If money was no object and you were tasked with building..
 

the most powerful and stable N/A motor and a forced inducted motor, which motor would you go with, and what components would you use? This is just a random question that I would like to hear peoples' opinions on (people with more knowledge than me).

Let's say money is no object and these are going to be your dream motors- doesn't have to mean the car will still be streetable. To stop people from just going with a BMW v12 or something, the displacement limit will be set at 4 liters.

2JZ and lots of boost!

Stupid to limit it to 4.0L displacement. You just excluded any Amercian V8, many of which can produce outstanding numbers.

I *was* going to say the LS-series engines for both, but that damn displacement limit...

Honda RA109E 72° V10 (675hp at 13000 rpm), for N/A.

BMW M13 for turbo, with about 900hp.

No one said you couldn't use F1 engines... :fullofwin:

rb26dett with gt2530 turbos, rom tuned ecu, hks headers, r1 titan exhaust

I said, "stable" . jking. tell me more about some of the V8s than please, I've heard good things about the Ls1 engine, but I have no idea about American.

hennessey venom gt??

6.2L ls9, twin garret turbochargers, fuel injected v8. pushing up to 1200hp.

i put the displacement limit because to me, it's more impressive seeing 1000 or more horses squeezed out of something less than 4 liters, than a 12 liter beast, but that's just me.

btw, you guys have only mentioned the force inducted ones, how about the N/As?

i'll play

boosted
rb26dett 2.8L stroker. call up tomei and tell them you want everything on their rb26 genesis catalog. over 600hp. 35k should do it.

not boosted
m60b40 race engine from vac motorsport. 4.0L v8 with itbs. rated well over 600hp in race form N/A. can be boosted for more power. no price listed but i bet its at least 30k

if i had unlimited resources id just build a motor from scratch. :)

It is also typically less reliable.

Anyways hands down a 911 motor ie. GT3RS for an N/A 3.8L 450hp, track proven

Even the basic 3.8 in the 997.2 carrera S is an awesome motor that has just under 400hp. Decent on gas and daily drivable, good starting point for a build I guess

for the street, youre not gona get anything better than a BMW p60b40 engine
used in the m3gtr street version, 4.0L, 493hp

Oh more RB love than I thought!

If I wanted to build a motor, yes, RB, but I'd go to Mine's. Gotta love response and pickup instead of outright power.

Buy a motor... BMW P83? 19,000RPM 900+hp.

Beyond 4.0L... Norwood's 4000hp 5.0L 4cyl drag engine that runs on nitromethane :D

4.0L limit, haha.

Such a ridiculous engine though, gotta love drags.

NSX 3.8L stroker, supercharged :)...fully built

hmm.. gonna be an idiot and build the world's first six rotor n/a motor.


fuse two 20B's together with a custom crank...

custom v8 block with 2 K20 heads..... 4.0L 500hp+ N/A easily with bolt ons....

or maybe a a 3.5L V6 from the Super GT NSX? de-restricted of course ;)

Kaase P-51 502 cubic inch V8. 800 HP, 740 lb/ft. Fully assembled and dyno tested for $14,900 US. Oh, and it's NA to boot.

Kaase P-51

I'd love to see any Skyline or Supra get 800HP for only $15K and be anywhere near as reliable.

And this is only one engine I picked. If you google for Chevy, Ford or Mopar racing engines there are literally dozens of companies and hundreds of different engine combinations to choose from.

Twin charger 7mgte.

Why settle for a piddly little 502 (8L)making only 800 horse, when you can get an 820 (13.4L) making 1800+ ? :p

Mind you, money would have to be no object because one of these bad boys is $60,000 or more

i vant that vac m60 motor in my 5er so fricken bad.

that would be my option too.

how about take one of the WRC spec engines from last year and take out the restrictor plate.

3.0L BMW V10 P83 Formula One Engine (2003 spec)

900hp@19200rpm!
