ask as many questions as you want mate don't worry about the search nazis....... i don't bother with it too much... i never have the time to search through the hundreds of pages of irrelevant findings...... if i can't find the subject i want on the first few pages, i ask... the search nazis can KMA People will either answer, and give you the feedback you are after, and it's fairly easy to ignore the endless "have you searched" posts..... or they won't......

as for a motorbike engine.... if you could get reverse gear... it could be fun!!!

Just to add to the bike engine thing ,

At one time i was looking at using a bike motor in crawler type buggy
and i believe you could build a reverse and foward box from a suzuki transfer case , by deleting one range and running a hi vo chain from the
input shaft to the output shaft in its place , when selecting high range you would run on the reverse chain , and low would be run on the original low range three gear set . = foward and reverse

Larry.

if you want to go motor bike try a honda gold wing motor they have reverse and are a v6 now i think

Nah go a Harley V-twin will sound cool!!!! Hav a zook put the bikies to shame

found a MK1 GOLF with a hyabussa engine

ok I want to ask a question!

are you just asking a curious question. or is it for a purpose. ie crawler, which challenge or just a fast a#$ 4by?

personally I like the sr20. strong, powerfull. reasonable price. and its a cult motor so you can get any amount of performance parts and find all types of motor builds for top end power or lower torque. and conversions into most smaller cars all detailed on the net.
there is also heaps of parts for converting into various cars. like cut down looms that just need power to run the motor.

the rotary is cool too!

enjoy

ps don't worry about grimbo. he doesn't realise how anoying search nazi's are.
the search function isnt the most accurate tool and atleast you did use it and you didn't find what you wanted so you asked a question. bravo.

it will be a dd as it's my only transport i have seen a lj 80 with a subaru motor in it went hard on an off road thats why i started this thread and it went pear shape for a while

Sounds good but he must of mounted it heaps high though , as they won't fit between the rails , and that sort of defeats the purpose of the flat design sub mtr.
(lower centre) imo.

mitsu 4g63 turbo swap!!

Im luvin that V-Twin always thought it'd be an awesome conversion into a zook Jus add some straight thru's and she'd be set to rumble. Plus they torquey to so not just for show pony's to sound good could actually be used 4wding

if your going to all that troube of having everything custom then why not a ej20? plenty of power, just make sure yuou got the gears to make it useable

i have thought of that with mine, i got a complete 12second cordia that i can use for parts if i want

what hd motor or aftermarket it will cost you from 5000 for a stuffed one or up to 20,000 starting price for a 2ltr vtech top fuel but hd's come in 79 88 110 120 or 200 pluse cubic inchs so it would to dear to fit one but it would be very cool

We sell revtech 110ci engine's @ work from time to time. At $15,000 AUD its a pricey mod.

but there nice and shiny and you can put two to gether and make a v4 with 220ci

You can buy a S&S Engine (similar to revtech and harley but higher performance) but they do a 145ci engine for about $17,000 a pop

the biggest v/twin was 2.8 ltrs it run nitro fuel and cost sixty thousand and 10ltrs lasted 1/4 mile now that would be a cool zook motor

I would suggest that bike engines aren't really viable, for a few reasons.

1) Cooling - even water cooled bikes have a lot of flow past air to keep them cool. Put one in an engine bay with a radiator full of mud in front of it and your gonna be in trouble.

2) torque - Whilst some bike engines have plenty of bottom end, it's easy to look like you have lots of torque when you have a 150kg bike and a 80kg rider to pull around. Off idle, most bikes won't do the goods in a 4WD with actual traction.

3)Gearbox adaption - this has been covered - $$$$$

4) Powerband - bikes develop massive HP/litre mostly because they don't have to be anything like as drivable off idle as a car motor. To approach bike output in hp/litre most N/A petrol motors need very clever camshaft/fuel control like Vtec

5)$$$ - $15K for a bike motor? Are you serious? I can buy a complete, new, fuel injected ZZ502 big block (502HP/700Nm) for $16.5K

6) Exhaust/airbox - to get the big numbers, bikes have very very carefully tuned carbs, exhausts and inlet tracts. thrying to get all this to work and flow properly at 15Km/h in low 1st is going to be a problem.

