Try moving the shift stick into the neutral position with the car off.

A stock IC is not a good idea. What's going to happen is you are going to kill the nubmer 3 piston especially boosting that high. If you are going to run the car at high levels of boost even 15 pound all the time on the stock inter-cooler I wish your motor good luck. It will not last more than 4 weeks. Trust me I know, I have been down this road.

High boost levels + stock inter-cooler will = blown motor.

I will keep my fingers crossed for you especially when you boost 22-25 PSI on stock internals.

Also it is very hard to attain 270 WHP on stock cams and pump gas. You will not even come close to that on that CT27.

[ursoboostd]

People make over 300 on stock internal all the time. 22 psi on a CT27 would problably be less than 17 psi on a TD06 or a turbo of that size. Right? -Wade-

Don't people usually make about 200-210 on the stock ct26,full exhaust,. IC and 15psi? So your telling me with with my ct27/550/Rom tune I only gained around 20-30 rwhp? Gee I must have really gotten it in the ***! -Wade-

I always say seeing is believeing. You will not make over 240 WHP on stock internals stock cams and a CT27. Please dyno it and show the graph.
Remember this all your modifications that you do are only as good as your internals. Also you are going to need an EMS system. Dont believe the hype about this CT27.

No here is dyno graph for you off my car with 550cc fuel injectors 2.5 exhaust, IC 16 PSI CT26 upgraded and ported and up graded fuel pump and fuel rail. This is reality for you



and whe I upgraded to a gt30 turbo set up and EMS sytem with the 550 fuel rail, IC, exhaust and 19 pounds of boost on pump gas this is the most I got a the safest level. In only lasted me a month. The best way to make power is to make the most power you can make at the lowest boost level as possible. In order to do that you need to build the motor up. Anways here is the graph.



Dont wast your money. If you really want to make some good power get your self a good turbo set up, an EMS and some cams. Cams will help you acheive in getting 300 WHP allot easier. You can leave your block with the stock stuff.

After I had my motor built this is what I make at 9 pounds of boost and 91 octane.

You never ansewered this. Your not really making sense to me. You may have more experience with the MR2 than me, but please quit talking down to me about "Reality". -Wade-

On 93 octane you will be lucky to get to 230-240 WHP especially on stock internals and especailly on the stock cams. You will be very dissapointed when you dyno it. Please post the dyno graphs on the 110 octane and the 93 when you dyno it.

Any CT26 ported or modified wheels or CT27 is not a good turbo to make you big power. Save your money until you can afford a good turbo set up. Like the street brawler or something like that.

Um, your wrong. I have a CT27, ROM tune, 440's and ran 248 rwhp @ 15 psi. That was on the stock intercooler. I expect to hit ~280 rwhp with cam gears, ST205 IC and 17 psi.

Please show me they dyno graph on it, because on a stock inter cooler you will heat soak that thing so quickly like you cant believe. Also what kind of fuel did you use? Also you said cams gears, did you mean cams. Also are you on stock internals. I have done allot of dyno tunning on my car and seen allot of Mr2 on the dyno with the CT27 and upgraded CT26. None of them have came close to those numbers especially on pump gas.

I am not trying to insult you in any way. So I apoligize for the comment, it was meant as trying to open your eyes to help you save some money. I am trying to help you. You are at where I was 2 years ago. I spent allot of money on up grading the CT26 to try to get good power and I have dynoed my car I say about 50-60 times on diffrent parts including on the stock intercooler. Unless you are going to run race fuel all the time dont waste your time with this turbos. You are going to have to run allot of boost on them, not a good way to go. I am telling you my experiences with this turbos and what I have seen on what they can make on diffrent set ups.

The best numbers I have seen on the CT27 is a set up that had this. This is with 110 octane and 22 pound of boost. He made 290 WHP. With pump gas he made 250 WHP and 19 pounds of boost. So on your stock internals It's going to be harder to make this.


550cc fuel injectors
EMS
Fuel rail
upgraded fuel pump
Cams
Cam gears
upgraded inter-cooler
3 inch exhaust
head work
Uorthodox pulley
3 inch down pipe

I will post the dyno graph when I get home. Yes, the stock IC heat soaks fast. I had to wait 10-15 mins between each run with fans blowing in the engine bay. I also have two back to back runs (within 5 min. and you see the loss in power). I will post those graphs as well. Yes, I did mean cam gears and they are not tuned. Stock internals with 264 intake cam only (set to HKS specs). Good old 93 octane.

i made over 240whp with mine and it was heatsoaked from the 2hr drive. 244rwhp@17psi

See you also have cams 264's. So you dont have a complete stock motor. Cams are the best things to have to help you acheive higher HP. What esle do you have?. So what I am trying to say is that he will not see close to those numbers especially on the stock motor, you dont have a complete stock motor, becasue he said he has an all stock motor. Also you are going to need to boost more that 17 to hit 280 WHP especailly on that CT27 becasue ask them to show you the flow chart on it. It can only flow so much pressure becasue of it size. Your are going to need more like 19- 21 PSI on pump gas to even get close to that.

Exactly you used 17 pounds of boost he said he did it on 15 PSi I just cant see it on that turbo because of it's size and the amount of ari flow pressure it makes. Also what mods do you have. Also what kind of fuel did you use. Please post dyno graph.

Here Ricky-b descibes about turbo sizing. This will give you an idea of what that thing can really do. Please read it. Kind of long but very informative.
