building my *other* CA

[NeedCAforS13]

I was talkin this over with Estevan (badass local SR guy:)) last night, and here's the conlcusion of parts I'd need for a good rebuild of my spare CA long block...

Tomei procam in/ex and gears (solid type) : $630Tomei solid lifters : $300Tomei timing belt : $130CP 9.0:1 pistons : ~$400stock rods440cc gtr injectors: $100polished balanced crankZ32maf : $100new (stock) bearings : $100rom tune (secret services?)stock manifold...

OK so thats about $1700 worth of parts, now add machine work and electronics/tuning/misc parts, and I'm going to try and keep it under $3k... pretty damn good considering SR guys pay what for stock s14/s15 SR's?;)

But the main question I want to know is: WHAT TURBO should I use?

I'm shooting for a good driveable car here... 300whp MAX. In other words I don't want anything super laggy (or uber expensive for that matter...)

Some of the locak guys thought s15bb turbo was a good idea? I like that idea... anyone else got a good suggestion for a STOCK manifold located turbo?

Can anyone else with CA experiece tell me if this set up will produce a good daily driver. I'm shooting for fun factor and drivability rather than maximum speed/power. Not out to set any records, just want a fun car (albeit slightly more fun that a stock CA:D)

I'd like to put one of these on my ca what you think

[NeedCAforS13]

Thats not a bad idea, but too much custom stuff work for me... I want reliability as a top priority... superchargers are cool, but why not just S/C the KA24 thats already in there if you want to go that route? No need to drop your displacement .6 liter if you're looking for low end power!

Sean

[14.5drift]

Ive heard some pretty cool things about the ca's abilities, plus already boost friendly.

[iliketocrash]

if you're only looking for 300whp max then do you REALLY need all those extra parts? i figure some new bearings gaskets and maybe new pistons and you'd be good to go. or am i wrong in thinking this?

[NeedCAforS13]

because I want to be able to do it day in day out without worry... This will be a bulletproof motor I will rev out and drive hard daily without fear of blowing up stuff...

but yes some of the parts are overkill... i'd say more than likely I won't do solid lifters, unless I really want to rev to 9k...

Skip the Tomei Timing belts and get an OEM one.

300 hp.... FP BigT28 and some tuning. I think Secret Services did 299 to the wheels with an S15 T28 on an SR and did 321 with an HKS GT25R

my main reasoning behind this one, is at 9k rpm's I'll spend the extra $100 making sure nothing slips, breaks, or does anything out of order:)

yep, they did, maybe even more... but I'm pretty sure Jay had cams in his motor? I realize its doable for less, but I'm kind of looking for a one stop shot at it... I don't want to be pulling motors, or heads, or anything to be replacing parts all the time... I want 300 hp. everyday. with no worries about breaking stuff. period.

Sure there's a FA guy (enthalpy) making 500something on a internally stock SR at secret services, but I know he doesn't rev his motor out without fear of breaking stuff... I'm suprised (and I'll bet he is too) that its held out as long as it has!

no worries. THATS what I want... being able to beat on my motor without fear of breaking stuff... a quick response, reliable, fun to play with kind of motor:D

Sean

Funny enough I just ran across this post by Enthalpy on FA: "Ever since I set the national record for stock block SR hp @ 539 HP I have had a feelign that i hurt the motor doing it. surely there was no way the engine could survive wiht no damage." So yeah, I think he did have a bit of fear about breaking stuff

a brand new GT3040???? only 1000$ never had exhaust ran through it!!

[quest]

injector limited at 440, puts u in T28 territory anyway.Nothing wrong with stock CA valvetrain or timing belt, so why $$$pend there. Why rev to 9k?.. pointless, since you're turbo cfm will be long done before. Hint: GNs do brutal damage with a 5700rpm redline. You'll actually be decreasing your reliability stressin' your motor like that.Just plug n' play a combo from the uk or aussie guys. They've been doing the 300hp CA thing for years

I'd save the hi rev recipee for the big turbo / standalone picture _IF_ the boost bug bites ya

[float_6969]

Hmm, think we could get a CA to spool a T66? Ofcourse we can! Can anyone say Garage Paddy? hehehe, I love this motor.

Quote »a brand new GT3040???? [/quote] Not bad for such a bad*ss turbo! You can actually take a good condition stock CA, strap on some decent fuel management and decent blower and you're off to damage and reliably. If I can honestly say how much it cost me in total to get 300+whp I would say about $2k in parts and most of that being the standalone. Sean, a simple T3/T04B stage 1 or 3 or T3/T04E with .48 back housing should help you with your quest. I'm pretty sure that before my girlfriend's new car got smacked, I was going to squeeze 400+whp out of a well used, stock CA (except for the camshafts). With the one that I spent oodles of $$$s building, I'm accepting no less than 500whp keeping in mind that I did not disturb the stock bore nor stroke. People are too quick to count the stock motor's parts out for new ones and not even the new ones are going to guarantee total reliability. I say build a reliable stock motor and when parts start wearing, that's when you start upgrading. BTW, I've revved that stock engine to 8800rpm on a regular basis. And even though the valve train began floating around 8500, it's nice to prove that there are some misconceptions about the CA. I've done all I can do to it except push it 25psi on a stock engine with stock headgasket and it's still going. I've seen on this forum where people were saying that the stock CA H/G can't take more than 15psi. If you stop trying to take T25's and T28's to 20psi, you will stop leaning out your engines and burning the headgasket's fire ring. Turning up the boost will cost you especially in the ranges of 15-30psi. And if you don't fortify your fuel system with some competency, you will "pop goes the weasel" every time.

i missed something along the way... what's a "GN"? i feel like a dumbass asking this.

