[Mk2] [Turbo] Stock Rev2 3SGTE: 487.3bhp & 364.6lbft, 2.2 bar & 8100RPM

Too much mate.. 2.1 bar on a 3071.

500 on a 3071? Impressive- I'm guessing on a 1.06AR exhaust housing?

Ok, any links?

Too much mate = dreamer.

[gavinda]

his car is on the celica forums and i think he ran a low 11sec 1/4 from what i remember so ~500 ish in a heavy st185 is prob about right

[Turbonoz]

A gold one?

Would be good to get some more info, if he's built it surely he knows the spec of the engine

[Turbonoz]

double post

Am i correct in thinking the rev3 oil pump has a higher flow rate than the rev2? i believe the pump itself is the same but the increased flow is down to a smaller pulley and hence the reason for a shorter cam belt on the rev3?

Yes that is right.

Great thread, I was going to go down a similar devil be damned tuning route when I still planned on going 3SGTE, as in before I fell in love with v8's. Im however curious about the oil specification - why run 15w50 as I understand it the higher the numbers the thicker the oil, the more likely to frothing at higher RPM.

I run that grade of oil in my GTiR & MR2 as it has proven to be successful at maintaining good oil pressure at higher temps in the older engines I deal with that are used mostly in anger. I'm moving to the HKS range of performance oils due to feedback for the products (not the name )

intresting read would like to know how long it lasts keep up the good work p.s got a rev2 running 302bhp not mapped was thinking of getting it done what would you charge dont want anything to fancy 350bhp would be perfic pm me if you would like to quote me

Convert it to a Rev3 ECU and you will have your 350 hp no mapping needed.

thanks bob

Sketchmyster:
Converting to a Rev 3 ECU won't get you 350bhp by itself, but it can be done. You would need to monitor fuelling & knock levels religiously. By the time you've paid for the conversion, AFR gauge, wideband sensor & knock display (these aren't required to get the power, but essential to monitor what's happening) you still have a non-mappable ECU, so there are much better (i.e. reliable & customisable) & cheaper options, but it all depends on budget & overall aims for the car.

[synXero]

Can I pick your brains on two issues Turbonoz?

Camshafts
There's a fellow Beams 3S-GE redtop owner who claims to have found a source for drop-in camshafts. They are specced as: "inlet 270 and 11.5 lift. outlet 264 and 11.05 lift".

1] would you expect that the beams ECU would cope with these?
2] would you need supporting changes, like valve springs etc in your estimation?

Superchargers
Another fellow has a supercharger 'kit' that he has essentially pooled together. Composing of:
Rotrex c30-94; SC Bracket to fit Beams; Air inlet pipe; Intercooler; Pipe exit from inter cooler; Oil reservoir; Engine mount to hold intercooler; Belt tensioner and pulley. No blow-off valve, but flange for blow-off valve in exit pipe.

He made a suggestion that "Not 100% sure but i reckon with low boost the OEM ECU will be fine and you should be 250 rwhp". Now he is definitely not the type to try and deceive and isn't making false claims, but it got me wondering. Do you think the stock ECU would handle a few PSI?



Together, on stock internals and stock ECU, this lot would undoubtedly be carnage. I just fancied seeing what you thought!

A stock ECU will take care of all of that, far better than any after market one.
You have the CT20B turbo and lower compression.
Steve has been running the stock ECU with 278 cams and T3/4 turbo for 2 years now with no problems, it will be ready for the first race soon, I am sure he will give you a blast in it.

[sketchmyster]

thats intresting good to have the orical down the road lol and steve better take me for a spin lol

Really? The stock knock control isn't the best ever, hence the endless threads on here for cracked ringlands.

[bobhatton]

The knock control is great, it is working most of the time with stock boost.
It can only do so much when the boost it turned up.

Any engine running more than stock boost needs a lower compression or higher octane fuel.

Base timing can be set to say 6 to 8 deg to help but is the wrong way to do it.

sorry, but that is BS advice.
