318IS AIMING FOR BOUT 330BHP

[DanThe]

sorry new to this whole new thing

Id never have guessed

[Jon_Bmw]

This is a joke obviously ?

A ratch joke? Where abouts in southampton are you? I haven't seen any IS's about.

[ShepsEvo3]

I think 300BHP would certainly be a stretch... there aren't that many S14's giving that sort of power.

I'd seriously look at a Centrifugal Supercharger if you want something to feel big cc normally asperated. Drop the CR down SLIGHTLY, no lower than 9:1 and 20psi should do it... but the you may struggle to get 20psi out of the Rotrex SC.

This is by far the easier way of doing things and have the feel of a much larger capacity engine.

Saying all this... it is possible to get over 300 BHP out of a Vauxhall 20XE engine on carbs without a SC or Turbo reving to 9000 RPM, so it may not be as unobtainable as some and me thinks?

[Bob_S]

s50b30 would be a better option or a good old 2.7 m20

[stonesie]

Bear in mind that once you have this screaming engine that makes its power at 10K it will be gutless and annoying to drive on the road, also very temprimental.

Eaven the clutch will have to be bespoke because a standard unit would disintigrate before it got near 10k, i can see the gearbox not likeing those RPM's either.


Im not saying its not possible, just not worth it, if i really wanted 300bhp with no turbo i would be looking for a S52 B30/32, again not cheap but it has a healthy dose of low down grunt and wont spit the dummy out all the time.

[Turbo-Brown]

Where did this figure of 330bhp come from? Seems very specific, rather than just "around 300bhp"

[Taz]

330hp from a m42

u need to start rubbin your magic lamp mate (and i dont mean the one between your legs)

good luck anyway

Ratch is an intelligent logical guy,with a slight illness unlike this Walter
Mitty character!

The car in question is probably parked getting it's profile gasket sorted !

[Karan]

i have an iS with 300bhp

seriously though... put an s38 in, or a e39 m5 v8

[dazleeds]

sorry but with 9k in me sky rocket
i wouldnt be arsing about with an old IS engine

get yaself round the salvage auctions and find something decent to transplant in that already has the power or more

not sure what a e36/e46etc m3/m5 engine and bits would cost, but id imagine 9k would get you well on your way

why piss about with something thats likely to break easily as its been stretched beyond its limits
do it properly i say

[oakey]

Just stick an m20 in there and be done with it

[dips346]

got a lovely v10 m6 set up

[dazleeds]

got a lovely v10 m6 set up

there ya go

no messing about
drop it in pipe it up spend a few more ks and kick every mofo,s assss

Yeah the blue or should that be red sealant is out in abudance somewhere deep in southampton.

Nothing like a proper fix for an engine about to take 2.5 times as much power

Care to elaborate?

what do you need to know

[Karan]

how much u want for it, or what ure putting it in maybe./////lol

[dips346]

how much u want for it, or what ure putting it in maybe./////lol

not 100% yet but maybe if all the prices are right

[jibowski]

badboy if you find someone that can get 330bhp out of an IS he should go apply for a job at schnitzer racing as their e36 btcc cars werent even putting out that!

failing that you could get an electric supercharger kit of ebay, they've gotta be worth 250bhp without nitrous

[e30bmlover]

sorry but i couldnt resist..... is this thread a wind up or something? as mentioned before your best bet would be to drop a s50 in there or the v10 you have two hopes of getting 330bhp out of an m42, bob hope and no hope.

[bss325i]

what do you need to know

Just wondered if you were going to do another crazy conversion alog the lines of your V12 E30's?

[dips346]

should get the v12 finished first i guess

Your looking at over 9k to knock on the door of 300bhp. Well from the likes of SBD anyway!.

330 is a major ask. Billet crank, Arrow rods, forged slipper pistons. A bottom end thats going to rev to 9.5k rpm. Bigger valves, solid lifters and extensive head work. Then a decent set of tb's and mappable management. Then exhaust manifolds etc.. Not a cheap way to chase the power.

How about a eaton charger off of a Merc kompressor?

[Andyboy]

With the right mods its possible lol

No, it isn't. 183 bhp per litre!

The two litre works S42 engines in absolute full race trim gave 285 bhp - yours for around £35'000 - and you assemble it yourself.

What a shite thread.

[maxfield]

I thought it was closer to 300hp.

[treeseries]

i have to say like every1 else if thats what you wanna do go for it but you'd be better off starting with a differnet engine. zoom motorsports if they still exist will do an E36 m3 evo2 converstion for around £5000 if they source an engine or £3200 if you give them an engine to work on. that would leave you more than enough money to upgrade everything else which you will need to turn and stop.because you will NEED to turn and stop the thing and when your looking at 300bhp on a 318is standard setup wont even come close. im in the middle of sourcing parts for a e32 v12 5litre swap which i hope to turbo but we'll see what happens? but that'll be 300 bhp alone, so search for something better i'd say. most things have been done before

[pacerpete]

Zoom motorsport are no more and from what i have seen (first hand!) you definately don't want one of their conversions !

[fuzzy]

wasnt zoom one of the bad guys from the great MFREE saga?

[fuzzy]

save a lot of bother and drop a stage 3 cossie engine in for about £6000 for an instant 330bhp.

[Yaninnya]

Just forget it, mate. Last evolution of S42 in E36 (STW spec) was 310 HP (IIRC). And it was full race engine. You are dreaming.

[treeseries]

here here how did you come up with that 330bhp figure?

[fuzzy]

but without using turbo's or superchargers that sort of power isnt a realistic target.
like i said drop in a standard 204bhp cossie and about £600 will see you at your target 330bhp.the only downside is the original £6000 outlay on the conversion

[Dominitry]

Your all wasting your time replying to this, look at the facts....he has 9k to spend, but he gets an e30 318is...he wants to get it to 330bhp, but he doesn't have a clue about what needs to be done, he's just talking shit, let him find out the hard way.

your probably right but lots of people have said that about me with my conversions.a few garages didnt even bother phoning back as they said with their quotes as they also thought i was a messer.it just made me more determined to prove the doubters wrong.
regardless of anything else though spending fortunes to get a basic engine to run at its limits for big power gives no scope for anymore future power upgrades.

[78dude]

That should be possible to get that sort of power out of an M42 engine but it will cost you alot of cash. I cant see why people are so negative here. Saabs H engine, used in the old school 99,90 and 900 can you get over 500 bhp with some hefty turbo convensions. Volvos B23, used in the 240 and 940 can you reach over 530 bhp with the same mods, a hefty turbo convensions. Here where I live is an 318is E30 with a turbo and he have around 250 bhp and a 325i with a turbo who is over 500 bhp, E30 that as well!
