Hello all I am in the process of fitting EFI to my spitfire and I am thinking the Alternator is not going to be up to the job as the fuel pump runs all the time and pulls 7.5amps At the moment I have a Lucas ACR 15 fitted which is 25amp I was thinking of one of these type http://www.ebay.co.uk/itm/Genuine-Denso-12-14v-Alternator-/282341548231?hash=item41bcde20c7:g:BIMAAOSw5cNYjQW8 http://www.ebay.co.uk/itm/Nippon-Denso-small-Caterham-Westfield-race-alternator-kubota-yanmar-/332108148633?hash=item4d53302f99:g:Ml8AAOSw44BYjvDu What do you all think? Roger

Hello All A bit more progress exhaust fought back on!(mine has the center box and if you do not get it in the middle it rattles on the body)but it does make it a nice sound for a twin pipe type and not to loud. I have wired in the lambda sensor and display. So I thought today I would wire up the fuel pump so had a look at were Triumph run the cables and guess what the passenger seat is now out seat belt diconnected(to lift the carpet) hood frame unbolted and the trim revoved off the 1/4 panel!!!!!! All this to run a cable through? So just the reverse to do now and of course connect the pump cable. Still getting closer to trying to start it(I think it may be getting to me as I dreamt last night that it started and sounded good but then the brakes did not seem to be working? but I woke up then!) Roger

Hello All A bit more progress exhaust fitted(well most just back boxes to fit) Air box fitted but unfortunatley I rush the paint job and it has all wrinkled(still will do for now) Sorted a bit more cabling out and put sleeves around fuel pipes were they may chaff and cliped down. I think tomorrow I will see if I can set the throttle plates to be in sync and finish pump wiring. Then should be about ready to try and fire her up(I may check all wiring first?) then the fun will start? I am pleased with the fuel filter position under the tank. I went with the 25 mm trumpets to give more space in front of them and I thought No1 would obstruct the air flow if any longer? Roger

Hello All I have made some progress today and some backwards steps First all fuel lines finished and double checked so I put 17lt of fuel in the tank(1/2 capacity according to the manual) So I powered the pump direct off the battery and just like you no leaks but the gauge was showing 2.5 bar so I adjusted the regulator to 3 bar. But then I thought is the gauge accurate so I fitted a second one in the line at front of injectors and powered up again and they both agreed but now showing 3.5 bar? So readjusted regulator back to 3 bar and started and stopped several times(regulator screw back to starting place?) I wonder if a small bit of debris got caught under valve seat?(I thought I had kept it all clean blowing through line before connection) But now I have a problem with the fuel gauge as it only reads 1/4 full ( spent a lot of time offering up to position and tweaking the arm as used to read low before) Now I wonder If fault the gauge it self? (I have an electronic regulator fitted? well a 10 volt regulator chip built into the original can! not paying £10 for a 50p component) So just the exhaust to refit and Lambda sensor wiring to finish off and will be ready with fingers crossed to try and start it. Roger

Hello All Been and collected my new spring today and it looks well made to me and ONLY £57.60 inc VAt This is the Company. http://www.gbsprings.co.uk/ They are UK made (Bridgnorth) I had an interesting talk with the Boss he used to work for Triumph in the later days and he seems to know all about springs Roger

Me to Roger

Hello Henry Just check the car well and carry what spares you can, anymore can be sent out next day. We always use booking dot com for all our digs as if you book carefully they can be cancelled up to 24 hours in advance so if you have to change plans it does not cost more than 1 nights accommodation. Please try and do a blog/report of the trip to encourage others to do more with their Triumphs! This what we cobbled together. http://forum.tssc.org.uk/index.php?/topic/1637-classic-le-mans-via-italy/ http://forum.tssc.org.uk/index.php?/topic/1833-trip-to-emerald-isle/ But most of all just enjoy it the worst that can happen is you come home on a truck(its not like climbing mountains or going to the poles etc) and the smile factor is GREAT Roger

Hello Clive This is interesting and confusing to me! http://www.pjmotorsports.com/velocity-stacks.html Roger

