Don't listen to them arggggh!!

Got 90,xxx+ km's on it? Rebuild it. Simple.

If i see another person spend 10 grand+ on bolt ons im gonna scream. It's just dumb...ull high flow ur turbo, run higher boost, throw an fmic on it, with a decent new exhaust, new ECU and then after u run 20psi thru stock internals u'll wonder why 10,xxx km's later why your bottom end is f**ked.

Be smart. Make yourself a decent building block. Forge ur bottom end, make it strong.

$4k on forged rebuild with new metal head gasket, replace everyting. New bearings, machine ur cranks etc etc.

$900 on PFC (if u can find one)

$700 on a decent FMIC kit. Dont but hybrid generic shit.

$900-$1500 on a decent exhaust.

Once you have done this u can buy a much bigger turbo and gaining power will be easy.

Bolt on, and ull regret it =)

Have a read of this, it'll get you started.

Remember

Turbo + dump - 2300

ECU/tuned - 1800

Tyres - 1500

Diff - 1000

Suspension - around 1500?

I/C - 600

Clutch - 1000

Labour for it all - 2000-2500

Your off and running @ $12,000... so the building of a motor (another 7k) is out of the question.

In the above there is also stuff that i probably have not included so costs could be higher yet

If your being slugged 7k to build a motor ur taking it to the wrong place.

ok, i have the exhaust and intake covered.

* Get front mount

* Boost control and boost increase

* ECU

* New turbo ( GT30R or GT35R maybe)

* up-grade fuel pump

* Up-grade AFM

* Metal Head gasket

* Maybe cam/cam gears

Motor in/out - 1000

Pistons - 1400

Rods - 400 (GTR)

Crank/or machined crank with collar - 800

Upto 3600 before the block is even touched, head gaskets, bearings, new oil pump, etc etc. Mates rates are not counted here im afraid

Either way. IMO, totally not worth building the motor if there is nothing wrong with it.

So many people have made 250rwkw on stock motors and most are still alive.

Tuning is the key to longevity.

Drop the comp via a headgasket and providing the tune is safe there is no reason for it to pop.

If the motor simply gets tired and has a lot of blowby then yes its lived a good life. If it breaks a piston, look at the tuner or yourself for doing something silly with it. Its as simple as that. Its not a perfect world so its up to yourself to ensure the tune is suitable for the conditions. Have it run up on the dyno on a hot and icy cold day.

Without labour (motor in and out) mine essentially cost 3.8k just for the bottom end bits inc. gaskets, forged pistons & std rods.

Rebuild the head, thats another 500 + VRS kit $280 + labour of the motor in and out and it will be up close to 6k if not slightly over by the time you throw fluids in to the motor/gearbox etc.

And thats not including the added expense of GTR Rods and crank collar.

R31Nismoid.. 7k is on the conservative side. :O

Yeh exactly.

It also depends on what he wants to do with the engine. He may not have to change his cranks. Plus labour varies from state to state and region to region dependant on who you use. So for what i got for 4k, in most places would cost 5-6k.

But im a big fan of rebuilding 25s when they near 100,xxx....If u want decent power, make the whole engine fresh, not just the head.

But your right Nismoid, if it aint broke, why fix it? But id still be ripping off the head and looking for those signs that lead towards a future rebuild :O

Edited by Sambo33gtst

i will also be doing this to my R33 in the future and by then im hoping to have most of the bolt ons done so the 10K will go straight to a rebuild or even a RB26 conversion for something diffrent (would have less ks as well)

Some times its good to do the bolt on stuff while you have the cash to throw around.. Then when the motor needs to be rebuilt you are 'forced' to do it..

Well it works well when there's a better half in your life that complains about how much money is spent on the car. :)

Its easier to justify that house redraw or loan to 'fix' a broken motor than it is to buy bolt on parts. :O

How i would spend 10k:

Dont sell the car, Keep the car, rb25det's have lots of potential, and r33's are a great car!

3"dump/front pipe

Highflow cat

Some type of japanese cat back, hks,trust etc

Fmic, its up to you what type you use

Standard airbox with K&N filter, or a decent pod (apexi/hks etc) in a decent cold airbox with good ducting

GCG Highflowed standard turbo

Apexi Power FC

Greddy Profec B Spec 2

Nismo 550cc injectors

Nismo fuel pump/Bosch/gtr etc etc

Upgraded clutch

Get it tuned by someone that is well known and recomended by skyline owners

Some 17" or 18" wheels with 235 or 255 tyres on the back and some decent suspension, upgrade the brake pads.

I didnt quote N.Z prices as aussie prices as obviously going to be different.

Goto nengun, look dream make list and buy!!!

thats the way to do it, oh and to kill the moment of high power to non rebuilt motor, 244 rwkws at 11psi with gt3037proS and spat the little end bearing Oh 130000 km on the clock??

Little advice, do the basics exhaust(done), fmic, suspension, fuel pump, injectors, pfc, pod filter :rofl: , coilpacks, cams, and then tune.

By that time you'll have money left over Get use to the power then do the next stage after you save more money, IE: turbo. and just in case always always save and plan for anything that is unexpected that might happen. Saves the heart ache in the end.

Theres no real way or set way you should follow to do upgrades, but then again, why not have a read of others experiences on here then do a list.

The other advice, unless you know its genuine km's for sure, never take notice of the KMS on the dash

My opinion

Cheers A

    • 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.
