Searching on this very forum and the very information you seek about the cartridge is here.

The work was done for you 6 years ago.

And yes, 87 in the housing mouth indicates an A/R of 0.87. If it read 68 it would be the smaller 0.68 spec

Most likely it depends on the production run as to what goes on the plate.

Provided it's got the part/assembly number or the cartridge number(as per your build plate), you've got the right spec. Incidentally you will find that number may sometimes be stamped 700177-5003, or 700177-0003. Fishing around brought up the detail both on SAU and another site called Turbomaster in quick order.

I wouldn't be worried about whether it's stamped with GT2835 or not.

Sweet thanks heaps for your reply man... Now for another question and I know I could find it on here but I'll try you first lol... Do you know how much different the larger .87 a/r is in regards to lag/spool response and power than the smaller .68 housing ??

Ballpark figures for a GT3037 are in the order of 500-750rpm, and ~ 15-25rwkW depending on complete setup and tune. Bigger housing will basically push the torque curve to the right so max power figure goes up.

This unit should show a similar characteristic.

The HKS 3037 pro has a bigger turbine wheel than the 2835 but also comes in the .68 or .87 a/r same as 2835......

So would there still be the 500-750 rpm difference ? Might be less?

Would love to see a dyno comparison of the two turbo housings

Ballpark figures I think the 500-750rpm difference will be similar.

If you've got the 0.87 housing it's not going to prove easy to get the smaller one.

Past experience with the 3037 was that the bigger A/R option was better because it hung on and kept the engine making torque at high rpm. The penalty lower down isn't that great, and the bigger A/R still gave wonderfully progressive delivery.

I wouldn't say that the 2835 will be the same, but it will be fairly similar.

      Squeaking clutch/throw out bearing

      By patrickxdf12 · Posted

      Hello!  i just finished manual swaping my r34 skyline with a r33 rb20de box(RB71C)box  When the car is running it squeaks crazy loud and it was smoking from the gearbox area. The gearbox is fine it was tested. The clutch slave cylinder seems like it doesn't fully releases the clutch. I want to ask if this noise is from the throw out bearing or could it be the clutch assembly or disk att.xFliq87Gzw6kImKBVqDebXkj0fBqymk0JaYeP3_3SlM.mp4

      S15 Spec R

      A few small updates since the previous post and lessons. I decided to do a little interior light upgrade on the 110. I quite like the iilumo items, even if they're a bit of a premium over other brands. You'll also note the Stedi Fogs, that will go into the S15 fog lights as I needed to match the bulbs since I got the new ones earlier. I hope they fit as the body is quite a bit longer than your normal bulb.  Annoyingly, I managed to trip the fuse, which normally wouldn't be an issue until I located the fuse. I can't say I've ever come across this. I had lucked out that someone nearby had a spare, but oddly enough Toyota dealerships seem to keep this in stock. I ordered some to keep in my stash and as luck would have it, someone else nearby tripped the same fuse so I passed on the favour.  I also did a little service on the 110 ahead of some additional work coming up. It's been annoying that Goleby's stopped carrying this particular HKS filter for the 110, so now I need to keep them on order from Japan. I also took the opportunity to install a bash plate and number plate riser. The plate riser is such a cheap but nice fix to help really tidy up the car. I'm tempted to now also replace my headlights, on this car. Both items were from Project Aero.    I also needed to replace the rear tyres on the 110, and after trying to get it aligned learnt that I need to replace some bushes in the front end, so that's next.  Closing out this update with a nicer picture as always!
