Yee buddy. Did they give you a month eta for the manifold being out of stock also? How much did you end up paying?

Sorry, I somehow missed this. Anyway, I'm at 60k on the kit and still no issues. I changed the clutch because the stock one was skipping, so I'd say it was because of the turbo.

Can anyone who has the kit tell me if my current 2.5" exhaust will bolt up to the kits downpipe?

Should the kit be able to bolt up to the oem exhaust or do you have to go 3" all the way back?

I'm actually running the OEM cat back and it bolted up with no issues. I had a 3"TBE on but it was just too loud for a DD imho.

Thanks for the info.

Did you go with an aftermarket radiator? Trying to determine what will fit with this kit.

Sent from my Pixel using Tapatalk

Yep, I'm using a Koyo radiator. It fits with the stock fans.

Where you able to keep the oem shroud? I live in AZ so ambient temps get over 110 so I think I'll need some sort of shroud for traffic.

Yes I was

So my installer has the same question. Does anyone know the answer?

I emailed Treadstone as well and will post the response if no one answers here.

Coolant lines are ran from the heater hoses on the firewall.

Turbo is installed and running like a dream.

Seen on FB the kit is 50% off so 2500 $ for an efr turbo kit !

Where is this posted on their facebook?

If it's legit that's an insane deal considering the turbo is $1200 alone.

weird it seems it's gone.

They corrected it. 50% off on all intercooler parts.

seen that, bummer

I went looking for it and no luck seeing anything for the turbo kit.

I haven't provided an update in a while, so here goes. I'm just over 77K miles on my car now, about 75K on the kit. I still haven't had ANY issues with the kit. I recently installed the JDL front/over pipe combo (3" catted) and it bolts up perfectly. I plan on installing and tuning an E85 kit (PTuning) in a couple of weeks. Once I get it completed I'll provide an update on the kit with E85!

I think your kit might be the exception as your maf pipe is a little different to the current kit is that right? The airflow is quite bad at low rpm and traffic, causes quite high trims and jumpiness. The maf position is on a bend :(

Spool is directly related to exhaust volume. Twin turbos cut it in half. True built twin scrolls also cut it in half. With twins you can get the turbo closer to the head which reduces exhaust volume further. Oem's know this but they don't explain it to the general public.

Has little to do with smaller turbo size efficiency.

Bummer man, I have the original version of the JDL auto kit. The MAF positioning is garbage...low speed driveability leaves much to be desired. Someone suggested putting a honeycomb air straightener in the charge pipe...ever heard of this?

A lot of Oem mafs have a screens on the (in) side of the maf. Actually I think the stock air box has air straighteners in it, if I remember correctly. Maybe someone can confirm.
You could move the maf sensor to a straighter section and weld it. I bought the maf mount off ebay. Just drill a hole and weld it on or have it welded.

I have considered this, similar situation. But also i just dont know if I can go through the trouble and effort of tuning it again.. have had so many issues I am tired. It runs now, my trims are a bit crazy, but its on target.

I hear you man, it's a daunting task to throw more variables into the mix. I've been through the gauntlet with this car myself. For the most part, I know how to 'drive around' my areas that buck and hesitate but there are few situations even when throttle input is at steady state at highway speeds that my car bucks. I tell myself that it's not worth going through the hassle...and then everytime I drove a stock twin I think "god damn this car drives flawlessly". I love my powerband but having the shoddy MAF really ruins a lot of the driving experience.

I don't have any straight section....the "straightest" section would be right up by the throttle plate which is not ideal either because the valve motion will cause turbulence. I'm considering just taking my car to a reputable fabricator and seeing if they can make something happen. I don't believe it's just about the MAF being on a bend...it's that it's on a bend plus there is a diameter change in charge piping/plus a nearly 90 degree turn that the pipe smaller in diameter takes to get to the charge pipe. All of the SBD/Greddy/HKS/JDL V2/Blitz/HKS/Zage style kits maf position is not that much different than mine is honestly. But they all have a very flat pipe coming out of the cold side of the intercooler feeding the charge pipe. I believe this has a lot to do with it also.

It's a real shame that these kits aren't tested for this, I've come so far now, with so many revisions that I just need to "be happy". After a blown motor and a million issues, the car is better than it ever was. To go and have somebody make up another pipe that may have same issues isn't worth it for me anymore.

I've reached a point where if it isn't detrimental to my engine, it's not a problem, driving experience is gone. I am privileged to have never driven a stock 86 so i can't compare.....

Yep, mine is the original kit. Not sure why they changed the MAF position tbh.

Yep it's a bummer, I reached out to them a few times and they suggested I go to a fabricator to have it moved or a new pipe made....

If using rom raider
download mafscaling-2.5.1
hopefully your tuned on g rom
log with G SERIES ROM logcfg from this site
load log in mafscaling 2.51
copy corrected maf table, load to rom raider and flash.

I just got this working a couple of days ago and its almost like having a automated tuning ecu.
about 100 times faster than reading logs and correcting each cell.

I'm with ecutek :(

It might work with ecutek I'm not for sure.

I'm sorry but you're wrong. It doesn't have to do with effiiency, it has to do with turbine volume. If you have a smaller volume for the same amount of fluid (exhaust gases) it will spool faster.

That's exactly how twin scrolls are designed. One chamber is smaller, the other larger. One will spool it faster the other will give better top end efficiency with less restriction.

Sorry guys to bring this back up. Did you guys solve the problem with the MAF?


Sent from my iPhone using Tapatalk

Nawe, just has high trims and the occasional buck.

Thanks for the insight. Do you know if other owners besides the OP have the same issue?


Sent from my iPhone using Tapatalk

Not sure, I haven't heard of many people with the kit. Tuner said it was common to this kit, and Treadstone hasn't commented, in fact they are very hard to contact.

Aw shucks. I liked the design of the kit specifically being able to use the FMIC and factory crash bar.


Sent from my iPhone using Tapatalk

I'm going to guess that the whole routing around the crash bar etc is one of the reasons for the turbulent MAF readings. Then again, I'm not an engineer, but I haven't had any solid answers.

Yeah I think you may be right. I think I’m gonna look at the Full-race Borg Warner Kit.
