Big Supes Posted October 9, 2013 Share Posted October 9, 2013 (edited) Hi, I was just wondering how much a engine recon kit would cost for someone wanting to strip an engine to be reconditioned. I guess it would be: Cylinder head assembly (gaskets and oil seals) Bottom end assembly (shells, big ends, rings, gaskets and oil seals). The only uprated part would be the head gasket for the option to run more boost later down the line. Cheers.

Tyson Posted October 9, 2013 Share Posted October 9, 2013 Hi, I was just wondering how much a complete engine overhaul kits would cost for someone wanting to strip an engine to be reconditioned. The only uprated part would be the head gasket for the option to run more boost later down the line. Cheers. There are many levels of rebuild depending on what actually needs replacing. A total kit would include basically everything apart from the block itself e.g valves, rods, pistons etc are you just talking about seals and gaskets ?

Big Supes Posted October 9, 2013 Author Share Posted October 9, 2013 Hi mate, I've edited my post to be more specific. It would be to service the internals on a high mileage motor. No need for valves, rods, pistons or the block itself. Quote Link to comment Share on other sites More sharing options...
jay200bhp Posted October 9, 2013 Share Posted October 9, 2013 everything in it would be cheaper to buy a short motor from toyota ... at around £2300 ..my motor with forged bits and all inclusove costing has just tipped eight grand..you have about 2000 in labour plus machining block.head skim.valves re grinding and pressure leak down test.. new oil pump water pump full gasket set .crank pulley ? the list goes on and on !

Big Supes Posted October 9, 2013 Author Share Posted October 9, 2013 I wouldn't be interested in going the forged route and would plan to do the rebuild myself... (and with the help of any local club members ). Would the block would need machining? Would definitely skim the head, but I have a friend who could do that.

Guest Roger NE Posted October 9, 2013 Share Posted October 9, 2013 If it's a high mileage engine, surely you would want to have the block re-bored and oversized pistons fitted ? Equally you should have the crank ground and oversized new big end bearing shells . . . . plus new small end bearings, oil pump, water pump, oil seals, etc etc Then there's the head of course - at the very least, skimming, regrinding all the valves and new valve stem seals Then putting it all back together with new gaskets That's what re-conditioning an engine is . . . . what were you thinking of NOT doing?!

Swampy442 Posted October 9, 2013 Share Posted October 9, 2013 What do you class as high mileage? These engines do 250k miles without rebuilds. Plus a stock head gasket can take lots of powerz. Quote Link to comment Share on other sites More sharing options...
Big Supes Posted October 9, 2013 Author Share Posted October 9, 2013 (edited) If it's a high mileage engine, surely you would want to have the block re-bored and oversized pistons fitted ? I'm no expert, but I have rebuilt a few engines... maybe I'm missing something, but why? Equally you should have the crank ground and oversized new big end bearing shells Depends on the crank, but I would cross that bridge on assessment. At the moment I'm just after a rough price of engine rebuild kits. . . . . plus new small end bearings, oil pump, water pump, oil seals, etc etc Of course, plus timing belt, tensioner/crank pulley and the other obvious parts. Then there's the head of course - at the very least, skimming, regrinding all the valves and new valve stem seals As previously stated, I have a friend who would do the skimming. I wouldn't regrind valve seats unless there was a compression issue. Then putting it all back together with new gaskets Which serves the point of this thread. That's what re-conditioning an engine is . . . . Maybe according to a particular set of guidelines set by a specific company, but I'm no company and it would be for my own use. Re-boring with over sized pistons and regrinding valve seats ISN'T all that important for me at this stage. Of course, upon assessment of the internals, that could change, but for the time being, they're not factors. what were you thinking of NOT doing?! A couple of the jobs you've mentioned.

Guest Roger NE Posted October 10, 2013 Share Posted October 10, 2013 Well it sounds as if you want to make sure it's going to be OK for another 200k miles . . . but don't want to replace the parts that wear ! Personally, if you're not going to do a full re-con (as I've described), I wouldn't have thought it worth taking it apart at all if it's running OK!