[NeedCAforS13]

grand national... its an old buick that was turbocharged (and bada$$ )

Sean

[Onizuka]

So whats going to happen with the poor SR T25 i sold you sean? i say make a FP Big28 out of it

I can vouch for this!

Get rid of the stock turbo ASAP.

Ive learned my lesson and I warn others who do this.

[boost_boy]

I'll say this about the "Big t28" turbochargers I keep hearing about. I recently sold my super tricked-out T25 that had been magically turned into a T3, respectfully it is a big T28 as well. Although they have bigger wheels and are a bit more efficient, it's still a piece of crap that awaits your abuse so it can pop it's oil seal. I went through 2 rebuilds and had frankly had enough. And to get max power out of these things, you're going to be nearly maxing them out as well. What happens when you keep maxing a mechanical device out too many times? it eventually gives way! Lag seems to be what everyone wants to avoid; but if that's the case, supercharging should be something to consider. The point I'm trying to make is, if you're going to spend X amount of money on a "Big T28", you will come out better getting a T3/T04B or T04E and having more useable efficient boost. But if you don't want to no more than 250hp, I'd say get a standard T28 and tune it correctly. Just passing this along from experience! I've even toyed with turbochargers that are kinda big for the CA18DET and I have concluded that for street use the entry level T3/T4 hybrids are excellent and for high performance the T3/T04E 60-1 is matched perfectly for both some street and mostly highway and strip duties. If you want to get cute move up to the ballbearing variants such as the GT3037/GT3040 as they are beautiful for readucing some of the lag you will experience with the others.

"I've revved that stock engine to 8800rpm on a regular basis"

oh its 8800 now? i seem to remember it being "8700rpm once" last time. im just messing with ya, id never have the balls to rev mine that high (again..ugh). i puss out about 7500.

slw240sx, i still want that turbo. if ive got money after christmas from christmas, birthday, visits from grandparents and my worthless job i WILL buy it (along with all the other stuff i need, dont worry, im not trying to get ahead of myself here). ill still need that downpipe and midpipe from you, and those 440s if you can get them, if not, im kinda broke so waiting a few months may actually be a good idea.

to help answer this post, as i feel i should since i basically did just jack it, some good tuning from a chipped ecu, or if i were you, i'd probably invest in the greddy emanage since its not too expensive and they got the bugs out. and a s15 t28 and you should be close. i have the upmost faith and confidence in the stock internals of the ca, but if you feel the need to replace them, im not saying you shouldnt. you should have no problem making 300whp, good luck with it.

boost,who did your t28 ? how much did it run ? 0.64 hot side ?(jap ca18det comes with a 0.48 a/r, uk ca18 and SRs have the 0.64 hotside, so use that for your core). I wonder if FP higher price is for thrust bearing mod, which allows 'em to last, because they do, and certainly run impressive numbers.I see AGP and turbochargers offering brand new t28 centers for around $500, u could have em cut your housings. Think a new center would have served u better ?

If building for more power later, I'd go with a custom manifold now. A small T3 has the t28s performance covered. Bolt on a t3/t04b for ~375whp. Go 50trim if u want 400+.On my 2nd motor, I'm going mitsu 16G then 20, simply because brand new they're priced right, proven to last and performance unquestionable. No external wastegate needed either.

Quote »who did your t28 ? how much did it run ? 0.64 hot side ?[/quote] M.I.C. turbo here in miami did my T/frankenstein turbo and it cost around 350ish (can't remember exactly). To make this turbo as interesting as it was, the left the .48 hotside and bored it out to accomodate the bigger wheels. This little turbo was wicked as I use to shoot this puppy past 20psi on regular outtings and rested it at 18psi. On it's last days, I unplugged the wastegate and let it sing. Yes guys, I use to run the car open wastegate and still have yet to toss the stock headgasket. Maybe I have a super CA18DET J/K. But that little hybrid lasted about a month of doing that and it crapped it seals and started screaming like a sick witch getting screwed by a horse:D

[slw240sx]

how does a GT3040 happen to perform on the CA??? i just happen to have a brandspaking new one availible to me .. its goin on a 7mgte supra, but hes worried it wont suit him, so hes looking at somthing else. would it be a good turbo for my motor?

tim , 450cc injectors 50$ plus the small shipping charge , i can pick them up wensday if you want.? for 80$ ill throw in chip for the 450s on stock Maf , with out speed cut

[iliketocrash]

so hows that chip burner been working out for ya?

[boost_boy]

Quote »how does a GT3040 happen to perform on the CA??? [/quote] Would perform nicely! although it is a big horsepower unit and maybe a bit of overkill ofr everyday driving.

[14.5drift]

I still say put a whipple charger on it. Good for 30psi from 500rpm

[NeedCAforS13]

that sounds like a decent idea, but I'm not sure you would do about the exhaust manifold? You can't just use the stock turbo one! I mean, headers for the CA can be found, but they will be fairly small diameter, ie. not suitable for a FI motor... so you would have to go custom exhaust manifold/ headers...

kind of alot of work IMO... I mean there's the brackets, the custom mounting (either on the intake manifold or elsewhere)? The custom piping if you want an intercooler. The custom exhaust...

but if you want to take on the task... a supercharged (KA or CA) motor would be pretty sweet:)

Sean

[14.5drift]

A. I wouldnt use an intercooler( no need ) B. I would mount the beast on the side of motor, so yes need some pipes, C. if you can't find the big headers you still get a little more tq, And D. I forgot what d was, but thas what I got planned for my 240. That or supercharged Rb20det
