Blue Turbo 240sx?

[Wildcat]

I saw one this morning at Heritage Pointe Golf and CC, it had an intercool, a couple gauges and the biggest damn muffler ive ever seen, other than that it looked stock (sleeper ;) ) i thought it might be someone on this board

[dj_honda]

i think i have seen it too......does it have 180sx taillights?
i think it was a fastback too.

[Wildcat]

*intercooler, and it had clear corners adn the tail lights looked a little bit different than normal

[redline_13000]

maybe its "hollywood" ' s

[Wildcat]

ya, the tail lights were wierd.. ive never seen them before like that, they kinda bulged into round circles and the middle portion was the same color of the car, not the regular coninuous brake light, i couldnt tell if they were stock or not, it was a total sleeper

[darknight]

Yeah I know whos car that is. His name is Tom he's had the sr in his car for at least 2.5yrs. Originally had the s13 redtop sr in the car now has put the s13 blacktop engine in and just recentley swaped turbos for the Big28. BTY those taillights are from the 180sx in japan, I sold those to him.

What is the differences between the red top and the black top sr engines?

[Wildcat]

oic, that car is pretty sweet, he must have been golfing this morning. Is he on the board? My buddy used to have a 240, i bet with a turbo his car flys, does he have any times?

red tops are s13, blacktops are s14,15. I believe they gained a few hp in the latter two models.

[XylathaneGTR]

Yah. The S13's commonly had Redtops in them. There were a few Blacktop S13 SR20's floating around tho...not too common.
The S14 Sr20det was ONLY in a blacktop, and it also gained a few horses, the S15 SR20 is again, a Blacktop, with a distinct hump or buldge over the 3rd Cylinder. It;s ouput was pushed to 250, wiuth a better turbo than the previous models.

With the S13, I think the only main differences between Redtop and blacktop is cosmetic, altho i could be wrong. I think blacktop was reserved for 180SX or SillEighty or something? where as redtop was for the S13 Silvia... Prolly wrong tho...


And, btw, Hollywoods car is a Greenish S14.

[darknight]

the CA18 was in the S13 from 89-91
red top was in the PS13 from 91-94
black top was in the RPS13 from 94-98
s14 sr was in the s14 from 94 or 95-98
s15 sr was in the s15 from 99+

As far as I know he isn't. Not to sure what kinda #'s hes making right now but when he had his T3/t4 I think he made something like 240hp not sure if that was at the wheels or what. With this Big T28 I think he should see around 320HP.

Ya I've seen this car. Very nice shade of blue.
I absolutely love those 180SX tails. About how much do they go for?

Was there much difference (internal parts/ external ancillaries) between each of these engines? Just trying to learn more about the SR series engines.

Thanks

[ecstasyracer]

I always see this car at SAIT. Awsome sleeper.

[Seanith]

:drool: heritage pointe ;)
i love 240s i would love to get one in a couple years

[shadowz]

yea tom just put in the black top motor , sweet ride

[Autodream]

when he had the T3/TO4E at 7psi he was pushing 233hp at the wheel. with the new big 28 don't know what he is making yet

The ps13 red top and rps13 black top where pretty well identical engines, but the there was quite a few differences between the s13, s14, and s15 engines. The s13 had a low port design intake manifold, uses a T-25 turbo and if I'm correct 380cc inj. The s14 SR used a high port design intake manifold, used a t-28, and also had variable vavle timing. The s15 engine has the high port manifold, somethin like 440cc inj, uses a BB T-28, has a 6 speed, and also has variable valve timing. I think thats pretty well all the obvious differences.

The S15 engine seems to be a nice starting package if large performance mods are the plans for the future. I'm guessing they are the hardest to come by as well tho.

Actually its quite the opposite. The s15 is the last engine you want to start with if you have big performace mods planned, just for the simple fact that the cost of the engine is almost 2times the amount as a red top or black top sr. The red/black top are the best engine to get if you plan on going for big #'s for the simple fact that you will beable to do it much cheaper than trying to do it using a s15 motor. The 6speed can always be adapted I believe to the earlier sr's, of course you'll need to rear diff from the s15 etc since thats where the speed sensor is on them, where the models before that had the speed sensor on the tranny.

I can see that, especially when most of the differences you stated before are ancillaries for the engine that can be swapped away during the mod process.

You see the SR coming in the Sunny GTI-Rs as well. Is the only diff here the tranny setup?

Hey guys,

the car you guys are talking about is mine. Didn't know my car was worth somebody mentioning since it's basically stock looking. I've had it for about 3 years now, 2.5 years with the SR motor. I like the sleeper look and perfer to spend my cash on performance. Although there are days when I dream of a nice body kit along with matching rims...

I haven't got a chance to dyno with the new motor and turbo setup yet, I've heading down to LA next week and probably picking up bigger injectors before I put it on the dyno and turn up the boost. Currently, I'm running about 10psi and guessing that I'm pushing 250 whp. Once I get the injectors, I'll turn it up to 15psi and hopefully get at least 280-290 whp. There are a few guys in the states with the big28 turbo running around 320-330 @ 21psi with bolt-ons.

I'm not too big into street racing, unless... I see some idiot weaving in and out of traffic trying to show off. Then I'll usually wait for a clearing before I try to initiate something.

Lastly, I big THANKS to Auto Dream in Calgary for doing basically all the work on my car for the past few years. It seems like this swap is becoming increasing popular so I might see a few more SR's running around the city sometime soon.

Tom.

what is a BIGT28 turbo?
is it a turbonetics?garrett?
Weird, I have a few friends with t3/t4 that makes around 400-450rwhp on honda engines and some even up to 600rwhp?

[blktopbig28]

A big28 is a T25 turbo that has both housings bored out to fit larger wheels. It has the quick spool of a T25 with higher flow capabilities. According to Forced Performance in Texas, the BIG28 is effecient until 21 psi and could support around 330rwhp.

The T3/T4 I had produced 233 whp @ only 7 psi. I didn't push it past 7 psi because my injector duty cycle was already maxing out. With a properly tuned T3/T4 setup @ 20 psi the SR can reach the 400 whp with stock internals. This is quite a popular setup for the guys in the states. The turbo is relatively cheap with good power potential.

I really liked my T3/T4 setup, but I missed the instanteous response of the smaller turbo, that's why I switched. Where the T3/T4 really shines is once it passes the 4500 rpm mark, it pulls HARD. Below 3500, it's pretty weak.

The Big28 gets full boost by 3100rpm, tons of low end torque and extremely broad power band. Check out the first link for dyno chart.

Hey tom, how do you like that SPEC clutch? Don't you have the stage 3 one?

[DSM Power]

Very nice. What size of injectors are you running now that you need to upgrade?

CA18:thumbsup: :thumbsup: one of the two engine options for the S12 in canada. Good motor:love:

[blktopbig28]

Orrin,

I LOVE the Spec 3 clutch. Takes a while to get use to because it engages so quickly and abruptly. Definitely takes some touch to drive it around the streets. Pedal is slighter stiffer than stock and capable of holding 450+ lbs torque. Of course I'm no where near that level.

How are things gonna with your redtop? did you get a new head/block since we last talked? Later.

Tom

[blktopbig28]

DSM Power,

I'm currently running 370cc injectors and will be upgrading to 740cc. I'm maxing out at 10 psi (I tuned it on the rich side to avoid denotation) and figured the 740 will enable be to run higher boost without taxing the injectors too much. I'm chicken sh!t when it comes to pushing my motor... better safe than sorry (and heartbroken for the matter).

Tom.
