awesome progress mate!! PICS!
i think i'd rather tig it, but both do really nice welds.... arrgghhh i want a TIG

Yeah tig is the ideal, but i don't currently have access to one outside of work. I've got a guy at work that will do it for me (one of the best welders in australia, dead set he could just about weld aluminium to steel!) when i can take it in..

Benny is looking at getting one so if he does i'll get dutto to do it for me. (Dutto works for benny full time now on the race cars and he's a welder by trade).

nice tips on welding will use on the weekend
what brand of rust converter are you using
and pics tooo!! x2

Its umm.. Motoguard? I think. Bonk (my mate that owns auto one here) gave it to me said it was good stuff.

Make sure you scuff it back with a wire brush where you are going to weld the panel.

[Preen59]

Oh i nearly forgot, with the brass bar, wear REALLY thick gloves. The damn things heat up so fast! Wouldn't want anyone blaming me for burning themselves...

[ontarv]

thanks will use gloves
wire brush ? hit with the sand blaster
yes i i'm lasy!!!!!!

[GoLfMan]

wear ARC welding gloves they are the best for heat insulation....

i love my TIG welding!

Yeah just the wire brush will be fine. Give it a good go to clean it up. Remember, if you're using the MIG, just a zap and then let it cool a few seconds. Depending on how the shape of the hole is, zap one spot, then zap the other side etc. If it gets too hot it will start to burn away and then you're in trouble trying to chase it. So if it starts to burn away, let it cool for a minute then go again.

Got my new rods! They're C.A.T. rods.

Here's a pic of one of them.



And here's a comparison pic between my new ones and a standard rod.



Very nice looking rods. So light! Dad said this arvo, oh a box has turned up for you.. don't think its your rods though, the box is too light.. Turns out it was. They have a very nice hone finish (haven't mic'd them up yet..) and have brass little end bushes, with 3 lubrication holes. I also got them with ARP L19 bolts. Very happy with my purchase for $290 US. They came from an (oh, you better believe it!) Ebay seller that calls themselves the "Crankshaft Depot". They sell a whole lot of 4 cylinder, 'sport compact car' etc bottom end performance parts.

Heh, it was actually cheaper for me to buy these new H beam rods than it was to get my standard rods re-sized, shot peened, crack tested and buy new ARP rod bolts... Crazy not to buy them really....

man they looks nice! your engine has so much trick stuff in it!!

[GoLfMan]

i swear if you dont get this ready for nats there will be some 8v hell to pay come hell or high water im having a ride when i come up, even if it is freddy flintstone powered

Dude... There's NO WAY it'll be ready for the nats. Even if i had all the money right now to buy and do everything, i couldn't get it done.

But don't worry, i think i'll take the old man's Karmann Ghia.. Its pretty hot. You'll be impressed. I'll take youse for a drive in that.

If you're coming up to syd inland, i guess you could take a detour to orange... it's about 3 hrs west of sydney. Come and have a look for yourself..

Its not that trick.. I just think that with anything, you should work out what you can afford and then do the best thing you can for that budget.

[Preen59]

Oh, i had to get a couple of valves back so a mate could borrow them to cut his seats in his 16v head, cause he got the same valves as me. So i took a pic of them..



Turns out they're actually supertech valves. Which i'm not happy about. Not because they're no good but because i could have saved a heap buying them from an ebay seller rather than TT.

[Preen59]

why are you bracing the foot well? extra stiffness or just thin floors?

Stiffness, my friend. It is the key.

[Oneofthegreats]

Bingo! Hit the nail on the head.

I may have missed it but, how much power are you shooting for?

There's some nice part's there matey.

Those rod's look very nice. H-Beam, good material, good lubrication, come's with good hardware. Fairly light too at just under 600grams.

Valves look good too. Undercut stem's, look like there swirl polished too!

This should be a really nice & strong engine.

You weighing & balancing everything eg. Balancer, crank, flywheel, clutch together?

Also measuring for actual compression ratio?

How much compression are you aiming for & what camshafts?

(P.S. I'm just asking cause I love engine work & modifying)

Ok, well i'd like to get over 200 at the flywheel, which should be achievable.

Yeah the rods are 450 grams total, and the L19 bolts should be more than enough. Usually the bolts break before the rods if you don't use good stuff..

Yes the exhaust valves are swirl ground and inconel.

Silky said with a 4 cyl you don't need to balance the crank with bob weights, so the crank will be balanced static (its going to be out by HEAPS after i knife edged it). I will be getting the rods balanced to within .1gm and the flywheel/clutch will be balanced, obviously. I'll be getting silky to organise all that because (as you would appear to have enough knowledge to know) an awesome engine that has been badly balanced can turn into a real heap real fast.


Oh, and i don't mind sharing, we aren't competing in the same racing class in which i need those extra couple of tenths over you.. (Ah, the ways you learn to keep secrets in kart racing...) Ask me anything and i'll answer honestly. Thats why i like this forum, everyone is eager to help eachother.
