Diggin the black on black, looks good. Good luck with the Auto-X.

thanks finishing up some small tidbits before the event .

First auto-x since the rebuild today , did ok car was fun , I missed that low end torque But still always fun driving the FD

<-- my best run wasnt the cleanest

<-- would of been a better run 1.5 seconds quicker bUt i ate a cone . was not opening up enouhg for that turn .

And going a bit sideways after rain

Nice runs. Car sounds healthy.

still has a couple kinks to work out , but yeah sounds good . and TY .

I cant wait to take it out again . I think I was hitting the rear bumpstops on the banked left , so I'm wondering what I should do . car isnt very low to be honest . so I was thinking of stiffening up all the shocks see if that stops it .

When are you seeing full boost on the primary turbo in 2nd gear? You really shouldnt have lost much down low tq with the factory sequential setup.

actcually it seems to spool up kind of slow I remmeber there being more boost earlier .

its hitting full boost for primary at around 3200 rpm I'll double check tomorrow .

and transitions at 4000

I'm gonna check the turbo control actuator this weekend . make sure its working correctly . but I dont know . Like I said seems like boost is taking longer then it should . I have the duty cycle maxed out on the PFC . And I'm pretty sure I dont have a boost leak .

I thought maybe it was because of the ports that it seems to spool up slower . But thats on my list of things to do this weekend .

you might of hit hte nail on the head I just looked at some data logs and it seems like the pre control for the waste gate is opening up at 6 psi . so its acting as though either A the pre control solenoid is not working or B the turbos dont have the restrictor pills .

Yea, even with large porting the stock primary is not effected much on spool. I think it will wake up if you find the issue.

Gonna try some things during my lunch hah ,

I gave it some balls today on the way to work . with 15C intake air temps . it spooled to around 8 then past 2700 started to boost to 11 psi , and then asoon as it hit the transition it hit 14 psi

so something is off .

I hadnt boosted over 5 psi since I was breaking in the engine , apart from 2 days of some tunning after the engine break in that I started boosting a bit more .

AFR's are in the 11.1's to 10.7's in boost above 5 psi , Under 5 psi I have it at 12 afrs .

so still has a long way to go . LOL But hopefully fixing this little issue will help the low end torque . honestly the car reminds me of an RX8 as it is now .

Little update , I swapped the plugs for the wg/pc solenoids to chec kif thats the issue , instead primary boosted to 14 psi , and secondary 10 psi . so seems like one of my solenoids may be bad . gonna test them when I get home

spool is still slower then it used to be though .

I think we discussed it in the past but you would be better served deleting them and running Hallman MBCs.

if it comes to it I will .

I had a spare which I swapped in unfortunately its raining alot so i wont be able to give it a go until it dries up .

Alright so a little update , swapped the solenoids and nothing changed ,

decided to try something

disconnected the pre control actuator vacume hose and drove around .. in second gear full throttle pull from 2k rpms I built 12 psi max . then 10 when transition and instantly to 14 after transition .

so I dont think its the actual boost control system thats causing the issues .

it didn't hit the 10+ psi until after 2800 rpms and never reached the target of 14 psi .

PFC says max it ever hit was .84 on a diff pull

I used to have to turn the duty cycle way down to control primary boost ..

so something is definitely not right .

I think either the pre control is stuck open . Or the turbo control actuator is open fulltime so its trying to spool both turbos from the get go .

It's a simple fix....

DUMP the twins and go single.... DONE !!!!

No I like the twins . Nothing wrong with them . just gotta figure out what is wrong with the vacume system

No point in paying for a conversion to make the same power rather then just fixing the problem

What's wrong with them IS the vacuum system.....not vacume

Constant headaches with that rats nest and ALL those solenoids. A nice small turbo will give you the quick spool and would eliminate ALL the headaches you will constantly have..

I too was reluctant to get rid of my twins, had them for a LONG time till the issues like yours started... no more for me....

take it as you like..... been there done that...

first issues I've had with them . replacing a couple solenoids is a lot cheaper then going to a whole new single turbo system . plus the turbos were just upgraded .

Alright so news update . I got the car lifted and rechecckedc every actuator . and hose . and everything seemed to work , I started the car in neutral .

and recorded the turbo control working

so my question is this ! I disconnected the boost hose andc no boost obviously because car was in neutral . but if the problem is the boost side overpowering the solenoid and causing the actuator to stay open . what if I disconnected the boost side from the actuator it should theoretically work just slower

did the test disconnecting the Boost side solenoid for the turbo control , same issues .

So I'm starting to think this is just a characteristic of the ports ..

beautiful! glad to see you never gave up. reading your thread makes me feel like i can actually go somewhere with mine no matter how discouraging it is at the moment

Thank you , my roads been bumpy LOL But now that its finally running I'm really happy with it . Still gotta tweak things here and there . But car is getting to where I want it . currently I'm working on head room haha ..

My car has an aftermarket moonroof But it takes alot of headroom away which makes it difficult when I wear a helmet so .. .i'm trying to either cut away or remove the lower bracket to fit my helmet hah

I cut away a part but I dont like how it came out .. so i'm trying to remove the bracket But STAR HEADED BOLTS ARRG!

Seems like things are just how they are LOL aslong as I''m over 3k its got decent power so.. just gotta drive faster LOL

ITs been a while BUT there have been some updates

my car has an aftermarket moonroof and its crap it leaks the NONE OEM roof liner dangles all over the place you can see it on most o my videos . and when I wore a helmet the moonroof bracket hit my head so I had to drive like a gangster to keep my head from banging into it. I was fed up haha

ripped my fake head liner off

and this is what was under

Took it all off and found out I could remove the bracket safely so I did! AND VUALA HEADROOM , plus now I got that whole race car gutted interrior look going ... LOL

Pic sucks I know I'll get a better one eventually haha

Now since I've got the motor back i've had to add coolant .. at first I thought it was just air in the system , BUUUT eventually I realized my water pump was leaking ..

Attachment 652770

I didnt think it was the water pump itself rather a gasket .

so took it apart and used some right stuff to redo the gaskets

the waterpump to front cover gasket looked very flimsy and kinda half assed like it was done in a hurry

so I redid it

and also painted the pulleys purple to see how it would look .

Attachment 652771

Looks better then the red I think .. just gotta do the other 2 pulleys . LOL
