Hi all,

I have finally gotten around to starting my 25/30 build.

Just using an R32 25DE head.

Unfortunately my 30 block has a few score marks in the bores so I will be getting it honed or bored if it is too far gone.

Main question I have is regarding stock 30e pistons, this build is purely for a bit of fun so I wouldn't expect any great power figure. I am after a set of NA pistons and after searching around precision seems the best option for me. In an older thread prices were posted up which were in the $250 bracket minus rings, I can't find anything near that except for ET pistons which I don't want to use.

Is this the excepted price for these now ?

Any info is much appreciated.

nothing wrong with precision pistons.

i had them in my engine for a few months and i loved them. i pushed them to 310rwkw with the crome molly rings without an issue.

the engine was rebuilt and forged for reasons other then piston/ring failure.

i would use them again.

I made 370- 470rwkw for 2.5yrs with the cast precision(cars auto aswell )..i then had a original alternator fail and cut the pumps under full boost

broke 1 piston other 5 where fine.

Ive also used them in a 5k toyota motor, made 156rkw on 24-25psi,on 98 octane had them in for 7-8ish yrs before i sold motor.

Some people have no luck with them though.

Standard pistons are super strong though if you find a set not to worn!

cheers

Hi there mate,

Im doing the same build with r32 25de head. N/A stock pistons conrods and crankshaft. Just had the ACL race bearings, bottom and mains and ACL cromoly rings. Motor is fully refreshed and is ready to be put together, i did not get the motor balanced as i thought that there is no point as im re-using the same NA internal components, do you guys think i need to be worried?.. has any of you guys done a build without getting the motor balanced?.. cheers

Did you get your motor balanced after the engine build?

    • For these last 7 years of ownership, I've always had to use a small scissor jack under one of the front tow hooks to raise the front just enough so my low-profile jack fits under to reach my subframe jack point. I'm beginning to get annoyed of always having to do this. Are there any lower low-profile jacks that fit under the gtr lip on a dropped car?
    • 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.
