right i have a s2000 with kings performance stage 3.5 turbo package aem edu 1000cc id injectors holds boost up till about 7000 rpm then increases fast to well over 17 psi when it hits the fuel cut and idears i have tryed with the wastegate ran straight from the turbo housing and still the same ????? also where is the best place to map/set up my car in the uk ????

 

You should move this to the Forced Induction forum. It also wouldn't hurt to post a question regarding a tuner in your local forum.

 

sorry only just got this dont know how to move things and doest have to be local i want most recommended in the country

 

What is your target PSI? You only mention it over boosting to 17psi

 

When you are running a large turbo and set up like the Kings 3.5, you need a very large wastegate if you want to run low boost.

 

has 46 mm wastegate and want around 10/11 psi max for this yea went for this kit as i want more next year with a build engine

 

Bigger gate.

 

only 11psi on a kings 3.5? does the turbo even spool up?

 

had a map emailed from kings so shouldent be the timing thanks for your help i guess ill have to buy another wastegate and run 2?

 

46mm wg should be plenty. problem when running a big free flowing manifold and big turbo (T4) like the kings at low boost is you will boost creep. if you turned it up to 17+ psi you'd be fine and wouldn't creep. thats why you need to match your turbo to your goal.

What turbo do you have? 6266 or bigger?

if you had a T3 flange and a 6266 or smaller turbo you'd be ok running 13-14psi for now. A bb 5857 and my pfab elt manifold at 11psi holds boost great. no creep, i have a tial mvr 44mm. i'm turning it up to 14psi when i retune and i expect it to spool faster and hold steady boost just fine
