Hi guys new to all this i want to fit a dump valve to my mr2 turbo rev 2 pls need photos as well would be very help full ? i have a full exhust and filter at the mow!!
what boost can i run ? the car came with a boost gauge and a bleed valve the bull and spring 1 its was all ready fited it seems to boost to around 12 psi then slowly drop to about 9psi the higher the revs go is this ok ? many thanks
you want an Uprated Intercooler if your increasing the boost
oh and Rev2 + Dump Valve dont mix, dont do it. I had one and it sounded great but you loose performance. I went back to the standard recirc dump valve and the response on gear change is very noticable, Stock recirc is the only way forward for Rev1 / 2's
As above, dump valve on a REV1/2 is a bit of a no no!
The boosting sounds right, the CT26 turbo you will have fitted does drop off boost a bit at the top of the rev range.
You wont get any Wastegate chatter / sounds But depending on the air filter you will Get an Amazing Turbo Suction / spooling noise and you will be able to hear the stock recirc valve going off.. I have a HKS Mushroom filter and the sound is amazing from it
