Utopian Drivetrain
 

So I've been wondering for a while what the best engine and/or trans. setup would be based on hp and tq potential (and where they are in the power band), responsiveness, reliability, and such. Basically, if you weren't restricted by money, time, or space what engine would you be rockin'? One restriction: it has to be a production engine...otherwise we'd all say an old school F1 engine running 50psi. And one other thing, I guess I should specify that it would be for road racing and not drag, although if you want to list some good drag engines go ahead.

Turbo KL-DE with T5 trans.

Judd V8 with straigh-cut sequential dogbox. If that's not production enough, built LSx with afore mentioned tranny.

2JZ-GTE. Getrag 6 speed.

Maytag horizontally opposed twin from the random picture thread and a sequential gearbox from a KZ125.

BMW S85 V10 with the new 7 speed DSG transmission

Whatever engine that was in Airwolf.

20B 3-rotor with 6spd trans from Japanloand FD RX-7 to a 3.63 r&p w/OSG LSD.

8.4 viper v10 w/ t56

Bored and Stroked 2.5 MZR with Cosworth cyl head, giganticam, and IRTBs.

What ever transmission and rearend that would hold up to an all out N/A MZR.

Maybe nitrous. :nxsmile:

In the miata right? All aluminum LS v8 motor with some badass heads and valvetrain, sequential gearbox, tru-trac or whatever diff is similar to a Torsen but can handle the power. Torque baby.

Normally aspirated, high compression, high rev, bigger cube, wide powerband, light small lump tucked lower and further back. Could be 4 or 6 holes with this car without making it too unbalanced.

4 wheel drive. Two LS motors. One front mount. One rear mount. Single 100mm turbo for both motors. Or something like that.

A decent v6 with a weak/low quality 5-speed? In a dream thread? I know you can dream wilder than that.

YES

Or: One of those busa v8 jobs, punched out to 3.2L. Do a bunch of porting and bullshit and make the redline sky-high (like 13-14k). Staged shower injectors above the velocity stacks. Keep the bike trans for sequential action, with a button on the dash you press for reverse.

^If that isn't production enough, turbo busa motor, punched to 1.6L. same shit.

Run a shaft off of where the chain drive would go. Rear end something with an OS giken something.

THIS^^^

But custom fab housings and whatever else I could out of titanium.
Also a boost for good measure.

lolwut?

imaginary tranny is imaginary? Or did you mean like an aftermarket dog-box?

Pratt and Whitney F119-PW-100 turbofan.

So a miata with one large trailer to house the engine, and another one for fuel?

Ford Racing 427 Boss (500/500 in NA config), T-56 w/GM F-body gearing (4th = 1:1, 5th = 0.75, 6th = 0.50), '99 Cobra 8.8 IRS Torsen w/ final drive to match final HP/TQ numbers....



...then write Corky a blank check to "improve" things!

+1 on this 600 reliable whp and 600fbtq at 2500+ rpm only weighing 100lbs more than stock.

Fuck you I will take a F-1 out of a Saturn V and shit all over your pissant P&W.

T56 is a terrible transmission.

You're high.

EDIT: and Canadian

EDIT x2: and have a stupidcharger.

This is my dream thread, let me enjoy it.

Please enlighten us.

Have you driven one? They shift like dogshit. :facepalm: I drove an LS1 FD w/ T56 a few years ago and it felt so slow and clunky compared to my stock FD Mazda trans.

You say it like I am embarrassed about it.. or an insult? lol...

Yeah I have, believe it or not. There is one 20 feet behind me. It works fine. The other one (that is near double stock power and torque) works fine too. The others that I have driven (1000whp turbo cars) work fine as well.

Leave my dream alone.

Ok. BTW, never said they didn't work. Just better boxes out there for a dream thread...

You drove a poorly swapped car, that does not speak for every one ever made.

That's for you to decide.

Holy shit, dude. Just quite.

It's smooth enough to be used on a TON of cars from Z06 vettes, to cobras, to ever single viper starting from 1992.

