Jake Posted December 14, 2005 Author Share Posted December 14, 2005 Glad you approve Charlie I know CW doesn't have much good to say about Wiseco pistons but apparently Ken Henderson from SP Engineering has used them in 800rwhp Supras and rates them with CP and JE pistons. They aren't as light as CPs but lighter than the stock ones. Quote Link to comment Share on other sites More sharing options...
Miguel Posted December 14, 2005 Share Posted December 14, 2005 Not bad pistons them. Slowly but surely all coming together ..top stuff...I would use smileys here but they seem not to be working again ...And its not my end as i havent touched a thing.

Jake Posted December 14, 2005 Author Share Posted December 14, 2005 What do you reckon about the bearings Mig? Should I replace the main bearings and big & little end bearings while I've got it apart? With stock ones or aftermarket ones? I was looking at the Power Enterprise PWR F-1 Black Bearings on MVP earlier but couldn't decide. What do you think? Quote Link to comment Share on other sites More sharing options...
Miguel Posted December 14, 2005 Share Posted December 14, 2005 Build to sell ..or build to keep for the power run ...answer depends on that. Alsp what is the age condition of the bearrings in there ? Quote Link to comment Share on other sites More sharing options...
Jake Posted December 14, 2005 Author Share Posted December 14, 2005 Build to last hopefully. Whether I keep the car or sell it I want it be right. The bearings in there look like new to me. They've done about 34,000 miles. Quote Link to comment Share on other sites More sharing options...
TLicense Posted December 14, 2005 Share Posted December 14, 2005 Actually i meant comparator' date=' as it takes a reading compared to an exact measurement (taken from a micrometer).Works in a similar way to a DTI to give a +/- measurement.[/quote'] OK. I know the exact thing you mean, still never heard it called a comparator This is the type I've got, but I've got the digimatic head. (Eyesight's not good enough otherwise!)

Miguel Posted December 14, 2005 Share Posted December 14, 2005 Well I was going to say OEM all the way anyway LOL..Toyota werent daft ;-). I'm still yet to be convinced that after market ones are any better than OEM. Theres an old saying .. If it aint broke dont fix it ..so if the bearings , crank surfaces all look like new and so do the bearings and they are all within spec wear wise and you kept them in order so you know where they go ;-) then i think that answers you question. If you want it all spangly dangly then go for broke bud ...nice run in period. If your on that much of a roll with all these flash pistons and bearings ...then bang some rods in ..you know you want to LOL Quote Link to comment Share on other sites More sharing options...

Ahhh bearings, there's another whole nightmare! Toyota sell 5 different sized bearing packs. numbered 1 - 5 unsurprisingly. The bearing type is stamped on the outer face of the bearing. You should replace it with a similar type. If you can't find the type on the bearing, then it can be worked out depending on which crank and cylinder block you have. (They made 7 cylinder blocks and 7 cranks - all of different sizes!) Edited:- beg your pardon it was 8 of each. They had a number 0 too.

Digsy Posted December 15, 2005 Share Posted December 15, 2005 What's the story on the standout on re-used bearings? I wouldn't have thought they would crush down as well the second time around. Quote Link to comment Share on other sites More sharing options...

No need to work it out Tony ..Toyota were kind and stamped the sizes if the bearings on the 1st blade of the crank for the rods and or the 1st bearing journal for the block ;-)..nice of em huh ....thats if no one else has been in there for a swap around.

Jake Posted December 15, 2005 Author Share Posted December 15, 2005 If your on that much of a roll with all these flash pistons and bearings ...then bang some rods in I'm tempted. Summit are doing Eagle Rods for $400 at the moment. The place I got the pistons from wanted $545 I'm not paying the silly money they want for Carrilo, Crower or Pauter rods though. The Eagles look like a good choice to me. Quote Link to comment Share on other sites More sharing options...

TLicense Posted December 15, 2005 Share Posted December 15, 2005 Also I've just found this out (I've got too much info in too many places!) Piston - cylinder bore oil clearance Standard clearance 0.073 - 0.096mm Maximum clearance 0.12mm So you're machine shop should measure the pistons and then machine the bore's to match, untill the oil clearance is the same. Howver, those values may well change given that you're using a different piston, and I presume different piston ring set. Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted December 15, 2005 Share Posted December 15, 2005 Listen to b'have, you need a Mercer. Digital calipers are nowhere near accurate enough. Bore to suit each piston, find out what clearance the piston makers recommend, and where they expecte them measured. Farm the whole job out if you have ANY worries!!!!

TLicense Posted December 15, 2005 Share Posted December 15, 2005 No need to work it out Tony ..Toyota were kind and stamped the sizes if the bearings on the 1st blade of the crank for the rods and or the 1st bearing journal for the block ;-)..nice of em huh ....thats if no one else has been in there for a swap around. Cool, I knew the block and crank numbers were stamped on the prospective parts but didn't know they then stamped the bearing size on it when assembled. Good idea Toyota!

Miguel Posted December 15, 2005 Share Posted December 15, 2005 My mains are all #3 or #4 , like you say it's stamped on the bearing. Wouldn't that change if I change the rods though? Technicaly no ..as the rods should be made to have the same ID as the stockers. But i have seen variations ..ALWAYS have a meassure up and check see. I have had rods that have been spot on where the wrist pin journal has been exact and the bearing journal also, seems to be the high end rods that are better made. Some have been a little tighter and some looser ..so this needed to be addresed. Quote Link to comment Share on other sites More sharing options...
TLicense Posted December 15, 2005 Share Posted December 15, 2005 My mains are all #3 or #4 , like you say it's stamped on the bearing. Wouldn't that change if I change the rods though? Odd that you've got two numbers? What's the numbers stamped on the crankshaft and cylinder block? If you add them together you can work out which bearings to use by adding the two numbers together:- 0-2 = bearing pack 1 3-5 = bearing pack 2 6-8 = bearing pack 3 9-11 = bearing pack 4 12-14 = bearing pack 5 We're talking about main bearings here mate. Changing the pistons shouldn't effect the main's. Or pehaps it's only me that's talking about main bearings. oops. Sorry to confuse! Quote Link to comment Share on other sites More sharing options...
Jake Posted December 15, 2005 Author Share Posted December 15, 2005 Sorry Tony - I was thinking of the con rod bearings. Quote Link to comment Share on other sites More sharing options...
TLicense Posted December 15, 2005 Share Posted December 15, 2005 Saying that, I suppose it would be a much better to measure each journal bore and diameter and then fit bearings specific to each one, rather than relying solely on Toyota having got all the journals within tolerance to start with.
