forced induction Thoughts on Turbocharging

[remout]

My postings my say "Newbie" but I may have some experience to share.

 

My last "Fun" car was an Audi 225 TT, after extensive research I put together a GTRS Turbo kit. This went from 225hp/240tq up to 380hp/409tq, daily driven without incident. This took many build hours, many software hours and multiple shop trips for Vacuum/Boost leaks. In the end after 3 years of my wife hounding me to sell it I let it go.

What did I learn? NEVER big turbo again…….For a 2002 if I wanted big HP#’s, honestly I would do it easy and just install a Honda F20 and be done. The Turbo route is a much longer and twister way than you may think.

 

What you think:

Turbo

Manifold

Exhaust

Intercooler

Fueling

 

What you don’t realize:

Motor mounts (Full Race with added vibration and sound)

Oil-cooler

Connecting Rods

Pistons

Clutch

Big Brakes All around

Race Brake Pads

Front and Rear Strut brace

Maybe Roll cage for chassis stiffness

Sport seats to hold you in

More fueling cost than you thought

Transmission Mounts

LSD Rear end

Beefier suspension

Full exhaust for flow (2.5 -3”  turbo dependant)

V-Bands for all turbo and exhaust connections

 

Then you can work on your fuel mapping…….

 

So that’s why I say just bolt in the Dreaded F20 for 250hp and 9K redline, with cheap Honda replacement parts

 

FYI: my wife loved the Idea of a 2002

 

Nope, not what I'm thinking at all.

 

I do bring a bit of experience to this project. I raced Formula Mazda for years and also had a SpeedSource 2nd Gen RX7 for track days when open wheel cars were not welcome. My last project was swapping a LS2 into the RX7 and road racing it.
