Hi Zorcain, The trans can handle the abuse I can tell you, but it need some modding The drawback of modding the trans is that you will have to use the manual shifting mode all the time I tried to get some HP/TQ numbers from Virtual Dyno, but the program is not compatible with automatic trans (the torque converter mess up the engine RPM data and render the calculation useless...you will get very high number at the start of the pull, and very low number at the end of the pull) I am presently running 32psi boost (around 450 gram/sec airflow) with a hybrid boost control setup, and the boost response is very aggressive, yet the trans does the job perfectly Note however that I had to adjust the clutch control valves many times to get at the right shift firmness (the TCM adapts to the adjustment of the clutch control valves to try and keep the shift like OEM...you need access ports on the trans cover to be able to adjust the clutch control valves everytime the TCM adapts...at one point you will reach the limit of the TCM adaptability and the shift firmness will remain...at that point you will no longer be able to use the automatic mode) I also fabricated a main pressure control valve with an oversized boost valve to get more line pressure at WOT (I will show you pics and drawing of this valve if you need it) A trans cooler is also very important...I fitted a Derale remote cooler at the back (at the stock muffler location) to keep the trans cool and for the added ATF (the cooler is set at 180F and it regularly engage) You will also need to delete the TCS fuse, otherwise the ECU will close the throttle everytime the tires slip There is also the possibility for some kind of launch control with this car...I recently found out that the ECU uses the Overload ignition timing tables when Brake torquing/boosting...right now I can consistently get 15psi boost in 4 sec with the accelerator pedal to the floor with the brake not failing

You must be maxing out the stock fuel system and relying on your WMI at 450g/sec airflow. I was only hitting around 300g/sec with my previous setup. Are you running 50:50 WMI or 100% methanol? I have used your initial valve body settings and mine is still auto shifting with the stock turbo and shifting better than standard.

![]() Im running a little more than 1000cc/min of 100% meth Glad to hear the initial valve body mods are doing great for your conservative setup ![]() You should tell Mituc to stop messing around and give you more boost ![]() While im here, I will give some update of the big turbo project First I have to tell that the BMW air oil separator is not that great a product...you cant ask a lot from a 25$ parts...i was getting oil in the intake at 32psi and oil in the engine bay when going VTA I temporarily routed the air oil separator outlet under the car for a while, but just bought a Perrin air oil separator (costed an arm and a leg)...the AOS (air oil separator) as coolant ports to prevent it from freezing in winter Thats the AOS in question : https://www.perrin.com/shop/engine/air-oil-separator I also bought this PCV plate : https://www.topspeedparts.com/produc...lock-off-plate I will mod the valve cover breather so it less restrictive and plug it on the AOS A hose coming from the PCV plate will also be routed to the AOS The outlet of the AOS will got to the intake I will delete the oil cap breather...will put back the OEM oil cap The only problem with this setup is that the Forge BPV is VTA, so in vacuum the BPV will be venting some crankcase vapor in the engine bay...so it will smell when not moving....I will need the weld a port on the intake so the BPV can be used in recirculation mode (no venting of crankcase in the engine bay) I recently changed my crappy Toyota injector seals for the Corksport seal (2 of the Toyota seals failed real bad) I changed the Bosch intercooler pump for a Mercedes AMG CWA100 pump...had to wire a PWM controller to have the pump run at 100% I didnt like the boost response with the 8psi wastegate setup (everytime I tried a stronger spring setup in the wastegate I got insane boost level with minimum BCS DC), so plugged in my good old Perrin MBC, and use a MAC solenoid plugged with the meth injection controller as a failsafe to get spring pressure (8psi) in case of failure of the meth injection system (the Aquamist HFS4 has a very nice failsafe setup) With the MBC I get a very aggressive boost response...just the way I like it ![]() Not sure I mentioned this before in the thread, but I placed a Derale remote transmission cooler at the position of the stock muffler...the cooler does a great job and prevent the transmission from overheating (I use to get transmission slipping and retarded shift when doing long pull, but no more) I will post some pics later of the mods...

| ![]() ![]() ![]() I have literally just binge read this entire article from start to finish, more forum reading than I've done in over 5 years. You sir, should give yourself a pat on the back for your extraordinary workmanship, determination, patience and the overall build. You're killing it. I would absolutely love to chat with you about a few things pertaining to my own build. @torquemaniac |

