I haven't seen any pop.

In my opinion, what would most likely kill the engine is:

- Not tuned properly resulting in detonation. eg. timing not adjusted correctly, not meeting the fuel requirements, too small injectors and/or fuel pump.

- Inadequate fluid cooling, in particular on the neo's. Dori and I have both discovered how hot the oil temps run on an RB25DE+t Neo. 90 degrees after a 15minute drive to work isn't uncommon, 100degrees after driving on the motorway also not uncommon and it's not quite summer yet. A 13 row oil cooler will help in this area. I should have my kit fitted this week or next and will report back on the results.

- Too high intake temps. A good FMIC will definitely help to reduce intake temps as with 10:1 compression you want to keep things cool.

- Too much boost. Mind you I've seen the likes of WYTSKY running 15PSI through an R33 GTS4 RB25DE, but don't expect a set up like that to be long-term reliable (in my opinion anyways), it's fine if you're looking to rebuild later on. I still think that unless the engine is already in poor shape, you'll probably reach the limits of a stock factory turbo before anything else.

- The driver/owner. Like any car, if you red line it day-in-day-out, don't maintain it, don't give it time before turning off the engine, etc.. you can't expect any car to last long.

Don't skimp on a good tune, have adequate cooling where it's needed most, drive it sensibly (driving it on 7PSI on a daily and having a high boost option for 10-12 isn't going to hurt THAT much now.. ok it does hurt but you get by ok with 7PSI for just commuting to and from work), maintain and service regularly and it should be fine.

Keep in mind that there are drifter's running RB25DE+t's as well. In my opinion, if it can handle the abuse on the track, albeit combined with good cooling solutions to match, then with the above taken into consideration there shouldn't be much of an issue.

If I didn't see it that way, I wouldn't have done the conversion.

sup, top bloke.

i've got RB20de+T

been running for ummmmmmmmmmm

74+118 = ...dont know... not ven a relevant equation try again

118-74 - 44thousand klms

hasn't skipped a beat

there's no reason the engine would pop. it's a nissan, honda i can understand because they're not designed to have turbos added

nissan blocks already have the plumbing there ready to go to my knowledge, the only difference is that the compression of the head is higher. so the response is greater.

take that into consideration however. RESPONSE IS FAR GREATER.

so

response is greater.

do you NEED a massive front mount? no.

do you NEED 880cc injectors? no.

do you NEED a T88 with extenally gated boost gate manifold stainless gold HKS greddy frontpipe manifold turbo turbo kit? no.

in short - if you don't want your motor to go bang

then build the turbo with stock parts - once you've done that, and it works, THEN you can modify it... but my advice is don't go to nengun and ask for a extenally gated boost gate manifold stainless gold HKS greddy frontpipe manifold turbo turbo kit when you're not sure how the engine will handle having a extenally gated boost gate manifold stainless gold HKS greddy frontpipe manifold turbo turbo kit

ps

i was kidding about calling you a top bloke i just thoguht i'd throw it in there for shock value

but yeah

my advice is

do it right the first time, then build up modification parts... oh and DONT LOSE ANYTHING. TAKE NOTES OF EVERYTHING YOU DO. KEEP YOUR NUTS N BOLTS IN THE ONE PLACE. LABEL THEM IF YOU HAVE TO.

2 years and going strong! BIGGGG upgrade commencing in only a few days/week...

I'll show u Nathan, that all our blocks can take that PSI :/ that being said... I don't think ive touched red-line for atleast a month or more... maybe the secret i don't know....honestly i don't need to go over 5,000 on the street...

Can't wait for the new gear to be put in...:)

I'm waiting in anticipation to see what you've got coming! I still think your nuts :/ Any hints on what you've got in store?

You're right about that... since doing my conversion I don't feel the need to rev it out as much anymore for street driving.

I don't doubt that the DE blocks can take the pressure.. it's more a case of how reliable and for how long it can, but yours is living proof that they can take some pretty big boost without giving up the ghost.

good oil, service regularly & god damn good tune is the key.

adam, i am keen also to see whats coming next for ya you crazy bastard.

u still using the 3071?

its a little bigger then that :(

Im waiting on a single part that is being custom made by a machinist to suit

  • 2 weeks later...

yeah ive been eyeing their motors DaGr81 and its pretty good for that price too!

i pumped thru 14.5 psi as i was testing my EBC yesterday and boy it was quick!

no traction on 18x10" work rims on 2nd and 3rd which shocked me so i backed off immediately lol

    • 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.
