I love getting suprised, but not sure like this.

[Robert90sx]

To make a long story short. The motor set that I purchased thus far has the following parts on it.

First found the nice twin plate OS Gilken clutch set up alread installed as well as a pretty nice oil cooler set up. Thought it was odd to see, but then figured that maybe it was common in Japan.

Then found out that the injectors in it where 550cc rx7 injectors. So this motor had to have been pushing more than stock power.Figured then I would pull off the intake manifold and clean it up because I have a set of stock injectors coming. To my suprise I just found out that the secondary butterflies where removed . The manifold was port matched to the ported head .

I know that the valve covers have been removed and put back on at some point. This makes me think about what other **** has been done to this motor. I need to get this puppy running soon, but now want to pull the head and inspect the pistons.

At this point I am affraid of what I have. I have cranked the motor and sounds nice, but I am still worried. What kind of abuse has this motor seen. Screw Nagasaki Motors.

I might get some pictures of this if time allows.

I would be happy if I was you, those are some nice parts to have and there may be more. I'd definitely inspect it well but even if you had to pick up another block you're probably money ahead.

Let me see if I have this straight. You have a motor that has been fully built likely to the tune of several thousand dollars, you have over a $1000 hanging off the back of it in that twin plate and you say screw the vendor? That doesn't make a whole lot of sense to me. You did screw them, the parts and work you have identified so far alone are worth more than you probably paid for it. Would you have been happier with a tired clogged up unopened motor that needed a rebuild immediately?

[Robert90sx]

When I got the motor the turbo was gone, and there was no wiring harness. My thought was that there was a nice turbo on it that was pulled off. I then had to fight with them that got me $200 back and told to find the parts myself. I did get screwed by the vender.

The parts are great. And in the long run I am very lucky. My problem is that I am going to have a kid soon and really was hoping to be able to get this done soon. I have had this motorset since last March(took a long time to get a wiring harness), and need the extra set of wheels.

Now I have to wonder if the motor was found in a junkyard dead from a fried piston ring, or something else. I just need reliable for now.

[themadscientist]

Reliable= leave the KA in it.

If you are still short parts let me know, I will see what I can source for you.

[sjbsuperman1425]

so..you are having a kid soon, and you are trying to swap a motor? i would've put it on hold if i were you...although my family is pretty poor, but then again, im a selfish a$shole who LOVES my car hehe

btw, not having the Turbo gives you a GOOD excuse to get a better one. i'd be happy if i were you. although im happy right here with my extremely good condition unopened motor

[Robert90sx]

This project started before my wife was prego. So that was when I didnt need 2 cars, since then of corse its now more of a issue.

I have a new turbo already. Rebuilt and balanaced by a good shop.

[Bwana]

Hey, if you want to swap for a stock CA setup I have one setting in my shop. Pretty sure the owner would be happy to swap with you...

[float_6969]

LOL, you don't have a short block lying around there too do you? Maybe one without a crank or pistons or rods? I kinda want one.

[themadscientist]

It won't fit remember?

[float_6969]

LOL, no this is for a different project.

[DALAZ_68]

makes me wonder if its worth the trip to Vegas for a

LOL, you don't have a short block lying around there too do you? Maybe one without a crank or pistons or rods? I kinda want one.

clean block and head...300 bucks...?

[Robert90sx]

repost.

[RM12577]

cant beat having two cars just in case, I currently have 2 cars and a motorcycle, but my spare car smokes like crazy and i just lost a wheel on it the other day, the bike is leaking oil and the turbo is out on my CA.... so when all of them decide to break at once its not a good thing, still able to drive the CA but its throwing clouds of smoke every time i sit for more than a minute idling at a stoplight.... and the bike runs but just drips oil out of every place it can.... but hey you might have had some major issues with the swap coming in without the turbo and everything but at least there was compensation in expensive work and parts on the motor, and hope you can find the cash to get it all set up even with the new addition to the family

[Robert90sx]

I thought I would give this a little update.

I finally got everything put together. Time to start it. I never pulled the head or valve covers hoping for the best. I cranked her over and the motor tried to fire, actually spun over a few times, but sounded like my timing was way off. I figured I would take a look at the timing belt to insure that it has not slipped off a tooth. To see my self looking at this.



Who makes these? There are no adjusting marks, and don't know what to think.

After looking at the cam, it looks brand new and would love to figure out if this is after market as well. Any identifiable marks on it I can look for?

HKS is the only company that stamp their trademark on the camshaft itself. Look at the transmission side of the camshaft for numbers. If there are some, let us know what they are and we may be able to help you determine what you have one way or another. As for the cam gears, those are old school HKS units. You may want to check the compression before you go any further because when engines have add-ons like that, they've been raped and sometimes over-boosted which will lead to cracked ring lands and/or all types of other issues. Other than that, good buy .

ok so if your gonna sit here and b**** and whineabout upgraded parts for FREE, ill email you my address, id liek to trade your clutch, intake manifold and head, cams and camgears.

[ca18detgabby]

Ive always wanted some HKS cam gears, but never can find them.

[Robert90sx]

Also turns out that the engine was tapped for an oil pressure gauge. When I tried to fire it up, it started to shoot oil all over the ground. There was a whole drilled into the gally below the oil filter.

See, its alot like getting married, and after thinking you have the perfect woman, and it turns out she used to be a p0rn star. It might sound great, but then you have to worry about what other abuse people have done before.

"You may want to check the compression before you go any further because when engines have add-ons like that, they've been raped and sometimes over-boosted which will lead to cracked ring lands and/or all types of other issues."

I am going to pull the cams, and possible the head today. I have taken the red pill, I want to see how far this rabbit hole goes.

[HighwayStar22]

I'll take an OS Giken unit. haha you just let me know if you want to get rid of that stuff. I'll be right here wating.

[Robert90sx]

Looks like she is done for. I know that your suppose to get the car up to operating temp before you do a compression test. That understood I figured it would still be a good idea. Here are my numbers.

dry 65, 95, 90, 110wet 75, 100, 110, 130

I thought the gauge might have been bad, so I got another one. Same results.

At this point it sounds like I have fried piston rings. I have read up on results from warm engines, and it does not sound like there is a huge difference. Anything I might be missing?

I will post this as a new topic, so please feel free to offer suggestions there.

Just to sum it up, screw nagasaki motors. Sure I might be able to sell all my parts and have enough money to buy this engine again, but why. Anyone want to buy a used OS Gilken for 900 bucks?

Been around along time my friend and am no stranger to the trickery of this business. That engine was dogged by someone here in the U.S. that blew the engine and swapped for an SR. Usually when the turbo is gone, the importer is the swiper. Automatic CAs are better and are usually the higher compression CAs.

I wouldn't mind selling mine

[Robert90sx]

I had that thought come to my mind. I am so upset, I feel like thowing up. Monday I am going to take the head off and take a look head gasket and pistons. As long as my pisons are not f'ed I will rebuild the short block. If they are broken, or anything melted, I am going to part it out, sell the 240, and get my self a Geo Metro.

[bentvalves]

reeelax dude the pistons likely are toast! If they are dont give up.

I have 3 pistons in good shape kicking around standard bore size I believe.

just pull it apart and have a good look at the bores, pistons, crank, rods etc and update.

[mbmbmb23]

Could be a cracked ring land in a forged piston.....you might get away with a mild hone and new rings.

[float_6969]

Sorry for the bad news buddy. You've got too many good parts there to give up on it though.

Pull the head and take pics. Those compression numbers look like toasted rings as the others have said, but pistons aren't too big of a deal either.
