Import Tuner Magazine competes in Castrol Top Shop Challenge

[4X100]

Import Tuner is working with G-Dimension in the City of Industry, CA to build a sick 240SX SR20DET engine. They're competing against other tuner magazines to see who can achieve the most horsepower per liter. I'm curious to see what a SR20DET can achieve when pushed to the limits...:bowdown:

very cool....

If someone shows up with a 4g63 done right it'll definately win.

[civilized_drifter]

my friend is working on putting a 4g63 in a 90 hatch.

i wonder how much it will push and what the specs are

[smelly240]

arent 3s motors crazy with big power? i think that top secret and phoenix power had 3s as their most powerful 4cyls

a 6 bolt into a 240 sounds neato

[Jerrys14q]

Do you know the month Import tuner will release the result on it

[jrocslider]

a 3SGTE is a badass motor. thats probably what i would enter into the competition.

[Vision Garage]

well this doesnt sound too appealing. So these cars will be HP queens im guessing with crappy powerbands that you really wont be able to use?

[brndck]

there are a few companies with 800+ hp sr20s. of course, they're rly sr24det, and with giant drag-only turbos. iirc phoenixs power had one with almost 900ps. i have a feeling that the 4g63 will pwn in this competition.

[slider2828]

This is old, been up for like over 6 months. Its the oil shoot out.

[jdm538]

i heard the f20 from the s2000 puts out best power per liter stock...

but i dont think this matters so the end.

[hassanbakar123]

yeah the f20 was the most 4cly n/a power per liter stock under $100,000

[4X100]

I think the contest ends on 11/3/08 but I'm not sure when they'll post the winner. They're pretty good about updating the website with that information so I just follow up on that.

BTW: I must've entered that contest a million times to try & win that motor...HAHA! :jerkit:

Ya man Modified Magazine's shop is building up a sick 4G63.:2f2f:

[Eyemfaster]

I don't think it's just a peak power contest...

The basic rundown for the rules is as follows:
• Production engine from a production based car
• 100-octane spec fuel
• Spec Castrol Syntec synthetic oil of shop’s chosen weight
• Only one forced induction permitted (factory counts as one)
• No methanol, fuel or water injection
• Custom parts are allowed
• No muffler during testing, but header must fit a production chassis



After each engine is finished, the engines will be given a total points score based on peak horsepower and torque per liter of displacement (turbo (http://blogs.sportcompactcarweb.com/6238851/car-events/castrol-syntec-top-shop-challenge/index.html#)/supercharger are given a 2X displacement multiplier), power under the curve, surviving a 30-minute drive cycle and a subjective judging panel for quality and craftsmanship. All testing will be handled on an engine dyno.

[sldbyuramg]

built 4g63 will beat any motor in that comp...(for forced induction) its iron block is brutal

[steve shadows]

Is that a freddy intake manifold? The casting looks horrible. I would hope they at least use a real greddy oil pan. ew




Hope they come tune it here.

We're doing higher outputs than people make on dynojets with the same setups on our DD.

With a GT35R and a dynojet I would be looking for 600 whp at 28 psi with the right cams on high octane.

[Oo_Skyline_oO]

yeah the f20 was the most 4cly n/a power per liter stock under $100,000

actually I beleive the F20 was the highest hp/liter engine ever made at one point

[Oo_Skyline_oO]

does it have to be USDM production car?? if not, I beleive an RB26 at just .3 litres away from 4g63 would own

[steve shadows]

HP at 10000 rpm is not as important as overall torque/rpm at lower rpm imo for useful power.

I can spin a motorcycle engine to 14,000 and get 120 hp, but that doesnt mean it will pull a cars weight properly

[StaticX27]

I think a 13B owns them all... 1.3L that can pump out over 800whp :P

[Eyemfaster]

yeah, i'm kind of surprised nobody went that route.

[240trainee]

I like what SCC is doing....

[bmx22]

a 3SGTE is a badass motor. thats probably what i would enter into the competition.

pikes peak mr2 makes 980 hp with a 3sgte.........miss my mr2 turbo

[Antihero983]

Its Import Tuner. who gives a fuck?

