lol

[BoostedSchemes]

thats the sort of shit i would do

[Joseph Davis]

I bought a $700 lathe so i could make that not look completely stupid.

[dvst8r]

I think with a die grinder and a little time it could be made to work, just have to get rid of a few sharp edges. Then get a syringe and some water and make sure there all close, good to go. 

[Teg2boo]

He just didnt finish the job, I would rock them anytime.

[Doug]

Funny part is he sold the engine. Would have been funny if they had installed it and try to start it.

thats acually very common with some types of engine building, diesels, porsche's ect

[d112crzy]

That can only be the work of a stupid ass puerto rican. THey're always trying to do something on the cheap but always end up fucking shit up.

Vitaras also have a very thick crown.  With how the 1.7 stroker setups bump CR up to a horrible 9:1 CR, lathing a piston down is one of the ways in which we've discussed lowering CR back down to a heavenly 7.5:1.

we talked a guy into JB welding his pistons to raise the compression.  the fake magazine article is awesome.

ahh holy fuck thats funny, did he ever run it

[Robb]

Local guy made some pistons out of blanks on the grinder. Ended up being 14.5:1 compression and in a 351w stock bore and svo heads made 612 wheel Hp.  Trips the 60' lights on the rear tires in a mustang cobra II.

Now that is hard core.

homemade piston would be the shit

interesting. would you be just facing the piston off and making a flat top out of it to lower compression? Or maybe put a slight dish on the piston?

[Joseph Davis]

need a Vitara to cut in half before I can comment

And what rods are you thinking on using?

If I recall correctly, the D17 BE width is quite narrow.

Crowers maybe, but that seems a bit too spendy for a project that is probably based off of mostly free parts.

ls rod swap?

Already bought generic forgings from marcj; they hit the door last Monday and they were milled by Thursday.

I do this to DI diesel pistons a lot, which is fun because the combustion chamber is eccentric to the O.D.

By the way its called "turning", not "lathing".

[Doug]

Oh shit I can't wait to see JD's response. Never seen him get called out on anything.

Turning is every bit as inaccurate as lathing.  It's a garbage baby word meant to communicate with simpletons. The actual machining operations possible on a lathe are cutting, sanding, knurling, drilling, or deformation.  The procedure being discussed, if it's called anything, is cutting. 


ok??
