Keeping it on topic.

Legacy GT Jap Spec import 1989 Wagon. "Liberty RS"

1999 GC8/GF WRX Wagon
Current car - Bugeye WRX 5 speed


Sitting in my driveway at the moment:

2001 WRX 5 Speed.
- Front mounted lag creator.
- K&N Hot air induction
- Cusco catch can
- Some silicone pipes
- Genuine STi suspension
- 18" Rims
- 3" exhaust
- Walbro Fuel pump
- Dewinged/repainted boot.
- DIY cold air induction pipe for the above K&N pod.
- Engine changed by previous owner, has a 2005 engine & TD04L Turbo.
- No BOV - big flutter partly due to FMIC.



Future mods:

TD05 series Turbo and possible change back to top mounted intercooler.

Verso or EcuTek tune.

Love the old school RS. I regret never owning one before they got too old.

Awesome cars, similar EJ20T a few things have changed but yeah fantastic cars.

*Updated.


Replacement headlights going in soon.

Triple gauge center pod has arrived. "Still waiting on the gauges"

Is the FMIC a china spec with 30m of piping? or is it the fact that the tiny TD04 hasn't got the guts to fill the pipes, thus creating lag?

EDIT: TD04 flutter/comp surge is fine... its an excuse to upgrade with it goes

I'd say it's a combination of china spec FMIC and a TD04 struggling with the crazy pipe work. I haven't seen many with FMIC pipes that travel the way mine do. "under the battery"

Looking at getting a TD05 soon + a good tune will help a lot!

Wouldn't help being an MY01 with the taller ratios either. Get the pipes shortened and a decent tune in it and I think you'll find most of the problem goes away

It's a fact of life (with FMIC) that extra piping will cause the lag/response slightly, but shouldn't make the TD04 spool as fast as a GT35!

Process West has the SHORTEST piping on the current market: the sacrifice is the sharper bends needed to keep the piping short. But overall good quality gear that has plenty of R&D behind it.

GREDDY/TRUST is a little longer: but has lew harsh bends in the pipe. Same quality as the P-West gear.

The type of core makes just as much difference too. I'd prefer a Greddy FMIC that costs 3x as much than some china boat anchor

Spent some time looking into it and I will be going a TD05H-16g or 18g ( Not looking at a 2nd hand VF or even a new one due to the Cost vs Performance )

If I go with the 18g I will probably bet a PW or AVO TMIC.

+ Tune/Dyno.



* More silicone added.

Not much more going in, this was only done due to the amount of cracked, heat damaged factory pipes.



Must admit that I'm a fan of the silicone pipes! But the wait for them to arive from the UK has been killing me.
