i have a small turbo off a CA18 nissan 200sx..
anyone know anything about it? its a little garrett turbo.. idk, maybe a T2?
-
The good people at google say it's either a t2 or a t25. Any p/n's?
-
its a T2.. a little looking on wikipedia (friggen encyclopedia no less) lead me to the answer..
a little reading about the CA18ET told me what i wanted to know about the turbo. now i need to find some maps, and figure out how much air this thing is good for.
is this T2 turbo going to be similar to a factory VW diesel K14, or T2, if it were fitted to a diesel engine?
or will it not spool correctly since its a gasser turbo? ive heard gasser turbos dont spool up the same as diesel turbos..
-
i did a search and this thread seems to conclude that gas turbos don't work on diesels

that was a BIG T3 off a 2.5L engine.. it would have been horrible on a diesel.
im talking about a wee little T2 is all.. its off a similarly sized (1.8L) engine also. much closer in size than a 1.6 and a 2.5
but it doesnt even matter, the T2 is going on my 86 GTI. i re-drilled the flange on a stock single downpipe manifold to fit the turbo.
i have all the bits needed to convert CIS-Lambda to be boost friendly also.. so all i need to do is put all of it together, and get it running.
its gonna be sweet having 2 BOOSTED CARS!

???
that guy was using the smaller mitsubishi turbo, the size of the engine a turbo comes from doesn't give u anymore than a vague idea of how well it will work.
obviously tho a t2 off a 1.8 nissan will work well on a 1.8 vw, aside from that i'm sure the nissan probably revs 1000rpms higher and flows much better, but when you're deal with that small of a turbo its kind of irrelevant

that big turbo is on that 1.6 diesel now and spools just fine even tho its a gas turbo and wont work. from my experiance the stock turbo thats on the sr20det is rather small but that engine flows extremely well and revs very high.
the 2.5 engine had a mitsu turbo which is just a hair smaller than a t3 is and 2.2 came with a decent sized t3. the super 60 is what i would call a large t3. the mitsu im using has some lag yes but im using a large front mount. i will have a video of it not spooling up at all soon.
the size of the displacement is not so relavent. the 2.2 and 2.5 share the same head and everything only difference is the 2.5 has more stroke. the mitsubishi was put on the 2.5 for basically instant spool. faster than the vnts that were on the 2.2s in fact and were out of breath by the time 4 grand came around.
the best thing about the bigger gas turbos turbine side is the lower egts i seem to be seeing at around 20 pounds of boost.
look at the compressor map. nothing else.

were not talking about SR20s tho..
and glad your turbo worked out for you..
that mitsu turbo has gotta be way out of its efficiency zone @ 20 psi tho.. there only efficient till about 15psi, or so ive read..
-
thats why i run around 15 usually. it seems to just be working great around then tho. i might try it higher if i get gutsy. i might put the garrett on the car if i get bored sometime since i know its good up into the 20s.
the sr20 is the one most people run because they ditch the CA18. my friend had one make over 500 horsepower to the wheels. my point is that they flow alot of air and rev very high.
im actually running the front mount off his old car on the rabbit right now.
that turbo will probably work great for what your looking to do be really torqey down low and have no top end.

im honestly glad that you proved me wrong.. it means i have more useable turbos for my diesel.. sorry i was being a nay-sayer the whole time.. i was just going by what someone (who i thought knew what they were talking about) had told me about putting gasser turbos on a diesel engine.. im glad it indeed DOES work tho..
but, im not talking about SR20s, or CA18s or anything like that.. im simply talking about the turbo off a CA18.. i have it in my possession, and its bolted to an 8v VW exhaust manifold.. thats cool that the SR20 turbo is small, and can keep up with HIGH rpms..
and what do you mean about the turbo having no top end? im not going to be spinning the engine past the stock red line anyways..
are you saying that its gonna run out of breath before the rev limiter?

that turbo if im not mistaken is smaller than the mitsu im running on the diesel and they ditch that like the plague because it spools super quick but makes no real power. a decent sized t3/t4 has decent spool on one of those motors.
my experience with having no top end would be with my stock shelby charger. it would spool up super quick with the stock garrett but even with the stock head the turbo would fall off by the top of fourth and fifth gear in the higher rpms. it just didnt make enough power up there because it was so small. id rather have a car that has some lag time and hits like a freight train im fine with waiting or downshifting. when the other guy gets into the higher rpms where your going to be at for longer before you change to the next gear i dont want to be out of my powerband. the car would rev to 7 grand but just didnt pull past 5 and felt like a dog. first through third was great but after that nothing. i was out of the efficiency of what that turbo could do because it was to small.
and as i said before if the head intake and exhaust wouldnt have been ported like crazy this turbo wouldnt have worked. it would have been useless
-
sr20 and ca18 had similar turbos, it really depends what ca18 it came from tho

is there more than one CA18ET?? it was a single cam, 8v 1.8L nissan engine.. non-intercooled, idk what else to tell you about it..
-
either way id go with a slightly bigger turbo i would think. depends if you make the top end flow any better i guess.

