1zz into gt?

[TheDude]

Allright, i know it sounds odd, but hear me out. I want to turbo the GT, however i realize the dificulty of it due to the high compression and fuel management problems, among other things.The 1zz is of course the better choice for the turbo set up, as some of our members have already done. Now i have the GT model, and its my only car, so i dont want to pull the 2zz and work on it, thus loosing out on my transportationMy idea is to find a 1zz motor, and completly build it up while still driving around the GT. But my question is, will the 1zz and 2zz be a straight in swap? Must i also swap the ecu, or can it be reprogramed?Any input/suggestions will be very helpful

[ragingfish]

Well...you could just buy a junker vibe, build up the engine, then repair any damage in your spare time...and boom, easier then swapping out whole engines...question though: would you be able to use a 6 speed with a 1ZZ?

[dmitri]

ehhh might be tough....im sure u can probly put the 5 speed in...i think the linkage will probly be the same

I wouldn't bother swapping in the 1zz. It's not exactly built for boost. The 1zz compression ratio is still 10:1, most turbo engines are 8:1 or 8.5:1. You can get forged pistons in any compression you want from Wiseco. http://monkeywrenchracing.com/....html Also, XS engineering makes a turbo system for the 2zz engine. It was originally developed for the Celica, but with a few different intercooler pipes it will fit the Vibe/Matrix. It's already been done. Check out Sport Compact Car's website and look at project Matrix. http://www.sportcompactcarweb.com Don't forget that almost every engine part for the 2zz Celica will fit our engines.Personally, I'd like to hit lift with a turbo, but if you are set on dropping in the 1zz:1. Forget about the ECU, it won't be able to handle a turbocharged engine. Stand-alone engine management is your best bet.2. The 6-speed should mate up.Also, if this is your only transportation, you might want to get a beater car. Turbocharging an engine that wasn't designed for boost isn't going to make for a reliable daily driver.Just my thoughts,ND

[QUIKAG]

I second EVERYTHING Nervous Dog said.

[TheDude]

lol right on...i was wondering about the xs-enginnering kit, but i want to hear from a celica that has had if for a while....266hp and 186tq at the wheel is f'n outrageous

[Nervous_Dog]

Dude,Check out the Forced Induction forums on New Celica. (It's my best kept secret) http://www.newcelica.org/ Thanx for the props, QUIKAG

I have to agree with these guys as well. But you may not want the 6-speed in there after you add so much power. I would think that the gear ratios in it would be so low for a higher powered engine that you would have to be shifting gears much too quickly to practically take advantage of the power increase. A 5 speed may do the job better.As for finding a 1zz engine to work on should you still decide to go that route, you would probably be best served to find one out of a Corolla that was rear-ended and totaled. There are sure to be more junked Corolla's out there than Vibes/Matrixes because they have been around much longer and there are a lot more of them made/sold. It's all the same 1zz engine.This turbo kit for the 2zz is interesting... I may have to start looking into this.

[TheDude]

i've been looking deeper into the XS turbo kit, and thanks Nervous_Dog, newcelica helped me out a lot...All im doing now is saving my cash, so i got time to debate over it. I would love to have the XS kit on the 2zz, but i havent heard from anyone thats had it for extended miles, i want to know the reliability of the kit

[FusionVGT]

Dude,Ever consider nitrous oxide? Even a small shot would give you big increase in torque.

[savedbyzero]

Too much money and time for what you would end up with. You could take the time/money and build a pretty fast sleeper of a different model.

[TheDude]

i've considered nos, but i really dont want to use it. I want the power to be there all the time, not limited to short shots

[Stang2Vibe]

I read the project Matrix article on the sportcompactcar website. Be careful, they broke a piston after that kit was installed. And this is by no means a plug and play thing. There is a lot of tinkering with the parts you are adding on to make everything work. It sounded like a pretty difficult job to me.

[Nervous_Dog]

Stang2Vibe: The reason for all the tinkering was because the kit was still in development when SCC wrote the article. Everything has been finalized and the tinker factor has been almost completely eliminated.Also, they had shipped the car to Florida for a Spring Break car show and then had it shipped back to California afterwards. They think the shows promoters were driving the car around and didn't use premium fuel in it. This would have caused the piston failure.

[TheDude]

yeah, project matrix was like 6 months ago or so, the kit has only rescently been completed...It shouldnt be too dificult in the least but, just finding a mechanic i can trust

[savedbyzero]

still a scarey thing to be doing with 11.5 to 1 compression ratio on stock internals...boom! clank.clank.If you wanted to do it right, you can get all new internals over at http://monkeywrenchracing.com/toyota.html wiseco pistons, crower rods, the whole shi-bang!

