ka24de-t using a sr20 t25, what do u guys think?

[sil80S13]

alright guys... heres the deal. i am going to be running a ka24de, in my gf's car, and im upgrading myturbo and injectors on my sr20 car. and im going to have a spare turbo and injecs. lying around. i want to turbo her car.. what do u guys think of this:

SS AUTOCHROME t25 manifold (yeah yeah i know but its not that bad)FMU (heard good things about this)sr20det 370cc injectorsDP, EXHAUST, ETC ETC, and GREDDY turbo elbow off my sr20.stock sr20det side mountprobably running 7-10 psi.new waterpump, new head gasket, net exaust gasket. etc, ( a lil rebuild)maybe new timing chain kit far as tuning..maybe a SAFC not sure...will the fmu be ok?

how will a stock ka23de Mafs stand up to boost? will it be ok? will a sr20/sohc mafs work? hoping for 200hp if lucky.

has anyone done this setup? i 've search for it but nothing.thanks guys.

if your running 7-10 lbs of boost you should probably look in to a walbro 255 too, maybe a high flow cat if you plan on going above 8 psi...and anything close to 10 psi is damn near 100% on a stock MAF, Z32 or if ur like me and wanna wait til later....go grab a maxima MAF first

and DEFINATELY an upgraded clutch....

also check ur compression before you go turbo....and if your only looking for 200 you prolly only need to run about 6 psi.... i know someone who ran 217hp and 224 ft/lbs @ 6.5 psi with a Z31 T3, 370s and SAFC tuned (stock clutch was absolutely DYING too! smelled to high heaven )

[sil80S13]

yeah i forgot about the fuel pump, a maxima mafs? off of what year/? i guess 10 psi is kinda pushing it. maybe just 7 psi. im definetly am going to use a manual boost controller... just wanna stay the cheap road.

I'm liking the idea. I've been wondering about SS autochrome too... I see a lot of their ads on ebay. How bad are they really? Are the turbo's themselves junk?

KA MAF is good til 240-250whp and 370cc injectors max out around there too.The limiting factor will probably be that turbo. Its gonna be pushing lots of heat near redline at 10psi (especially with a side mount IC).

Totally agree.

Also, I wouldnt risk running 10lbs on a SMIC.

[sil80S13]

i agreee with no more than 10 psi on a smic.. u guys think a t25 we be ok on a 2.4L ?

[candela]

I cant remember the guys name, but he had an almsot identical settup and was putting down 300whp @15psi (dropping to 11).

Search on here and zilvia, i cant remember his name but the settup was the same and everyone was amazed!

[hannibal]

AceInHole was his name. He's on FA a lot. He posted a dyno chart where he made 270-280whp with peak boost of 13-14psi. I just read to day (dont remember where) that he switched to a Mitsu turbo (TD05?) from a Volvo.

I think he was a special case. I still dont understand how he made such good numbers with that turbo.

I'm going to be running a SR t25 setup soon and my friend has his running on that with the ss autochrome manifold, just using the stock SR turbo elbow and downpipe

but I'm going to be using a megan SR DP.

it spools REALLY fast, its like instant boost from what he says, I know he has boost in reverse heh.

I will only be running 7psi for about a year, or at least a month or two, then bump it up to 8 if I feel safe and I will be using the S14 SR SMIC too.(it has a thicker core than the s13 SMIC from what I've heard)

but If I go above that i'm going to be doing a complete rebuild (almost) and use some FMIC setup

LOL, thats funny!

pj's a cool guy...i was at the dyno with him when he put 230 something down on 3 cylinders!

i know he did what i'm doing with my motor build....he ran an s13 exhaust cam on the intake valves, but i'm not sure how much that helped his numbers...

[SLde_Show_Enthusiast]

thats nice, i'm going with the same setup as urs... im going to be using an sr t25 because i'm gettiing it for 100 bucks, free 370 injectors, and smic/piping, stock sr bov, tougue factory downpipe, safc, all for $350!! and i'm going to use the ssa manifold with dumppipe for 200 shipped... o yea, still have to get walbro 255lph and z32tt ff too....:-D, hoping to start off with 210whp, then upgrading after i get bit by the boost bug...

