Hey Fellas,
Im buying a '81 TE gemini and i want a turbo engine for it but at a bit of a budget! I have looked at the 4ZC1 piazza motor, but i think i can get better power results out of a CA18DET motor plus this motor is fairly common. I have also looked at a SR20DET but cannot afford this motor so i think i'll do with the CA18DET!! My question is what will i need to fit this engine straight into the gemini? I wanna try and do this myself but If i can't fit the engine myself then ill have to get some1 to fit it for me! Thanks fellas!! Justin

man have a good think about an FJ20...
either you will definately be able to fit yourself.
get custom engine mounts made up and go from there. there is a heap of work involved in any conversion so dont think that it will just be a little weekend job,, that is if you want it to be legal.

what ever you chose, do a search
this will tell ya most of what you need to know
THEN once youve found some stuff out yourself
come back and ask more specific questions

the only cost differecne in a ca, fj, sr conversion is the price of the engine. the conversions are all basicly the same.

fj20-
not including the cost of the box. to put it in stock i would say have $4000 ready to flush.
but as u go im sure u will speind more.

VERY quick run down (these are cheap prices, may cost more, but not less)

engin and box - $1500
bigger fuel lines - $100
surge tank - $100
bigger fuel pumps - $200
rising fuel reg' - $200
custom mounts - $150
custom gearbox mounts - $150
hydrolic clutch peddle - $200
custom rear sump - $200 - $300
custom oil pick up - $150
custom exhaust manifold (stockone hits the fire wall)- $600
brake upgrade - $450

(im sure somethings will cost a bit more and somethings u may find cheaper but that all adds up to $4100)

then im sure if your getting a custom manifold u will get a bigger turbo. and im sure u will want a FMIC. so thers another $1500-$2000 ontop.

+ engineering- $1000ish (4 engin, gearbox, FMIC and brakes)
+ insurance - easy over $1000
+ rego - $500ish
