Found these on the website of cats cams, they're out of the uk.
I got some doubts and questions... If the mr2 and celica have the same engine (1zz) is it possible to swap internals into my 1zz corolla 02 to reach the hp that they both output??? Please someone have an answer.
The only difference in the blocks are the mr2/celica have lighter(weaker) cast rods to make it more rev happy.The real difference is in the heads which have bigger valves and slightly bigger cams (im not sure on the cams, i cannot confirm) and different programming in the ecu.Also the intake manifold was different and the throttle body a bit bigger.
You can only run the celica/mr2 ecu if you have a manual trans as the autos between corollas and celicas were different and the ecu cannot control the trans.
I have a 5 spd corolla 2002. So i have the math the year if i want to swap my ecu? And are speaking from experience ? Im looking into and im shopping around for an ecu. I have my headers that i need to install and get my pip done. Once thats in im getting air and fuel ratio tune
I'm speaking from what I've learned reading different sites but ask anyone on here whos done it and they will confirm what i've said.Theres no way to tune the stock toyota ecu, you have to get a standalone or a piggyback and theres no gain in putting a piggyback ecu on corolla ecu vs a celica ecu so save yourself some money.
I wish I had more money for internal stuff lol
You gotta be patient and keep and eye out for deals, hit up other forums besides corolla ones for universal stuff like turbos and piggyback ecu's.For example if you want to do the intake manifold upgrade hit up a 9th gen forum where its a stock part and will sell for less than someone knowing you want it as an upgrade for your 8th gen.
As far for the throttle body can i use the one on 9th gen corolla as well??
You need to swap the throttle body and manifold.The 9th gen throttle body uses 4 bolts and ours uses 3 and the flanges are different.
Does the manifold bolt to the head directly?
Yeah the manifold bolts to the head no problem.
