Wiggins do allow for 8degrees of misalignment per clamp (4deg per ferrule) but in my case it doesn't really matter as I am running solid engine mounts [emoji1]

I don't do things by half measure, except for using a NIStune haha

Nistune is the best, especially with the feature pack and a R35 AFM

As a matter of interest Josh, what have you done for solid mounts?

Got my mate to spin up some custom alloy mounts that position the engine as close to the firewall as possible (10mm further back than standard R33 mounts would position it). Will find some pics of them for you.

Wondering if there are any updates on this, would like to see a dyno plot lol. 

Basically in my situation i'm looking for the same thing this guy is. I have a Hypergear SS1.5 and while it makes the power I want I find I really do need power 1000+ rpms earlier. I live in the US and do track and autocross and I find i'm doing autocross way more and I just am out of the power band constantly while when the car was stock I was fine. 

 

I have a FD RX7 that I was going to keep stock but the power on that car if I were to just mod it with stock turbos would be perfect to me. I just want to NOT do that since a completely unmodded mint low mile RX7 is a rarity over here. 

It took a lot of work to get the car running right up to this point and I don't want to replace the engine. If I have to do that i'd just sell the car and use the money from that and put it into the RX7. Which I don't want to do lol.

Hoping to see some results so I can make a decision.

RB25 fixes this.

Not necessarily. In my case part of the reason I want to stay RB20 is because in my autocross class I can run much lower weight with a 2 liter. Also there is another event I participate in that has a separate class for 2l turbos and above 2l. That is the cutoff. Above 2l is against modern V8 cars

There is another class at that same event I could be in for 89 and earlier cars but I would have to increase weight to 3200lbs. 

 

RB25 would be inconvenient. It'sliterally the difference between me facing a C6 z06 Corvette or a S13

Change the rear end gearing.  Make the engine run in its happy zone.  RB20 requires revs.

Finally everything is finished!.............................. Naht.

As is tradition with car builds right near the end i have decided to change a whole heap of things for no reason other than i felt like it. Luckily its really only the ECU and the loom that will be changing, all else will remain the same (with the exception of removing the ABS as the Link can't do that)

Long story short is that everything was in and running using the NIStune and the Garage 7 IPC. Tuned by Jez on 98 octane running 12psi it made 180kw and then went into the shed for the last 9 months as i had lots of other more important stuff going on in my life. Only running such baby boost as this is a 10.5:1 engine and its absolutely begging for E85 and 3x the boost.

To my surprise the car was disgustingly slow. Like honestly beyond belief slow, although this was all just driving around my street unrego'd so never really got up it. But i had forgotten to swap the diff out because it is terribly mismatched to the RB25 gearbox. Diff in it currently is a 3.6 and new diff going in is the more appropriate match for an RB20 being a 4.3 so that should make it feel quite a bit better i would hope. 

Anyway tonight it will get new diff and rego so i  can put some KM on it and then in the next month or two it will get a full rewire, Link Extreme ECU, Plex MicroSDM 100, and as many sensors as i can throw at it. Then off for a full flex tune and hopefully enjoy it over summer!

Post up a graph for this thing.  With only 12psi not that surprising it's making that sort of numbers.  Air mass flow requires some boost, and air comes free!

Gearing will transform the driveability.

No graph but felt somewhat responsive on the street with 9 month old 98 octane in the tank. Drove it for one day and truck crashed into me and wrote the car off. Probably no new updates for a while.

Omg gutted the car was written off? Still no updates to this?

Nothing has happened for a while but it kicked off again recently. Will be same same but different. Complete PRP and MoTeC catalogue thrown at the car. Will keep you updated

    • 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.