THEY arent building the motor, THEY arent even the ones dyno testing it.

them and Super Street need to fuck off in the worst way.

[dorkidori_s13]

anyone know/remember the specs on the old JUN S14 Lemon??? i believe it was a low 8/high 7 second SR20 powered S14...im pretty sure they bored and stroked it out to a 2.2 litre or 2.4 litre...but i do remember it was putting out huge numbers

[Antihero983]

They should've done a CA22DETT.

[slider2828]

The JUN S14 was fastest at 1/4 mile 8.49 secs... I have the video.... I think it was boosted on a t78 no nitro... It was a bored 2.4 litre.... Sleeved and everything....

[origin_s135]

i don't even read these damn magazines anymore. i got the internet. : )

[steve shadows]

I think a 13B owns them all... 1.3L that can pump out over 800whp :P

Technically by the activity that goes on in the motor it is a 2.6 litre. :bow:

It does the job of 2 cyl in one housing at the same time.

and is completely unreliable haha

If it knocks once, it's done


Jun isnt the fastest if were just talking sr

http://www.youtube.com/watch?v=FV1s-xt0FTg

Mazworx and Hybrid did low 9s on H patterns with 2.0 litre setups

Then Mazworx did 7s in a tube frame car - similar to HKS' silvia

JUN is the fastest Unibody sr powered car, maybe, I'm pretty sure there are faster out there.

Just go browse freshalloy

[wangan_cruiser]

does it have to be USDM production car?? if not, I beleive an RB26 at just .3 litres away from 4g63 would own



LOL are you blind or you dont read? they talking about 4cyl motors

[Pblesh85]

they should have a contest to who could build the cheapest 350whp/350wtq or best bang for your buck for $3000.

Id pay to see that.

[GD-Steve]

Hey everyone this is Stephen from G-Dimension. We didn't want to release info about the competition until we got the ball rolling, but now that everything is in motion we'll give you guys the scoop.

First off the motor pictured is not ours. I don't know where import tuner dug up that pic. As for the rules of the competition, the 4 categories will be:

hp/tq per liter (Basically motor efficiency)
area under the curve (Basically whoever can make the most power)
engine design
30 minute drive cycle

The catch:

Only one power adder is allowed ie. turbo or supercharger. No nitrous, methanal, etc.... Also to level the playing field any motor with FI will have their displacement doubled. So an sr20det will have a displacement of 4 liters.

Fuel will be set at 100 octane only.

Our Build:

For our end of the competition, we decided on an sr20det since its our bread and butter. We tossed the around the idea of running a 13b or an RB26, but to stay competitive with that kind of displacement we'd have to make over 1000hp. Strategically, we don't need to come in 1st place in every category. If we build an all around motor we should have a good shot at winning despite the stiff competition.

As for our motor I can't give too many details just yet(magazine politics), but it will basically be a 2.2L by bore and be capable of high revs (thinking 10-11,000). We are custom building a full stainless steel exhaust manifold as well as intake manifold. Our goal is to make 880 hp at the minimum to give us 200hp/L

Also I want to give shout out to our sponsers.

Wait, why wont the 13b competetive for what you guys are trying to achieve???
1.3L with turbo = 2.6L. If you have a 13B making atleast 600hp, that blows the 200hp/L that youre shooting for with the SR20DET. 600hp on a 13B isnt impossible.

Hell better yet, 20B turbo charged, push the damn thing till its ready to blow...1200hp range will give it 300hp/L...

[chituntang]

There will be rules that limits rotary engines. Most rotary cars compete in racing usually get a x2 in displacement to start. Should be the same for this.

Stop being silly.

yeah our first thoughts when we heard about the competition was 13b, hoping we could get away with it being a 1.3L. Unfortunately we couldn't get away with it, making it a 2.6L. Add the FI multiplier and it becomes a 5.2L, meaning we'd have to make 1040hp for 200hp/L

You have to remember that we are limited to 100 octane. Most cars you see making 800-900-1000hp are running 109, C16, or some type of injection. The octane is really the huge equalizer between FI and NA motors in the competition.
