    " I AM SO SMART! I AM SO SMART! SMRT.. I MEAN SMART" You couldn't deduce that from the numerous amount of photos and details of different theoretical plans :P Jokes :P   You'v done it before, fant

    Mate give me a break, its a correctly sized turbo for that engine capacity. I can't run an intercooler so I wanted something that will compress the air efficiently; itl do just fine.

Spanner in the works :bash:

Dads not welded the remaining pieces, and has left them at work (And today is his day off)

Looks like it will be next weekend :(

Should really work on my welding skills, that way it would have been done two weeks ago :P

 

Anywho mucked around for a bit last night, and made a little bracket that holds my fusebox in place

Also my bleeder arrived yesterday (I have never opened a package faster, quite literally tore it open with my teeth :P)

So thats mounted in a decent spot, need to purchase some more hose clamps for it.. Bloody hose clamps will be the death of me, costing heaps :P

 

Ohh yea and replaced my ghetto throttle cable with a new custom length one, choke cable is in as well. But again I need my manifold to route it :(

hey what turbo have you used

i have just rebuilt my 4 and was about to put it in now decided to turbo just need to get a turbo then get a j pipe made up for it

the rest will come later using blow through twin su's

Thats a Toyota CT9..... which I personally think is too small..... but each to their own.

I would recommend a T25 from the first SR20's. Pretty well sized to start with and if you want to upgrade with the same flange (T2)there is endless possibilities. :wink:

SU's are pretty simple things

 

LoL! I used to believe that too! Until I started modifying stuff!

 

Fit the oxy sensors and the mixture gauge before you fire it up! One run on lean and its all over for the pistons...

 

The dyno curve should be interesting!

Haha they are a simple concept, not a simple thing ;)

 

I went for the CT9 mainly because a mate of mine was selling his. That and it came off a 1.3L Starlet GT

A car with DOHC's and a much higher revlimit (Flow requirements).

My mate had a dyno of his starlet, showed very little signs of running out of puff at the top end :)

Bigger may be better, but considering I was going with a draw through setup I wanted something that wouldn't heat up the air too much (Intercooler is NOT an option) :)

As TAZ said, each to his own. I am happy with this for now :) In the end I would prefer a engine swap.

 

Its already ran early on in the piece and I adjusted the carby to very rich! I saw's black smoke coming out the exhaust = me and engine happy for now :)

Once I'm happy with the setup and there are no leaks etc, I shall install the O2 and invest in gauge :)

Ok I changed my mind, moddifying SU's is a pain in the ass !! :P

I'm trying to find out what type mine is and its a nightmare. ID like to run a service kit through it, or a needle and jet at the least. But to find what needle I need I need to know the model not to mention if and where about I'm running rich/lean :P

They put part numbers on their products that don't reference to the actual product :( lol.

 

Umm the manifold has its little piece in for the brake booster, but the rest remains unfinnished :(

ET of completion still remains this weekend.

Leaks in the manifold welded, painting completed :) (Drying on the pot belly as I type)

Got the wastegate outlet welded today, photo only of when it was recently done not mounted. It was raining and I wasnt gonna stand outside any longer than I had to :P

 

IMG_2525.jpg

 

 

Ohh Invested in an AFR gauge :)

Excuse the mount, I was seeking alternatives to the pod. It dosn't look nice, so Ill just go with the good old pod.

Got the nut for the oxygen sensor, but not yet mounted.

Hopefully will have it fully wired up this weekend.

 

Spent too much money today, gonna be in struggle town for the remainder of this week :( lol.

go hard or go home :D

Jeez Evan! I looked at that, thought WTF! That can't work..." Then started scrolling back up the page for something I'd missed! :bash:

Alrighty then, dad still hadn't done anything yet so I just did it myself :P

The coolant lines are complete :)

IMG_4002.jpg

I had to make out of aluminium, because I wouldn't be able to bend steel pipe.

If something goes funky ill replace with copper lines and a steel plate, but for now its fine :)

 

 

The manifold has been installed (with booster line)

Personally I think its a bit too red, so I might buy a black silicone joiner to even things out :)

IMG_2563.jpg

 

The throttle cable remains, and now I have to relocate the bleeder as the coolant lines are in the way (Not difficult)

 

EDIT:

Ohh and very annoyingly the AFR gauge was narrow band only, the sensor I have is wide-band.

Took it back to auto-barn, they said they will exchange it Tuesday (They don't stock many wide-band gauges, and need to call up to get prices)

And..... I drove it today :D

Throttle cable setup done and took her for a drive to the petrol station :)

It was only only 5 psi because I don't have the AFR gauge yet (This week me thinks)

 

Anywho its back apart again, I have a radiator to patch up :)

Few bits and pieces to do now:

 

* I'm getting the carby to turbo pipe TIG welded (The old brazing was leaking)

* Bracket for the carby to stop it shaking (wont be hard)

* Wideband O2 gauge (This week maybe?)

* Exhaust flange so I can continue the exhaust, I can't have it all one peice

* Radiator leak

 

I also will need to get carbon seals put in the turbo, figured this would be a problem but hoped for it not to be an issue :P

The only reason it needs it is when I sit still too long, it sucks the oil into the turbo and I get a nice plume of smoke following the car :P

 

Anywho it has been driven :D

good work interesting to see your power figures once finised.. those coolant lines don't look like they'll flow they look kinked in the pictures.
