People with precision SC-61's

[Jezz_s13]

firstly are any people running them?

If so what kind of revs are you seeing good boost at?oh & what spec is it?

I'm thinking of going for...

SC61 with...76 Exh Trim.63 A/RT4 hot housing (probably)T04S Compressor housing

Linky...http://64.49.247.187/index.asp...D=101

Is anyone running a config similar to this on a CA18DET?

Is there likely to be any difference with respect to lag (or in any other respect) between the T3 and T4 housings other than cosmetic?

Does anyone have any links (RR graphs etc) to CA's or similar sized engine (SR perhaps) running these turbos?

Basically I'm lookng for a turbo that can deliver 450rwbhp with relative ease, and 500rwbhp if pushed a bit. Is this the turbo for me?

I've found some details (RR graph) of one of these running on a 1.6l civic giving very good boost by 4.8k and delivering 500+ bhp, this I can live with on a CA as it'd probably drop to ~4.4 with the bigger displacement.

Sorry for all the questions but I need re-assuring before I take the plunge LOL. :D

Cheers,Jezz.

i dont think anyone on here is running that turbo (atleast not anyone who posts regularly). Hell, I'd never even heard of it until you mentioned it a few posts back. Sorry I can't help, but good luck! Sounds like a great project!

I'm 99% sure this is the turbo Enjuku used to make 544whp on their SR. Here's their chart:http://www.enjukuracing.com/ken/racecar/544.jpg

[Jezz_s13]

Cheers for the replies guys.

Mmm just been having a poke around on the enjuku site, some cool stuff, gotta say I like their S13.

If that's the turbo they are using it looks possibly a bit big for what I'm after, there is another graph from before that one showing 496rwbhp, the curve looks much more driveable from a lag POV.

http://www.enjukuracing.com/images/dyno.jpg

I don't want to be revving into the the 8k's if I can help it too, I just want to save that for the occasional high speed run, not a daily occurance, I think the CA crank is likely to flex a bit at those kind of revs and start chewing mains.

Do you think the Enjuku guys would answer any questions RE their setup?

[boost_boy]

If you don't mind seeing full boost at or around 6000rpm, I say go for it. If you're a horsepower hunter, then this is what you want! But if you're one that's toggling between street performance and strip adventures, I would honestly say that this one is a wee-bit too much.

[Jezz_s13]

yeah you may well be right Dee LOL, whatever turbo that gave this graph on the SR is probably the one for me... ~550flybhp @ 7.2k is just the job and the curve looks really quite driveable.



The turbo I have at the minute, a smaller T3/4 hybrid gives very good response 1 bar @ 3k, 2 bar @ 3.7kish but is only good for ~400fwbhp.

I once thought 400flybhp would be enough, does it ever end???

[/quote] And the answer is "Hell-No":) I just recently discoverd water in all 4 cylinders in my old lady's car which tells me that the headbolts have been stretched too far. So I got cute this A.M. by getting on the phone and ordering new forged pistons and rings for her CA. My original plans were to leave this thing stock internally and move on to installing my built motor (Not happening)! $561 for pistons and rings, more $$s for head work, new head bolts, rod bearings, etc, etc. So in short, it's a neverending story!

I was told by Ray that the turbo used for this engine was a step DOWN from the SC61...

Actually I think the one for the 549RWHP was a step down... but I'd have to check... Who knows... the SC61 is supposedly to be capable of 680HP when tuned effetively.

[Jezz_s13]

Ah right so it probably was a Precision Turbo then? That's good news if it was.

Yeah the 680 thing I assume is at the fly and with the top spec version of the SC61? Saying that, 544@wheels is at least 600 I'd say.

You car is going to seriously shift KaZ.

Dee, don't you know it. :DPutting forgies into you old dear's car is damn cool though.

Luckily I already have re-shotpeened rods on standby and NISMO 1.2mm metal headgasket to accomodate. I guess I won't be so timid about turning up the boost on here car now;) . On another note, you boys like lag, huh? If tuned properly, you should see big numbers with that blower. And with a bit of nitrous, you should kill with it at the track. But around town and no nitrous, the little boosted Vtec boys and SRs will give you hell out the hole.

Dee

[Jezz_s13]

Mmmm double wallet smacking, you should buy some tuning parts from the UK LOL.

fortunately we don't have any boosted vtecs really here, yet. Certainly no local ones, the only one I know of reasonably local is in bits again after running a miserable 226@fly.

