Hey guys,

I'm in the middle of a pickle. I can buy a 4AGE 1.6 ltr 16 valve already in a sierra(BUT hasn't been run for over a year) for only $700ish (whole car as is).... But my mate has a G13b (swift gti) in his sierra and it fucking hauls arse. What is the way to go?? The 4AGE has everything set up in the car but isn't that flash of a conversion. But it's convincing as i need transfer case(it's a W/T T-case), jack shaft(to suit), tail shaft (near sheared mine from rear uni joint) and also a rear diff centre as mine has fucked pinion bearings and gears.......
Oh and I've got a coily 96".

Any thoughts???

[Ben_Sierra]

The G13b is terrible for an off road car.

What exactly do you wnat to do with this car?

[Joe]

If it was me i would keep it suzuki

[Ben_Sierra]

Definitely Joe, but not a G13B...

G16B is the go...

Still a suzuki

and the the rocker covers on them look cool too

Well his seems to go hard everywhere and never let him down. I have had a 1.3 carby in mine but need to up grade due to running 31's and just the plain fact I want more power. I want power/torque cause I plan to do many mods and turn into comp truck in the later future. But for now I just want to be able to have some decent reliable power/torque so I can enjoy tackling decent step hill climbs and bog holes.

[Joe]

Have you got transfer gears Zookzilla?

[ZookZilla96]

I haven't at the moment due to they don't make coily t-case reduction gears. That's why Im thinking the whole car cause it's a w/t and therefore can do reduction gears when I get the money.

[Ridge]

You wont be able to use the wt diff centre in a coily, the ratios are different.

If there are no problems with your motor, buy some transfer gears.

[steak_knife]

Do you know the model of the 4age??
I quite like the ole Tvis one's, $700 for the whole car's good, but you will then have to make it fit into your car..

[Ridge]

it is really easy to swap a leafy transfer in, all you have to do is swap the flange for the jack shaft from the coily case onto the wt case.

EDIT: all other drive shafts will bolt up.

[ZookZilla96]

Yer it's a Tvis model. Wouldn't really matter if I put both diff centers in my diffs, as they would be both the same ratios and wouldnt work against each other. Yer it is fully set up in another sierra already so the transfer across would be alot easier than if it where just the engine and gear box.

[Ridge]

The coily front diff can not be replaced with a wt or nt centre. The coilys have a high pinion front diff centre, to clear the tie rod which is behind the diff.
If you put in a leafy centre, you wont be able to connect your steering.

What you want for climbing crawling is as much torque as low in the revs as possible.

The G13B is a great little motor, and it does go hard, but its totally gutless at low revs and therefore not the best motor for what you are saying that you want to do...

Unless you gear the arse out of it. 5.12's and 6.5 T/C should be alright

bs mine has atleast 3x the down low pull of a g13a although not as much as a g16b but still more than enough to get the job done. i love mine

[Ben_Sierra]

A G13B has 112Nm of torque but that isn't until 5500 rpm.

A G13BA only has 100 buts its there around 3000rpm. I know which I'd prefer...

[jonno_racing]

have u ever driven a corectly geard gti powerd sierra? keep in mind gti is a easy bolt in conversion. also a g13b in a sierra will produce much more torque due to running the much heavyer sierra flywheel thats some thing most people dont take in to account.

thats right for off road use, 3000rpm is what you want but if your going to spend some buck son it turbo the G13b or do what i did with my gti

bored 1.4
sr20TB
4-2-1 headers (more for mid range power)
race port the head with some nice bd10 cams not to lumpy for off road but still makes a nice sound lol the down low torqu i had....... hecktic, i was killing my cuzins turbo gti that had 40hp more then me till 3rd gear

but i still think the vit 1.6 with the gti twin cam head is the best option, thats what im doing to my sierra

[ZookZilla96]

thanks for all the feed back guys. gunna have to really consider what im about to do as the engine, t-case, shafts and rear diff centre are all ready out and waiting for something to take its place. if anyone hear's of rear coily diff going for sale feel free to let me know as i would like that first so then i can atleast move it around (taking up room in workshop & also has mud from grill to tail gate!!) ill keep everything in mind and when it is complete ill be doing up a build thread so keep an eye out.

What kind of work shop, if your good with a welder & stuff, do the 4age ( royce will probably ban me fer saying that) I don't think you will regret the power of a Tvis 4age..

Gti has nothing on em, not even close.

ahhh fuck here we go again, an inert object is unable to create torque, otherwise we would all have solid rubber tyres and be doing 300km/hr

I dont want to be rude, but what a load of crap

A flywheel wont generate more torque, it simply stores energy.

power (W)= torque (Nm) x angular velocity (rad/s)

Torque is output from the motor.
Different motors produce different amounts of torque at different rev ranges due to a multitude of factors, i.e. cam shafts, compression, ignition timing, stroke, crank dimensions, etc.

The only way to gain more torque by bolting something onto the output, is to bolt on more gears.
(i.e. 6.5s and 5.12s etc)

[Fatzook]

Yeah I think what jonno was getting at was that the sierra flywheel has a greater roational mass, thus maintaining crank speed a little easier than a lighter flywheel would. This is helpful in situations such as climbing, or small rock steps, as it can sometimes mean the difference between rolling over an obsticle, or stalling.

Clear as mud?

FSck me dead. You've just listed all the things NOT to do to a sierra engine.
While all of the above might have been great in your front wheel drive ricer, they're totally unsuited to offroading.
60mm tb & db10's? Sure! If you want to shift your peak power/torque to 3000+ rpm higher into the rev range. How is this going to benefit a sierra?
G16 + twin cam head? Also a fail for a sierra. I've got one. And it's the worse performing sierra engine I've owned to date.
The dyno sheet says otherwise, but when it comes to driveability and useful power it's an epic failure.

thats fair enough, but while i was driving it, it just felt good and i just think if it was in my sierra it would be better then the stock g13ba the down low power i had, was sweet

if it is just your rear diff centre that needs to be replaced, look for a nt centre. they are a 3.9 ratio, same as the coilys.

[simonprice]

im with jonno my thing is fucking great off road
well the power has always been enough
but i am wacking a turbo on it
for more power

mine has enough with its gearing but you can never have enough.

[ZookZilla96]

hahaha im in a exhaust and mechnical workshop... I want to do the 4AGE conversion but there is some serious work involved.... although just got quoted for a G13B twin cam EFi for complete engine (computer, etc) $1800!!!!! thats cost price!! so im thinking this 4AGE is where im leaning at the moment....
