i dont believe in VTA if your running a MAF, so i upgraded to a evo 7 recirculator valve at one point it worked better than stock but still fell to 17 untuned with intake. i sold it a while back now im getting a new turbo possibly a white rabbit i only plan to run 21 psi, do you think a stock evo 9 will work well enough or i should go with something stronger.

 

Yeah....

 

i think you might want to check out a minimum of a JDM MR BOV. or just upgrade to a forge.

Thats just my .02

 

jdm mr dv (bov) the metal one that comes stock will be perfect for you,will hold boost and give you stock like driveability

 

Evo 9? you mean JDM MR BOV. which is made not out of plastic. Yes It will hold 21psi.

 

yea, i have the JDM MR BOV. love it. same drivability as stock, but no leakage like that weak sauce stock one we get over here in the US. plus... its cost effective. no downside there!!

 

JDM MR DV FTW!

there are plenty of places with them in stock.

 

Taper? 20 to 17, right? Thats not the BOV/DV thats the boost sol. taper, unless you have a MBC/EBC, you will have taper. And still some at very high rpms.

 

exuse me, i had the (jdm mr dv) with a hallman mbc and it would not hold. i figured maybe it was my wastegate or a tune could help out alittle, but if others are holding 21 till redline i guess ill buy it again.

 

Hey BLAK, yea i have heard of a few people here and there not holding on it, then go to the forge, then some even went back to another JDM MR BOV and it worked out fine for them. its like theres a select few JDM ones that have little Gremlin's inside. So far.. mines been great tho.

 

Excused.

A list of what you have, or have tried...does wonders when you need help.

Our turbos run out of steam at about 7k. Then they naturally taper.

Maybe you have a boost leak?

 

+1, I have heard this complaint before.

Go with the Forge or APS (Dual Port BOV if you want VTA and RECIR.)

 

+1, Forge and APS are great units. If (more like when) my Greddy goes, Ill be going that route.

 

I've heard soooomtimes the Forge is a little tricky to get dialed in?

True or false?

 

As long as you have the correct spring in, it should only need some fine tuning. Shouldnt be much different than tuning a type-s.

The APS is can also be dialed in.
