Turbo I intend to use is off the 2019+ RDX

still unsure if the turbo will be a direct bolt up as the RDX has a similar single exhaust port like the L15 engine, I’d assume they are different but by Honda dreams it would be a miracle if they are the same since the engine this turbo was removed from is a 2Liter engine

this model turbo is VFT, Variable Flow Turbo that is pressure actuated instead of computer actuated so that should be an added benefit if I can get it to function correctly with the 1.5 liter engine in our cars

as for tuning- I’m intending to run is the ktuner because as far as I’m aware that’s the only simple option available to us, unless someone has set up a piggyback system that can without a doubt say runs reliably and with little headaches ( I’d rather run piggyback speeduino because of the price and modularity but know from what I’ve found it would be a Massive headache because of the complex Honda ECU)

direct injection, is there any way to add more fuel with the stock injectors past the 30% increase Said to be possible for example will increase the pre fuel pressure add more fuel past the 30% Max fuel injection rate We have available to us with ktuner or will I need to go dual injection if that’s the situation it maybe easier to run dual injection and make a custom intake manifold for dual injection or tap the current intake manifold for screw on type injectors and run a stand-alone system for those injectors instead of k tuning it (which means I can use speeduino with it, I see that as a plus in my eyes since who doesn’t want data logging and modularity plus open source technology)

intercooler size to be decided In near future definitely going to be an air 2 air intercooler set up, don’t have one purchased yet, that’s next on my todo list before Ecu purchase



if you guys have any suggestions/ advice I’m all ears for example:

where I should have my oil return lines hook up ( if there’s a location already available or if I’ll have to tap the pan or block)

where I should have the oil feed Line hook up to if there’s already a good spot or I need to mcgyver something for that set up aswell

same with coolant feed and return if you know of the best location I’m all ears

has anyone found a good oem Honda brake caliper upgrade for our cars yet, I’m trying to run as many eom parts as possible from various Honda/ Acura makes and models anything not off the shelf I intend to make myself and I don’t have the tooling/ equipment to be making brake calipers ( if you do I’m impressed and jealous)

looking forward to this project of making the ultimate beater/sleeper fit, as for people of the internet, I know I have a huge amount of labor to do, but I’m a fabricator with experience in carbon fiber and metal fabrication as well as welding... I’m prepared for the burnt gloves and busted knuckles and all the composite splinters in order to gap fools in a 6 speed sleeper....I want this car to have Heavy ek-eg Sleeper Vibes, ready to gap fools on the track and still haul the groceries and work supplies around the city


For a 2L Engine the exhaust flange seems to be smaller then our 1.5 L series, so making a adapter plate shouldn’t be too difficult, biggest worry is the spacing in between engine and fire wall ( I don’t want to move the engine forward but will negotiate the fire wall with a hammer if necessary)

 

I have no answers, but if you find the thread missing, look under GK Fit Modifications...Engine (or close). There may be answers there already.

 

Can't help you at all for engine. Vtec academy seems to think there isn't much of anything to be squeezed out of these motors. Second gen gets access to forged internals and even then those are only touching 170 reliably before exploding.

For brakes, the caliper from the '99-'00 Integra GSR bolts straight in with the original hub mounts. You need a 280mm rotor, napa sells rotors designed for the '06 mini cooper that match out bore and offset and lug spacing. The dust shield will probably need bending to accommodate but the 11 inch pad is something like 40% bigger than the 10.3, stops much harder in my second gen.

 

I don't know the answer, but I'd be looking at whether the Civic injectors and pump will bolt up. The Si can be remapped to something like 230hp without any hardware changes, and there's some guys pushing over 300hp.

 

I’m going to be running dual injection, keeping the original direct injection and adding injection from the intake using threaded injectors
this saves me cost and adds modularity once it’s proven it can be done reliably then piston and rod companies will give us more after market support letting us go lower in compression to make the real power we want. If I wanted to go simple I would go h22 engine swap or k24 block with the k20 heads... I want to push for more aftermarket support by showing how it can be done and for relatively cheap if done right.

 

this is perfect information for my build thank you

I personally think VTEC academy isn’t thinking outside the box enough we have Low compression pistons available but not to the level I want, my theory is prove dual injection can be done and watch manufacturers fill that gap in after market performance low compression pistons and the performance companies make dual injection intake manifolds For the non fabrication savvy individuals

 

If you're going to be upgrading the front brakes, Fastbrakes makes a kit to put rear discs on the GK. Product is great, the customer service is less so- they shipped me everything but half the brake lines, and two months later I still haven't gotten the missing parts. Installed them with replacements made by a local shop, so I can actually speak from experience here.

Last gen Civic Si or RSX base model calipers, just don't use Hawk HP+ pads or you'll get way more squeaking than a street car ought to have. Rotors are redrilled Sentra pieces, so replacements aren't too difficult.

 

will definitely be looking at this before I swap pistons and rods... till then I don’t think I’ll be going past 170hp with the stock rods and pistons... once I get the system set up right and proven reliable I’m looking to companies to make a 8.6:1 compression piston/ rod set up for our cars ( like what’s available for the b16 and b18 set ups )


cause I want stupid boost And dual injection will allow it
