Tubbys SW

[mr2 Tubby]

Got my gen2 SW20 turbo 2 years. It lasted a year and a half before the headgasket gave up. Last 6 months I've been rebuilding the engine and tidying the engine bay up, it's now wire tucked and much tidier than before. Outside paintwork not the best, but that's next on the list.

That's one clean engine bay you have there
looks great with the wire tuck.

Its not often i see a 3SGTE engine bay i like the look of, but damn that thing looks mint.

Should go nicely, just needs a bigger turbo

I agree, the rebuilds bled me dry tho and the next power upgrades a big expensive slap in the face . Main goals a good responsive powerband with little lag thats good for track racing. Im pretty happy

You will find the CT26 should get you to 200Kw if it's done right along with the rest of the build. I still like the way it spools with no lag and the power is delivery is extreemly smooth and predictable on the track.

very clean. i remember when mine looked clean too. I wish theyd stay that way. I spose it would if i didnt take it out of the garage.
Lots of work done internally which is good. that should last you a good while, that engine.

[Dell'orto]

Very clean. Still running stock ECU?

[mr2 Tubby]

For now, upgraded ecu comes into the big expensive slap in the face category

You won't need it for 190-200Kw, just up your base fuel pressure a few psi and put the rest of the money into doing a first class job on the rebuild and run 18psi on the CT26.

Keen to know what you finally get out of it after the short run in period and then the Dyno.

there has never been a ct26 even modified that can get to 200kw on stock fueling .. please stop posting missinformation

I think even CT27s from ATS which is a fully worked CT26 still struggles to break the 190 rwkw mark.

My Ct20b managed 190 rwkw at 18psi on stock ECU, there was nothing else left in it without going to aftermarket ECU and even then with perfect AFR tuning 200-210rwkw would have been the maximum on 540cc injectors and 20 psi of boost.

Correct me if im wrong but weren't you using 96 octane?
There are plenty of ct26 upgrades in the states running 193kW at the wheels, thats without cam timing or a fresh engine. Retarding the exhaust cam has showed quite often gains of up to 15hp (11kW).
CT27's have been pushed to 220kW in some cases and 240kW on race gas. Alot of psi but it's been done
The limits of the factory injectors is about 205kW. Im guessing you mean 440cc injectors cause 540cc would max out well over 300hp.
Im just hoping to hit 200 or as close to it as possible. Above 190 is good.

[vvega]

well i could well be wrong .. i just remeber a fellow many moons ago that got a steve merch ct26 .... and was highly dissapointed when speedtech couldnt get it over 180kw with a v5 link
with stock management .. i prolly wouldnt run 19 psi without race gas ... it runs quite advanced on the stock ecu .. about 19-20 degress of advance if memory serves me correctly at anything over 14 psi .. ...... you could just back off your base timming to compensate ?

It's worth a try, to many people chuck the CT26 in the bin before they even start to get the rest of the set-up right, it's not the weakest link in getting close to 200Kw if you modify it right and are staying with the stock ECU anyway. I have got to 170Kw without even trying, unopened engine at 210,000Km, stock intake, stock IC, stock exhaust, stock ECU and 15psi but I only run 98 fuel.

if i remeber rightly your kw rating is calculated to the flywheel isnt it carl

i do remeber you saying you saying something about using the dyno to measure the gearbox loss
