What about the nissan cg13 micra motor.
I remember reading theyare about 55kg without accillaries. They are only about 100hp standard but being a nissan motor they are pretty restricted but they are tough as nails so would take a fair whack of boost on a standard short block. Would love to do a all out as light as possible race car with one of these motors. I reckon you could get a 1200 down to 650 kilos with one of them in it.

I have also looked into this,

You can buy specialised gearboxes for motorbike engines in the UK for about two grand, that just have forward and reverse in 1:1, and neutral. You then use the sequential shift motorbike engine. You can hook up two starter motor solenoids to the gear shifter and have two buttons on the steering wheel for near instantaneous gear changes. But my engineer wasn't too keen and I have to look into it for the CAMs rules.

Imagine the sound of a hayabusa engine in a 1K.

motorbike engine.... definately.
If ever there was a car destined for a bike engine, the b10 was it

The GTI car is ranked in the top ten most important modern cars of the century

who did they pay to get that ?

Well this is facts coming from 2 good friends. So before you go being a big shot and questioning my integrity i suggest you think before you speak. To add also they are only 2 engines it doesn't mean to let the baby out with the bath water on the whole idea.

I think you better get your facts straight as you sound the same as a rotary motor myth maker.

Every suzuki gti owner I know and have spoken to have taken their GTI motors the famous g13b to beyond 300,000klms with abuse for all its life and never complained about performance.
Ive had several with over 250,000 and they perform like high spec sports cars.

After market parts are available like you would not believe.
Gonzales in Puerto Rico has taken records for years in the FWD class with standard internals and 30-40psi boost and a local in QLD has taken a 1190cc version to almost 400hp for a slower ET but to illustrate the mighty G series potential.

Weight for a block and head is just on 60kg and 15kg more for ancillaries in the g16. Pikes peak was won many times with twin G series engined beasts also.

When I compared all the motors out there the G series is still being produced on the 1.6 Carry wagon, the sohc 16v head flows more than the twin cam g13b, they are used in light aircraft extensively, they have no VVT or other complex timing systems, they are all pressure die cast alloy and hardly ever blow head gaskets in with extreme boost with standard head gaskets and small and compact.

The only other engine that comes close but has vvt and virtually no performance parts available is the younger brother suzuki J20 from the vitara 2 liter.

A distant 3rd but Nissan/Renault is the Mr20DE followed by QR20de. These Nissan motors are taller but worth while pursuing for the all Nissan aspect. I particularly like the QR20De as it has so many aftermarket bits from Wolfe in the States.

I am going to fiddle with the GTI engine in my K, I have one lying around and you can buy sierra gearboxes for $200. Will let you know how it goes. You can guy cheap second hand go fast bits at redlinegti.com

Cheers!

Yeah got a 4AGE in a car sittin here Can sell ya the whole car if ya want. So you would have a front cut just need a RWD box etc for conversion.

I'm always loath to suggest non-nissan options but what about a 4AGE, they are cheep, light, compact and if you banged a set of 40mm webbers on the side they are super simple to set up... (Oh and are grunty little, rev happy motors)

Based on mates with swift GTI's they tend to go hard for about the first 5000k's then go down hill from there. Unless they were built with go fast bits i guess. Then we wouldn't be talking budget builds.
