Hi,

Its been a while since I've posted anything, I will post some more details of what I have done to the engine but I would just like to share the final dyno numbers.... 406hp@6500rpm and 396lb/ft@4000rpm....

I have used Victor Reinz gaskets and there are steel so don't crush and have measured them in several places with an average of 2.4mm (all around the combustion ring area...

The head bolts are of a stretch style so need replacing...

Iain,

You can skim the pistons by 1.0mm as they protrude from the block 0.5mm and use the head gasket from a late M62 fitted to the range rover, there steel and are 2.4mm thick...

Hi Iain,

I have gone the stroker route, the capacity I have ended up with is 4733cc,
I used the crank and rods from the S62 M5 engine, I have also used M5 cams, valves, valve springs, retainers etc, I have also raised the compression to 11:1....

I have also found some interesting stuff about the ...

Hi to all,

Been a while since I've post anything as I have been a busy body building two track cars for friends of mine, so the progress on the beemer has been slow...
However I got stuck in to it about 6 weeks ago and she's getting there, few issues with the engine build/modifications but soon she ...

Hello bud,

Looking good, nice to see the work continuing, will be nice to hear it running..

I have also got a b6 s4, mines a avant, still got my BMW, now going to biuld a 5.0ltr for it....

Steve.

Hi Iain,

I linked the big vacuum pipe work up and blocked off the smaller ones..

I haven't done anything to mine at all lately, just working out/researching what parts I'm going to need biuld the 5.0ltr M62, I've decided to ditch the ITB's and return to the original M62 inlet manifold, but hoping ...

Hi,

I out sourced the mount flanges, but made the mounts myself, the oil pump is an X5 pump that's lengthened by 98mm to move it back to the next main bearing, you need new shaft etc to be made and spacer parts then someone to weld it together.... They also made the flange for the sump, I then did ...

Hi,

My car still has the original in tank pump it the mo, but I'm going to change it for one of the walbro 400 pumps you can now get, the stock pump is supporting 5bar fuel pressure and nearly 360hp...

Oil pump choice is entirely up to you, can't advise you either way, just wrote this thread to ...

Hi Iain,

They look nice, similar to mine, there a bit thicker than mine, what sort of money are they...???

I'm going to sell my ITB's once stripped off the car (not the adapters)....

Iain are you using the M5 velocity stacks or shorter ones...???

Hope to post up some pics of the supercharger ...

Hi Iain,

I think the ITB's work ok, but depending on the application, if I were to lower the gearing strip out the interior and track it they would work well, but I just want it to be an easy car to cruise in and also to be mental road car as well, the ITB's have spoilt the low down grunt ...

Hi all,

Sorry for not posting any info lately I've been very busy at my new job...

Right after some serious messing about with cam timing, inlet trumpet length and 3 sessions on the dyno (over 15 hrs in total) I have some interesting results....

First dyno session she only managed 291hp@6900rpm ...

Hi,

Not sure I have pics but I will check to make sure, the trumpets are made from 3 different pieces in the end, the bell from eBay, the bottom part made by my mate and some silicone, in the video the it only shows top and bottom parts taped together to run her up, you could just buy some ...

Hi Iain,

This is indeed my car, there are M5 throttle bodies with unique trumpets, they are direct to head on the M5 engine, but the heads are very different, in fact the only thing they have in common is the port spacing, so I made adapter plates from 10mm thick alloy bar and some trick bolts ...
