The Dog II dominates

The VE engine was fortified by a set of Japanese NI camshafts, intake manifold and throttle body from G-Spec. The N1 parts are from the ultra rare SR16VE N1 motor, a race homologation special motor that was produced by Nissan in very limited quantities to race in FIA N1 events. N1 racing is a class that allows only minimal preparation of the car, much like SCCA’s T1 and T2 or NASA’s PT classes. The FIA requires that a certain amount of motors be built and available to the public for parts to qualify as factory stock.

The SR16VE N1 was a potent 1600cc engine rated at 200 crank hp, Nissans answer to the B16A engine used in Honda’s JDM Civic Type R. The engine was found in the Lucero VZR, a coupe that is nearly identical to our 200SX SE-R. Only 500 of these cars were produced for FIA homologation. The N1 cams have over 300 degrees of duration and 12mm of lift. The cams were mated to Jim Wolf Technology adjustable timing gears. . When teamed up with the stock SR20VE valvesprings, they are good to 8000 rpm. The intake manifold features a 70mm throttle body, shorter, bigger runner and a larger plenum.

ASP SR20VE Header
ASP's Mike Kojima signature header is a work of art.

A custom header was built to Mike Kojima's specs from exotic lightweight thin wall 321 stainless using a Burns merged collector, stepped primaries and reverse cone megaphone by Charles Dundon of Advanced Street Performance.The header is one of the key secrets for extracting gobs of power from the SR20 engine. Although the header looks like its all about top end, it actually makes quite a bit of low end torque. The headers megaphone exits into a 3" thinwall 321 stainless Technosquare fabricated exhaust feeding into a Burns Ultralight muffler, exiting to a turndown right under the car.

Burns collectors are the finest, accept no substitutes!

The N1 intake manifold breaths though the 70mm N1 throttle body fed with an aluminum cold air intake built by Technosquare and a large Cobra Mass Airflow Meter. A JWT POP Charger cleans the air at the end of the intake. Technosquare also fabricated the self-draining oil breather system for the engines bottom end.

The Breather tank has separator baffles to get the oil out of the blowby gasses. The oil then drains directly back into the sump. This has cut oil consumption to practically nothing. Hose Techniques couplers and T-Bolt clamps hold the intake together.

the oil separator, return, and crank vent is ingenious.

Mike that header is beyond a work of art, what a beautiful piece! I want one! :)
Lol "Hideous B16" could not have said it better myself!

Beautiful work, one of the best-thought-out racecars that I've ever seen! Thanks for sharing!

Was an edited version of this article printed in SCC once or is it a totally different article?

Mike what's your opinion of this:

I agree and I think its not ideal so I use a rod end with rating high enough for a safety factor of about 4x the calculated max load.

Is it typical that you write these detailed articles and the editors condnese them down so much?

Once SCC started to suck and they reduced page count, yes.

Just like Big J, I too find myself loving the well-thought-out oil separator. I've been tossing ideas back an forth in my head as to what I'm going to do about mine, and custom can + large hoses + self draining were all on my list. Great job!


As for the Nismo wheel studs. I ask you to read through this and consider other options if deemed necessary. Andreas Miko and I go back and forth about the Nismo studs' strength and failure rate. Post #34 also has a link to the Fresh Alloy forums where many members there report problems with them.

Wow you sheared 20 studs! We have them on 3 of our cars and have never had any trouble although I did break one stock stud once on my SSB SE-R way back in the day.

It was the most ridiculous thing I'd ever experienced. Every couple of months, like clockwork, I'd sheer one. This went on for years even on the rear when I had no spacers. I never sheered a stock stud under the same exact conditions.

There's no way I'd trust my lap times, let alone my life, to Nismo wheel studs.

Mike is this the Dog car that you, Steve (in his 350), and me (in my S13) were smoking the shit out of everybody in that one day at Streets of Willow?

No this is the Dog II, a car 100% built by me with the heavy fab being done by the Bros at Technosquare and the cosmetic stuff being done by Kono.

The original Dog Car is pretty fast and well developed by me but it has many issues like a screwed up and heavy cage and improper structural gutting that messes it up that were done by the previous owners.

At industry day the Dog II lapped big Willow at about 1.3-1.5 seconds a lap faster and I am rusty and not driving well. This is without me adjusting anything and no dial in.

There is an easy couple of seconds left in the car.

Mike, can you tell us what specific capacity/model Setrab cooler was used? If not, rule of thumb for sizing an oil cooler with VE? I feel like taking a VE out on the track even with a Koyo isn't enough even for HPDE's, it's just asking for trouble w/o an oil cooler, or at least asking to have to dial it back and pit to allow the car to cool.

Thanks in advance!

I think its a 13 row 119 or 121 I forget exactly, I think the heat rejecting capacity is 20k btu.

My scientific method for calculating what capacity cooler I needed was.... The biggest thing that could package easily! On all but the hottest days the oil temp stays below 230 degrees.

sorry to nitpick, but the EK9 Civic Type R used a B16B engine, not a B16A :) the B16B is more similar to the Integra Type R's B18C engine, I think it is in fact a B18C with shorter stroke.
