Gt4 V's Supra

[Sketchy]

WRC ST205 GT4 had the following parts fitted as standard.

Anti-lag system.

Charge Cooler Radiator Spray bar (External).

Water Injection system. With injector mounted in place of cold start injector (Internal).

None of the above are active.

The anti-lag system is pretty unusable holes in the manifold are blocked off, and if you could get it working it would probably kill your turbo in no time.

The spray bar and water injection systems are both plumbed in inactive. Can be made to work with lots jigery pokery, however the spray bar jets arn't fine enough to create a decent mist so don't work that well.

Homologation rules said that the cars had to have the parts not that they had to work.

Also don't need WI for FMIC for 300+BHP in the ST205, the CT26 rev3/CT20B turbo is still happy boosting at 1.1bar unlike the older rev 2 ct26 which is blowing hot air by that pressure. Would need to start thinking about it if you go much higer though..

Tuning an RSM at 116mph on a Belgian highway is NOT suggested.

But it was fun to watch you try to do it

All the disabled things on a WRC can be enabled.

The antilag reduces a ct20b's life to about 1000 miles.

The spray bar is a good thing to enable so is the injection.

You will need a motec to enable the antilag.

i think 320bhp is the maximum the stock ct20b will flow and the standard charge cooler is good for that at 1.1bar with water injection.

1.2bar is about the line where the pistons melt - as Dawesy will agree ;)

so basicly, water injection, boost controller, induction kit, decat, freeflow exhaust, fuel computer, fuel cut delimiter should see any st205 to 320bhp.

Anything above that will mean FMIC, Hybrid Turbo, Forged Internals etc

God i've missed playing with the 3sgte
