Yes pics of the pistons and rings ( close up of the rings) would be good.

ALso how far down from the top is the first ring land/groove on the piston?

WHat is the deck height of these pistons?

The CC thing may be because of the amount of room the piston has to allow for such things, in other words it may not be able to have any more CC's than what was given. As long as the compression is atleast down to 9 to 1, I would not make any changes to that. Carefull measurments will need to be looked into and figure the comp that you really have. If its to much then a thicker copper head gasket may be the anwser simply because it may weaken the piston to go farther on the dish. The piston top needs to hande the heat in a turbo app and its durability and the ring placement are very important.

Yes, Weisco is a very good piston and if these are setup for the 198 rod then you should have a great piston setup if they got them right (key words there, if they got them right). IMHO the 198 rods should be the very shortest rods ever used in a slant simply because of piston packaging and geometry, and then only because they are there and cheap. With this setup the slant is in much better geometry than stock and is a step ahead of the factory setup for a few reasons. The shorter factory rods can work, but I have noticed they tend to wear the cylinder walls more becuase of side loading of the piston. With the longer rods, Weisco pistons better skirt design, and the thinner rings you should have better ring seal and durability than any slant you may have had in the past. If you could swing getting a plate to use when the machine shop hones your cylinders you will have instant sealing with the rings when the new engine is fired up. No break in needed for the rings which means they can hone the cylinders with a setup that will last much longer becuase it does not need to be a wrough crosshatch pattarn to seat the rings. Our slants are tough and last a long time, but the ring seal is sloppy on most that have any kinda miles on it because of these things.


While your at it you might as well post some close up pics of the other stuff, no matter the brand.


Am I understanding right, they send you a cam when the kit that didnt call for one, was this at the same price ? Any numbers on the camshaft, or cards to give specs ? They sale Schnider cams which are a great company and are suppost to have very good cams, but which cam they may have sent for a turbo app is something I am wandering about. On there web site they show a 274/480 cam that would make a great turbo cam with the right valves. There bigger cams are kinda backwards from what DOC has found to perform good on the slant, but if the valves where sized right they would be very good cams IMHO (need a smaller exhaust valve than normally installed, (maybe stock size with bigger intake valve). THey would work out good for a turbo app if they where in a range that the turbo could work with (higher RPM bigger turbo setup) using the standard 1.7/1.4 oversize valves.

Also on the cam bearings that may be a problem that has been documented before and can be expected as something to watch for on all brand cam bearings. Not sure if its really a bearing problem, or the cams themself not drilled correctly but it something that is run into quit often and can be fixed with the right attention.


As far as what I said earlier in the post before, I dont mean to be sticking up for them. Just pionting out a few things about what I seen you got. I have never bought from them, nor do I have anything to do with them. I just know they are one of a few people that even offer anything higher performance for the slant. I called them once about there cams and copper head gaskets and they where quit helpfull on the phone anyway, but I havnt got around to buying the head gasket I was asking about. They said they could get any thickness copper gasket I needed, or even get custom grinds on the cams, but it would take a few weeks to get it. I have learned in the past when getting anything custom to not push your needs to a deadline, but order with plenty of extra time to allow for things like this becasue it seems no matter who it is that things tend to happen. Although I am not sure what to think about them charging your card when ordered, that sometimes can be a sign of a company that is struggling for money, but it may simply be because the pistons where custom which is normally a no return kinda thing.

Anyway post sum pics, and any specs of parts you may have (compression height of pistons, cam specs,ect,ect) and lets see what you have to work with.

Also was this going to be turbo build, or was just thinking that because the pistons where speced from the turbo 2.2 pistons?

Hi Jess,

Yes, this will be a turbo engine. That is why the piston dish volume was important. I have a set of 198 rods as well.

I will get a picture of the rings later.

No specs on the Cam, and it came at no extra cost. I suspect it is a stock replacement.

Pistons-- See pictures below.
