[black240jl]

ok i have an rb20, i am looking for a turbo that i can replace me stock one with that is an internal wastegated one,, i want a garrett t3 t04e or a garrett t3 none the less, but i cant find one that is internally waste gated, my friend has a garrett t3 and he said its a 48 or 49 trim that seems pretty small to me, what trim is the stock rb20 size, also would my friends turbo work or what other internally waste gated turbo could i use, i would want it the same size as my stock rb20 turbo or jsut a little bigger would be fine, plz help thanks im looking to spend about 600 bucks or so on jsut the turbo..

i was looking at a garrett t3 t04e, can you make them internally wastegated?

i was thinkin of 57trim .63a/r..

whats a good site to buy a garrett t3t04e thats internaly wastegated.?

[Sil240]

I'm running a T3/T4 and I have the ATP ultimate internal Waste Gate.Google it.Or just go to ATP's website

You will need a 5 bolt rear housing for that though.Check garrets website they may sell them internally gated as is.

Google Turbo I'm sure you'll find something

hey thanks i emailed mjmturbo caz i saw they had a few upgrades for the rb25 , thanks

if you upgrade that turbo you WILL need injectors and a tune at the minumum...and most likely a z32 maf.

[black240jl]

yeah yeah def i will, turbos the hard part deciding, im goin with mjmturbos.com, go to the web site and let me know what turbo under the rb25 upgradeswould be the best, im trying to build it to at least 300, hopefully closer to 400, but for now i need help findinga turbo, what one would spool up pretty quick, and also handle 18psi, i wat the t04e housing, let me know thanks

so what im asking is, what turbo out of these choices..

3- http://www.mjmturbos.com/1988300ZX.HTM

thats just a few, let me know thanks im leaning towards the 1st one, let me know thanks

[Carl H]

out of curiousity why are you so focused on pressure (psi), its in EVERY one of your posts.presusure != power, its the airflow the turbo generates that does.in an ideal world you need to find a turbo which flows good air at lowish rpm, but the trade off there is spool time.also any modified stock turbo is gonna suck, no two ways about it...you need to get a turbo that was properly engineered.

[black240jl]

well yes i no but the modded rb25 i just wanna make sure it can handle that , i am gonna run a little more when get injectors, and any modded rb25 turbo is gonna be better than my stock rb20turbo with everyfin cut off.. andif i dont have to fork out the money for a garret i wont lol, so thats why i decided to go with the modded rb25 turbo

seing as these turbos are what im looking at, what would be the best one, i want a 57 trim and the 1st one says its a 50 trim what trim is the 2nd one, do you know,jsut help me out, im tight on money and i need a decent turbo, thanks

[black240jl]

alright ive decided to go with a garrett instead there rb25 upgraded turbos they said are 750 dolars, screw that this garrett is 695, you think it will work good?

whats the reason for a z32 maf? would i have to switch to a z32 maf when i do my turbo/inj upgrade?

That turbo should be fine, I run a 60 trim.

240z4u- what kind of spool times and boost do you see?

I am also trying to decide what turbo to run, i am thinking a 3071wg- the one that bolts up to stock exhaust manifold and down pipe or one of the mjm turbos. The only reason i am leaning towards the gt30 is because i have never heard of mjm turbos. I am looking to do right around 400whp eventually. just 350 or so for now
