Weighing my options:

1.) Build my S2000 with 600 whp range = estimated $10k+

2.) Purchase a clean hatchback, boost H22 or B18C1 or B18B, 600 whp+ range = $10k or less?

With the FRM in F20c F22c and H22A requiring a sleeve rebuild, I am leaning towards the B series motor for major boost goals.

Hesitant to even crack open F motor since home garage rebuild 'is not recommended'. So the H22A is a nice candidate.

Note: I will be installing and tuning myself so trial/error will mean a possible engine replacement. In terms of my willingness to spend money, I am not looking spend too much due to #Adulting.

Build goal is to run 1/2 mile races, decent decent handling for street, and get those Lambo kills. This turbo build will be a weekend/ non-daily driver.

For previous/current owners who are running boost, are my budget prices accurate? What types of setbacks have you experienced?

Any input would be greatly appreciated.

you should pay a tuner that is experienced and knows the platform and power goals you are going for otherwise you are wasting time/money unless you plan to open a tuning business of your own and want to practice on your car for a while till you nail it.

600WHP can be done on a bone stock F20/F22C with a good tune. Since you're tuning yourself though, you probably won't want to take that risk.

Sleeves with a B or H will be mandatory for 600+, or with a B series engine at the very least CSS.

Your budget is too small when considering the chassis, engine, fuel, EMS, and turbo components needed.

Agreed. It would probably actually cost less in the long run to just have a seasoned tuner tune it.

IMO, a 600hp S2000 and a 600hp FWD Civic are 2 really different animals when it's all said and done.
I've owned a 600+whp D series and own a 600+ whp S2k now. They are just different types of "fast" for me. Both have (had) sleeved blocks... (as far as the S2k goes, the block wasn't the hardest hit $ wise...it was the rear end conversion)

Limited budget, extravagant goals, finicky platforms, beginner build.. What could go wrong?

Depends heavily on which engine. You can easily surpass 15k on any of your chosen platforms, providing you do the work yourself.

With how cheap K24s are at US for 1/2 mile /roll racing it becomes very obvious K24 with a K20A2/Z3 is very capable. EFR9174 was htting full boost at 4500 on a k24 (...)



FWD guys most of the times forget the cost of the rear differential (in europe they use 300zx if i remeber correct and someone did an M5) and axles (it happens with new BMW guys too)

What about boosting a d16 for 400+ hp? What is the budget range?

Is it even worth the time building a sohc?

Autoworks

Building a 400hp D series is a great option...but what is it that YOU really want out of the build?

-D16
-CSS block
-YCP/custom lengh rods
-mini ram
It must be like the best bang for your buck like ever.

Great question. My end goal is to build a high horsepower turbo car (leaning towards civic hatchback or coupe) for weekend (occasional) driving/drag racing/half-mile racing. As mentioned before, this project will be self tuned/built so I will be leaving a generous margin for errors. So a replacement engine is possible.

Any idea on the expected budget range for a 400+ whp turbo d16 setup? Everything prior to chassis modifications and professional tuning to clean up my tuning.


Thanks for your information. This is a great starting point for me and anybody else looking to build a home-built project car.
