After seeing this neat ser2 TRX bluebird on the side of the road I couldn't resist taking a look.
Then seeing the factory looking TURBO sticker on the back I rang the phone number to see what was in it!
A standard L20B... No turbo... But still I couldn't fault the body work, no rust, immaculate interior ect. And when
I couldn't get the idea of a turbo bluebird out of my head, SR20DET engine conversion came to mind! Bargaining
down to the grand sum of $800 (w/o reg) that sealed it! After a few days, my brothers mate came and said the car
used to belong to his wifeís parents from new, and that it had been serviced religiously with mobil 1 oil! It shows,
the engine is in great condition, hasn't used a drop of oil with in the last 10 000, with 240 000 k's on the clock.
Anyone want a great L20B engine and 5 spd, cos it's for sale.
Now with the SR20DET in place Iím loving it!
The donor parts are from an manual turbo s13 silvia front cut, showing 75000k's on the clock (if u trust that) and
completely standard apart from a pod filter, it's exactly what I wanted.
Pulling the engines out, they are roughly the same dimensions, just a lot more shit hanging of the SR. And with the front cross members sitting side by side u can see they are same basic configuration. But the s13 is 70mm wider in track
The fun part! After measuring it all up and dummy fitting the s13 cross member I found I only needed to
slot (about 2mm) the rear bolt holes in the rails and make new front holes, so I welded a piece of tube into the rails, easy.
Now slotting the engine in and resting on the factory engine mounts, the engine sits very close, but just
right, to the fire wall, giving me a problem with the inlet runner clashing with the clutch master cylinder.
After a bit of head scratching the only solution was to recess the fire wall 20mm and fit the silvia clutch
master cyl which is 10mm shorter. There is space to do this as the clutch pedal box has 20mm spacers
to the firewall.
A VL commodore air box is just right to bolt the air flow meter to and fits nicely in the bird.
I made up a surge tank from a piece of 3" stainless tube and mounted a bosch fuel pump and filter on the bluebird bracket next to the fuel tank. The factory bluebird electric pump fills the surge tank! I also replaced the standard 1/4" fuel line with a 5/16" line, but the return line is still the std 1/4". No probs yet.
A few extra bonus's were the power steering carried over with the x-member, I only needed to mount
the reservoir. And the silvia brakes too, that are a lot better than standard bluey but not fantastic.
Extra info, more pics to come.
On suspension, the track is 70mm wider which puts standard trx rims right out to the guards so much that they scrub with 195/60 tyres! A roll of the guards will fix that. I used the silvia strut tops and modified them to sit the top about 20mm wider on each side. Had far to much camber and no droop at std ride height with the bluey tops. Perfect for a circuit racer though. I cut the bluey spring seats off and fitted them to the silvia struts, so uses the std springs.
I also fitted the silvia instrument cluster into the bluebird dash. It's not finished but all working, speedo is
spot on (same diff ratio), and everything else, lights ect, wired in. I much prefer it over the standard, I can
actually tell what speed Iím doing! And I love the 7500rpm red line!!
An intercooler also now fitted into the nose. Its a generic 450x300x76mm bar and plate type that fits beautifully with only the center support modified! I made up 2.5" steel pipe work right from the turbo to butterfly.
Next on the things to do list are a full 2.5" exhaust, but before that Iím going to fit a silvia IRS same as I did
in my VL. This will be much easier as the bluey has coil overs in the rear already. Main reasons are for
an LSD as the H165 and H190 LSD's are very expensive if you can find one, but the R200's are more common.
It will bring the rear track out to the same as the front, and of corse be much stronger! Oh and I love IRS...
Also planning on fitting the climate control and a/c.
