Billet 4G63 Blocks

[OEM]

Looks like someone is prototyping our blocks.

Welcome to Bullet Cylinder Heads - bullet products - bullet blocks

 

[tenn-gsx]

Interesting.

 

[viperlp01]

damn..... thats pretty sick

 

[hubz91talontsi]

I bet it comes with a hefty price tag, but boy do i want =P

 

[TurboDSM90]

It was just a matter of time. It will get harder to find parts for DSMs as time continues.

I wonder how close to pricing these will be compared to some of the ford blocks out there. You figure it would be easier to make a 4 cylinder block right?

 

[SOADweskey]

Ability to run different bell-housings huh, RWD Tremec 6-speed application anyone.

Exactly, I'm hoping for more company's to step up and produce some good quality parts to keep these cars on the road. These blocks would also provide better heat dissipation.

 

[t25fury]

only question is,are these for the dsms or the evos ?

 

[jrohner]

Unless they save a lot of weight, I don't see the point as the original blocks are good for basically any amount of power. How much would you spend to save a few more pounds? All CF body panels would be cheaper than that block.

Aluminium vs cast iron... Seriously...
Aluminium also has better heat dissipation properties.

Very interesting. Just don't see it as practical.

Yeah, it's definitely not. If I was going to spend big bucks for something, I'd have Coates build me a rotary valve head for my 4G63T, that would do more for me than this block would.

1. Sure alum is much lighter but the aluminum block will need to be beefier too. An all aluminum engine from a Saturn feels almost as light as just the 4g63 shortblock alone, but they are weak. Like I said, how much are you willing to spend to save weight? You better have all other possible weight saving things done first. The cost will make it pretty impractical, as it will cost more than an entire built shortblock (maybe even a whole longblock). People like Rau are still using the stock block so it's definitely strong enough; he listed a complete freshened engine (longblock) from his car for sale for like 5 grand or something.

2. Sure, but that's what the radiator is for. The underhood temps in many places are much higher than the water temp, so I don't see that being very beneficial. They're also designed for an electric water pump, which are quite expensive for one that may be good enough for anything that needs a good cooling system.


The blocks still need to be proven to be as strong or stronger than the stock block.

I would assume their initial testing (and primary focus) would be for Evo 4G63 blocks. I wouldn't hold my breath for the DSM community. Same reason a lot of the big name aftermarket companies are moving away from DSMs and towards EVOs & STis - just a newer generation of car to work with, rather than salvaging 15-20 year old vehicles just to try and save an old (and getting older) community.

Yeah, the Evo guys aren't as cheap @sses as we are. It would make more sense for them.

That saturn block is CAST aluminium.. Not billet.
Billet is much stronger than cast, as it's not porous.

Heat dissipation as in from COMBUSTION. Allowing you to run leaner safer than cast iron block. Seriously, this isn't that hard of a concept to grab. The 4b11 has better cooling than the 4g63, and is aluminium, which is why it can run leaner.

While I'm not disagreeing with you about weather or not it's worth it. But you can't compare a stock Saturn block to a block made from billet 6061 T-4 or T-6. T4 has a tensile strength of 30,000 psi. T-6 is even higher. The 4B11 has proven to be very strong, and thats just cast aluminum alloy. So I don't think these blocks are going to be weak. As for heat dissipation, a radiator can only do so much. If you can keep the block cooler you can keep cylinder temps cooler, which means you can theoretically go further before detonation.

But your totally right about price vs outcome. Not worth it for an average tuner. Or even a more serious tuner. Possibly a race team with unlimited cash could find a use for this.

But I would hope they'd put in cylinder sleeves and not use nicasil junk (that's the point of nicasil is head dissipation and that it's very hard, but it sucks having to have it redone when a piston goes -- both cost and extreme downtime).

 

[91stocker]

I also remember reading though that the 4b11 is only like 23lbs lighter then the 4g63. I imagine i could drop alot more then 23 lbs with the 5 or 6 grand this billet block is going to cost. But im willing to bet this billet block is for the hardcore guys and not the weekend warrior.

Yeah, it was something pathetic like that, yet the cars themselves are much heavier.

 

[JEFFREYCASTGSX]

Brent Rau ia about the only guy looking at these.

 

[91stocker]

yea the evo x is a heavy pig, i think its like 200lbs more then the camaro's. I have a 99ss weighs in at 3300 or something and the evo x is like 3585. That thing needs a diet.

 

[donniekak]

I bet he sticks with the iron. Not one nhra car under 7 seconds uses an aluminum block. Even the lsx guys switch to the iron truck blocks after so much power.

Well then these are a waste of money.

 

[Benshooter]

I know it's a whole different realm of engines but fwiw my dad and I built a 351 Ford SVO aluminum small block that was punched out and stroked to 455ci running on methanol for sand drags. It hasn't been dynoed but it runs high 3 second passes in the 100 yd track. We figured the engine was making at least 600hp on it's own and we had a 500hp shot direct port nitrous setup on it that he used for virtually every pass. The only thing that ever failed was a headgasket (14.5:1 comp). That motor has over 50 races on it now and it still going strong. At first it ran too cold and we had a hard time getting it up to operating temp so we started mixing nitromethane in with the methanol just to get a steady operating temp that was warm enough.

Or a 3kgt/Stealth 6 speed!! Not that anyone needing the strength of a block like this would be using it in a street car, but when I win the lottery, you better believe it haha
