Few questions,

1)Would a 3 port boost solenoid hold boost better than the standard one?
2)Is there, realistically, a decent electronic boost controller just for switching between high and low boost setting for under £200?
3)Are there any recommendations on brands?

Cheers,
Tom

 

Yes a 3 port is said to do a better job.
Don't know on the electric controller
And the best is said to be the Perrin.

Hope this helps.

 

Cheers for the info b13bat

Anyone else able to answer Q number 2?

 

A three port needs mapping, don't just fit one for "fun", JGM had one in his "bag" when he mapped mine, just in case it needed it. Mine's a tiny bit lumpy in top gear, but how often do you use high revs in top anyway.

Apexi AVCR is one of the best, try to find a 2nd hand one.

dunx

 

have been using a greddy profec A with out much problem better boost control

 

Apexi Spec R, excellent boost controllers, they are twin solenoid and I have found they hold boost very steady and there are usually second hand ones kicking about for under £200.

 

Gizzmo electronic boost controller is simple and *about* £200 brand new.

 

see harvey performance, they do a good simple cheap 3 port for well under £200. Its a single solenoid but very high quality its a HDI SBC-D-SE. For the money its really good, see this review on a forester install.

edit: I should add that you may need to buy more/better pipework as i found mine a little short and a bit too soft for my chosen install position (lower right of steering column in little cubby hole).

 

Would an ecu controlled 3 port solenoid be any worse than a boost controller such as an avcr?
