awesome who did the ex gate for you? Looks really good. I'll keep an eye out for your results mate I hope your excited

Scotty did!!

Common for them rub on the top guide

Some people remove it

I just space it up with washers and use a s15 chain tensioner as it has finer adjustment otherwise you have to replace the timing chain and guides as it has stretched or the guides are worn and you have to remove the cover to do so which means engine out head off and int sump off

This engine did cost abit of money to build, its worth while taken it back to the engine builder making sure there is nothing going funny. But thanks for the input I will have a S15 tensioner installed.

By the way is the ATR28SS15 installed in yours? How does it feel driving around on road?

Worth taking it back to the engine builder if yours rebuilt not long ago and it's a engine fault

I've been very busy lately and haven't had a chance to put it in yet

will put it in 2-3weeks time

Evo should be tuned wed so should have results to put up

Got the evo 8 tuned today

Made 285awkw on 25.5psi with more in it but tuner was not happy with winding in more boost on stock block

Power was still climbing with more he boost he said

I reckon would have cracked 300kw on 28psi

I'll get a dyno sheet up later

Evo 8 stock block

Fic 1120 cc injectors

Deatchwerks 300 fuel pump rewired

Caltex eflex

K&n panel filter std airbox

Ces racing exhaust turbo back split dump pipe screamer

Gsc s1 cams

Hypergear slss2 hi flow evo 9 turbo 25.5 psi 4400-4500rpm

Edited by hy_rpm

It was a kando evo9 turbo with billet comp before and made 256kw on same boost 25.5psi by 3600rpm

I really want to see the 300kw number so on a rigoli dyno day I'll get him to try 28psi and see if I get there

I should start building evo turbos. :rolleyes:

That configuration stopped making power on a Rb25det at 383rwkws E85 proper manifold and externally gated.

Take 15kws off for factory manifold and 30kws off for internal gate. Then I should have 338rwkws.

Take the Evo's 4WD trans lose (assume identical to a GTR) is 12% then the 285awkws is 319rwkws out of a RB. There should still be another 18kws that you can squeeze out.

I'd like to see a Mivec head on a 6/7/8 engine using the larger aftermarket TS turbine housing . Taos mentioned the losses of std manifolds and IWGs on RBs and I imagine you'd lose a bit more if RB25s didn't have the inlet cam switch even as basic as it is .

Anyhow Mivec tames things down at low revs and I think even in std form one of the cams is hotter than earlier factory ones . Taming down means less loss with healthier turbos but all business when the revs are up and cam timing switches to lets go get em mode .

Evo 9s were getting pretty heavy for a 2L car and Mitsy were using all the easy things to avoid adding more capacity .

Lots of aftermarket manifolds around for Evos now and I think FP is doing a larger bore cast manifold which would be handy if it looks std .

Possibilities .

Didn't you say smaller engines usually make similar outright power but there just need more boost usually

    • Hi, is the HKS  Tower Bar still available ? negotiable ? 🤔
    • 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"
