so my gf has a 96 disco she cut up and made a buggy..

blah blah

well now we are converting to propane.

i'm thinking why we are in there might as well rebuild instead of put the new cover,intake ect. and then have to do head gaskets, and then end up needing a rebuild later

any opinions? or advice as far as rebuilding goes? best place to get parts?

are the liners big enough to have them bored out?

others wise wouldnt putting stock pistons back in a worn out liner = less compression?

 

Don't believe you can bore out these liners. They are slip fitted, not cast in place. Parts from all the usual sources including Atlantic British, British Pacific, Rovers North, BP Utah, and a great many more. And there are intakes from the carb era, popular with the lads from the UK that squeeze the Rover engine into MGs and Triumphs. Lots of engine mods available. "RPi Engineering - Specialised Rover Engines" and The Wedge Shop - Fast. British. Reliable

You will have lots of interest on this site for the propane conversion, so posts lots of pix. I have worked with a lot of V8 standby generators in the past, and the ones run on bottle gas certainly had cleaner oil.

 

Call Will Tillery and tell him you want his head gasket kit. He sells the bolts, gaskets, and a pair of machined heads with a valve job for around $600. Just have to send your old heads back. It's a good deal and a nice way to minimize down time.

 

thanks for the info! can you get thinner liners? to run a bigger piston ?

 

Or consider getting a whole engine from a wrecked one. You take a chance, but depends on GF's budget.

 

See http://www.google.com/url?sa=t&rct=j...Hko5O2FrvYc-Ow - those liners look pretty thin to start with.

 

dang they are way thin so there is no boring out to run bigger pistons? i need to do some homework.. im just thinking if shes going to rebuild it why not get a little more out of it.

 

The way to increase displacement on the RV8 is to increase stroke, by changing crank/pistons/rods as LR did when they moved from 4.0 to 4.6. Increase to 4.8 can be achieved by using 1964 - 67 Buick 300 crankshaft and '64 Buick 300 heads. Further increases to 5.2 can be achieved by custom crankshafts, connecting rods, and pistons. D&D fabrication is likely the best resource in the US for more info.

A standard rebuild isn't difficult. Just take it to a machine shop and tell them what you want done. Have them hot tank the block and heads, hone cylinders, re-ring pistons, valve job, check mating surfaces for flatness and resurface if necessary, replace seals, replace bearings.

 

Buy a real engine!! The lt230 is the only thing worth keeping and buck has created an adapter to the nv4500...

 

why not buy a 4.6 and make that nice instead?
