lower the inertia of the engine the faster it will accelerate itself, this improves the acceleration of the vehicle as a whole, especially in the lower gears where the mass of the engine is a greater proportion of the overall mass. The rotating moment of the flywheel is quite high so removing mass, especially at the outer reaches of the flywheel has a profound affect. oily

    Just for info.. SS cams hydraulic - Inlet 50 thou, exhaust 44 thou lift at TDC SS cams solid followers - Inlet 59 thou, exhaust 47 thou lift at TDC Oily.

    It is not uncommon for a TPS to bind on the end of a throttle shaft, it happens on just about every set of Jenvey TBs I fit which retain the OE TPS, so I always space them on the mountings to ensure this does not happen. Oily

    Yes and I used that type exclusively from 1970 until around 1998 when I made my first sleeve. For an amateur builder the sleeve makes a lot of sense, the first post here shows the difficulties that are faced and the damage that can result. Why take the chance? Oily

    The problems with these are.. 1) they grip the piston which means a lot of effort is required to insert the piston to the bore, (I've seen them tapped with the handle of a hammer), if a ring snags you wont feel it and will probably damage it 2) they are spiral wound and can easily displace in use allowing a ring to creep out just before entering the bore. 3) they are a faff to use as they have to be wound/unwound on every use.

    I use a tapered piston sleeve which compresses the rings, but does *not* grip the pistons, this makes assembly easy and safe and incredibly fast, the chance of ring breakage is minimal and very little effort is required to push the pistons into the bore (one finger); if a ring snags (which is unlikely), then the resistance is easily felt. The top of the liner is tapered to allow entry with the rigs expanded. The sleeve is made from an old liner of the correct size, but Wiseco produce piston sleeves in a variety of sizes. These are very effective and cost less than a ring set. Oily

    The Mems will not run the engine that well, engine load sensing on the Mems is via MAP (manifold absolute pressure), this requires a vacuum signal from the inlet manifold which is not easy to arrange on the Jenveys, also the IACV is an integral part of the Mems strategy and this is not used on the Jenveys as there is nowhere convenient to plumb it.. With TBs you really need an ECU that uses Alpha-N load sensing (via the throttle position sensor), I would bite the bullet and get an Emerald, it'll save you some aggro. I have a number of maps that would suit your engine. /Oily

    Sadly not available. Originally Bernard and I canvassed owners to see of there was interest and had a number of interested parties so some were made, by then most of the prospects had gone with Pipercross airboxes (some of which fell apart I'm told), as there were few takers the molds were not adopted by Eliseparts and the boxes are nor more...

    I have a number of them here if you don't mind secondhand, from 1996-2000 non VVC and VVC are the same. Oily

    Yes, no problem,but you may need to swap to a manual tensioner if the head isn't drilled/tapped for an auto tensioner. Not all early heads can be drilled and tapped for an auto... some dont have them supporting material for the threads. Don't worry about grouped injection, all of the RX00 engines ran batched which is more retrograde than grouped, the SLRs ran grouped. Oily

    The Emerald ECU plugs straight in to EU1(mems1.9) and EU2(Mems 2) looms, on EU3 engines they can supply a plug and play adapter or you can hardwire. Oily

    I dont think you will see a 10% increase from a remap. However using an aftermarket ECU that doesn't use manifold pressure to assess load will allow the cam timing to be made more aggressive which could improve things significantly. With the VVC head you could choose a hotter inlet cam which might well improve things further. Oily
  25. oilyhands
    Your engine is an EU2 so it has a manual tensioner. You will need a new inlet cam with larger journals, a VVC blanking kit, modification to the cambelt rear cover, a drill and tap under the exhaust cam nacelle, modifications to the rear blank kit to accommodate the distributor cap, a rotor arm spigot, new leads for the taller head and some modifications to the plenum to match the inlet ports. If you have solid followers you will need to swap over the valve spring caps and re-shim the followers. If your followers are hydraulic then you can use the VVC followers which are superior. I'd say around 160BHP would be about right but the stock ECU *may* struggle with the fuelling a little. Make sure the VVC head is viable, a hardness test is compulsory. Dave
