You want to replace just the housing or the entire turbo?

Unless it's a Garrett GT series, HKS etcc... you'd find it VERY hard to find replacement housings for such a turbo.

I'm curious as to where you think you'd be able to "order" a rear housing? They're not the sort of thing like springs or pistons, where you can give specs and they'll machine one up for ya...

If it made that much power there's no chance it's a factory turbo, odds are it's one of these t04e knock offs: http://www.turbobygarrett.com/turbobygarrett/catelog/Turbochargers/BB/T3T4R_757197_4.htm

There's heaps floating around on the net that copy this design, very popular for no name "eBay" turbos. Search for "T3/T4 turbo" on eBay, see for yourself.

p.s. what's a hybrid turbo?

It appears to be some sort of older tech garrett unit, I found some yanks talking about one of the PNs on a US based forum yet stating different trim sizes to your own.

Regardless, if it did 450rwkw on an SR20 theres no way its going to be choking the 3L, simple as that really.

If you want a guaranteed result, your better off buying something else that suits the manifold you already have. If you are yet to make a manifold and were going to make one to suit this turbo, give up while your ahead and start over. The world is your oyster.

As stated, the AR is almost a pointless number to gauge without knowing the turbos specs. To the point that, more 35Rs run .63 rears without issue than 30Rs do and they are actually the same housing on both.

Do it once do it right.

The HKS manifold is a good thing but if its a low mount rather than a high mount you will not have space to run an adapter. Its hard to fit a turbo under the low mount manifolds as it is. If it is a highmount of some sort again you may be hitting the bonnet with an adaptor in place... BUT, a highmount is likely to be stainless which you could just chop off the flange and put the flange you want on it.

You need to decide two things, how much power and how much money. 300rwkw you will be wasting your time with a T4 flanged turbo, 400+rwkw you will be spending 20grand in total to get there.

If its 300 you want, sell the HKS manifold and get something suitable.. Probably a stock manifold to be honest. If you DO want over 400rwkw, hang onto what youve got and get the right turbo. If its a twin scroll manifold then pick up a T04Z or 3788R. Recent results for the 3788R have been very impressive.

Lets just say your an odd ball and want 350rwkw, you can actually get a T4 35R from GCG for $1450, I would say that is a good option.. However a member has recently found a twin scroll 3788R to be about as responsive as single scroll 35R (on a very built *read expensive* setup).. Again it all comes down to BUDGET.

GL anyway, this forum has more info than you will ever need... If the info is on another forum another member will find it and put it here :P

gt35 turbine exducer is only 2.5.

Newer GT garrets have the flare up to 3 inch on the outlet but the older T series turbos just had a straight outlet off the turbine, the flare had to be made in the first part of the dump.

GT35 isnt a 450rwkw turbo though, espesially not on an SR20.

Which is what we're getting at.

Yea that's what I thought but I saw the car it was on and that's what it made. And yea aiming for 400kw its a high Mount manifold will just try an adaptor n see how I go hope it doesn't hit on the bonnet with the 26/30 it's gonna be close I reckon

      In the first photo you posted, the colour of the control arms are the signature colour for Ikeya. Same for the swaybar, signature colour for Whiteline.  I like Hardrace, they also do hardened rubber bushes if your car is mainly a street car.  I like GKTech as well, but they use a lot of rose joints in their stuff so might not be the best choice for everyone.  The system might have been good back in its day, but it's a prehistoric system now. I suspect that most people have removed the HICAS as they want the car to do what they want to do, not what the car wants to do. From what I also understand, it isn't consistent in it's behaviour on track so it's hard to trust the car/know where its absolute limits are for track use.  Having said that, I think the HICAS eliminator kit was the first thing I installed when I bought my car. I don't personally have any experience with the HICAS system on a race track.

      Thanks for the info. Didn’t know I had aftermarket control arms already? Will talk to my garage. What brand would u recommend if I want to play around with my camber more? I would think my camber is around stock level right now or more negative now due to lowering with coilovers. I will be lower her again 1.5 cm to get some more.    also why does everyone like to remove the hicas system? Is it because most don’t work properly anymore or ppl just don’t like them. Mine is functioning as it should be right now.    thanks for the good info

      It looks like you've got Ikeya control arms and an aftermarket sway bar, maybe whiteline?  Or am I just going crazy? lol Unfortunately it won't, but what it will do is look really pretty. That's about all unfortunately.  How much neg camber do you currently have? Generally lowing the car dials in quite a bit of neg camber as it is. If you do go down this path, your best bet is get adjustable arms, toe arms (or preferably a good HICAS elimination kit) and traction rods. With all 3 being adjustable, you'll be able to dial out any bump steer that is introduced by playing with the camber settings.

      Great discussion guys. I just have coil overs in my car right now. Ride is pretty stiff and everything feels very precise and accurate when hitting the corners. I started off with a high level and kept specimen.   the only item I feel I might need to adjust is my camber with control arms or a kit as I might want to tuck in my rims more so there is no rubbing. Otherwise I have not thought too much into it as quite happy with the setup. I think the bushings are all good still.    My motor is currently out now but I have got a nismo front strut bar to install. So that should help with body roll in front.    added a photo of what I started with before the modding or let’s say modernization of parts started. 😂

      Thank you both, much appreciated. Yes, 6k miles, not a typo lol. The underside, engine bay, engine, trunk, interior, etc., look great and super clean, has all the splash guards too. Not sure if you can expand the photos, but the dash pic shows the ODO. She looks brand new, inside and out, even has the original Nissan TV/DVD/Nav head unit; still thinks it's in Tokyo haha! I used to own a '94 MKIV Supra, sadly sold it years ago, but wow I love the Skyline so much! The R34 gets SO much attention here since they just became legal to import last year.
