Is it possible to rebuild my engine and add a manual tranny and make it push 300HP for around $10-12,000

well i have 2 ideas already

1: get a bavengine 328 with the performance option, chip intake exhaust, obd1 conversion...? where would that get me hp wise? (bav engine gives you 20% hp gain)

2: rebuild my 325 with high performance internals...? chip intake exhaust, and a nice ratio manual tranny...(to change the ratio's of the gears would i have to change the diff or the gears or both or?)

3: like 2 but turbo it?

or just get a damn m3

I was under the impression that only the 2.8 could be bored out to 3.1L...double check that though, I know there is plenty of info on that if you search the forum...

some of the M50(OBBI) Blocks can be bored to 3.0L much larger would most likely have to be a M52 (ODBII) Block ..

i think the best luck is had with the 92 (pre vanos) M50 blocks being bored out and tuned with M3 parts.

We have 95 RON octane gas which is the same as 87 MON octane gas. Maybe anyone has a conversion table??

bitcore will become famous soon enough bitcore will become famous soon enough
(RON+MON)/2 = AKI (Anti Knock Index) = what is listed on american gasoline pump octane ratings.

Give me a minute and I'll figure out wtf all of this means and say some stuff.
http://www.faqs.org/faqs/autos/gasoline-faq/part1/

that article may be WAYY too indepth

The RON and MON ratings are totally different, European fuel and american fuel are different, putting one in another engien can cause excess wear +knocking & pinging.

For US AKI, the ratings is dependant on both RON & MON ratings. I don't know how to answer you guy's question of what octane is needed for the euro engine and what the difference betwen american gasoline & european gasoline is.

Part 3 has an in-depth explination of what octane is and why you should choose the correct octane isntead of the highest rating at the pump, you could be messing up the entine if you use the wrong octane if it knocks just a little bit. I've always bought mnid-grade, what the label on the gas door says to put in.

I think it doesn't bother to use US gas or European gas. The whole point is to use the right octane number. E.g. Shell is a Dutch/GB company which sells gas in the US too. The gas is the same but there is only a different rating (RON or MON) on the pump at the gas station.

My opinion; just buy an M3.

On the fueling issue: http://www.btinternet.com/~madmole/R...RONMONPON.html

There is a nice little table there. For american fuel see the PON numbers. You'll notice that US rated 94 is UK rated 98... any deficiency can be adjusted with simple octane booster additive.

The euro engine would work but there may be emission issues.

Why not take a 2.8, bore and stroke it to 3.3 with some nice new internals, breathing and fueling and see how things stack up. Or how about a 3.8 V8?

<span style='color:blue'>&quot;So my BM makes me a flash bastard? Then I guess you're just keeping it real from the seat of your nova?&quot;</span>

<span style='color:gray'>&quot;...and the home of the brave..... is bravey 130bhp from a 7 litre engine? 100bhp/litre or don't bother building it!&quot;</span>

<span style='color:red'>&quot;Aaahh the UK; where every road is jammed, under construction, poorly maintained and unfairly policed, at least we don't get over-taxed for it........ HA HA HA!&quot;</span>
