What wiseco pistons

Hey guys.

I am doing the DOHC conversion, with the 4G64 wideblock 6 bolt SOHC 8V block. I have 100mm Eagle Rods, and need to know what wiseco pistons will suit.

Would these suit?

Obviously it depends if I need to bore out the block more etc. But is this what I am looking for?

I want to use the stock 4G64 crank with a VR4 DOHC 4G63 head and my eagle rods (same ones from a 4G64 block).

Cheers guys.

what do you mean by duh?

Are the pistons I linked to the type I am after. i.e. they would fit if I order the right bore size? Will they suit the stroker build.

there was one of the guys here that had a number on custom made pistons and it wasnt too bad, they were like $600.00 but you know? I am not a big fan of wiesco's, I ran them back in the 70's and they tended to distort under stress loads

I am not set on wiseco's. I prefer CP pistons. I had a set of CP forged pistons until today as they were for a 4G63 2.0 DOHC build which I changed my mind from. So I sold them and want to get the 2.4 pistons. All I want is forged pistons that don't rattle and will last.

Anyone know where I can get a set would be AWESOME

im working on the same set up and have been eyeing these. My local shop has had great luck with these in evo's making around 800 hp different rods tho.

Do you know.... RACING wrist pins are super light, & super WEAK, too?

Funny, you pay MORE for them, cause you didn't RESEARCH, your options.

I am, 59 years old, I built my first 2 cycle, Go-Kart engines,
when I was 7 years old!

The CHAMPION I was... many engines & parts were given to me,
to experiment with.

The way I see it, LET ME TEAR-IT-UP until *I* make it fail!

Maybe... I was the first to rev those engines to 20K rpm?

Was I born with a silver spoon in my mouth?
More like...a SILVER WRENCH!

Look-up what, the Bible calls a "Wayne". WAGON MAKER! (Waynesmen)

Oh, btw, I have built MANY, Ford 460s, for MANY years.
HP boat engines.

Using the TRW, H.C. forged pistons were ID to what came in a Speed Pro
box. Whom actually built them? Don't recall, Don't matter.

When they first came-out, the cut for the intake valve (2.14" intake valves)
was very close to the top grove, for the upper ring.

Well, *I*, never had a failure. However, within a couple of years,
they re-designed where the upper groove was, giving it a lil'
THICKER area. (lowerd the ring a lil'?)

Point is: When you punch-out big dollars to a manufactor, and the
product fails (when it shouldn't have) their engineers recieve a "bad
piston", figure-out what went wrong, and fix the problem, ASAP.

There are times, when their engineers have nothing to do....
but, they want to keep their jobs, so they are ALWAYS looking-for,
ANY improvement, they can make.

Forged pistons that "rattle", no doubt about it, a forging shall EXPAND
further that a CAST, and Hyper-u expand even LESS!
General rule is: For each inch of bore, add .001" for piston clearance.
If they "rattle", especially when the engine is cold, they honed it,
a lil' too far! OOPS!

Hyper-u engines are built TIGHTER, (good for MPG & emissions & cheaper
, that's all! )
However, turbos, superchargers, NOS is a NO-NO! Read their manual!

And, because most people won't change their oil, often enough...
that is MURDER, to a tight-fitting, Hyper-u piston, and it shall,
FAIL! Seen it many times!

Why are the Hyper-u so cheap?
Think-of.... a piston made of GLASS!

In racing, do you understand what a "Claimer Car" is?

Since you are at the risk of loosing your "race" car, you'd built your engine,
as CHEAP AS YOU CAN!

Does a Hyper-u piston run hotter, as tight as it fits? YEPPPPPPPPPP!

"I keep forgetting to pull my dipstick, once in a while."

...you ain't telling us, what is the KNOWN TRUTH!

Hyper-u are fine for a DD...IF, you'll MAINTANE your vehicle!

Psst, how many miles were on your CAST piston, Starquest engine
before they failed, ON YOU?!

Just another day...
