Turbo lag....can we improve it?
 

Hi all

I have a my93 wrx with the following:
Z4 ecu with scoobychip
k&n induction
full decat

Now question is the turbo TD05 does not seem to kick in till about 4K. so i was woundering if there is a way for this to be changed? I dont know much about turbo's so go easy on me please!!!

Thanks all

Dawes device, ported headers, decat downpipe or best of all, antilag.

weird it should kick in at 3500 rpm?....[shot in the dark] boost solenoid sticking...do a search on cleaning it.

thx for the replies! i have a full decat Katana and already have cleaned the solenoid valve Mr Smash! but yeah may kick in a little earlier but roughly is about 4K. What are these dawes devices? are they helpful and easy to use & install?

Its a manual boost controller. I used it in the past but opted out of it because I cant be trusted with it. Gives a better response than the boost solenoid to be honest. You can get a new one for 45 quid. Am selling one for 30 though which I used before.

What up-pipe do you have? using a smaller bore will bring the boost in earlyer and with the power you'd be running won't stuggle up top too much.

FYI porting the headers will most probably up the revs that boost comes in at.

thanks for the info much appreciated...
i have a normal up-pipe afaik didnt know you could change it.

I think porting the headers at the moment might be a bit on the expensive side and time consuming at the moment

I going to have a read up on these dawes devices and see if they work ok with me scoobyecu chip i had.

Thanks again

Check that your wastegate is adjusted properly, this can cause slow spool up.
