Im back! Let's keep this thread rolling

Right, so I spend another half year to do the reasearch (Nasioc power bragging and tech section) just to select some high-quality parts. Finally I get them all just after my traditional holiday Spring Fest. Here we go then!


Its Perrin Signaure front mounted intercooler, black core with red coating pipes, I just love it so much. And also Perrin 77mm big maf V2 induction kit


DW850cc high resistance injector for enough fuel



Rota SVN-R 18*10J ET30 in flat black


Blouch Dominator 1.5XT-R with 10cm3 hotside

Okay, everything here, I spend 3 days to get them fitted properly without any problem. Thanks God! The only thing is cutting front bumper to fit the FMIC. I put the cut bumper into paint shop to do some details (size, gap and etc)

Some fotos during the process




Its pretty much finished, needs some black vacuum pipes to replace the blue one to match the colour of engine dress-up!


One thing I do moaning about during all lots is Perrin V2 big maf been an arsehole which cant really fit Perrin FMIC. Two thingys squeeze each other. But in the end I made a bracket for the induction and solved the problem!

They are what I get off from my old setup, VF37 twinscroll turbo, twinscroll up pipe with 38mm tial ewg, OEM stanless steel twinscroll outlet manifold (WTF, why Japs always offer the best best quality parts for their domestic!!), twinscroll downpipe and some other small bits which I cant actually remember.



And this is my comparison among 4 different turbos
upper left: VF37 (thrust bearing)
Upper right: TD06-20G 8cm3 (thrust bearing)
Lower left: TD06-20G twinscroll 8cm3 (thrust bearing)
Lower right: Dom 1.5 (equivallent GT3071R, ball bearing)

Okay, following step is to Tune! Im into tuning scene for 3 years so I merely think I just can handle this with my lil knowledge. It turns out quite nice. 345whp and 310wtq with pump gas Ron97, between Mon 91 to 93 (bad petrol in my area). 24psi@4800rpm tappered down to 23psi@8000rpm under 119F intake temp. So Im expect turbo would be spool up quicker when winter coming. Target AFR is 11.3

This is my target boost map


This is timing map when Im with VF37. Its not suit for 30R because the timing during the spool up is too high to get enough manifold temp. Have a look at this, you will instantly find out, around 30 degress base timing while turbo kicks in. Its not good!


Let's make this point more clear with Airboy spreadsheet method. In this diagram, we clearly spot whats timing going during the spool up and full boost. Black curve is actul timing Im running with. Red is timing in the Map (theoratical timing). Now we can see the different. Actual timing is way higher than what I write in the ECU.


So, I did 16 runs on Dyno to tune the timing and made turbo spooling up as quick as possible, finally I got the almost perfect base timing.


This is the trend of new timing. Black and Red are almost overlapped. Timing is Done!

Again, this is diagram of timing, from different view. I made the timing as much smooth as I can.


And this is timing advance table. I made them quite easy to see and to use. I know some people here are the gurus of tuning stock ecu, but just let me explain this. In the normal stock ecu, timing advance looks very complex and make you dizzy sometimes. Basically, ECU caculates and uses the timing as Total timing, which means Total timing=base timing+advance. I dont do it seperately, I do it as whole lot. Then I reduce the timing advance, at last I put base timing into the ecu timing table. In this way, I made caculation very easy.


This is stock timing advance, now you can see what I mean. stock advance table is so complex and not in a regular pattern.

I made target AFR as easy as I can. Three different area, thats it! Its running pretty well.


This is how AVC-S works on my ECU at the moment. If AVC-S covers too much after full boost, there will be huge Knock occured.

The rear diff is almost identical from JDM MY02-MY06 but totally different from MY08-MY10. . And from the traditional name in my area, we call MY01-02 as version 7, MY03-MY05 as version 8 (early model and late model, apparently), then MY06-MY07 as version 9 and etc.
thanks for the info! i love your car keep up the good work!

Just had a good lunch with my colleagues, haha

Tuning is done! then during the next few weeks, I did some fine tune like close-loop fueling and maf scaling. My scooby is running good power with good petrel economy.

Is it end of my whole scooby project? Narrrr, I dont believe myself saying that bollocks. But what should I do next? Forget about that, Im using my scooby as DD for over 6 months.

As usual, Im surfing Nasioc everyday and quite enjoy to read other people's build and member's gallery. There is something starting to grow on my mind. Widebody sounds alright to me, some aero bits are good too.

p.s. to be honest, I was thinking widebody long long time ago but I was working on power unit at that time, so widebody project is never counted to my whole plan. It only exsits in my dream.

Is it the unique oppurtunity for me this time? What should I prepare for that? Right, back to normal, Im doing research again which what Im good at. Another 3 three, no, 5 months, hundreds of photoshopings, thousands of advance search on Nasioc and google in the mid night. Finally, I made up my mind, Widebody officially coming into my new project.

APR is good and wide but its too round (no offence, different personal preference), L'aunsport is brilliant but its too expensive which I cant afford. So I choose my desire rational. I want something looks Fat, Muscle, juicy and mean. Kakumei looks perfectly to meet what I need. And also Kakumei is Cheap and Made in Taiwan which is as a part of my country (one day!)

Meanwhile, I ordered Ichiba racing spacers to fit widebody. But things getting dodge. The seller on Ebay US tricks me as the spacer is for MY05 STI 114.3PCD 12*1.25. But when I recieved them, its not as same as description. It is actually for EVO coming with 12*1.5. That sucks and bad feedback straight to the seller. FxxK that!

I went to local dealership with the spacers and got the all bolts replaced by Subaru genuine parts.


Kakumei Widebody kit coming on time, good one!

Today is Friday, I feel exciting coz weekend just around corner.

This thread, I was trying to cover as much detail as I can because it is over 3 years build, a lot of old fotos during the whole process of this project. I know this is not some big power build or some really eye-catching build, I consider this thread is my part of memory rather than show-off, its treasure of my life. So people, please treat this with respect. About 1,300 views with less 15 replies, fair enough, this is life but I must accept, innit?

Sorry about moaning, lets keep it going!

Now, this is most painful, I start to cut the rear wheel arch to make more room for suspension travelling and tyre clearance. Widebody fitting manual indicates 15mm will be enough but I wanna more low on my scooby, so 30mm sounds ideal for my purpose. Cutting is hurt just like cutting myself but thing needs to be done. Its not hustle.


From the pic, we can see its two piece structure.


Okay, lets do test fitting of this widebody.

Fuel cap is on, widebody factory did pre-cut.


Left quater is almost there, looks alright, need some line-up work later.


From underneath


This is fuel cap's bit

mainly, kakumei build the widebody kit in "alright" quality.

whole kit made by fibre glass, my one fits the body curve pretty well but rear quater and door panel aint lined up in perfect on the passenger side (fuel cap involved), need some shaving works.

Due to its price, I would say this kit is not bad!

Nice! I like the wide body!

I think you should have stayed twin scroll the 1.5xt-r is still a nice turbo though! I'm thinking about going with the same one.
