Ok, TECH43 RACING INC. (steve@tech43.com) sells these 85mm piston kits that turn a sleeved b16a ( 85mm) into a 2020cc monster, using a stock LS crank and stock LS rods.... here are some pictures:












<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by Tech43 Racing inc. &raquo;</TD></TR><TR><TD CLASS="quote">
*custom machined buttons to support oil ring. this is how i can fit all that crank and rod in a b16a block. yes, you still retain the ls 1.54 rod ratio
*custom .708 lightweight tool steel wrist pin. rod must be rebushed to this from .826
*dedicated valve reliefs and lots of internal milling to reduce weight. piston weighs in at a mere 255 grams! most off the shelf 85mm pistons with this dome weigh around 315g.
*compression ratio is 11.5 to 1 with a b16a head unmilled and stock gasket.
*kit comes complete with rings-wrist pins-locks-buttons
*these pistons have reliefs that will clear cams up to 13.00 mm of lift.</TD></TR></TABLE>


Now of corse this is ausome, only thing is they are 85mm...
i heard a lot of b16 people are intersited... if they were in a 81.5mm bore instead of 85mm, so they wouldent have to get there block sleeved, they would just slightly overbore and slap these in.

Displacement with 81.5mm bore 89mm stroke = 1857cc
Displacement with 85.0mm bore 89mm stroke = 2020cc

now what im trying to do is to get him to realize that people want the 81.5mm and for him to stock up.

The kit costs $585.00, just slightly more than regular forged pistons!!!!

So lets hear it guys, what are you interisted in?!


<FONT COLOR="red">NEWS FLASH!!!</FONT>
The 82.00MM kits will be ready to ship on 6/28/04!!
82.00mm = 1880cc

1.9L b16a!!!

email him at STEVE@TECH43.COM to reserve your set!!!

its not really a kit though, its custom pistons and rings.. you could call arias and theyd most likely have the specs for these.

SkRiBLaH

its a piston kit, not an engine kit, and arias won't give you propietary specs.

There arent any propriatory specs for those pistons, just a custom compression height and deeper valve reliefs. You can call Arias or any other piston manufacturer and tell them you are using a B16 (7.997) with a LS 3.504 crank and LS 5.394 rods and they can make it for you no problem. If I remember correctly, the compression height needed for that set up is .851. Also, I noticed that the above piston set had a .708 pin which is really tiny. I wouldnt want to go any smaller than a .748 (D series) pin which will actually allow you to use a aftermarket (Eagle, Probe, Crower, Scat, etc) D series rod with the LS crank. That will definitely keep costs down.

Hey whats up. The reason we use a .708 pins it there is no room to run a .748 pin.
The ring stack it tight now and would be hardto squeese the .748 pin inside. look close at the piston and you will se what I am talking about. The .708 pis is just fine if you rember correctly Lisa kubo Ran a .708 [pin in her turbo motors in the Civic. You will not have any problems with this pin it is a good tool steel pin.

If any of you guys have a question about these pistons and you can not get ahold of tech43 just let me know. Keep in mind tech 43 has alot of these kits in stock.

Wrong, there's more to piston specs than just comp. height and valve reliefs.

Yeah, i was kinda looking at the ring pack after I posted. Its a very tight fight even with the .708 pin. I dont know though, for me, on a daily driver I think Id stick with the .748 with an even tighter squeeze just for my own peace of mind.

Your right to an extent. When ordering a piston from a company that already has a set forging design you dont need to supply many other specs other than the bore, stroke, valve relief depth (figured from the lift on the cam being used). The rest of the specs are all taken care of via your respective piston company. When you call to order a piston for an aplication like the one above the companies are only going to ask you questions such as these:

What block/head?
What bore size?
What stroke?
What rod length?
NA or FI?

Thats pretty much it unless you are going with an all out piston which is of your own design, different forgings and the such.

it actually will work, and has worked. Jakes Racing Engines has used pretty much exactly what I had calculated above. When you think about it, its not really THAT drastick of a difference. I think there is still room to run the .748 pin from what I can see. Its all your choice, for my own peace of mind though. Id rather run the .748 pin.

WHen you have to get the B series rods rebushed at $20 per rod, yes I do think D series rods are cheaper.

neat setup for sure...id be interested in this setup as a backup setup...

SkRiBLaH

stevel

with this setup you're now going to have the LS rod/stroke ratio, correct?

so where does that get you? you basically have an LS bottom end.

wouldn't it just be easier to get an LS block?

not hating or trying to make it seems like this is a bad idea I just don't see the advantages other than running forged pistons. with LS blocks so cheap it's just an odd thing to do. I guess if you have a b16 block already, but just seems easier to go with the LS, plus you can use all the OEM pistons that are available.

the piston does look sweet though.

damn im a hypocrit

true though just get an LS...

Dude, did YOU read the first post? This is that that you can use LS crank, and LS rods in the B16 block, so obviously..you're going to have the LS 1.54 RS ratio....

The B16 is like 1.7* or whatever.

i did reread it. it says 1.54 LS r/s ratio.

I did miss that exact line but what you said is wrong. 1.54 is the LS r/s ratio, not the b16.

I'm just wondering what the advantages to doing this are. Seeing that b16 blocks are just as cheap as LS blocks and both seem to be plentiful.

so...I guess you know best. Forget the fact that tom from arias has already said the .748 is too big. Damn, I wish you were around when me and the piston designer at Arias couldn't get a .748 to fit. You could have shown us a thing or two.
And forget the fact that we are running .708's with no prob's. and lisa kubo? its not like she is making any power on her .708's. I'm sure your monster hp engines are exceeding her numbers by far.

thats funny, i'd like to see you use D rods on a ls crank. I guess you dont care that the D rod is .037 NARROWER than the B rod. I guess you didn't know that though. I mean, how would you? The .037 difference isn't really a factor, when you are bench racing, and commenting on other peoples parts from the sidelines.

i've got an ls crank and rods right now and i've been considering dropping them in my b16 that is currently on its way but i've been told a million different things as far as modding everything to fit, and some have said the oil squirters have to be removed, but it sounds to me like they don't, the other major concern is obviously the wrist pin which i've heard has to be moved southward and so i guess thats why the pins are so small, but i guess my question is other then a set of these pistons what else would i have to mod to make the ls parts fit

edit- what compression are we looking at w/ these pistons on a stock gasket, etc
edit number 2- im an idiot i just saw the compression in the specs

unfortunately you dont have a need for squirters with forged pistons.

compression is 11.5:1

and the only thing other than the obious LS crank and rods, b16a block that you would need is the rods re-bushed to .708, or just get some rods already re-bushed from tech43.

If you have the LS block its stapmed b18 and if you got the b16 block it's like sleeper status.

yea, that would esp. be valubale in EU, where they get taxed on their engine displacent!!!

so think, with the 85mm kit, block stamp = 1.6, true displacement = 2.02L!!!

I'd buy an 81.5mm kit! Stock up!!
