Well as alot of you know I've always built my cars up, but they have always kind of been my daily so I could really never get too deep into the build cause I needed to get to work on Monday. I know all you guys can understand that, no job no honda.

Just an awesome photo!
Image


This is pretty much how I got the car, but it had some really ugly blue wheels on it so I picked up some si's from a friend so it would atleast look decent for the time being. It's a 98 RS (no sunroof) 5 speed of course, but this RS has power windows. I always thought RS had all manual functions but I was wrong. I don't have any interior photos at the moment but I'll get some.

I don't know why I don't have any photos other than the front end, that's just what I took, but they werent taken with this thread in mind so I'll update it with better photography.

Stage 1: Tear down.
Sold the OEM 98 front end, hood, fenders, bumper, lights.

Old power house!!! 2hours after starting, I love how easy hondas are :)

New shit!
Avid black mounts

What you see here is my cabinet full of goodies, Avid mounts, type-S oil pump, type s oil pan, type s oil pump chain, pump tensioner and baffle, Karcepts A/C PS delete kit, and karcepts shifter box adapter.

And this is the new D series!

Sent to me from Ryan at Autofair honda(k20a.org vender) K24a1(CRV).

Installing the Type-S oil pump, chain, tensioner, baffle, and oil pan.

Removal of CRV unit with balancing shafts. (no bueno for high rpms)
Image


Plugged oil orfice that use to feed the k24 oil pump, if this isn't done you will have no oil pressure and youll break shit. So I coated a bolt in honda-bond and forced it in there, it isn't coming out, and it isnt leaking!
Image


Difference in oil pump drive chains, type s is longer as you can see, it has a larger sprocket on the pump which cause it to spin at a faster ratio than the CRV pump.

Installed

I didn't get a photo of oil pan on cause I forgot. I started reassembling the timing chain and stuff and realized I need to wait since I'll be installing my type s head soon so I'll just have to do it all over again. I'll take more photos of some of my stuff tomorrow.

Re: Ric's Integra k24/k20 swap, JDM front end. Slow progress, but it'll be perfect :

And Ryan, I don't think you'll have much of a choice on staying updated since I'm sure most of my orders from here on out will be from you.

As a matter of fact. Can you pm a shipped price on rdx injectors and a set of tsx pistons? And a price I just the tsx pistons. Thinking of doing it.

i always thought on the k24a1 you don't have to block any orifice:confused:u sure you had to do that?
any engine without the balanceshaft setup you need to. the A2 pump is completley different


Ive never used AEM but Kpro is generally easier to find someone to tune it, From what I can tell, there isnt as many guys that are familiar with it that can tune it.

Guy who had it before me butchered the shock towers, I wish people wouldn't do this type of stuff, now I guess I have to fab up a dome cover(RC style). Atleast then I can dump and not worry about it.

Thank you. In the process of ordering a DIY Engine harness from wireworx. Now I just need an engine harness/ecu schematic and a miracle to build my harness. I'm very able to do it it's just so easy to make a mistake, so I'll take my time and post progress for any other DIY guys/gals out there. It'll have a milspec firewall connector, raychem dr-25, and all new pins. Stay tuned!!
