Looks and sounds grouse! Indeed sad to hear that it got ruined!

What did that cost you to build? If you made 106hp with an A12 surely an A14/A15 could make more with the same money which I can only assume was more than $5k???

Here is my old A12 that I sold for $3500.00 freshly rebuilt, most the specs are in the description. I sold it for peanuts to who I thought was going to be a long term good friend, certainly wasn't the case.

Sunny Truck worked A12

At her most reliable best she made 106hp at the wheels in full race head outfit and big induction. Street I ran her with tighter induction and smaller port head to get some low rpm power. Great motor, the owner destroyed it in six months, brought it back to me to inspect. A sad day indeed.

I've been known to be a bit of a bargain hunter and because it won't be a rushed project, I don't mind waiting for the right deal to come up.

If 150hp isn't streetable, what is the limit where I would be starting to push it?

It really depends on your purchases too, if you don't do your research and you're not hungry for a bargain your budget can quickly dwindle after just a few transactions.

Avoid the expensive eBay items but keep an eye out for misspelt and poorly advertised goodies. Some people spell Weber as Webber. You'd be surprised how many auctions are poorly advertised and thus sold for cheap.

For carburettors Mikuni and dellorto are much cheaper and arguably superior in several aspects.

I've seen that setup on eBay already. Not bad but I wanted to go L16 Block with L20B Crank and different pistons. Would be fun but a lot more headache with fitting etc. New trans tunnel, gearbox, probably stronger diff, heavier suspension and brakes. Wiring and electrical. Not to mention engineering.

I thought 150hp would be achieveable for that money based on the old posts of read but I guess today's dollars don't go as far as they used to. What are the specs of a $5k built 100hp motor. Can anybody give me full specs of a 140-150hp A14/A15?

$5000.00 will possibly, possibly, possibly get you close to the 100hp mark in a naturally aspirated outfit. It will certainly get you over the 115hp mark as a forced induction setup with cash to spare.

In NA form I reckon for every 10hp over 100hp you would need 1500 to 2000. People gradually build their motors, it makes the costs a little more acceptable but at the end of the day the costs are pretty shocking.

Swap done wheels and grab clysons efi manifold. A nice efi a14 should net you over 100HP with Cam. Pm bige he will point you right direction. But a series and 150hp don't make for reliability from my reading.

gearbox options will be limiting factors as you need to find a 60a or 63 series gearbox suitable for a series.

better option but for $1300 there's a lz combo on Ebay in Geelong. I've never been sold on.the lz personally. L series good enough in a 1200

G'day guys,

I have a '76 1200 Ute which was my late Grandfathers. Currently stock A12

I have always wanted Injected Turbo Datto and had settled for an LZ Hybrid setup.

After doing a bit of research into what would be required for such a setup and the costs involved I began reconsidering. I've also been pondering as of late and I pictured my Grandfather and what he would say to me if I went this way. He was a funny Maltese bloke with a thick accent and although what I imagined would have been extremely funny, I'd have to agree. He absolutely loved this Ute and it was the last thing he ever worked on and it holds extreme sentimental value to me.

I've now began considering keeping it an A-series for the above mentioned reasons as well as various other pros being Easier to convert/swap, cheaper and more available overall, more original and nostalgic, lighter and more within my capabilities.

The only reason I've dismissed it in the past was because I was never sure if I would be happy with the end result i.e. power and limitations. After doing a bit of reading and scouring the forums, there are some A-series putting out some decent numbers and times.

I've set myself a budget of $5,000 for now. I will not require any labour to assemble or fit the engine as I plan this to be a Father-son project (My dad is a qualified mechanic and flat out petrol head...however he's knowledge of Datsun's is not the best). Any labour will purely be machine work etc.

The car will be 95% street car which will be driven predominately on the weekends but I would like it reliable enough to be driven daily. So strength and longevity are important to me as well as power. As it's mainly going to be a Sunday car, I'd like it to be slightly on the angry/rough side not entirely streetableif that makes sense.

The engine will be built on a stand as funds permit over time and so if I have to stretch this budget a little, I don't mind to much but I've started at $5k as a ball park.

I'm thinking for now to keep it NA for simplicity and see how I go. The $5,000 must include everything ready to fit and turn key minus the drivetrain from gearbox back. I'm aiming for 150hp + if possible. Is this achievable or am I way off?

I've done a bit of searching around the site but can't seem to find complete combinations and direct results.

I've read a few A14 V A15 threads. It seems people’s opinions are consistent in that A14's like to rev harder than A15's and have a more smooth power band through the range however the A15 has more torque due to the longer stroke.

Any help or advice is much appreciated.

Cheers, Joe.
