sorry my mistake... was his high flowed CT26 not CT20.
here's the figures for his 3 sw20 turbos...
CT26, ~130kw @ 14psi
CT20b, ~160kw @ 16-17psi.
my modified CT26, ~215kw @ 19psi

If my ct20b is only capable of 160kw, there is no point in upgrading the injectors and pump...

not to say that's the MOST you can achieve... but it's wahat his was putting out... the CT20 can get a bit more with that as its still efficient running a little more boost for starters. But yeah you may run into the limit of the stock turbo before the stock fuel system. can anyone remember how many lbs of air the CT20 can flow??? roughly multiply it by 10 and you get your max theoretical horsepower.... ROUGHLY. so a turbo that will flow 55lbs like a GT3076 will support up to ABOUT 550hp.... 3071 is about 45lbs and about 450hp... from memory.

I started with 162.5 in stock
A few more mods later ended up with 211, so yeah not the limit of their capacity.

Mmmm.
Might just chuck it on dyno as is, tune it with emanage ultimate and see how we go.
Possibly standard fuel pump and standard 440c iniectors with ct20.
18-19psi, whatever the tuner is happy with (im happy with 20 for all i care) and whatever it spits out, enjoy it. Sounds like a plan
Quietly hoping for 190kw

i found these old graphs of mine with a CT26 running 14psi. thought i'd post them for reference. 150kw with rich fuelling, an OLD turbo, and the stock exhaust and cat converter in. hope it works this time... AF varied from 12:1 to 11:1

So dump pipe and full exhaust say 10kw. Lean out the map and its maybe possible to achieve 170kw.
Swap turbos to ct20. Boost to 18-19, tune to 12:1. Theoretically, 190-200 should be achievable but only one way to find out.
Funny question but is it a good idea to brinng my garden blower for the side cooler? And maybe another normal fan for intake? As my tuner, Cihan from edge motorworks hasent done too many mr2s. Mmmm

Blower that is used to blow away leafes etc so ambient air.

Probably has. He has done that many cars. Sorry my previous post maybe sounded like he doesnt know what he is doing, which he obviously does for me to be handing over my car.

Just finished tuning it.
Result 191kw at 18psi. Pretty happy, close enough is good enough.
Must add we had issues on the dyno, the intercoooler quickly got heat soaked and ha troubles with it but other than that, Cihan from Edge motorworks did his magic to give me best results as possible. Tune is spot on and I highly recommend him, and I've used many tuners previously and in my opinion, Cihan is best.
Also worth mentioning, on the dyno, my knock sensor failed. Cihan picked it straight away.
