Scooby STI Engine in an e30

[fuzzy]

A misfiring E30 316i with a big bore exhaust sounds similar to a Scooby

strangely enough my m20 2.5 sounded just like a scooby engine when it was running on 5.

Dan, you bad man, i like the noise. Anyone know why they make that noise? Its a pretty agricultural reason I can assure you.

Something to do with it being a flat four boxer engine, similar to a VW Beetle?

The fireing order is similar to an in-line four, there's two pistons at TDC and two pistons at BDC.
The off-beat noise is created from unequal exhaust manifold lengths ie, the four, that join into one are not the same length. This creates uneven pressure pulses in the exhaust system, creating the off-beat noise, not disimilar to the reason a harley davidson engine (radial) makes the noise it does.
Later in the subarus' developement a turbo was developed to make more efficient use of this pulsing exhaust gas. Which had the net result of being faster spooling and more efficient but evened the exhaust system presure after the turbo and the off-beat noise was rather diminished.

Sorry, i've been outside fixing some peugeot junk, but thats essentially it. Pikey huh! I still like the burble though. Sad and childish I know. Its the passenger side manifold that is longer.

thats a bit random.

its a plastic bag for putting asbestos in and is marked with the usual asbestos warnings, get then from work for nowt. handy for catching oil and all the other fluids falling out of the car at the moment.

could you use engine and bits from a focus st or something like that??? duratech???

Why though?

2.2 Duratechs on throttle bodies with spikey cams are good for 250bhp+

how many £££'s though to get that 250bhp?

Dunno mate, you're the Ford sicko

thank you very much guys im new to e30's and very inexperienced when it comes to any major modification (engine swaps etc) . im looking for a decent horsepower car and i fancied something a bit different but i guess most things would have been done by now, at least those worth doing. i have a 318i and i would love to get some more power

if you want something that hasnt been done before in an e30, not on the zone anyway, then fit a volvo 5 pot turbo. i think someone was going to do it but gave up.

ive looked into it and the 5 pot will go onto a 960 turbo gearbox to make it RWD. the rest should be fairly straightforward and no difficult than any other swap. i think the only potential major issue being the sump/crossmember. the 960 turbo box is quite rare but you see complete cars or GB's for sale on ebay now and again.

Nice idea! these Vovlo 54 pots are pretty impresive from what i have seen. and they are getting pretty popular to!

350-400bhp can be done on stock bottom end and you can get forged bottom ends.

Volvo B230 16v turbo's are freaking awesome motors! Forged cranks and pistons, and with a few pennies thrown at it, 500bhp can be seen before you need to start o-ringing or dropping the compression. I want one in an E30 sooo badly

did you read the article in PPC magazine on the volvo 360?

what a machine!!!

Yeah it was really impresive. i hear the 2.3ltr red blocks are similar to the Cossy engines.....

I've heard rumors that cosworth were involved in the design of the head.

That 360 in PPC is awesome! There's something about the 300 series Volvos that I really like.

[Ralphead]

Chevy LS series all the way. Cheap, very torquey, light(ish), designed for rwd and no turbo to go wrong. If your'e going to cut bodywork about then it might as well be to fit something proper rather than a chocalate pistoned japanese taxi motor. They do sound damn good though.. but not as good as a v8!

Unless you fit some LS1s can be boosted to about 550bhp on stock internals, keeping their 10:1 compression ratio too. The "Volvette" has exactly that, and it's not slow...

You cannot be serious?! the Volvo 300 series was based on a seriously naff DAF design

I know it's a sick perversion and I should get help

Zetec-E turbo conversions very popular and cheap loads of rod and piston kits out there but head and manifold will be most expensive bits if you aim over 300bhp reliably.


Duratec 2.0l with just reprofiled cams about £230 is circa 200-210bhp

Throttle body kits and ecu about £1,500 for around 250bhp
for same money you can supercharge or turbo it for same money at low boost near to 300bhp on a standard engine.

2.3 tall block generally adds 15bhp, 20lb/ft to n/a figures and double when boosted on same OE internals, you can stroke upto 2.5, 2.7, 3.0l common ones. Rebuilt with steel bottom end, people
are getting 700bhp+ on pump fuel.

2.5 5 cylinder Volvo/Ford 220bhp as standard can boost upto 270bhp on original turbo. £2,000 for a GT28 turbo kit upto 375bhp and £2,500 for GT30 turbo 450bhp all on standard internals.

as a scooby owner i can see the attraction in putting the engine in a E30 but as pointed out clearence between the front chassis will be a issue, but with so many of these coming on the market very cheap (its the new RS turbo lol)
i think the running gear/engine package would work awesome in a kitcar.

my wrx wagon cost £1000 fits the dog in handles/goes like the clappers and has no rust plus it cruises nice with the auto box which as i am a old git i like.
ok the noise is a love or hate thing i guess personnaly i love it reminds me of the old alfa engines.

Good shout on the volvo turbo lumps though that would be a great conversion i have driven a turbo technics converted 960 volvo and it was a missile handled like a tank though
auto grass boy use the engines for 500bhp on stock internals and have done for ages apparently, plus added benifit of strong volvo 5 speed gearboxs, not sure how long a E30 diff or shell would last with that power though

turbo zetec another good option all parts available but i would prefer the cosworth badge

[ShakeyC]

Cosworth do a Subaru closed decked engine block and heads

Also the Toyota 3GSTE is a favourite for big power out of 4 cylinders

[GrindCulture]

I am quite a fan of the Toyota 3G motors, so much so that I'd quite like to drop one (or maybe even two ) into a Starlet.

[redsmasher]

Anyone seen Chop Shop London Garage? They put a Sub motor and running gear in a mk2 Golf. They cut the chassis legs off and fitted the Subaru legs, made a gearbox tunnel and jigged it with lasers before welding it. Made for a proper car until they murdered the bodywork.

what about a skyline lump?? or a supra lump?

2JZ setups seem fairly popular in East Asia. There was a guy on here with one in, can't remember his name, all I know is his car was blue and he smashed up a set of Azevs.
