Piston poll, what slugs you runnin?

Post by **themadscientist** » Tue Jul 01, 2008 4:10 am

Time to buy pistons, help me pick. What do you have and what is your feeling about your purchase?

Piston oiler notch correct?

Were they weighted?

What was the ring quality?

Were they a consistent barrel size or did they vary a great deal?

Any special coatings?

what clearance did they require?

noisy when cold and if so do they warm up quick and get quiet?

I am probably going to get a set nobody has just to broaden our collective experience of the available brands.

I'm running Wiseco 84mm overbore pistons.

Piston oiler notch correct?No. There is a notch on the skirt but squirter hit webbing around piston pin. Squirter modification required.

Were they weighted?Yes. They were within 3-4 grams of eacother. The weights were written on the pistons to show they were "matched". I had them rebalanced within 1/2 gram. A higher priced piston would probably be matched better.

What was the ring quality?Pretty much standard rings with a high quality oil control ring.

Were they a consistent barrel size or did they vary a great deal?Dimension wise they were all identical in every measurement... The piston pins slid in with no resistance either. Spiral lock pin retainers are a ***** to install but very secure.

Any special coatings?Yes. Piston skirts are coated with black anti-friction coating

what clearance did they require?they wanted .003". Piston rings were spot on with the bore size too. No need to file any of the rings!

noisy when cold and if so do they warm up quick and get quiet?N/A

Stockers in the CA but used CP's in the last rb25 I did. No complaints whatsoever.

Post by **boost_boy** » Tue Jul 01, 2008 11:09 am

I use CPs in the street engine and wiseco in the built engine. I've used wisecos back in 1999-2000 and they weren't bad, but my engine management was and it cost me those $500+ pistons in less than 1000 miles. Detonation was the villain, so check my sig................On the other hand, the CPs have been pretty good as well, but then again, there's a much better source of engine management fueling them too.

Since the first wiseco set, I had some adjustments done to the piston ringland heights to get them away from detonation (if there's to be any). I also got modified valve reliefs to compensate for the big bumpsticks. The ring quality on both are pretty competent as well.

Arias pistons in mine, no problems with squirters, no special coatings and have huge valve recesses for increased lift...

Unfortunatley I think they don't make them with the bigger recesses any more, I havent noticed them to noisy at start but others I have talked to mentioned some noise...

Custom CP piston. 83.5mm, approx 10:1 compression with thicker ring lands than standard, full floating wrist pin.

Piston oiler notch correct?YES

Were they weighted?YES

What was the ring quality?GOOD

Were they a consistent barrel size or did they vary a great deal?VERY GOOD

Any special coatings?NO (but available)

what clearance did they require?I don't remember. It came with the spec sheet.

noisy when cold and if so do they warm up quick and get quiet?YES, and YES

Well, they ain't cheap but here are the pistons I am going with.

Toda ain't screwin around, these things are dead sexy.http://todaracingusa.com/category?id=25

TODA will also be doing my machine work on the block. Visa card is hot as a mofo, I might have to go back to stripping.

nice

how much does work for the block usually cost...wen i get down to the gritty i wanna have a good idea how much itll cost me

Post by **themadscientist** » Thu Jul 10, 2008 10:26 pm

I'm in Japan so the price is big yennies. They will be boring and honing the block with a torque plate and flycutting the deck to true it up. It's going to set me back about $800. I have to ship the block to them in mainland, I'm down on a small island.

Post by **float_6969** » Fri Jul 11, 2008 3:00 am

That's a RETARDED amount of money for block work!!! At the shop I use, boring is $25/cylinder, $50 for the decking, and another $25 to hot tank the block.

Post by **themadscientist** » Fri Jul 11, 2008 3:22 am

Everything is expensive here. The old man here who doesn't know what a torque plate is and can't even replace valve guides charges over $55 per cylinder and has tools that look 40 years old.

Toda builds professional racing engines for GT300, F3 and F4.

Anyone using Mahle pistons? I know lots of race teams use them, and they have been in the piston business for over a century.

Post by **themadscientist** » Fri Jul 11, 2008 12:13 pm

I looked them up, no CA pistons on the shelf.

Post by **sicj** » Fri Jul 11, 2008 2:54 pm

wow impressive!

that's the only thing I wish I had when I was machining my block was a torque plate. It was crazy to see a block distort as much as .003" when the plate was removed after machining.

So with $800 block work and $800+ pistons and I'm sure your getting other crazy parts to go with those as well...what are your goals for this engine? 500+hp? I mean that 400+hp CA wasn't nearly as built up as yours sounds like it's going to be...

Post by **themadscientist** » Fri Jul 11, 2008 11:39 pm

Goal is it doesn't blow up. This will be my first build and my first time messing with the Haltech. It will be a long slow process to turn the power up. 300 would make me happy but I am building it to take 400.Nothing crazy just a daily driver.

I run CP piston great piston and they have prove 330Hp/L

^ Yeah, if they work for you, they should be good for pretty much everyone else.

Post by **r34 gtr** » Tue Feb 02, 2010 9:22 am

How did this thread get bumped when there is no post after my last one, in '08, and it was pre-bumped before I posted this?

Side note, still bummed that both Arias and Mahle do not offer off-the-shelf CA18 pistons a year and a half later.

The Matrix did it...

Whoa, Wiesco finally fixed the no oil squirter relief issue. Awesome!!

CP Pistons for my CA. Seem to work fine to me.

Post by **boost_boy** » Thu Feb 04, 2010 3:43 pm

Stock pistons work just fine, too. With over 400+whp on tap, countless two step scenes and some serious 28 pulls, the stock pistons in my 240's CA looks fabulous. Remember guys, it's all about the tuning. Stock pistons are just as good for most of your needs. Spend the money on something else.

Why did you have to go and mess-up those good pistons. They have proven to me to be good for a consistent 500hp. I mean, I tried to beat the oil out of this engine and the piston crowns weren't even burnt. Actually, the whole thing looked so good, that I just wanted to put the new oil pump on and just throw it back in the car, but that wouldn't be Deeish. I just polished the crank and am now waiting for over-sized rings. Oh yeah, the engine was rebuilt in Japan before I got it, so I get to clean it up and continue to blast it. Get another stock block, clean it up and lower the timing on your EMS.

No thanks, I'm just going to bore it to 83.5mm and throw some forged pistons in there for some peace of mind. I was considering going with a larger turbo as well, something like a 3071R or TD06-20G, but this is all six months away at least. Graduating from college and getting a real job comes first.
