Are there no women in Finland? Do you guys not work?! Or are you just stuck in the shop half the year?
Seriously I've seen some great builds come out of the Nordic regions and this is yet another.
Great work, a real inspiration.

 

No doubt.  I'm still trying to get Megasquirt going, for two years now.  Kids, wife, work, home, never ends.

 

Sorry, yes, nice build, love it.  :D

Otherwise all stock.

Well its long and dark winter in here, so theres much time to spend in garage. :)

 

Got car back to the road again. I dropped engine and transmission off, because it seemed almost impossible to remove transmission with engine in place, because it is placed so close to fire wall. Changed new gasket to transmission and put everything back together. And after small test drive there was no oil leak. So hopefully I can now book new dyno time and get this thing tuned.

I took car to dyno today. 273hp, 334nm. That high compression + E85 really helps!

273HP? That can't be right. I would think a stock M50 might make 173hp at the wheels, but nowhere near 273. The car is looking fantastic though - I didn't recognize it at first, but I think I remember seeing that one on CL around summer 2013 - you've done a great job with it. Kinda wish I'd bought it in hindsight, lol.

A car is a hole in the air, suspended there by four rubber doughnuts which you can not eat.
Into this hole, you throw money, which you will never see again.

That is converted engine power and this is not stock engine. Compression is 12.8:1 instead 10:1, cams, ported head, manifold, and MS3. And because I use E85 there could be used high spark advance without knocking.

Gotcha - didn't see any mention of mods so I assumed it was stock.

Found original front valance and replaced that MSA front spoiler. Like this look much better.

Engine bay is quite a mess, so need to weld all those extra holes and get it painted again. Also need to hide those electric wires.

Driving season is soon to be over so needed to figure some new project for winter. So I designed ITB´s for my car. Going to use ready made manifold, RB26 throttles, and rest of the parts needs to be manufactured. Also those RB26 ITB:s are too wide so they need to be modified. 

 

What air filters have you used with ITB´s? In that design I used largest oval K&N filter element.

That is a real nice rear differential forward-mount. You wouldn't happen to have any schematics or drawings for it that you would be willing to share? I'm working on an R200 short nose swap myself.

TeemuM would you be willing to share who made your CV shaft adapters or a CAD drawing by chance? You're car looks really nice by the way!

Im afraid I have only 3D model of that mount. I can email that if it helps? I remembered that some of those parts needed to be modified and I added extra support but those parts were good starting point.

 

_full.jpg

 

And I also needed to bend that right side sheet.

 

_full.jpg

 

 

And for that new companion flange I dont have drawing. They did it by themselves is machine shop. 

 

My first idea was to make it by using original companion flange and weld adapter to that. As that seems to be what most people are doing. But they said in machine shop that they can do me a whole new flange so I think that was better.

 

Here is drawing of that welded adapter that I first was going to use.

 

_full.jpg

 

Idea was to make original flange round with lathe so it can easily be centered to that adapter before welding. That white part is original flange after lathe work.

Hope those helps.

273 on a modern N/A L6? That's awesome!

Well I think that dyno is quite optimistic because that torque is maybe too much from 2.8 litre engine. That´s almost 120nm/l, which is at Ferrari territory.

However 1/4 mile final speed was 175kmh which is quite in line with hp and weight.

 

I have already gathered parts for 3 litre 13:1CR engine so going to build that in next winter. Going to use aluminium block which is about 20kg lighter than that iron block.

The drawing you posted is great, thank you.  If you are willing to share your solid model of the diff that would be very helpful as well, my e-mail is jeremyw63d@gmail.com and I have solidworks 2014. Thanks again for the part data and sharing your build!

I send you .stp file and also found .dxf files that were used to cut those sheetmetals.

Be aware that this mount puts differential quite high. I needed modify floor panels to make enough room for it.

 

_full.jpg_full.jpg

 

Also that beam that is behind diff needed to be modified.

Thank you for the files and the details on mounting height. These should give me a great starting point when I get to the rear suspension and drive train of my build.

Velocity stacks are done. Took quite a few practice runs, but finally managed to get 6 somehow good.

My new engine is now assembled. It is stroked to 3.0 litres and compression is 10:1. Head is rebuild and slightly ported.

I changed plans and decided to supercharge it because I found used Rotrex C38-71. That means I need to upgrade also clutch, fuel pump and injectors.
