Yeah with steel wheels instead of ceramic...

umm, no.

the SR20 exhaust housings have a different flange. (they are T25, GTRs are T3).

aslo, how will swapping housings affect what wheel is on there? the exhaust wheel and compressor wheel are FIXED to a common shaft. replaceing the housings wont do f**k all about that. the ceramic wheel is bonded to the shaft and would be hard to remove in your back yard without the right tools and know how. then once you've done that and want to put your new wheel on you then have to somehow be able to spin it up to 100 000rpm (or some such) so you can balance it.

bottom line? not feasible. sorry.

better and probably cheaper to go to somewhere like GCG and have them rebuild your GTR turbos with steel wheels.

GTR's are not T3.

I am wanting to keep the GTR exhaust housing and mate it to the SR20 carriage and front half. So yes swapping the housing will fix the problem as I'm basically using an SR20 turbo with a GTR exhaust housing.

A bit clearer?

hmm, it seems i am as stupid as I look.

I read it the other way around.

yeah, should work ok. just gotta find 2 S15 turbos then.

BTW, I wasn't trying to say that GTR turbos are T3s I was saying that they flanges are a T3 type flange. maybe I got the number wrong but point is turbos for SR20 and turbos for GTR have different flanges where they bolt to the manifold. won't affect your plan though as you are going to use GTR exhaust housing.

go for it.

And I am saying that they are not. RB20/25/30 are all T3 Flange, GTR's are different. GTR's have the T25/28 exhaust flange.

      An update regarding the registration with the DVLA I sent off the paperwork the day after I collected the car from the port, two weeks later it was all returned with a letter explaining they have rejected the application. This was because the cheque was £20 short for the road tax (I used a price list I found online). Nevermind it is what it is, it was sent back to them the following day with a new cheque. Fast forward another 2 weeks or so, I called them for an update to be told it had been rejected. Yesterday (16th September) I received the documents back along with another letter, this time it was because I didn't put an X in one box on the V750 (personalised number plate certificate), which declared that I had the rights to the personalised number plate. Why this wasn't mentioned in the first rejection letter, I don't know, but it could have saved this headache. The documents were sent back today, so fingers crossed third times a charm and it'll FINALLY be registered on the road just in time for the bad weather (woohoo!) To cheer myself up I lowered the front 25mm, was sick of seeing it sit like a monster truck. No idea how much clearance I'll have getting on and off the driveway, I'll worry about that when I can actually drive it

      You're going to miss not worrying about rust in the strut towers like the Skyline shitboxes out there

      A few little updates that weren't filmed due to not taking long to do or not interesting enough for their own video. My new K&N Air Filter arrived, I went with an RU-4180 which matched the dimensions of the universal cone filter the car originally had.  The battery had gone flat, while that was charging I tidied up the spaghetti wiring at the bulk head and down the sides of the engine Next job was to swap the stereo The Kenwood harness had the female ISO plugs cut off and the male ISO plugs cut off the adaptor loom and joined with bullet connectors. I ordered in a repair loom through work and re-did it all. New Kenwood unit installed (Android Auto, DAB, Bluetooth, Reverse Camera) The bonnet/hood gas struts have been poor since collecting the car. I couldn't find any suitable replacements locally so took a chance on a pair from AliExpress.  The originals don't use a retaining clip to secure the cup onto the ball fixture, would explain why I struggled for 10-15mins trying to pry off the cups. The ball fixtures unscrew using a 12mm spanner, new ones are the same size. Sadly no photo of them fitted, you're not missing much lol The dished Momo steering wheel got replaced with my Momo Tuner, turns out I ordered counter sunk bolts for the horn trim ring (like they normally are for the steering wheel) instead of allen cap (flat seat)  A terrible photo of a Quaife style gear shift knob I've had stashed in my tool box for many years after purchasing the incorrect thread size (I can see a pattern emerging with ordering incorrect parts...) Also threw in a cup holder and a (empty) Boss Coffee can, because why not

      GT-R clearly the better choice! The 300 is certainly not insaly fast but has a decent amount of poke. Does a nice little drift around the corners with a decent amount of throttle. It's VERY predictable in a slide too.  Feels so progressive! People probably presume there's a 25 year old driving it based on my behaviour this week! 🤣

      Yeah Jap import. Fairlady Z then! I'm a bit the same.  They've been on my radar for a fair while but then just impulsively decided to buy one!  Was going to just buy an NA and add turbos to it later but decided to save the f'ing around and just buy the turbo version.
