What to buy with $6000?

[sprfst240]

This 6k is burning a hole in my pocket. Im interested in hearing your guys opinions on a logical set up for my ca18det. Here are the parameters:

1. Easily tunable- i can work with a safc but standalone seems too difficult

2. Looking for a reliable 300+whp that wont stretch the efficiency of the turbo

3.Id like to retain the factory exhaust manifold so i dont have to make drastic changes to my exhaust setup that i was given for free

ok well heres what i allready have:-ca18det -custom welded 3inch exhaust from turbo dump pipe-boost gauge, a/f gauge-s14 radiator

Heres my planned setup so far:-nismo motor mounts-spec clutch-greddy type r bov-xs engineering diy intercooler core with custom piping-walbro fuel pump-S15 turbo or like turbo that retains factory location ect.-apexi power intake-electric fan -550cc injectors-jwt ecu -z32 maf sensorI know that doesnt add up to 6k, thats just a start to things.Any opinions or suggestions are welcome. Thanks blake keirnessammamish, washington

"xs engineering diy intercooler core with custom piping"

if your going for a DIY anyway, may I suggest a GTR core, or do you really want that shiny FMIC?

"greddy type r bov"

I believe that for the max boost that the T28 is going to make, the Type-S is more than sufficient. The T28 maxs at 20=22psi

"jwt ecu"

do you not want to get a standalone becuse it costs too much, or 'cause of the installation? Or do you not think you can tune it?

before you go with a "one size fits all" ECU tune, I suggest looking into EPROM tuning. It is doing EXACTLY what JWT will do, burning you a new ROM, but you can adjust it for your exact needs. AND you can set-up so it can be switchable between a mild street tune (say 7psi for gas mileage) and a higher tune (say 18psi for race)

The actual computer program is free, downloadable from here: http://www.925style.com/editor_direct.html but your burner can either be made by you, or you can buy one.

Xero- First off thanks for the helpful advice.....1. im unfamiliar with the gtr core....what sort of price should i expect to pay for one in decent condition 2. I was strongly recommended the greddy type r by a local shop because in their experiences the greddy type s leaked badly. 3. I am looking for something i can install and tune myself, money is not an issue...and i believe a standalone may be over the top for me. Ive never thought of diving into eprom tuning cause its not suggested as regularly as other choices are. I will deffinetly look into it now that you have brought it to my eyes. As far as standalone systems go would something like a sds be the least complicated and user friendly?Thanks againblake keirnessammamish,washington

there's a member that owns a CA18 and I believe that's his job, he tunes SDS systems.

A good start for EPROM is this site: http://www.boostcruising.com/silvia/eprom.asp

I'd check eBay for GTR cores, I believe you can find them there.

The Type-S will leak under heavy boost, that's also why they're adjustable. if it leaks, then screw the bolt down. I believe the Type-R is used for 30+psi,

[McAdam]

If your looking for a standalone, but not quite, may I suggest a Greddy E-manage. lots and lots of features, but still retains the stock computer. check it out. as afar as an intercooler, just get a Isuzu NPR intercooler. these things are supposed to be bad arse.

uhm, Id stick some money into suspension and drivetrain modifications. like a LSD diff. maybe a lightened flywheel? a set of light rims and some grippy tires, perhaps some coil overs or KYB adjustables?

just a thought

Other than the before mentioned mods i also have:eibach springskyb agx shocks17 lightweight no name rims, i also got for free

McAdam: I am very interested in running a greddy e-manage and profec E-01 boost controller BUT im not confident that i wont have the same problems that others are still havingthanks again for the replyblake keirnessammamish,washington

[slw240sx]

the problemns with Emanage have been solved.....

i will probably be running a emanage along side our chips if i go with a big turbo this winter. im really leaning towards making this car a MK4 supra killer... everyone i know into cars around here all drive big heavy 400hp an up supras. im goin to showem all up...

[Nismo1182]

When I can take out the new Cobras, my mission will be done

I really hate Fords. Ive taken out a few new GT's, not really a challenge anymore.

[CA19DET]

$6000 here's what i'll do

Forged Pistons - $500 (can be found lower)Forged Rods - $700 (can be found lower)Greddy Emanage - $600 (software online FREE & it can be found cheaper)Metal Head Gasket - $200Greddy V-Spec 24 Intercooler Kit - $750RC 550 Injectors - $360Blitz Nur Spec Exhaust - $5003" Down pipe & Test pipe (cat optional) - $210FP BIGT28 turbo - $750Walbro Fuel Pump - $120HKS SS Blow Off - $250Spec Stage 3 clutch Kit ~$300

thats a total of $5095

that is a potent combo to TOTALLY reliable 350WHP, you have an extra $1000 to buy all the odds and ends like turbo timer guages water pump, gaskets etc etc....

*OR you can scrap the Pistons and Rods and get a LSD and some Tomei cams a little more conservative but if you are not chasing those big numbers you can get away with stock internals.

good luck...

I would like to comment on the Greddy type S. My friend has one on his awd talon and the bov sounds really nice but he's owned it less than a year and it leaks like biatch. I don't know if its a spring or a seal or what that causes it, but its pretty much useless now. Adjusting it doesn't do a thing. My friend has also never run more than 15psi on it. I've heard of many other greddy typ s bov's leaking but this is the only one that i've experienced first hand. (or at least close enough to first hand)

[Nathan]

Xero, the JWT ECU is not really a one size fits all tune...it's tailored to your specific application. True, not as much as having them on spot at a dyno to tune it, but it's pretty accurate, reliable as can be, and plug and play. The only drawbacks are it's expensive (talk to Yuri at HeavyThrottle...he can get them for 500) and doesnt get the MOST power out of the engine possible. However, as I allready said...at least it wont detonate or run lean

[sprfst240]

CA19det- Thanks for the helpful advice....You left me somewhat confused, though. So should i build the internals if im looking for no more than 350whp or not? Im unfamiliar with the FP bigt28 being used on nissans.....what sort of advantages does this turbo have over a S15 bb t28 or the like?

