Original Message from me:
On behalf of many Celica enthusiasts at http://www.NewCelica.org, I would like to inquire if there are any plans to release pistons, both high compression and low compression pistons for the 2000 Celicas.
Response:
Well, good question! As a heads up, we've got the new 3SGTE turbo pistons
due to be released at the PRI show along with the 18 other new
"turbo-series" pistons (all the popular imports)as standard Wiseco kits.
Each of these 19 engines gets their own forging design (we do the 2618 alloy
forgings in house)so internal milling (weakness) isn't needed to achieve low
weight. Now for news on the 2ZZ, We've done them as customs and I can
squeeze a maximum of 7.1cc (stock V.P. depths and diameters) which nets
13.1:1 compression when a .030 piston to head clearance is used (minimum).
This was w/ a 40cc cylinder head and a 82mm bore size (stock). This piston
had a 1.234 compression ht. (stock) so we could use the stock gasket and
quench clearances. We could knock this down to any volume you would like to
run. Now the interesting aspect is the nicasil-like coatings on the bores
(can't be overbored conventionally). We can build the pistons for standard
bore or maybe .0005 over, or you guys might start sleeving these bores at
some point to accommodate bigger bores, either way, our rings are
compatible. If you guys are interested in a group-buy of some type (lower
pricing), let me know as we're at minimum quantities on custom orders of 8
pistons and 3 week delivery. Racer pricing for 2001 is normally $130 per
cylinder including rings and pins. Feel free to post this. Thanks for your
interest! Brian Nutter 800-321-1364 ext. 3177
Just giving the heads up because despite some companies lack of enthusiasm (Greedy), there are also companies that love to jump on and make products. So keep sending out emails to assorted companies and we can find stuff.

I have a few questions though, what kind of a problem with boring does the "nicasil-like coating" on the bore pose? I know it was coated, but if we bore and take off the coating, will this increase friction and load in the cylinder?

Also with new sleeves, can we bore the sleeves, then get it recoated with the same sort of nicasil material?

This is some GREAT NEWS for looking in a new bottom end. Too bad I won't have this money by now. I'm planning on rebuilding my motor in my Engine Repair Class.

Come on guys, no enthusiasm? Everyone complains about not getting stuff, but when someone is willing to make us products no one gets excited?

i didnt understand seeing n e thing in there about lower compression pistons.

what would higher compression accompish n e way??????

Great Job

Wiseco pistons are used by Endyn. If you guys remember that Teg(tony) video I posted a while back, he had Endyn Pistons in his motor. Great Work

Sounds promising! Now, what does Wiseco need from US to help make these products a reality? I'm down to do my part to help get some real performance engine products for us.

I'm glad poeple are talking to these companys rationially. Its also nice to see that even if we have to get on off we can get them w/o too much trouble.

Yep, for those who don't know who Endyn (Larry Widmer) is, please visit his site. You'll pick up on quite a bit of interesting subjects there. But anyways he takes Wiseco pistons and machines them to his specs.

The great thing about Wiseco is that he can make pistons to spec. Dome shape, ring spacing, size etc. He can do whatever.

gnes100, Higher compression generally creates more horsepower (however sometimes they can't be run on pump fuel.) There generally is a limit to how much CR you can run before you start pinging on pump gas. IMO i think 11.5:1 is great already, but I would definitely like to see them fitted into some bigger bores.

Oh just another thing, he can make them for stock bores, stock rods and whatever may be. He thinks 11.5:1 (yes I know thats stock) and 9.0:1 should be great, not only to make but to use in our cars. What does everyone else think?

Sounds good. At least hes willing to do the custom work with no problem. So I guess it is a reality already.

Just a few question. Would someone be willing to put together an actual kit? (Best gains + Most reliable) A kit would be nice, but what type of HP do you think we would gain from this?

thanks,
~Brett

hey! this is exciting news for those that are using NOS and want FI. People complaining about no lower CR pistons.....well here you go!

I dunno about raising the CR, though, 11.5:1 is pretty high for a street motor already and with no engine management system it'll be tough to get the motor not to knock...

A full kit? I don't know if thats totally possible, with the exception of maybe Crower. You'd have to mix and match parts. But just bolting these parts on, if the Gude package would be so bold to claim 35 hp. I think these parts can up that by a lot. We'll be pushing 200+ easily at the wheels resleeved bores with pistons, cams, springs, valves, ported manifold, hytech header and exhaust. Dyno tuning time.

I believe this engine is truley potent. With a few mods, I think it will be a monster. I'm conjuring the pot. You guys should try to find more companies as well and post in the general forum list.

Dammm Unity, good job. That is great to know that they can do the lower comp pistons. Did they say how much or what they need to get this thing going? Also, how hard do you think it would be to replace the pistons ourselves? anyone?

I HAVE CAMS TO DONATE! As long as I get my cams back PLUS something for donating it, I'll be more then greatful to do so!

Technically, pistons of the same CR aren't going to give you HP numbers. Pistons of the same CR, partnered with lighter rods, will not give you more power, but will lighten rotational mass. Basically, the motor will benefit the same way it does with a lightened flywheel. Less rotating mass, faster revving motor.

As for kits go, as much as I hate to say it, someone actually give crower a visit. I'm not to fond of them, but they are willing to do the work for you guys, so you're going to have to go with what is available. I'm still wondering about the TRD cams that was talked about a few months back

CelicaRZ: Sorry man, boys at Carboy Motorsports(Not associated with them), couldn't really give me any new info on GT-S performance.

Another company you guys should seriously talk to is Hitech. I believe someone on this board already posted their number and their website. Just a warning though, Hitech headers do not come cheap. The B16A header is over $1,100. It works great though, surpases some JDM headers, plus they'll do custom design also. Basically, they'll re-shape your powerband with headers in any way you want.

About CRs, there are street driven Teg Rs, GS-Rs and Si's running CRs as high as 12:1. But these cars have big cams that love high CR, so unless you have cams that need CRs that high, I wouldn't recomend it. Plus it requires good tuning on fuel maps and settings

Carboy, I've been had some sort of contact with Hytech for a while, and plans for headers will begin after xmas (well because he's working on an Eclipse project right now). Personally I'm having him build me the header with an exhaust system to match.
