true true...so a blown a15 would be fine?....also is efi a waste of time and big dollars?

I found my A15 could blow off V8s from the lights keep up with all the latest NA jap stuff, and really provided all the performance you needed in a 40 year old chassis designed for 1/3 the HP.

It was a quick car and always kept my pulse racing.

You can overpower a chassis, (a Datsun ute aint a Porsche) there is a fine line between high performance and a deathtrap.

nar ur made a very good point....i also think wen it comes time to sell it a worked a15 would be more appeling to people as it is half original and realiable...money isnt a issue....so any ideas where to send my motor (jts?)...take into account i live in a small country town so sydneys bout as far as it will go!...i was thinking bore out,balanced
& blueprinted,ca18 raditor,electroic dizzy,flat tops,cam and then later on dcoe 40mm's...i dun wana get the wbbers till the motors pretty much fully done coz ill get brand new ones and thats where all the money will go

personally, if i had the funds to fund a ca18 install i would rather concerntrate it into a wild a15.
I think a lot of people underestimate the fun that can be had in an a15 1200.
Light and powerful is where its at.
Even an a15/14 with 140hp would be a blast to drive on the road.
The ca isnt the heaviest engine in the world but it adds up. Engine, gearbox, bigger diff, much larger brakes, etc in weight.
Have you ever compared a ca and an a series gearbox? huge difference.

Im alittle cross minded as i wouldnt mind a sweet ca in a 1200 but i think for the price and effort an a series is where i'd end up.
And if you want a turbo, a series turbo setups have proven themselves before as a solid power producer.

Of course this is all just my opinion and its your decison on what you want.

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

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.

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

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.

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

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.
