Small update. What is this

Fingers crossed the real thing will look similar to the render

We're nearing fabrication of the diffuser/underbody and aluminum sideskirts. Thought I'd give a shot at a quick and dirty photoshop render so I can show them how I want it to come out. Hopefully we can get it to look proper

Thanks @maddox710 @pick1

Thanks guys I'm glad that you like the build

Thanks Amjad! I think I posted this already above but this is a video of my latest run: This one is my brother's 35-car grid race action starting from pole (they do 1 warm up lap and a rolling start because of the sheer number of cars)

I've just got a hold of photos from last week's circuit leg. Sorry for the quality they didn't really get good pics of the car in action, but well this is better than nothing GT Radial team cars arriving on the track (which included our little turbo hatch) Running with the rest of the pack Going wide! Go home starlet! You drunk!

Yep! It worked well for a stop gap solution. The end goal is to go forged if we can get enough sponsors so for now we keep the try to keep a more conservative tune. We're not running drag anyway and the car is super light so right now the power we're generating is more than enough for our needs

@Starbo Moorley at the last dyno run with the old tired TD04L @ .8 bar we were making 155 hp / 127 ft lbs at the wheels . We haven't had the chance to get her dynoed recently because we're in the middle of a season. We upped the boost to about 1 bar and changed tuners we're feeling a definite increase but its all butt feel as of now. Maybe after the season we'll get to dyno it again for the next one I'll post the numbers here.

So I just wanted to post some pics of the old rebuild done roughly 2 years ago when we decided to go with the vitara pistons to replace the broken 4efte ones just for everyone's reference This is what happened to the stock 4EFTE piston: The vitara/esteem (G16B) piston I actually bought them off a friend who used them on his 5EFTE build but suddenly had the budget to go forged so he didn't have any use for them anymore. But they also worked great for him. He bought brand new and didn't even put 1000km on them. Again your mileage may vary and it will depend a lot on the skill of your machinist/machine shop. You can see them here re-pinned to 5E conrods. To the left are the old 4EFTE piston+rod. Since I was still going to be using my 4E block we had to have them re-pinned to my 4EFTE rods. We opted to use a metal head gasket because the compression is much lower now due to the dished design of the vitara pistons (standard 4EFTE pistons have flat tops) Vitara pistons are in the rebored/honed block Putting it all together (this one still had the stock manifold and old ct9/ct12 hybrid turbo i had) This is how low the compression ratio becomes after using vitara pistons Anyway that's about it for the vitara piston rebuild 1 dyno session and 2 circuit seasons later she's still going strong and now at 1 bar boost.

Thanks guys I'll post pics of the car in action soon

Thanks @H_D

Well that's better than zero options I guess...

That's awesome to hear. At least I don't have to throw away my block after 75mm. Who provides 75.5mm pistons for the 4E block?

@shorty thanks glad I could help its never too late to turn a botched build around you just need some patience. Also, wow that's new to me I always thought that 75mm was the biggest you can go with our block. How does she run on 75.5mm pistons?

@Idrees its never to late to take it to the track Thanks for the compliment!

Thanks @lew777

I don't know about whether or not it can really run higher boost levels, because I'm still just at 1 bar and frankly on a circuit/time attack car you don't need that much power. But the only peculiar thing I noticed is that even without changing the mapping in eManage our AFRs always seem to be on the richer side no matter how much we increase the boost. It was true when we upped it to .8 bar and we noticed the same thing when we went to 1 bar. Maybe its the rebore. I'm not sure but whatever it is – it does give us that extra margin for boost.

@Shorty it is great fun! Nothing like meeting up with your friends once a month to compete in local grassroots motorsports events I think that lip was a custom one. Came from a Toyota (Corolla) Altis retrofitted to my car. @Amjad During a routine piston ring replacement way back when the car was new to me we discovered that I had 2 cracked piston lands. Unfortunately there were no OEM 4EFTE pistons available at the time and to order one would take months. Since this was my only car at the time I couldn't afford to do that. We found out that other shops locally were secretly using "vitara" g16b pistons – much like you would in a SOHC honda build as a cheap upgrade to 4EFTEs. Their reasoning behind it is that it allows them to lower the compression even more than the standard one because it has a dished top (vs the d15b's slightly domed top and in our case 4EFTE's flat top) , which in turn allows them to run more boost (with proper fuel support of course). The actual vitara pistons are 1mm bigger at 75mm vs the stock 4EFTE pistons so you would need to rebore. To be honest I wouldn't suggest this to anyone unless they really have no choice and if you do you must go to a very reputable machine shop because you will be at the limit of the engine's clearances to fit Vitara pistons. But so far my engine has been running great since then no issues from the block at all.

