The L16 can be sleeved to 88mm and stroked with the l18 or l120 crank for 1960 or almost 2100cc with 28mm pin height pistons and almost 1.75 stroke ratio. Also no pollution gear and lighter weight. Gearboxes everywhere for them and every other part.

Hey, good to here about the sr16ve getting transplanted into a different sort of car. Ive got one and im putting it in the front of a mini clubman so if you want any detail about anything just let me know.
Good luck with the conversion mate should be a weapon :)

Sorry to bring up this old thread but I thought I'd post up this link to show it can be done (well in a Silvia anyway!)

RWD SR20VE

A silvia is nothing compared to a little 1k.
Its like comparing Tatoo from Fantasy Island to Andre the Giant.
The SR series engines a very long and deep and will cause major structural work to fit in the 1k engine bay. The weight of the SR is Double the A series and will ruin its handling.
You have been warned and advised.
Mammi motors had a 1000 space frame powered by an fj20 with twin webers and although the car weighed just under 700kgs it understeered so much even with 150whp that they got rid of it. Too nose heavy with these engines. Also gearbox lever position ends up behind the driver. Sump will have to be Dry sump or change your whole front suspension and on and on.
You dont see any Lotus 7 or other kit cars with the SR for a good reason again weight.

Ive measured and planned for years what the best engine would be for the 1k and came up with...
no1. A15 turbo 105kg and 250hp possible.
CA18DE 118kgs easy 160hp (small and compact)
E15ET 350hp possible as in 11 second fwd drag road pulsars of late.

Non nissan...
ZDJK alloy 110kg peugeot 505 easy 200hp.
(Smallest 2.2 litre 5cm taller than a15 and 1cm longer with Renault fuego J6r waterpump) Also 12v head available with 36mm inlet valves.

13b Mazda Rotary 105kgs Na setup (steering box is a big issue as Im experiencing with the exhaust)

Scat or Brodex v4 3.4 litre with 360hp
Halve an alloy chev engine some available through speedway. around 90kgs dressed. Fully dressed gen 3 alloy chev v8 187kg and the latest mopar 148kgs. Latest magnesium blocks are now 30-40 percent lighter!!!

Rear mounted Hayabusa engine or with a prop shaft to the rear and use an Alfa diff/tranaxles but needs independant rear end setup. Will have 50/50 weight ratio.

Renault 17 Gordini (or renault alpine) alloy 4 cylinder hemi engine 80kg and 1.7 litres standard but easy 1.8 possible.

Suzuki g13bb or g16b 75kgs Baleno or cultus engines. 1.3 or 1.6 (with 1.5 and 1.8 respectively overbores) Turbo version make 300hp plus while NA around 220 possible.

Rover K series from latest MG and some other Rovers. Choice of kit car enthusiasts.
Roton engines has a rotary valve head for it now :)

Ford Zetec (latest cosworth type all alloy 105kg engine now growing strong among kit car bulders)

Hi D. Interesting list of engines. You've obviously put alot of thought into it.
What gearbox would you have used if you went with the G13B?
I noticed you didn't list the 4A-GE. Any reason for this?

Dont get me wrong the 4age is a great little engine (even with its small inlet valves) but it weighs more than a ca18 and just less than the better toyota 3sge and much more than the 2zzfe.
There are many great engines but weight is the biggest issue.
The suzuki engines always adapt to sierra boxes from 85-94 (g13a-bb engines) models which are short and compact with no transfer box attached.

One other engine is the latest Mazda 4 cylinders which are all alloy (pressure die cast not cheaper sand cast like the sr20) and come in the latest mx5, some mazda 3 and others. but I left this engine choice out due to its rarity and price.

The v4 is around 5 grand with methanol injection which sounds expensive but at over 300hp on straight gas and the cheapest high performance parts on the planet (chev) it would be the ultimate rod engine at 90kgs for the little datsun. Bolts up to any Borg warner and t5 or similar.
over 300hp + featherweight + sound of 2 harleys

I have an SR20DE at the shop and am planning to do a rear wheel drive conversion on it also. Ultimately it will become a SR16VE but at this point I am just working through the mounting and adapting a bellhousing for the rear wheel drive conversion. I will measure the dimensions of the distributor tomorrow and post the results as I believe it will be very similar to the SR16VE.

The bellhousing that I am making is a FWD SE-R bell housing and I am modifying it to accept a Toyota 5 spd. transmission.

Will ultimately be installed in a rear drive tube-frame SE-R b13. For now I am working on a 1200 to go in the car, as I have all of the parts and will get it up and running before the big motor gets installed.

okaaay ... we don't like to discourage old school noobs, but this is sounding a teenage fantasy

in any case, consider the compact ga16de, fwd only, but they do have a jdm rwd version

was there a rwd ga16de?
Do you know what vehicle they came in?
They are awesome little engines and i think they would be a perfect engine swap for a 1200 for the people not wanting to go turbo/big engine route.
Quite light too i suspect.

ga16de same weight as the ca18de.

The Fiat twin cam Rigolo uses on many cars is pollution free, accepts the later 16v big valve lancia head, weighs less than an Sr20, is stronger, more compact and produces over 800hp with halve the cost that goes into an sr20de.
Even pushrod 3tc engines in puerto rico outdo sr20de in every area with only 2 valves and 3 valves in the 3tg for over 800hp also.
The sr is overrated and massively oversize.
Even the Ka24de pumps out more in Na with and without little mods.

The sr16 and 20 in a 1k is just a waste.
the 1k with an a10 has almost 65 percent weight at the front and with an sr forget it.
Even an old kinswood will overtake you on the corners.

In a drift sylvia, 180sx or similar no problems as drifting doesnt need power to weight.
