I'm doing a motor build from scratch and I got really a good deal on a SOHC 16v head. Now I just need the rest of the motor to go with it. So I need the GT pistons with the 4-valve cutouts.
I've also got a dyno and a brilliant tuner at my disposal so 10.5:1 should be no problem. I think he's running 13:1 on pump gas in his Integra... his cam helps him out there, tho...
I might try for 11, but this is running on pump gas, so I can't get too crazy.

mrbell- PM GeoZukiGti and ask him about another set of dohc pistons ---- - --- ----

good luck.

how much CC's is the dish in soch 16v piston??
i have 1 set in hand and its sound to be good for me to put a gt crank in my sohc 16v shortblock and put a gt head on an "low to medium" boost it
thanks

I do not know if the DOHC head or the crankshaft will work with the SOHC block.
(Try asking Suprf1y about those questions.)

Please read wgotzman's orignal post to answer your piston question.

good luck

We tried something similar with my 96 metro. We swapped from an 8v to a 16v head from a 98 metro lsi along with a few other important items. I am unsure of the current compression ratio, but it only runs well on premium 93 octane, it starts to ping with 91 octane. I think we are the first to accomplish this.

Your compression ratio would be just under 11-1

are mk1 direct fit on earlier 3 cyl??
same bore?

Yes.
1.3 8V pistons are also the same.

suprf1y do you think i can toss mk1 pistons into my mk4 3cyl?? will it worth to make it faster?
thnks

You can, but IMO, it would be easier, and just as effective by removing the head, and machining 1mm from the gasket surface to increase compression.

ok man i will do that
and get more power and use to the 3tech stuff already in the car right??

btw the car feels great with the cam gear and camshaft

if you want cheap used ones I have 4 with rods and crank in a whole running gti motor im not using

I'll take those!

Cookie, if you want new ones: http://www.g13b.com/

He sells good stuff, is really good to deal with, and his shipping rates are most reasonable as well.

I'm going to be getting some things for my Swifter soon.

so do you have to swap out the gt rods to? or can i still use the stock swift rods? gti look, I'm retarded stronger right? what kind of gains are seen from doing this mod? this is something i will do when i rebuild everything!! thanks for the site foo!

No,

16V SOHC have the exact same rods and crank as the 16V DOHC, the difference in the rotating assemblies comes from the GT having more meat on top of the pistons.

I'm not 100% sure, more of a 99%, that the engine will go back to being interference type once the higher compression pistons are used. So make sure you change your timing belt regularly.

The same gains as any motor see's when it goes up in compression, more torque, better fuel economy(needs atleast midgrade), and generally more power.

Your welcome on the site. If you want parts from S13B, you can have them, I want them as an excuse to use my dremel tool more. It's all about the tinkering...

ya i hear ya on the tinkering! no i wont be doing this kind of sawp anytime soon. but good to know!!! it sound like it be a nice lil addition. for now i will just get me lil bolt ons. i got a 50mm tb comin for mike cove. and then ud pully and cam. see what happens after that.
oh and are the pistons on g13.com 79 for the set or each?

now would be wise to do anything with the head? im looking for reliable power not just all out lets blow this thing up power!

take it to a shop,

Have them check the valves make sure the seats, guides, and valves themselves are good.

Have them make sure the surface is flat, usually they pass it through the lathe and take a few thousandths of material off.

They should reassemble it, and it'll come back to you looking like new.

Mike, sorry to bring up an old post. But what if i angle mill a gt head 0.030" from the intake side and 0.050" on the exhaust side. That in combination with cultus pistons (11.5-1), would that be sufficient for a new CR of around 12.5-1?
Assuming head gasket thinkness is standard (1.2mm compressed?).

Yup. That should work. Just be careful you don't cut into the intake valve seats.
