Datsun 120y Ca18det

Recommended Posts

I thought I would put some details up of my Datsun 120Y.

When I first bought it, it had a stock CA18det, stock ECU, 5 speed manual, R31 LSD diff with leather interior and the usual surge tank & pump setup. I had another engine that I pulled out of my Bluebird TRX S3 sitting aside, so I pulled the stock CA18det out and put my engine in, which had the following specs:

-Arias forged pistons

-ARP head studs

-Cometic head gasket

-Stainless low mount manifold

-Garrett GT2871R (welded wastegate flapper)

-Tial 38mm wastegate

-Microtech LT10s

That engine made 308rwhp (228rwkw) on 20psi with the manual in the Bluebird, but I wanted to go auto so I sold the 5 speed and had a 3 speed Jatco built and used the S3 Bluebird bellhousing, directly mating the box to the CA18det. The box is reverse pattern, transbraked with a full manual valve body.

I also sold the GT2871R and bought a GT3071R, and had a steampipe high mount manifold made to suit. Also stepped up to a Tial 44mm wastegate.

First day owning the car.

The Auto was matched to the CA18det, and the converter was a little low, so it struggles to come on boost and is a little laggy. I raced the car like this and it ran 12.6 with no boost off the line. So the solution was either converter or nitrous, so I took the nitrous option :D

The nitrous was fitted (50 shot) and wired up the the Eboost, and it was set up to cut the nitrous at 15psi, and the engine should then have enough boost and load to push to 20psi or whatever the boost was set at (usually 22psi). I then went straight to Powercruise 12 and spent 4 days sideways around Eastern Creek and revving the car to 7000rpm in the Powerskid comp, and not a problem in the world, didn't miss a beat. The gas helped the turbo come on straight away and I barely had time to shift gears with the auto, especially with the 14" stockies on the back. Also fitted some Centreline Convo Pros on the front.

I then took the car to WSID to test the gas on the track, and ended up running 11.92 @ 114mph, but then the engine let go over the line. So, after much thought of what I want to do, I have decided to build another engine, this time a semi serious setup. Mind you, the above combo lasted 4 years with violent RPM all day everyday, so I was more than happy with the life span it had! So, the new specs are:

-40 thou Wiseco pistons.

-RPM I-Beam rods.

-ARP rod bolts.

-ARP main studs.

-ARP head studs.

-ACL Race bearings.

-Tomei Procams 260 Duration/8.8mm Lift.

-Tomei adjustable cam gears.

-Tomei valve springs.

-Mild porting (more smoothing ports) on the head.

-Port matched inlet/exhaust manifolds.

-Garrett GT3076R Turbo.

-Tial 44mm Wastegate.

The bottom end will be built in about 2 weeks, just waiting for a few cranks to be crack tested.

I have entered Supernats (November @ WSID) and Summernats this year (January), so car will hopefully be running again in September/October.

Engine being built be Dominator Engines in Guildford.

All videos of the Bluebird & 120Y can be found here: ******YOUTUBE LINK******

Thats really all I can think of right now....I will have many more pictures of the new build in the next few weeks.

Car has run 11.34 @ 119mph @ Supernats 2008, and the car is currently having a few read end mods done, and it should be back @ WSID with more nitrous to crack a 10, hopefully by the end of July.

Have been giving it more hell too :D

OK Update.

Slapper bars are now fitted to the car, racing next week (19th of August).

Took the car to Castle Hill Exhaust for a tune this morning, turned up making 308rwhp on 25psi, ended up leaving making 324rwhp @ 23psi Very happy, car is a weapon up top now. The gas is also programmed to turn off @ 20psi and it holds 20psi till you let the transbrake button go, cannot wait to race on Wednesday!

Nice work!

The launches got much better in the later runs.

How many RPM are you pulling? sounds like lots :devil:

Long time since updating but I have just finished putting the gearbox back in the car, now fitted with a higher stall converter. Also fitted a 5 point harness and will be racing the car at the 25th of July Test and Tune. Hopefully a 10 second pass is in the bag :thumbsup:
