FI - Forced Induction.

i think nispares.com.au has an L20 for sale, fully rebuilt for $750 or something.

or you could rebuild one to std specs with just some ACL pistons (or hyper-eutectics) and good moly rings and run about 5mL of neat molybdenum in the oil - that puts a thin (like 0.2thou) hardened coating on all moving parts to protect them under "duress" L series bottom ends are pretty tough things.

draw thru superchargers (like the good ol' SC14) work well and are cheap. draw thru factory turbos are prob a bit more again and then you could look to delco EFi and factory turbos and top end $$$ would be BB turbo, ext wastegate with aftermarket EFi. but it all depends who you know!

then it'll take all the pounding you can throw at it - if you're not stupid about it.

pro 240......why you say that the L18 is funner to drive than the L20B...please reply.. i want to know....send me a "pm"

I've found that in mild tune, the L20 is a much better street engine. noticably more torque, and more power at useable street rpm. It will be the faster of the two in 90% of situations on the street, and they're also nicer to drive under normal circumstances.

Yeh, guys the L series motors are brilliant, you would know after owning one.
I have an L series motr in my Skyline GTX, in my previous 280zx and 240z.

For a 1200, I would suggest putting on a hotted up A series motor, cause this would be less time consuming and cheaper.
However if you have time and money, go for a L series.
These motors, personally, I have found to be much more long lasting compared to an A12, if you drive it hard, and gearboxes can take a lot more beating.
Believe me, theres nothing like the sound of a L series grunt, especially with a turbo strapped on. MAJOR POWER.

Guys, no offense, but L series motor can definatly take a beating compared to A series motors.
Bigger is not necessarily better, but in this case, it is.

Although I love the L series, I wouldnt put one on my 1200, cause I wouldnt want to disturb the originality of my Datto much.
I love my Datto for what it is.
If I had to, I would go A14

Quote:Hmmm ... I drove one daily for a couple of years. Compared to the A-series it's harder to work on and noisier. For a street engine I don't see the advantage of L over A other than displacement. I would be surprised if the same size engine (e.g. L14 vs A14) is more powerful.

I got quotes put together for a rebuilt A14 ready for a supercharger to go into my 1200 coupe, and quotes to get a CA18DET conversion (or possibly an SR20DET)... So far the CA18DET is the cheaper option... Far cheaper option. This is possibly cause in North Queensland no one will work on the A series engines so I have to get things done by Nispares or Datrats.
But all in all, I know I will probably go for the newer engine, get the same horsepower, and save over $1000...

in NA form i'd agree, but when it comes to turbos, the L18 gets it hands down for me.

they just keep revving and the turbo adds all the torque you'll need!! so much fun...

A14/15 block, A15 crank lightened and balanced, 79mm pistons, nice port job on the head, lightened and balanced flywheel, good choice of cam, I think you'll be surprised, i was when i used to run one of these.

I find that to be incomprehensible. I don't doubt the truth of the statement, but the "A" series is based on neanderthal technology, while the CA18DET is much more complex by comparison.
Why won't they work on the "A" series? Do they have trouble comprehending the functioning principle of the pushrod & rocker?
