- This 1100KG 900HP SR20 powered Nissan S15 Silvia was easy to pick from the crowd as one of the standouts at the latest World Time Attack Challenge as not just being good from afar, but even more exceptional upon closer inspection.
Owner and builder Charles Warland took some time out on race day to chat to us about the Dream Projects S15 Silvia build including some of the reasoning behind it’s 2.2L SR20VE power plant over other options like the RB which Charles is also familiar with via his RB260Z build. Sitting 51mm back from its original location as per the Open Class rules, the SR20 runs the Nissan P12 Primera head and a billet block to produce 900HP from 34 PSI of boost via a BorgWarner EFR 9174. PMC Race Engines have been on board with this great package, and internally CP-Carrillo pistons, a Kelford Cam and Nitto 2.2L stroker kit handle the beating flawlessly which is an impressive feat for a new build and testament to the quality of the build.
Charles also discusses why the GT Auto Garage prepped S15 uses a smaller turbo that what it could handle, and how Time Attack design legion Barry Lock (Of MCA Hammerhead and Mighty Mouse CRX fame) planned the build with Charles along every step of the way to make sure things were done right and done once in regards to chassis and aero setup. Driving the car to 3rd place in the Open Class with a time of 1:29.174 was FWD lap record holder Rob “Mighty Mouse” Nguyen who will be looking to crack that 1:28 mark in the RWD next time around we’re sure.
At just under 1100KG with 1000KG of downforce at 180kph the SR20 setup is certainly pulling its weight to keep momentum. With that said, a focus on the overall balance of the car and not just outright power it is well capable of the task and the change in rear suspension from a multi-link setup to a double-wishbone one helps ensure traction is maintained where required via the Hollinger RD6 sequential gearbox. A good range of sensors have been fitted for data logging purposes and with the help of the MoTeC M150, PDM30, and C127 dash help dial the car in to achieve faster and faster lap times.

Got to love that dash mouse!!😂
Cleanest race build I've seen (outside factory teams) for a while.
Rob Nguyen's touch? hahaha loved that as well
haha yes that's a great feature. He held on well too :D - Taz.
To me that's a show car. 😍
Wow, that was a well built car, some serious dollars spent there.
I'd hate to count the hours, but they have certainly paid off too - Taz.
I must have watched the on board about 50 times, what a engine note
Delivering as always. Awesome shots of the car spaced out over the conversation. Thanks for highlighting who some of these famous builders are around the world even though the rest of the world may not know them. They’re legends in their own places, so cool too know more and thanks for clarifying on those.
Can't go wrong with an SR20
The flying lap....icing on the cake as always mate. Awesome work.
And there was B-roll. Tons of it.
Amazing build man! When I hit the EuroMillions jackpot I know who's building my Time Attack Reliant Robin
That boy was pushing it on that lap! Nice build, that gearbox package is damn near instant 🙂
That's really well-built car. Is has tuned in to one of my favourite new channels
She's a work of art eh. I think it's the only video we've ever done that I thought I could get away with sneaking 'Dreamboat' in the title of haha
Stoked we're on your favourite list too! We've still got a ton of videos in the wings from WTAC, SEMA and PRI as well as getting the @racecrafthq channel up and running so there should be no shortage of weekly content for you and we appreciate the comment =) - Taz.
Awesome build and the dash rat is the perfect accessory. 👌
Great video, thanks.
Wow that's really an amazing build!
Brilliant interview and a lovely car ..
Such a detailed review, love it. Hell of a car!
Oh my god the little mouse on the dash hahahah I love it
It looks flawless!
Damn I wanted to see the double wishbone suspension but either way great video!!!
I love it when teams are willing to talk about the technical stuff of their cars, since it's very unlikely that someone else will be able to replicate it.
I mean there is a lot of little things that go into building the engine and a good setup that is not visible by the naked eye, like internal clearances, fuel delivery, compression ratio, cooling system and more importantly the map tune that makes it all work together.
Guys need to stop sweating it and just be more open to share some of the knowledge.
Beautiful car. Great interview.
Cheers Brian, glad you enjoyed it =) - Taz.
Cool! I especially like the four-banger decision.
