New 2012 project car 1993 EH6 del Sol Si, budget track whore all motor car...
I just picked up my second del Sol. The color is Milano Red. It is 100% bone stock except for some silly 16" ADR wheels. I'm going to use it as a demo car to show case a budget oriented track ***** setup... It has the D16Z6 SOHC VTEC drive train. I kind of missing having a full interior car, complete with AC and Cruise Control.
Keep watching this log as we install and tune each part. I've decided to name this Project Cheap Dirty SOHC. Since we are on a tight budget, we will be choosing parts that are good quality but as cheap as possible so people can duplicate this car if they wish.

New member of the family! Meet "Cheap Dirty SOHC". AKMEE's new budget all motor SOHC VTEC track ***** project... thanks to Dan @ RCREW for the hook up!

I'm debating if I should pick up a used Milano Red front bumper or just leave it like this...

del Sol seats with blue accents goes well with red exterior.

16" ADR wheels are probably pretty heavy and will also be soon.

Stock ride high is pretty tall and spring rate is way too soft.

Few dings and scratches but overall, pretty good condition for a car that is 18 years old.



Interior is pretty clean overall. Driver's side seat belt's retraction spring is very weak and it is annoying...

I'm not sure if this is original miles on the odometer!

Stock 22 mm front sway bar.

Stock Si does not have a rear sway bar, notice the large stock muffler it is heavy. A 2.5" catback will be among the first modification to the car.

Okay, maybe I should ask the audience on which suspension you guys like to see Cheap SOHC test?? Here are some of the suspension I'm considering:
- ~$650 new Function & Form (full coil overs from Asia)
- ~$600 new Progress Suspension (need to use stock upper mounts, made in USA?)
- ~1050 new Ground Control's OTS Koni yellow + Eibach Springs + extended top hat setup, not exactly cheap but resonable
- I found some Koni OTS yellows that needs to be rebuild for ~$250. I could send it to Lee @ Koni to get re-valved, then get GC coilover hardware + springs kinda want to test Swift springs, but they're not exactly cheap... all of this will add up to be more than $1000 probably, but it will be fresh SP3 valving... hmm!!
- $600 Blox coilovers I know the manufacturer and this should have pretty good bang/buck ratio.
or maybe i'll just swap the old omnipower suspension (no longer available I think) from my EG2 delly-ohh over (I need to strip that car down and send it to L*CON soon)... let me know which setup you guys would prefer to see, or make an suggest. Maybe there's some hot new setup that I don't know about...

is that an nsx in the first pic? kinda hard to tell but it looks like it from the tailights but either way good luck with your project!
Yes it's an NSX that I'm tuning... see http://ghettoracer.wordpress.com/project-na1c30a/
Order placed on ebay for:
- 350 mm deep dish steering wheel with hub and quick release
- silver (to reflect heat better) colored cold air intake system
- dual bend short shifter
- engine torque damper brace (stock mounts are pretty shot, good chance for me to try out how well these suckers work)
- front upper tower brace (Neuspeed style)
Should all get here within this week. :-) Let the testing begin!!

Slammed USDM DC2 ITR vs. Dirty SOHC. del Sol is at bone stock ride height and yet it is still about 1" lower than the ITR!!
ebay seller messaged me and told me they only have single bends and refunded my $16.45. installed the deep dish steering wheel. it is uber nice especially considering the price. the quick release is pure junk though, the bolts won't go through the 6 holes. it is so filmy i think it's dangerous. gonna toss it in garbage. steering boss and wheel are both excellent.
I'm getting excited about this. Stupid ebay store haven't ship the cold air intake yet. Bastards. Moving the Z.SPEED exhaust and test pipe from delly-O to Cheap SOHC this week.

do you own two houses or are your neighbors nice enough to let you park in their driveway?
paint looks good for how old the car is. my milano red is so faded at this point

i own the entire block mang.
actually the neighbor don't live there so we park there to help them. the 93 is slightly faded but a good detail and a wax would shine it up nicely i think... tons of parts arrived at the shop. i'll take photos later today. full hard race bushings goodies from VelocityShop arrived (thanks Freeman!), ebay ceramic coated 4-2-1 header, ebay cold air intake...

sorry about the lack of updates. last few weeks i was really busy on sourcing the funding and getting paper works finished up for business. by monday i will be officially co-owner of N1 Concepts. :-)
Cheap Dirty SOHC is high on my priority so you will start seeing regular updates here and on!! I plan to take it up to Sacto raceway to do some base line drag racing just like how I used to do it in the old project remix days.

Project Cheap Dirty SOHC Part 2 - 04-6-2012 exhaust and bushings
Uploaded by ghettoracer on Apr 6, 2012
Sorry it took nearly 3 months for this update lol. Time passes fast. I was very busy in February and March because I was busy becoming a partner at N1 Concepts. That's all square away now and we are in the re-organization phase still but things get moving forward and I finally found some time to get back on Dirty SOHC.
My old pal Freeman Lui from VelocityShop actually sent the HardRace goodies back in February and I must apologize lagging on this... I'm as eager as anyone to get these goodies installed so I can enjoy Dirty SOHC to the fullest. I'll do my best to have all the bushings done before April is over so hopefully you will see part 3 soon!!

mid night dyno research. added Z.SPEED 60 mm catback and ebay 4-2-1 header. even with stock cat power increase is HUGE!!

ebay 4-2-1 ceramic coated header. but the coating is so cheap it is flaking after like 1 hour driving. lame. at least it does look stainless under neath and it works well.

i was a bit shocked at the increase across the entire power band...

i like it EXGR, must feel nice to be partner now with N1 Concept, congrads sir, will be looking at this thread...
yesterday, i installed an old intake manifold that i have sitting around for years. it's the one that develop by omniman and dnr when they used to work at junk2 back in 2002 or so. it's a crude design but it works. basically they took a 170 bhp b16a IM and mated to a D16Z6 IM flange. then used silicone hoses to play with the length until it made the most power. there were no 3d design involved at all, simple trial and error. this is why the packaging is so poor. imo the runner is about 1" too long when i study the old project remix dyno graphs so after this baseline dyno i will probably cut this one and make it 1" shorter. :-P
still using the stock d16z6 58-56 mm tb for testing purposes. pulls much harder to redline. was going to sears point to drag it but traffic already started so that'll have to wait until next wed. will try to dyno this week.

went to last weds night drag racing @ Sears Point with 132 whp the best run of the night was:
60' 2.535
330' 6.838
1/8 10.412
mph 68.02
1000 13.525
1/4 16.147
mph 86.08
60' time was 2.5's all night long. sucks. but it was consistent all night i was the bracket winner! went through 5 rounds. i think the car is a little bit heavier than i thought. my guess is around 2200 lbs or so and ~2370 lbs race weight. removing power steering pump and ac system next.

by the way, cluster/mileage is not original, just since you asked about it in the original post.
the only clusters with a 6800 redline are 96-97 S and Si.
The 93-95 S have a 6500 redline, and Si has 7200. Your car would have the 7200 RPM redline cluster stock.

Just curious in engine mods alone what has been your out of pocket costs (or lets say average joe buys all the engine items you have what is the total cost)? Also the 132 to 145 HP on the chart was that done by tuning and how much has tuning has affected the total HP outcome of the 145 number? Thanks
