s2k with nsx engine

[madella]

it sound a bit crazy but is it possible to put an nsx engine into a s2000?

[Spicey]

yep! never seen it done though!

Anything is possible with enough $$$

[flipstar]

yep i once saw a supra engine in a s2k i was in shock no justice 2 vtec but if that could happen nsx engine would be off tap

[BRU51N]

nsx's engines are mid mounted and is rear wheel drive. if u were to put it in an s2000 which is FR it just wont work.. i suppose if u did heaps of custom work you'd get it to work.

with that amount of money your better off doing another project.

i did however read up on some project conversion awhile back, the nsx was transplanted in the 99 accord coupe (in the U.S)

[datzlr]

hahahahahaha

[WhiteAP1]

yeah but what if the vtec yo' fell off the nsx engine, and u put it in the the s2000,then got the vtec from the s2000 and made it front wheel drive,and then we cruized to maccas and got like big macs and shit, and then we all just started posting stupid shit and made this forum full of useless noob questions...would it fit then, and if it did, would it beat my mates cousins WRX coz he reckons he beat a lambo on chaple st????

[aaronng]

The NSX engine is mounted traversely. That's why it fits into something like the Accord. The S2k's engine bay was designed to have the engine mounted longitudinally. So you won't be able fit the engine without needing to cut through some chassis metal.

[chicken8]

we all know chassis metal is useless anyways

i say cut it

[STI_WRX]

why? are you going to do it?



































































didnt think so

[ECU-MAN]

just coz the engine is mid mounted in nsx doesnt mean it cant be done, think beyond the sqaure,

I know its not the same but here are some pics of an eg with a ledgend engine in it.

I see custom subframes. I think the only thing EG about that is the top shell. It is even RWD! Hehe.

[ECU-MAN]

....:)......

[Mr_will]

that is tittyfarkin awesome. any more pics/info?

[Zdster]

Can one of you guys explain what we are seeing in the second picture a bit more clearly to me? I see the axles, new subframe, 'lca' but still abit confused on the setup.

Silver bit is the transmission. And that pic is of the rear (look at where the exhaust piping comes from). So this EG is a Legend-powered RWD monster.

Ah starting to get it. So the drivetrain shaft (that connects the engine to the transmission) is out of sight, somewhere above the transmission and the exhaust?

[ECU-MAN]

the tail shaft in this case would turn at engine RPM, not road speed. Its connecting the engine to the gearbox.

I dont think that that would be a real good idea for durability and reliablity, but who knows, it looks like fun :)

Is the tailshaft visable in any of the pics? Also, how can you tell that it would turn on RPM's as aposed to the road?

Because the gearbox is at the end of the tailshaft. Since the gearbox is the part that changes the rotational ratio, that means everything before the gearbox is spinning at engine RPM.

So am I correct in saying that if the gearbox is not at the end of the tailshaft then there is a box that changes the direction of the shaft (has three cogs in the box - is that what they refer to as a differential?) so that the wheels receive power?

Exactly! and the unit pictured in the EG is usually reffered to as a "Transaxle" as it has the Transmission and axle/diff in the one unit. Despite how strange it looks there are a few cars out there that are front engined, rear trans/diff, the most popular is the Corvette (some Ferrari's have them too) It is usually done for weight distribution.

You wouldnt happen to have a cutout/cross-section picture of a 'transaxle' setup would you. Having trouble trying to figure out how it all works in one box.

This is the best one I could find by doing a quick search

As you can see the tailshaft is joined directly to the rear of the engine and then goes into the front of the gearbox/differential assembly, where the power is distributed to the wheels, ill keep looking of a better pic.

are you familiar with other driveline setups? like front wheel drives etc???

I have a bit of an idea about other setups. Thanks for the lesson though :).

Found this and thought it was very interesting.

I am confused now though. Looking through that link does that mean that all front wheel drive cars are also transaxle?

[Spicey]

Yep, as they have the Transmission and axle (differential) in the one unit!

The only difference between a normal front wheel drive transaxle and the EG pictured earlier is where the unit is mounted and where the drive exits the unit.

So is the transaxle unit pictured on the eg a stock legend transmission/diff. or is that a special unit?

Since normally in a front wheel drive car the transmission bolts straight onto the engine, do you need special 'transmission mounts' to hold the unit or does the different subframe do the job?

[panda[cRx]]

there was as crx in the states with an nsx engine in the rear.

anything can be done with money. have a look on hondatech at the project gemini del sol, it has twin turbo h22a's the last time i checked (has been an ongoing project for a while)

[Spicey]

Nope, I reckon the Transaxle in the EG would be from a mid engined Porsche/VW/Ferrari thing so the drive goes at a 90 degree angle to the tailshaft (comes out the side of the unit), if it was the standard Legend transaxle the drive would be heading in the same direction as the tailshaft (out the back and front of the unit)

Think of it this way:

normal FWD -

......................Engine
Wheel-----------Transaxle---------Wheel

Normal RWD -

........................Engine
....................Transmission
............................I
............................I
............................I
............................I
............................I
............................I
............................I
Wheel----------Differential---------Wheel

That EG and Corvette (rear transaxle) -

........................Engine
............................I
............................I
............................I
............................I
............................I
............................I
............................I
............................I
Wheel----------Transaxle---------Wheel

hehe, hope this makes it clearer!? :thumbsup:

looks about as clear as mud!?

