Fitting solid lifters

Just a quick question.
Is it possible to fit the lifters and correctly size the shims at home, or best left to the engine building people? If it is doable at home, precisely what is involved? I have previous experience of faffing with engine, but only older push rod stuff. OHCs are still a bit modern to me!
Also, will any cams do, or do I need the ones the engine will run with? I intend to uprate to the GTA cams, but won't have them for a while yet. I do still have the stock 2.5 cams though.

Re: Fitting solid lifters

the gta cams will fit straight in, you will need the gta cam locks to time the engine correctly, the lifters are hydrolic so just pull out/drop in

Re: Fitting solid lifters

Whilst the current lifters may be hydraulic, the new ones won't be. I'll be building my engine to turn a few more revs than standard. I may go with the GTA cams, but I may well go for something a bit spicier.

If you are looking for high revs, then you need the appropriate camshafts, which will not be the std GTA set.

Re: Fitting solid lifters

I had a feeling that would be the case, but I've not finished doing my homework just yet, so I'm unsure quite what would be the best way forward. I have a few more phone calls to make yet.

Re: Fitting solid lifters

Take a look at Colombo & Bariani, they have four set of cams for the 24v V6. The three different road cams all run with the hydraulic tappets. The race set use solid, but will you need your engine to pass road emissions? That can be difficult with race cams.

Re: Fitting solid lifters

The engine will need to pass it's normal emission test at least once for the SVA/IVA, and possibly every MOT there after. I hadn't looked very much at C&B as yet, they're on the list of people to enquire about. Whilst I appreciate the answer to this will depend upon engine spec, what cams would you choose if you wanted to build an engine to have peak power up around 7-7.5K rpm? And still pass an emissions test. Or is that being overly optimistic on my part?
Outright power is important, but so is having some low down drivability. For some reason, I just love being able to rev the balls off my engines!

Re: Fitting solid lifters

Just had a quick look. £1500!!!??? That's a bit more than I was hoping to spend to be honest. Any one know if it's possible to get the stock cams re-ground to the spicier profiles?

That is about how much four new cams will cost, there is no getting round the fact that you have four of them!

You can try AH Motorsports to see what they can do.
They also have a solid lifter set at £575+VAT

Re: Fitting solid lifters

I knew it wouldn't be cheap, but I come from the world of tuning minis, where you can get a billet cam for less than £200!
Oh well, since I can keep the normal lifters (I didn't expect to be ale to you see), I'll see how much the re-grinds are first I think.

Even @ £200 each, four would take you to £800. OK that is still less, but you get my point. There are a lot of bits in the 24v V6 when you start to modify it.
It doesn't take long to get to or past £10,000

Re: Fitting solid lifters

Ah ok, I've read/been told that the hydraulic lifters would start to struggle much past 7,500. So to get the cams re-profiled I need to get a set of GTA cams? I take it there isn't enough meat on the stock 156 cams to allow the re-grind?