Also ive always been curious on where i could find a intercooler kit that would fit my ca18det....if i remember right the sr kits must be modifided to fit.thanks again to everyone for helping out a newb like me

[Xero]

I believe HKS makes a CA18 one, or GReddy does too, or something.

[CA19DET]

I say YES rebuild the engine with forged internals if going over 350WHP, as thats VERY fast for a street car and chances are you'll be revvign and boosting the hell out of the engine. if you are going for this kind of power expect to spend money, but the trick is to only do it once and do it right, no point going for 400whp and a 10 second car that breaks after the first few runs of spirited driving - bah.

remember that these CA18DET japanese engines have very high mileage and parts will be warn, gasket brittle and old, pumps tired, may have seen serious revs and boost even some detonation, slighly bent rods, damaged crank/bearings, tired oil pumps... rings, vlave seals, gaskets may/will need changing.

buy an intercooler kit without the hotpipe, someone on this board is making one i believe or any muffler shop can do it... even better just get the intercooler and make your own piping, save a few hundred bucks..

the Forced Performace BigT28 is a T28 from a S15 or S14 that has been rebuilt with modern components and better flowing compressor and turbine wheels with a slightly ported turbine i think, people ahev gotten DSM's and SR's into the 350WHP and 11 second cars with this turbo, it is a bit better than the standard T28, rebuilt (practically new) with a year warranty and plenty potential, and guess what it bolts right up

what we have all given you here are jsut guuidelines and suggestions, please do lots of research, ask silly sometimes embarassing questions and search some more, remember thats $6000 you are playing with and if you dont buy carefully you can end up spending allot more on parts to finish a under budgeted project or fix a problem because you held back on money...

JWT, at $600 is a fck'n ripoff, for a freakin' chip. Plug and pRayuk and aussie guys are FAR cheaper, and they are more in sync with ca18det/ecu environment... they actually live with these cars everyday. jwt dosen't. I'm pretty sure someone in S. florida does ca ecu. $150?Make sure the greddy emanage users have no more timing issues on the caI've "heard" mabastu? (uk) got a patch to fix it, but never seen a post on the gains from timing adjustments via emanage. I'm not sure u need to adjust timing, for 300+whp. DSMs do it with only a safc + 550s + 16GI'm gonna try a $300 piggyback, does fuel AND ignition. Will post IF it works... does on a coil-on-plug toyota I know of.Folks have claimed 350whp; head gasket, pistons, rods all stock. Perfect for a "hot" T28. Build on any 0.64 hotside. NOT jap 0.48 Old bearings will bite you tho.All this needs to be in a FAQ. Rechewin' the same old sh1t. heheh

[Xero]

for the amount of adjustablity for the money that the e-Manage gives you, you'd be better off paying a pro tuner to tune your ROMs with your car on the dyno, or learn to do it yourself.

EPROM tuning gives you the maximum adjustable rpm points, and it doesn't just to fuel, it does ignition timing also, so no need for a ignition system like a MSD unit or something. It will also allow you to remove the Rev limiter and the speed cut

[slw240sx]

the profit on the chips is BLING BLING.. i would go EManage and custom chip if you dont have a pro tuner in town that can map it for you.

[CA19DET]

i would go with the emanage, the update file cures the CA timing issues, as far as benifits of timing via the e-manage for the CA well that is understood...

Jez Horsham of http://www.horshamdevelopments.com makes VERY good chips for the CA at a very good price, in any stage of tune you want. he is a UK bloke and very knowledgeable and confident in the CA18 ecu.

the thing with the eprom tuning (i was looking into this big time) is that you ahve to be VERY carefull what you are doing and KNWO what you are doing, removing speed cut and rev cut is one thing but getting timing right, injector maps etc can get tricky, the interface is not as simple as other piggyback or plug and play tuning electronics.. go E-Manage for ~350hp and S'afc for ~280-310hp, SDS, haltech, electromotive or others for 400+hp

[Nathan]

Oops, I kinda forgot we were talking about a CA here...I wouldn't use JWT for a CA, I would actually use one of the UK guys (talk to Paul_S13...if he cant do it, he knows someone who can I'm sure). I was thinking of my KAT...in which case Jim Wolf has a TON of experience tuning them

[240SXer]

My greddy type S is leaking. Just a FYI, I believe they suck.

[boost_boy]

For $6000 grand, you can do a lot and still keep $$$s in your pocket. First off, ditch the T2 small series turbocharger. Get a nice T3/T4 hybrid of your choice (preferably a T3/T04E stage III)= $450-$750, get a nice standalone (preferably SDS)=$1300, get a nice set of MSD 72 lb/hr injectors=$360ish, a nice header manifold=$550ish-$1000ish, a nice wastegate (HKS will suffice)= $300 and nice NPR intercooler with custom pipes and with this combination I can push over 400whp out of your stock motor without hurting it. This will leave funds for a rebuild if you need more power. And if you're still afraid of standalones, come see me and I'll install, tune and help you totally understand your investment. But if you want 300+whp, stay away from the T25s and T28s; you don't have an SR20 nor it's displacement. The majority of the stuff mentioned above is tried and proven in real, everyday cars including my own CA18DET powered sentra. I didn't mention the e-manage because it will require a laptop to gain access, no fun! Don't be afraid of standalones because they are man-made and anyone can do base-line tuning if they are looking for the edge.

gt25r?:) any comments on how that would work with our motor... what about an FP Big t28. I'd really like to keep something that fits a stock manifold!
