My 240Z with supercharged BMW engine

Recommended Posts

Thanks!  :)

I quess my calculations were off because this only boosts about 0.5bar. I calculated that with this pulley boost pressure would be about 1 bar. Because pressure is so moderate there is not so big difference compared to NA engine. Well I can always change smaller pulley... ;)

Went to dyno yesterday. There was 360hp/420nm and that was only with 0.4bar. I am quite happy with results as boost pressure was so low. So there is much improvement available with smaller charger pulley. Also that 2.5" exhaust is too small so I need to do it again.

I ended driving season this week. Drove little bit over 5000km in this summer and not a single problem. Attended few drag racing events and best time was [email protected] Those were at airfield so traction was not so good. 

 

For next summer there is not going to be much changes. Little bit more boost, better intercooler and larger exhaust. For outside I bought original mirror to replace that plastic one and Euro-style front spoiler.

I got this aluminium radiator to replace original. I also put Spal electric fan so original fan shroud would not fit. I modeled new shroud, machined mold and used carbon fiber to made new one. Still needs few layers of clear coat and it´s ready!

Finally found time to finish fan shroud so radiator is ready to be installed. I cured that part in sauna. It made quite a bit difference to part stiffness. After that is was clear coated.

I modified Nismo-style front spoiler. Now it fits quite well and atleast in my opinion it looks better. Now I need to make mold from it and manufacture new part.

Is is this one.

I ordered euro spoiler and because part is so big air freight to Finland would have been very expensive so I used ship freight instead. After waiting about 2-3 months it arrived but then I noticed they send me this Nismo-style spoiler instead. They would have send me new one but it would take another 2-3 months to arrive so I decided to keep this one and modify it. They gave me refund so can´t complain their customer service.

 

I like it much more now when those air intake holes are removed but it is little bit too big for my taste. Need to see when it is painted do I keep it or not.

Ive been dying to do a BMW engine plant into an early Z car. This inspires me even more. Ive been drooling over a N52 swap for some time after watching from of the european guys strip down those 1 series. Though my idea of fun is to put that into abase model slicktop manual everything S130. 

 

There was a car that kicked this all off many years back that disappeared. I feel like it was wrecked, the one that got the full 3 series suspension. Maybe BRAAP was involved, but I I have also been watching RTz as well. At least in the USA, BMW is one of the last manufactures offering a viable Inline 6 still in production, thinking of the future swaps available. So keep up the good work!

That N52 or N54 would be nice modern 6 cyl option. Haven´t looked if some of those engines have rear sump, if not it is not as simple swap as this was.

 

Im on the fence what to do next with engine. More displacement, turbo, more displacement+turbo, or totally different engine. European E36 M3 engine would be nice, too bad those are hard to find and quite expensive.

Bored with the rotrex already?

 

 

If it were my car, I'd be looking to move toward an aluminum block. Either an Al M52 block, or toss the M52 for an M54 , which should be much easier to find. It's been swapped into an E30, so there should be an easy rear sump oil pan solution if it isn't rear sump already.

No not yet bored, especially as there is still much more boost to be founded. But always need to think next step.

M54B30 could indeed be good option. Those are cheap, have dual vanos, and as said have aluminium block. And I remember correctly this sump that I currently have fits to that engine.  

 

That engine combined with Rotrex could be nice combo. But next summer is going to be this old engine.
