Pulling CA head off: OPINIONS

[mikesim]

so, i've made a list of what i need to disassemble the head and rebuild it. Can i assume all the CA18DE parts on the head are the same? that means, can i rebuild a CA18DE head, Port and Polish it and put it on a DET?

Fuel Filter 16400-F5100Oil filter Fram/Quaker State 3682 (i've checked this one out, it is definitely longer than the CA18DE one 3400)

NGK PFR7/BCPR7 spark plugsExhaust manifold gasket 14036-D4200 (EXA 1.8, S13 CA18) Four separate pieces Intake manifold gasket 14035-D5710 (CA18 all) Injector rail to cylinder head Intake manifold gasket 14035-D5711 (CA18 all) Injector rail to intake runner Valve grind gasket kit 11042-51E25 (CA18 all)Thermostat 21200-V0201 (CA18 all) 82.0 C Fan belt 11720-V7301 (CA18 all) L = 855mmCompressor belt 11920-V7301 (CA18 all) << X2 for Power steering and AC

Water Pump** CA18DE Pulsar NX B150-1350 << i have read that this is the wrong one if i continue to use my clutch fan? plz confirm

Turbo outlet flange gasket 14445-26E00

my goodies are:Tomei 1.5MM metal Head gasketARP head studsTomei kevlar reinforced timing beltS15 T28 turbo(1986.5 RX7 turbo) 550cc injectors - tan topsApexi S-AFC 2

this isn't overkill is it? am i missing anything important?

Use the water pump off of an 86 200sx. I'm actually not sure which year it is, but it came with a ca18et and was rwd . Infact you might just wanna get a electric fan and be done with mech one all together. I'm sure there are plenty of ppl still using the mechanical one though.

get the 86' 200sx turbo H2o pump. I did and it is IDENTICAL to the one I have. The difference is that the cutout for the center of the pully is different, and if you use the DE pump and a clutch fan it wears out the bearings and you'll be replacing that pump in about 6 months or less. Or as suggested, just get electrics..

thanks guys. i read that about the pulsar pumps after i had already bought one, and it was on back order, so i was forced to keep it or pay 25% restocking fee.

i'm thinking an electric fan and a new rad would be a good idea anyway.

so the DE cams are different than the DET cams. will i see a difference in power? at the very least i don't want a loss, but will i have compression issues down the road?

Who has had a problem with the DE water pump? I couldn't tell the difference between that one and my original. They look identical, so why would the bearings wear out sooner? I'm a little suspicious someone lost a DE water pump and assumed it was from the fact that it was a DE pump.

They only had problems if the used they DE pump and the stock clutch fan. If you run it w/o any fan on it, they seem to work fine. If we ever get our old archives back, I'd look it up for you as there was a whole write up on the thing. But since that's not available, talk to Sean (NeedCAforS13) about it. He's the one that figured out the difference. I have had the DE,DET, and ET pumps all in front of me at the same time and I know for a fact that there is a difference. The ET is the one to use IMHO...

[NeedCAforS13]

if you run a fwd pump with a rwd pulley the hole in the pulley to go over the pump neck is bigger. It caused my motor to shake pretty bad at idle and it also ate up a belt in about 2 months. I just got a fwd pulley on there about a month ago, and there is no more vibration at idle, nor is it tearing into the belt. If you want to run a pulsar water pump, get a pulsar water pump pulley... I can post pictures later, I don't have time to upload them right now (on my way to work)

thanks for the info guys. i'm hoping my new setup will run just as reliably as stock.

what size oil and water lines are there on the turbo? i'm thinking of going with stell braided.
