    Goth.....360 headers...360 test pipes or hyperflows(both the test pipes and cat will have to be lengthened).....and a 360 Capristo or X-Ost w/outlet pipes modified to fit bumper exit points.
    I really like Group77s' exhaust design......you could fabricate that with bigger ID piping.
    I also believe Group77s' throttle bodies and MAFs' would work(maybe some slight mods) on the stock 360 plenum and intake....may go 360 all the way...if I'm not mistaken the 2.7 and Challenge had 2 MAFs'.
    As soon as someone can check out the difference of 355/360 intake then it will be just a matter of redesigning to fit(sounds easy..but stuff like this never is..lol).

    Don't think I'm going to make 2,000 posts by the weekend...oh well..there is always next week..lol

    That sounds good :D!! I am still researching the "dual" MAF retrofit to my single MAF ECU (anyone can help :) Please?!!!)
    Otherwise it would be a big process to make a 360 ECU setup work :(.

    Hell, if needed I will make my one MAF feed two throttle bodies :eek: !!!

    Hi Bruce, The 355 and 360s induction system are the same configuation and the power is not that much different (375 to 395) I think that gain came from better engine management and increased displacement vs the plenum change. So I'm not sure you would benefit much from the expense and time it would take to do the swap. Although the top end of the 360 is lot better in the mechanical looks department than the 355, it might be worth it just for that, hahaha. Regards, Vern

    Very true though I think the "individual" throttle boddies can vary air from cylinder to cylinder just look at the headers in the prior posts. So dual throttle bodies is the way to go IMO. So at least each bank of cylinders will get the "same" air. :)

    I'm not sure I understand your comments. The individual throttle bodies flow better/more air than the two would on the 348 thats why Ferrari changed to that on the 355 and probably one of the main reasons(that and maybe the 5 valve config.)for the increase in hp from 348 to the 355. You can actually adjust the flow more accurately with individual throttle bodies. By using a monometer you can set the airflow to be exact on each cylinder.

    P.S. After reading more throuthly past posts are you talking about throttle bodies or airflow meters?

    Now we are talking!!! I will get one ASAP :D

    BTW My original concern was that the individual throttle bodies air flow might "vary" from each other. :( solved with the "manometer" :) .

    Bruce,

    If you dump your 355 ITB's for the 360 units let me know. I'll help you finance the 360 parts by buy your 355 parts. I would like to do the 355 ITB's on my 348 like Plugzit's. I like the look and would like to cut the deck lid and run the ram air from the roof right into the to of the deck lid. I'm racing anyway. and Plugzit did all the parts develoment and I am lazy.

    Best way to tell...buy an intake gasket for a 328 or 348 and a gasket for a 360 to verify spacing of ports-hopefully the gasket on a 360 is one piece-328-348 spacing is the same as 355, but 355 has individual gaskets. cheap way to find out.

    I was thinking about this same thing last night....could also verify exhaust by overlayng 355 with 360 gasket......that is just the starting point though.....on intake it still leaves me guessing about the angle of the mounting flange(intake) matching angle of the heads....and distance between right and left cylinder banks(the 360 intake appears to have fixed lateral crossflow between down stacks and a one piece top cover????...if there is a difference in the distance between cylinder banks...all this will have to be cut and shortened or lengthened as required). Height is also a concern....cut the deck lid and put an F1 ram air cold intake???...lol(wow).

    Thanks for the help!!

    Not a problem......will begin work on this project hopefully in May.
    I think the ram air is an awesome idea and would love to see it done.....just think......nice cold air coming into the intake....getting rid of those big old nasty air hoses that get hot as h#ll along with the air it's conveying.....put in some short hoses in its place and let it cool the engine compartment.

    Hi Vern...I am not sure I understand your post......the 355 has individual throttles for each cylinder and no crossflow between right and left down stacks(throttle bodies)...on the 2.7 there were 2 air flow meters being fed by 2 separate air boxes......on 5.2 the 2 seperate air boxes were made common by using a Y connector which fed a single air flow meter.............the 360 is radically different. The 355 intake is a f#@king nightmare...the 360 is very simple. The 360 has only 2 inline TB(one per side) being fed by 2 air flow meters(also one per side)......the airbox/filter is a large common trough design(single inlet w/two outlets) feeding each AFM and TB......the intake down stacks are also common with a whopping 8 crossflow tubes(4 to the right and 4 to the left). The 360 appears to have a much greater air flow and pressure balance....and therfore the capacity to handle the demands of a higher hp motor.

    Goth.....I still like Mr Os'(GruppeM) street/race exhaust the best....IMO use the 360 stock header w/heat shield and fabricate everything else like Mr Os' setup...you could put some flanges in there so as to swap between cats and no cats for emissions testing.

    Sounds good to me. I would want to make it as stock "looking" as possible. The length mods are no problem. I do like Mr O's exhaust it is clean and simple.

    Any opinion on how I can convert to to dual MAF's from one?? :(

    Goth....2.7 355(95) have dual air flow meters......as far as I know all of the Challenge cars(95-99) used the dual set-up.........there was some guy on eBay that has them for sale....he has been trying forever to sell them....do not know his user name though.
    As for the ecu ask Group77 for some insight.

    My shadetree thought....maf on one bank only, alter the resistance output to compensate for 1/2 the air.

    I wanto know if I can go dual's short of selling my 1997 to buy an early car :(. Unless I can find a black on black spider :rolleyes:

    Hmmmmm, I think I may lose 50% resolution though :(. I guess using one to feed both is the only way for now. Thanks for the input Bruce :D ;)!!

    and I promised myself I wouldn't start modding the Ferrari, with the STi sitting in the garage with barely any OEM parts left on it. hmmmm, the wheels are turning...:) :) :)

    Why wouldn't you modify the Ferrari? It ain't like it's a one-of-a-kind perfect collector's item.

    true, I guess it's all relative. certainly more collectible than my Subaru :) And if I get too aggressive with timing or boost and blow the motor I can get a new one for less than the 3 yr maintenance on the 355!

    Ok, what is the story with this cross flowing, pulse benefitting intake of the 360???? Does it add any real power or is it just for bottom end "driveability" ????
