200hp naturally aspirated. Is it possible?

[Replica]

Well, if it makes that much power I might have to do a stroker. Sounds like a fun project. I always wanted to do a stroked B20...

 

[Mr. Win]

the idle is what im taking about haha thats alot of power for a stock crank i dunno about that you gonnat have to have the bottom end out anyways just do it riht the first time rather the snappin it and having more then a crank to replace.

 

[Replica]

The lopey idle can be covered by raising the rpm of the idle. I have no idea how you'd brake a crank, that'd be insane. To make 200whp with an FS-DE I assume you'd need some mean rod bearings to rev high enough to make that power...only time and money will tell. Even with 200whp the car might run low 14's....

 

[Mr. Win]

it looks something like this yea i meant the rod bearing hah more expensive then just buying it al the first time. i hope it works out. what would your powerband look like on this motor?

 

[2k2silvermp5]

I think 200 whp should not be a problem but you may spend alot of money doing it though. Wagner motorsports and perf works together are working on some cams, use a stand alone engine management syste, have the heads flowed and thoroughly ported and have some custom high compression pistons made.

 

[PR5Matt]

Even with a high compression stroker, I don't think you'll see 200whp. The FS-DE head flows like ass....(sssh)

Do you have any flow numbers?

 

[twilightprotege]

it doesnt flow that badly...but needs porting.

buy matty - 2.4L - you do realise that even with 86mm pistons (absolute block limit) you'll need a 103mm stoke...i hope to god you're talking about an engine swap (i assume you are)...and only 10.1:1?

 

[Turbo Matty P]

2.4L is my original plan based on what I saw with the SRT-4 motor. They did a long stroke on it and it turned out pretty damn nice. I was only using 2.4L as an idea. 2.3L is fine also and I know it's possible. Also, the compression was kept somewhat low as I mentioned wanting to run some squeeze "nawz to the ricers" on the motor.

I'm getting the cams from Perfworks, and I'm going to work with Andy about the shortblock once I get the AEM paid for. All this performance is nice, but I see the stock tranny being a very limiting factor. I wonder how long that open diff will hold up to massive burnouts.

*edit* the stock crank is forged already.

 

[twilightprotege]

yep, the stock crank is forged which is a good thing (just knife edge as much as you can afford), but on our engine you're really best of just boring it out to the block's limit of 86mm....imo ofcourse.

 

[Turbo Matty P]

I'll talk to some of my old hotrod buddies and put together some numbers, then I'll talk with JE or Weisco about some pistons and rods. Imagine getting forged AND stroked at the same time. I'd feel much more comfortable pounding the motor then. Nothing says "piss off" like 2.4L, 11:1cr, 75hp shot and drag radials.

 

[Replica]

Do you have any flow numbers?

Nope, 2.0L motor making 130hp? Not much to think about...
Just like a B20....bad head.

 

[twilightprotege]

so you're definately going to keep the fsde? dont forget also that the stroke (just like the bore) will be limited to what the block can take otherwise you'll need block machining to the entire bottom half, not to mention spacers on top of the block because of the increased travel, adding to the cylinder walls below where they currently go to....it wont be easy in any way at all. you're honestly better off swapping to the 2.3L outta the 6/3 then playing

 

[Turbo Matty P]

I already have a 2.3L from a mazda 6 and it is an ENTIRELY different beast. For starters the head is backwards (intake in front exhaust in back). This may only be a factor for using a stock 2.3L head, but I do not have any way of verifying that the 2.0L head will bolt onto the 2.3L block. Also can anyone confirm the tranny code between the P5 and the M3?? If they are the same tranny then it should bolt right up....maybe there is something to this 2.3L block idea...

 

[Mike R]

Matty, isn't the 2.3 in the 3/6 the Ford duratec? Thats a tough motor (as been discussed on TF many times)

 

[hi-perf]

nope different trannys i remebmer

G15M-R and G35M-R

i doubt that a 2.3 in the 3rd gen is attainable from an economical standpoint

like twilight said ive been calculating a few things and the best you can do is like around 2.15L when bored out to the max with the stock 92mm stroke.

im going to go all out high end horsepower with my destroked 1.8L, im thinking of going 86mm x 85mm, should yeild 1929cc, when coupled with a crank pulley, 4-1 header, and some smart cams should be a nice kick in the pants up high.

 

[Notorious]

200whp on N/A is gonna be lot of fun. I love the feeling of a highly tuned N/A motor. Even more than a turbo motor.

 

[twilightprotege]

the head on the 2.3 wont be interchangeable with the fsde. different size bores

and yeah matty dont forget the fsde is already a stroked out engine....the 1.8 is what it was originally

 

[jonlong]

So it sounds like a lot of involved work to attain 200hp n/a. Do you guys think it would be cheaper to get a turbo kit? And with a turbo pushing about 6 or 7 lbs of boost (200whp), do you think it would be detrimental to the car or would it still drive fine. I've heard of people who have done custom turbo installs who have problems, but i'm looking at a complete kit (hiboost, wagner motorsports, essentialspeed).

 

[twilightprotege]

personally i'm going NA because you can build the engine up little by little and it's much easier to tune.

and a little bit because everyone goes turbo...i'm not like everyone

 

[hi-perf]

yep i aborted my turbo operation because of money.

i didnt have enough to throw every goodie i wanted on it, so i sold it and im getting some nice n/a stuff and will slowly build the car up.