I think he has agree with you tbh, just disagreed on the over sized pistons part and the crank would be assessed when it's removed, tbh unless there is damage to the bore the wouldn't need any work, but this depends on how well looked after the engine has been, over sized pistons are a cost that you don't really need if you can avoid it in my opinion.

Rob_Mitchell Posted October 10, 2013 Share Posted October 10, 2013 be better off buying my forged engine, put new piston rings and oil pump and you got yourself a quality built engine for less than it would cost to have rebuilt in just parts Quote Link to comment Share on other sites More sharing options...

Personally, if you're not going to do a full re-con (as I've described), I wouldn't have thought it worth taking it apart at all if it's running OK! Piston rings are designed to wear. The bores, unless there has been some serious over or under fuelling, or oil starvation, generally don't need machining. Just run the honer down there and you are good as gold. Re-boring cylinders and fitting oversized pistons is a sure way to piss away a lot of money. The same applies to the valve seats. It's subjective, but some people who merely want to assess an engine and replace the wore parts wouldn't even touch the seats unless there was an issue. I could send them away (perfectly fine) and have them come back in a worse state. It's just more needless expense, but don't mind me. Crack on, mate. I'm going to leave it here. I only wanted to find out if someone here does an overhaul kit and how much the price was, instead of debating what qualifies as an "engine recon". I think he has agree with you tbh, just disagreed on the over sized pistons part and the crank would be assessed when it's removed, tbh unless there is damage to the bore the wouldn't need any work, but this depends on how well looked after the engine has been, over sized pistons are a cost that you don't really need if you can avoid it in my opinion. Honestly don't even know how we got into discussing what parts need to be changed. All I know is that I would be fuming if someone charged me for machined bores and new pistons if the current ones were fine... on top of disturbing perfectly fine valve seats at my own expense. Apart from the obvious, one of the biggest reasons for stripping this engine would be to see how it has been running, as well. A lot can change in an engine build upon assessment. It would be nice at least to see what's been going on a replace what needs to be done. be better off buying my forged engine, put new piston rings and oil pump and you got yourself a quality built engine for less than it would cost to have rebuilt in just parts Being honest, I still don't know how much reconditioning an engine will cost. If forged is cheaper (which makes zero sense), I will more than happily go that route, although it would be nice to spend that additional money on the tuning instead as I'm never going to need uprated internals for the power I'll be running. Time to get online and build up a quote for the parts needed, me thinks. Quote Link to comment Share on other sites More sharing options...
Rob_Mitchell Posted October 10, 2013 Share Posted October 10, 2013 All im saying is you can buy my forged engine for the price it would cost you in "stock new parts" lol. No head work is needed as its all brand new, so the cost of a gasket kit is not needed ect, which i believe are £250ish from toyota for a full kit. Its always a tough call but i know what i would do if i was in your position. Quote Link to comment Share on other sites More sharing options...
Big Supes Posted October 10, 2013 Author Share Posted October 10, 2013 That is good news, mate. How much does a forged motor cost? Any ideas on suppliers? Cheers. Quote Link to comment Share on other sites More sharing options...
Rob_Mitchell Posted October 10, 2013 Share Posted October 10, 2013 stupid money mate £3k+ ect. The one i have forsale has JE Pistons and all ARP bolts ect, we think it might need new rings but thats no drama and hence the quick sale price.

Big Supes Posted October 10, 2013 Author Share Posted October 10, 2013 Ahh right. In that case I think I would go for the £2500 short motor from Toyota option and put my head on it. Forged would be nice, but it would definitely be wasted on me. Quote Link to comment Share on other sites More sharing options...

You could just buy mine for £1200, new rings and you got yourself a perfect £3k motor if you ever decide to sell ect you would have doubled your money, plus its not wasted on performance? who knows what your do in the future.

Being honest, it wouldn't be this side of Christmas if I did. I'm currently mustering the funds for the car I've seen so, if all goes well, get it, get Xmas out the way and then plough into it in the new year. plus its not wasted on performance? who knows what your do in the future. I have told myself I will not let another Supra own my wallet, but you could be right. Quote Link to comment Share on other sites More sharing options...

Trying to be head strong, but I know the cracks will start appearing if I see other members cars and the power they're packing. Quote Link to comment Share on other sites More sharing options...
