It has made my day seeing this car on here! I'm sure I saw this car for sale a few years back, standard even down to the original wheels. Absolutely loved it then, love it even more now, those turbovecs are ace! God I wish I'd had the money to buy it back then! ah yes. i brought this from a girl in chichester. was very, very cheap.

Sadly, even cheap was too much for my pocket back then! It was nearly always parked a couple of doors away from me, was torture seeing it every day! Still, it's in good hands, that's the important thing!

LSD is a little sensative for a light car but it does make it quite fun to drive ;D

well it's been a while. i have decided to sort the front end of the car which means pulling out the front cross member to clean and paint as well as replace some of the ball joints for new ones. they aren't worn but as it gets used on the track it never hurts to replace things like these cross member is very good apart from lacking paint in a few places. as it comes out so easy i may as well sort it once and for all. the front tie bar brackets will come out to get the same treatment. some of the other jobs are to change the bend on the exhaust manifold for a mandrel bend and to tidy up some of the wiring and make a few brackets to make things look a little tidier. some of the wiring needs a little tidy up. i have decided to remove the fuel injection system. it has never been 100%. there is always something not quite right as it is a hybrid system and a few bits missing like the carbon canister etc. tick over would never really settle down and even though with some fiddling i got it a lot better i could never get it spot on. late fuel injection cars are too sensative to any changes so i think the modified exhaust manifold and inlet pipes were not agreeing with it. i think the lambda is a little slow as well. as it isn't a daily driver i may as well go old school and fit a set of carbs. modern fuel injection doesn't dump loads of fuel in the system on acceleration like carbs do because they have to look after the cat' and be enviromentally friendly. carbs should wake the engine up a little. just got to decide which carbs to fit then i can make the inlet manifold. from what i read the VVT unit is pretty much on all the time apart from tick over so a simple microswitch or even jam the system in the position that gives best power.

with the fuel injection it was a little bit too user friendly and just didn't feel sporty enough if you know what i mean. i know in a way carbs are going backwards but the modern generation can't seem to get their head around them and really haven't a clue how they work. once set up they can work really well. anyway iv'e been messing with the exhaust manifold i quickly knocked up a jig to hold the end in place while i cut out the offending bit and replaced with a manderel bend. (arrowed so i can trial fit without getting it the wrong way around and grinding the wrong bit off) the manifold flange needed a bit of fetteling as well to get rid of some of the restriction when back in the engine bay i'll probably leave the big heat shield off as it makes it look a bit more technical

just to see what happens i'm going to have a play with the fuel injection to see if i can make it work a little better. it wont cost money just time so if it doesn't work there isn't anything lost. plus i could sell the bits on anyway. one thing i noticed when the car was running was that the inlet manifold was as hot as the engine itself. a known way to lose a little power. so i'm going to remove the Exhaust Gas Recirculation system and block off the pipes. the EGR is another way that the engine will heat the inlet. iv'e also removed the coolant pipes from the throttle body to stop that being heated and iv'e knocked up a spacer so the manifold can't get it's heat from direct contact with the head. some sort of bakerlite but it is layered and extremly strong. modded the throttle by thinning down the spindle and smoothing the inlet and outlet part of the body by the butterfly and just fetling the inlet manifold. i is a very large bore until it just goes into the head so i'll only enlarge the last part of the runners

well a bit more research and i got the tools out to do some more mods to the inlet cutting the centre out of the top part of the manifold will mean the runner length will be back to about stock with the addition of the heat barrier inlet spacer rough cut finished it does mean the space in the plenum is larger but the research suggested that a larger plenum helps power. it can cause throttle lag if too big but the size hasn't changed too dramatically and the engine was very blippy anyway. this left the runners with a sharp edge. not good for flow. so i got the grinding wheels out again in theory it should all make an improvement but as i had no dyno power outputs to compare it with i'll probably never know?
