I just dyno'd my MR2

[Need2Speed]

Hey guys i just put my mr2 on the DYNO. The results on the DYNO were 261hp at the wheels with 296 pounds of torque at 5k rpms. I want to get the car into the 300 hp zone. What should I do?? I swapped in a jdm motor in my MR2 and I still have the NA gauges is that a big problem or should I try to find the JDM or US gauge pod?? what do you guys think?

[scarecrowX]

what do you have done to it thus far?

Bigger Turbo.

I agree, preferrably BALL BEARING!!!!!

I just did the whole exhaust system and Intake system. I am also pushing at like 18 lbs. of boost..

[MR2Driver]

Wow, that helps? Whole exhaust system? Do you have any cats? Downpipe?

Either way, you might wanna look into some intercooling

[Need2Speed]

Im running 3 inches from the headers down
with cats...
what kind of intercooler??
how much??

[HondaChili]

hmm 18 psi is alot for the car. If you only have an intake exhaust in your car, id say you might be hurting it with 18 psi. Plus my car in first and second gear cant spool above 10psi at redline anyways( i dun know if its just my car) , so get a ball bearing and you can spool a good amount on first gear.

wow 18psi is a lot from what i've been reading

[JekylandHyde]

HondaChili, you still have the factory turbocharger (Ct-26) which can not make ful lboost to redline ... it general falls off after 5500 rpms.

Depending on which JDM motor Need2Speed is using, they may have the CT20b unit which will pull till redline.

Boost is relative depending on which turbo you are using.
18 psi is a lot on the CT26 turbo because above 15-16 psi you are making more heat (risking detonation) than you are making additional power. Bascially the measely gains of going from 15 psi to 18 psi on the CT26 is not worth the risk.

If you have the Ct20b (or any other bigger turbo) you will notice significant gains going to 18 psi from 15.

Me personally, I would never go over 15 psi on any turbo on our cars, unless:
*I was using race gase
*I was using water injextion
*I had an upgraded intercooler.

I have all 3 (and more engine safety stuff!) and I regularly push 22 psi of boost out of a much larger T3T4 turbo on my 195,700 mile original unopened engine.

Big boost doesn't kill our engines.
Detonation kills our engines.
Big boost increases the risk of detonating.

If you are wise and careful about upping your boost, you can get away with a lot.

Be careful.

well at 22 psi I hear a knocking sound, and i get constant boost all the way to 6000 rpms. I only put high boost when I am running the quarter mile, but ive noticed that my boost will only spool up to about 18 lbs on the quarter

Which turbo do you have (ct-26 or CT20b)?
Again, if you have the CT-26 there is no benefit in running it past 16 psi, your simply increasing heat (knock/detonation) for negligible gains.

[Need2Speed]

I believe it is the ct26.. When i run the quarter i turn off my boost controler and i Watch the boost gauge and 18 is the highest ive seen it spool up to most of the time I see 15-16 psi on it when i shift close to red line...

[JekylandHyde]

If 18 psi is the max you have seen, then how are you hearing knock at 22 psi?!

If you are on the CT26 and you are revving to redline, you are blowing way past your ideal shift point.
