Modding 2015 Stock Civic

[aryaanhadi]

Hello, I have a 2015 stock honda civic, and I'm wanting to make this car way faster and be ready for the track. I'm thinking of doing an engine swap, some tuning and putting a body kid on it, does anyone know which engine could be put in this, its the oriel vti automatic 1.8 version. Any help would be grearly appreciated.

I wouldn't suggest doing such kind of things to an expensive car like a 9th gen. Civic. You're going to ruin the car's resale and if you really want to go ahead, then swap a K20/K24 into it as it came stock in these Civic's from factory in other countries. Type R versions are very expensive while Accord CL9's K24A3 isn't as expensive and can be easily sourced. With the stock engine, you're not going to make many gains by just adding a cold air intake, headers, downpipe, exhaust and a tune. Turbocharging can be another way as R18Z1 can handle a little amount of boost before it blows up into pieces. There's a video that you can find on youtube by searching 'R18 Civic Turbo Pakistan' for more guidance and potential if R18 engine but I don't know whether the stock 5-speed Prosmatec can handle the torque as the guy did it with a Manual base varient that he bought for 17-18 Lac before.

Hello, I don't have much of a plan to sell this, and if I may ask a question, how much hp at the crank could I get with these K engines (k20/k24) and could I expect to for example beat like a fortuner in a race with this engine. Also would the civic loose it traction control due to imbalance in weight.

[omaruser156370259465]

Type R K20 or K24 produces 220BHP and can destroy any local made car be it fortuner, Hilux or Civic Turbo. Paired with an LSD transmission and stage 1 mods you can extract some good amount of power from it. But Type R engines are rare and expensive. The closest option is K24A3 from CL9 Accord which makes 197 BHP. From traction, you just need to put on some good tyres and do work on suspension as well such as new axels etc and coilovers, strut bars etc etc for stability. And upgrading the breaking setup is very important as well.

Thats Perfect, Thanks for the help
But one more question sorry, would the K24A3stock win against the new 2022 civic rs or just normal 2022 civic
and not a necessary question but would you happen to know the stock K24A3 0-100kmh time ?

[omaruser156370259465]

No problem. K24A3 with Manual gearbox in Rebirth can easily beat a stock Turbo RS Civic but when that car's tuned, it becomes something else to be honest. A tuned 1.5 RS Turbo can then even beat a 300G Mark X handsdown. It wouldn't have any problem in beating a stock RS and would leave the 1.8 Civic in the dust. K24A3 with manual transmission will be around 6.5-7 secs for 0-100. There is a guy who did this swap in his Rebirth in Karachi, you might be able to find the car on Instagram pages even. It's a red Civic Rebirth with a K24 swap. You might face one problem in bypassing the immobilizer though for this swap. @Hassan1991 might be able to guide better than me.

[aryaanhadi]

Would you be any chance know the instagram account with the swapped rebirth? So the stock Manual K24A3 would beat the new 2022 civic right? and I'm assuming if I tune it well then it would even maybe beat a 2022 civic rs. Would I also be able to beat a 300G Marx X if I tune it well? Sorry for so many questions.

[Hassan1991]

I got that guy number. Car was dead dropped.
He was selling his transmission so i came in contact with him but he reverted his discussion as he was unable to sell hondata kpro. He was going back to auto transmission.
If you go with standalone in k series you need tune anyway. In a bone stock setup you can make ~200whp ( depend upon tune ).
You can easily beat stock cars and turbo tuned one if you can drive.
If you have seen a race of 2zzge 86 corolla vs tuned turbo civic. It looks that civic lost but that guy actually caught up in the end. So don't take it easy.
In bypassed immobilizer you will loose.

[omaruser156370259465]

To be honest, with the amount of money you would put into this car, you can easily get an EE80 swapped with 2zz ge or EG Civic with H, F or K series swap. They would be much lighter and faster than the cars you mentioned and in this way, you wouldn't compromise on your Rebirth's reliability and resale. Trust me, these cars are way more fun to drive with these engines.

[aryaanhadi]

So if I can drive well and I tune the K24A3 I could win assuming they haven't bypassed the immobiliser, and if I get a automatic K24A3 and tune it could I still have a chance of winning?

[aryaanhadi]

So your saying i should just buy a new car, I don't really want to buy a new car and if I was going to I would probably go with a rx8 or something that looks more sportier and make it a project car. I dont really have any plan to sell this car. So if I engine swap this with a K24A3 but a automatic one would I loose much speed. And would the 0-60 time be like significantly longer or would it be basically the same ?

[omaruser156370259465]

Automatics are always slower than Manuals unless it's a DCT or some supercar tranny. It would be faster than stock but don't expect wonders with Automatic.

[Hassan1991]

Hondata / ktuner only works on manual transmission. And other standalones as well.
On auto you need to use stock ecu and re-flash it which is quite not easy.
With type R tranny. You can walk stock turbo civic. But tuned one will give you tough time.
Your car is heavy so you need shorter gear ratio. K24a3 came with ast5 6 forward transmission with 4.3 final drive. K20A and K24a2 tranny came with 4.7 final drive.

[aryaanhadi]

So would you recommend a manual K24A3, and if so would you know the estimated cost with installation ?

[Hassan1991]

K24A RBB cost 85k complete.
Ast5 cost 75k if available.
Any lsd tranny cost 125-150k.
Standalone 1-1.5 lac.
No idea about tuning and swap.

[aryaanhadi]

Oh ok thanks perfect, may I ask what you mean by standalone ? And would I need both the AST5 transmission and the lsd transmission ?

[Hassan1991]

Standalone ecu means programmable independent engine control unit or management system.
Prefer shorter ratio. But if you find it expensive then get ast5 or a 5 speed k20z tranny RPD6 tranny. It cost 45-50k and go 5.0 final drive. Very short actually. Also came in reborn.

[aryaanhadi]

Oh ok, what would a 6 speed option be for a K24A3

[Hassan1991]

Ast5 is 6 speed, came in cl9
And other type R and type S transmissions are 6 speed as well.
