Starting to get somewhere now...



Then polishing up the exhaust side





Hard to capture the polished effect, and the camera picks up every spec of dust





And finished



I haven't done anything with the top of the combustion chamber, as I don't have the equipment to take very accurate fluid measurements, so just gave them a bit of a clean up

[The Batman]

you can port that more cant you?

[mandarinvx]

Thats the very first pass, from the valave head side, I've taken quite a bit off the dividing central piece, and flattened the walls out too I'll get a pic There's no need to open out the port size as it's already about the same size as the manifold (tho when I finally get an SC one I may have to fiddle with it again)

[mandarinvx]

This is the inlet side - I could have taken more off the divide, but called it a day before doing any irreversible damage



The crucial part on the inlet is the very restrictive area just beneath the valve, as the port sweeps nearly 90 degrees on itself back toward the manifold. This is where I had to buy the carbide burr for fear of burning the Dremel out



Prob remove about 1/4" on each port here


Thanks again to Vocky for the guidance

I ordered a couple of square yards of the carbon fibre fabric N1k found on the BMW forum, via JJJ

Really good quality material, and has a bit of stretch to it too



So had a play around with one of the easier, smaller dah plates today





I think it looks great

I think I'll try to do the door cards and steering shroud too, maybe even a centre console if I'm feeling brave!

looks sweet If you could get some seats retrimmed in that Your fuel cap and surround are cooking on the side as I type . I'll polish them up over the weekend and should be ready for monday

[mandarinvx]

Cool, cheers mate The material is actually pretty thin, part of the reason why it has a bit of stretch, it does make it easy to work with, but I wouldn't want to use it for any areas that need to be particularly hard wearing

A few pics of the GM set I ordered from Allecotec

Intake - new on the right; these are nitrated stainless, with an undercut stem



With single grooves for the keepers




And the exhaust - these are inconel, again with an undercut, new on the left this time






And the GM double valve spring kit



It looks like I will need to fit the valve guides too, as they are slightly smaller than stock

[theolodian]

Just curious, they didn't give you new retainers?

[mandarinvx]

Yep, but the bag is selotaped to the side of the bag with the valves in

[mandarinvx]

Had a go at some door cards today with the carbon fibre material, I like it and sprayed the door handle guards satin black too




Also got a stainless tow bracket from simsy, which I've now primed and painted black

[aron916]

loving the door cards! How hard was it to do?

[mandarinvx]

Harder than expected - this was the third attempt Came to the conclusion that 3M no. 90 spray glue and Bostik All Purpose Adhesive are the best combo to use

[Yellow_or_black?]

I'm not a fan of CF, but it looks like you did an amazing job there

[aron916]

I need to get hold of some of this CF fabric, i really want door cards like that!

Well done - looks good. Glad you tried it out first!! Going to give mine a go next week.

What caused it to be harder than expected?? How come 2 adhesives??

[mandarinvx]

The spray glue is hard to get to grips with, the cheap stuff doesn't give enough hold and is too watery; the intermediate stuff (Maplins version) gave good hold but was lumpy I used the Bostik to stick down the fabric edges behind the panels, and also used a bit where the spray glue doesn't give enough hold - around the window winders and the handle area on the door cards; only a small amount is needed. I found it best to let the spray glue sit for a few mins before applying the material - you only really get one shot with positioning tho!

I have just sat there and read all 12 pages. Absolutly brilliant job. Im only buying a black vx now. Not accepting any substitute!!

[mandarinvx]

Cheers mate

[Yellow_or_black?]

Oh yes, I meant to mention - the spray glue in LIDL is called Flash Bonder. It says it allows repositioning for something like 60 mins or something - can't remember the exact figure, but it seemed impressive. Mention of it here for one
