185 3S-GTE engine + ecu questions

[Wildsupra]

Hmm yeah i might high flow the turbo straight up, as i plan on doing that for sure later, i was hoping to run around 15psi before i get serious with it.
I like the idea of the Plug and Play wolf.
Classique71 could you give me some more info regarding the wolf you used. As in where would i get one? and at what cost, also is it version 4? does it come base mapped etc etc. Very keen on it. Especially as its plug and play.

I would like to upgrade cooler, but am very limited with what i can do, a front mount is certainly out of the question for the AW11. Once the car is engineered i might get cheeky and go the roof mount

dood, Highflow is pretty exxy,
if i was you, i would sell the current CT26 and spend the extra money on a GT28 especially if you are going aftermarket ECU...

Or GT30R or bigger after eng. cert. the GT4 ran 17 psi regularly on an unopened 2nd. gen. 3SGTE rebuilt it at 265K because of a main bearing knock on start up every thing else was not bad slight to moderate wear HG was good , tuff motors pushed it hard & now will push it a bit harder

[Classique71]

the cost for mine is irrelevant as it was a wolf mule , costs were obviously lower than normal retail - they retailed at about 1395 without a handset i believe off wolfs webpage

how many kms on the engine? Thats probably the biggest factor on the boost levels you can run.

On a fresh engine, you could run 12-14psi all day. But on an old worn engine, much more than ~12psi is going to eventually spit the headgasket. Thats what happened to Lance's car, and mine at the time wasn't far behind.

I'd put the money towards a light rebuild of the motor rather than a high flowed turbo. No need to go silly, just a freshen up with new MHG and some ARP studs. Maybe check the mains/bigends and replace them with a crank grind if required.

Then maybe pick up a second hand "CT20B" in good nick for $500 and run about 15psi.

The Wolf is OK, i didn't mind it, but for a mild motor, I'd probably just mod the fuelling/igntion with an emanage or similar. If you have grand plans of 220Kw+, then go the Wolf now.

[Classique71]

Agreed with spectral

the wolf is capable of it - and i REALLY would have liked to have tested its boundry's on a 205 , but i still have yet to hear a reply re further group Buys or 205 support for group A's

Not holding my breath on it im afraid - Power FC is a more likely candidate

As for a Ct20B - i have a " second hand " one available ( ahem ) now ..

[Wildsupra]

Cheers for all the info again guys, much appreciated.

The motor has done 114,000k's
Im not keen on opening it up just yet, but if i do then i will simply do the lot, i dont wanna go as far as bearings and crank grind and not do forgies and rods etc at the same time. Once she gets opened up thats it......its on.

The idea of a big turbo conversion is good except...........its all going into an AW11, and for those who arent familiar with the engine bay once a 3S is in there, let me tell you the ct26 sits VERY close to the firewall!!! That was my reason for high flowing the 26 with steel wheels. Surely that would be good for up to around 25psi???

I have an emanage sitting here and also a wolf 3d version 3 (dont think version 3 will cut it though). But i think full management will be needed in the long run anyway. Well as soon as i open the motor anyway

Is the ct20b the same size externally as the 26? and will it bolt straight to my manifold and run the same custom dump pipe i have now? and what boost are they good for in standard form?

If the wolf is $1395 and plug and play i will prolly just go down that road.

Its all very exciting Looking forward to this one

The ct20b is the same external size as the CT26, yep. It bolts on, which is why its a popular choice for those seeking another +50Hp or so that the CT26 finds its limits at. From memory, Lance did a mid-13 pass with that combo.

I believe one bolt is different on the dump pipe flange, but you just leave it out and it seals up just fine.

I'd use the emange for now personally. The Wolf comes with a base map, but it will stil cost a fair bit in dyno time to get it well sorted. The emanage is just adjusting existing settings, so it would require fewer dyno pulls in theory.

Use the Wolf when you open up the engine and start going for 300HP+.

[Wildsupra]

Well the CT20 sounds like a good iniatial upgrade then.
I've already run a 13.9 with the 165 on 8psi that is currently in the car, i would hope to be able to run a 12sec 1/4 of some description with the 185 motor on about 12psi and obviosuly quicker on 15psi. ideally a mid 12 on 15psi would make my day without having to open motor, and i'd assume (pending a A/F dyno reading) that i would be safe to use a fuel cut defender and run 15psi on stock management??

Classique can you please PM me how much you are chasing for your ct20 and the condition of it also.

Cheers
Matty

[spectral]

no real point going much past 12psi on stock management, as the ECU only has mappings up to 12. So past that it just dumps as much fuel as possible into the motor, so your AFRs will drop and you won't make much more power.. just a lot of heat

[Wildsupra]

hmm i didnt realise that....something to consider then.

Maybe wolf straight up anyway then.

Cheers

on my RAV4 I had a CT20b originally from the 205 front-cut, but when I later found out that this turbo was rooted I got a CT26 hi-flowed and stuffed it in the CT20b shell. The comp wheel was 56mm so the shell had to be bored out another 10k" for a snugg-fit. Only thing I disliked about a hi-flowed CT26 was the spool-up, not a shade on what the CT20b was when we trialled that... like it boosted off the mark and didn't wanna stop. Had it not been leaking oil and pissing out white smoke on boost, I would have stayed with that, but alas.

I wanted to get the CT20b rebuilt as-was, but they said that the parts were too hard to find for it, and I was better going with a CT26 instead. In hindsight I probably should have gone with a T28...

[Wildsupra]

How much bigger is a T28 than a ct26? any idea? and wot is involved in fitting it to standard manifold......or soes any1 know of an aftermarket manifold that keeps the turbo as close or closer to the engine as the original one?
If i get the turbo closer to the motor it would make room for a bigger one

[Wildsupra]

i must say also that lag is not my friend, i am very happy with the minimal amount of lag the ct26 on the 165 provides. I would rather less lag than more top end power..... i think

if space is the issue & u want to keep a std look u can have built a CT26/GT30 with a Garrett GT30R ball bearing core & wheels in the toyota housings ,mine made 205 4 wheel Kw in the GT4
