Forged Pistons For MP3/P5

[NYCZMP3]

CHARLIEP5.....u are the man....plz keep in contact with me about the rods also...i once called crower to make the rods...tey said like 525 for a custom gorund forged rod....i wanna lower my compresssion to at least 8:1...plz keep me informed...my project will almost be install ready when this is all said and done...thanks a bunch

 

[markmurray77]

I'll be interested o depending on cost but most likely.

Hey CharlieP5, so what's up with the rods and pistions? Any word back yet?

Nothing yet, but they assured me they are working on them. Special orders like this take time. After the first set are done then they will be able to produce them faster.

I'll let you know.

ummmm, how soon?

I need to make my car run safely again

 

[slowyellowp5]

Sorry for being so late on this one but....

I DEFINATELY want rods after I finish my turbo and pistons would be very lovely

 

[LinuxRacr]

Ok guys,

Here is my delima. I have the money to buy a BEGI kit now, but I think I may have some minor engine problems that could turn major if I slap on the turbo. I think that one of my wrist pins are loose, or something like that. When driving, or reving close to 3000 RPM, I get engine clatter. It would cost be about $350-$450 in labor to get that fixed. Since they are gonna have the block open, I may as well upgrade my internals. I know that BryanPendelton has had forged pistons (9.1:1 compression) made for is probe. I need some forged pistons and rods ASAP.

Just keepin this thread alive and back to the top, charlie. Wanted to know how wiseco is coming. Any word on Pistons and rods?
Thanks....

 

[BigBlue]

Yeah it sure would be nice to get a definitive answer on this....I want to go turbo, but it's always been my desire to go forged at the same time.

I thought our transmissions were our weakest link, at least the rods can handle the STOCK horsepower

Yes, trannys are our weakest LINK, but he was talking about our "block".



I'm interested too, BUT...guys: I heard that forged rods can cause trouble on a daily driver...I think BC of vibrations or something.

Yeah, it's true, they can cause problems. They are not the same weight at stock, and they are never forged to the same standards as our factory rods. I'm hoping that the dampers can releive some of that stress.
The ideal is usually OEM forged replacements, or replacements through the racing division, but that's much more common for american cars.

the competition manual for the triumph spitfire i had said to take the rods out, have them shot-peened to relived the internal stresses, polish the outside, and have them balanced. this could probably work with our rods. what do you think?

side note: the factory triumph spitfires that competed at le mans were rated at over 130hp out of a little 1200cc motor, and ran at an average speed for the race of 120mph. none of the motors grenaded, and of the three cars that entered, two finished in the tops of the class. i believe the third crashed out half way through the race.

could help. However our rods are already internally balanced and polished. I'm not sure of the polishing method used, but they are polished. I wonder if the shot-peening would help any?

 

[njaremka]

well, it was just a thought. i have never seen the internals of a modern engine, let alone the FS mazda engines. i suspect they are built well, though.

the old spitfire engines ahd horrible tolerance levels. the rods looked like something you would stick in your lawn mower, what with all the casting flash left on them. you could almost reduce the weight by 1/3 by removing all the casting marks and polishing. don't even get me started on the crank!

I know what you mean by the 1.5L spitfire motors god they were aweful. I'm planning on making another spitty now but with a Nissan SR20DET!!!!! imagine 205 hp in a 1700 lbs car

well, we are getting WAY off topic now, but: if you think 205 is a lot, check this out:

[markmurray77]

Just trying to keep this alive, and maybe on topic

 

[TightMP3]

There is a guy that is checking on the forged pistons and rods for me also. Its looking around 1500 dollars, Nothing in stone*** I would like to see how your hookup is going. thanks!

 

[MacProtege5]

any news on the forged pistons?

any news? i would really like to get these forged pistons in 8.5:1 compression

 

[BryanPendleton]

I'm currently working with Wiseco Pistons on the creation of a Forged Piston Set for our cars. Since this is a special order I can ask them for a discount.

Are you guys interested?
They told me once the pistons are made they could provide me with any compression I want.

They already have the stock P5 Piston. All I need now is the Head Compession CCs. Anybody know what it is?

My FS head on my 96 Probe with Ferrea valves and polished combustion chamber has a head volume of 38cc.

Ferrera valves have a thicker head (ie. takes up more head volume). Polishing of combustion chamber increase head volume some. . . . so stock head volume is probably in the neighborhood, but you will need to check your own head with the valves you have.
