Replicate m30b35 in Alpina/Hartge

[E30335i]

If you look at the figures that Alpina/Hartge makes from that engine, it's pretty amazing at 261hp and 346nm Torque. I've contacted both companies and only way I can get replacement parts or more info is if I actually own one. But I do not so they cannot give any more info on it. I know I can turbo it instead but I read posts of people attempting to make na power and it's almost close but not enough. I just haven't seen anyone on the forum make a post about it so here I am doing it.

high compression pistons, aggressive cam, hours and hours of flow bench work will put you there.

Don't leave out Schnitzer and their 3.7L @ 275 hp.

And now we have better coating technology and engine control systems. Attention to detail will get you there.

I can't imagine it is worth it. Cost benefit is brutal. Cool factor of course. But lots of cash spent to be cool.

Lorin, I didn't for get about the AC Schnitzer 3.7. It is one of my favorite tuner motor.

Cost/benefit = chip and gear change

I spent under $1750 shipped on new custom pistons, and ported head/cam combo (which was an awesome deal). Another $ 450 on block magnaflux, boring, decking, cleaning and assembling my new pistons to the rods. Bearings, gaskets, timing chain, and miscellaneous engine hardware was probably another $400. My oil pump is not new but has good pressure.

Then there is the cost of a new clutch, hoses, exhaust... It all adds up but in my case I have a motor that should last for 200K plus with proper maintenance.

I just tried to order the Alpina headers last week. It's a two piece set. One piece is NLA and they wanted a VIN before they would sell the other. I'm a sad panda :(

Try ebay Germany. Some time they come up for sale between 300-550 euros.

FWIW the closer you want it to replicate an original Hartge, Schnitzer, or Alpina the more it will cost. Period correct is cool but expensive.

[navytapaul]

One would think they could be replicated with todays technology and aftermarket. Parts are still expensive though

Here, buy the whole car. It will be cheaper.
