So i'm considering turboing my new unmolested Gs-R and i'm hoping for about 300-350whp. Aside from Arp headstuds, eagle rods, and JE 4032 pistons what else should i get to safely make this my DD? Should i get bigger injectors maybe an aftermarket fuel pump? And I also could use help on selecting a turbo as I'm completely out of my league when it comes to them. I want something that spools from about 3k and maxes boost about 4k-4500 but i don't want to lose top end. I was thinking maybe a GT3076R as i heard they spool quickly.

 

You'll have to have bigger injectors and fuel pump to make any kid of power. A gt3076 won't spool that quick but it will close.

 

Do you know of any that spool quicker and what makes a turbo spool faster just for future reference i would like to learn in case i decide to shop for a new one later on. I want the boost early so i as i reach higher rpm's i can keep traction instead of spinning through all of my gears lol. All in all i want a mustang killer. But, keep in mind it will be my DD as i start another project.

 

You can go with a precision sc61 quick power great spool for the power your looking for

 

doesn't a GT30r lag less than a sc61?

 

Sc61s are laggier than **** and really old technology

 

Disco Potato, the GT28RS

 

Yes, you will need to utilize larger injectors, a larger fuel pump and some kind of reputable engine management.

The GT3076R is what I am currently running. I see spool about 3500-4000. Max boost about 5000ish. Although I am running about 9.0:1 C/R and a top-mount manifold.

With your stock 10.4:1 C/R and a shorty ramhorn manifold you should see spool closer to 3100-3300. max boost before 4500rpm.

Not sure what c/r those pistons you mentioned are (im at work, can't look them up) but atleast you will get a general area of spool-up and full boost rpm range.

The 3076R also has no problem holding power all the way to 9000-9500rpm and is a great all-around performer with room for you to bump up the power if need. It also sounds like a diesel truck spooling up aswell which is always nice to listen to.

 

Thanks, all i've heard is good when it comes to the GT3076R and just wanted to confirm the whole top end problem. If anybody has any other suggestions as to parts i should add with the turbo let me know as when it comes to turbos i know NOTHING lol.

 

If you want a faster spoolup try the Gt 3071r or the Gtx 3071r

 

Either one of these would be a great choice. Also, the GT2860r would one to look at. Your goals are very realistic given the engine build, but for the utmost streetability, i would go with a T3 flanged GT2871r or GT2860r