im not doing anything to the engine.. im bolting a turbo on, making oil lines, hooking up the boost sensing WUR, and installing a boost gauge..
im not building an engine for boost, im gonna see how much power i can get out of a bone stock engine..
im not building a race car. i just want more than 85 rompin', stompin' horsepower.
honestly, the engine spends most of its time under 4k rpms anyways..
is it really gonna be THAT bad? is it gonna be all out of boost before i hit the factory 6250 rpm rev limiter?
the next engine i build for the car is going to be an ABA/16vT.. it WILL be built specifically for boost.. and will have a better suited turbo on it..
im just making due with what i have for now..
my turbo choices are:
T2 off the nissan (small crack in in wastegate, otherwise in VERY good shape)
T3 off a 2.2 chry (needs rebuild)
TE04H off a 2.5 chry (needs the band clamp that holds the exhaust housing to the center section, and a wastegate can)
K24 off a VW diesel (boosted fine, no issues after i fixed the wastegate)
K26 off an audi quattro (unknown condition, no wastegate)
what turbo, of the 5, is best suited for a stock GX code 1.8L VW 8v engine?
-
see im into the old turbo dodges and know about those turbos fairly well. i dont know how much air the top end flows and such but i do know that the 2.2 has a 8 valve head and the stock t3 that was on my car would basically sit there and spool. a super 60 on a stock head wasnt horrible on a stock head either and that turbos good for 300hp.
no its not going to be that bad. is anything done to the aba to the bottom end to run boost? if not i wouldnt go over 7ish psi. depending on the CR of the engine.
if you plan on building the next one way better i would go with something you could upgrade easily tho and the t3 is great for that. and if you so with a little work that teo4h wastgate can should be able to work on the t3.
the teo4 is good for about 190ish
the t3 good to 225ish.
im running the teo4 on a 1.6 i see no reason to not run bigger seeing as it has bigger displacement and more broad rpm range. if your going to see how much power you can make why have the turbo be your downfall. why not the botttom end.

im not running an ABA in my car now, im running a GX.. its an 8.5:1 compression 8v engine.. perfect for boost.
and when i build up the ABA 16vT, its gonna have ARP studs up top and holding the crank in, metal head gasket, as well as ARP rod bolts if i can find them. most likely going to use the stock ABA pistons. everyone says there good for about 300hp, if you can keep the engine from going lean..
i modified a stock VW manifold for the T2 turbo already.. if i decide to go with a different turbo now, i would need to spend quite a bit more money.. i would have to buy a T3 manifold off ebay, and then pay to get an adapter flange made for it so i can run the dodge T3 pattern..
screw it, the T2 is going on there.. i will decide for myself if i need a different turbo on there.. i want my boost down low anyways, and it sounds like this T2 should darn near be spooled at idle.. like i said, the T2 is bolted to a manifold already. it needs boost tubing and oil lines to run. all the other turbos need considerably more work/$$$ to use them..
when i build the ABA16vT, im going to probably use my K26, or else buy a better T3 turbo.

well there was only really one ca18et but, theres also the dohc ca18det, i just said ca18 so i wasn't sure which one u had. i don't have a compressor map but for the 8v it will be a nice little turbo on there. the dodge t3 or the k26 would make the most power, and i know the k26 has been used on 8vs before (mostly abas) but it doesn't sound like ur looking for peak power, just more power on the cheap. on an aba 16v, i'd really look at what other people are running, aba 16vs are really common and butt loads of people have already experimented and found what works and what doesn't. aba bottom ends are awesome. most people will push an aba bottom end further than a 1.8t bottom end haha.

thats what i did other than the paying to get flanges made you can buy them on the net. buy a stantard t3 flange and a chrysler t3 flange weld them together and one side bolts to your header the other to the turbo. not that bad honestly. and the header from china off ebay is like 110 to your door and is actually very decent quality. even weldable even tho its cast due to the high nickle content