@GordoWG1 WG1
Agreed! A 300-400hp S15 is fairly nippy, he has eliminated the reliability issue without adding 2 more cylinders so i imagine its fairly quick even at 900hp/1100kg
Slick build 👌
The rear end looks very well mannered in the flying lap. He's hanging onto the rest of it though! Awesome car.
I would love to see the rear suspension they were talking about. Any pictures available?
I think Andre fkn knows!............ You know?
Awesome to see that they’re running an electric water pump because my first question was if you’re gonna be running the VET head usually most guys run them up to 10,000 RPMs and at that engine speed typically you have to go with either an electric water pump or an under drive pulley in this case an electric water pump is if I’m not mistaken used in the bottom left below the blow off valve from what I can see Id just like to know what kind of set up he used for it because I’m trying to think of A similar solution for my SR which will be running around 9k rpm if I can. The camshafts rockers and almost all the rest of the Valvetrain are to be cryo treated since I opted for the det head.
You know :P
Man, do I need to buy one of these
Yeah the Dream Projects name is very appropriate eh! Solid build - Taz.
The s15 is a pretty car in stock form.
SR20VET is high power engine
sick car! that poor little mouse on the dash is like "holy shit!"
after 652 times of "you know" i've lost my count
So you don't know? 😜 Everyone has a bit of a tick that often become a lot more noticeable on camera. Mine is starting just about every sentence with 'yeah'. Just can't help it 😂 - Taz.
You know 😅
Every time he says "builder" I hear "Buddha" XD
I'm more interested in the cost of building cars, and how to get into racing as cheap as possible.
It would be great to talk about the cost effectiveness of mods in different areas of the car, and which would be the best for someone that has no prior experience and minimum budget like 1000 dollars. It's still very educational to talk about these high end builds, but the majority of us can benefit more from entry level-focused videos, but done in a knowledgable and professional fashion such as this one.
And again, another smashing job on the video, hopefully I can see more videos on entry level motorsports soon!
I've always wondered why there isn't a good channel out there putting out content exactly like you're talking about. I will say you're goina need more than a grand, but you can probably get into entry level for under 10. If suggest go to your closest racetrack and walk around and talk to people and see what they say. I'm in the same place as you, love this stuff, no experience tho.
What’s the big Alu box on the passenger side? Beautiful car
PMC Race Engine...............nuff said
great build, could see the car needed some rear tuning, lots of turn in and power oversteer...more rear downforce
The prices of sr20 i should have gotten one years ago. I do have k24 laying around 😂
Yes everything is getting a bit rarer. K24 will go that way too if it isn't already. Fun to try and guess what fun cars will replace what was popular. Different landscape now though with the rise of SUVs kill off a few previous options - Taz.
"you know" 😄
I got nitto 2.2 and full rebuild with gtx2868r but 230kw@w because i asked for a street tune 0,0
turbo too smoll
Why i count how many he said "you know" 😂lol
'Drink, drink, drink, drink!' 😂
Everyone has a tick like this, they often just never know until they see themselves on camera or hear a recording of a conversation etc 😎 - Taz.
Amazing setup, no corners cut. However... 4:33 another turbo pushed about to its limit, another car that would thrive on pre-turbo water/methanol injection
Why would it be better to inject fuel before the compressor?
No it's got no need at all timing numbers are crazy . Egt is not pushed . It makes more than the turbo is rated to . Just needs more turbo
@@fokjohnpainkiller because it shifts the compressor map to the right, which is what they need
@@26Petermc sounds like you've got inside knowledge of the car, awesome. I'm not surprised to hear it's not knock limited, they didn't discuss fuel in the video that I remember but the fact that they've got two sets of injectors per cylinder tells me it's alcohol. However, he admitted they would benefit from a few percent more out of the turbo, might as well spray into that inlet and push the compressor map right a bit. It would only help, not hurt
@@MR__JUSTIN I built the motor . It's e85 . Inlet temps were in the 40s the efr is just to small. No point floging a dead horse. Not seen much if any improvement when it's not needing more timing
What are the advantages of moving the engine back??
Weight distribution and COG so I'm sure it's lower too - Taz
u kno
You know
Look at this. Would you look at that. Just look at it.
