t3 04e 50 trim .60 compressor .63 turbine

[silviamaniac]

does anyone has hands on experience with this turbo spec

t3/04e 50 trim .60 compressor .63 turbine stageIII 360 thrust bearing.

and what do you guys think about clipping the turbine wheel will do to this turbo.

Pls let me know if you have the exact same spec.

and hav anyone tried the .50 compressor too?

I need hands on experience with this turbo. Thanks

I have heard/seen effiency charts, I'm not sure clipping is a good idea.

i should make my question clearer,

the .50 will it loose breath after mid range to high rpm?the .60 will the boost come in too late?

(base on a ka24de EFI engine.)

---------------------------------------------------------------------------------clipping should increase high rpm HP but increase spool up time.

If .50, loose breat after mid range, clipping sounds good?

If .60, boost comes in late, will clipping make it worse? Thank you.

How much boost do you plan on running???

What ECU and what redline???

IMO, for anything less that 350rwhp, that turbo is PERFECT.

50-trim compressor shines with respect to efficiency, for the KA.

And don't clip the damn thing...buy the proper sized compressor in the 1st place.

Answer my Q's from above and we'll help you make the right choice.

7-10psi with 6btm boost retard module. (.5 - .75 degree retard psi/lb, will set my redline at 6k with MSD RPM module, after that retard)

1st phase will run STRION FMIC, SAFC, STOCK ECU, 370cc SR injector, walbro pump, RH manifold, internally wastegated.

This is at the aim of reaching 250whp without blowing the engine. I believe in constant powerband, i m no into drag racing, preferably utilize the engine + turbo completely without depending on turbo too much.

2nd phase = unknown, might probably get emanage, blow the engine and rebuilt it?? :p

i m still choosing whether a .50 or .60 compressorbut the 50 trim 360 thrust bearing stage3 + .63 turbine is all set.

Thanks for ur advice, Pls enlighten this newbie!

Compressor A/R's aren't really known to have that dramatic an effect on boost response or flow like with the turbine A/R. I'd err on the side of flow though and go with the .60 compressor A/R. Especially since you are using a T3 turbine. They spool up quite quickly regardless of compressor A/R.

I wish I'd had a choice of compressor A/R...I ended up with that exact turbo with the .50 compressor. I think it's capable of making really good power though, We shall soon (or maybe not soon) know.

Doesn't matter...

Get the .60 if you're worried...I have basically the same turbo in 57-trim and make 248rwhp at 8psi.

FYI - Injectors are maxed at 250rwhp - So consider that your upper limit.

Thanks everyone, yeah i was thinking of going .60 too due to future upgrades. Probably a safer choice.

Orion : The SR injectors are cheap budget fix for the moment (poor *** student). BTW, Why did u insisted me not to clip the turbo? Can you explain?? I had the almost everything besides the turbo and piping to finish the job. Wish me luck dude

Thanks for the advice everyone! I m kinda new here and you guys are really helpful! This is my ride! :P

You'll clip it to get more flow...if you need more flow, then buy a different compressor.

Makes no sense to me to buy the wrong compressor only to clip to meet your goals. Buy the right one up front, and you're set...

I am asking this because i got a deal where clipping is free, no matter what turbo i choose. Its at http://www.mjmturbos.com and Jaime is the one i talked to.

He offered 620USD for a t3/04e 50 trim .60 .63 stageIII 360 thrust bearing + free internal adjustable wastegate and clipping if desired and also free water cooled center if you want.

So my question is fairly simple. Since it is free, no reason not to want it, dont you think?

So, i figure, if clipping increases the spool up time, will a .50 cover up the "increased spool up time" and close to a what .60 does, and at the same time i gain a little more high end on the same turbo.

Just a thought, Thanks

[:: orion ::]

If you need/want the flow of a 60-trim, buy a 60-trim...

If not, buy a 50-trim and leave it alone. If you clip it, it'll change the efficiency for the worse...

A 50-trim can support 400rwhp, and still be at ~76% efficiency...how much do you really need???

i mean .50 and .60 on the compressor side

not the 50 or 60 trim. I m sticking to the 50-trim.

i wan the response and efficiency of a 50-trim, the better spool up from a .50 compressor (i think), and also the higher flow at high end power from the clipping process might give.

Its just out of curiousity about the combination, i m planning for 250 at low boost rite now.

[:: orion ::]

You'll notice no diffference in spool between those 2, all other things considered equal. Compressor A/R means pretty much nothing...
