Work in progress 2003 wrx sti
Hi all, new on here. I had a Subaru turbo 2000 for about two years then about a year ago I decided to change to a 2003 wrx sti uk type.
I bought the car totally standard and in January this year I started thinking about getting some more power, a friend of mine had just had his car remapped and highly recommended talking to Duncan at racedynamix so I asked for Duncan’s advise on how to get around 350 bhp.
With a list of what I would need I started with a full 3” milltek exhaust with high flow sports cat, walbro 255lt fuel pump, aem cold air induction, while the exhaust was being fitted Julian had advised me the headers were blowing and with my remap booked I needed to get them changed quick.
Jon (micared) was very helpful and advised me to contact Harvey smith. The next day I had my GT spec gen 2 headers with DEI heat wrap (which was a work of art) delivered and fitted with an outstanding service from Jon.
Then it was off to see Duncan for the remap, the car was completely different on the drive home and this is the result

That is a really good result for a UK STi Adam, for the mods you have done and retaining the sports CAT. The 2002 UK STi which I had until recently was 335-348 bhp depending on the rollers in use. Similar mods but no CAT.
Do you have or can you get from the RR, a copy of the boost plot?

They certainly were very good figures from the RR day, No wonder you looked so happy

Thanks for that. Your kind comments are appreciated and thanks too for the graph.
From what I can see I think the special 3 bolt uppipe will greatly improve your spool and I am confident that is the case, so much so that I am happy to send you one and you only pay for it once it is fitted. If you are not happy with the result send it back and I will refund your postage. If you keep it £149 plus £12.50 postage.
An easy way to test it if you have a boost guage fitted is to clock where you get 1 bar. 4th gear on a 5 speed or 5th gear on a six speed but it must be done on the same stretch of level road in both directions and you have to do two or three runs to get the turbo hot to get a consistant result.
Just PM or email if you would like to do this at some time in the future.

That's a very good offer Adam, I very much doubt you will be dissapointed with the results.
I fitted Harveys special up-pipe to mine today and immediately felt a difference in early spool and possibly more torque
Really looking forward to seeing the before and after graphs when Duncan maps in it the near future

Just thought I would update this as some thing have changed now, perrin fmic, MD321 t, 650cc injectors, perrin big MAF to go on as it didn’t turn up in time so I have a pipercross on at the moment.
Duncan mapped my car yesterday and the results are much more than I expected, well over 400bhp I will post up graphs after tomorrow as there is a rolling road day so I’m keeping the exact results quite un till after then.