Well, i've gone through the fastish fun car stage, it's rapid as it at the moment really and totally driveable, but I'm bored so I just want to build a relative monster (for the UK anyhow, biggest powered CA is 516@hubs in the UK at the minute).My goal as I may have said before is 200mph so it'll be fun trying to get there, I reckon I need at least 500 to get there though, 550 will do it pretty sure of that, but it will only happen if I can keep the torque up at 8k, mmm. At the same time i want to keep it quite driveable, i could shove a huge turbo on it and be done with it, but as you say, 6k is no good to start moving at.Another thing is I'm doing it all myself, as lots of us do which makes it more of a challenge/learning porcess/hobby. It's cool, and good fun apart from when it goes **** shaped.

When I've done that (or give up after trying) I move on to an R32 GTR and start all over again LOL.

Not going to touch nitrous, I'm not really interested in it.

[Dori Dori]

Not a CA or a Nissan engine but figured you'd enjoy this:http://www.racingsouthwest.com...&st=0

Cliff notes:Built Miata w/ 1.8ltr and PTE SC61 running about 28psi runs 10's at 139mph. Video link too.

[Jezz_s13]

That's seriously cool, and I love the last post!!!

PMSL. Holy crap!!! Miata's aren't gay anymore!!!

[quest]

fullrace.com claim to have 500hp civic 1.6L and 1.8L turbo setups that should do the trick for you... email em

that 10.98s miata mentioned as well in that thread was the purple one featured in sport compact & turbo magazine that blew away the *built* sr20, b18 and 4g63 ...embarassed 'em actually, using a bone stock junkyard 1.8L. http://www.racingmazda.com/mini.htm# My runabout for some time was a '92 ford escort GT with that same 1.8L mazda motor. It is an excellent powerplant! Recipee should work the same on a ca18.

I'd concentrate on a more responsive turbo with more are under the curve, seeing as u spend more time driving/ enjoying your car than bragging about some silly high hp figure - I'd leave that for the tuning guys trying to sell their services and the racers. t350 76 trim (similiar to a stage5 wheel claimed) in a 0.82 t3 hotside housing will give bigger numbers but be a dog on the street.

this guy replaced his sohc 12v 2.2L with a dohc mazda 2.0L in his probe and have been swapping various turbos, because he got a hookup at PTE he told me.http://www.sdsefi.com/features/nov03probe.htm Made 401whp @22psi. Switched out the 60-1 compressor wheel only, and NOW gained 40hp to the wheels - same boost on PT61. He runs a 0.63 t3 buick GN style housing with the BIGger t350 wheel (full boost at 4800). He says the internal wastegate holds boost solid, so u may save money there. I believe he said the PT61 is the buick version of the SC61, same turbo but costs $675.

If u wanna see a TON of different turbos ran with dynos and track times, hit up those dsm guys.... although a 2L, u shouldn't be too far off. Many run 18-22psi street/ 25-28psi race, stock ecus too.http://www.dsmtalk.com/forums/http://ww ... mnabr.com/

[Jezz_s13]

Cheers Quest. Been damn busy in work the last couple of days and my PC at home died yesterday so not had time to have a good look yet, but the brief look i have just had looks like it could be wuite informative cheers. .

[CA18Fastback]

found an SR guy who is going for 600hp with none other than an SC61. look...http://www.zilvia.net/f/showthread.php?t=51656

[Jezz_s13]

Cheers.

Almost makes me want to put an SR into my S13, don't worry though, I wont.

[Projex240]

use the t3 foorprint--it will lend itself to a quicker spool, and sacrifice no power at all. If you want quick powr and good lag time--use a mani witha dsm t25 7cm flange--and call up forced performance. They have the fp3065. This is a 650 whp turbo, and has proven itself many times on teh dsm cars. Its also dual ball bearing and makes over 30 psi reliably if your motor can take it.

_josh

[Jezz_s13]

I went for the SC-52 with T3 hot housing but bigger wheels/trims in the end, after seeing some RR graphs of the 61 it looks a bit too laggy.

I'm going to see how I get on with the 52, if the engine stays in one piece i'll get a big trim GT35R.

[Projex240]

sweet- Ivan st spracing made about 360 something i think using a sc-50 on a ka-ths was with a aem ems.. The sc61 on a ka lags till about 4500 for full boost. on the b18 gsr motor, it lags till about 55--6000 rpms--very laggy. BUt it dependds on the gear you arein, and the motor load--you should be VERY happy with that sc52--good response and sweet power.

[Jezz_s13]

Is that 360RWBPH?

