i think it really comes down what your block looks like - if you bores are fine, keep the stock pistons - just replace the rings etc. But if you got scarring and sh*t on the bore, then you may want consider a bore out to 86.5mm which will mean A/m pistons.

You've mentioned you want to keep it reliable - although it may cost a bit more, doing a little extra then what your've got listed should give you a fairly bullet proof engine.

are you pulling the engine out before you sent it to the shop or are you getting the workshop to do everything?

This thread has gone from bad to worse.

Now it's up to not using .20thou pistons to save money? Bore and hone is $180!!!! Oversized pistons are the same cost as stock sized.

Would you like to do it once correctly and have it last, or skimp on vital things and be wondering in 6 months why it's died again?

Just save your coin and take it to an RB shop who knows what they're doing, let them do what's needed and then pay the bill.

Edit: not trying to sound like an ass, just seen this happen before.....a lot

Also heres something to consider; there's now going to be tiny bits of bearing material throughout the oil, all of the oil.

So anywhere the oil goes (engine of course but oil cooler too), needs to be cleaned out properly. So cooler core and the part you may not have thought of yet, the head. A head service isn't a big deal while the engine is apart but it's like anything and not free.

If you just pull the engine out, pull the sump off, and try to swap bearings (you'll have to pull the crank out to machine it), then put it all back together the problem is you don't know how much bearing material is in the head waiting to wreck your day soon.

I'm happy to help as I have for others in this position but not if you won't allow it to be done properly the first time.

I am getting a Nissan N1 pump for my build.

But that's just me staying with Nissan parts.

And it can handle the power you want for you build and a lot more if you decide to tune up for more power.

If you have the money go the Tomei or Nitto but as you mentioned cash is a slight issue atm so just go the N1. They are a good pump regardless of some of the things that you might read on the forum about them.

For your power goals it will be perfect and give you room to play with if you decide to down the track.

Ps dont forget your oil restrictor ! :)

I know of at least of 3 people running unmodified N1's in their big single Rb26 drift cars that see regular limiter bashing at high 300 - low 400kw and they do just fine.

Too many people are too quick to bag them out imo.

The car is getting

CP Pistons

Manly Turbo tough rods 1000hp

Tomei Head gasket

Tomei Baffle pan

Mines Cam baffle

Tomei Oil restrictor

ACL bearings

studs

Tomei valve springs

Gates racing timeing belt kit

Gasket kit

probs more that i cant think of but thats the main guts of it. i will see how i go when it gets closer to it, its around about 1k more for the nitto pump if i can strech it out then ill bag that or go the N1 if i cant.

Edited by T4NK

Only alterations might be Nismo belt and Nitto pump.

Ever seen a cutaway comparison of a N1 pump Vs Nitto?

I have an N1 oil pump. It's behaving itself.

My son's VS2 Nur has had its N1 pump changed to a Nitto just for precautionary reasons (by the previous owner).

My $0.02 - I think alot of it comes done to who builds the engine and how anal they are about bearing/general clearences/tolerences. I beleive Its the shock loading caused by excissive clearence between the colour and gears that cause the pumps to fatique crack and fail...This can happen in all pumps, but its more prenounced in the n1's & stockers due to the relative strength of the material (sintered metal vs say en24(or there abouts) for the nitto). One day, i'll sit down and run an FEA analyse on a few of the pump designs to show the weak points in the designs.

However, IMOH all pumps will work in the hands of a compentent engine builder. The tomei/nitto just offer an additional safety factor.

If you do go down the tomie/nitto route, i strongly recommend getting a sump extension to 8L and baffels installed to prevent oil starvation due to the higher pump flow rate.

    • 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.
