you can make up a box like the mas one pretty easliy with some MDF, a modern stereo will fit through the old stereo slot, a small amount of filing might be needed but it should go in. i dont use the steel outer mounting case in mine. pull the passenger seat out and see if the AMP will fit, other than the firewall on the passenger side therent arent any real good mounting positions.

AHA! this is where your oil pump shaft should be at piston 1 TDC courtesy of: http://www.geocities.com/inlinestroker/

Have you tried adjusting the butterfly on the carb to get a constant idle? it might be fully closed with no throttle. if fuel is backfiring out through the carb then this could also be that your mixtures are too lean besides timing.

ill stick with my previous statementLOL and ya got me there mate, a "pot" of beer is a new one on me too.

for you aussies, on the new HPI ( high performance imports) volume 5 there is a 240z that ran a 10.18 in japan with a triple webber naturaly aspirated L28. Long live the L engine!

hmm maybe its my young age that steered me clear of this saying!

yeah they can be pretty loud. i have one feeding a surge tank for my EFI pump. if its similar to mine they are capable of 15PSI with good voltage. I wouldnt want to put any more pressure than this on your float bowls. i think the stock elec pump is around 6 PSI (correct me if im wrong guys?) and with 10.5 volts it will be a little lower than 15 anyway. the part that will let go if it does is the little valve in your float bowl that closes when the bowl is full. if it dies (and they are pretty cheap and easy to replace) your carbs will flood. did the pump come with rubber mounting blocks? you can use insulation on the pump to quiet it. mine hangs loose off the mounts so its not tight on the chassis, that helps too.

looks good to me, let us know how you go, and weather or not you blow the arse out of your float bowls from to much pressure. you should be ok though.

biker that must be a queensland thing. us new south welshmen have no idea what your talking about! SuDz, Come on to the forums again just before you leave, we'll see if we can get you on board a GTR for nighttime Sydney cruise

fair enough... does it have a PSi rating on the box?

actually i got it off the throttle body thread:D

what type of carter did you end up getting? oh and while those headers are sitting around off the car, you might consider getting them ceramic coated. it will help alot with underbonnet temps. check out www.240z.id.au he his done with a HPC coating up in QLD somewhere...

yeah i think you mean wollongong. its a bit under an hour south of the airport, 25 min from my place. theres 2 ways down there, the freeway or the old road which runs along the coast fill of twists and perfect for a nice datto. its a good uni, i have lots of mates there. how long you comin to oz for?

unbolt it, take it off and put a plate over it to cover the hole. then hook some new fuel hose up to your metal fuel lines. completely straight forward. you can leave it in there and just bypass it, but all it will do sitting there is add drag on your camshaft (the pump operates off a lobe on the front of the cam).

oh by the way if you go with the electric pump throw the mechanical one in the bin. it will end up being more of a hindrance than a helper. with the electric pump being able to flow better the mechanical pump will turn into a restriction in the line...

you gotta remember Gav, Datto-zed lives in townsville, its bloody hot up there, the heat soak that would be produced from a couple of minutes sitting in the sun would be intense. the mechanical L series Pump doesnt hold up well in really hot weather. your right though it probably isnt putting out enough PSI but i doubt even a new mechanical pump would be able to keep enough pressure to stop the problem especially with summer ciming up. another advantage of an electric pump is that you can turn it on before the car is stared, this will pump fuel through the lines and help purge them of vapour before the engine is started. datto-zed, if you go with an electric pump see if you can get the original electric pump bracket that is located in front of the fuel tank, this will make life easier with mounting. its up to you what pump you use, just make sure its a carby pump. you should be able to get one pretty cheap at a wrecker, i think a carter pump is a couple of hundred bucks.

if your getting up too 40 degree days then im suprised your vapour lock isnt worse. the more prssure you run through the lines the less problems you'll have with vapour lock. though never use an EFI pump with carbies, thats too much pressure. change to an electic pump, as 260zed stated try an RX7 pump off a carbureted car or by a new carter carby pump. also heat shielding your fuel lines that run through the engine bay to your carbs can help.

yeah i thought that would cause a problem too. walter fath built the engine originally with an e88 head and a spacer plate, when i changed to the P90 from memory the words F%$#*ng close were used here. but it all bolted together ok and runs fine. the head gasket is a standard thickness graphite gasket. ive been thinking about different slugs for a while whats the pin height and diameter on a VG30 piston? ill do a check on that piston/deck height again

the KA 24 e pistons is out of a Nissan Pintara 4 cylinder. the L 14 rods are out of a datsun 510 that had a 1400cc engine in it. very very rare. i tired to hunt down spares for my engine, searched australia, america and japan for them and couldnt find them. the L14 rod is longer than the L24 rod. not sure of the compression of this combo, check the engine calculator, though mine is about 10.2 to 1, both my block and pistons have been decked.

its an L28 crank with L 14 rods and KA24e pistons with a P90 head, combustion chamber 46cc. problem is the block has been decked so putting those specs in the engine calculator wont be accurate. i know for sure that my pistons clear the block im just not sure how much(from memory 2mm is what it was) this was visible when we rebuilt the engine.

just how far out of the deck is too far? im 99% sure my pistons clear the deck by 2mm...

i just finished doing this with good results except the injectors are in the manifold itself. check out my gallery. hey alan, do you have a link to a store in the uk that supplies the throttle position sensor? mine mounts off the throttle shaft behinf the webbers and im not totally happy with it.