[Lancer]

Use the money from the engine swap and get a stroker kit that would lower your compression ratio and be way stronger then stock. Then turbo it! That's what I would do if I had a GT and want to DOMINATE!

[DopeVibeGT]

Ok, heres my input.Why would you want to do that? Even if you turbo a 1zz, it wont be as fast as a GT. A supercharged 1zz is slower than a stock GT, 0-60 in 8.3 seconds. And NO, I'm not bashing the 1zz, just trying to figure out why you would want to swap like that. Unless you just want to be able to say "I have a turbo under the hood".

[drunkenmaxx]

from what i have read, the SC'ed 1zz outperforms the 2zz in many aspects. ie-low end torque

[Nervous_Dog]

Yes, they have more low-end torque but most of the time, if you are racing, you are up near redline. A supercharged auto won't beat a GT in the real world. A supercharged 5-speed might keep up, but the GT doesn't have to shift as often with the higher redline. I can do 60 in second gear in my GT, the 5-speed needs to be in 3rd. So I can spend more time on the throttle and less time shifting.Not bashing but I think 1zz owners got screwed on the supercharger deal.

[drunkenmaxx]

yeah, not to mention us AWD's or manual's! it is too pricey/pain in the (removed). if only the awd had a 2zz... someday, when i own GM...

A turbo 1ZZ not as fast as a NA 2ZZ? Are you crazy! There's guys putting down 200+ at the wheels with turbo 1ZZ! Go look over at matrixowners and even at our very own member, Fualtline! Better yet, go find them on the street with your GT!

[TheDude]

lol, this is turning into a 1zz vs. 2zz war here, lol...im just debating it, thats all. As it was put, i can lower the compression insted of the swap...i'll look around for parts

[Stang2Vibe]

Thanks guys for the updated info on the kit development. I thought that I read once before about the catch to them breaking that piston. I guess that was it, then. Lower octane fuel could have caused a knock or misfire condition that, in that high of a compression engine could snap the connecting rod. That's understandable.I think that the way to go would be to lower the compression with some heavier duty aftermarket components and then turbo it, especially if you already have the GT and this kit is already available. It's gonna be some bucks, but that should beat maybe 90% of the tricked out 1zz's out there. There's always gonna be someone out there with a tricked out freak engine that can do things that it shouldn't be able to do.A while back, I remember discussing on here a twin-turbo setup for the Vibe. One turbo would be set to operate at the lower end and the other one would kick in when the first one let off. Is this just a pipe dream or something that would be totally unnecessary? Also, there was talk about a Toyota dealer in CA that developed aftermarket performance stuff. It was West Corvine or West Covina or something like that. They were working on their own turbo kits for the Vibe/Matrix. Anyone have any updates on this?

[DopeVibeGT]

No, I'm going by professional specs. A supercharged 1zz only goes 0-60 in 8.3 sec. With the few mods I have, I'm putting down close to 200 if not 200 without turbo or supercharger. If I'm going to blow $3000+ on a turbo/SC setup, it better make it hella fast. I'd put money on the outcome of any turbo/SC base against what mods I have on my GT. Now, if the guy went nuts and did all kinds of engine work, IE Bore, port, etc, or NOS, no. I'm not crazy. But otherwise, I'll race them for $$. I'm not waring over the 1zz or 2zz, as I said, just trying to figure out why you would put a 1zz in a GT. I think it's crazy, but thats my opinion. 'nough said, I'm done.

[AKLGT]

West Covina in Irvine CA? I think they are close to the TRD plant the guy told me, but i don't think they develop anything themselves. i used to buy almost all my Tundra parts from them. gave me hella good deals! plus they are very knowledgable. i'm waiting on the unichip thing to pan out and also for a turbo/sc kit for the 2zz, decent ram air hood, converting my full cai to a short ram, dual exhaust w/ custom rear bumper, etc. i've got a long list of wishful items...

[Project Shadow]

0-60 in 8.3 with the automatic which has a non turbo time of 11.5!The base 5 speed is under 9.0 without the turbo...You guys are all hung up on horsepower, keep in mine RPM is directly related to Horsepower numbers but doesn't mean higher torque. Torque equals acceleration, not horsepower.If your car redlined at 12000 RPM your horsepower would be through the roof but you may have even less torque and an even slower car!
