I know their are quite a few pages out there for a G23 build, but the ones out there are not exactly what I want. So, I am making my own. I will try to make this a step by step, with lots of detail so that even a unexperienced person can have a go at it.

*I don't have much free time, so this build will take me quite a while to finish.
*Also, I am posting this guide to keep me motivated, something I need help with.*

What to expect from this build.
1. How to build a G23 Vtec w/ low compression.
2. How to install a Turbo on the G23 Vtech.
3. End Result: A F23A1 block on a 1998 Accord EX 5sp Manual, an H22 head, with a Turbonetics Ball Bearing Turbo.

so with that swap all i need to find is a h22 head with the manifolds then right? also what kind of horsepower am i looking at without the turbo? also my accord is auto

 

good start on a DIY thread!
as for fuel rail you can run stock..no need to spend the extra cash on after market...and something you should know cb7's f22a fuel rails are the same as h22's...the only diff. is where the fuel line hooks up..h22 driver side f22a pass side.
well with the low c/r pistons (stock) don’t expect to see much more that 150-160hp at most and that’s with a tune.
If you are going to go boost you need a 5speed swap...auto trans is crap out on you very very fast. Unless you rebuild the auto for your power goals...and a boosted auto is NO fun to drive (unless you just can't drive a 5 speed for some reason)

 

seeing how i have the f23a1 motor which is rated at 150 hp there is no point in swapping out the head then. what about fixing up my motor now? still new to the accord tuning scene.

 

well when you do go boost you will see much more gains with the DOHC head..hands down. the f23 head will not flow as well as a h22 head. Also with the h22 head you have more tuning abilities since you have two cams that can be tweaked...the g23 set up is great for boost you will have much more top end power than the f23 head can offer. SOHC is for low end DOHC is for high end...when you have a 4cyl turbo you want the high end power. Now with the f23 block you get best of both worlds...you have a nice stroked crank( 97mm crans vs. the h22 90.7mm crank) and a head that is good for high end..that’s the whole point of a g22/g23 engine build
also your 150hp rating is from the crank not the wheels..so your f23 engine is really putting down something like 130hp to the wheels..when I say 150-160hp I mean to the WHEELS not to the crank…very big difference

 

if i do that swap from what i heard is that i would usually have to change the water pump is that true? also would it be worth just doing that h22 tranny swap also? im on a low budget so im tryin to make it all work. right now i am having trouble with my car. it keeps reving by itself so i figured it be the o2 sensor so i replaced the up stream and down stream but that didnt do the trick so i brought it in and the shop told me it was the egr valve and deleted the code and told me the problem should go away but still acting up so let me know if u do

 

you need to take a h22 water pump gear and press it onto a f23 water pump.
As for the revving thing...maybe vacuum leak

yes the h22 5 spped swap would be deff. worth it...I'm in the works of doing the same thing as you but with a f22 block...same thing. check out my thread

how is your cb7 driving now with the swap?

 

still workin on the swap...I'm in need for good bit of parts...and my cash flow kinda sucks right now

 

i know what you mean. it sucks but what do you do. since your doing the swap what parts do u need to do the conversion? ive been looking online and there isnt much help with this swap.
