[nosh1t]

g'day everyone i'm ryan and this is my 620

 

plans there are no plans

only plan is to get it done

AT ALL COSTS!!!

 

list

body droped with shock floor and shock engine on 20 inch black chrome rims.

roof chop and round tail lights and a custom dash and gear stick

tilting/lifting bed with weld in tailgate every thing fench or shaved

and custom cnc grill with retgal head lamps

and thats all i can think to list for now

heres the photos like all good builds

the start

started to shave in some spare time

checking out hilux buck seats with some taller friends (roof chop)

time to cut the crap and get in to it

some parts for the notch came

got it down to bare metal

tacking stuff in and checking it as you do

4 set up and tacked in

making smoother for a better finsh (was plasma cut)

notch cover

still working on this should round the ends and insides of it

and thats where my fuel tank will get moutned later

and a joke me my old man folling around lookslike where slumming it

had to make space so moved it out side

 

thats where its at rite now i have started on the front end and still working one the brakets and fab work like upper bag mounts and rear cross member

man that things got some crazy pinion angle goin on. you might recheck that before you weld it all up.

 

other than that it looks badarse!! i like them 'notches'!

[LeDevil]

Welcome aboard nice progress what rims are those?

[Greiggy]

lookin good brother...

[nosh1t]

yeah famerjoe pinion angle had to google it haha

its set up rite the 4 link and the yok and there 20 inch rims so it is what it is all i can change is the driveling and crossmember which is in bad shape anyway

 

anyideas as to what could fix that

[Bob3]

NICE! Keep the pictures comming. :thumbsup:

[datsun dreamer]

Looks Good:cool:! And I've said it once and I'll say it again....You Aussies have all the goodies(Wing Windows on doors and right hand drives:D!)!!!! Cant wait to see more Pics:cool:!

[Pacific coast Datsun]

Believe it or not a drive shaft U-joint that is on an angle does not turn at a steady speed. If you imagine looking down inside the driveshaft tube at the bent U-joint, you will see that it spins in an elipse or oval. It speeds up and slows down as it turns and because it is mechanically connected to the engine mass which tries to turns at a steady rate, there is vibration. As far as driveshafts go, less angle is better, however with any angle, vibration can be reduced by having two U-joints arranged at each end so that the acceleration/decelerations will mostly cancel each other out.

 

Obviously the two U-joint angles must be the same or equal for this to work. The angle at the transmission to the drive shaft must equal the drive shaft to the differential. As shown below:

In the case of a two piece drive shaft the same applies. Treat each half as a separate drive shaft. Input must equal output.

 

BTW BEEBANI gave me the tutorial on this. I only hope I remembered it correctly.

SWEET. Definitly keep the pictures coming.

Liking the round notches & good progress! Was wondering..whats the P next to the license plate?

 

in australia we have a licencing system where you are on a provisional licence for 3 years - during that time there is a power to weight ratio limit on cars, and also total ban on driving performance cars ( turbo/supercharge or V8)

More fun rules and regulations we have, yay

[peanut2425]

lookin good, is there going to be enough clearance for the 20's up front?

how far are you going to body drop it?

looks like you got a L series engine and some disk brakes on there already and bag on bars I see, good choice and looks like a cracker of a work space and I see 4 grinders in 1 pic, why on earth do you need 4?

When are you planning on having finished by?

[nosh1t]

finsh date hmmm

 

wel 4 grinders one im a carpenter so two are work grinders

and the other 2 was a deal at a magnamart shop in ablino park rail its like bunnis

and it was when i broke a work grinder

 

20 inch rims will be fine in the rear

 

and pushing it in the from

boday droped to the rocker and not like how you done it peanut because i will need the inch half or what eva it was you cut off

 

i'll be running a 30 by 30 4 mm wall on the ground and weld that on the back of the rocker and make the tub line up

 

far as the from gose have to z notch the front of the frame 85mm (2 and half inchs rought translation) or maby 2 inchs if im lucky with the changes im going to do to the bottem control arm

 

done nuthing to day but check measure ments and figure out the front end and the pinnio angle issue (where i fucked up)

 

layin have to make the cross member go up 35 mm (inch and a half)

genrall ride hight

 

ryan.

[cheg]

thos stands are top of the line haha You're truck looks ausome keep up the good work and what kind of rims are thos?

[nosh1t]

g'day ratsun

 

well i got rite back in to it today and hit it slow

with out any steel suppers opened and no 4mm plate to make a notch for my front end.

-----------------

motorivation plus

-----------------

and i all so had the time burn my hand a+ for enought because i burn it good got two fingers and my thom is white

i work on as any one would do

 

so i got some new toys

measure up before un bolting the bottem control arm

mark a center line and square that up and cut it off making it esayer to make template

so then i cut the bottem control mounting patten out

flat dics (grind off bers) till smooth

and got it ready to be used as a template for making the blot holes out

clean it up ready for welding and marking out

marked it out like so

plasma cut it out, cleaned it up and marked the mounting holes out

looking good

clean

its not finshed but its enought to bolt it back on so i did

there we go

and i took the engine out because im going to have to z the front of the frame tomorrow

 

ryan.

thanks for reading and comments

[Figbuck]

Noice!

 

We need to come up with a rating system for cool or hipness. Like crossed rat-wrenches or something.

 

Brotha Ryan here is working on four crossed wrenches so far.

 

:thumbsup::thumbsup::thumbsup::thumbsup:

[paradoxx]

congtrats, thats a pretty nice work, well done! I demand more pics pics pics pics!! XD

[impala_631]

looking great!!!keep it up

[nosh1t]

demanding more picture i could put some up of my famaily at christmas time ?

joking

 

im going to go work on it now

all the picture from now will be of body work because i have ran out of steel

[peanut2425]

Why do you need to do a z? Is it just because the top ball joints are binding? If so you can just pie cut your upper control arms.

[airedout]

Cool, its always good to see another bagged datsun. You may want to look into lowering your drive shaft hoop with the upper links mounted on it. Your geometry would be much more correct a good bit lower, right now it looks like you have no instant center at all. Just my 2 pennies.

 

coming along nicely, keep up the good work!!!

[hacked521]

wow, looking good. deffinately digging the progess of your work. The notches in the back flow with the frame pretty good, wish I would have done that on mine a little better.

 

like airedout said about your driveshaft hoop, lowering it could help your geometry out alot. Other than that, it looks really good. Nice welds too, looks like you got alot of heat into them.

[nosh1t]

lol thanks peanuts yes that is why i had to z the frame and pitty i have oready done so

 

but main reason is that im using 20 insh wheels and they will have no camber at ride hight

 

and i still need to do what you said and make a custom upper arm but i will do that when i can get some steel

 

with the rear end i see no problem with the 4 link set up or the hoop

so not sure

 

thanks anyway

ryan.