Hello Clive Like these? http://www.ebay.co.uk/itm/Dellorto-Weber-40-DHLA-DCOE-DCOM-full-radius-trumpet-velocity-stack-30-or-50mm-L/262119245060?_trksid=p2047675.c100005.m1851&_trkparms=aid%3D222007%26algo%3DSIC.MBE%26ao%3D2%26asc%3D40762%26meid%3D70a1b4062bf2419eb0c94e7e83c5f4b6%26pid%3D100005%26rk%3D1%26rkt%3D1%26sd%3D262114425349 Will they be worth the the extra £35 What are the dimensions of the K&N filter? Thank's Roger

Hello Clive The trumpets I need are 40mm bore and I was thinking of 25mm long which would leave 40mm to front face of the air box which from what I read is about right(same as choke diameter) In K&N filters I was thinking of perhaps this one http://www.knfilters.co.uk/search/product.aspx?prod=R-0990 But still thinking of making a box to hold a cheap modern car one? If I look for one that fits a 1600/2000cc engine should be big enough and cheap? Roger

Hello All Or how about these? http://www.ebay.co.uk/itm/2-x-RAMAIR-Carb-Sock-Air-Filters-Double-Trumpet-Weber-DCOE-Dellorto-DHLA-/271581092161?hash=item3f3b7e9941:g:uzYAAOSwA4dWGuxe Roger

Hello Clive I am thinking of fitting a set of these in the air box the 25mm ones http://www.ebay.co.uk/itm/Weber-DCOE-40mm-Velocity-Stack-Carb-Trumpet-IDF-Dellorto-DHLA-DRLA-Solex-ITB-/272400841050?var=&hash=item3f6c5af95a:m:mFWCgugmwx_eUSCzQCuYMiw Or how about some of this built into the air box? http://www.ebay.co.uk/itm/Ramair-Universal-Large-Foam-Pad-300-x-200-DIY-Make-your-own-air-filter-/351167961002?hash=item51c33dd7aa:g:hK8AAOSwRLZUEGEG I think I will stick with the 2 x 48mm i/d tubes for now as they fit nicely. I made a new engine breather today similar to the one on my TR2 engine I have yet to chamfer the end of the tube so the leading edge is longer. Roger

Hello All As some of you may know I am in the process of converting my Triumph Spitfire 1500 to EFI (Microsquirt) Well I have built an air box and have 2 x 48mm bore tubes coming out of it down to cold air. I was thinking what air filter to try and fit on the end and was looking a the usual K&M and I came across this article on the nissan site. http://www.nicoclub....oem-filter.html So now I will have a rethink and perhaps make a box to take a CHEAP paper filter? Roger ps how much filter surface area do I need for a 1500cc engine of say 100/120 bhp Or pehaps I can fit one inside the air box?

Hello All I have decided to get 4 of these the 25mm ones http://www.ebay.co.u...wx_eUSCzQCuYMiw They do 4 for £60 and seeing the aluminium would cost me £24 and a lot of machining plus the difficulty of get then all the same plus I would have to make a jig to hold them for machining! They will leave 40mm space in front which according to this site is right (ie the same as the choke size 40mm) http://www.nsxprime...._Sept._2006.pdf I am going to run 2 x 50mm hoses into the air box and try and fit a K&N on the other end! Roger

Hello Darren Another GOOD result I do not think I am going to bother with the IAC valve at this stage as my throttle bodies have the normal screws to hold the throttle plates open(in pairs) and a bleed screw on each body to balance them indvidualy with my carb balancer for any difference in suction(I think that will keep me quiet for a long time?) I have fitted the water pipe across the manifold and the air temperature sensor. I have ordered a few 8mm couplers so I can make a better job of the fuel lines (I think?) Its slow progress as I keep getting side tracked and changing things so it looks better(I think?) Still its a long time until march? Roger

Hello All A bit of progress today. Fuel and vacuum tube arrived so I have been working on these. I found the fuel line to be a VERY tight fit on the fuel rail(I don't think it would come off without clips?) I got carried away with the vacuum pipes and decided to make a manifold with 6 ports instead of having several tee pieces(see photos) which I thought will give a bit of a smoothing effect? It is a piece of aluminium tube 12.5mm o/d 7.25mm i/d x 350mm long I do not have any trumpets yet I was thinking of perhaps some of these? http://www.ebay.co.u...=STRK:MEBIDX:IT Or getting some aluminium and making something like this? http://www.ebay.co.u...r0AAOSw3YNXYS~A What do you think? Roger

