im a newbie when it comes to preludes... so im doin research for a friend of mine who wants to turbo his prelude. so far hes heard that FMAX is the best kit to go with. i really dont like the MF2 fuel mgmt. that comes with the kit. since you guys would know more... give me some feedback on why this and why that kit is better. i heard the prelude engine bay is pretty cramp and some kits are not as good as others for fitment. any feedback would be great. best parts... best bang for buck... blah blah blah.

 

advantages = faster car
disadvantages = tuning & keeping an eye under the hood.
Drag 3 if he doesnt plan on installing the kit himself.
Both should yeild similar results.
he really needs to learn as much as possible before getting the boost.
more air needs more fuel, too much boost and anything can go.

 

actually... i already know that. im talkin about the disadvantages and advantages of certain kits... not of havin one. DRAG3 isnt available for the preludes. highest it went up to was DRAG2. thats one reason why im doin research for him, too. i have LS turbo and i pretty much know whut im talkin about.

 

I myself haven't researched much on turboed Preludes, but a buddy of mine has a full FMAX turbo kit---from what I can tell, he is running a standalone management system--that helps a lot. He's stilling getting things tweaked out and such, however he says it's running a lot better than it was since he's started tuning issues. His only downside comment was that he believes his baby is begging for a bigger turbo. He thinks the FMAX charger just isn't big enough---being that he has a fully built motor on 9:1 compression. He knows that putting a T66 will improve things a lot more, with the numbers he's putting down at the dyno. He currently has a T03/T04b, and I would imagine that is plenty on a stock motor....Hope that helps any on your research.

 

I have the Gen 3. Its the most recent for the 4gen Si.
I asked Drag and they said the IC piping and BOV is upgraded.

 

putting a turbo on any b series motor is like eating. it's that natural. and tuning with the stock ecu/fmu or even the vafc hack is a no-brainer.

boosting an h series motor especially the h22a is far different.

the biggest problem you will have is consistency from the system and tuning. the only real solution for the h22a in my eyes is a complete stand alone. hondata, dfi, speed-pro, etc.

i used to run a custom kit on my 96 accord hybrid h22a. used all the good stuff, right trimmed turbo and the tuning was a bitch. my motor only had 9,000 miles on it when the turbo went on. compression/leak down was awesome across the board.

 

ok, i've done research on each of those kits, and they are all great. the F-Max is by far the best between the F-Max and DRAG kits. i didn't like the idea of the MF2 myself either. I priced customizing an F-Max kit, (different BOV, no MF2, no additional injectors, but with 4 450cc injectors etc.) I have decided though that i am going to go w/ a GReddy kit b/c i can spend almost the same amount of money on a GReddy setup w/ intercooler. But i am also going to be running high boost on a built engine. If you are looking for just a good bolt on kit, i would recommend the F-Max kit w/ the r-ideal headgasket that lowers the compression ratio. if you don't like the idea of the MF2, then i suggest 4 larger injectors and a V-AFC or a Hondata stage 4 + boost

Intercooler and piping:
fmax=very good fitament
drag=tight squeeze, fitament sucks

I have the fmax kit and the IC piping is straight forward with good fitament and placement. The intercooler is straight through design and has mounting brackets. I have installed a drag 2nd gen kit on a 5th gen and the piping is f#@ked up and is really long. From the turbo, it wraps around the battery and then goes to the intercooler. The drag intercooler is L-shaped and didn't have any mounting brackets. I had to zip-tie the intercooler to the bumper for a temp. solution.

I installed a bigger turbo (T3/T4E-60 trim) onto the fmax manifold by modifying it and i made a dumptube for open loop WG. You can read it here: http://www.preludeonline.com/showthr...threadid=68255

If I was to do it again, I would get the fmax kit excluding the turbo (t3/t4b) and fuel management (mf2). I would get the open loop downpipe from them also (you can choose between the open and closed). Then I would get a new turbo from Slow_ass_4dr and hondata 2b + 550cc.

 

hmmm interesting. so basically.. the best thing about the FMAX kit is the piping. thats pretty much it.

so in place of the mf2... what fuel mgmt would work? in this case... no mf2 and no hondata. will an inline fuel pump, vortech fmu 12:1 and stock injectors be good enough? this is what i run in my LS.... i figure it shouldnt be any different from the ludes.

 

whoa whoa whoa.... who said NOT to go with a Hondata... Quaalude and I each said you shoudl get a Hondata... the only differnce is that he suggested a stage 2b and i suggested stage 4b. the reason i said to go wiht a stage 4b is b/c you can adjust it yourself. you would have full tunability at anytime with a stage 4, but with a stage 2, you would have to take it to a dealer, or have someone with a stage tune it for you.

 

haha nah, i meant that "for now".. HONDATA is out of the question. he wont be able to afford it rite now. so of course, the next best thing is the standard fmu and inline pump setup with the stock injectors. none of that afc hack bullshiet. 12:1 fmu and inline fuel pump should do the trick for now rite? by the way...
i am very familiar with Hondata so dont worry about explainin it. at one point i was goin to get it for my teg, but i didnt have the funds for tuning. even modifying the eprom that came burned wouldnt be good enough to race with... so i opted to wait til i had money to get it and then tune it right with a lambda meter.

 

yea, fmu and inline pump would be fine....i would get a fuel controller to fine tune the fuel though....with 12:1 disc, u will be running rich in boost

 

i just got word that the DRAG4 kit for preludes are out. $3300.