I'm sure this could all be overcome, but I think there are better options.

I have built sierras with G16B 16V motors (really sweet) G13BB Jimny, and 2X 660CC Turbos. I don't really consider them a conversion, but all of them were so much better than a stock 1.0 or 1.3 it wasn't funny.

SR20? Yes, it has (and can) be done, but in an effort for outcome balance, it's pretty hard to justify- it (and its gearbox) don't really want to fit into a sierra IMHO.

Steve.

Steve, How do you find torque production in the 660cc turbo? Are large amounts of revs required to drive it effectively offroad? I drive mainly rock (not mud) so am more curious about low rev performance.

Currently running a 4age which Im happy with so Im not seriously looking in to a conversion but if I was, this engine would be near the top of the possibility list.

I actually don't run a tacho with mine ATM - if it's making boost then it's making torque. If you run enough gears, they're grouse. The stock 5 speed has a 4.1:1 1st gear and with a 6:1 or more (such as 5.12 diffs) they are fantastic offroad even with big tyres. I am running 34's with TT 6:4 transfer and 4.1:1 1.0 diffs with 34 swampers and it runs fine offroad even when loaded for camping.

If your gearing was too tall, they won't be as forgiving as a 1.3 , but normally crawl gearing is easy to achieve in a sierra. the problem is too many revs at cruise, and they love to rev to thats fixed

They make about 85nm stock, which sounds crap, (100nm from a 1.3) but I am running a good dump pipe exhaust and intercooler so mine makes 12 psi up from 8 psi stock so I reckon I'm probably doing at least 100Nm. They start to boost at around 3000rpm.

They are a but doughy off boost but with no tach I don't really know- if it sounds like it labouring I just pull a lower gear and get on it. It doesn't lack torque or power IMHO, even on the highway - seems to run at least as well as a 1.3.

I am planning something like a starlet turbo with the wastegate welded up (I have an external wastegate to go on) as I would like more flow at the same boost so I have some headroom at cruise - ATM the turbo is out of flow at cruise speed. The stock turbos are too small for the application which is a legacy of the 47Kw 660 power limit.

The 6V (SOHC) sierra 660's are limited at 6500 RPM but the cappuccino version (DOHC) is limited @ 9200 rpm and is very useful for opening up the gears in a deeply geared car.

I like 'em. for me they are everything - EFI, wide powerband, they make funny noises, and they're weird.

Steve.

just like a harley

A harley with EFI and a wide powerband? Hmmm, I'd like to see that!

steve i near wet myself when i read you have a 660 in a sierra after the almighty carryings on you had at the mention of a gti conversion for all the same reasons

all new h/ds are fool ingeted that harley speak couse you speek funny after you ride a hog long enough enough the new ones come with efi and put out good kw nearly a 100 i think and enough torque to moove 1/2 a ton of full dresser and trailer at over 180kph not bad for what they are.boner

My dream is to run a 4agze in my stocker. I've told it's a very hard conversion. Which is what is really keeping me from going that route. I might just settle for the gti. Since it's mainly a bolt in conversion.

Thanks heaps for that Steve, I like the idea of small capacity turbo engines for some reason. I must be weird too.

Im not sure if its a harder conversion than a 4age. From memory (and keep in mind that I didnt convert mine) apart from the usual conversion stuff, you need to shorten the jackshaft and convert to a hydraulic clutch (hiace works well IIRC) and you're roses. A search will reveal more. Drew off this board has a twincharged GZE which is fawesome.

As has been discussed in other threads, I think a gze is probably too much power in a zook. Stock wheelbase and you will pretty much be weeelstanding on the street and driveability will go right out the window. This is anecdotal, I have no experience personally but still something to bear in mind. A 20v ge with some headwork, cams and zorst will deliver excellent, reliable power and remain driveable on and off road. I love the power of my 16v though but Im not that interested in kw in a froader anyway.
