Can someone catch me up on Sprock 300 kits and cool heads?

[Hoosier_Daddy]

I hear he will still make 300 cylinders but isn't making the cool heads any more. But I'm just wondering, is the 300 cylinder just a sleeved stock cylinder? And what is it about the cool heads that make them so much better? I'm just curious.

[fabiodriven]

I was just on the horn with him today- He can still have the heads made and the whole mod with you sending him a cylender is either 6 or 650 bucks, I can't remember which he said, but at least you'll have a ballpark figure.

I've never owned a coll head myself, but just by design and the name I'm led to beleive they dissipate more heat, not to mention they look trick!

[scooterroo]

heads are billet, with interchangeable domes for different compression setups. beleive there is three different size domes to choose from. being billet aluminum, yes they disapte heat alot more efficiently.

Hope you dont mind if i jump in here but this sprock racing thing is somehting i just learned about with the Jimmy White race. What is so great about these sprock engines. I am not a two stroke know it all so forgive my stupidity but what would be the difference between something like this and an ESR big bore kit? I am looking to get a two stroke really soon. Gathering ideas.

Thanks!
Jim

Maybe those guys can fill you in. If I'm remembering correctly Sprock focuses on Tecates only. I might be wrong.

[DeePa]

He made a 330 tri-z kit as well clutch baskets, intakes, the list goes on...

Sprock has been turning out the aftermarket parts for the tri-z since there is little aftermarket support. He makes the only cool heads, big bore, clutch baskets, ect for the Z. Plus him and the mosh's went out of their way to make it possible to have maier reproduce a full set of plastics. Billet clutch cover is the next in the works i believe. Sprock makes some amazing stuff

ESR Does NOT Compare to ANYTHING that Sprock can do.... ESR takes a Cyl. "From PRO-X" that TDR,CT,TRINTY,etc "for the ATC-TRX" Motor's and bead blast them ... sell's them ( telling you that it is Ported ) and since that is 72MM BIGGER .. it "feel's FASTER"!.. BUT IN FACT ..................
IT IS NOT !!! .............
Cory does the T-3's .. TRI-Z Stuff .... i think i'm close ? CORY-Moshman ...
CHIME IN PLEEEZZZZZZZZZZZZ

[scooterroo]

cory = tritecate350 not moshman. sprock offers probably the only big bore kit for the t3's, well at least that i know of.

[Hoosier_Daddy]

Tri Z stuff too? cool

Well, right now you can pre-order the 310 tri-z kits with or without the billet head. with the head and dome-$600. without the head- $450. Here's a link, http://www.planettrike.com/showthread.php?p=2452#post2452. And yes, the big bore is a stock cylinder that has been resleeved with the larger, ported sleeve. then everything is match ported and ready to run. The "cool head" is an all billet head, wich as others have said, dissapates heat much more efficiently because it can flow more coolant across a larger surface area. Also you can change the domes out to run premium pump gas, 100 octaine, or full race fuel. I recently installed one of his heads and intake, and it did make a HUGE difference in performance and much cooler running temps. I can't say enough good about his products and support. Get ahold of him, hes a great guy to deal with!

This OLDIE can do some nasty work with engines too. Gotta give the bling king some credit shens

[Mosh]

Hey Ronnie! Nice to see you around again.

A little history lesson here for you new folks.
Ronnie was doing some awesome stuff for the Z's and other machines,and had the baddest/fastest Z on the planet till he sold it.HE had spent years researching Z stuff and motor mods,and is one bitchin designer/fabricator,Engine guru.Etc....

A company other than Sprock did make 300 kits for the T-3.I dont recall thier names,and I doubt they still make them.
Klemm Research made a handfull of bigbore Z engines back in the day.

I met Garageboy on the boards when I first joined and built my first Z..

I said "ya know? Coolheads would be cool for the Z"

The next thing I know Sprock calls me out of the blue"You want a coolhead for a Z ?" I was like hell ya!.That began our Z craze of aftermarket parts.
Next thing I know,he was like "Bigbore kits,Intake kits",I said clutch baskets,he was like Yeah Yeah......
Now it has grown into a full blown aftermarket parts support for the Z.All the way down to custom plastics.And some other items on the burner.....