Thanks!

Fixed the images

Here she is now. Pictures taken at the most recent leg of Circuit Showdown (the time attack/grid racing event we joined): Also upped the boost to 1 bar now With her other hot sister - my EK9: Boost or Revs? I grabbed another fourth place in my time attack class which brings my overall standing to 2nd Here's a video of my latest run: She's still a work in progress. A few things we need to do is to replace the shitty temp dashboard we have with a properly fabricated racing dashboard. I'm also thinking of some aero a proper front diffuser/underpanel because she does get "floaty" at high speedsbecause of her being very lightweight. Also we need a b-pillar bar to properly mount the 4 point harness into and modify the rear axle to get some adjustable camber. But here are her specs as of right now: SPECS: 1990 Toyota Starlet GT Turbo - Quad lamp conversion 1.3L 4EFTE Engine Block Rebored to 75mm Suzuki G16B Pistons TD04L @ 1 bar boost (14.5psi) 5EFHE ACIS intake (dual runners) C56 5-speed transmission OEM LSD Goodridge Steel Braided Brakelines Runstop Uprated Drilled Front Rotors Ferodo Brakepads Emanage Blue Greddy 3 Bar Map Controller Apexi AVCR Boost Controller Custom temp triggered automatic radiator water sprayer Custom manual intercooler/oil cooler water sprayer Prosport Wideband AFR gauge Prosport Oil pressure gauge Sparco Carbon Fiber Bucket Seat Personal Steering Wheel Custom oil/water temp gauge Custom surge tank Blitz SuperSound Blow off valve Bar & Plate Front mount intercooler Custom designed exhaust manifold Custom straight through exhaust Custom 6 point cage BC Racing Coilovers Cusco Front and Rear strut bars Cusco Adjustable Panhard rod Custom rear sway bar Fully stripped interior 15" Rota Grid 2 195x50 R15 Champiro SX1

Reworked piping Surge Tank TADA! Off to the races we go! By the second leg we actually had a win. I went from 7th to 4th in my time attack class. My brother bagged a pole position and secured a win for 2nd place in a highly contested 35 car grid race! POLE! Winning was awesome. Now that the car felt very competitive - it was time to do something about its looks. Next up: Repaint! I wanted to change the colour from red to something else because there were already quite a number of red race cars in the event. I opted for a dark shade of gunmetal for the outside, silver for the cabin and blue for the cage. Continued...

A little over a year ago I was able to acquire as my first car a pristine red EP82. The red hatch in her last pristine condition. Unfortunately due to a stupid decision the car ended up on the receiving end of a botched mod job to make it into a "show car". The experience was so painful I've deleted all photos of it. I wanted to forget about the car so bad that I ended up buying a very fresh EK9 Civic TypeR. The rebound... But of course you never really get over your first car. Coincidentally I was toying the idea of entering the local circuit racing/time attack scene along with my brother. So we decided to just have the car rebuilt as a full race car. Fortunately there were some parts that was purchased for the previous botched mod job that we were able to use for our purpose. So we found a shop and started the transformation. BC Racing Coilovers Prosport AFR Gauge + Wideband O2 Sensor Kit, Prosport Oil Pressure Gauge Apexi AVCR Electronic Boost Controller Cusco front and rear strut bars Blitz Super Sound Blow Off Valve 5EFHE ACIS Intake Manifold / Bar & Plate FMIC 2nd Hand TD04L eManage Blue We stripped the car down, had a custom rollcage built, had all the parts above installed and mapped. Since this was going to be a circuit car and the internals are not yet forged the tuner opted for a very conservative .8 bar. Squeezed out 155whp which was ok. We had fun during our first season racing unfortunately we were far from competitive and the car was not reliable at all. Suffice to say I was very disappointed with the support from our tuner. Anyway at least I saw that there was hope for the car but we needed to switch to a different shop/tuner. So we did. Dropping her off the new shop for the next race season Right away a lot of shit that the previous tuner has done to the car was fixed. Reliability was prioritized - we had to get the car to be reliable before the first race. Long story short we became competitive and my brother was even able to push to go 2 classes beyond his previous class. I ranked 7th in my bracket (where I usually would be 20th). There was hope! Working out the kinks. Stripping out the harness Reworked simplified racing engine harness After the 1st race There is hope Next up we needed a few quick upgrades to be able to push harder for the next race. So we got a fresher (brand new) TD04L to replace the used one and basically rework all the turbo piping and improve the cooling by installing automatic and manual water sprayers for the FMIC/radiator and oil cooler.
