OK so I ran a search and looked here and there, many running a few piston types and brands. Looked through the thread in the quick ref as well. Something that seemed to be missing from many of the threads were a few possible choices and perhaps some info. I am wondering why I don't see many if any Jap brand names being thrown around, is it purely price? So far I have learned Venolia are at least 'buyer beware' and most others are quite good as long as the clearances and ring choice are right. That and the engine builder doesn't do something dumb :D

So how do the Jap brands stack against the more common ones I see here? Is it purely jap brands are too expensive or are there other issues? How many actually manufacture their own or are just reboxed?

JUN

Tomei

HKS

Wiesco

CP

JE

Arias

ACL

jap brands tend to use the best pick of piston manufacturers and use specific models, ie the trust pistons i use in the top SR's i build use a crown design and special ceramic coated rings only available under license through trust even though the manufacturer makes "other" SR20 pistons.

Arias are a good budget brand and i use them mostly on budget builds but i am not a fan of dished crown in any HOT SR20 i prefer the flater notched crowns, i am currentley building a test engine with SRP (JE). so i will soon know what they are like.

i dont know of any jap manufacturer that manufactures their own pistons but most are made to spec and are not available in another brand or boxes, they are made under license.

Interesting. Personally I am looking at a Tomei forged piston kit for my RB25DET however I'd have other things to sort (like being able to drive while R33 is off the road) before embarking on a full rebuild.

you need to look a a few things to determine whether or not you 'need' the extra benefits offerred by these dearer pistons, on many builds i will talk a customer down and prefer they spen money elsewhere for their application but for extreme and high hp and high rpm i prefer the jap brands as they tend to offer a better life cycle and in SR's they offer a unique crow design and ring combo..... oh and zero noise.

Mostly what people think are a good piston rather than actualy using them but still a bit of info there.

So JUN/Cosworth, HKS, Tomei if you're 'loaded' or chasing big power figures otherswise CP, Arias, Wiseco etc will do the job cheaper. Venolia if you want to brake something.

ACL and CP pistons are both very good pistons for the pricing... I personally prefer ACL as they have a better ring kit... Piston wise they are both very comparable quality....

I'm personally running ACL pistons and have had no problems

you say hks and jun pistons if u chase big "power figures" who said u cant make 1000hp with a set of CP's? a set of well made forgies is what you will need. You can get a rebuild kit from racespec for a couple grand..

i can see where he is comming from though. he said some manufacturers have certain technologys which is only available by licence so you will need to go with the jap brands that have this available to get it.

what has stopped the old boys from making 800hp in a big block v8 n/a?

if you want to have that backing then yeah use jap brands.. but i would only use jap brands if im using a full kit (stroked engine) like full hks, tomeii or nismo.

just talking like this because iv seen ALOT of engines built with arias, acl, cp and wiseco

    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
    • You haven't driven many modern cars then have you? Most of them have sfa steering feel with their stupid electric bullshit steering systems.
