66e 1000cc SJ Jap motor on eBay

[willycrumb]

Actually after looking more closly at them they look like CR500 cylinders. I thought all the 1300's were a one piece cylinder. These are clearly two separate cylinders. Does it say anything in the add...I cant see it.

ok, the couch rider needs to speak on this.....

up until i believe 05/06 the 1300's had valves

after that they did not have valves. so you both are correct

and to achieve the 1000cc displacement the cylinders are bore .010 over to achieve the increase in displacement.


66E and 66V/60U cylinders are interchangeable

although the 66E does have the more favorable port timing from the factory

thank you for the lesson in couchotomy :clown:

The older GP1300 cylinders have power valves and they will bolt right up to the 66e engine case.

nope the 66E/66V/60T cylinders were not mono cylinder but seperate cyliners

so no they are not cr500 cylinders

Here are some pictures of a GP1300 PV cylinder with the piston and you can compare them.

Yes you are correct, so you win the prize. :biggrin:

What is the diff in port timing on 66e vs 66v cylinders?

not specifically sure but i know if you were building a cheater ltd. 1200 boat, the 66E cylinders were an easy mod for some more power and unnoticed unless they looked at the casting on the cylinders

The GP800's were a bit more aggressive, from what I gather.

The 66e cylinders have an 81mm bore size and the 60T cylinders have an 84mm bore size and can be sleeved up too 90mm.

I was told that they are using Wiseco flat top pistons part number 7894M09000 but I've been unable to find them.

so whats this engine made for? Racing freestyle topspeed acceleration?

i heard the same thing.... i think they are a semi one off part #

I dug a little deeper
Crazy House is a Lamey dealer and part for Team Japan I knew this name rang a bell. Watch the videos in link 2 & 3. back flip with barrel roll.

66E / 66v can be bored to 90mm, I have done 86 & 87mm.

66E has more ports, yes they were the preferred cylinders for GPRs but they have gone back to 66v as they want the top end. 70mph +, there is an on going debate. PV’s or No PVS. Like us on the Lameys, Me I take PVS hands down as you get the best of both worlds sick bottom end, and good mid to top.

The reason RAMJET and I are interested in the pipe is as follows:

Stock 66E has 118-121 hp. I have dynode a few so this part I know is fact.
FFP has twin pipes that give 18 – 20 hp. 120 + 20 = 140 hp with just a pipe WOW!!!

The twin pipes suck for Blaster or SJ. Like the B pipe and PV’d lameys the head pipe gets in the way of the PV. If there was a pipe that has a head pipe like the GP760 FFP and a chamber like the LTD or MOD pipe that gave min base HP of 10 hp+ now you have a stock motor with just a pipe with 130 hp and as you add more that number jumps.
Waterdawg has a pipe, but well we all know about waterdawg!

I had this set up and Lamey dynode it at 148hp. FFP pipe, Gas Valves, 86mm cylinders, 150 psi, pump gas, stock carbs, stock elec, stock cases and crank and there was a lot more in her if you added total loss and a few other things. You get my point on the power you can get.

Me I would have 66E’s in all my boats if there was a good reliable single pipe for it, trust me I love my lameys but dollar for dollar for HP you would get a lot more.

66E’s have there issues, been there done that, but once cooled and the right combination of parts you can get a beast of a motor that runs.

EBAY add, those are 66E cylinders, you can tell by the mounting flats for the stock pipe by the carbs.

Now that’s my opinion, take it the way you like and keep on riding :biggthumpup:

are those numbers prices? If so theyre really cheap

 

[spence]

hey my dad goes over to china and japan alot maybe he could pick up some stuff is it alot cheaper? Would it be worth it?

why do that when you can get through vendors in this country....... if you know where to look you might be surprised at who can get this stuff

I was told that you can also use the Sea-Doo pistons part number 716M0900 and machine the tops down.

i think thats what people are doing. the seadoos already start with a bigger bore so the first and second over pistons would be the right size for those cylinders when machined down

Kool Thread!

wow I have alot ot learn about yami motors... that post by WB800 made my head spin... Is there a post or something I can read to clarify all the differnt motor types so I can understand what 66e, 62t, etc all means??