It's a great trans and I have driven a lot of them. I have not encountered one yet that I would not pick over my current miata trans or any other miata trans I have driven.

8.4 viper v10 w/ t56 = My dream miata drive train.

It wasn't poorly swapped.

Yeah it was. I was there.

I get it. You like it! I don't. The world wouldn't be the same if we all agreed all the time. Hardly any salt.. but thanks for trying.

Have fun on your one man island ;)

You're the only person I have ever heard complain about the T56, then again you did drive a poorly swapped car that probably had a beat to death LS T56 and not the buttery smooth, superior viper T56.

So I just noticed, you have not listed your dream drive train. Contribute to the thread, please.

An "LSx" from the Pratt and Miller Corvette C6RS, it's punched out to 8.2 liters and sounds like fucking thundersex.(hear it here) For the trans, I'd just go T56.

I'd also like to try out a Mopar 360c.i. V8 in a miata. It's a OHV engine like the ford 5.0 and chevy LSx so I think it would fit.

My dream drivetrain has already been posted. N/A peripheral ported 20B w/ Quaife gearset in stock box, although stock gears would handle the power just fine. Easy 400+whp that revs like a formula car.

I always wanted to make a custom frame for a kelmark GT and put that very drivetrain in it...

Wow. 'Lotta different ideas. I thought there would be a few different engines with followers fighting for their engine god. I was thinking something like a modern NASCAR engine (with injectors instead of carbs) because its got a load of power and I would think its relatively pretty responsive. Thats for a surgical track weapon. I'd go with a Merlin V12 from a P-51 if I was going for badassery.

When I'm bored with the Miata/done with it, I am going to buy another FD shell and do a 20b, although more likely than not just a street port with ITB's. 350whp for a weekend car is more than enough.

Aspirated peripheral port 26b with a sequential dogbox.

Twin turbo 1uzfe w/ ITBs and a built r154. Ford 8.8 diff.

Honestly I never looked into it. Sometime years back I saw something with a 98-02 RX-7 in Japanland with a 6spd in it. But I just did a quick skim of the web and I'm guessing I saw something a little out of the norm that time awhile back. Maybe it was a Getrag ot BW or Tremec unit.

Either way, a 20B + 6spd would be what I'd go with.

Yeah having been in the rx7 scene and owned an fd, I'm pretty confident that there is no
Factory 6spd.

I don't know about "terrible" but they can't handle street tire wheel hop on a Viper running 6psi. I helped pick up a bunch of large pieces of the tail housing at the track down at Bradenton Motorsports Park one afternoon. It was said by others there that it was no big deal because Vipers shit drivetrain parts all the time.:dunno:

There's a pretty active thread on rx7club right now about a partial pport engine a shop made (Definedautoworks) with staged butterflies on the p-ports mated to a stock intake, and a whole bunch of badassery that dyno'd over 420RWHP at around 10k rpm.

That is THE 20b for me

Well no shit that it would make over 400...p-ports! (the best sounding ports). I know Rick Engman made a little over 340 @ flywheel with a stock 20B deturbo'd and with a custom exhaust manifold and tuning on his engine dyno. I would imagine that a 20B with S5 rotors, better intake and mild porting would be damn near 400hp. At the point at which I can afford a 20B swap, it would have a full p-port...and be turbo.

LS9 with a set of ported heads and a smaller pulley. The trans would have to be a TR6060 and a 7.5 rear end with 3.27 gears and a trutrac.

The T56 is not a bad transmission once built, but they do have flaws out of the box. Paper frictions and stamped keys come to mind. I eventually have to pull mind down and replace those before it gets locked in 3rd, 4th, or reverse (yes, I've had them stuck in ALL those gears before)

Gorden monsen on rx7club has a street ported 20b with s5 rotors and a stoke intake lim/uim and iirc made 375whp at like 8700rpm. After dabbling with turbo rotaries for quite some time I think that n/a is the way to go for reliability.
