So l have to say the turbo is not for me.
With the contact im looking at the SC set up using the Rotrex.
This is new for the MR2 with no installs done at all. But a dozen have been done on the Celica 2ZZ.
My questions are
Is the 2ZZ a stronger engine than ours ?
A few have been done with injector up size to 630cc but no upgrade of their stock fuel pump . Is our fuel pump stronger than the 2 ZZ ?
Mind you ill only be getting 440 cc. Are the RC injectors reputable ?
The SC pulley will limit my increase to about 8 psi maximum roughly 260 HP. What do you guys reckon , Can our engine handle it without comprimising the engine.
Man these guys are running stock internals with CR 11.5 : 1 AND ARE BOOSTING 13 psi with no problems. Getting 325 HP From an engine thats roughly 160 HP !
With a MoTec and the right tuner will it idle perfectly and do all what the factory ECU does perfectly.That is idle, start up , cold/hot and not loose the beautiful revving engine ste up l have now. In other words totally transparent ?
Lastely anyone else considering also SC set up as to set the machining in CAD will just be a bit extra BUT if no one is interested l can save a bit as it wont be necessary because it will be custom.
The way it will be set up is totally invisible even to a trained eye. And i will use the clip engine for all the necessary designing.

Cheers
whoa yeah I can imagine the boost-building will come as a surprise, whenever I drive a boosted I always make sure I am close to where the turbo is about to spool its boost up....yes it does require a different driving style, and does take a bit to figure out on a per car basis...

AFAIK the 2ZZ engines pop like teenage zits. Oil pumps break left and right...running boost on a high compression engine requires you to run it safely with VERY GOOD TUNING....from what my tuning buddies tell me its all about fueling & timing to get things right at higher compression levels, it does remain less forgiving though, hence they prefer dropping the compression a bit.

Last I checked RC Injectors are market leaders
I hear they are even used in aircraft industry...must be reliable enough if its good enough for those airplance guys!
