Since im away from my car and my life in FL, relaxing up here on Lake Norman in NC... ive been doing ALOT of wondering and thinking and pondering.

My original plan for my CA was going to be a GT30R Bottom Mounted and tune for around 400-425whp... But ive been thinking more and more and wondering if a standardt T3/T4 60 trim, topmounted with 75 shot of nitrous would be safe, and could net the same goals with a quicker spool time due to the nitrous.

Has anyone ever tried anything like this on a CA? with the finicky timing of these motors i would assume it would be touchy...

don't buy into the nonsense that GT ballbearing turbos came to deliver us from evil. They don't come close.Look at the countless configuratons they sell those turbos in, "still" trying to lessen the turbo compromise. gt28this, 28that, 30this, etc.."should I get the 0.64 or the .86... t2 or t3". Same 5hit all over.

Choose wrong, they suk just like any other turbo half its price.Best thing you could do for any turbo is size it suited to your application while being realistic about your goals.

honestly, i could care less if whatever turbo i use is ballbearing... 2 comparitively sized turbos, one BB and another with a 360 degree journal bearing... will only spool roughly 200rpm apart... HARDLY worth spending an extra 500 bux on IMO.

That being said, I wasnt gonna use an actual gt30r either... ive got a turbo guy that can make copies of turbos for me, inexpensive, with 360 Thrust bearings etc. You completely missed my whole question completely anyway.

I wasnt askign what turbo i should use. IM plenty knowledgable on how to PROPERLY match up a turbo with goals etc.

i have a realisitc goal. 400+ WHP on yes, A CA18DET... high goal? i dont think so... hard to get to? sure but patience will get me there... more efficent ways for a DRAG RACING BASED 240sx with CA18DET to make 400+ whp... DEFINITELY... which is why i have asked my question above.

has anyone ever SPRAYED their CA18DET?

i thought i put it simple enough but i guess i hadn't.

I've seen COUNTLESS Turbo cars with spray on them.

The reason for my question is even tho i'll be leaving off of a 2step limiter, in between shifts with a bigger turbo, there is still a chance that the turbo will for lack of a better term, UN SPOOL itself, and be out of efficency range upon grabbing the next gear.

i've had that happen with T28s...

If i have a T3T4 50 or 60 trim, i can tune it for about 350whp or so, and spray 75 wet shot ontop of that.

In theory this would give me my HP goal as well as a faster spool time and the ability to keep the turbo spooled easier.

I'm not one of these noob's on here that has just come in and asked a random question. DO NOT treat me like one please. Ive done WAY too much time and research into what im doing, but like i said ive NEVER found a sprayed CA other than the UTE on Youtube, and he will not respond to any messages.

Im not going to be doing this on straight stock motor either.

Plan is to get the motor in and running stock for now, drive it around. Then replace head gasket, stud the block, recon the factory rods, clean up the pistons and check them for defects. Upgrade the valvetrain, give a GOOD SOLID tune, and go from there.

Dee knows I'm not braindead like alot of people that have decided to take on these motors. He has told me of COUNTLESS people that buy one, put it in, get bored and sell it. Im not here for that. Im here for success, and im here to break US S13/CA 1/4 Record.

yes i rant, yes i get uptight... deal with it. Ive paid my dues to the 240 world once. Its time for round 2!

feel ya... sortaIf you've seen countless turbo/spray cars, wouldn't your approach be similar - start off with a small shot and gradually work your way up to your target, whatever that is ?Why is spraying a ca18 any different than a sr20, b18, 4ag, etc.. ?

U say 400-425hp with spray. I'd think if u ran a 20g or 50trim @25+psi u won't drop outta boost and definitely hit your 400+ mark... without dope & its potential gremlins.

what ET r u seeking btw ?

I 'believe' "NOS" on sxoc is a t3/t4 + dope fiend. Hit him up maybe

I dont see a problem running gobs of nitrous through a CA18. I really want to do it myself, but I am far too broke to do such a thing right now. Tune it properly and have the motor built properly and you should have no problems.

nitrous is nitrous. All the same precautions you would apply to any piston engine apply.

obviously the tune is EXTREMELY important. I just was trying to see if there were any niconauts with Sprayed CA's that have had success.

Some motors like it, some dont. Thats all there really is to it. That UTE youtube has A LOT of issues with turbo surge which can be FATAL to an engine. But im not sure if its related to the spray or not, due to the owner never re-contacting me.

Dee, im gonna need to contact you when i return to FL, its too bad you cant come up here tho buddy, there is a SWEET 88 sentra coupe with 83k miles on it for $1500 obo, 5 speed and white... perfect for you!

Believe it or not, adding spray to an engine... some react well, some dont... its not as simple as you might think. Tuning is important but with nitrous, i personally believe in -2º for every 50hp shot of nitrous... an SR can take TONS of timing... and i mean TONS!!!!, a ca on the other hand... is a timing sensative motor... and it requires a very little bit of timing to run well..

Honestly, it doesnt matter what size turbo you have, you can drop out of boost. It use to happen to me constantly with my SR and all i had was a (heavily ported and modified) GTI-R T28... also had 256in/264ex cam setup, its all about being able to keep those RPM's up, the SR dropped rpm's REALLY fast. and all i hear is that the ca is even more of a free revving engine than the sr is. Ball bearing turbos do help that because the wheel spins more freely, but IMO thats about all the good a BB turbo has. im trying to stay away from boosting 25+ psi also. Rememebr the key here, STOCK INTERNALS, it wont be a viable record attempt without the bottom end being stock. Im sure if i wanted to, i could do 30psi seeing as CA has Forged rods and Crank, and Cast Pistons rather than Hyperutectic like an SR.

AND FOR THE RECORD... this car will be sub 11.0 when im done... thats all i will promise. As far as i know, the record is 11.2 =)

Well then, lets see it. Direct port nitrous or no nitrous I think, the other forms of dumping it in there are just downright sketchy.

Yeah, direct port is definitely the way to go, i wish i could find a way to fab up a nitrous plate for the CA manifold lol that would be so much easier than drilling and tapping each individual runner etc.

a fogger kit to me is somewhat dangerous... it makes me nervous thinking about it.

Nitrous or bust. Removing the intake manifold is actually really easy when the engine is still in the car. It took me of all people a mere hour and a half.

T67 is a street racer turbo, some people dont seem to understand anymore than BIG POWER doesnt always net low ET's... look at all those 1100hp supras running 10s =) 500hp in a 2500lb car is a 9 second car all day long period end of story. If you dont know how to set the suspension up or get the proper chassis package together, THATS why those supras run 10s not 8s where they should be.

Those supras dont make 200hp until 5500rpm anyway, its disgraceful. Show em how its done mang.

did your sr20 have a lightweight flywheel ?

seen a few other factors cause revs to drop & turbo to stall. Has nothing to do with being on a ca vs sr.Enough 400hp ca18s out there to get solid feedback from.Some have put 20-25psi thru stock innards, quality tuning naturally.Every s13/ca beast I've seen run hi boost and consequently make more torque to get the low ETs.

2500 pounds is rwd corolla/MR2 weight and a few toyota 1.6/1.8s gone solid 10s (even FWD!). CA18 equally capable, so shouldn't be a prob.Spray + lower boost would add an interesting twist vs the conventional 'hi boost' path.

no, in drag racing, its actually better leaving the line with alot of spinning weight, that way the motor doesnt bog as easily. Thats the whole key. Lightweight flywheel is good for road racing cars... besides.. .stock one wont fly apart and take your feet off like a lightweight one would...