Hello All Finished fitting the throttle body pull ff springs then started on the fuel lines. I removed the old one and was working out how to fit the new ones and decided I needed some pipe clips so I can do the job properly? So I ordered some of these. http://www.ebay.co.uk/itm/131817562225?_trksid=p2060353.m1438.l2649&var=431176153014&ssPageName=STRK%3AMEBIDX%3AIT So that has halted work on that( It does not take much to stop me on these COLD days) So I have made a front cover for the air box I have made. Then I was thinking about fitting the fuel tank sender(I have bought new seal and locking ring)and I do not wan't the new ring to finish up looking like the old one so I decided to make a tool to fit it. Still undecided on trumpets one the throttle intakes? Roger

Hello Darren A Historic Day? I have fitted the throttle bodies fully now and the heat shield(which I had to shorten by 2" as I could not reach the nuts on back?) I have also fitted the throttle linkage(just 2 pull of springs to finish fitting) I made up a fuel pump cable with plug to suit pump so just needs connecting to the relay/fuse/safety switch. I did not get around to fitting the exhaust or new fuel lines(tomorrow when snowed in?) not that I have to go out I don't do that WORK thing! Still waiting for the vacuum hose(they sent the wrong size but it will do for a fuel tank breather) and fuel hose still there is light at the end of the tunnel or a train coming. Roger

Hello Darren Is there any form of baffle behind the crankcase breather? I am going to do the same and I was thinking of blocking the rocker cover one off? The new exhaust manifold and inlet manifolds are now fitted and you can see the heat shield I am going to fit and the air box when finished? I think I will put the air temperature sensor in the air box? then in theory the ECU can adjust to suit the air temperature entering the engine! I have just ordered some of this hose, I thought about some nice shiny s/s type but I may finish altering things so this is a cheaper option and I know it is up to spec(not sure about some the stuff on offer?) http://www.ebay.co.uk/itm/251175712377 I think tomorrow I will refit the exhaust system and look into running the 2 new fuel lines under the car. Roger

Hello Dave The new gaskets arrived and all the holes are the same just a bridge across the centre exhaust port? so I assume they just make them all the same now but just remove the centre bridge from the 1500. Roger

Hello Darren The Tank is back in (bit of a fight!) but now I find the original feed is only 1/4"? so I will have to run 2 new lines in 8mm the fun goes on? I am happy with the tank mods I like to think a bit like a factory job? and the filter will just fit under the tank behind the the mills? board so nothing under the car. Roger

Hello All A bit more progress? The fuel tank is ready to refit at last! I have used Slosh sealant on the inside and galvanised and gloss black paint on the out side(It should not rot through in my life time) I have glued some black felt onto it since the photos. I have also mounted the fuel pressure regulator on baulkhead were the electic pump used to be. I have painted the inlet manifolds black to match the throttle bodies. Just waiting for the exhaust manifold gasket so I can fit the exhaust and inlet manifolds and a new seal for the tank gauge. Roger

Hello Dave O B******r ordered now I will see when they arrive if I can open up the holes with a flapper wheel? prehaps clamped between big washers or plates with holes in I have spent the day tipping tank sealer back and forth. Roger

Hello Paul Thank,s for the information I thought that were the same, I assume the centre bridge is missing on a 1500 manifold(I have never seen one mine came with a 4 branch) I have ordered 2 x 13/60 type it means the exhaust will sit better and should? pulse correctly(if I can notice any difference?) Roger

Hello All Will the 13/60 GEG648 gasket fit in place of the GEG681 1500 one? The reason I ask is the 4 branch manifold has the bridge between the ports and I would prefer the 13/60 type so the exhausts are working separately and better clamping of the gasket. http://www.angclassiccarparts.co.uk/home/triumph-5981/herald/engine/exhaust-manifold-gasket-herald-1360 http://www.angclassiccarparts.co.uk/home/triumph-5981/spitfire/engine/exhaust-manifold-gasket-spitfire-1500 They look the same spacing and manifold said it fitted 1300 and 1500 models so I assume it is the same?
