This toyota rush thing is manual and north /south configuration.. maybe it's a daihatsu terios in drag?

I wonder if manual trans could be used in something else small bore toyota which was a bit less gutless in maybe a kp starlet or similar?

Yes, it is a Terios in drag.

The modern v8 motor of the moment in street car drag racing is the Ford Coyote DOHC v8. There has been lots of development from these guys racing them, but they spin them to 10k RPM and 3000hp on stock ford block and heads which is insane.

This guys car is pretty famous in the extreme/outlaw street classes (which are like 3/4 of the way to a pro-mod but steel bodies and street car bits like coolant and headlights). Older video but this thing has gone 6.20's, its amazing, it won like everything last year.

 

 

How many passes between rebuilds? 

Nuts for a stock block tho, I guess Displacement does help however.

Any idea what the bore and stroke is?

I'm surprised the M16A (Suzuki swift sport motor) hasn't had an honorable mention.. especially seeing as @kws has been in the thread
 

 

I thought that's what I had been in here for, whoops.

But yes they're a great engine, plentiful and I believe there are some RWD boxes that will bolt right up to them too

Jimny box should bolt up. Separate transfer box…..

Same box in the Carry van, with a proper tailshaft housing iirc. 

Note that Suzuki changed the gearbox in 2005, so now it has a direct 5th rather than an overdrive 5th.  Could still use it, but with a taller diff to compensate, just work backwards to get it to work with your tyres and performance desires (e.g. change a 3.9 diff to a 3.2 diff to get the same 14.2 overall ratio).

(Marina ratios for old school comparison)

Jimny has a proper tail shaft housing too as the transfer case is separate (like the SJ). The Carry gearbox (UK market anyway) has some wacky selection mechanisms, maybe for column change?  The 1:1 5th on the later ones is a bit of a pain as the usual reason for conversion on the British tat I’m usually working with is to get a taller top gear!

I come from a classic mini POV, but the under appreciated engine (I think) in that sphere is the Nissan CG13DE (1275cc).

It's understandable as it's factory numbers are uninspiring at 55KW / 73hp(flywheel), however for a mini conversion you need to fabricate both the inlet and exhaust manifolds, once you've done that it frees things up considerably (I got about 100hp @flywheel) with no other changes.

If you want to go further there are cams, ATB / LSD, and some rare rally bits like close ratio boxes out of the UK where they had a K11 Micra rally series. Unfortunately not much parts support outside the UK and Japan.

There's a bit of Nissan parts lego you can do as well, there's a CGA3DE which is much the same but longer stroke, the CG10DE is a 998, which has flat top pistons to raise the compression. Others have tried Corsa / Barina pistons or the larger bore CGA3DE pistons out to 73.5mm I think. They seem pretty happy to rev but I've stopped mine at 7,500.

Lots of boosted CGs been done, I think up to about 200hp but it seems 150 to 170hp is probably better for longevity.

Other options for the mini were: Toyota 4EFTE, Suzuki G13, Daihatsu CB70, and Honda B and K series and some Rover and Vauxhall Redtops in the UK. If you don't want to cut up the mini inner wings the CB70 and CG13DE are the only 2 car engines I've seen fit.

The donor vehicle cost me AU$500, a pretty awfully treated engine and gearbox to rebuild cost me $50.

So I was just thinking...

 

The M13 and K15 Jimnys still use a divorced transfercase

As such their manual gearboxes are essentially rwd gearboxes that bolt up to the M16/K14 Swift motors

Pretty sure the gearbag ratios on those are terrible from riding in @johnnyfives one
