Have you destroyed a turbo?

Hi, I am new to the forum and would like to know if anyone has destroyed their turbo on a Skyline? I have read a lot about not putting the boost over 12psi, but I am wondering if anyone has done this and caused damage, or whether it is just a myth. I know there has to be a limit at some point, is it 12psi or are there people out there running their stock R33 turbos at 14psi or higher?

What are your stories of disaster.

Mine was running at 13psi quite happily turbo wise, although it was starting to ping a bit too much so had to wind it back to 12psi.

12psi I'd say is perfectly safe as long as you have a good tune and decent FMIC. My high boost has been that or 9 months or so with no adverse effects and some pretty hard driving occasionally. Depends whether its a series 1 or series 2 turbo.

As mine is a daily driver i often just run stock boost to and from places, so i wouldn't say i run 12psi all the time. People will also argue whether 10-11psi is more optimal in terms of overall performance too.

I have a R33 Series 1 and have been running 14psi for around 2 1/2 years now. The only problem I have had is the turbo sucked in and ate the rubber bung that the car yard put on to block the Bov return hose when fitting the atmo venting BOV. The same turbo is still on and going strong.

The previous owner of my car destroyed the stock turbo doing 15psi on his daily commutes to brisbane...tortured, replaced, and hi-flowed it in the end...saved me some big money :)

It runs 10psi now for daily driving, but can go up to 18psi, no sweat. Right now, that figure is a little too far fetched though

Skylines have been found by a lot of people to make better, more 'useable' power on around 10-12psi. Note 'useable'... No point running more boost if it aint doing much or downgrading performance and reliability. The fact of the matter is if you are going to boost, you need to mod and free up the airflow so that it is actually worth boosting in the first place. You'll find obviously that if you run a stock skyline on say 12psi, then have another with a cooler, exhaust, filter and tuned on 8 psi it will run a heap better and harder than the 12psi stocky. Boost does not just = power.

R33's really need an aftermarket ECU to take advantage or should I say unlock some decent power.

200rwkw isn't bad considering its a stock turbo.

The FMIC and ECU make a big difference to the R33's.

R32's pitty its not the same for the R32's. :)

Over 10-12psi the stock ECU starts doing strange power dip things.

I aren't running a computer now with my big turbo, cooler, exhaust blah blah and it still runs pretty damn well considering, however am expected to pick up around 25rwkw from computer they reckon, so on about 15psi tuned they said i can look at around 235-240rwkw which aint too bad :) But yes they do need a computer to run well, without one they jsut eat fuel and run very rich. Not good on the wallet believe me ha ha.

Ive seen alot of people recommend this: https://frenchysperformancegarage.com/products/fpg-nissan-skyline-r33-r34-silvia-s14-s15-billet-fuel-tank-bulkhead-hat-top-an6-with-high-current-connector-apex-2-8-delphi-fpg-100?variant=42873255198898 My current pump that stopped working is aftermarket but I had no relay mod or upgraded connectors.

      It’s new. It’s the cd009. I did take the transmission apart to mill down the bellhousing and had both housings come off the gears so wondering is something isn’t in right. I am running redline. I can get it in gear running too but it’s just not easier and it’s almost like 2, 4, 6, and reverse all the back gears aren’t happy going in

      Got keys and did a walk around the yard planning the landscaping works with the family that I will be doing Main effort: remove all the woodchip in the gardens that are around (attached) to the outside of the house and replace with 10mm blue metal, having woodchip close to the house is a recipe for inviting white ants, currently there are no white ants within the block and I would like to keep it that way I'll be buying some large raised garden beds to grow veggies and stuff, and the woodchip will be mulched with everything else that gets dug up, pulled out, or cut down during works Next will some minor drainage and landscaping maintenance up one side of the house, where the fuse box, AC, and solar stuff will go, about 12 mtrs long by 2 meters wide, I'll break up the soil, add gypsum and then I'll dig in a French drains about 300mm deep x 300mm wide and fill it with agg pipe and blue metal, then level out the whole area with a 50mm layer of blue metal, the soil, whilst currently pretty compacted, will break up well with the gypsum to aid in drainage, I'll then cover the area with a 50mm layer of more blue metal In saying this, the drainage issue is minor, but that little hidden away area down the side is untidy and weedy, and as all of the main elec stuff is there I want it neat and tidy to appease my OCD Again, the material excavated from the French drains with be added to the garden bed mulch, as will some rose bushes and some other crap looking garden plants, and a old apricot tree that is looking worse for wear The apricot tree is currently in a little roundish garden bed that is in the middle of the back yard with few other crappy looking plants around it, that will all be removed, levelled, re-turfed, and is a perfect spot for a hills hoist There is also a area about 3m x 2m between the rear fence and shed that will get some attention, it looks like some stuff was stored there and the grass is dead, that will also get broken up and mulched, and is a prime spot for a pumpkin patch I've guestimated that I'll need: 3 tonnes of blue metal, 12 meters of agg pipe, 5kg of Gypsum, and a hills hoist, so a few bags of concrete as well to set it in place (the house currently has one of those pull out 4 line jobs, whilst it works, I want a retro old school hills hoist), I am also going to run some chickens, there's a great spot for a coop, so a chicken coop to suit 4 of those lovely egg laying bitches will also be on the job card That should keep me busy for a while, and will finish off the back yard ready for a early spring planting of some veggies and berries  Once the main effort is done I'll start out the front, there's a large rock garden that could use some TLC, but that is only minor works Should be fully moved in within 2 weeks, the landscaping works will start then Fun times, retirement is good

      Steps to DIY sanding car back ready for respray....

      It happens, that's what your single stage filler is used for.  If it is still visible after the 3 coats of 2k primer, it will be visible after the paint is laid down.  Its hard to give 100% perfect advice without being there in person, I'm very tempted to say stop where you are, fill your pin holes with a single stage putty first then keep going.