Depends. There was 1 generation of Legend that had the engine mounted longitudinally while still being FWD (transaxle was perpendicular to the crankshaft).

I get it. Does make sense to me. For those that didnt get it (and want to learn) read the link that I posted and then come back to those pics (just ignore all the dots on the left that have spaced it out).

[Zdster]

Is there any benefit to having the transaxle mounted longitudinally or otherwise other than fitting space requirements and the direction in which the drive comes out?

[Spicey]

Ah yes! like some Audis!

No real advantage to it though, thats why no manufacturers do it much anymore.

[aaronng]

^^ yeah, I guess Honda tried it once and then gave up on it, going back to traverse mounting.

[ECU-MAN]

here is a pic of inside a prelude box.

[aaronng]

Wow, those helical gears are chunkier than an S2k's!

[Zdster]

Can you run us through what we are looking at? I take it the left hand side is the transmission and the right is the 'diff.'?

[ECU-MAN]

yep,

on the left most shaft, is the input shaft. ISB bearing sits under there, then on the input shaft moving up is 1st gear, then reverse ( straight cut gear ) then 2nd gear, 3rd gear then 3/4 syncro. then 5th gear and 5th syncro and then another bearing.

then the counter shaft.

on the bottom is a bearing,then the final drive pinion gear that connects to the ring gear of the diff. then 1st gear, then reverse gear 1/2nd reverse syncro, 1way dog clutch then 2nd gear. then 3dr gear, 4th gear and 5th gear. then two bearing.

on the very bottom of the counter shaft is a thrust shim.

most right is the final drive. ( not realy called the diff. ) the ring gear is the big gear on it and under it is the 4 spider gears that is the differential ( this is the part where LSD are fitted.


infront of all the shafts is the gear selection rods and interlock mechanisms. on the top of the two most right shafts are 3 notches, these are called detents. a spring pushes a ball bearing into a slot ( from the gearbox housing ) and it lockes the gear into place

not shown in the above pic is the revers gear and revers lockout plate ( so you cant go from 5th to reverse. )

What is the purpose of the 'final drive' as apposed to the differential? Am I right in saying that a shaft runs through the middle of the differential and final drive and becomes your output shaft and therefore powering the wheels?

Pretty much, its a little more technical than a shaft running through the middle of the diff though (unless you have a welded diff or mini-spool etc).

As a vehicle turns, the inside wheel turns slower than the outside, so there needs to be something that allows one drive shaft to turn at a different speed to the other while still getting drive from the engine.

Enter, "The Differential" http://auto.howstuffworks.com/differential.htm

[Blulude98]

yeah but what if the vtec yo' fell off the nsx engine, and u put it in the the s2000,then got the vtec from the s2000 and made it front wheel drive,and then we cruized to maccas and got like big macs and shit, and then we all just started posting stupid shit and made this forum full of useless noob questions...would it fit then, and if it did, would it beat my mates cousins WRX coz he reckons he beat a lambo on chaple st????

HAHAHA!!!!!

[TECBOY]

its possible man
my brother had this done to his s2000. He still hasnt told me how much it was....i think he is embarassed to tell me. I hardly see him coz he lives in qld but i still remember how hard the car went. quite scary

[ROLLED]

why don't you get him a post up a photo of the transplant? I WOULD LOVE TO SEE IT...

[Spicey]

Bah, me for one think its good to see some originality in modifying! If you have the tools, the money and the brains to take on a project like that good on em!

This is the disappointing thing about "modifiers" nowadays, if you can't bolt it on its not considered!

Wild engine conversions are around! A few weekends ago I was a Simmons Plains helping out a mate with his track car and a young bloke turned up with an X3 Excel, canary yellow, widebody kit and huuuuugggeee rear wing. I went up to the car for a closer look and he had mid mounted a Holden 186 and converted it to rear wheel drive! Now thats ingenuity! somebody who has slaved over a welder and grinder to modify his car instead of a book filled with aftermarket parts! Dont get me wrong, I have had an EK Civic with all the bolt on stuff and currently drive an 05 Civic sedan with Teins etc, but you need to appreciate the effort that goes into these full custom cars!

[AusS2000]

I love seriously engineered mods too and have little respect for bolt ons. My dream is to mod a CRX with a mid-mount set up from an Accord or similar.

But like the poster I doubt it will ever happen. It's just dreams on paper.

[Spicey]

VVV unique, would sound pretty unreal!

http://blog.hemmings.com/index.php/2007/04/09/fernissan/

[turtleEK1]

that RWD converted EG was also boosted!! but a hella ugly bodykit...

:thumbsup: to highly engineered swaps! don't know if it works till you try!! if it wasn't for all these people trying to design mounts for different swaps, we wouldn't have 'bolt in' swaps that we have today!

i remember in Zoom years ago seeing a MX5 with a built 2JZ in it... extremely tight fit! cut into firewall and had to also remove fenders to access parts of the motor... but shit it went!

[Vinnie]

i have a poster on my wall of a '55 chev coupe with a 3000hp rolls royce merlin v12 (from a spitfire in WWII) engine in it. beat THAT for originality! :p
