anyone built one ?

[flaxton]

a high compression 1lt zook engine and if so how did u do it and what kinda carbie did u run ? ... and i no plenty of people are gunna say y bother and dont bother and blah blah negative nancie stuff but in the end my engine needs a rebuild and i it does what i wanna do with it and its fucked so even just a rebuilt would be good but i was thinkin abit more compression would b good ... i could go to 1.3 but its my daily and i dont want it off the road for to long


if anyone has so positive input thanks if ur gunna b negative dont bother posting thanks

[mrRocky]

i know a guy who goes to india and races for 3 months of the year, he says they get a heap more power out of the 1ltr and are on an even par with the 1.3's. I assume shaving the head for a bit more compression and a carby rebuild or swap would make a fair bit of difference. If you dont mind spending some $$$ you could get some decent lightweight pistons possibly custom made (venolia, cp pistons) maybe lighten the flywheel
but in some cars it pays to leave it how it is. Generally as long as you dont use weaker components and upgrade with forged or hypernetic pistons any reduction in weight to the reciprocating assembly of the engine will result in a gain, and you can spin them to a bit higher rpm.

i`d like to build up a 1l myslf one day, but i got a get through my list of 1.3l first

Occasionally (read once every year) 1.5mm oversize 1l pistons show up on ebay, that might be the path to compression.

Otherwise get a spare head and see how much meat you can take off it and find a MILD cam to complement it

I`m kind of convinced that if get some small cv carbs off a bike and spend a lot of time tuning rather than `bolt-it-in` you get some nice power and fuel econmy

Ultimately rebuilding it for a small supercharger may be the only thing that is a single item change that will give you significant power jump

Its a path that not many people take, and those who do probably go down the 60`s-70`s techniques of `flow da head,big cam, special carb and big exhaust!`

[flaxton]

Thanks for the positive feed back guys I will have a chat to the boys at the head shop about it this arvo

[v840]

Have you thought of going in the other direction and lowering compression and adding forced air induction?

1lt turbs or thupercharged would be killer.

[dank]

Yeah you'll show those those 660cc turbo drivers what real power is! Go for it man, anything is possible, whatever you do...lots of pics lots of video

[Santos]

.... but most of all with new territory 'measure 10 times and cut once' , not the other way round!

Enthusiasm gets the better of most people trying something different.

[flaxton]

yeah a turbo 1lt would b sick but im not a fan of suck through or blow through so it would have to b injected and and that would b a masive job i do have a series 5 rx 7 turbo and a micro tec so i could just do a 1.6 turbo or a swift turbo engine ... i would like to keep it carbie i dunno a smallish side draft webber might work with high compression at least i can ajust the fuel mixtures not like the awsome zuk carb with no ajustment ... but yeah thanks for all the encoragment i just need to get onto the boys at the head and engine shop and c what they reacon about it maybe some of those oversized pistons would b the go

Get a K10A import motor

Factory turbo, injected and all alloy motor

74kw @ 6450rpm
132 Nm @ 3000rpm

Suzuki K10A Turbo
One of the latest breed of high-performance micro engines is the Suzuki K10A Turbo.

The K10A is a 1-litre four-cylinder that’s fitted with a DOHC, 4-valve-per-cylinder head. The K10A also boasts variable inlet cam timing and an 8.4:1 static compression ratio to maintain driveability when the little turbo is caught off boost. Maximum output is 74kW at 6500 rpm and there’s 122Nm at 3000 rpm – more than all right for a 1 litre engine! The K10A Turbo can be found in the 1997 Japanese Suzuki Wagon R and is available with a choice of a manual or automatic transmissions.

Bob says the K10A is becoming plentiful in Japan and, at present, you’ll pay AUD$2650 for an engine package with loom, sensors and ECU. Interestingly, Bob says this engine is popular with hobbyist aircraft and hovercraft builders due to its light weight, torque and top-end power potential. He also points out that it’d be a trick conversion into a local Suzuki Wagon R or an old Mini. Again, there are no known problems associated with this engine.

[flaxton]

Wow that sounds very interesting indeed do u have a web site add u got that info from I wonder if it would mate up to the enginemounts in the one liter but for 2600 I could probly build a turbo git engine coz I got a ecu and turbo already but still it would b cool turbo 1lt

[Gwagensteve]

Jock have you actually seen the K10A motor?

I can't think of a harder motor to put in a sierra. They are custom made for the wagon R so the motor is VERY tall - the inlet manifold is right over the top of the rocker cover etc.

It would be a very hard motor to work with. Good numbers though. We've looked into it but the K6A is a better option for fitment into a sierra.

Bit small of a pic but Gwanu is right about the height but everything is possible.

http://autospeed.com/cms/A_2643/article.html is the web address that was quoted from

Other option are as Gwanu says.

