They vary depending on who built the engine. The Caterham ones were standard Ford cast items and then lightened. I am not sure of the weight but its heavier than the Burtons steel versions. I have a Burtons steel version of 5.2 kg (I think) which is perfect for normal road use and is also strong for high revs. The next step is for an engine builder to machine slots in these to reduce to something like 4kg but not really necessary for the road.

I had a VVC Elise, model 111s. Very good engine, nice level of performance, good fuel economy etc etc. The 111s also had different gear ratios from the non VVC. Only problem was annoying reliability issues due to poor build at the factory all of which will have been rectified on a well maintained car (mine was new so I had to sort them out). My old 87 XFlow 7 has survived alongside all of the other more modern cars I have had. Much more satisfying in the end.

It wont make any noticable difference other than they look fantastic, but you wont see them! I found that the roller rockers wear (on 2 sets) and so any less wear in the valve guides has been replaced by a new problem. Best to fit an uprated rocker assembly of the original design which is available from Burtons or others. I have gone back to this set up on 170 bhp X Flow. I hope that helps. George

Just had my car checked and set up on the rolling road to eliminate a misfire on twin Webber 45s on a recently improved crossflow and thought the contact details might be of use to others. Frost Motor Services in Ipswich 01473 250 996, contact Rindy carried out the work. They were recomended by Scholar engines. They were very helpfull, reasonably priced and they sorted the problem. The car now runs superbly with fantastic torque so the engine upgrade is now complete.

1700cc Accralite forged pistons, polished and lightened con rods with ARP bolts, tuftrided and balanced crank, uprated bearings etc. All run as a set with low mileage from new (road use and one track day) and suitable up to 7500 rpm. Will be inspected by professional and the crank will be crack tested. New rings etc can be provided if required. Available due to upgrade and can be inspected as my engine is stripped for upgrade. £ 700. 3 D Weber Alpha wasted spark ignition kit (ECU, wiring loom, temperature, throttle and crank sensors) supplied by Roger King (and mapped) for 155bhp X Flow (parts above). Rev limit set at 7500 - phased to 7700. Good condition etc. Instructions available and still in car (without engine) to see how it all goes together. £ 400. Location - Nr. Stowmarket, Suffolk.

Frost sell a glass polishing kit for around £ 20. I have tried this kit and it works very well although it has its limits and you need to take care.

I am near Stowmarket. If of interest please e mail me.
