So we asked ATP which turbo for 350-400whp for an rb20 and they recommended a-

[SuicidnS13]

I asked them for a 350-400whp responsive turbo setup under $1k. They emailed me back this recommendation-

T3/T4 60-1 with a stage III in a .63 A/R will do the trick for 350 WHP now and 400WHP later down the road.

Dont you guys think this would be laggier than a 50 trim t3/t4? Or is this actually a good recommendation from them? What do you guys recommend for a daily driven work car looking for 350whp and minimal change in lag.

i think you should be fine. And NO OFFENSE, but you asked a Turbo company what would be good then you doubt it.

whats the difference in the now and later setups?

whats the difference in the now and later setups?

now = whatever you have currentlylater = adding performance parts + complimenting those mods + being able to up boost reliably with supporting mods

(turbo wise^)

[ANVIL]

thats what i was thinking but he didnt really say. id be surprised if you can make 350whp on just a turbo upgrade w/o the supporting mods on an rb20.

you would need at least injectors. thats why i was asking what the difference was, what would it be that would give u 50whp more later.

[wawazat8402]

Forged internals and more boost. You will need larger injectors for 350whp, however, a lot of people (like myself) like to work their way up to a 400hp 240, hahaha.

[Carl H]

stock internals are very strong...they are not the limiting factor...if anything the rod bolts will go before pistons

[DriftingisLame]

I think more than a few of us can say stock pistons arent invincible. A small tuning error will make short work of them.

Tuning is the most important factor. Stock internals are indeed flippin burl.

[Cjmartz2k]

I'm making over 600 at the crank on stock RB25 internals. Like you said, it's all about the tune, although do to a grounding issue, I have knocked the motor probably 10 times or so anywhere's from 60-100 knock count on the PFC. Still going strong. I'm not saying stock is invincible, but saying you need forged internalls for 400rwhp is rediculous.

[SuicidnS13]

Yea 400 whp is pretty easy for an rb20 as long as you have all the supporting mods and an amazing tune. Currently we have 550 injectors and a single walbro setup to go in with the motor. Along with a z32 maf and a chipped ecu. Im hoping with tomei 272 cams I should beable to hit 350whp on pump gas and 400whp on 100 octane later on down the road with a stand alone.
