what is an 'early' 3.4 996?

Thanks Slippydiff,

Just took a look at his website, I need to sort a very slight coolant leak and radiator resistor first then I'll look to book it in.

Interestingly I note that he suggests an extra hour for mapping a C4, I've converted mine to RWD so I wonder if that would make a difference.

I'll send him a message when I'm ready to make a booking.

I'll be very interested to see how it goes. I've just given in the temptation and fitted some eBay headers. They sound cool but I'd have thought tweaking the map might get some additional power too.

There is an interesting clip on YouTube of a guy who stage by stage removes the backboxes then removes the cats then dynos the car at each point to see if there is an exhaust restriction. That's on a 997. He does make power at every stage and points out the car runs rich (or lean, can't remember!) at the top end suggesting there is more power to be found. That's on top of driveability improvements as previously discussed.

Anyone know of someone in London/south coast who is a decent mapper?

I know it's a long way to go see Wayne but I'd go there if I were you. He really is that good. Can you post a link to the headers you bought please?

I've just been watching the FGP video about the big repair they did for a customer's yellow C4S. They even had 2 more in the background at one point in the video. So 3 speed yellow C4S all together. The number of cars there now is really surprising. He must be doing a lot more maintenance type work. I'm pleased he is doing so well and raising the 996 profile.

I watched that also. I'm not really a fan of yellow but that particular car looked great and looked to be in fine fettle once they'd finished with it. I've enjoyed quite a few of their videos.

Cheap enough if they're crap I'll bin them. Seem to be excellent quality though, welds look good and have been ground back internally, bolted up very easily.

Not that the header bolts will most likely all snap, that's the real issue with fitting these but I've drilled mine out in preparation for some other work I'm planning.

Thank you.

I'm preparing myself for having this job done over the coming winter. As an aside, as someone who's usually modifying BMW, it's great to be able to buy headers and not worry about them potentially fouling the steering column etc.

If you discount the 6+ hours it took me to drill out the header bolts (erm....)

fitting the parts took me all of 30 mins!

Is it worth spending a week soaking the old manifold bolts in WD40?

[barryrs]

This is a job I think I may need to address in the not too distant future and wondered if a handheld bolt induction heater might be a worthwhile investment?

There’s a few options around the £200 mark.

[Chris Stott]

19 hours labour to fit a complete exhaust on my 996... fortunately I'd agreed a cap.

Maybe we should buy one as a collective?

Nope. They really need to be drilled out. I've never seen anyone have any luck with lubricants, the corrosion is around the head/manifold interface and forms a seal. And you've got gravity working against you. I don't think an induction heater would make much difference either, the bolts get so weak where they corrode.

I have one and they really are very impressive. Mine will get a bolt glowing (as in, bright red in the daytime) hot in about 30s. I have yet to try it on the manifold bolts (i'm not doing that job until it needs doing) but it might help.

If you already have one it has to be worth a go. I'm thinking I'll drop the engine over the winter and do them then. (when I say that I mean get them done as I have the mechanical skill of cat food)

This ^ As all too often the threaded portion of the bolt has turned to chocolate with the constant heat cycling, and as soon as you heat the head up and apply torque to it, it snaps the head off. That of course presupposes there's sufficient of the head and its hex shape left to actually apply torque to after the years of oxidation ...

A set of these might come in handy to shear the bolts heads off with

Possibly but not sure. They said the underside was a mess and it also needed a repaint. Then they fitted standard m030 suspension. There are better options available now. But yes after a repaint and new suspension and brakes and caliper refurb and whatever else its a nice car but it must have been a bit of a mess before that right. That's the problem with these cars. If you use them then they age. And then they cost money. I think he spent 10k on that car. That's serious money.

[Fast Bug]

My manifolds will need doing at some point. Neither my indi nor me are looking forward to it

[HughG]

Mine’s booked in for manifold bolts too, my track record with drilling out sheared studs isn’t good so I decided not to attempt it myself.

[jonny996]

The only up side of having your engine shipped to Hartech is they remove these before shipping

They have a pretty detailed page here with menu pricing for a lot of jobs. Only just noticed this and it's an interesting read.

Their pricing seems pretty reasonable to me. Smaller stuff I would most likely do myself but at that price I would most certainly get them to do the clutch and rear main seal.
