ct20b on 2nd gen, whos running this set-up? Options

[95st-celica]

i will be picking up a ct20b for my 2nd gen this weekend, and was curious as to see who else was running the same set-up, as well as what other supporting mods you have, and what kind of numbers you were getting out of it as well.

I think this will really open up and answer a lot of questions about the limits of a basically stock 2nd gen, (for us 2nd gen guys) compared to the stock 3rd gen, with such a simple upgrade as a 20b.

From what i have researched, 290-320WHP should be attainable with simple mods to the 2nd gen.

Myself and lagos are going to see what we can do with each of our set-ups, and post back what we came up with.

I really do think that 300WHP is VERY realistic for the 2nd gen with the ct20b, if not more.

Even with the stock injectors and fuel system of the 2nd gen i dont see a problem, as long as it is being supported with methanol. Larger nozzles and a heavier mix will compensate for the added fuel.

What do you mean when you say "you really shouldnt have much trouble making the same power as a GEN3 STILL on the stock CT20B...up to a certain point."

basically what we are trying to determine is that with the addition if the upgraded turbo off of the 3rd gen(ct20b) that these motors will both put out equal HP numbers. its not like we are going out and putting on a GT2871 and saying YeA WEll we made 400whp with this!!..lol..we want a basically stock, even platform to go off of, and then compare the results once the boost is turned up.

Thanks jim, im looking forward to seeing what we can accomplish as well

Like I said, you wont have any trouble making WHATEVER power goal you have in mind if you are willing to tune on Methanol Injection. Supra guys have tuned for 150+whp OVER what there pump gas tune have allowed them to do by supplementing enough Methanol. So you looking to supplement in 25-50whp isnt going to be a problem. Obviously this comes with its own fair share of risks, but Art knows all about them.

I have said it before, you wont have any trouble making the power the a Stock GEN3 makes STILL on the stock CT20B. Even tho the GEN3 3sgte has a better Intake manifold design, More aggressive cams, etc...you are comparing tuning on "race gas" (thats basically what tuning on methanol is comparable to) vs a stock GEN3 still on the factory ECU. After tuning a few 5s setups, I was quick to realize the power that can be pulled from tuning, it truely blew me away. And with Arts setup, you will have the ability to tune for the methanol, which is big. You will have MUCH better Afr's and more timing advance with Art's setup then you would comparing to say my stock GEN3 dyno's.

For example, if BOTH you and Art were installing these turbos, and planned on running the same amount of methanol injection...Art's numbers would be CONSIDERABLY higher then yours. Now, there would be ABSOLUTELY no difference between Art's setup and yours (same turbo, same generation, same bolt on mods, etc), EXCEPT for the fact Art has the ability to tune for the Meth with his SAFC and you wouldnt.

So the test you are doing I see more of a comparison of the benefits of tuning for Methanol, as compared to the same setup on Stock ECU with no tuning.
