U can get 200bhp out of a 2.5 M20!

[Simon13]

Racing Dynamics did it, but what a top end belter they would have been. Thats all!

So i take it back, u can get 200bhp out of a 2.5.

Bet the conversion was not cheap though!

[Karan]

racing dynamics.... when only the best will do!!!

if only they made more of these cars... and their parts were marketed better in the uk!

[Simon13]

yup, so true *even more extreme than Hartge!

2.5 spec

-6 branch, plus full stainless system, with X pipe factor!
-thicker head gasket to increase comp ratio by 0.3:1. Compression Ratio was 10.2:1
-ECU
-spikey cam
-heavily re-worked head, gas flowed the lot, re shaping of the chambers!
-bigger valves

BHP - 204@6000RPM
TORQUE - 262Nm@4800 (how do u convert this to old money? Pounds man!)

0-60- 7.3 secs, i bet it was faster than this!
Top speed - 231Km/h

-thicker head gasket to increase comp ratio by 0.3:1. Compression Ratio was 10.2:1

doesnt a thicker head gasket reduce the compression ratio as per the cheap fix for turbo conversions?

[zaust]

Yep they must have shaved the head and used adjustable cam pulley
thus increasing comp and not throwing the timing out..

[Kos]

bbr used to get 235bhp from a 2.5, and mk motor sport had a 3.0 m20 producing 225bhp with standard head and cam, and 260 with head and cam.

Same thought, only reason i can think of for this is to stop it pinking if they were using the same injectors as i have heard that they are only barely good enough to supply enough fuel for the standard 171bhp, let alone 200bhp.

[Simon13]

injectors are good for 220bhp, so i'm not sure about that.

Sorry doesn't say the gasket is thicker at all! Probably thinner or they skim the heads a bit

[A1BMW325iSport]

i'd love a racing dynamics engine

[Simon13]

i've got a boot badge thats about it

i want one of their rocker covers

I cant remember the guys name, but a couple years back when we did the E30 Rockingham birthday thing, there was a guy there with his E30 Sport with a 2.6 engine. Its been featured before, but that pushed out something like 238 BHP. His manifold was a racing dynamics one...looked awesome.

Why cant some one buy one, take all the relevant readings then take it back get a refund and make some replicas up in S/S?

Id buy one...even without a E30!!

Your thinking of Cliff i believe, with a Red Mtech II kitted car. He broke the car up and sold the parts on... I'm sure someone here has the exhaust manifold, it is a work of art!

[Geoff]

Spot on!! Thats the fella. Must ahve fallen on hard times to break a car / engine like that. We've all been there i suppose.

He broke the car up so other people couldn't enjoy his hard work... it was worth more in parts than complete aswell... he used the money to buy a M3 !!!

that manifold is just a beauty. just cant stop looking at it.

[pacerpete]

I've got a nasty racing dynamics K38 e34 in my garden, it is an offensive turd with a bad taste council body kit and the ugliest wood steering wheel you have ever seen but the rocker cover and 6 branch look cool ! best of all it was Ԛ£150 !

Dibs on the engine mate if you decide to sell it

[pacerpete]

Andy i only collected the turd a week or so ago, and had to spend a bit of time getting it up and running, the technical way of deducing whether it had the proper 3.8 in it was to have a 'race' with a standard 535 i have , but alas no drive on the RD car ! . So further investigation is needed, it does sound nice and the 6 branch and rocker cover are very horny !.

[Andy335Touring]

Shame about the (auto box ?) lack of drive

[oguz327]

would this fit an RHD e30?

[Simon13]

dude thats just a link for german ebay

so another manifold exists!

[Andy335Touring]

That link doesn't go to an auction page ?

[oguz327]

May be a bit off topic, its a Hatge manifold
8029290079 german ebay.
seem quite cheep at the moment if it fits

[stevetigger]

This link should work!
