Upgrading setup (turbo&IC) not a noob, your opinion:

[VRMAN]

Well guys, I am planning on switching to a new setup and was looking for suggestions. I was running the following turbo setup:

PTE SCM32 (54 trim)
Dejontool 2.5" UICP
Dejontool super-sidemount (220% bigger than stock smic)
Dejontool 2.25" LICP

On shitty 91 octane and 19psi I was putting down 309whp so I think that is pretty decent for the amount of boost and octane run. After checking the flow chart on the turbo I see that the 54 isn't exactly optimal for pump gas power and also I was looking to take it another step up in terms of power delivery.

It seems like nowadays, every car is coming with more and more hp out of the box and I don't want to be stuck in car limbo where I am beating every B level car but losing to the C6s and what not. Sooooo, I am looking to upgrade even more for better power delivery. Check my profile for current mods and car. My goal is to increase mid and top end power across the board and still put down good pump gas numbers. Being a GS-T, I don't mind lag but I don't want to wait FOREVER for power. I was hoping you guys could guide me in the direction of making around 400whp with full boost no later than 4200rpms at the latest. Here is what I had my eyes on so far:

TD06h 20G. I would, of course, opt for the biggest MHI wheel they have: The td06h and then have the turbo fully ported both on the inlet and exhaust side. I've heard good things about REAL 20Gs (td06h) both in spool and power.

PTE 60 Trim looks like a great turbo for me. Superior top end that should seperate me from alot of cars on the freeway. Having the cams and ported head has really helped upper rpm flow and I just thought this turbo would compliment my setup well, being a FWD daily driver looking for good power. But then I didn't know if the lag would be way too severe and the 20G might make similar power but with better spool? I don't know, hence my asking.

In regards to the intercooler setup: I have sold the dejontool supersidemount and was looking for a good FMIC for my bigger turbo. First off, I'd like to say that anyone looking to run a T28-16G-18G turbo then that S-SMIC is a perfect fit for you. It cools well up to 350whp and will save you $$ over a big FMIC and also maintain a sort of sleeper status. Pick one up if you run one of those turbos. Anyways, now that I am going with a FMIC, what is a good size core to run. I am looking for something bigger than most street cores but smaller than these titanic "race" cores I see out there. What do you have in mind?

Thanks for the input guys! If you have a turbo you think would be better than let me know!

My "race" core is 24x10x3.5", and I think it's plenty big to cool whatever.

As for turbos, I'd honestly go 60-1/T31 for a decently quick spooling, top end car. 20G's have made power, and so have 60 trims, but the 60-1 will give you good pump gas numbers as well as plenty of room for more power. Actually, a GT30R might be up your alley, too. Look into ball bearing stuff if you want fast spool.

I run 24PSI on the street, and I'm out of injector. That, the stock 1G IM, and the shitty Bullseye exhaust housing are really choking me up top. I can't wait to get my T3 on, and pick up a SMIM to see what the car will really do on pump.

Just my .02.

Ahhh, I dunno about that man. Two of my friends have run properly setup 60-1s before and we didn't like the lag at all. The power is barely more than a 60trim but the spool is way more severe. Don't forget I am running a stock shortblock right now. I've seen 60-1s make good power on stroker motors but even then a 56trim would be a better choice. Same spool but more top end. I think maybe the 60trim is better for what I'm looking to do.

I hit 24PSI in third by 4200. But, to each his own. Also, the 60-1 should have a good bit more in it over a "60-trim."

Edit : This is also on stock shortblock. Like I said, if you want fast spool, a ball bearing turbo is where it's at. Any turbo in the 50 lb/min range should serve you well.