If you want to chat you can do it on Facebook (I dont an IG account)...just search for Eric Lanthier (there are 2 turbo on my profile picture) While im here, I will update the thread : In July I started to see a lot of oil coming from the crank breather....did a compression test and cylinder 3 was at 130 (180 all other) After that I did a general checkup of the engine bay and noticed that my turbo was not spooling at idle (it did spool before at idle) Decided to do an turbo rebuilt since I had a kit in hand and knew that the bearing were probably toasted because I stopped doing turbo cooldown after a run a while ago because im lazy (oil cooled turbo) Did the turbo rebuilt, but unfortunately forgot to put the Viton o-ring in the CHRA (it was under a fucking paper in the rebuild package) Comes monday and I go to work like everyday...the car run super great....turbo spool super fast...suddenly the car start to sputter and I see a freakin cloud of smoke behind the car...the turbo was pissing oil in the compressor housing due to the missing o-ring I had to unplug the turbo from the hot pipe and clamp the oil feed line of the turbo to get home...that made a real mess and toasted the bearing, but I made it home with the car Bought another rebuilt kit and did the job right...but the engine have a hard time revving up now and the turbo can barely spool to 2psi After some research I come to the conclusion that the catalytic converter is clogged due to all the oil that passed there from all my mistakes I then plan a full rebuilt and bought stock pistons and all the necessary hardware from SpeedPerformance at a damn good price, and did the engine rebuild in the 3rd week of July (plugged the Perrin air/oil separator at the same time) Engine fired perfectly after the second start and the car ran great through the break-in period Went to a Mazdaspeed meet and people love the car...did some WOT run on the highway with the crew...everything was OK This wednesday I decide to crank the boost to 30 psi (I was at 27 psi, and gradually going back to 33psi as before the rebuilt) and did a fourth gear pull on the highway just before the exit to my workplace...the car was pulling like a beast then suddenly huge cloud of smoke behind the car...like really huge I manage to get at my workplace on inertia alone...stop the car and open the hood...the engine is on fire Finally stopped the fire with water (my never before used fire extinguisher didnt work at all...you can feel its full by weight, but it wont spray at all) The dispstick popped and splashed oil everywhere...not sure if thats why the engine caught fire though I tried to restart the engine but in a matter of seconds there is a monstrous cloud of smoke coming from the tailpipe and behind the engine (and the engine runs very rough...like its dying) The car will be towed at my cousin chalet and will lay there for a while until I decide to bring it back to life In the meantime I am looking to buy a used Mitsubishi Evolution MR I will post form my cells later...

(Thread Starter) | ![]() ![]() ![]() The Supertech have the same CR...here are the pistons I got : https://edgeautosport.com/supertech-...d-6-2006-2007/ Kept the 87.5mm bore...checked the pistons and bore and the piston/wall clearance was spot on...no boring needed, just honing Made my fist oil change this week-end, and I have a small oil leak that seem to be coming form the rear oil seal (between the engine and transmission) Now I need to stop being paranoid and get into boost to test the new engine

| ![]() ![]() ![]() You mean silicone around the rear seal hosing, not the round seal itself ? On the 3, it was silicone for the timing cover that gave me headache...it is hard to put it back without touching anywhere... The clutch can be done without removing the engine but the ''how to'' i found for a 6 was to remove the whole sub frame and suspension along with obviously the t-case and drive shaft to be able to pull off the gearbox....On a rusted car, removing the whole sub frame means some broken bolts, new end link, alignment etc...So maybe removing the whole engine isn't harder than doing this? On the 3 i was able to do it without removing the frame... Anyway, after seeing your piston, i will lift the head of my backup engine to inspect it....i was confident that my fire was because of a frozen pcv but yesterday i took a compression test on it and #2 reported lower than the others and my mastercraft camera isn't clear enough to be sure...

I also have a Mastercraft camera, and you cant see shit with this ![]() It really pisses me off that the seal is leaking...its dripping under the car and it manage to get on my rear bumper (probably from the turbulence when driving) I hope that putting silicone around the seal housing will be enough, but if there is some significant oil pressure there, the silicone wont be enough...I will have to remove the engine ![]()

| ![]() ![]() ![]() Good chances it is just the joint, not the seal. The bottom sealing of these engine is a very bad design.... Have you used something similar to Mazda grey glue or silicone ? I personally used the mazda stuff at first and had to redo the front cover in place because of leaks. The second time, I used ''Right Stuff'' black silicone and it worked a lot better to fill larger hole. Especially the one between the aluminium pan/bloc and the metal hosing of the rear seal... Mazda instructions for the pan seal is to loosen and move slightly away the gearbox to be able to put the pan in between without removing the front cover. I know some put it there without doing it but it give more risks for leaks....

(Thread Starter) | ![]() ![]() ![]() Finally went to the drag strip to test the car (30psi tune) Got a 6.867sec on the 1/8 mile...didnt hold the brake firmly enough (was so nervous) and did a false start because of this (only manage to brake boost to 5-6psi) Did try for another race, but the car misfired badly when brake boosting...removed the spark plug the next day, and found out that the plug in the #3 cylinder had a melted strap This is the same cylinder that experienced pre-ignition last summer and melted the sleeve and piston...this looks like a fueling problem I the tested the compression of the cylinder to make sure the engine was OK, and got the same compression number on all cylinders, but the numbers are pretty low compared to what I had with the OEM pistons last time : 165psi (Supertech) versus 195psi (OEM)

What alloy are the Supertechs? The 2618 alloy pistons may produce weird compression numbers when doing cold compression tests.

| ![]() ![]() ![]() I am not sure about Versatune. But with ATR you can lower the timing of each individual cylinder. You could reduce #3 cylinder timing 2 degrees to keep things less prone to knocking in there if Versatune has that option.

Do you know a diesel shop in the Montreal area that could flow test the engine injectors ?