K6A all alloy twin cam 12 valve 3 cyl injected turbo intercooled engine
Name: K6A DOHC Turbo
Type: 658cc EFI DOHC 12-valve 3-cyl turbo
Power: 47kW @ 6500
Torque: 103Nm @ 3500
Sources: 96-97 Alto RS/Z

F6A alloy head 3 cyl injected turbo intercooled engine

Name: F6A Turbo
Type: 657cc EFI OHC 6-valve 3-cyl turbo
Power: 43kW @ 5500 (90-91), 45.5kW (92), 47kW (95-on)
Torque: 86Nm @ 3500 (90-91), 87Nm (92), 98Nm (95-on)

OR

Name: F6A DOHC Turbo

Torque: 85.3Nm @ 4000
Sources: 1994 Cappuccino, 91-93 Alto Works RS/R (4WD east-west), 92-93 Autozam AZ-1 (mid mounted)

Or even better but EXTREMELY RARE is the
F6B engine

657 cc efi dohc 16 valve 4cyl turbo intercooled

Screamer of an engine but I gave up trying to find one and settled on a cheapy F6A SOHC half cut for $1200

Just search the forums and you will see some good build ups of peoples cars ( here and elsewhere). If you get a sierra half cut (F6A) you can drop the lot in in one solid weekend of work. Just slot the motor and box in and change the wiring harness



Or you can just do a search for info on the SC100 suzuki. It was a small car (thats where the SC comes from) that suzuki built but gave it a upgraded engine. Higher compression, bigger carb and here are the engine specs

Engine: 47 bhp at 5,000 rpm; 62lb/ft torque at 2,800 rpm.


You can get this from your engine and even more if you want, just keep researchin, don't look fo rthe easy fix and never forget how fantastic your Suzuki really is :-)

[flaxton]

it all sounds like good ideas but if im gunna go that far i might as well just go a GTI 1.3 and tubro it and use my microtec or i could build a 13b turbo rotary engine for it but then i would b back were i was with my rx7 in a big money pit and breaking things all the time ..... but i will keep lookin at a high compression or oversized pistons i just need to find a suitable carbie for it

[Gwagensteve]

Jock - 100% that's not a K10A Turbo - the airbox is connected directly to the inlet manifold.

Here's the pick I have of the WagonR K10A, Non turbo:



It"s pretty hard to make out but basically the inlet manifold and in this case, the airbox is on top of the rocker cover. That's the BACK of the motor in this shot.

Wagon R's have very very shallow and very tall engine bays. As a result, they have made the engine as narrow but as tall as possible. I had another photo, but I can't find it. In the photo I had, the thing looked so tall you'd need a pro stock bonnet scoop to get one in a sierra. ( I exaggerate, but you get the idea)

We did a lot of research into these when they popped up as an option.

From memory they have a 660 bolt pattern, so you need a 660 gearbox to make them work. Not easy to come by, or very strong. Did I mention they are hard to come by?

There are NO afermarket parts for these motors, even in japan - they were on sale in the Wagon R for about 25 minutes on one Tuesday afternoon.

Seriously, they're a terrible idea.

There's a large performance culture for the 660 motors though, and they're basically a bolt in. They are also a bazilliontyfive times better motor than any sort of new school F10A.

I actually quite like the old 1.0 - they are tough (probably tougher than the 1.3) and simple, but they are way past it now. There's no way I'd try to make power with one. It's going to be a case of diminishing returns, mostly because of the 1.0 gearbox- the small clutch, tall first gear and no overdrive means if you loose bottom end or gain much torque the car's going to be a pain.

Just my 2C.

I have a 1 lt with quad carbs of a road bike on it in my LJ 50 goes like a dog shot up the ass it also has a muffler of a road bike the motor is full house for a 1ltr head ported, custom cam, raised comp,extractors etc.
Will get some photos for you

[Gwagensteve]

I'd race you for pinks with my F6A *joking*

Sounds cool, and I bet it sounds cool, I just don't think I'd spend the money on one. My F6A owes me $1200 and came with a 3.6:1 first + 5th gearbox and a whole donor car.

I have boost and EFI.

Steve.

[rustys]

I only payed $350 for the LJ and the motor was in.

Yes it sounds sweat and the more you rev it the sweater it sounds but efi would be good on side angles.
Note the road bike muffles on it to


Garth

[Gwagensteve]

bear in mind too an lj50 with 31's on it doesn't need anywhere near the torque of a LWB sierra loaded for camping on 34's on the highway.

Steve.

[rustys]

If he was after torque I would use a big block and then fit some 54s not 34s.

Doing up a 1L seems like a lot of work and hassle for very little gain.

From a quick search - 1L has 34kw. and 1.3 has 47kw.

So just by doing a 1.3 conversion you gain 40% power increase (hows my maths?) Now how much work do you have to do to get 40% increase in 1L's power. Im guessing more than a 1.3 conversion?

Modify a 1L and you will still have old ladies overtaking you with motorised carts.
