would you prefer to use the standard ecu controled boost solanoid or an after market manual one such as a turbosmart??

also would a FSE power boost valve type fuel regulator be much better than an ome one? I have these i just dont know if they are worth fitting??


thanks chaps

ok well the motor is a fully forged ,manley/ Mahl ect 2.5 big cams /valves/springs Ported heads Gt35 turbo Hyperflow monster fmic slightly unequal length headers. 3" sports cat system walboro pump.at present it has standerd sti inlet and map it is going for mapping soon so i need to know what will help and what will hinder the mapper,I dont know a great deal as im new to fast scoobys and i have to say that my car even with the standerd map/injectors ect is realy stupidly quick compared to what it was....v3 STI type R

so when you finnished laughing you gonna answer my question...
or dont you know??

I'm not the best person to answer mate but I'm sure people change the boost solenoids. As for the FSE, again not entirely sure if it is better than OE but I had one fitted many years ago to my Calibra and it was worth the money

Thanks Clarkie anyone else got any opinions??

If you have decided who you want to do your mapping, have a word with them. I’m sure they will be happy to advise you on what you will, or won’t need to do prior to your mapping.

FSE regs don't have a very good rep on here, but I don't know how much of that is bitter experience and how much is just pub talk. Most people opt for something a bit meatier hewn out of a huge lump of metal i.e. SARD, Fuelab, SX etc. It looks like you've already got a fairly serious engine spec there so it seems very very odd that it's not mapped up for it all...unless it's just been built and dropped in very recently.

A common mod is to fit an early OE 3-port solenoid for boost control. It works.

With that sort of spec on that car, I would probably opt for a Apexi AVC-R, this includes a 3 port solenoid and allows a very accurate level of boost mapping, including Rpm and gear controlled boost.

New ones are knocking around on ebay for less than £300 nowadays. It would allow your mapper to setup your car finitely and exzctly to how you want it to drive on the road or track/strip.

agree.. although also depends on what ecu is going on the car.


is the turbo internal or external wastegate?

a walbro intank 255lph pump is not going to be man enough for a gt35 btw.

Depends if it's a real GT35 - I've seen too many of these 'GT35's' that manage to bolt to the stock up/downpipes.

As Simon has stated it depends on the ECU being used. If it has good 3d boost control and gear compensators, like both the Simtek and Subaru ECU's, then I'd prefer the ECU having control. If it's running an ECU such as the Apexi Power FC that does not have this functionality I'd prefer an aftermarket boost controller that does, to gain the full benefit of your set-up.

FSE or stock fpr? Depends on your fuel set-up and requirements, an aftermarket FPR can make it easier to switch from series to parallel configuration and can be used to increase fuel pressure.
