Single Cam EK

[Cyrbuiltsinglecam]

So I started off with a stock EK (5 speed, HX, so economy version, with the D16y5 eco-vtec motor)

[IMG][/IMG]

The car had 116k miles, all original, just was keyed pretty bad from previous owner but I didn't really care because i knew i wanted a fast car and not a pretty car. The car always ran kind of funny, and i never was sure why. It ran and i was happy with that while I started saving for a B series swap. I got inpatient and just wanted to make it a little cooler, so i bought a turbo kit off CX racing, ebay junk.

So after I installed the kit and got over some electrical issues, I took it out for a test drive on the base map i got from HAMotorsports. The car was running fine besides a slight hesitation when I would initially start to go from a stop. I really only wanted to make ~200HP and I was content. I brought the car home from getting lunch/test driving the same day it was finished. I went to start the car and it would crank but not start. I really had no idea why. It was getting spark and fuel, then I noticed the cam shaft wasn't turning. I assumed I broke the cam since that was my luck. The car ran for about 4 hours. So i decided not to do a B swap and go Vitara pistons/Eagle rods/Stock sleeves. The cam gear actually was just stripped by the way. Previous owner left it a little loose. Oh well too late.

And I also got a fresh D16y8 head and block. My buddy sold me his Holset 50 bucks and after a 50 dollar amazon rebuild it was mint.

So this was the second build

D16y8
Brian Crower Stage 2 cam
Brian Crower springs and retainers
Stock valves
Stock port
AEM cam gear

Block:
D16y8 stock sleeve block
D16z6 Crank (better oiling properties)
D16y8 shimmed oil pump
ARP head studs
Eagle rods
Vitara stock bore pistons
ACL race main and journal bearings

Everything else:
CX Racing intercooler
JHP USA Traction bar
Progress Racing Coilovers
Holset HX35
Stock intake/TB
1000cc Bosch Injectors

So then we took it to the track after it was tuned to 20PSI making 312HP/244WTQ. It ran 11.93 @ 116MPH right off the trailer, full weight. That race was against a nitrous K swapped EK hatch who wanted to race a single cam because they are slow.

And finally, the rebuild. A CNC head is being built, with oversize valves, and full Rocket Motorsports valve train and stage 5 cam. It is going in for a 10 point cage with a window net very soon. It will still be a 1.6 liter single cam, but will be sleeved and hopefully make 700 on a BorgWarner s362. The parts I have so far are...

You can follow me on instagram for more time efficient build update, @cyrbuiltsinglecam

Thanks for reading

[storey618]

that escalated so quickly! lol

[Cyrbuiltsinglecam]

Well i like to convince myself that if something breaks I might as well just upgrade the whole thing lol

[hinrichs]

Really wasnt sure what to expect with this one, very surprised by the outcome. Was a little worried when I first saw the cx/ebay turbo kit lol.

[MommysLittleMonster]

That went from groan-worthy to "fuck yes" in a hurry.

Great build. Go Autoworks makes great stuff.

[Cyrbuiltsinglecam]

Trust me I am kicking myself in the ass for not just doing a balls out build from the start, but it is what it is, I learned my lesson.

[jalenda9]

Sick shit man. I was thinking about boosting my 99 cope but I sold it and bought a s13. But I still have my 93 integra I'm building for boost. It also has a holset but an h1c with a 9cm hotside

[Cyrbuiltsinglecam]

What motor is in the integra? My single cam made 7.9:1 compression and spooled the 12cm housing at around 5k full boost. 4.5k it would be at about 10psi.

[Cyrbuiltsinglecam]

So I figured I would include my next build plans that are already in progress..

1/2 inch head studs
10mm (I think?) main studs

Tranny will probably be a stock GSR possibly with a handcuff

Catch can is a GO-Autoworks 6 port can, 4 from the valve cover/1 from the block/1 plugged

This car will be street driven too

obviously left out some of the BS

[jalenda9]

B18a1. Stock cr. Forged rods and pistons
Std bore
Stock head+arp head studs

Nothing crazy just shooting for like a 300-325whp street sweeper now that I have a 240sx. I just want the power to be usable on the street. so a quick spooling turbo that hopefully won't choke out.
I had the original 18cm housing still but opted for the 9cm. if it doesn't make what I want it to make then I'll probably go 12 cm.

[Cyrbuiltsinglecam]

You should make that power with no issues. 300 HP is fun, and i spun the beginning of 3rd on 225 radials lol.

[Cyrbuiltsinglecam]

Alright so I have some updates, first my buddy gave me a new, already gutted, already slightly cut shell, so that is the new race car. The red car is going to be a daily, currently just a single cam but maybe eventually a b swap. So once i get good photos of the new black ek i will post them up. Equally as clean, just been cut.

Also my fabricator sent me some photos of my intercooler!

Also my machining guy sent me the final price on my block for machining..

Jesus that escalated fast. I thought this was going to be a first car build thread when you were talking about the CX turbo kit and how the car being keyed but it didn't matter because it was a fast stock single cam, you surely proved me wrong and this makes me want to boost my car soooo bad.

[Cyrbuiltsinglecam]

Nah i have had 2 cars before this one, my first was this bagged 328XI

[IMG][/IMG]

My second was a static miata

[IMG][/IMG]

This is my first performance build though

[Cyrbuiltsinglecam]

Tiny Tiny update, title problems on the second shell so i dont know what is going to happen there. And test fit the up pipe on a built b my buddy built.
