Dammit, turbo was SO close to being fitted! :(

Compressor housing fouls on the manifold by about 5mm. So will need to get a spacer plate and some extended manifold studs. Other than that it looks like it will be fine. But probably means I'm not going to have it ready for my dyno day :(

mm I remember sending a 15mm spacer plate with the turbo. Please check the box. Also I've left the screamer pipe abit longer then whats required so there will be enough materials for plumb back extension, but other wise it can be cut short.

There's definitely no spacer plate. All that was in the box is the turbo, screamer pipe and the gate. I did think you said the spacer plate came with the turbo which is why I checked, but it definitely didn't.

The screamer pipe is proving to be another challenge. That is pointed straight at my aircon line, I need to chop it and weld another bit onto it to get it to fit nicely. Shouldn't be too hard though.

Ah legendary, that will make everything easy! Thanks mate. Just need to pick up some extended studs and it looks like it will all be perfect. It was so close to fitting, it was disappointing to not be able to get it all going.

So you will send out a 15mm spacer? Just so I know what size studs to get...

from memory the studs from an ea falcon manifold do the trick..any exhaust shop will have some new ones laying around..

just pop one out and take it to them, ask for a longer one..thats all I did anyway.. :thumbsup:

Yeh the studs are no problem, MTQ Engines have them. Just need to know what size.

They are 15mm spacers, you can use stainless or high tensil studs in m10x1.5mm thread x 40mm length. I've got mine from Supercheap auto, they are high tensil hex studs comes in those champion bolts and nuts packs, cut the hex stud head off with a grinder and there's the perfect studs. From memory I've paid $8 for the pack also came with 4x 17mm nuts.

Yea, I pmed him last night for upgrade, I think the new 11 blade prototype SS1PU should work excellently for track work as the power delivery of that is so linear it almost felt like a V8. But not sure if his class restrictions allow complete aftermarket turbos.

Stao, any chance you could send the spacer plate via express post? Just so I still have a chance of making my dyno day... I can pay for the difference.

My upgrade is nearly done however have hit an issue while re fitting the exhaust.

The SS1-PU is longer than the standard turbo so the dump pipe has moved back and no longer lines up with the cat.

Unless we have missed something this makes it definitely not bolt on since we have to now modify the exhaust to make it fit.

There is a thick plate welded on the back of the exhaust housing which I assume was to get the whole turbo the same size as the stock one however it is about 20mm longer.

Any thoughts?

You'll find a C bracket holding the exhaust near the toll shaft. From memory that had to come loose, then the whole exhaust moves back about 1cm, and every thing lines up.

The whole exhaust sits on rubber hangers right, there are plenty of free play. There is bracket that is holding the cat, loose up that bracket and there will be plenty of free play.

I don't normally disconnect the front pipe from the cat. This is how I fit it:

1. Connect the front pipe to the cat

2. Loosen up the C bracket holding the cat to chassis

3. Fit 6 studs and dump gasket on to the rear end of the turbo

4. Fit the turbo onto the dump pipe and loosely tighten the dump nuts

5. Loose fit the turbo onto the manifold and follow the DIY instructions on the water lines.

6. Secure all bolts and nuts

7. Secure the C bracket.

Or this is how my mechanic normally does it:

1. Loosen up the C bracket

2. Disconnect the front pipe from cat

3. Secure the turbo to manifold via diy instructions

4. Secure the dump pipe.

5. Connect the dump pipe to cat.

6. Secure the C bracket

The variance in rear housing protrusion wouldnt throw out the exhaust, as said rubber hangers will flex.

Just loosen off that one a the cat as its a fairly tight one to work with.

Stao what is the exducer size on that turbo? I would like to see one in a .64 SR20 rear on an SR20..

Thanks Stao - we were hoping it would fit by just loosening or modifying the bracket however my unit looks to be approx 20mm to long and it is too far off in terms of length and angle.

I will probably have a flex join fitted with a custom bracket to replace the stock one. This way everything will fit and there will be less stress on the turbo.

The turbo wont have any stress on it mate.... Its a piece of iron bolted to a piece of iron... The stress will be on the rubber joiners..

Just try, everyone else has them work. Yours is no different.

The plate in the back is 15mms , just force it on and tighten all the bolts. No need for any flexible hoses, the rubber hangers holding the exhaust is flexible it self. Turbine housing and manifold is made from casted steel, they are very hard materials, won't stress the turbo.

And Scott the exducer on comp side is 71mm. I think that would be very interesting running on a SR20det motor.

This is an SS1-PU, ive only heard feedback from 1 other person on this forum about this exact turbo and one other with the SS1.5. Most of the guys here have hiflows which use the standard housing. I would love to see dyno results but have not found any of this exact turbo from someone who has it fully tuned. If you hear of any let me know.

Do you have an SS1-PU?

Im not worried about the stress on the actual turbo housing, im talking about stress on the turbo to manifold studs (and the others) They bend, stretch and snap. The exhaust moves around on the hangars when cornering and hence puts stress on the studs. A flex join in the exhaust helps this. Im sure its best to keep weight off the manifold itself as well since rb25 manifolds crack and warp at the best of times.

This is pretty common problem on tracked cars, I dont think its an issue if the car is not used for track/hard cornering all the time.

Stao - from memory the plate welded to mine looks bigger than 15mm. Here is a pic of it (sitting next to a HKS 2530)

    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
    • But first....while I was there, I also swapped across the centre console box for the other style where the AV inputs don't intrude into the (very limited !) space.  Part# was 96926-4GA0A, 284H3-4GA0B, 284H3-4GA0A. (I've already swapped the top 12v socket for a USB bulkhead in this pic, it fit the hole without modification:) Comparison of the 2: Basically to do the console you need to remove the DS and PS side console trim (they slide up and back, held in by clips only) Then remove the back half of the console top trim with the cupholders, pops up, all clips again but be careful at the front as it is pretty flimsy. Then slide the shifter boot down, remove the spring clip, loose it forever somewhere in the car the pull the shift knob off. Remove the tiny plastic piece on DS near "P" and use something thin and long (most screwdrivers won't fit) to push down the interlock and put the shifter down in D for space. There is one screw at the front, then the shifter surround and ashtray lift up. There are 3 or 4 plugs underneath and it is off. Next is the rear cover of the centre console; you need to open the console lid, pop off the trim covering the lid hinge and undo the 2rd screw from the driver's side (the rest all need to come out later so you can do them all now and remove the lid) Then the rear cover unclips (6 clips), start at the top with a trim tool pulling backwards. Once it is off there are 2 screws facing rearwards to remove (need a short phillips for these) and you are done with the rear of the console. There are 4 plugs at the A/V box to unclip Then there are 2 screws at the front of the console, and 2 clips (pull up and back) and the console will come out.
