Little makeover for the '79

[Oneofthegreats]

Its all checked Tim. We dummy fitted to rods and pistons and on TDC, the pistons his goes just over the block deck. We still need to measure the TDC, but we will do that when we get more progress done in the engine.

Were not using 144mm rods, our rods are longer then 144mm but shorter then 159mm.

Well I'm very interested your engine spec!

Cause to go to 1.9L you only need a 83mm piston using the stock 1.8L crank & 144mm rod

If your pistons are too far out of the deck & the headgasket isn't thick enough, then its into the head quench & possibly valves! BANG!



Don't know of another rod inbetween 144mm (1.8L) & 159mm (2.0L) for the VW engine! Even then it would need custom pistons for the pin heights.

Had to go with longer rods cause of the pin position on the 2lt piston.

Pistons don't go over the deck that much....only a few mm. Ill have to get pic's once everything is put in.

Far enough.

Still doesn't make sense to me though.

Instead of having expensive custom(overkill) rods made, you could have got a much cheaper set of high quality 83mm (1870cc) or even 82.5mm (1847cc) pistons at nearly half the cost & not upsetting your rod/stroke ratio!

Horses for courses

Just be careful with pistons out of the block!

A few mm may not seem like much, but 3mm is 0.118" thou & a normal headgasket is only 0.040" thou. The piston will still knock on the head!

Dad doesn't like building his engines with stock rods. Number for reasons, weight, strength etc..
But the rods really aren't that expensive as you may see it, under 1k. We didn't go with the custom pistons because this engine was budget build and he didn't want to build his 16v itb motor on a 2L bottom end, so might aswell get the rods now and use them on the 8v as well.

Dad will explain to you everything in person next time you guys see each other. Its a little complicating over the net.

What i dont get it why not just throw in a 16v if your spending all that money.

Wouldnt a stock 2L 16v make just as much power as the 8v you're building or better yet slap on a trubo haha?

[jayjay]

i'm running a high comp 8v atm... they're silly motors to drive around in... 16v stock...? good bye 20vt mk2 scirocco..

Yeah we will man but this is just a experemental engine, and to have fun mean while.

Striped.

[16v_kid]

Bits and pieces...

Ground Control- Top strut Camber plates



Stress bars/sway bars



Bottom end nearly done, trigger disc also in.



Rear camber plates, -.5 degrees.


Pauter rods and pistons.


Stay tuned

[jayjay]

i think those bars up there are stress bars..? like for tying suspension towers and chassis stiffening.

looks good mate. sounds like it'll be good fun to drive

[16v_kid]

Thanks dude!

Yeah, they are stress bars, I just tend to call the sway bars.

[jayjay]

lolz. Should also stick a fat sway bar on the back.

what sort of 1.8 block are you using?

[Jarred]

madness. heaps of yummy parts there!

Cause we will have the rear bar for the harnesses, I think it will help with the stress on the rear end so no need for a rear bar. Good point but (:

The block is from my dads old GTI, short block 144mm.

[Spyda]

I think he was talking about the sway bar the goes along the rear axle. I would have thought a sway bar does more good than a stress brace on the rear?

Whats the benefit of the added negative camber on the rear?

Are you guna engineer and road register it? Should be prity zippy when its finaly done.
