Forged Pistons/Forged Rods

[timg]

Has anybody ever done forged pistons and rods in a LQ1? I'm wondering who made them and how much they cost. I'm thinking about using small block Chevy forged rods. The pistons would have to be custom. Looking for a 8.5-9:1 compression ratio in a fully forged piston. Thinking about mating everything up with ARP studs and new bearings all around. Any comments/suggestions on where to look? This is still a few months off, but I would like to start tracking down parts before my car is in pieces. Would anybody else want forged pistons with say a 8.75:1 compression ratio? Thanks.

RE: Forged Pistons/Forged Rods

I did a search on Summit Racing and came up with two sets of rods from Eagle and one from Manley that fit a 327 SBC with a 5.7" rod length that looked like they would fit. Prices ranged from $430-580- ouch. Not sure if there are better alternatives, but I would like something with an H-beam design that's fully forged.

Place called "Raceparts" sells the small journal SBC H beam rod for 289 usd for 8. Im ordering a set but 6" not 5.7"

ill be grabbing a set of forged pistons around 9 to 1 compression sometime this year but i dont think they will be the same as what your looking for.

RE: Forged Pistons/Forged Rods

I've done more searching. Forged Aluminum rods for a 3.4 pushrod engine are $564-618 from www.ftpp.net They also sell forged Ross Racing pistons for the 3.4 pushrod engine for $480-540. Not a big fan of the rods (aluminum), but the pistons may work perfectly.

Ross can also do custom pistons for a 3.4 DOHC for $480-600. CP, Arias, JE, and Wiseco will also do custom pistons, but I don't know how much they would cost. It seems that all forged pistons, forged rods, new pins, new rings, and new rod bolts would cost $1250-1500.

Forged SBC rods range from $429-579 (Eagle H beam vs Manley H beam) for a set of 8.

For a cheaper alternative, Speed Pro has a set of 3.4 DOHC pistons that are Hypereutectic with coated skirts for around $215. These are probably the way to go for 95% of the DOHC engine rebuilds.

Tim, get ahold of me on what your price range is for the forged pistons and exactly what you want to have done to them.


i have a guy locally that is making a set for me in the near future for a LOT less than what your finding prices for.

the only thing he would need is 1 stock piston and your specs.

and he can even custom make the piston to fit your choice of rods (which he sells/makes as well)

let me know.


if you want, I can PM you my phone # and we can talk about it more.

Any further info about this? I need some custom pistons as well and was wondering what has come of this...

You don't want to use aluminum rods in a street engine. There are also Crower forged SBC rods available for around $300-$350, already narrowed. They are not H-beam, but are plenty strong. They are the same ones Curtis used in his turbo engine. Figure in another $100 or so for machine work to have any of the other off-the-shelf SBC rods narrowed to fit. Any particular reason you are set on H-beam rods?

Marty

Cause H beam is better.

[RacerX11]

Better, but needed? Titanium rods are better than H-beams, so why not use them? Curtis runs his engine up to 8Krpm, pushing tons of power, all with the non-H-beam Crower rods. Other than the WOW factor of having H-beams, I don't see any advantage here.

Im just giving you a hard time man. I dont know who the hell Curtis though.

I had a look at the crower rods. very nice pieces but i couldnt find a listing for the "already narrowed" versions....do you know what part number or which page on their catalog to look on?

[RacerX11]

I know you were...I was just dishing it right back at ya I don't think they list the custom ones on the site, but several 60degv6 members have purchased these rods. Curtis = TurboZ24 ( http://www.turboz24.com/ ). I think they are the Sportsman bolt-through rods. Someone posted a picture of a tag that came with one of these rods. The PN listed was a SP93212PF.

Germ, please PM me your #. I am definitely interested in hearing more. I would like to spend the least possible of course, but $400 sounds pretty reasonable. I would like to spend under $1k on rods, pistons, rings, pins, and rod bolts. Specs- similar to stock, but with a dish/flat top for a 8.75:1 or 8.5:1 compression ratio. I was originally thinking about 9:1, but I think I want more boost than that!

The Crower rods sound very promising. If I call Crower would they know about them? They're already narrowed and a perfect fit for a stock 34? I beam forged is more than fine as long as it saves me a few hundred dollars over H beam forged- the increased strength of a H beam isn't worth that.

Thanks for the info guys. This has definitely turned into an interesting thread!

If you don't mind, please send me that info also.
