Celica Forums General Discussion Exterior Does anyone know anything about brashboy 2.0L upgrade?

I am torn, dont know what to do.
On one hand I could get Nitrous system.

On the other I could get 2.0L upgrade.

The nitrous I know what I will get

The 2.0L upgrade nothing.

But here are my thoughts, I can go displacement upgrade and in the process strengthen my engine,(ofcourse I would also get the stronger valves) so that later if I did nitrous I would have an engine that could handle it.

The only problem is that I don't know anything about what kind of hp gains can be had from moving displacement to 2.0L.

I need some input.

yea i tried to get some info on this last week...no one new anything

I think it's about the same as Trials 2.0l kit. They claim 220 hp with 105 japanese octane. So you might get a 15-20 gain on 91 octane. I'm not 100% possitive, but it should add a good chunk of hp.

hmm, i have no clue...
but for me id get a 2.0L upgrade

i dont like nitros in any way...

Some of the mechanics at work say there should be about 18% gain.
If that is true I would be pushin 250 hp and that would be worth it.

I dunno about 250hp 'cuz Trial is a realiable tuner & they claim 220 with 105 octane. But it would still be worth it 'cuz you plan to improve the internals.

Can you post a link for the trial version?

Well with the mods I currently have an additional 18% would bring me there.

See trial claims a 22.5% increase that would be cool.
That would bring me close to 250hp.

After the kit you get about 220 hp and 20 kg of torque. on Japanese high octane gas (105).
The Engine will hold up to 8,000 RPM. The valves are thought to be the weak point of this engine.
The stock valves are generally ok up to 7,000 rpm, but if you plan on going over that,
a valve kit is recommended. The valves used on the Trial Shop Car are $2434.95.
Stock valve springs are fine.

so there is no Lift if we do the 3ZZ upgrade ?

Right thats about 22.5% over the stock 180 hp am I wrong here?

Yeah thats a good question?

Thats some sketchy engine math. Its like adding up Hp from each seperate bolt on and getting a final number. 10 Hp from intake + 10 hp from exhaust+ 10hp from headers does not necessairly mean you get 30 more hp. All that stuff works together and some may cancel each other out while others get even better gains. Usually however its the former. So this means that just because the trial got 220 which is 22.5% more than stock it does not mean you will necessairly see a 22.5 increase in yours. Also that would mean you have like 210 right now. Which you very well mght have but unless you dyno you never really know where you are.

I say do it and dyno it...upgrade your internals also to make it worth while..

Does the trial kit increase the bore or just the stroke. I wonder what the increased piston speed of a stroker kit would do to long term reliability of the engine?

Yes your right and I will be going to the dyno next week if the weather stays good.

I think its just the stroke which also increases compression I think?

I will post the dyno results then.

There is a superstreet magazine with a celica that is a 1.9lt engine and after some engine parts is at about 330 horses

hey do you need to bored the engine out wit the stroker kit or can you just get the strker kit n put it in replacin the stock internals

would you get more HP if you bored the engine and add the stroker kit??
