5SFTE Injector Question, Calling all 5SFTE's! Options

[WALKER]

I have a question regarding injector sizing with the 5SFTE setup. I am looking for answers from people that have a 5SFTE...especially you Manny!

I know when it was originally proposed to go with the 5SFTE design, the green top supra NA injectors were proposed because they were originally thought to be 360cc, however they turned out to be around 315cc. It seems then that people went to the 440-460cc injector. This seems to be quite a significant jump and I have heard many people say they are really rich in the low rpm's. How do you find at the top end under full boost (are you still rich?).

The reason I ask all these questions is because I found out that the MR2's did come with a 372cc injector and am wondering if that would be a good fit or would it be undersized? The part number is 23209-74160 and it came on the 01.11.1993-01.12.1997 3SGE SW20 (MR2's, maybe also on the 3SGE Celica's, not sure). According to witchhunter the flow is 372cc and it is a high impedance injector (13.4 ohm).



So guys let me know what your thoughts are on these injectors for a 5SFTE application, just wondering if they would be worth trying or should I go right up to the mid 400's like the RX-7 Injectors Manny is running?

Thanks.

i would stick to the rx7s manny uses. being a little ritch at idle is a small price to pay for more safetly and longer engine life.
