Gary-Cornwall Posted April 23, 2002 Share Posted April 23, 2002 Considering the above for my current live axle grad spec at the end of the year. Can anyone give me a quick summary of the changes that will need to be made. The ital axle will be replaced by a Ford one. Can I keep the 40's? I know stuff like brakes etc should be considered but at this stage I just need to know the "must do's". What about the bonnet, Sierra box etc? Any help much appreciated. Roger, Barbara, I knew that passenger ride was a mistake! Link to comment Share on other sites More sharing options...
EFA Posted April 23, 2002 Share Posted April 23, 2002 Assuming the Grad car is a VX 8v , all the bottom end bits are the same fitment - i.e. engine mounts, bellhousing, gearbox etc. If its an Xflow, all are different. So assuming its a VX you need: New carbs (min 45's) if you want any serious (over 150bhp) power. New inlet manifold New exhaust manifold Probably a new bonnet Brake swill be OK unless you go over around 200bhp. Rogers car is 250bhp!

Area Representative Tin Man Posted April 23, 2002 Area Representative Share Posted April 23, 2002 Gary, are you going for 200BHPteeth.gif Fancy a blat on Thursdayquestion.gif May see you tomorrow. Link to comment Share on other sites More sharing options...
Gary-Cornwall Posted April 23, 2002 Author Share Posted April 23, 2002 Arnie, thanks for the advice....I knew I could rely on you for help with VX issues. Yes its a Vx 8v. Any thoughts on whether to keep the original bits to revert back if required for resale or just use them to fund the upgrade? Tinman - I'll just settle for 150ish for the time being. But at the rate you're improving both driver and car (Coombe!) I reserve the right to future upgrades as required. Thursday sounds good...watch the weather.

EFA Posted April 23, 2002 Share Posted April 23, 2002 Gary, Ditch the 8v engine and slot the 2.0 XE in. What you will save on carbs at 150bhp on 40's you will lose on having to get the engine professionally mapped. Buy one of the 2d systems in the for sale sectio - 175bhp on twin 45's on a std engine with Caterhams manifold. I am sure someone on here is thinking of an injection upgrade so getting the bits shouldn't be so hard.

C7JFM Posted April 24, 2002 Share Posted April 24, 2002 Gary....i'm in the process of doing just what you plan to do. You will need: engine caterham sump twin 45's weber or dellorto 2d ignition module hoses inlet manifold exhaust manifold I'm not sure about the bonnet yet I plan to keep all the old 8v parts so that when and if i come to sell the car I could return it to normal spec or sell it with two possible power plants.

EFA Posted April 24, 2002 Share Posted April 24, 2002 Why can't you use the 8V sump?? IS it not a finned ally type? Fat Arn Visit the K2 RUM siteid=red> See the Lotus Seven Club 4 Counties Area Website hereid=green> Link to comment Share on other sites More sharing options...
C7JFM Posted April 24, 2002 Share Posted April 24, 2002 You are quite right. I however decided to keep the old engine intact with its own sump to keep the dirt out of the bottom end while storing it and so that I could do a quick change back to 8v when I feel like sprinting in class 1.

Gary-Cornwall Posted April 24, 2002 Author Share Posted April 24, 2002 Arnie, Chris thanks again. I have read in several places that 45's are the way to go with this engine but would the existing 40's be feasible at least in the short term if cost is an issue. Why the 2d ignition module? What are the reasons / benefits? Link to comment Share on other sites More sharing options...
C7JFM Posted April 25, 2002 Share Posted April 25, 2002 With ref. to the 2d ignition module. The existing igniton module on your car is not suitably programmed for the 16v engine. You would therefore need to either reprogramme it or replace it with one from a 16 v car. I got mine from a fellow blatter. Link to comment Share on other sites More sharing options...
Gary-Cornwall Posted April 25, 2002 Author Share Posted April 25, 2002 Thanks Chris. What sort of cost are we talking about here? Link to comment Share on other sites More sharing options...
C7JFM Posted April 26, 2002 Share Posted April 26, 2002 I think I will have the whole lot fitted and running for under 1.5K (the wife thinks alot less). it is a much better route to more power than an 1800 conversion IMHO. But dont forget this is a disease and big brakes, suspension, ford axle, LSD, and throttle bodies all threaten to make think why dont I buy L7FUN.

Gary-Cornwall Posted April 30, 2002 Author Share Posted April 30, 2002 Chris, surely you're not going to swap engines before replacing the Ital Axle? What's the best source to find the engine? Thanks for ongoing help. Link to comment Share on other sites More sharing options...
oilyhands Posted April 30, 2002 Share Posted April 30, 2002 Err.. sorry to butt-in but I just happen to have a 77,000 mile red top C20XE Vauxhall 16V engine sitting in my shed looking for a good home.., its complete with all ancilliaries , is in good running order and I *may* be able to root out the ECU.

C7JFM Posted April 30, 2002 Share Posted April 30, 2002 yes...I'm going to put all that new power through the ital axle...until i fit the english axle that is sitting on my garage floor. Link to comment Share on other sites More sharing options...