[hysteria]

boost in reverse...

[foCk]

ka dieselness...

[Mustangs_Suck]

This is pretty much the set-up I currently have on my car.

-xspower t25 bottom mount manifold-sr20det t25 turbo -cheapturbo lines oil line kit-sr 370cc injectors -safc-sr20det fuel pump-defi style oil pressure/airfuel ratio/boost gauges-fmic with custom piping-blitz bov-jwt pop charger-ngk plugs-ngk plug wires-3inch divorced turbo elbow, downpipe, testpipe -gt spec catback-JDM get coilovers-ACT 6-puck clutch-red illumination gauges-battery relocated trunk-gp sports urethane transmission mounts

There's my list of mods.

I still haven't gotten to experience the power yet, as I'm having some bad tuning issues. I go in on tuesday to get it wideband tuned, and some dyno runs I believe So hopefully I'll be able to put up some numbers for a good range you can expect with yours in the next few days.

I'm running 7psi btw - as I don't have a boost controller yet, just the stock SR boost.

I *might* be having it chipped for this set up too at the tuning shop - so that might get thrown into the mod list..but other than that - pretty much identical set ups - except i have a gigatic FMIC...not SMIC.

oh and btw - from the little i've driven it - yes the turbo spools up VERY fast, almost no turbo lag. it still whips my head back in 4th gear once the turbo spools..which is about 2K i believe. Can't wait to feel it all when it's running at it's optimum performance.

[s13sr20chris]

sr t25 on a kai would limit boost on smic to 7psi(stock boost=no boost controller yay)10psi with fmicthose things are not efficient at high boost and 400cc just makes it worse.

[Mustangs_Suck]

Alright..I just got back from the dyno shop...no dyno sheet to show as everything's still up by them - they are working on some other things I needed to be fixed on my car.

I posted my current set up a few posts up. Unfortunatley, my ECU isn't an EPROM, so they couldn't do anything to it.

It made 200rwhp and 205rwtq at 7psi. It still wasn't tuned perfectly, but those were the best numbers, as after that, the car started getting hot...so the numbers were going in the 180-190 range.

He'll be working on the tuning (something's still burning oil) and rigging up the fan, so it works..and he'll be running it again tomorrow...so hopefully the numbers will stay around the same or get a little higher.

[JRL]

It made 200rwhp and 205rwtq at 7psi.

Thats really not so bad for 7psi on a T25. You could hit 220-230 whp with your set up easily.

nope, i think the #'s are pretty decent for how much of a basic/budget set up this is. If I had a ECU chip set, and a boost controller, it'd be doing much better.

There's still some oil burnage and it runs hot, so I'm assuming if I got those fixed, I'd be able to squeeze out a few more hp/tq numbers...find out tomorrow.

[sil80S13]

good looking numbers, i sugesst a fmic ...the 2.4 would boost up a t25 instantly!... youre right. all that pressure. you'll have instant low end. awesome deal. u cant beat it, sr20det t25 are easy to find. and with that..with the ssa manifold u can use a sr20 dp, turbo elbow etc. it'll make more power at stock boost than a sr20det LOL ..damn nissan, they shouldve made the KA turbo in the first place. what do u guy reconmeed to replace when turboing a KA, head gasket, water pump etc etc etc. thanks guys for your help.

[JRL]

He's already running a front mount.

Id still like to see what kind of numbers you could put out at 11lbs.

if you're talking to me - I have a GIGANTIC FMIC.

As for what to replace - I'd replace all rubber gaskets/seals that deal with the motor, they may hold up, but *shrug* better safe than having oil leakage and having to do it all later. turbo = more heat, heat = expansion. Valve seals are common to go bad when turboing - so I'd def. replace that.
