f2t pistons in fe3 - Page 3

**shwine617** · 8-2-07, 11:29

yup, that would be my 1st head gasket. I got the motor already togther and I never pulled the head off, just changed the crank. The guy I got it from ran it under boost, so I don't know if it was already damaged. My tune was pretty close, but there was a bit too much timing in it. So that could have done it. That happened in about and hour or first driving it. you learn from your mistakes

**fredio54** · 8-2-07, 11:52

yep, you sure do, esp when they hurt like that. cool picture though :-)

point was to illustrate that [shizzle] like that doesnt happen without as you say "too much timing" etc.

bought another fe3 wich i"m gonna pickup tomorrow. also have plenty of f2t pistons laying around. have 4 pistons wich are pressed off the conecting rod so one of these days gonna asamble the kit and liter it out.
didn;t post pix of the pistons yet because i dont have them back yet. a friend of mine pressed them of the conecting rods and i stil didn;t get them back yet. will post pix soon!

check out this 140hp wheelbarrow

Does anyone know how deep the dish is form a F2T piston and a F2 piston?

Talked with Bakmans tonight. If you are taking a 2.2 crank with a FE rod an a shaved F2 of F2T piston that would be a nice stroker option correct?

A normal FE-DOHC piston is a few mm below the deck. By this option the piston will come 4 mm above deck. You shave off that 4 mm minus the thickness of the gasket and minus 0.7mm for the squish. Than you will have a high compression 2.2i 16v, correct?

(I have here a F2T engine, F2 engine, FE-DOHC engine and a FE-DOHC shortblock. Tomorrow, if it's dry i will take the F2T and the FE-DOHC shortblock apart for some messurements)

Not correct...As far as I am aware no one else on the forum is using shaved F2 pistons in their stroker..
There are various choices as indicated in page 2 of this thread...
Dutch had used both he honda H23 and the nissan Sr20..other than that get some forged ones theyre not the expensive compared to the cost of machining 4mm off 4 pistons, not to mention that you'd be left with about 2mm of material on the top which would easily become a hole once its heated up in the engine.

Because no one else has tried it, it's a bad thing? I don't know how deep the dish is of a F2T piston. But if it's around 3.1 mm deep I will be on the good side. If I take the pistons of a Honda or Nissan I still need machine work be done.

**fredio54** · 8-19-07, 7:33

i think decreasing the ringland thickness by 4MM!!! is a bad thing. there wouldnt be more than 6 - 8 there in the first place. you are welcome to be the first, and if its NA, it would likely be sweet indeed. do the compression calcs first though, as it still might not be that high in comp at all...

bakmans, please do post accurate pics/measurements of the f2 pistons when you get em back. sounds like a cheap way for me to drop my compression for mega boost on pump fuel :-) i'm keen unless i decide to go all out. then i'd go the little extra for custom forgies for all sorts of reasons...

Fredio:

This block will be N/A.

My other shortblock will me prepard for Turbo. Untill that time i would like a cheap high power N/A block.

**bakmans** · 8-19-07, 12:38

yeah i promised you guys pics and they will come. i totaly forgot that i gave my f2t pistons to a friend of mine who had a special hydrolic thing with wich he can press of the pistons whitout screwing them up. stil havend had the time to pick them up.
but as i stated before the pin height is the same.

and as far as memory serves me correctly the dich in the f2t piston is at least 5mm deep so it wont hurt schaving of the piston 4mm. this way you dont make the piston bottom thinner.
the stock head gasket is also verry thick. dont remember exactly how thick but the best thing is to create a quench from 0,8 to 0,7mm so youd actually have to shave about 3,6 mm of. this way you almost have flat pistons ( just as the high comp stock fe3 postons) and you have a little more stroke so your compression would be high enough! ( still havent had the time to calculate it)

**Casejunkie** · 8-19-07, 13:55

The only thing were we not have toughed of is that I probable will lose my non interference clearance.

**bakmans** · 8-26-07, 15:51

who cares!
just replace the belt on time!

**Casejunkie** · 8-26-07, 17:15

I don't
sended you the info you requested

**bakmans** · 9-3-07, 11:14

finaly like i promised

f2t and fe3 piston pix

here are both pistons on one piston pin!

as you can see the fe3 pistonpin lockes with 2 little springs and the f2t pistonpin is pressed inside the conecting rod. you can buy teflon capd that fit in the piston pin. this way you can use f2t pistons on fe3 rods

the f2t rods are longer than the fe3 ones:

**SixSick6** · 9-4-07, 3:15

Is there any chance you'd be willing to CC those pistons? A medicine syrine and water with food coloring is all you'd need. (just clean them up, pour the water in the dish and pull it back out with a syringe, then tell us the numbers)

Are those N/A F2 pistons or GT?

**bakmans** · 9-5-07, 3:25

im working on that! need to do that anyways for my calculations

these are the f2t pistons and the fe3 n/a piston from the lowcomp version!
