cutting oil squirter reliefs in JE pistons - pictures

Post by **JDM_1990_S13** » Fri Jan 10, 2003 8:01 am

i have been posting this topic around nissan boards and getting feedback, just want to know if anyone has had to cut reliefs into forged pistons that they have ordered from JE or others. i got some JE's and they do not have the piston oil squirter reliefs on them, say some one talked about shimming hte squirter and then grinding it down a litttle carefully, can't really say till i look at them first hadn this weekend.. and guys in the uk have cut the pistons to resemble the OE ones and blanced them to get the weight of each the same again, any comments and those who have done either (both) how long has it been done and problems etc??

PICS >>

Awww mann!:( They screwed you, big time. After spending that type of money, you now have to spend more to have them modified. I asked my machinist once can this be done and he said that it can. It's just the way that JE one was design that has me skeptical because how close it is to the wrist pin. I've destroyed a set of wiseco slugs within 1000miles and toasted this set within 200 miles

Seems like you'll be cutting into the lowest portion of the skirt. I would send it back!

Post by **JDM_1990_S13** » Fri Jan 10, 2003 8:01 am

if i send them back am i going to have to pay for them to be cut or re-made? i hope not, i'll email them and see what they say.. are those above JE or the Wiseco?? and what caused the piston to break in those cases, detonation? or the piston actually hitting the squirters, or taking too much off the piston and weakening the piston around the wrist pin?

that looks scary? and what kind of boost were you running??

That picture I posted is what happen to CA18's with bad programming (Stock ECU remapped by ??T) and this was done at 22psi. I lost all 4 pistons during this event! Cleaned up the cylinders with an extremely light hone job and stuck in 4 used pistons with new rod bearings, stock pulsar headgasket, new headbolts, timing belt and camshaft seals. And would later get clocked by a state trooper doing 173mph in a 55mph zone while trying to see if it was actually a computer glitch that was causing my engine to that (it did not blow and I didn't go to jail).

LOL 173 in a 55 thats kewl. well once it is not in my neighbourhood.. i doubt they will take them back... you think they can be moved lower so they don't touch the piston, from what i am getting from others they have either cut them or shimmed the squirters far enough to just clear the piston.

any ideas??

if not i'll give them to my engine/builder/tuner who will be in orlando by a machine shop that can cut them to match the OE pistons and have them balanced as best possible, maybe get them coated in some kind of crazy thermal coating for better performance..

Post by **boost_boy** » Fri Jan 10, 2003 8:01 am

they can be cut, but man where the squirter is supposed to go is so close to that wrist pin area. It can be done, but they will definitely need the stock piston for proper measurement! Do not shim the squirter!

Post by **JDM_1990_S13** » Fri Jan 10, 2003 8:01 am

got ya, i'll give em all four new and all four OE pistons and let them do i right,

I have no squirters in my block, trade you some used but still sweet Todas for your JEs.

I had to cut mine, the CP pistons didn't have them either, but we have a nice mill here at the shop and a piston vise to hold the thing still while we cut them out. DO NOT mess around with trying to shim or bend the squirters, if the thing breaks you'll loose oil pressure to the rest of the motor and then bad things happen.

My advise is just take it to a machine shop and they'll do it for you, or you could send them down here and have us take care of them.

I'm surprised that a company like JE didn't make anti-detonation grooves on the pistons which would be the next section just above the top compression ring. Send them back, bro'.

Here's a pic of the head that's ported and polished!

Here's a pic of the strengthened rods!

Here's one of all 4 pistons!

So you only get the 8-port inlet CA shipped to the States then?

Post by **boost_boy** » Fri Jan 10, 2003 8:01 am

Yes! As far as I've seen, the CA16DE/18DE have the same port design even though the intake manifold crosses the valve cover. I've had the older model CA18DET with the multiple runner intake manifold, but decided I didn't want to play with that engine. What type of head do you guys get in the UK?

Post by **themadscientist** » Fri Jan 10, 2003 8:01 am

the U.S. head is the old small port S12 design, the S13 model is different. I assume the Euro guys get the later model head.

Post by **boost_boy** » Fri Jan 10, 2003 8:01 am

But wait a minute, this the head off my CA18DET which came out of the SSS attessa Bluebird. And definitely no CA18DET's are sold in the U.S. This puppy came to me via a freight container along with a bunch of other strange looking engines:)

Post by **themadscientist** » Fri Jan 10, 2003 8:01 am

that is most likely the newer design, did the intake go over the top or around the back of the head?

Post by **boost_boy** » Fri Jan 10, 2003 8:01 am

Went around the back of the head! It's the newer design because I've seen the older one.

Post by **themadscientist** » Fri Jan 10, 2003 8:01 am

yes it is.

We get the 4 port inlet head, same as South Africa

Post by **boost_boy** » Fri Jan 10, 2003 8:01 am

Sweet!!!!!! I take it there is three different heads for the CA18 series, then?

Post by **JDM_1990_S13** » Fri Jan 10, 2003 8:01 am

well i got the jap spec FWD SSS bluebird engine with a RWD gearbox and Jap Spec Secondary intake runners in the intake manifold. if that makes any sense at all...

Post by **JDM_1990_S13** » Fri Jan 10, 2003 8:01 am

don't think sending them back is an option really, they will not refund me and they will not exchange then i doubt..

i would have traded the JE's for the Toda if they were new sorry, but i'll send them off to a machine shop and see what they can so, with the amount of people that have drilled the reliefs in i'll give ti a try.

See you at the 400hp mark:ylsuper

i have just said screw it meng, i'm getting a Cam KIT instead of the RODS thinking of a TOMEI IN/EX 264 kit with 10 lift and solid lifters, just emailed them for a price, anyone have any other cam kits out there i should rhink of, maybe send crower a pari of cams and let them make something wild for me, anyone have any ideea of other good cam kits out there???

Post by **boost_boy** » Fri Jan 10, 2003 8:01 am

I got a pair of wild cams fo free from a guy I met online in malaysia. Cam specs are as follow: Intake 276* -0.438"lift and exhaust 268*-0.430"lift. He also gave me some racing maps for my SDS system which I thought was waaay too cool! Goes to show that there are some really cool people on the internet.

Post by **boost_boy** » Fri Jan 10, 2003 8:01 am

Be calso cool to find out the cost of the solid lifters as well. Let us know.............

Post by **JDM_1990_S13** » Fri Jan 10, 2003 8:01 am

yeah i spoke to JEZZ in the UK and he says he has the same kit but has not started the engine yet. but the solid lifters i think are needed for such long duration cams with such radical lift, are you using the stock hydraulic lifters with those cams??? and are they stock regrinds or custom billit ones??

i'll let you know for sure...
