Just emailed Brian Crower back and asked whether to use CP or JE and also for more info on their coating products.

I'd just go with the lighter of the two. Otherwise CP seems to be the common choice even for big budget builds.

ACL forged pistons are quite cheap. they are made by mahle (spelling?)

Not technically correct. They are made by ROSS(most will come in a Ross box) in America. I have a set of 4agte ones here at home that are meant to be .020" oversize. But measured near enough STD size after a couple of months on 32psi!! Pins were oval too. And yes we had them hardness tested to see if it was detonation, which it wasn't. Oh and you can only get what they have(ACL) don't do custom stuff. Still an ok product for the PRICE.

P.s pm sent.

Interesting, i had a box here and it actually had mahle on the side. :hmm:

Does someone know what comp height and pin size are on the stock pistons?

 

There is no need to go forged pistons for 6500rpm, lighter is better where

pistons are concerned and some latest tech custom cast pistons are quite

good and even more forgiving than forged in everyday starts ups.

 

I also know of people running 25mm compression height cast pistons with

longer forged rods with good success.

 

There are ka24e pistons which have 34mm pin height and can be taken

down to 31mm inc custom valve recesses and avail from 89mm up.

Maybe the Toyota ones though have even shorter comp height?

with ACL some pistons are from Mahle and some from Ross, depends on the model

I've decided to purchase the CP pistons in std bore 11:1 CR.

 

I'm getting coatings done in Brisbane by Competition coatings.

 

I may see higher rpm someday, maybe not. Either way its an investment that I'm happy to make. Id probably invest in rods if I was to cam it up, but I don't know about it now at this time as it wont see higher rpm than stock, it wont need to with the right inlet and exhaust.

I hope that pm helped a little. Sorry I wasn't able to help you out. Maybe next time.

 

This WILL be a torque monster in a KE. Keen to see it all running.

Yes Stuart your email was helpful.

 

I will go with Carillo.

 

I'm looking at 900.56 US to my door for custom pistons with ceramic and low friction coatings applied, and rings and pins included.

 

Not bad for custom Carillo gear.

 

I'm placing the order now.

Just ordered the custom Carillo Pistons. All paid for.

 

Yippee! Ceramic and low friction skirts too. 11:1 CR and std bore. :dance:

And I just spoke to Rick Sendall who is making the extractors, it goes in in 2 weeks to have the mild steel 4-2-1s made. I will ceramic them too for a few extra hp. Rick is also going to be making the L pipe I need for the oil pickup mod, and moving the drain bung in the sump to the lowest point. If I haven't done it by then I will get him to weld up the inlet aswell. Then i can try and wire the slut. I will need to splurge on an ecu soon aswell. The i will have to start thinking about a cage and preparing a chassis so I don't get into some serious trouble. I'm thinking an AE71 with 9s all round and an f series diff, since I have 2x corona F series sitting there waiting to be raped.

LRS what will the headers cost without the HPC?

Is the AE71 able to be converted to a 2 door by

just changing the centre pillars and doors or

are the 2 door donor or the roofs different?

It is easy 'if' you have all the parts.
