I figured I would share my 98 Civic Hx coupe. I bought it about 3 years ago from a friend for $1000 bone stock. I knew right away that I wanted to modify it. It started out with a CAI and axle back exhaust. After doing some research I decided that the D16Y5 was not a motor that I wanted to work with but what to swap in. My answer came when I found a 99 B18B1 nearly complete swap at my uncles shop for $800. After about 6 months of parts gathering the D16 was pulled and the B18 was swapped in with working AC, PS and fully OBD2 compatible. A few months later a 4-2-1 header, 2.5 inch exhaust and Hondata S100 went on the car with a result of 133whp and 127lbft. After a while I started thinking about making more power and the decision to go Vtec was made. I sourced a B16 head had it rebuilt and 3 angle valve job done. After the head swap it was back to the dyno for a retune resulting in 161whp and 125lbft. This is where the car is at now. No for some pics

Very nice, good progress.

 

looks like your on the right track and done your research. id recommend ARP head studs and a s300 for tuning the boosted motor. Goodluck! looks good

 

I like the sleeper look. But, for the love of god re size those pic's. Those things are huge. lol

 

nice man, where are you located?
I'm in north phx

 

i agree you could seriously hustle some people like that haha nice

 

i like that. your car look good...lol you're lucky you have a si. i have a 97 civic DX 2d coupe. i still have to work on the front body (just need to repair body thats it) and i am thinking about getting a jobs. so i can save money up to 5,000 or 6,500 bucks so i can work on my car all way. hehe

 

Thanks been building cars for a while now but this is my first real Honda project. The built block will get ARP head studs stock block is running GSR head bolts. The S300 was out of my budget but would have been nice for the data logging and multi boost maps but oh well, may be when it ends up becomes a track car.

 

Mesa. And no I am not on AZHT any more. Those guys are total morons for the most part.

 

Yeah I have no plans soon to fix the paint and body keepin it sleeper.

Thanks
Not an Si its a 98 Hx but I have semi converted it to a Si with DOHC Vtec and rear disc brakes. Wanted to hint at what could be under the hood but did not DOHC Vtec all over the car either.

 

nice progress, but lose the si badge. that is lame.

 

^I have to agree. If it's not an Si, it's not an Si.

HOWEVER, the rest of the car looks awesome. Thank you for knowing what you're doing. Most jobs like this are criss-crossed with loose wires melting all over the place, but your bay looks very clean. Great work!

 

^ Yeah I dont see how people can mess up wiring that bad. It is pretty simple. I used a 98 Dx harness when I did my swap and it all plugged right in except a few plugs that needed to be changed. I get the clean engine bay comment a lot, thank you my goal was to keep it looking like a the motor can in it stock. And I like my Si badge, it is a mini Si clone with a larger block. Still need the Si seats and cluster though. I had thought about putting a Hx badge back on it to mess with people.

 

This says it all.

Let us know how she goes after the turbo!

 

^ will keep the thread updated as the turbo kit comes together. It will be a slow build. I added my Auto Meter fuel pressure gauge to my AEM fuel rail today. Yeah! And ordered my waste gate.
