Hi guys.

What do you think about this,

A garrett T3/T04e 50 trim stage III turbo on a type 4 2.4 engine.

Specs engine

104 x 71
8.5:1 cr
Webcam 86b

Like tot make 350 / 400 hp


I Am asking this becease I cant afford a gt 30 turbo right now.

Should spool nicely

You will need between 475-550 CFM and 18-22 lbs. boost to make that hp.

From the specs on ATP Turbo it says it is good to 450 hp so you should be good.

Thanks for the info.

Also I found a gtx3076r mamba turbo on Ebay. I make him a offer...will see what will happen with this.

That doesn't read like a 3076 but looks like a 3067 ?
With the small-ish turbine A/R of just 0.64 it seems small overall. Its two sizes smaller then a 3076R..
Not sure if you will reach your 400hp goal with that. Bit restrictive for a 2,4 ltr too I'd say. Maybe you grabbed it too quickly?

[behappy]

Walter you are right it is a 3067r.
Compressor wheel and inlet compressor housing are smaller than the gt3076r.
Dont want to run more than 1. Max. 1.5 bar of boost.
Like to keep the engine in one piece this time.

Was thinking this turbo will give less backpressure and instant spool. (That is what i have read)

[blue thunder]

Compressor exducer should be 76.4mm. Think it is a typo. And with the 11 blade wheel, it is even a GTX3076r. Turbine A/R's are available in .64, .82 and 1.02 AFAIK, so nothing out of the ordinary.
Although .64 will spool a bit faster, it will give the highest backpressure of the lot. Could work out great, as you are not going to push this turbo to the limit.

Cheers,

Robin

Hi Robin.

No typo it is an gtx 3067r turbo. Specs above are correct.
Hoping to make 300HP @ 14.7 psi
Any thing above 300 with more boost will be great, but 300 on the streets is more than enough.

[Wally]

.... 300 on the streets is more than enough.

No, it isn''t
