it is a shame, it was a good car. Ive been curious about front wheel drive however.

the shell is in storage for when i come across a  cheap enough m3 engine engine (euro s50/2 hybrid)

Hi

Just thought i'd update my thread.

So around 2 weeks ago. I did my last event in this 8th overall out of about 85 starters so was very happy.

But on monday after the weekend i had a guy come to look at it.

So the car has now been sold. And ive moved onto a vw golf mk2 with a 2.0 16v engine which will be getting the same treatment as the bmw had

Looks good!!

Would it be possible for you to measure how much them 90degree bend come away from the take off belt?

How aggressive cams will a standard e30 inlet be able to handle?   

Id like to copy metric mechanics rally cams. As my build is pretty much the same except i have higher compression.

So ive looked at catcams m44 cams

Catcams have:
255°/248° - 217°/209° - 10.50mm/10.00mm - 1.45mm/0.45mm
263°/256° - 225°/217° - 11.00mm/10.50mm - 1.70mm/0.70mm
306°/299° - 252°/244° - 11.45mm/10.95mm - 3.40mm/2.90mm

There is more aggressive ones but i still want to be able to drive this car 

What are peoples thoughts? MM cams are 270 and 11.5mm lift or there abouts

Engine + Driveline / Cam regrinding

« on: October 14, 2016, 03:49:48 PM »

Hi

Just looking for some info.

I cant get my head around how regrinding a cam works.

Surely if a cam is ground you will loose something somewhere.

Keep on hearing people saying theyve had cams reground to race spec at 300deg duration etc.

So if i have a standard m44 cam. 240deg 9.5/10mm lift ish?

Would it be possible to get a copy of metric mechanics rally cams which are 280deg and 11.5mm lift?  Where would the trade off be if any?

not posted on my topic for a while.

nothing much has changed to the engine, its been stripped once as it was leaking, seal between the head and rear bottom timing cover, due to the large headgasket theseal was abit to thin. so the only thing we  could think of was rhoderseal under and above the seal. (not ideal) but it has worked!!

Now I have a leak from the oil filter housing. 

Also the car is fitted with a 5.43:1 read diff. it is insanely quick!! ok it will only do around 90mph max but its all i need.

what would you guys recommend to run as spark plugs?

....have also been offered solid lifters and a set of cams.....

Will it run fine without mapping?

Ill try and hunt a e30 manifold down just checked ebay none there.

Is the e30 tb different? A guy on ebay does bigger bore ones on exchange.

I also have an 320is e90 here with the 175bhp 4 cyl engine. Not sure if inlet off that fits? Although it looks entirely different and may raise questions at scruiteneering!

Here are the regs related

4. Engines with more than one camshaft per bank of cylinders may be used providing that they  were originally fitted with fuel injection and that the fuel injection system complete  with plenum chamber and throttle body is retained unmodified.
18.3.1. Fuel injection may be fitted where it was standard equipment by  the manufacturer for that engine type and where the original plenum chamber and throttle body is retained for that engine type.

Anyway try this because the disa inlet manifold was designed to give more torque down low,  but to do that they had butterflies in the inlet manifold and not a very smooth air flow. Which starved the normal m44 of air at decent rpm! Hence it had less go in it compared to e30 m42.

Do you think changing cams is pointless?

Yes thats me

Yes that looks very good!!

Ihave looked into the m50 manifold a while back.

Not sure who i could use to modify it.

Also not sure weather regulations allow. I did ask but no answer came back to me.

If i run a different inlet without disa i will need a retune? As my mapper has made use of the disa valve and mapped it into tje main map

Itbs are out the question im afraid due to race regulations.

E36 m44 head so they are 6mm stem. Ive opted for standard valves for now.

Can always raise the bonnet/lower the engine if i will gain enough from changing it!

Currently run a e36/m44 inlet with standard ecu with a fully live mappable chip installed.

Have read about the e30 inlet but mapper suggested he gets better results as he can map the disa to take out flat spots etc.

I dont know about the valves but my engine builder will know. Ill give him a call next week at some point.

If i run e30 inlet will i need different harness and ecu?

Hi.

Currently have a fully lightened and balanced stroker m44 engine with block capable of 8000rpm.

Stock head other than being ported.

Cams are listed as 244 with10.2mm of lift.

Car is very tame. It idles like a standard car and drives like a standard car with more power.

Im considering a set of catcams as ive found a cheap set.

Which are 283 / 284 10.75 lift.

Car is soley used for competition and is still on standard inlet.

Currently at around  169bhp and 165ftlbs i think

Im thinking of fitting above cams with a bbtb. What affect am i likely to get. Will it still be as driveable? More power? Torque?
