kylestt Posted January 31, 2008 Share Posted January 31, 2008 All are good brand. I recommend CP for any build but again, all are good brands! Most commonly used here in the USA on the high hp, most reliable builds are the CP Pistons. Link to comment Share on other sites More sharing options...
Syed Shah Posted January 31, 2008 Share Posted January 31, 2008 1. JUN (Cosworth) 2. Arias 3. CP All on your budget. What rods you going for? They are first in line for an upgrade as opposed to the piston. Link to comment Share on other sites More sharing options...
supradibbs Posted January 31, 2008 Share Posted January 31, 2008 CP with corrilo rods Link to comment Share on other sites More sharing options...
TLicense Posted January 31, 2008 Share Posted January 31, 2008 I'm considering this very question myself at the moment. The common options seem to be either Jun (approx £1100) CP (approx £500) Stock I'd love to go for the Jun's but am currently weighing up whether the money spent on them could possibly be better spent elsewhere, or if they are worth the investment. As has been mentioned, it's also worth getting decent rods, so it's a question of working out what your budget is and then going for the best comprimise that you can afford.

tooquicktostop Posted January 31, 2008 Share Posted January 31, 2008 Mark at Phoenix swears by stock pistons with uprated rods and rod bolts for all his rebuilds (with a new bottom end), only with very large BHP builds need the expence of uprated pistons ?

Wez Posted January 31, 2008 Share Posted January 31, 2008 I would go for the lightest I could budget for. Link to comment Share on other sites More sharing options...
Gazboy Posted January 31, 2008 Share Posted January 31, 2008 Don't the JUN ones have some funky oil thingybob on the underside? Link to comment Share on other sites More sharing options...
Nic Posted January 31, 2008 Share Posted January 31, 2008 Jun (approx £1100) I can do them for a bit less than that. I'd go with JUN pistons and Carrillo/HKS H-Beam rods Link to comment Share on other sites More sharing options...
Muffleman Posted January 31, 2008 Share Posted January 31, 2008 Don't the JUN ones have some funky oil thingybob on the underside? Different to the stock oil squirters ? If you're not running silly boost\hp levels and don't need to shave a few grams of rotational mass, stock is fine. Link to comment Share on other sites More sharing options...

I thought they were the only aftermarket pistons that had oil squirters like the stockers???? Link to comment Share on other sites More sharing options...
Gaz Walker Posted January 31, 2008 Share Posted January 31, 2008 1. Jun/Cosworth 2. CP (we use these, although in terms of VFM, they should be No. 1) I'd imagine the Tomei ones are very good too. Gaz. Link to comment Share on other sites More sharing options...
Lee P Posted January 31, 2008 Share Posted January 31, 2008 I use CP Pistons & Corrilo rods, the CP piston are not too expensive either. Link to comment Share on other sites More sharing options...
Wez Posted January 31, 2008 Share Posted January 31, 2008 I have listed some engine part weights here, if anyone has more info let me know so I can update the doc. Weights Link to comment Share on other sites More sharing options...
SimonB Posted January 31, 2008 Share Posted January 31, 2008 I thought they were the only aftermarket pistons that had oil squirters like the stockers???? The oil squirters aren't part of the piston, they are attached to the block and squirt oil up and under the crown of the piston. What the stock pistons have though is channels that channel the oil to cool the piston better. Jun pistons and Carillo rods is what I've gone for on my old engine I'm rebuilding.

Sean1933 Posted January 31, 2008 Share Posted January 31, 2008 Jun pistons and Carillo rods if i could afford it...otherwise CP pistons and Carillo rods...or if its a budget/mid power build then Wiseco/stock pistons and Eagle rods. All with ARP rod bolts. Link to comment Share on other sites More sharing options...
Chris Wilson Posted January 31, 2008 Share Posted January 31, 2008 Tomei do a forged piston with an oil cooled under head gallery for RB26 engines, like the stock cast RB26 piston. Not sure if they offer anything similar for the MKIV. The oil cooled gallery pistons for the RB26 are VERY expensive though. Link to comment Share on other sites More sharing options...

Tomei do pistons for the 2JZ with oil cooling also, some spiel here http://www.tomei-p.co.jp/_2003web-catalogue/efr-set_piston_rset.html Link to comment Share on other sites More sharing options...
TLicense Posted February 1, 2008 Share Posted February 1, 2008 So approximately how much are we looking at for the Tomei ones then Nic? Link to comment Share on other sites More sharing options...

Nic Posted February 1, 2008 Share Posted February 1, 2008 So approximately how much are we looking at for the Tomei ones then Nic? The Tomei ones I'd guess would be around 25% cheaper than the JUN ones, although I'll need to check actual price if interested. Link to comment Share on other sites More sharing options...
Chris Wilson Posted February 1, 2008 Share Posted February 1, 2008 Can't see 2JZ ones with cooling channels Nic, see http://www.tomei-p.co.jp/_2003web-catalogue/efr-set_piston_rset.html Look under the 2JZ menu, no cooling channel pistons. Then look under RB26, where they show the ones I have in my RB26 engine, listed separately to the normal solid crown ones. Link to comment Share on other sites More sharing options...
DaveSupTT Posted September 15, 2008 Share Posted September 15, 2008 Just bringing this thread back to life, although its not been asleep for that long Just trying to decide myself what is best. The ones I am conserding are Wiseco and CP, aparently there is not much in it budget wise. After speaking to various technical people, some prefer CP where as others dont like them at all. What are the main pros and cons for each. Im rebuilding my engine and it will be running 1.2 bar, its BPU and has Hybrid turbos. I will not be increasing pwer any more ie going single. Thoughts please. Link to comment Share on other sites More sharing options...
