Who is going to turbo/supercharge there 2.7l?

I can ask, but in all honesty, it would be quicker for me to get you a trace of the flange to transfer over to a fresh plate and go from there.


As you can see, the gaskets basically Orings. Should be a nice, positive seal, just be weary of how you tighten the manifold down to avoid squeezing the rubber put of its home

 

I looked up a comparison a while back and, based on what I found, the engines are very similar. I got the impression Toyota is very much "if it ain't broke don't fix it" with the 2.7s.

 

Yeah, @MrCrowntown said that the 2tr timing cover is thicker than the 2/3rz one but it won't be that much. You wouldn't have to redo the nose drive runner. An aluminum spacer for the pulley should do the trick. I think the only fab work required is replacing the 2/3rz flange with one that fits the 2tr. That would have to be custom made... or not?

 

Yes, some accurate measurements and orientation would be OUTSTANDING

 

I second this! But even better if I can just buy that flange and weld it on and be done with it

 

Im asking about the flanges now, since its morning there

EDIT: might be able to get them sent

 

Woot!

 

It's in the Camry XSE with 300hp and also in the RC350 with 300hp.

So it's in the sporty version of the Camry and dedicated touring sports car. It's a sports car engine.

 

It's chill dude, this thread isn't intended to "knock" your engine (plenty threads already do that), it's about boosting the 4banger

 

Yeah, but if you're looking for BIG BOOST you're changing pistons anyways so that's not as big of an issue, you just gonna buy low comp pistons anyways.

For those of us looking for a bolt-on solution it does make things harder though.

I've looked at the URD supercharger and the OZ boost turbo setup... I don't like that the URD kit requires a move to 93 octane plus a lot of weird caveats like "don't hit full boost on under a quarter tank" ... could be CYA, could be that they have exceeded sold, safe design parameters in pursuit of bigger numbers.

Supposedly the OZboost turbo kit runs at 5-6PSI and requires no ECM reprogramming, which is maybe a little suspect to me...

I've already got LCE headers and there is no way in hell I am trading those beautiful bastards for a mystery meat turbo manifold, so a supercharger is in my future if I ever do decide to go forced induction.

My dream setup would be a low boost superchager tuned by OV tuning.
Runs on 87 with a meaty powerband that maybe only puts out the same peak numbers as the V6, but feels like it has way more grunt all around.

 

LCE is finishing up their production turbo kit for the 2tr soon.

 

How long should I wait for LCE before I pull the trigger on the OZ boost kit?

 

Probably within a couple months. I get the prototype in a couple weeks, then its testing time before it's sold to market.

 

How much do you anticipate they'll sell the kit for?

 

Probably comperable to their 3rz pro kit, with maybe just a little bit more, because of the newness of the kit and needing to recoop initial production costs.

Their 3rz kit is 2500 bucks

 

Pipe dream. You can't run 87 octane with any sort of boost and especially not if you want to get near the 4.0 V6 power.
Or can you??!?

 

I said "maybe" implying that it would be an absolute best case scenario, I know it's a tall order.

My guess would be that you could run about 5-7 PSI of boost on 87 octane with few problems. That's really low boost all things considered.
Just ballparking estimates, 5-7 PSI should net you something like 215-230 HP (making a lot of broad assumptions about airflow and tuning and AFRs, do not take this as gospel) so yeah, you'd still be about 50 HP shy but have bridged half the power gap.

2.7L with appropriate tuning and boost, 1 bar (~14.7 PSI) should have you upward of 300 HP.

I can't find it right now but there's some madman in Thailand (I think) with a 2TR running E85 and making something eye-watering like 700 HP.

 

Not sure why you keep saying 87 and boost go together. Hope nobody listens to that. Unless they want theirs trucks sounding like a paint shaker full of nails

 

I don't know why you think it's impossible to tune for 87 on boost... many, many cars out there run 87 with far more boost.

Example: almost every Ecoboost motor that Ford makes (That I know of) runs on 87. From the 1.0 Fiesta turbo to the V6 in the F150, all take regular with no issue. I haven't looked up their CRs so I'm gonna take a wild guess and say they're probably lower than 10.5:1, but tuning has advanced to the point that we can have some pretty wide ranges of timing advance/retard and injector duty cycle to handle 87 vs 91 or 93.

Sure you are leaving timing (and power) on the table to prevent preignition, but it's not some zany fucking idea.

TL;DR if you're not touched in the head you can probably tune out a low boost 87 map just fine. Especially on a truck with a 5500 RPM redline.

 

Aren't those FORD ( Found On Road Dead) engines intercooled?

Edit: but you might be on to something. I had never heard of it but my buddy who has the ecoboost says he runs 87 no pinging but the turbo fiesta needs premium just like the subie STI and that's with an intercooler...