Sprock likes to make things no one else does.
Everyone makes R stuff.The T-3 and Z guys had NOTHING,as far as big bores and the like.Actually,Sprock had been making T-3 stuff for a long time,but back when I joined the boards,there wasnt much T-3 support for his products.The trikes were there,but I dont think but maybe one or two guys had one of his T-3/T-4 300 kits.

It is becuase of him we have these things.Thank you.
I Have been pounding on My 330Z for almost 2 years now.I had the very first big bore Z,and well all the parts he made,and built the bike you see below.
I have ridden his 86 T-3 300 kit,and it hauls the mail too,and has been hammered on for over 2 years with no issues.

Unfourtanetly,I dont talk to Sprock that much these days.
We just have too much going on.I have since sold 2 out of 3 of my Z's.
I am glad I got the stuff when I did.And I want to say thanks one more time to Corey And Ronnie for doing everything they did for me.

I only need one more part.One of them Aluminum long thingy's.:naughty:

My z runs real stout.

Here it is

Here are vids of last year on the "test cylinder".Since then,I have made some changes,and it is alot faster than last year,but I have not been able to get any time slips or new vids.

[Hoosier_Daddy]

Thatks for all the info. It really helps.

Another question.

Can I get an intake and cool head for my stock bore cylinder?

[cheaptecate]

Great wright up. Thanks for all the info and prices. These kits are a lot cheaper than I thought.

[scooterroo]

i believe the cool heads come for the stock bore, as well as the bigbore cylinders. he used to have a nice site up, but i believe its down now.

[scooterroo]

i have been thinking of doing the bigbore with cool head for sometime, maybe santa will be nice to me, yeah right!!!! watch out chris, i think theres gonna be some other t-300's coming for your title of "fastest t3 on earth".

[Tri-Z 250]

I'd like to mention that the big bore kit requires a coolhead. Spock is running pre-orders for round 2 production is sometime in the fall. As I was told the Z-Coolheads are still available(stock,stock high compression, big bore dome inserts). I'm sure as they sell out and the kits start selling out more will be made. If your thinking of getting a kit...Save your money by looking for spent JUGs for a Z. I'm sure Corey would take any and if you have one that needs to be sleeved perfect. Dude the price is straight up KILLER! I have an old add from Trinity and he charged more back in the day with no cool head. I saw today a guy mention an Ohllin's motor kit...being from across the pond I'd say it's possible because the close realationship they have with Yamaha. I like to see them beat the $. The trickest part is the Clutch basket....buy now, son because he has the ONLY type available and in the future these will all be gold!

[userj8670]

Wow, reading all this really makes me want a tecate and z. I will prob end up with an R though as the parts for a tecate and z are alot more expensive and harder to come by. Not to mention money is a little tight. I dont favor one over the other, just which ever is cheap ;) Thanks for all the input!!

[MTS]

Ill just put my 2 cents in, For anyone else to take there Z jug to a machine shop and have done the work cory dose would be 1200-1500$ with parts and labour, it is a KILLER deal, :beer

[cr480r]

I have never understood where all the hype about cool heads comes from.. all the added coolant volume does is add weight IMO... But maybe thats only because I have never seen proof of a HP gain... I prefer the sleeper appearance of stock

[Mosh]

Well the best benefit for the Z guys,Is the savings of 26 bucks for a head gasket when you have to open up the motor.
The O-rings are re-useable.
As far as temps,I saw a 10-15 degree drop on my stock 250Z motor with his coolhead.What wieght???Are you kidding? 10 ounces more of coolant?That isnt even measureable,not to mention,the coolhead for the Z weighs maybe 10 oz more than Stock.

Then the whole intake kit he designed,drops the whole 2 lb boost bottle set-up on the Z.So I will call it a wash.You can't even buy a stock head for a Z anymore.The benefits are endless.........
Without these coolheads for the Z and T-3,machining a stock head to accomodate a larger bigbore piston would be risky,and expensive.

[MTS]

So iv herd older big bore Z's had cooling problem,s with there punny stock Heads, where 90% of the heat is made Imo, the cooler it runs the more power it makes to a point.

[clutchcargo]

I agree with Mosh, you can't beat the benefits of the cool head. Plus, the Z's tend to run a lil hot, so any added cooling is good.
