I’ve been scrolling this forum for a while now and even now in 2023 you’re still in here which surprises me, and yes I know this is an old comment but in your opinion, Is boosting an r18 with stock internals worth it?
That’s a subjective ? Honestly, yes and no. What I said above is true how far are you going with this?? What’s your budget are you ready to also replace wearable items as well. Example LCA slave cylinder brakes suspension thermostat to name a few. You just don’t slap a turbo or supercharger on and go. There is a lot that has to come along with it to make it effective
Upgraded clutch 550
Bigger fuel pump 170
Custom headstuds 200
Bbk or better brake pads 400
Guage pod 150
Engine mounts 450
Bigger radiator 170
Tbolt clamps 60
2.5 or 3 exhaust system 600
Turbo kit 3594 add 99 for Rdx 410cc and pigtails
Kraftwerks supercharger kit 4205
Let’s not forget labor if you’re not installing all this yourself which varies by shop.
2500 to install all above
So your looking at
The above is require don’t let others tell you otherwise. I been down this road already. We are not even talking about downtime
As well to get parts in and installation etc. have another car to drive as well. Now when you boost a car other parts will wear down as the car was not intended to be boosted and your handling will be bad as well. Takes to long to shift into gears sooooo Aka mod bug
Megan racing front/rear tie bars
Megan racing hbeam brace
Stoptech steel braided brake lines
Steel braided clutch line
Eibrach sway bars
Stoptech/DBA drilled rotors or slotted
Hybrid racing short shifter
So yes you can do this on stock block but I can guarantee you will blow the motor if you don’t get custom headstuds and you can’t go over or even near 300whp/300tq as you will bend a rod. Ask me how I know lol.
I’m now fully built head fully built Shortblock fully built Mfactory transmission yes with HLSD added waaaaay bigger turbo every suspension mod in the book lol. Monday I’m installing
Megan racing LCA
Megan Racing Rca
Megan racing rear adjustable arms
Torque solutions stiffer exhaust hangers
Why original oem bearings are shot and I hate squeaks and rattles. Also time to get alignment perfect.
So look at the numbers above just to get started if you’re cool with that then welcome to actually modding a car but some of these parts will get discontinued as you’re seeing due to age and EPA. Boost options are drying up Fast for the 8th gen.
Oh and yes I have a back up full Kraftwerks supercharger kit. I’m manual transmission so Turbo all the way I’m going to build my friends auto 8th and use the kit on that should be some fun comparisons
One more thing have a place to get Hot state inspections as well cause after you boost you not passing an inspection since things will need to be tuned out. Most never think of that first.
So ask me anything I’m Truly fully built R18 civic. I’m not talking theory or maybes I have done it. Now I’ll doing it again with auto version all will be the same path just supercharged this time and if you have Choices Always go built motor so you are not limited you can buy entire low mileage r18a long locks for 800 then just upgrade internals and turn up the boost for real power
