I´ve finally decided it was time to write my own project thread.
I have a phase 1.5 GTT in a prima shell. Phase 1.5 has basicly parts from both phase 1 and 2. Fe the sump is a phase 1 type but carb and associated piping is phase2. It has been nice to buy parts since you usually can´t be sure which one is it.
ENGINE&POWERTRAIN, past
I did the full engine overhaul 2 years ago. I Did some basic head work and fitted CatCams 265 cam too because head flow charts I got "before" and "after" didn´t show any point in choosing wilder cams. When I got the car running again, the plan was to keep it quite standard and in everyday use.
"upgrading" started with FMIC. Soon I notice that the cooling of the car wasn´t sufficient. Mocal cooler and clio16v rad was fitted.
Hunger for parts got worse, so I had to replace my standard exhaust manifold with my DIY equal volume stainless manifold. It seemed to improve boost rise but I have no power charts to support this.
After making the manifold I bought a T25 from 200SX. Scoff sold me 0.49 exhaust housing to improve the lagginess of the turbo. T25 needed bigger and better downpipe, so I installed DIY onepiece downpipe. (I´ll add picture later).
When choosing to upgrade my turbo I also decided to convert the 5 into EFI. Scoff helped me choosing the right sensors and also made me superior "plug-in" loom for the adaptronic I purchased.
I made the first intake manifold with manual milling machines. It had some leaking issues which required a lot of work. Also the runners seemed to be too short, and the plenum has problems flow-wise. Still, in the end it worked quite well. I managed to get 2 powercharts before breaking my gearbox. First one was only upto 4000rpm with decent boost, and the second one was to make MOT guys happy (a chart with just under 20% power rise). Week after mot I broke my gearbox, and while waiting for new I decided to make a second, far improved, intake manifold.
INTAKE V2.
I decided to re-use the throttle body and those 431 injectors I had. Everything else basicly changed. The runners are longer now, injectors mountings are in the runners. Plenum has improved design also removing the difficult bend just before throttle body. Fuel rail is stainless now, with fever connections that could leak. Most of the parts are milled with cnc to ease the assembly process. I'm planning to anodize (without color) the manifold to improve finishing quality and add chemical resistance.

FUELING&IGNITION
At the moment the car is running standard fuel. The second intake manifold and fuel piping has been made to accept also E85 fuel. I´m planning to buy the zeitronix E85 analyzer kit and take the signal into the adaptronic to change fueling and ignition timing. Connecting a WB and knock sensors to the car will make it full "flexi-fuel" spec.
The Ethanol content sensor however costs a fortune and therefore the plan is to first map the car run on both fuels separately and compare the gains. If there aren´t enough, I won´t proceed with this. The adaptonic doesn´t currently have a function to directly accept this flexi-fuel adaptivity, but I´m planning to use my intake-temp sensor channel to adjust the fueling and timing.
SUSPENSION
Nothing special really. Spax suspension kit, clio16v brakes, momo 15x7 rims.
INTERIOR
Sparco seats, carbon door cards. Most of the interior removed. I will install a roll cage as soon as I have time and can afford it.
I´ll add updates to this thread whenever something interesting happends.
