Hey guys. Long story short, my turbos are burning oil.
I was thinking of upgrading to jwt 500's or 600's and also getting 2.5 Piping w/SMIC's.

Which should give me a good amount of power, Car currently was dyno tuned at 330rwhp 350trq.
Or should i just go oem turbos, 2.5 piping and maybe manifolds or selin dual intake. oem are like 500, while upgraded ones are roughly 1700+. would love to make 420 rwhp and 450 max.
also looking to add in a stage 1 cam.
sorta thinking this as my newsetup

New oem turbos
2,5 piping smics
Cams ( need to do more research)
and dual intake with maybe some MSP Manis.



winter is coming and now is the perfect opportunity.
what you guys think?

IMO if i were to do it again id stay with the stock ones and have them rebuild and just do manifolds, cams, exhaust etc... 500hp on oem turbos has been seen before. quick spool and decent power, perfect combo unless you are a drag racer.

Personally, I have had my eyes on these for a bit for my turbos which are on the way out:

Cheaper than buying OEM, they are simply OEM turbos with oversized turbines inserted into them. Just requires cores. It also helps that I have an automatic, and plan to change them over to .63 A/R along with manual cams along with my transmission swap...

For what you want out of your car the Z1 GT535R is the best turbo you can get. More power and way faster spool than factory units.
