Which Conversion???

[bigjon]

Hello everyone, Just for starters im new to the site and have a e30 325! I want to put a different engine in it for track, 1/4 mile and the occasional weekend thrash. Just wondering if anyone has any ideas on what they have done or something new? I dont really no where to start researching so any help or information would be appreciated. All i know is that i want BIG power!

Tune what youve got?

Manifold/exhaust
Chip
Filter
Cam
2.7 Block?
Change diff

All make for a good track car!

what do you consider big power?

[bigjon]

Big power is prob 300 ish maybe

[Ant]

S series engine swop or Turbo then fella

M50 with all the toys will not top 240 HP

M20 with standalone, Tb's and a 2.8 stroker conversion is c 260hp

M50/20 Turbo- 3-400 HP if you use the right turbo

[charlE30]

M30 turbo just like Toby's

Oh and welcome to the zone, I see your in warwick to

[fuzzy]

dont forget the ford cosworth turbo.....300bhp is just the beginning

[m-dtech]

m50 turbo or supercharged

m50 2.5 = 200bhp out of the box !

[Turbo-Brown]

Yeah, turbos all the way

Note how I say turbos

[m-dtech]

hehe, mmmm TRI-TURBO m20

[Turbo-Brown]

sure someone'll do it.

Got a piccy in a book of a tripple turbo E-Type!

I'm waiting to see if someone does a twincharged straight six, i.e. an overdriven supercharger at low revs then a whopping great turbo kicking in at higher revs. Chargecooling, NOS or methanol injection would be quality too.

Maybe you're the one to do it Bigjon. You'd get (as you say) BIG power, but if done well you shouldn't have BIG turbo lag. It would be a BIG job and would probably require BIG bucks if done professionally. You would certainly end up with a BIG thread and loads of advice etc. if you put the snaps on the zone though.

Go on, twincharge it for the likes of me to gawp at and ask stupid questions about it.

[Turbo-Brown]

Well, I can tick the Charge cooled and no lag (hopefully) boxes.

[tim-ix]

Is your set-up sequential with one little and one big turbo or a straight twin-turbo set-up Turbo-Brown? How do you get around the inertia of the turbos if you open the throttle wide at lowish revs?

I've always liked the twincharger idea, a la Lancia S4 and I reckon some of the more modern Japanese specials like the Mitsu Evo FG-400 would really benefit from the set-up. A guy from the Ford specialists Power Engineering did a particularly good looking installation in a Mk1 Fiesta a few years back and I'm sure there are other home-brewed specials around as the really tricky part of switching between the chargers is made easier with programmable engine management.

LS1 V8 !

There we go.... forget all this straight 6 nonsense

Anyone ever seen a Scooby flat 4 or Mitsubishi Evo transplant into E30? I know the mitsubishi engine is transverse in it's native environment but it can't be <i>that</i> hard. I guess there might be room to put it in the E30 in that orientation and keep the gearbox. I doubt 325ix hubs are easy to find though

Why does nobody use these engines, there must be loads of stacked doner cars in the breakers yards?

[snoops]

do an s50 conversion or twin turbo

scoob flat four might be difficult due to its shape.

The current setup is a twin parallel with both chargers doing the same thing.

The setup I'm working on is to be a sequential with a little blower and a great big one.

Inertia of the small turbo shouldn't be an issue as it'll have 2.8 litres puffing at it and it really is small! Of course there will be a lag, but it'll be tiny.

The larger turbos only gets exhaust gas which isn't being used to generate boost by the smaller one so by and large I should have at least 1bar available at any engine speed

[tim-ix]

The sequential set-up you're working on sounds interesting. I'm sure it'll take lots of time and effort to get it right but if you can get a smooth transition between the turbos you should end up with something really effective.

Mounting a Subaru motor would be very difficult indeed. Earlier Evos had longitudinal engines I think, so transmission bits might not be impossible. I can confirm that iX bits are a PITA to get hold of and usually expensive to boot.

[Turbo-Brown]

Yeah, I think the control strategy is going to be the trickiest bit to sort out, but with a computer controlling the whole thing, there's lots of room for trial and error

[bigjon]

cheers guys!!!! so many ideas to go away and think about but i like the sound of twincharge!!!

I think its called a compound charger?

You are quite possibly right Geoff. I don't know who the first people were to combine a supercharger with a turbo, but Lancia did it at least 20 years ago now. I don't know what they called their system, but it all comes to the same thing really, lots and lots of pipework and lots and lots of power.

[stonesie]

The origional name for it is compound charging, but VW have launched it in the new golf and re-branded the same thing 'twincharging'.


Everybody forgets the lowly micra though.... March super-turbo, 930cc and over 100bhp 20-odd years ago, and they can be tuned to 180bhp on standard SC and internals.... proof that the system works.
