Ok Guys,

I am trying to estimate how much it will cost to get the manifolds changed.

I have already purchased them from David Geralds, so am purely looking for labour

What are your experiences ?

the starting rate I have been quoted so far is £120, IF everything goes to plan !!

It should only take about an hour or so if everything comes undone without a problem but at such high temperatures the threads always seem to corrode together. £120 doesn't sound too bad.

I took a set of mainfolds off my spare set of heads the other day, all was ok bar one stud which snapped. Like Kentish said around an Hour to 2 hours work if all goes to plan and no studs snap. If somthing does happen then it's anybody's guess.

No, that was Austec... and none of the bolts snapped either. £120 sounds cheap... I'd go for it.

I thought it might be but the opportunity to pull your leg couldn't be missed.

Mine will probably need doing at some time in the next couple of years (sooner if my leaky exhaust turns out to be manifold and not downpipe ). Thing is, I don't need to use my car every day and I thought that paying someone for 4 hours labour to remove manifolds with snapped studs etc would be quite expensive. If I have the time, I plan on doing the following:

I am going to find myself a pair of good heads from a scrappie, and have them polished, ported, angled valve seats; using the money that Austec or other would have charged me for getting my snapped manifold bolts out.

Then, when it's manifold replacement time, I shall simply remove the current heads with manifolds in place, put them to one side for leisurely removal of buggered studs, and fit the flowed heads and stainless manifolds.

Anyone else done something similar? Or am I about to find out that the TVR does not have the standard Cologne heads...? Or that flowing the heads will necessitate £9million of rolling road/chip/setup/general nightmares...?

I was planning on doing somthing similar, until before the car went off the road. I had a whole spare engine, but I had to split it when I moved back South. I've currently got the whole top end for it. I was going to do the ported flowed route, but I have other plans in the works which may put a spanner in this.

A couple of the guys here have ported and flowed heads, some with a fast road cam, Somthing along the lines off a Kent 276 IIRC.

If you alter the engine in any way, you will be better off with a reprogrammable chip and a rolling road session. A standard car will benefit form this anyway as the V6 Ss were not set up correctly and use a variety of different ECU programmes, or so I am told. But flowed heads will definitely necessitate a trip to Austec or similar.
