I’ve heard the 5k head has a better short turn radius in the port then any 4age head except maybe the famous 12,300rpm formula Atlantic head in the orange cars, what are your thoughts on this @kpr?

When is @kpr cooking up 5k VVTI?

209kg all-up including gearbox is very impressive. Doubly so considering the block is big enough to stretch to 3.5l at least. Some other combos I've seen (as in, actually seen pictures of them on scales so I can tell what's included or not).

Rover V8 3.5l carb and LT77: 221kg (not helped by 50kg gearbox, also not including headers as I haven't dug those out to weigh yet)

BMW N52 and GS637BZ: 218.6kg

BMW S54B32 and G420: 283kg

Mazda 13B Renesis and 6-sp: 204kg

Subaru FA20 and 6sp: 218kg

My honker of a Jaguar I6 and G290: 325kg

Also, could not be more accurate on the lack of garage space. Certainly feels like purgatory.

That's an awesome weight!

Goes to show how over weight the 3SGE Beams really is.

 

[Roman]

Yeah, just the difference from iron block to alloy I guess! 
This engine would be way lighter and more compact if it was designed from the start to be 2.5 litre. 
But, part of the reason it's good for this application is because its bodged down to 2500cc from a bigger design.

It's also amazing how much you can win or lose based on accessories as well. 
Like some of the engine brackets on factory engines are absolutely massive cast iron things!

[BiTurbo228]

An alloy block alone won't save you. That Jag AJ6 I have is all alloy. Though it would be truly gargantuan if it wasn't...

Very true on accessories. Plenty of 10kg alternators and power steering pumps out there, not to mention AC pumps. Gearboxes are another killer. The LT77 would probably weigh 10kg less if it had an alloy centre case, and 6-speeds are generally 5-10kg heavier than their 5sp counterparts. Flywheels are another major point of variance. Could be a nice little 8kg solid thing, or a 22kg dual mass.

Oh, is the starter included in your weight?

There is a lot of weight savings to be gained in this area, k20 water pump housing is 5kg which is insane, the engine mounts are equally heavy, definitely worth focusing on this area in the future if your trying to save weight $/time spent is well worth it for the gains.

ahem:

 

[Roman]

Ohhh this looks good hahaha

 

[h4nd]

Ah. piss.

[Roman]

Ahh so looks like where we are finally seeing the tipping point where he's pretty much rehashing same stuff and still without particularly convincing results.
Pretty sooky to turn off commenting only about an hour after a video drops. 
Not sure why anyone is going to hire him as a consultant when he's not really proven any results yet. 
He's not going to have any credibility until he gets that V12 sounding good.
Not constantly shifting goal posts onto other motors and setups.

EDIT: Yep, hes dreaming haha. wtf

[xsspeed]

I can't decide if he's trolling or not

[BiTurbo228]

$2000 a month for an exhaust that doesn't sound like the guy was intending it to?

Think I'll pass...

[Roman]

Almost as bad as saying a motor will do 10k rpm despite having no idea

At least you're not charging someone half their paycheck to show them how...before you've managed it yourself. That's a future business venture

$99/month - how to modify your block with a cordless drill

$1999/month - how to splooge together ITBs using a 3D printer and CF

I'll leave the production tier options up to you  

[Roman]

Third and most valuable option, is clearly drawing mspaint graphs for someones project 

[shrike]

So taking the daily down the strip or pushing the carina? I'm sure they'd let you push it down last run of the day

I'm glad cars are held to a safer standard but I do miss the days it was possible to get a wof sticker posted 

[BiTurbo228]

Well, that sounds like a saga and a half! Always the way when you're working to a tight deadline, though I must admit I haven't had the whole 'bitten by a cat I was trying to help' thing happen to me specifically...

Sounds good though. Sounds real good.

[HumberSS]

Well done on the efforts so far bro. Sometimes you gotta know when you're beat. If you want to feel good about yourself you can follow my progress. God I would love another AA63. One day. 

[Spencer]

Engine sounds like its on track to make good v6 noises which is great news. Cant wait for the Blog about this and instagram posts "He put a hilux engine in his Corona, you should rage post below about how your gay engine is better"
 

[Roman]

Has been a crappy month in terms of getting car stuff done.
Had the dog/cat/finger thing. (wow, that might sound bad out of context)
Garage has still needed work. 
Ended up away for work for about a week in South Island (Which was great! Just not good for getting car finished)
Then lingering flu bullshit that has been sapping my energy.
Not gonna lie it sucks big time to miss OS drags again.
But I guess I'm still on track towards the important part of the project (drawing graphs)
