Iv blown the bottom end in my r32 GTR and don't no witch way to go about it, I'm sorta on a tight budget due to jus buying a house, if I should go with a rb30/26 bottom end or just buy a new motor iv had the car for a while but jus sits in the garage 2nd drive I went for 8months after buying the car bang bottom end gone. :(

Havnt had a chance to dyno it or nothing.

Following mods are

Intank walbro 500hp fuel pump

850cc injectors pretty sure

Full 3/half inch exhaust wid aftermarket dumps

-5 turbos

Any one know ruffley what power it would push wid a stock motor and the following mods including a ecu plus a good tune.

& if I was to go rb30 bottom end forged, what adjustments ect I would have to do.

Thanks post-133383-13942935135466_thumb.jpgpost-133383-13942935281152_thumb.jpgpost-133383-13942935621347_thumb.jpg

If your tight, stay 26 bottom end.

Its not exactly simple to fit a 30 in a r32 shell, block sits higher and bonnet closing issues where the turbo badge is on the pipe.

By the time you factor in the adapter plate, welding the rear sump bolt holes, redrilling them, new pickup pipe, some small mods to the block like your knock sensors bolt holes and clearancing for the adapter plate, piping or joiners to reach a bit higher and the fact that its not legal, stay with the 26.

If you spun a bearing, just get another crank with the long nose, some rods and pistons and your done, or just get a second hand working engine from a 33/34 (long nose crank drive) and just keep driving, your old engine being sold should cover the engine swap costs if your paying someone to do it for you.

    • 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.
