you should consider getting a lighter flywheel and stronger clutch!

This is an excellent post which shows the real potential of I4 6. I know because I had one, with a buddy club kit, and i did most of the mods myself and the car performed awesome. One thing some of you I4 6 owners with body kits might try is to build a ram air intake (especially b/c kits). I had built my own cai, and using the right hole on the front b/c bumper, i was able to fix some light weight aluminum piping, connect it to the rest of the cai and BOOM!!! ram air intake. Let me tell ya guys it worked so well that at the begining it scared the $&!# outta me, the car was rockin, the faster I went the more power seemed to come outta the engine.
Sad to say my 6 was totalled in a accident.
But the good news is i just bought another I4 6 since i know alot about that engine, and im gonna go back to where i was with my last 6.
Well hope thats some inspiration for all you guys
Peace

I don't know if anyone said this already but if you go to Racingmazda.com they have an entire kit with intercooler for only $2900. And a 10psi it puts out about 250 to the wheels. If you want you can also check out the dyno chart by Clicking Here

That seems to be the same kit that someone on this board has for their I4. He actually has his turbo installed in his probe!

I was wondering how the gas mileage compared if you swap the INTAKE CAM from the a-spec to ze?

SO WHAT IS THE BEST THING TO DO. SHOULD I STAY WITH MY STOCK I4 ENGINE OR SHOULD I PUT THE FSZE ENGINE, OR SHOULD I GET A LS AND PPUT A TURBO KIT IN IT. ALSO WOULD THE TWIN TURBO WORK ON THE LS ENGINE. WHAT OPTION WILL GIVE ME THE MOST HP AND FASTEST 1/4 MILE.

Okay, first off chill on the caps...now that me eyes are back in focus lets talk.

SO WHAT IS THE BEST THING TO DO.

How deeps your pocket book$$$, how much do you know about your car and how much time are you willing to spend on it?

SHOULD I STAY WITH MY STOCK I4 ENGINE OR SHOULD I PUT THE FSZE ENGINE

Well considering all of the above it depends on if you want to make a N/A (naturally asspirated) motor or F/I (Forced Induction) motor, in case you don't know FI systems are turbo's and super's. Now, if you want to go N/A I say go with FS-ZE directly or rebuild the FS-03 with JDM parts(basically converting it to a ZE). The ZE is a good high compression N/A platform, thats what it was made for. You "can" buy the ZE and turbo it, it's possible but it involves way more time and tuning that anyone wants to do, and if it's not done right you'll blow it up or it just won't run right, period. Only like 3 people in the US have actually had a FS-ZE in their car running properly in history...something to think about, also thats not to mention a turbo'd FS-ZE. If you're going to turbo your motor stick with the 03. It has a lower compression than the ZE which is MUCH more tolerant to inproper timing and tuning that the ZE is. Just requires a little less and still gets huge gains.

SHOULD I GET A LS AND PPUT A TURBO KIT IN IT

Same as the above paragraph, just add a few horses for either setup (N/A or F/I) just because you're starting out with a little higher performance platform in going with the V6. The V6 also has a JDM ZE engine, it's the KL-ZE and basically is the V6 version of the KL-03 in the LS. Only diffrence is in most cases you'll have to relocate your batery to fit the F/I system in the V6 engine bay because there's not enough room under the hood, unlike the I4 where there is more than enough room.

ALSO WOULD THE TWIN TURBO WORK ON THE LS ENGINE.

Yes, there is a TT setup for the V6's, yet again only about 3 people have them in their cars running properly. They can net over 500hp but not only do you have to remove your batery but other things like air conditioning and maybe even power steering may have to be removed to make room for the second turbo. Along with huge gains in power come huge gains in down-time for install and tuning and in money you have to shell out for basically a complete over-hall of the engine because it's not strong enough to withstand that much power so just about everything will have to be forged and rebuilt, not to mention a new tranny too.

WHAT OPTION WILL GIVE ME THE MOST HP AND FASTEST 1/4 MILE?

The TT setup will for sure give you the most power and quickest 1/4 time but like I said, wiegh the facts. Something to think about... I have a friend that has a 95 Trans Am, this car has 285 hp and runs very high 13's and very low 14's 1/4 mile "stock". A properly tuned, turbo'd FS-03 rebuilt with forged pistons and rods, CAI, TP and Cat-Back exhaust running around 16 psi will run about a 14 flat...think about it. Now you've got a "stock" 285hp V8 Trans Am being matched by what once used to be 118hp 4-banger. Fun Stuff.

Cool story about a turbo'd FS-03

Great reply M.Hicks! As someone who has had the FS-ZE, I will tell you that you will have to either get the OEM OBD-I spec ECU from Japan, or get some type of standalone to tune even close to the 160+ HP it is supposed to have. After I blew my stock motor with a Zex Nitrous 50 shot (dry) I got the FS-ZE for my MP3, and only saw 120 HP and 121 TQ to the wheels. After that, the lemon engine I got from Japan ran low on oil one day, and I had to overhaul it. I ended up going back to the 9.1:1 compression with oversized pistons. I turboed it after that and at 6 PSI I was seeing somewhere around 180 HP to the wheels. And then last month, a rod broke on me after 5 months of boosting happily. I ordered and have Pauter Forged Rods and am waiting on my JE pistons to arrive. Meanwhile I am taking my engine out of my car in my garage. I hope my experiences listed above gives you some insight.

[budplaya_22]

Well those are two great post and they really help a lot. how much hp do you think a tt would be able to get and what kind of 1/4 miles times do you think it could get?

BTW, if you want the full story on what I have been through, here are a few links:

It's all about time and money my friend... time and money. There are no limits, no boundries, nothing. With that being said, a TT setup on a V6 you could be looking at anywhere from 200hp min up to 1000hp. :smile: I don't think anyone has broke the 500hp mark yet in a probe or a Mx6 but thats not to say it can't be done. Realisticaly, you're probably looking at 400hp with a good TT setup. Keep in mind a Corvette Z06 (top of the line production corvett with 405hp) runs a 12 anda half 1/4 mile. I can't tell you what kind of time slip you'll be looking at but probably somewhere in the 12's, with some experience.

This is a toyota supra performance link but...well, you'll get the idea.

would putting the head and the intake manifold (including J-spec cams)of a FS-ZE onto my I4 help my performance. And if not what JDM parts can I use to help me with FI.

[M.Hicks]

Putting the FS-ZE head, intake mani and exhaust cams will indeed help with performance. All those parts are better flowing and from the info I've gathered, the higher compression and better flowing everything is what give the FS-ZE the extra 50hp over the FS-03. Also, all these parts will help with FI, but if you're going FI I would say have a costom intake mani made. The FS-ZE intake mani was intended for an N/A platform.

I have been on since 12am finding out as much info as I can on turbo, supercharged, and a nos setup this helps out a lot I think now my head feels like a overstuffed clown car and I can't see staight, out of the three cars I have two were not built by me.

my question is simple I have a stock l4 2.0 with atx now what is the best way to go
