Hi guys

I'm reinstalling a turbo back exhaust this week and was wondering how difficult it would be to fit an aftermarket exhaust manifold?

I have no idea of the time/difficulty and will be paying workshop time while assisting, so any suggestions would be helpful.

I suppose I should also ask whether its worth doing in the first place?

Thanks in advance.

It would be worth doing if it has to be done. You dont have to do it but if you do you know it will last a lot longer then the current one. It isn't hard to do but if you have no idea how to do it get a mate that may know and if not then it would most likely be best to get a workshop to do it... You also have to watch for if you snap and bolt heads off the dump pipe, If you do you will probably wish you had of taken it to a workshop because there is a bit of ass farting around if you do manage to snap a bolt.

I just put a low-mount stainless one on.

There's a week of evenings gone.. . . . :D

Seriously thoughtless design, I couldn't get a proper go at torquing 2 of the nuts, so I'm just praying they don't work loose. I had to slot-out 7 or 8 of the holes (up to 4mm!) just to get it over the studs, and the collector off cyl.5 fouled the stud & nut, so I had to file the weld seam & some of the pipe off just to get the fv(ker on ! !

am I allowed to say where I got it from? Hello, Legal dept. ! ! ? !

A high-mount would probably fit better, since the pipes aren't so tightly bent & grouped.

I am looking at going a low mount soon, im only going a hi flow so i want to be able to use all the existing exhaust and cooler piping, would be good to know where you got yours from, pm me if you like.

I would have thought that a tuned length manifold that is less restricive would have been more responsive and given a little more power, im only going a high flow so im looking for all the little things that make the car more drivable, the only plans i have so far are the injectors, fuel pump, high flow, low mount manifold and plenum, i already have a power fc, avcr and front mount.

The big question here is Tuned length manifold, so expect to pay the usual $1000 and up, only worth while from the gt30r and up range if you are after that special figure, Standard Log is fine for below that its been proven many times over Although other reputable brands do aid in gaining a better figure, but say that word reputable with good reason, as Above that low mount which has extensive mod to make it fit must have been similar design to an ebay special, and have to say that the low mount designs Do Not actually give much if any results as the hardness to get tuned length room and etc ask 6boost or other guys they may confim that for you.

For your above mods best to upgrade turbo back theres a start fmic another Cams another CAI and with the Highflow you shouldnt need to change either manifolds as both standard items will still give you excellent driveability on there own accord so theres some savings there, then again you can have dif suspension brakes to work on if you would like but unless you are planing on say going gt35r or gt3040 then highmount design external gate is the way to go then maybe change plenum and tb to suit, but at the stage you are at and highflows flowing dependant on what dyno between 240-270 all read different the standard items are fine as is spend money elsewhere.

Plus Added note change in ex manifold will most liklely result in change of turbo dump and front pipe positions as well as lines etc etc.

Hope that helps

One of my mates put a stainless manifold on.

It cracked within a month.

He then put the standard manifold on and the car now makes 270rwkw. Which was much more than he was expecting (he didn't want to go past 240, but got a bonus).

Thanks for the input everyone, very interesting. I'm only in stage 1, so no aftermarket exhaust manifold for me.

I've done two turbo back exhaust installs now and for whatever reason it seems ridiculously easy to shear off the turbo to dump pipe bolts :) as happened again this time.

It was only one bolt and my mechanic reckons it should be fine with all the rest bolted up, seems fine so far.

Do you guys reckon its worth paying someone to drill it out?

Its the one furthest away from the engine, pretty tight but thought someone might be able to get a drill in there...?

Same thing happened to me, i ended up getting rid of it cos of all the hassles, really not worth it if your wanting to stay low mount..

    • You just need to remove the compressor housing, not the entire turbo. I would not be drilling and tapping anything with the housing still on anyways. 
    • So, I put my boat on a boat. First of all, I'm going to come out and say it. Why is Tasmania not considered a holy goal, an apex that all road-legal modified cars go to, to experience? This place is an absolute wonderland of titanic proportions. If people are already getting club runs for once in a lifetime 30 person cruises to Tassy then I've never seemed to see it. It is like someone replaced the entire place with an idyllic wonderland for cars, and all of the people living there with paid actors who are kind, humble, and friendly. Dear god. After doing a lap of almost all of the place I've found that it's a great way to find out all of the little things that the car isn't doing quite right and a great way to figure it all out. All in all, I drove for 4 hours a day for a week and nothing broke. I didn't even need to open the engine bay. This is by all means a great success, but it has left me with a list of things to potentially address. I also now have a 3D printed wheel fitment tool which annoyingly hasn't got any threads in it to actually assemble it. I might be able to tape it together to check the sizing I actually want to use, but it'll likely involving pulling the shocks out to properly measure travel at least at the front, and probably raise the car while I'm at it, at least in the rear. I scraped on quite a few things and I'm not sure how else to go about it. I was taking anything with a bump at what felt like 89 degree angles. And address those 10 other tasks. And wash the car. God damn it is dirty. And somehow, the weather was perfect the entire time - And because I was on the top of Mt Wellington it turns out it was very much about to freeze up there. I did something I typically never do and took some photos up there in what must have been -10 and the foggy felt like suspended ice, rather than mere fog. If you own a car in Australia, you owe it to yourself to do it.
    • Damn that was hilarious, and a bit embarrassing for skylines in general 😂 vintage car life ey. That R33 really stomped. Pretty entertaining stuff
    • Hi, I have a r32 gtr transmission. Does any of you guys have an idea how much power it will hold with the billet center plate and stock gearset? At what power level and use did yours brake with or without billet plate? Thanks, Oystein Lovik
    • Saw this replica police car based on a Mitsubishi Starion XX parked next to a 'police box' (it's literally a box) in Hirohata, Himeji City in Hyogo prefecture the other day. It's owned by Morii-san who is a local Mitsubishi Starion enthusiast. According to a local radio station blog post, he always wanted to make a police car himself based on ones he saw in his favourite Manga comics.  As it's illegal to modify a car to look like a police car and drive on the road, Morii-san tried many times to get permission from Aboshi police station headquarters nearby. They refused initially by after they got tired of that they granted him permission. However, the car can only be displayed on private property and obviously can't be registered as long as the police livery is present. The car was completed at a cost of 1.5 million yen (US$ 10,000) in addition to the car cost. A location was chosen outside Hirohata Police box where the car can easily been seen from the street. Morii-san has two other Starion road cars, both widebody GSR-VRs.
