Which Pistons to use??

[LessIsMore]

Wiseco pistons are supposed to be a better street pistons than JE pistons with less piston slap. Wiseco pistons are nearly the same price as having your six bolt rods machined with 2G pistons. Go this route if you want more compression.

I chose to stick with the six bolt rods and first gen pistons when rebuilding my motor. My compression numbers are a bone stock 165psi in all four cylinders. Factory internals have proven over and over again that they're capable of handling almost any street setup.

Ok let me get this straight you are going to spend $700 on some 95 pistons, and machineing of your rods. For an extra 50- 75 dollars you can have NEW eagle rods and a new set of Ross pistons, which you can choose your compression.

 

[1fast97gsx]

yea $700 is ridiculous .. I had my rods machined for $90 back in the day. 2g pistons should be no more than $275 with rings and pins.

 

[VRMAN]

Budget: Get some 2G pistons with 90 rods

Race motor: Wiseco pistons and Eagle rods is always a good combo

Whew! I need to get my goal out here clear. I just want to build the 6-bolt up to be 25% better tha stock. my deal is when I replace something I like to do it with something better. I am quite sure that the '91 rod and the Wiseco's will fit my goal. Thanks guys. Mark

 

[donk]

how about the ross pistons? are they any god?
and how are they as a street piston?

Hey Alfred nice to see someone who is a DSM fan from Sweden! Here's is what I have found.
Wiseco's-my choice, not the strongest

JE's-porly designed for DSM's and can seize engine

Ross, too heavy, +8 grams each I understand.

They are all good or would not be in business. I have run JE's in another turbo car and not a problem. Are Ross pistons @ +8 grams heavier than stock, I don't know. Wiseco's are not as strong as JE's but probably much stronger than stock. It comes down again to how much power you expect to make. I am running a garrett 50 trm and plan for 20 PSI. Wiseco will work for me. Mark

 

[anconover]

From what ive seen and heard, i would never run a JE piston in anything. ever.

Ive seen weights, ive got a list somewhere, Ross are heavier than wiseco, but not by all that much. And they can take a little more abuse. Ross or wiseco is my piston of choice, wiseco is probly a better choice for a street car, as the recommended piston to wall clearance is .003 where Ross tend to be run .004-.006.

It tends to be a better idea in my opinion to run big rods with an aftermarket piston. Thats IF you have big rods already. 250$ or so for 2g piston, + 50$ to machine 1g big rods for them. An extra 50$ will get you a set of wiseco's to run on your big rods. Now aftermarket rods add alot more than some are looking to spend, and really arent necessary for most. Aftermarket piston/big rod combo is said to be good upto 500whp.

Ross are 8 grams +-1 than Wisecos, and are still lighter than stock I believe.

I, personly, wouldnt go that far. Yes, they dropped the ball on the pistons for the 4G63, but for domestics I would run JE any day of the week.

:laugh:

You can get Wisecos with rings and Eagle rods shipped to your house for around $800...

If you pay $700 for wisecos on 1g rods I think you should be refered to some people in white coats who have nice padded rooms you can play in..

"If you pay $700 for wisecos on 1g rods I think you should be refered to some people in white coats"
do you mean the chemists???
/alfred

 

[sweet97]

The Wiseco's are $350. w/rings and would be partof the assembly.
Buschur charges $700. for '95 rods, pins and rings mounted on MY 1g rods with machining.
The days of knowing chemists are long gone. I don't even know if Owsley is alive!

 

[anconover]

i think he was referring to a psyche ward/doctors.

But buschur is way overpriced to begin with. Theyre on crack. Its 50$ to have the rods machined for 2g pistons.

 

[sweet97]

Owsley manufactured some of the best most potent acid in the 60's and I would imagine a few ended up in psychiatric wards. Look at what's his name from Pink Floyd back then. Sid Barrett.
Wrong forum. That maybe to fit the rods to a 2g crank also, isn't more machining needed for that? Anyways I was just giving figures and I am going forged.
Next is oil pump, I see covers with gears, is that what I need? Direction to a post on this would be appreciated. Oh, what brand of bearings are the most popular? And DO NOT TURN CRANK, correct? Thanks, Mark
PS: True ARP mains require extra machining?

 

[anconover]

Youll want a cover w/gears. Its like 175$ at slowboy. As far as bearings, people use many different kinds with no real problems. ACL, federal mogul, Clevite are all perfectly fine to use. I dont like turning the crank, just a simple micropolish as long as everythings in spec. And ARP mains will require a line hone most likely. At least have them checked when torqued down, most likely they will need a line hone.

The point is you can get Eagle forged rods + the WISECO's the pins, rings etc come with them for a combined total of $800...

 

[anconover]

actually more like 725. But i dunno why thats the point, he can get wiseco's for 350$, and throw em right on his rods. Or get his rods machined for 50$, and slap 250$ 2g pistons on. Doesnt seem an aftermarket rod/piston combo is in his budget.

 

[MNGSX]

Its his car but with Eagles around $350 ish another $300 in the grand scheme of car ownership and engine building is'nt much.

 

[sweet97]

It's not just a matter of cash as I have $3200. in my TRE-Spec tranny with clutch and flywheel. My present motor inthe car is just fine with no problems. The 6-bolt is a replacement to get me another10 years out of the car, maybe more. I am not shooting for a HP goal and the car may never see a track unles I go to watch ANCONOVER run his as we are near the same track. Not to say i never run the car hard as i do. The 1G 6-bolt rods are an upgrade and the WISECO's are too. Perhaps put the cash into cams/headwork. Thanks

 

[anconover]

Thats another 350$ in his pocket tho too. Hes looking for 12's, so he really wont be exceeding 350whp most likely. If he does, it probably wouldnt be by much. So the eagles arent necessary, so it can just save him some money is what i mean.

 

[MNGSX]

get me another10 years

Get the eagles..

You can go thru alot of boost addiction in 10 yrs.. You might as well be ready for any turbo you can throw at it.

 

[DevilSperm]

subscribing to thread... im trying to decide what pistons and rods to go with

 

[keltalon]

what about the nippon racing pistons sold on ebay. are they any good! are they really better than stock like the guy claims?

 

[sweet97]

David buschur caught wind I was considering a shortblock rebuild and offered a stage 3 at a good price. I may just go that route and get forged pistons/RODS and the rest that comes with a stage 3 block. Head and cam work would need to be deceided upon and he recommends the HKS 264's for my goals, $1000. for the machining and ss valves, prt/polish, stock springs and retainers, basically a stage 2 head. I have some thinking to do!! Thanks all, ark
