Thats some nice power figures! Is the same power achievable with a bored out L16?

Hi rezlo if you could maybe change the su's for weber sides ishky (if thats how you spell it) makes a range of cams for the L motor with nice double valve springs and retainers. One of the guys I know here in cpt had a L20 that made 128kw with 270nm on the wheels with 40sides a billet 306 deg cam crane springs in a w53 head the sub was all local parts with no arp stuff all datsun. He says the best motor he has built for a oval track car made 147kw on the wheels

Rezlo I'm sitting here with the Motorsports catalog: There are Flat Tops (10-1?)for L18 12010-P8612 is the .040 set, Arias (12-1 I think) 9996-D1067B. Camshafts were the SSS Cam .434 Lift/248 duration and Rally Cam 475 lift with 290 duration. Heads listed are Comp 11041-V9182 and SSS head 11041-U0600A. Turbo rod bolts with 13 stamped on them 6 short 11056-P7600 4 long 11059-P7600 with washers 11058-21001. Valves listed in 42mm 43mm 44mm Intake / 33mm 35mm exhaust........the larger intake sizes needing optional seats. SSS distributor is listed as D409-54K

I'm "told" that a SSS motor with lightly ported head was 140hp-ish but there are guys on here running L18's and they'd know better than I would. I'd go with the SSS Cam if it doesn't already have it, extractors port job for a start.............that should make it go decently well

Im lokking into dropping an L18 into my 160U, keep up the thread!

what casting is on the head? next to NISSAN? W53? A87? etc and does it have a W after the engine number, i thought it should be a violet in SA?

Hi Rezlo my brother is in Jozi and has a PG720 with a bone stock fuel injected L28.This motor came in what we here in Zim know as the Skyline GTX.He is running the motor with it's stock box but the diff is a stock PG720 item.As far as pistons go if my memory serves me well he used Ford pistons for his rebuild not sure exactly which ones though.I could give you his number if you would like to talk to him.Oh and that PG720 of his goes like stink.

Rezlo on the cam side of things. Do not go to mad with the SU's especially if you are going to run something as thin as ATF oil in them. Currently I'm running a 268, nice bottom down torque, but would like to go one or even to steps up, but that will be the limit.

In a previous A12 motor my brother ran a serious wild cam with a set of SU's, this resulted in the pistons jumping up and down and tunning was a nightmare on ATF, he had to revert to normal 20W50 car oil to keep the pistons from jumping.

The L18 responds nicely to all the usual mods,like more compression, webers & extractors, good spark, balancing, bigger camshafts, etc. Talk to some people here in Australia like Stewart Wilkins & Arther Jackson at Stewart Wilkins Rallying, Baz at Datsports, & if you sign on to the Brindabella Motor sport Club (a large rally based club in Canberra) there's somebody by the last name of Munyard on the NSW Central Coast who is their L series God.
You should be able use the 4.11:1 diff ratio from a Bakkie (h165) in this car. The brakes are the same as B310 Sunny's so any S13 disc & rotor conversions should work the same. The biggest problem might be finding a strong enough gearbox, as I've broken a stock Stanza 5 speed behind a stock L18, & I don't know if you could get any of the larger 5 speeds in South Africa. If you can, you might have to enlargen/move the hole for the gearstick.

those were called Stanza in aust with L16 and different grill and headlight, and were successful factory rally. sort out the ride height for the best handling for what u use it for. no point rattling your fillings out just to ride on the bumpstops for the look.

ya thanks for that ozdat tip.
