MKTurbo Sale Thread
#2061
Hey guys back again after a retune yesterday. I ended up needing a new fuel pump because my flowforce injectors were almost maxed at the top end from a more than likely old dying fuel pump. Threw in a walbro 255 lph and a new fuel filter and dropped the duty cycle almost 25% at the top end. Also made more power with 244whp/and 217wtq and 251whp/220wtq with my exhaust valve open. So far I'm loving this turbo. Only issue I'm having with this turbo now is that 1 of the 4 bolts that holds the compressor side backing plate to the CHRA stripped out and the other 3 were loose causing oil leak between the chra and the compressor side. Looks like i might be able to use a longer bolt and grab more threads at the bottom. If this doesn't work out then Then im going to start looking into what non china-charger i'll be upgrading to next year.

I removed my AC.
Do you mean the lower radiator hose? Mine is the flyin miata silicone hose. If you mean it goes around the power steering line and bracket (just above the steering rack)? I tried that and the line isnt long enough.
I found an early picture from one of Lar's return lines next to a measuring tape and it read 15" I measure mine and its about 17.5". I spent a bunch of time trying to route it to take up the extra line and it seems the shortest distance is the only way it will go. I even went to a hydraulic shop to see if they could shorten it and they couldnt do it.
Note: DONT force these lines. Theyre stainless steal teflon and if you kink it, the kink will never come out.

I tried going around the lower radiator hose (looping on the driver side then back to the block). I tried looping around the lower power steering but thats a lower position and the hose isnt long enough. The hose really needs a direct route because it isnt flexible enough in such a tight space.

For black Friday I am doing $100 off DIY setups, $150 of intercooler setups, and $250 off complete setups. Most parts are in hand. Currently looking at turn around times of about 2 weeks depending on what you order. Parts are on sale until December 5th.

I've recently developed a problem where my boost is hitting 10psi at like 20% throttle, ebc is set to around 15psi and i never get into boost that early in rpm. This is more noticable under load such as light throttle increase in 4th or 5th gear and the boost needle jumps into positive.
WOT pulls are unchanged, hitting my boost target and no noticable loss of power. No creep or leak just from eyeballing the gauge.
I checked all connectors and vacuum caps/lines everything seems normal. Does this sound like my WGA is taking a ****?
I seem to remember someone replacing their WGA much earlier in this thread. Is a turbosmart WGA a worthwhile investment? If not is there a source for a cheap WGA for this turbo?
Thanks

Not sure I understand exactly, but you can set your EBC not to activate at any throttle position you want with megasquirt.
I am not too far from you and would be happy to help. I have found the wastegate cans to be pretty reliable. I changed mine so I would be able to open it up more than one time.

My EBC setttings in MS have been relatively consistent and unchanged, the only time i tweak it is when the temps drop below 40 and I start hitting overboost protection but then i am only changing the top 2 rows.
The consistency in the EBC settings is why I suspect something mechanical but I'll take a look at the map and see anyways.

Sorry I moved and hadn't updated my location here yet. I'm now in Phoenix.

I'm having the same issue. I emailed Lars asking what he recommended, and his advice was to use the gaskets that came with the turbo along with thin coat of copper gasket sealant. I'm pulling my turbo this afternoon after I get off work and I'll be doing what he recommended when it goes back together a little later this week. I'm also going to use Permatex high temp thread sealant on the bolts that hold the flanges to the turbo. I'm not sure if it's needed, but it can't hurt. I'll let you know if it fixes my leak once I've had a chance to test it out. I'm really hoping that it does; autocross is in two weeks and I need this leak solved before I can sign up.

I'd noticed that prior to putting it all together the first time, and Lars actually mentioned it, as well. I'm going to give the second set of gaskets a try with the copper sealant, and I'm also going to get some washers to go under the allen bolts to help them clamp more evenly. If that doesn't work, I'll figure out which thread my turbo has for the oil feed and get a restrictor fitting that'll work.

I will take a turbo up to the local hydraulic shop sometime soon and see if they can give me the exact fitting and specs for it. If you go that route, you will need to add an oil restrictor.
