Out with The P-1SC In with the Twin Turbos

[NXSVTCOBRA]

Do you have billet rods or forged? If you have forged, don't expect them to last very long at those power levels.

give me a break, 700-800 hp he should be fine using 4340 stuff, billets are nice, but are they really worth the extra thousand dollars for the rods alone? there are thousands of cars running high hp with 4340 stuff, i know of one personally, my close friends' 93 coupe 855rwhp using e-bay 4340 rods, they aren't even name brand......

:nonono:

5.0/5.8 cars are completely different than a 4.6. The don't run the revs and they have more displacement (and more most, less stroke, which makes a big deal), so at similiar power levels the Modular goes through much more stress. Billet's are rarely needed on the pushrods.

I wouldn't trust ANY 4340 stuff at that level, not for any amount of time. Yes, there ARE cars out there with those internals, but there are also 500rwhp cars with the stock powdered metal rods. Smart? Strong? Reliable? Nope!

I have a good set of Eagle, Manley, and Modmax rods in my shop that have failed; some in 03/04 Cobra, some in forged rebuilds. Bent, broken, twisted, you name it. It happens- these AREN'T bullet proof like everyone thinks. Above 600-650rwhp, I wouldn't trust ANY 4340 rod, no way, no how. Not in a Modular. Those are SERIOUS power levels, and half assed internals aren't going to cut it.

And the billets are only about $600 more.

Though yes, I agree, $2000 is too cheap for internals.

Internals 2k...Well Im getting discounts, since my freinds work for Ford West..

Either way money isnt going to be an issue on this project.. Please dont post anything that doesnt apply to question...

Since Im taking my sweet time on this.. It will be done right by my 2 Master Techs with over 20 years in the buisness..

Billets will be added.. Not worth risking going forged..

I'm a machinist and get all my parts at cost and labor for free, and $2k is still just a drop in the bucket.

Hope you got $20k laying around (at least), as thats probably the minimum it'll be when it's all said and done!

Well 10k for turbos let alone fuel system upgrade another 2k..yeah its heading toward 20k.. I try not to keep track of that..

Its not Healthy, counting all that money that is spent on this project..

sorry to rain on your parade but you better up the cost of internals, good rods/pistons are gonna ruin you around $1k, add in machine work (bore, hone, align-hone, deck the block) if you're gonna do it right..... thats about another $500-$800, new head and main studs or bolts, roughly $300, new oil pump (its recommendable that you change it), new rod and main bearings.. the list goes on, and thats all considering you do the work yourself......

With 4.10's, I think you'll be in 2nd before the turbos are even at full spool. A numerically lower gear will give you the load you need to let the turbos do the work, versus the gears. A 3.55 will keep your tires from blowing off, too.

Good Info Guys..

Thanks For all The Input...

:burn:

Cant Wait...

Go with the 3:55's, anything else and it'll be a roast fest.

There's a reason most Supra owners swap out their twin turbo set-ups for a single....

Yes, because the stock twin turbos suck ass and a real twin system for Supras is a lot more expensive than a single. A single is also easier to set up on an inline motor.

 

[wolfsburg2]

the reason is the stock twins can't flow enough for big hp. and a simple set-up is usually better than a complicated one. With the advances made in recent years as far as turbo efficiency you can really have the best of both worlds with a single set-up(spool and top end).

The stock twins also have a tendancy to burn out at high boost from what I've heard.

3.27s are better for turbos

Jdk my bad..

I dont know how to post pics here..

Thats why I put that link...

:shrug:

 

[Tremor]

3.27s are better for turbos

Not to sure about that...Ive seen 3:55, and 3:73 setups running in the 9's..

But it all depends on your setup..

Anyone else have ..any Turbo Pics they want to Post..
