I guess thats the advice that I needed. Someone to tell mw what to do.

I think the decision is made. go nuts with the a15.

cheers for the help folks.

Stick with the A
More good stuff avail

I'm doing what I'm doing because I want too

Ask rego dept for your requirements

Yeah righto dattoman. Is all the stuff that you have listed neccessary, as must have stuff done, or doing for the projects sake. This is good infomation. Basically the ca18det is out for the count.
so its a ca18et/ E16 / E15.
The A15 is sounding better at this stage, though a ca18 would be awsome.

I can get a hold of an E16 pretty eaisly. I have heard roumers that they bolt to an A series box directly bar one bolt, which is just a new hole in the box somewhere.

Wonder how many ponies an E16 would put out vs the A15?

whats the deal with that? They do HP/weight rather than engine capacity/weight over there? A little hard to police without having a dyno in the back of every police car..

Well you wouldn't use the 60a box with the CA anyway
You'd use the 5 speed that comes with it like I'll be doing

I've had long talks with rego dept about the CA conversion into my 1000 coupe
They were not at all keen
Once I explained I wanted a later model efi engine in RWD and the fact the only way you will get this thru Nissan is 1.8 or 2.0 they softened alittle
But they were against any form of boost

However
I'm still going to go ahead with my CA turbo setup
However my CA is a SOHC not a big head DOHC and after explaining this to them they gave me verbal approval but won't put anything on paper till they see it in the car

You will need suitable suspension , brake and chassis mods to get anywhere near rego plates


This is my theory (for my own car)
CA18ET
Factory computer
Factory 5 speed that came with the CA
Custom tailshaft
R31 Pintara diff with disc rear (R32 2 pots actually on vented disc)
4 link rear setup (no more leaves)
Front brakes will be my hubs (in alloy) but adapted to 294mm WRX 2 piece discs
AP 4 pot calipers from MGF Trophy.
Balance bar and twin master cylinders
Hydraulic clutch setup (hidden under dash)
Chassis strengthening and seem welding
Coilover front setup

Thats just for starters

If you want a cheap HP solution jump on the turbo manifold bandwagon and go that way with an A series
I will also be doing this for my wagon with old race motor.

Its still a little confusing. I reckon that the A15 will end up costing more that buying a ca18 or similer to get it technologically the same (efi, crank angle sensor, turbo etc) , since I have to rebuild the A15 to suit, and a low k jap import shouldnt need a rebuild yet since a standard one would be more than enough to start with at this stage.

Its the installation that is the question. Will it cost the same to install the a15 as the ca?

Its the install that I dont know anythng about.
I have to go custom exhaust anyways for both
move engine mounts for both
new raditaor for both
move the battery box for both (larger radiator and neateness)
new clutch for both
new diff for both
new prop shaft for both since 60a 5speed is planned.

I expect that the ca would cost more, but is it significantly more?

i reckon allow a bit more for the ecu, probably more like 1500 and at least another 500 for tune/ setting up. I no with my setup i had to buy a vl fuel pump $200, injectors (4) $100), regulator $100, the ecu and tune/fit up was nearing $2500 and that was a base model e6x haltech still single coil etc, throttle body $50, depending on your fabrication skills at least $1000 for manifolding/ dump pipe or do it yourself, intercooler and piping $300, then things you dont think of like clutch $800 (i went overboard first time round) etc. Stocko decomp motor will take a bit. Or the alternate suck/blow through for under a grand all up, depends what you want from the car i guess.

hmmm that does sound cheapish, but yeah was planning on goinf efi. Since this is not the daily driver anymore, and there is no hurry on stuff, i wanted to go a bit silly

Dazzaute I am not quite sure how much, probably a bit more but it was just a conservative estimate. But where the weight is along the wheelbase also has an effect.

The computer is probably the most expensive thing, but that is assuming that you go injection. If you use a simple SU style carb on a suck through set up, it will be quite cheap. You should be able to get a turbo for less than $200. If you can do the work yourself, a rebuild kit is $100.

Good luck

I saw some of those photos of a ca 18det into lagwagons 1000. From memory, its about $2500 for a front cut silvia. You could do a direct transplant touching nothing and I reckon it would come out about the same. as the a15 jobby.

In my guesstimation of 15 turbo job, i reckoned
rebuild a15 - $1000
computer - $1000
turbo - $800
custom pipe work to make it fit - $500
misc - $800
= $4100
plus everything else!!
The a15 was planning on going efi, crank angle sensors, rollers, double valve springs etc, the whole bit. so basically a modern efi motor, but with the heritage and simplicty of transplant.
But with hp figures of about 170hp at the flywheel for a standard ca18det, i would think that you wouldnt get that sort of hp from the a15 without serious mods.

Is my logic logical??
