F20b swap

[rafeykhan]

Hi. I’m planning to swap my d13 with a F20b lsd in my Honda City Type Z (2002). Now the stock output will be around 190-200hp but what could I do more to take it to 400hp while keeping it naturally aspirated.
Thank you

search the highest n/a build of f20b then set your goals. no one had that numbers. between from which city you are? if's your from lahore i can help you.

400hp from F20B? Better go for H22A Dohc better torque and ample power. 400HP on sx8 city is no go.

Thanks Hassan. I’m from Karachi. I’ve been trying to search for fully built engines or tutorials on the same but haven’t been able to find much. If you know of any forums/websites please let me know.

Sorry can’t change the engine. Any input on building it would be appreciated!

[rajaahmed96]

What tranny do you plan to use with F20B Blue Top? What variant of engine are you getting? Manual ones are faster as they are rated at 200HP. Taking F20B to 400hp doesn’t seem doable to me atleast else its your choice, F20B in stock tune in sx8 packs some serious power. You need stiffer chasis and better brakes to control it else it can be a disaster.

I’ve dug up a T2T4 lsd. This will be manual. All the research I’ve done told me it’ll be 200hp but I want to go over at least 300, if not 400.
Yes, brakes, tires they’re all in the pipeline. I know putting this much power inside in my sx8 can be dangerous but I’ll have all safety measures in place.
What do you say?

Keep us posted, I have got the same car.

Turbo would be much easier, allmotor f20b could do around 270hp, but it would be costly. Im not an expert tho.

[Hassan1991]

they are almost same. a little difference of torque due to displacement

honda has the strongest internet society, just write on google or youtube , i have seen tons of video.
a tip "make a hybrid " , and thats why honda is famous for.

F20B is basically destroked H22, it is SiR motor. F20B is 2L motor it was made to compete with Toyota 3SGE Beams which is also 2L category motor. Many parts on F and H are interchangeable, you can use H22 valve train, cam gear and camshafts on F20B. Else you can bore stock F20B block to fit H22 pistons.
F20B block is stronger than H22.

yes i know.

Hi Guys
Plan changed somewhere down the line. Getting swapped with a K24a3 now. The mounting is already in process Alhumdulillah.
Looking forward to any suggestions from you guys.
Thanks!

What is your budget? I am doing this as well and there are many many parts that must be imported to get this working right for power. Also valve terrain cannot simply be swapped from h22 to F20b or vice versa. Only the cams which is blue tinted cams in F20b (aka h22a type s cams and cam gears) can be swapped. The valve diameter is different for both. I have an h22 and F20b sitting outside my house to confirm

[rafeykhan]

I’m not sure if I understand you correctly. But I’m not doing h22 or F20b, I’m doing a k24 now.

[shineonmotors]

I messaged you. I understand what you are doing.
