jonlewis Posted September 2, 2004 Posted September 2, 2004 Worth asking Julian Lane (Joospeed) if he knows any good ones for sale. Joolz is the most likeable TVR Mechanic around. Very, very honest and will tell you everything about them. He is based in Chesterfield and has a web site on www.joospeed.net Ignore the Cerbera theme as he knows all the ranges well. Quote
ChrisG Posted September 2, 2004 Posted September 2, 2004 ............. Anything above 4.0 ltrs is all down to stroke, because the block can't take any more. Maybe it was the cost of the crank etc then that made it expensive? Id assume you could use a stock Range Rover crank on the 4Ltr? Quote
Thrustyjust Posted September 2, 2004 Posted September 2, 2004 look in the back of TVR Sprint mag and give Rob Ingleby a call.He will find you a decent car.They are full of problems as am a previous owner of one.Went back to a westie.5 ltrs are re-known oil burners for some reason.A good high mileage car can be better than a low mileage,sat in a damp garage rotting chassis types.Watch out for crazing paintwork and NEVER GO TO A DEALER FOR PARTS.They wanted £140 a pair of front springs.Got them for £25 from elsewhere.Seem to think they have a licence to print money. Look out for grounding exhausts,drooping suspension,oil leaks,temp running probs,wing mirrors not working!!!!.Came from Citroen CX cars.Not any of them around now and you can pay rocket ship money for them.leakiing fuel tanks,outriggers rotting(get them looked at proffesionally,they know where to look and will be a body off job to resolve)damage round the windscreen material from fitment of new screens,as the screen is glued in and is very close to the fabric and gets slit when removed.Good Luck and hope that helps.Personally,if your not sure what to look at,call Rob.It could cost £500,but may save you £££££££ Quote
Martin Keene Posted September 3, 2004 Posted September 3, 2004 Maybe it was the cost of the crank etc then that made it expensive? Id assume you could use a stock Range Rover crank on the 4Ltr? I'll bet it ain't cheap... What scares me more is the rod angles involved with taking a 4.0 up to 5.3 just by stroking it... If it were my money 4.6 would be the most I'd go to, anything above that I find a bit... Quote
Mike H Posted September 3, 2004 Posted September 3, 2004 Many high perf 5ltr (and above!! engines use a 96mm bore which involves new liners that also have 'top hots' to prevent them slipping. There are all sorts of cranks available for either the small or big journal block some of which involve extensive 'mods' to the bottom end to give clearance but they seem to work! It may be worth contacting a couple of the decent Rover V8 tuning companies, they all do a lot of work on TVRs, and see what they say about reliability of the Griff 500 compared to other models.

chrisbin Posted September 3, 2004 Author Posted September 3, 2004 Thanks guys, some useful suggestions. Thrusty - agree with all you say. Those items are definintely on my list Sam - thanks for that vote of confidence!! Quote
Martin Keene Posted September 3, 2004 Posted September 3, 2004 Many high perf 5ltr (and above!! engines use a 96mm bore which involves new liners that also have 'top hots' to prevent them slipping. Thats one thin liner... the bores in the block are only 97.561 / 97.638mm diameter. PS: Yes, I did just dig out the project folder with the block machining drawings in... PPS: Yes, I am aware this is sad... Quote
Mike H Posted September 3, 2004 Posted September 3, 2004 Yep, not sure how they do it. Maybe they only use the thicker walled blocks you mentioned and open the bores a little so they can still have a decent thickness for the liner. Some options from V8D are here: http://www.v8developments.co.uk/parts.asp Mike Quote
chrisbin Posted September 3, 2004 Author Posted September 3, 2004 just a little thread drift lads.....!! And no problem as far as I'm concerned, particularly as it was all O/T anyway!!! Quote
Martin Keene Posted September 6, 2004 Posted September 6, 2004 Maybe they only use the thicker walled blocks you mentioned and open the bores a little so they can still have a decent thickness for the liner. Think we have got some wires crossed here Mike. As far as I know there isn't such a thing as a thick walled block. The current production casting when bored out to 97.561 / 97.638mm diameter, to accept a liner giving a 94.0mm cylinder bore, leaves a 2.0 - 2.5mm wall to the water jacket (pre liner). It's unlikey anybody has tooled up tp produce a thicker wall block becase the pattern cost involved to produce such low numbers would scare the s###e out of most people... Anybody actually know how they get 5.3 from a Rover... Quote
Mike H Posted September 6, 2004 Posted September 6, 2004 Indeed, the second operation on the line is to ultrasonically measure the wall thickness between the cylinder bore (pre-liner) and the water jacket. If it is more than 2.5mm it becomes a 4.6ltr. If it is 2.5 - 2.0mm it becomes a 4.0ltr and if it is below 2.0mm it becomes an ornament... that there was some variation in block castings and it would be possible to take the bore out further if done in conjunction with stronger liners ?? There is talk of a 6.0ltr Rover V8 too but I can't seem to find anything about it at the moment. Mike Quote
Mat Jackson Posted September 6, 2004 Posted September 6, 2004 Chris, Is the specialist you were talking about the one in Roath? Popped in there last week to see if he could recomend anywhere that would help set up my carbs. Very impressed with him. I always thought he was just a backstreet garage, but he obviously knew exactly what he was talking about and the garage was immaculate. Will be taking the Westy there to be set up when its on the road (few weeks I hope!! Mat Quote

A you say, impressive set up (within its limitations) and very nice guy. btw saw a black westy down at Porthcawl yesterday - Q plate, pinto or Duratec..? never seen him before! Nice car. You'll have to get that area meet going soon.... Quote

Mike H Posted September 7, 2004 Posted September 7, 2004 http://www.espritv8.net/id34.htm Found it, but is appears to be a 'special' block. Wonder if there were any more made? I'm sure I saw it mentioned elsewhere once too, but I'll have to dig through some old magas etc to see what I can find. Mike Quote
