Uh, pics or GTFO!


....or something.

Hurry up though, this kind of jealousy is hard to maintain

Went back and edited pics and description. Check it out...

I need advice on a TKO 600 for this build. One has become available through a member on here. How do you think it will hold up at my planned power goal on the street?? I know it's rated for 600 ft/lbs and I don't want to have to baby a trans in this car. I have been known to bang a few gears...

Without digging through the whole thread, what's the power goal for this car? Not your projected first pull numbers but what are you honestly going to be happy with? Hard question to answer I know, but that's a decent chunk of change to dump on a tranny if you're just going to be putting down much higher numbers. Yeah, it'll survive some "spirited" street driving but if you plan to drive it the way I would, you're gonna have a paperweight

He wants quadruple digits, doubt a tko will last that.

a 1000hp stick car hmmm....
I like where your heads at, but your wallet sure as hell won't

A 1000hp TURBO stick car, that car is gonna be a handful. I'd have gone with an f1r or similar blower but turbos make big numbers too.

He said he wanted to make 700, not 1000. Depending on how heavy the car is the 600 might work, i dont think it'll last forever though

 

[1991notchbackLX]

I'd like to make 1000 on a dyno just to say I did it, then tune down to the 700-750 range for the street. Any thoughts on the new magnum as a possibility?

 

[90lxcoupe]

tko600 might survive a hero dyno pull. I still say viper spec t-56 is the way to fly. Not familiar with the new magnum trans you speak of

 

[GroverDill]

As stated in the PM's

My Viper spec is good but the .50 OD is useless with 3.27 gears (turbo friendly)

Talking about this?

Key Features of the New T-56 Magnum:

85mm center distance.
700 Ft. Lbs of Torque Capability!
Fully reversible 'TKO-style' OEM-grade die-cast aluminum shifter for smooth, positive shift action.
Dual 'speedo' pick ups to accommodate both electric and mechanical type speedometers.
Built-in mid-shift provisions under inspection cover for simple, pain free mid-shift conversions.
Triple cone synchronizers on gears 1-4, double cone synchronizers on gears 5-6, as well as reverse.
Accurate, smooth, high-rpm shift capabilities.

Yeah, the Magnum is Tremec's new version of the T56 with a 700 ft/lb torque rating. I think I'm just going to follow what a lot of the big number builds have done and proven to be effective, Viper Spec T56 with G Force internals and a twin disc clutch.

 

[GroverDill]

you are going to replace the internals of a viper t56?

Just wondering, whats the reasoning for the 88? A 76 or so will make the power your looking for, be lighter, a little easier to spool, less of a headache with the DP etc. Just throwing it out there.

If you read back in the thread, I originally planned on a 76mm. However, two great deals simultaneously fell into place and I ended up with a PTK hot side with T6 flange, 45mm Turbonetics WG, and TiAL 50mm BOV all for $300. The same I night I won the auction for the Y2K88 for $900 bucks with all of the upgrades like the F-trim impeller and billet backing plate.

Bada bing bada boom, you've got a kit and turbo way bigger than you wanted, but at a price you couldn't turn down. At least I have a **** ton of room to grow with the 88.

 

[1991notchbackLX]

I'm not going to, G Force is going to.

Apparently, they are rated for 1200 horsepower and 1000 ft/lbs with their mainshaft and other upgrades...

Spoke at length with the best engine builder around here today. The chinese Scat crank is going goodbye along with the solid lifter cam. A custom hydraulic roller turbo grind cam will be ground (probably by Bullet). Quadruple digit horsepower is now a reality, but not a probability, simply because I don't have the pockets deep enough for when **** goes kaboom, and it will go kaboom. The goal of ~750 horsepower for the street is retarded enough as it is. The heads will be TFS 240s and I'm going to TRY to get a super victor under this 2.5" cowl...

 

[GroverDill]

Super Vic intake and stock hood here.

 

[Shaolin Crane]

Nice call on the 240's

Super Vic intake and stock hood here.

Interesting... I'm guessing you have a Super Victor EFI? Anyone know if there's a height difference between the Super Vic EFI and carb? I'd assume there must be.