The 50 is quite a way down in sepc of the 52, infact it's probably about the same as the turbo I have at the minute, though mine's a T3 0.48 turbine with 0.60 TB34. It's supposedly good for ~400fly tops, but I'm stuck with the crappy stock manifold at the minute which just doesn't flow more than ~320-330bhp. it makes 322fly @ 1.3bar, i can run it at 2 bar but it'd still make the same power only it'd melt my head for me due to the manifold. LOL

i get superb response from it though, 1.3bar @ 3.2k, 2 bar at ~3.8k, this is one reason why I went for the 52 first I'm spoilt with the lag on my turbo, it's better than the old UKDM SR T28 i was runnig before. i want to get used to lag gradually, like you say the 52 should be a reasonable compromise.

[Projex240]

look at it like this--lag is justa courteous head start--lol

the sc50 made that number on the dyno. Liek i said though. it was with an aem ems. with standalones, they can do wonderful things. About that stock mani--i have been looking around, they have some of those ssautocrap ones on ebay right now for the ca, but i dont --know about them--some have good stuff to say about them, some say they are crap--what other options are there for you anda mani? im asking--cuz ill want one.

[Jezz_s13]

There are a few (quite a few) running ssauto****e mannifolds here in the UK on the SR, and to their credit they don't seem to be too bad.The CA offering though does look piss poor, someone here has one to try, and a friend of mine has just bought one with a VERY open mind.

Personally if I wasn't making my own (with a lot of help from a few friends) I'd get JGS Tools to make me one, not very pretty but it'll do a job.

Another CA manifold option is the Greddy TD05/6 manifold, there have been a few on Ebay for ~ $300-400 recently.

Get this, I'm going to be using std management or at least will try in the name of R&D, I've got yet another friend (http://www.h-dev.co.uk) who has written (with the help of one of his friends) some very cool interfacing software to the stock ECU.If it doens't work I'll go Haltec, but I think it will work.

I'm probably going to make my own intake using a GTi-R plenum, but again I am going to push the stock one as far as possible, I think with a decent sized TB it won't be too bad.

[Projex240]

i agree. The intake manifolds are hard to max out really. And pushing to its limits will surprise many tuners. The turbo manifold though, i have heard many people using them for sr, and they fair pretty well. I ahvent seent hem tear up ALOT, just enough to get attention drawn to them. About the std management, this is VERY cool. Does the ecu have to be socketed to use the software? or can it be done from the harness plug.and on the jgs tools thing, i have used them befoer with a ka motor. The only thing i dont liek is that fatc theya re log,a nd i dont like the way a log style lends itself to higher roms.

-Josh

[Jezz_s13]

basically Jez (my mate, another jezz) plugs his romulator type thing into the ECU after socketing it, then he can look at the fueling and timing map and in real time it highlights the part of the map that is in use. You then drive around a lot mapping in real time, when it's done burn a chip and pop him in the socket.

Jez himself has just done a build with a GT30 and has been slowly increasing the boost and mapping away, he's upto about 360rwbhp at the minute but his fuel pump (bosch) wasn't up to the job.He's just fitted (today) a walbro.He's running 650's and a Z32 MAFS.

Again I am running a Z32 mafs with 560cc's at the minute, and plan to use the MAFS on my new build, if it maxes out I will play with remounting it in a slightly bigger bit of tubing to give another 10-15% meterage.

i accept that some of this stuff might not work, but I'm willing to give it a go, I'm pissed off with tuners saying "you need this for that power blah blah"

[Projex240]

go for it--especially in the name of helping other in the long run. If this gets out that he has rom tuning--then shoot, he and you could make alot of dough. Id be a test mule for a product like that anyday.WHo burns the chips when they need to be changed--and are ca ecus already socketed for ships--they are eprom ready?!

[Jezz_s13]

no you have to socket the ECU, no real biggy though.

I guess this is the catch, I'm not sure he will sell the software.he makes his money selling generic chips and doing custom mapping, to sell it would bugger up his niche.The UK is quite small so it's not such a big deal to go see him and get it remapped.

[Projex240]

ahhh--i see. Too bad im like--oh i dont know--2k miles away--arrrrgh.

lol-j/k

[biosehnsucht]

So Jez built his own romulator?

Interesting, I'd had some ideas for building my own eventually but haven't the time to build the prototype much less write the firmware for it.. I do have all the parts that I *think* I need.. hah

[Jezz_s13]

I think he has an off the shelf romulator, though not 100% sure, but has written his own inferfacing software.
