View Full Version : Tsia's 1A1 single build
Hi guys,
Car is now in the hands of MK Autos to sort out the single build, so I'll start out with the spec:
Rebuilt engine with 86.5mm pistons
BW S362 turbo
Whifbitz twin wastegate manifold
Turbosmart twin 40mm wastegates ( & screamers ;) )
Turbosmart supersonic BOV
Custom fabricated pipework (FMIC, exhaust, screamer pipes, downpipe etc)
Link G4 ECU
Mishimoto IC & rad
So without further ado, here are a few pics. Plenty more to come after these!

The freshly made screamer pipes connected to twin 40mm turbosmart wastegates

Turbo mocked up with custom IC pipework

And the freshly made downpipe
Anyway, lots more to come! :D
Nice :cool:
But why not rotate the compressor housing to route the intercooler pipe out of sight? That's what most do and it llooks neater :)
No idea, after seeing a few other pictures of the fabrication work I'm pretty confident it's going to look ace when it's all done :D
Hi! Any new updates on this build? :)
Nice! Needs an update. Can someone explain why people run both 1 and 2 wastegates? Surely 1 is just easier and cheaper? Or is two more beneficial despite cost etc?

Better response combined with higher flow. Twin wastegate setups are supposed the spool up a bit quicker, the downside being added cost, weight and complication.

Are you planning to run two then, or just one? I look forward to the videos when you get your car back ;)
Just one :)
Even if I hadn't chanced across a well priced HKS turbo kit, I was always looking for a divided manifold with a single wastegate flange. I'm willing go sacrifice a little performance for a bit of cost saving and a simpler system with fewer components to go wrong :)
Was going to wait until it was all done before updating again! It's being mapped on the 30th for me to collect on the first weekend of Feb (assuming everything's okay!) - can't wait.
That, and I haven't got any more pictures yet and build threads are worthless without them ;)
Few more pictures :D

Got a video of first startup, however...
Bloody weather has meant postponing the road mapping though, by a few weeks :( She sounds lovely in the first video though, can't wait to hear it in the flesh!
thought you'd crashed this? is it still around then?
I thought the same Ric but was wrong, it's T14PPA who unfortunately crashed his.
Oh, could have swore it was this car! my bad!
I've had a few close calls but never crashed it! ;)
Car has now been mapped with some boost, sounds like we're getting a really good spool - exactly what I was aiming for! :D
Few more pictures, although these are about a week or two old now:

Car is back home for some bedding in miles now :)
We're getting on boost at 2800RPM - an absolutely fantastic result as far as I'm concerned. Plenty of pictures to come after I've given the car a wash, had some fantastic workmanship with all of the pipework (and now want to show it off ;))

Random car park picture. Still doing my running in miles, ready for a proper map on the 12th/13th to see what she can really do. Can't wait :D
Currently limited to .6 bar boost and 4,500 RPM, boost comes on very early and feels great so far.
Congratulations on getting everything bolted together and drivable.
Look forward to the forthcoming updates once mapped up.
Beautiful supra Tsia :cool: jealous!
Why is the side repeater just hanging off the side?
Car is looking good though :) Still remember when Ben had this car.

I only realised this once I was home! The clip holds, but barely. It's on the list of 'bits that need replacing' :D
And yeah, I was reading up through his posts for a bit more history on the car a while ago. Always good to know that its been well cared for.
Decided to give the spark cover a lick of paint and the dash panels a refresh with some rubberised black, going for the 'OEM+' look today, off for a proper map tomorrow now that the engine is worn in, then onwards to giving the engine bay a bit of bling, as well as starting the hunt for a new steering wheel.
Oh and that indicator has been fixed ;)

Few things that we needed to sort out before it could get a proper boost map - all done and back home on the drive again. An absolute pleasure to drive, feels like a bloody rocket - and sounds like one too on full chat. Really, really happy with the result :D

Next up is getting that autobox to hold a bit more torque... ;)

Sounds good, but dont tell half the story! What were the figures?

Hasn't been on a proper dyno yet, but the ECU software said around 470 to the wheels with 1.2 bar of boost. Planning on sorting out the gearbox and then turning the boost up a bit higher.

Have you got gearbox coolers?

Two, but I've cleared out the bank for this one. Both myself, the mapper and engine builder were comfortable leaving it there rather than risking an early retirement for the current box. :)
I know it divides opinions, but it has been a long time coming...

Will I be seeing this at an iseries sometime?!
Haha quite possibly! Some colleagues and I were thinking about doing a summer one this year :)

Further polishing needed on it, but figured I'd test fit it quickly :D

Sprayed the strut brace to 'fit in' with the rest of the engine bay a bit more (and yes I put the suspension bolts back on before driving it again!)
I think the next few weeks are going to be spent doing 'odds and ends' around the car like this to tidy it up.
Whilst I'm at it, I've had to unplug the traction control motor so that I don't have a speed limiter kicking in. Does anybody know what pins I need to bridge in order to stop the light from flashing on my dashboard, or if I should simply remove the bulb?
It's been a long time since I've updated this, so...
Since the last post, the car developed a misfire problem, had that sorted out, all fresh coil packs put in etc. as well as a little tinkering with the map. It now runs beautifully, starts first time and it's like a bloody rocket - ideal! At least, it was until the gearbox decided to quit its job (Stock autobox with two fairly hefty coolers). So, I sourced another TT gearbox and had it shimmed up by DavidP - in the process gaining both a much better cared for gearbox and some solid advice on caring for it going forwards. Plenty of lessons learned that day. Anyway, the gearbox will be replaced on Friday this week to get me back out again.
Having the car 'off the road' does have its benefits though - it meant that I could finally tackle the horrible, flaking-off, gold painted calipers from one of the previous owners.

Wahey, one task ticked off, ten million more to go! :) Next up is getting the wheels tidied up, as you can probably see from the pictures above, they're not in the best shape. Thankfully, during the downtime diagnosing the misfire, we also had chance to properly fix a small spot of creeping rust around the windscreen. So, the current hit list, as it stands:
• Fit gearbox temperature gauge
• Fit gearbox thermostat
• Refurbish wheels
• Remove redundant electrical devices from inside the car (i.e. the front spoiler controller, traction control switch etc.)
• Replace heater matrix pipe at back of engine bay
• Get the car on the dyno for some actual numbers!
