rofl...  no, #6 might not do me much good... ;)

I might be interested in the other 5... are they out?   What size?

Sleeperred90, do you have a complete set of 6, or maybe one of the same size that GutlessSupreme has?

You've got 5 of the TGP pistons?

Yes, I see that...  I'm mainly concerned with quench area of TGP pistons vs 3x00 pistons.   If the TGPs are not very much worse than the 3x00, I'd rather have the 1 point less compression.  :)

Just so we are all on the same page - I'm talking TGP pistons + 3100 heads on a RWD iron block (I have a solid iron 3.1 right now)

How does the quench of the TGP piston/3x00 head combo compare to the quench of the 3x00/3x00 piston/head combo?

It is my understanding, that the TGP is 8.8:1 cr, while the 3x00 is approx 9.6:1?

I'm wondering which piston will be better for turbo application....   I know quench is important, and as long as the TGP piston offers 'good' quench, I'll go that way.

Hey, it's gotta be better than my iron head 3.1 piston's quench area :)

I need a set of 6 TGP pistons...  let me know what you have!!  new OR used

well, instead of re-posting that image (which would be GREAT) how about anyone describe the routing of the PCV system to me?

Arg... can you repost that??   So very sorry!!

Can anyone get a pic of the emissions sticker from a TGP, showing the PCV routing?

I would, but G'ville is closed down till Spring!

I will, however, be getting a baseline run with the built 3.1 @ Orlando Speed World (after breakin, of course) and then return with the 16G @ 6-7psi, and go from there.

I had asked about the Mahle pistons before....  anywho, if you guys are interested in a turbocharged 3.1 RWD in a Camaro, check out the progress on the new block setup...

Don't mind the pic of Vortex and the cam...   just flipping off the car, because this whole thing has been a severe PITA!

I just hope I can beat a 2000 Civic VTEC after the 16G is done.. (16.4 vs my then 17.07 stock 2.8)

$108 - Mahle Pistons p/n #027250

The guy was telling me those are stock pistons for my application?   Now, are they going to be the same beefy construction as the TGP # 027260?   The only difference I'm seeing, is the dish....

Found the Mahle pistons for my application - #027250, vs your 027260.   Now the question - are the same beefy construction?   I'll call tomorrow.  Does anyone here know?

Chevy 3.1-T Camaro/Firebird 90-92 - Master Kit
INCLUDES

Federal Mogul Moly Rings
Federal Mogul recessed head Pistons
Federal Mogul Rod Brgs
Federal Mogul Main Brgs
Clevite Cam Brgs
Melling Oil Pump
Melling Timing Components
Pioneer Frost Plugs
Fel Pro Gaskets

$311 (called for price without lifter/cam)

Turn my 3.1 stock crank .010/.010 and have it nitrided, then use this kit, with a Melling MTC-5 Cam Kit (204/214 @ .050 - .420/.443 lift) with a ported 16g blowing 10-12 psi.

I can get the kit without the pistons, that's not a problem...  I might even be able to get them with the Mahle pistons.   Difference in dish between the Iron headed n/a RWD (not the FWD Al headed n/a!) and turbo (FWD Al headed) pistons -

Dish specs -
(RWD 3.1 Iron Head Engine - what I've got)
COMP: (2)1.50mm OIL: (1)4.00mm
COMP DIST: 1.442"; PIN DIA: .9055"
RECESSED HEAD .105" DEEP x 2.913" DIA

Dish specs -
(FWD Turbo 3.1 Aluminum Head Engine)
COMP: (2)1.50mm OIL: (1)4.00mm
COMP DIST: 1.442"; PIN DIA: .9055"
RECESSED HEAD .265" DEEP x 3.000" DIA

The FWD 3.1 pistons will work... but WAY too low a compression to be of any use to me.....  7:1 or so.   I'd like about 8:1 or so.   Does Mahle make a RWD 3.1 iron headed piston?   Or, a 3.1 piston (3.539" bore - .030" over) with about a 12-14cc dish?

Haha...  what kind of power outputs are you guy's getting from your turbo 3.1s?    My camaro weighs in at 3150 with me in it (weighed on a real scale, lol)

about 2950 without me.    I'd like to run 10-12psi on the 8.5:1 cr 3.1, iron heads, with the 16g.    I'd also be running ported/polished heads/intake, 3" exhaust (all the way, no cat), and a 204/214 @ .050" cam.   Any ideas what she'd run, or how much power she might make?

Ok, just got your guy's piston info (from Federal Mogul) - Your pistons seem to have about a 30cc dish, wheras the stock 3.1 has about a 12cc dish.   With the 50cc iron heads, 30cc dish gives me like 6.9:1 cr...  WAY too low!

Appreciate the help guys...  running a 16g (flows about 520 cfm vs T25 405 cfm)

And technically, it's still a 2.8 in the Camaro.  I'm building the 3.1 now :D
