Careful with playing with gap. NGK Coppers = good, but your not running far from stock from what I am seeing so playing around with your gap can be bad. (I cant remember stock gap settings)
I don't see anything, but I assume your running on a stock CT26 and stock injectors? Lots of different...
Wiring the wastegate open today... It should run NA that way. If it spools.. It's going to be either the manifold or the wastegate doing something wonky.
The wastegate has been disassembled and reassembled twice. It looks perfectly fine.
Reg has been doing this for a long time, Anthony has been working on 7ms since the beginning...
They have never seen this happen. It kinda defies logic, because this setup should run perfectly fine.
Lets do some history.. I am providing this so you know what was done as it may shine some light onto the issue....
1. Put in a new shortblock 7MGTE, had the head and block prepped and installed a MHG. At this time added RC 550 injectors and had my engine harness gone through and repaired to...
That's the issue really, the reasons for this to be functioning like this have been looked at and the solutions have been tried. The way it's setup should run properly, but doesn't. So when you crawl backwards, all the parts check out. There are a lot of "maybe"s but at an hourly shop rate...
Already swapped the solenoids. Boost controller was the first thing to eliminate.
With the boost controller disconnected, it boosts "normally" but only runs to a max of 5 psi boost. Already smoke and pressure tested the intercooler and piping as well.
With the boost controller working, the...
That's what I originally thought as well. The 60 mm is based on availability. The part is here so I can use it. If I go 44mm I wait.
So the question is... Will the 60 mm hurt? From what I read (remember I'm not an expert by any stretch if the imagination) overbuilding in this area won't hurt...
Made a decision and bit the bullet... going to have RCTS check the porting on the manifold, and make sure that its at the very least a 44mm port. If not do some mild porting on it. Going to go with the "omg... how much $?" 60 mm wastegate and have the dump tube reintegrated with my 3" vband DP...
Well if the turbo is whining, don't run it. Don't want to suck in some metal fragments and chew up your combustion chambers... Interested in seeing how well ALbert's 60-1 performs though :)
I cant tell you accurately what RPM the low boost comes on because I don't have any dyno sheets in front of me. Will get those today.
The wastegate has been on and off the car four times to examine/test/swap springs. The turbo seems to function properly. (remember though, I am not even close...
I think I am going to just swap out the wastegate with a 60 mm one and be done with it. And the amazing setup has more to do with overall engine performance than with this problem. If you were to take the turbo out of the equation, the 7M is running a lot different than prior to the HKS Vpro...
No, brand new turbo. It works amazing with the setup, only problem is can't control the boost.
Keep in mind, this is RCTS and they have done a lot of Supra setups... Usually 2j though. I think mine will be the fastest mk3 7m they have built. Normally, they setup everything and are adverse to...
Tried that... Only 4-5 psi on spring only. Didn't matter if spring was 10 or 14 lb.
It kinda defies logic. Wastegate is only thing that makes sense, but it's anything but normal. Nice smooth curve though on dyno.. A tad over 300 rwhp at 5 psi.
Not sure if this is correct area because its boost related (thinking as an afterthought... )
So, background (for those that don't know), my car is in the shop and getting tuned/upgraded since June last year. The car has a HKS Fcon Vpro 3.3 (7M chipped) and the boost controller is a HKS EVC-S...
Car was on dyno... 350 rwhp @ 3700 rpm 8 psi... Then two problems... 44mm Tial wastegate stuck open and tire went flat... Won't be done until tomorrow morning now....
All that used t4 setup I bought was garbage.... Nothing used ever goes in my engine bay again.
Because it's being tuned at same time I probably won't have a vid. I can't afford to go sit while it gets tuned AND pay for the tuning... Someone has to work... Lol
