Does anyone know of a Fmic that keeps everything in stock position for twins ?

 

Stock position as in regards to?

 

Battery ,air box and radiator, if possible

 

I think regardless of whatever fmic you get, the stock airbox may be too big. Your best bet would be the Blitz fmic, it allows you to keep the battery, radiator stays pretty much in the stock position although I believe the brackets do move it a hair and provides excellent cooling capabilities. Just my .02.

 

Alright cool thank you for the advise, I was only hoping to keep the air box because I just got a arc box

 

You still need to modify everything with the Blitz, stock parts won't fit either. The radiator mounts at relatively the same angle, but it's much higher and further into the engine bay. You would need to get a smaller battery regardless. The biggest battery you can use is something like the optima red top, and it would need to be mounted at an angle. I personally got a 51r miata battery so it could be mounted straight.

The stock airbox is definitely not going to fit, so if you want to use something like the ARC box you're going to have to stick with a SMIC

 

I have an OOOOOLD SMIC here at the shop that was more or less a copy of someone elses setup a shop tried to duplicate (rip off) around 98 or so, and it does in fact allow the OEM airbox, battery, etc. to remain, although a miata battery fits better. I Pulled a mold off of the ducting and have the dimensions of the core so a duplicate could be made. I will see about posting some pics tomorrow.

 

How much for cooler will the car run with a fmic over the smic?
