Top mount turbo kit 6 port

[Mnoor786]

Hey guys after 3 years of driving with downpipe tune and exhaust.
Want to do topmount turbo and looking to push 600 to 700 with stock transmission.
What do you guys recommend and supporting mods along with topmount.

I recommend you upgrade your transmission, axles, diff brace and tires before you even start putting a turbo on it.

You will probably need new S58 injectors and upgraded fuel pump....depending if you want to run E or not.

Many people upgrade the turbo, then have the tuner nueter it to keep the transmission from puking.

choose a turbo kit from one of the mainstream choices like KLM, DOC etc.

pair it with a 6870, get an intake manifold and port injection with a motiv reflex controller and upgraded LPFP, catch can unless you want full VTA, PCV block off pins and some meaty tyres

Thinking about doc race its pretty solid kit. Also planning to get catch can. With this much power definitely need some meaty tires haha. Trying to get all the parts on this black friday sale. Hopefully it will be a good one

good call on intake manifold - i forgot that. That should be done even on a stock car.

just dont forget about the block off pins / check valves otherwise if u try make more than 30psi for a duration of time you will kapoot your pcv diaphragm

You can make around 600 wheel with a pure 800 and e30 on stock fueling. My buddy is currently at the level with stock trans and so far so good.

But if you want top mount and fun car to drive I’d go with a 6466. 6870 will be lazier idc what anyone else says. I’m currently north of 800hp on a next gen 6466. I’d recommend port injection, lpfp and reflex but you can get away with just s58 injectors to a limit.

Best advice is pick a tuner and ask them what their thoughts are on what you want to do. You do not need axles, unless you plan to dig race it on prepped surfaces. I run 4.xx second 60-130 on stock axles and suspension with ET street R. Catch cans are pointless. Mine doesn’t catch anything. Intake manifold would be a good upgrade for heat management as well. I also recommend pcv check valves not block off pins. Ross racing sells some. No matter what tho your trans will need to be built.l eventually. Mine started slipping with my hybrid turbo before I went top mount on the 5-6 shift. It’s just a matter of time. Xhp trans tune will help some.
