Single Turbo or STi Engine?

[reaperblitz]

lol if you're just concerned about the lateness of your secondary kicking in, get it modded and tuned to run the way you want it via one of the professional workshops.

No point just commiting to something completely different without at least attempting to do a lil bit with what you have yourself

I vote, mod + tune or parallel instead of sequential LOLS..

o btw, i wouldnt be comparing oranges to apples when it comes to sr20dets and ej20s or else you'll be starting up the whole weight to power debate and engine strengths and weaknesses.

it's not just the lateness of the secondary turbo.. mostly want to be different with my legacy.

Well it comes down to what you want in the end. We can all offer advice and support.

With the responses you've got, you have a lot of ideas to go with.

O here's another one - replacement Bigger turbos?

All the best

In my opinion its Single Turbo or you may as well sit in your deck chair with the sprinkler hooked into a petrol bowser and light a cigarrette

To summarise: Single T or you are better off dead! ;D

[Enervated]

If it was single T.. What turbo would you recommend? I was look T3/T4 ?

[rex-leggy]

no t3t4 is a lag monster! tdo6 if you want big power but a td05 will be fine if your looking for medium range power.

just my opinion . td05 will bolt in factory position and will save you alot of fab work ect, can even get tdo6's to fit in factory position i believe.

Could always just get a Ver8 STi engine and drop that in, factory ECU and re-flash (or Link + tune, which ever).

Should fall within $5-7k depending which road you take with the ECU.

Can still sell off the old complete engine to somebody who's lunched theirs, to recoup some costs.

My relatively factory Ver8 STi engine made 236kw atw. And is very drivable with the twin scroll turbo (early power).

Yeah this was what i was orignally thinking,, Would this need the 6 speed gearbox of the STi or would my 5 speed WRX gearbox fit?

And yes theres a WRX gearbox in my legacy

[pl0x]

with 5-7k and your doing the work yourself & getting mates to help etc? (easy nuff to follow the guides here)

I would recommend doing the conversion and a plug in link (standard engine and vfxx turbo),

unless its rev d, then use a wire in storm

Better (cheaper) option would be to buy one already done though

Yes G/B will bolt up fine.

Just make sure you keep your current flywheel, clutch and starter.

Spoke to Possum Bourne Motorsport, They said a v8 sti will fit & bolt straight up, would just need a new ecu & have it all re-wired.

[Dv8er - FSTWRX]

Ideally a new fuel pump too if you want to be on the safe side (Walbro or similar).

Yep. Was gonna do that after I get some suspension.

There's good news on the ECU front. My research has found that a V7 STi ECU is a plug-in fit. You can use it with the stock engine without any extra wires being run but you'll need to set the AVCS targets all to 0 and disable the codes for the missing TGVs
