sweet...is ther any difference? lyk quailty....i want 2 twin 42mm webbs

so you want a mean A15! well your in for some Competition! why? because i've got the same idea! in me new 1500 ute, i'm going to build her up for my first ute! I'm don't know yet what is going in it but looking at a stock looking custom. twin 42.... now where did I see them.... ebay I think about 3weeks back. there is some around.... somewhere.

1500 utes have j15s in them

as for carbys, webbers are easier to get all the tuning bits for and are thought to be the highest quality ones.....the genuine webbers anyway

Weber originated the sidedraught dual throat carb with the DCOE. Dell'Orto improved Weber's basic design with their DHLAs. Weber have adapted the Dell'Orto design improvements into their DCOM series.

Go for Solexes on a road car, they have a vacuum port so you will at least get some fuel economy.

Webers and Dellortos both have their ups and downs, if you get the 2lt alfa dellortos you will have trouble getting them tuned at 1/3 throttle as they have a lot of progresion holes meaning a rich mixture and leaning it out by running smaller idles can cause significant engine damage. You'll have trouble finding a proper pair of universal dellortos. Parts are plentiful through an Alfa bloke on ebay, I have bought kits and jets through him before.

Ive never seen a 42 dellorto.

I have 42 webers on the racecar and they are perfect for a worked L16. I dont think you'll need to go to 42's for an A-series donk, the money you would have to throw at the thing to make 42's work will not be worth it and not streetable what so ever, trust me race engines belong on the track not on the road, they like to rev and not idle, you'll be going through plugs all the time. Get some new 40's, nice cam and clean up the ports freshen head, rebuild the bottom end and get it dyno'd with someone who actaully knows webers and you'll be set.

will you aint gota chance of catching me haha u will be suprised at wots under the skin of my tidy little ute....the cops nelly coulda put my ute off the road but one off the cops here raced a trp car and once i said i got all the paper work they all of a suddern went quite if you wana ride in a FAST dato ute pop in to mine this w.e n ill take ya for a spin...thanks whitesedan...ill keep the post saved for future reference...the ute goes lyk a petrol dipped snake but i am a 'want more hp' person...keep the ideas cuming

You could save your money and adapt a daihatsu Applause HD 1.6. It won 3 Australian rallye championship series in the 2ltr and under class for 3 years in the early 90s. Bare engine is 62kgs (all pressure die cast alloy) and complete around 80kgs. Adapt a Feroza bellhousing to a Celica t50 or other 5 speed and run some quad motorbike carbs from an R1 at 40mm each. Have them tuned to suit one of the many available rallye spec camshafts available from MRT for this motor and expect 150-160hp and 9000rpm with stock bottom end. This engine is famous in rallye circles due to its abundant mid range torque and endless redline. It has a SOHC 16v head very overall compact design and there was a factory version called Detomaso with 125hp using mild rallye camshaft, tuned stainless steel exhaust. Its weighs halve of any Ca18 and 25kgs less than an A15. You wont need any head work as the 16 valves are the size of hondas famous ZC or d16 16v engine with same combustion chamber design yet larger bores possible if needed.
Imagine with just custom sump, bellhousing and engine mounts you can have 125hp from factory or for under 3k or 150-160hp using a low km jap import HD for $8/900 and the rest in cams, exhaust and adapting to your choice of gearbox. The dizzy clears the firewall easily on the 1200 using feroza dissy and cap etc. Run no computer just straight LPG.

sounds mad but i wana keep her original....since i am on my p's i was thinkin of buying a ca18det and working it off its nuts then wen i am half way through my green p's put her in...good idea? or second option send my a15 to jts and get them to work it...prob is if i dont put a ca18 in it ill lose interest and wana sell me ute for something else....help plz

original??? how is converting to ca18 original?
Original as in factory, i think not. Original as in no ones done it before, i think not.
Work that a15 sucker, you know you want to.

well original as in staying with the same make...nissan....not sum mungral breed.....so u think the a15 would be the wiser option?
