Engine Non-VVTI Turbo??

Non-VVTI Turbo??

Alright I have a 1998 Corolla and its non-VVTI, I was just wondering if it would still be good to turbo it or would I be better off getting a VVTI and adding a turbo to it??

It should be fine to turbo. One of the early 8th gen turbo Corolla's was a non-VVTi, and it runs great.

just my opinion but i think non vvti turbos seem to work better than ones with vvti.

Curious; what makes you say that?

ive seen a few turbos on a vvti engine in the past and sometimes it works great, sometimes you get more of a turbo lag. My friends who rally with corollas and celicas, they all prefer a non vvti engine. I am not fully familiar with turbos since i prefer NA but i think it also has to do a little with the ecu as well. anyway, the newer turbos i think are better. i've been reading some good reviews on it that was used with the 2zz.

On the side note, i hear mechanics are having even more trouble turbo charging engines with CVT now more than VVT. hehe.

So running it turbo with VVT-i would make it lag more. What if i wanted to go NA and bring the compression up would i be better off with the VVT-i ? Because im interested in racing in autocross and stuff of that nature.

VVTI does not cause turbo lag

I have a T3/T4 turbo on my car with a .63A/r housing. It's got a little boost lag (which won't be a problem in a few months) but it's boost response is pretty nice when laying back down on the pedal and when shifting.

Well, my car's an auto so I have no issues losing boost or RPMs between shifts. Do you have a wide band on your setup? What's the AFRs doing when you shift? It sounds like maybe it gets a tad rich between shifts and bogs for a second.

thats called bogging, is that a tuned turbo or just slapped on. I have the same bogging problem and im not turbo'd. it's common with the 1zz and 2zz engines especially with Cold air intakes

the two cars i drove had 1nzfe engines. not 1zz. and they had semi tuned turbos. i've never had the bogging problem wihtout turbo. and a turboed 2zz that a guy that i knowhas said he gets it very rarely. but all my other friends with non vvti engines have absolutely no problem. anyway with my past experience, i learned to like super chargers a bit more with vvti engines. but this was again also 3 years back.

- Vamp how did you set up your car? what turbo did you use?

Ran 8psi on mine daily

vamp,... your car is amazing

that still has nothing to do with vvt i you how many cars have a form of vvti these days,..all that includes evo's sti's 350z etc. yeah i like superchargers better myself

wow, 8psi?? i musta done something wrong then because when i ran 8psi, i blew a piston. didnt sound too well.. hehe. oh well, technology evolves.

BTW, anyone in san fernando valley calif. with turboed 1zz? i'm quite interested now to see how it was accomplished.

Bad tuning I guess. I run 10psi. I could run a few more if I wanted to, but it's not worth the risk since I'm working on building up the block right now.
