I'm making one from an H reg 325i. My mate francisb has already got one. Both will (eventually) have e36 M3 engines.

If anyone else has done a project like this, please get in touch as I'm lightening it at the moment... plexiglass and grp bits is the plan. Suppliers, bits for sale, things to avoid?

Interior is pretty much stripped, including the bitumen sound insulation. You b4stard Francis, I removed it all with a hairdrier and white spirit, then weighed it. I saved 8kgs for about 20 hours mind-numbing work...

Then even worse, I see yours and you've left half of it in.

I'll notify a guy on the e30zone of this thread. His names Ian, and he has a very nice e36 m3 engined 332i.

Wasn't cheap though! lol

I wander onto the e30zone occasionally (mainly selling the bits I've ripped out of my car!) but not the main forums. Any intros would be useful, cheers

Hi Ian,

I basically know about the installation - manual pedal box, different sump pan etc. (presume this is how you've done it?). I am planning on running 300bhp through the existing 325i box, then to a 3.9lsd diff. What do you think of the ratios with the E36 M3 engine? Any idea of engine speeds vs road speed in different gears? Can the driveshafts etc take it?

Also, I am going to upgrade the brakes to wilwoods and dump the 15s so that bigger brakes will fit. Are you running on standard brakes or have you found a good aftermarket big brake kit?

Finally, I am going for lexan windows, grp bonnet and a few other lightweight mods... any decent suppliers or prices for these? Good websites etc.?

Any info much appreciated.

All the best,
Dom

Dom for tyre choice reasons you might want to keep to 15" wheels as tyres- esp track tyres, are considerably cheaper in 15"

Its still in development mode ATM but this Porker based kit for my Golfy trackslag might work well on the E30, certainly stops the Golfy rather well anyway.




or if you use one type of 15" wheel= compomotive MO, they can allow the use of the Seat bigger Brembo set up with 305mm discs.


Either way I guess there is no rush as im sure it will be a good few yrs before yet another domster project hits the track anyway......

LOL, yes, it will be a normal 'overnight' completion for this beast as well as the Ult

I like the big brembo set up; will get Andy to advise. Yours look good. I was considering Willwoods with 320mm(?) discs (about 600 GBP for the front kit, IIRC), but these aren't 15 inch compatible. Therefore, I have got a set of 17s as the price for 17 inch tyres is pretty good these days. Plus the 17s are more blinging, aiiiii.

Needless to say, I look forward to meeting the Iguana Racing Vehicle on a track day when the E30 slag is complete. You can even have a go at the GT3s in it

Well other than I know I'll be an OAP before this ever happens I'll look forward to it

The only thing I always say to be aware of with big brake convs, is the price of replacement discs/pads.

Some replacement disc costs for some are stupid, whereas for this example its £35 from VW for discs & £45 on pads from Porsche lovely jubbly

So while this set up might not be what you are after even somat that used say a Porsche big fecker set up could cost as low as say £65 discs £45 pads!

Use the E34 5 series sump pan, as in the E30 the engine sits over the front cross member and the E36 ones sit behind -this will mean you'll have to use the oil pump pick up from a 5 series too- the M50/S50 engines should have interchangeable pick ups.

The e36 M3 engine is MUCH heavier than the M20 original 325i unit. If you want to avoid the weight distribution of a Front wheel drive car and don't mind not having a heater- then remove the heater matrix and try to move the engine further back. The only problem with this is that the sump reccommendations I just made will no longer apply- I don't know what you'll have to do then!

If you keep the bulhead as is-You'll probably have to remove/junk the e30s standard viscous fan in favour of an electric affair probably mounted ahead of the radiator because the E36/S50 lumps cam chains/Vanos units will intrude into the area of the original Viscous/Radiator cowl.

Good luck- it's an involved task!

Cheers Rupe. I knew about the 5 series sump pan, but that's interesting reading. Thanks to Iggy for brake advice, too.

The chimps were pretty sorted for Tivs. Good choice

The Ultima is still at spaceframe stage, currently at an engineering shop for various chassis mods, engine and box prefit, seat positioning, 6 point belt mounting points etc.

Engine will be SBC 7.0 C5R Katech dry sumped special; good for genuine UK 600bhp I should think.

Completion date still years away as I can't afford all the bits yet

The E30 trackslag will be my cheap track toy.

ATB and hopefully see you for a beer in 2005

20kg i believe. its not so heavy, i managed to lift it into the back of a van on my own. best warm up before attempting this manouver though !!!

besides, fibreglass bonnet and 3deg neg front camber should sort any understeery probs. my biggest concern is putting 350bhp through such a light rear end - not sure understeer is going to be the biggest issue!

Francis- 350bhp? Evo or 3.0 lump? lots of work to get that from the latter & pretty highly strung id think.

3.0. dunno how - ask andy he's doing it. - nice thing with 3.0 is you can rev the nuts off it compared to longer throw 3.2.

Free flowing exhaust, no cats and stuff, the 3.0 must be good for an easy 300bhp. Not sure where the other 50bhp comes from, but it sounds like a good idea

herr fearns recons we can get that. god knows how. schrick cams ? hehe. if he has his way it'd end up with a rolls royce merlin, was trying to convince me to put a 4.2 v8 in last week.
