NA Power??

[dmelvi007]

How much power can you squeeze out of a B230F, I am just curious. Currently I have a K cam and some sort of crappy CAI. Port & polish, headers, real CAI, underdrive pully? This kinda sounds like an interesting challenge, I'm shootin' for 120 RWHP. Is it doable?

I saw a B230F on a Norsk furom a few weeks back.
What was it, 238HP, for $7000?
Yeah, somewhere thereabouts.
Speed costs. How much you got?
If you want teh real hookup 2 feed yur addicshun, call JVAB, cuz heez got the DOPE @$$ shizzzle!



No, I have not been drinking.
Much...

[stylngle2003]

towery made 122whp/136wtq with a k cam, untouched head, untouched manifold, 2.5" catless side-exit, and a 740 intercooler pipe as his intake...no filter. with headwork and compression you could easily make more

ITBs?

ASSuming a healthy engine and K-jet, a stock B23E more or less. 140Hp stock, figure drivetrain loss at whatever. Done. MS&S and a proper tune might squeeze a bit more out of the stock manifolds and head and improve response.

Put a 16V in it if you want a little more power without touching the head. This is not terribly easy or cheap.

Megasquirt can only manage what the motor asks for, it can't change compression, camshaft lift, rate and timing, or exhaust scavenging.
You want INCREASES in power something mechanical has to change.
Compression, camshaft "carburation" and exhaust best order of return.

True. But we *know* that a mostly stock b230f will make 120whp on MS.

From there its just cubic dollars really. I think 130whp with a header and maybe a thinner HG is do able, after that shell out for sooooper bitchin stuff or the stuff from jonathon. A sane person would have to ask why spend all the money for an awesome bottom end and keep it NA (n/a if being used as a rally car).

[Ruben]

$500 for a descent job on you 8v head, K/H or other good cam maybe not OEM, better/bigger exhaust/headers, maybe twin carbs(easier and cheaper than MS) I think 160-180 isn't impossible at all.
Foggy James had something like 140 with his r sport like kit on the b200k, that's only a cam and carbs....

I was just going off the fact that the stock ignition timing is really conservative, and bumping it up a bit can probably give dmelvi the slight power gains he's looking for.
That and Towery did exactly that.

Okay so yu are the guy to talk to, lets talk street legla exhaust. Don't worry about emissions.....

check your state laws. if you can be cited for not having a cat, get a cat, or a make something up that looks like one, with straight pipe going thru. Otherwise, a couple straight thru mufflers and a tip will quiet you down nicely as far as any noise goes.

In washingtonia, if your hooptie is 25 years or older, there are no exhaust regulations.

*happy dance* 81 FTW.

There is nothing special about the B23E block, other than not having a knock sensor installed. It is the same as an automatic B23F with flat tops.
It is the cam, ignition curve, intake manifold and head that you want from the B23E as well as the turbo fuel dizzy in k-jet land. So, you'd really mostly want the cam, head and inlet manifold if using MS&S. A B23F (preferably flat top piston one from an automagic) bottom would work just fine with all of that. Or a B230...if you like those.

take a VX or a V cam, this gives you little bit more than 120hp, a 531 head with a VX cam gives you 136hp, a 531 head with a V cam 140hp, 531 and V cam catless gives you 150hp - all stock pieces :-)

[towerymt]

slap a 16v head on there, add a liberal dosing of megasquirt and enjoy. It's enough for 140whp with a crappy tune... sky's the limit if you know what you're doing. I am having bad thoughts about my 740...real bad thoughts...

I live in Seattle, u-district, but the car is registered in Whatcom County!! No Emissions FTW.

Where would on find a 531 head?

in Europe every 940 B230FB with 131hp has a 531 head, incl. my car. The earlyer B230ET's with 182hp where also equipt with this head (and sometimes with a 405, but i'm not sure) and in the states you can find this head also on some Volvo Penta boot engines.

Searched through my bookmarks, here we go:
http://wwwrsphysse.anu.edu.au/~amh11...ad_531_530.htm

If you want a engine which has still good power at low end then take the enem V15 cam or the volvo V cam, or the VX3 (in this order), you can find the V cam on B200E or B230E engines, the VX3 comes with the 531 head. The VX (without the 3) is a sport cam here in europe, but volvo sales it no more. With all cams it is no problem passing any emission test. If you can find a 531 and combine it with the enem V15 you are at the same level with a 16V B234F. And that's not really a lot of work, isn't it?

I don't know the K cam (earlyer Carb. cam?), the A cam is turbo cam (e.g B230ET) and with both of this cams it is not easy to pass the emission tests in europe, so that's the reason why these cams are in europe not so popular.
