Recommended Upgrades Turbo

[Simon C]

FP Green is good if you want to make more power than what a TD05 20G can provide. Although I'd rather have a Garrett GT3071R for that purpose.

[Guest SPANKU]

you guys do remember that hes got a ver4 wrx meaning that the inlet manifold is kinda different and its a b.i.t.ch to put a td05h in unless its been modify to fit a stright pipe instead of the 90 degree. if that makes any since.

a td05 will get you 240kw maybe. but i would get something bigger like a gerrit or something like simon c has, if i have the money

interestingly the party i've been speaking to about the 3071 is good for around 260od.. i thought it might shoot further than that.

[WRXER]

From the examples I've seen it also has been around that mark, the 3076 with .64 housing can get more which is the turbo Im more inclined to purchase further down the track.

and more lag i would assume?

Don't you mean a higher boost threshold?

tomato tomato..?

Not really, more tomato, potato. Totally different.

i.e. my turbo has a rather high boost threshold (~5500 rpm), but its not that laggy at all. If the engine is above the threshold and I am on and off the throttle, the boost response is instant enough for all intents and purposes.

[funkytown]

i get the point but one should go round correcting the plethora of other inconsistent "lag" and "boost threshold" posts then.

[Koom]

I try at times. In general people are too ignorant to learn the correct terms of what they're talking about.

What gearbox are you running?

With such a high threshold you would benefit from gearing it closer, but i suppose you wouldn't want to lose out on Top speed.

or you have a wagon engine.

Its a mixture of parts using a late model 5-speed that I think was from a Forester (had an oil pump in the center diff housing and a code that I couldn't find on the google machine) and it had a 4.444:1 front and a 1.1:1 center. I swapped for an old center housing so I could use a 4.444:1 rear diff and so now the top speed is somewhere around 210-220kph at the redline.

The high threshold is partly due to the short gearing, if I swapped to 4.111 ratios, I reckon it'd drop below 5k as it would load it up more. If you left foot brake it while loading it up, can acheive full boost between 4.5-5k rpm.