1000kg downforce
Tf lol
uno
Tell me if he's selling
"You can't afford this buddy" been a while, I think that's how it goes. Lol
@@matthewmcclain1316 "more than you can afford pal" ;)
Couple of sr20s would pull a premium at race wars
wait wait wait wait - it's an automatic?!
God damn rich Americans
It's manually shifted and the guy is from Australia. Maybe watch the video again :) - Ben
@@hpa101 I thought Chris was the driver, not the owner, as he didn't seem confident about the turbo used. I feel bad, since he's a carpenter/builder. Good for him for building such a great car. That couldn't have been easy.
None the less, a drive-by-wire sequential with auto rev-matching isn't a manual. An incredible gearbox, but with auto-revmatching, that's just too much :P
@@cannaroe1213 ahhh got you. You're one of those guys. :p
Personally I reckon synchromesh is cheating. ;) I joke.
Basically at this level, this is the required technology to be competitive. That is why we LOVE WTAC.
I guess people have to draw their own line of what is "too much".
There is plenty of racing that doesn't allow this type of tech. Check out historic racing, might be more up your alley. ;)
- Ben
Real men use model T gear selection.
"synchromesh is cheating" - haha, oof, I can't really argue against that! You got a point! :)
1/4mile time? It has to be a low 9 second car!
8's with a good driver based on the power/weight, but it doesn't matter. That's not what the car was built for.
M3ntal crazy! Pretty soon we’re going to have 6 second time attack cars
@@pawg206 No we won't. Going from high 8's to high 6's is way harder than you're giving credit. Power/weight is one argument, but the chassis setup is entirely different as well.
@@SlightlyM3ntal yeah dude. Going from an 8 second car to a 6 second car is a whole different game. Those cars are strictly built to go straight.
its not fare to call that engine sr20 lol
Yes it's far from OEM but still more SR20 than anything else - Taz.
These time attack lads are joke, it’s taken them 15 years and another 400bhp to go as quick as a race lap 500bhp spec single seater. I mean that’s 15 years of tyre, electronics, aero and chassis development and they still can’t get the lap times - the early 90’s TS-010 was about 10 seconds faster and that’s 1992. It just illustrates the massive gulf between the aftermarket and performance industries versus actual educated motorsports professionals. People need to learn that bolting shit to car and throwing boost at it doesn’t make laptimes. Maybe a video with some actual proven motorsports chassis engineers could be a good eye opener.
These Time Attack cars do not run racing slicks and must keep some aspects of a production car, given those aspects are relaxed compared to some other classes. They're hardly comparable to a big budget (even that one from 15 years ago would have 5 times the money pumped into it as this car has at least) purpose built single seater with a driver that has many hours seat time in that specific chassis, in my opinion, but you're of course welcome to your own 😎
If Time Attack starts allowing single seaters and slicks at least and they can let rip for lap after lap, which I doubt, then it will be more 'apples to apples' - Taz.
High Performance Academy. Granted but it’s not really the point I was trying to make, laptimes should be derived from solid mathematical fundamentals and a higher understanding of vehicle dynamics rather that bolting on the best of what the aftermarket can churn out and upping the output. All things being equal time attack cars do what they do well but it would be nice to see how effective a more academic approach could be. As an aside - Spec single seaters, no mater what the level aren’t really about big budgets and development costs, just cost effective speed. If, as a race car chassis constructor you’re only competitor is yourself then it’s not in the business’s best interest to make it as fast as possible rather cheap, reliable and robust.
I think you should watch a few more videos of some of the builds on our channel, including the interview with Andrew Brilliant. There is certainly a bit more to it, assuming that you don't in-fact run a road turned Time Attack car that is performing to the single seater level you expect that is. Bit tongue in cheek that remark and I don't mean to insult, but it is one thing to look at something and state how easy it should be, and it is another to actually go out and do it in the real world.
The lap time these cars are chasing around Sydney Motorsport Park are still impressive when compared to the touring car class cars, which are big money albeit more regulated, but also not single seaters.
Essentially, we're going to have to agree to strongly disagree with each-other here haha, but that's OK =) - Taz.
You know
