I'm planning on doing the following upgrades within the next 6 months in addition to the Greddy Ti that I already have.

Option A

1. Downpipe
2. Cat Delete or Hi Flow?
3. UTEC (will be tuned on a dyno)
4. Cams (264/272)
5. Walbro Fuel pump (if needed)
6. Injectors (if needed)
5. Guages (not performace related)

OR

Option B

1. RRE tuned JICs.
2. Downpipe
3. Cat Delete or Hiflow

I should have approximatley $2500 to spend on these mods and I'm wondering if the performance mods above will affect the reliability of the clutch and TC. Actually the question is if the clutch will be able to handle that amount of power. I know more power will affect reliability to some extent but i'm not sure if the stock clutch can handle the extra power. Note that I DO NOT launch the car and don't go to the drag strip either. I do however intend on doing a few DE events (road course).

So with that back ground, I'm wondering if I should do option A or B. I do not want to go thru the hassle of fighting with mitsu on clutch warranty nor spend a few grand replacing the clutch or transfer case so I will appreciate if I can get your honest opinion on this.

Also approximately how much whp am I looking at with those mods.

Feel free to give your opinion on these mods too...

thanks in advance for the help.

 

that's not enough power to do anything to the clutch or transfer case.....granted you say you don't launch. What breaks the stuff inside the transfer case (most of the times, the front diff) is extreme shock from sudden torque. The stock clutch will hold that power on your option A for awhile but it'll wind down obviously quicker than just basic bolt on mods....Now the choice between option A and B depends entirely on you....do you want a car that handles extremely well or do u just want to have some fun and get some more power out of her.....it's a win win situation, just gotta know what you're gonna really use it for. John M. @ RRE is great with the JICs, I've heard nothing but good things. Have fun.

 

Thanks for the reply. So you're saying that a sudden downshift from 3rd to 2nd may take out the clutch or transfer case That's the only way i can think off when there may be excessive torque being placed on the TC....but if you match your revs properly it shouldn't happen...right? Or if you upshift from 1st to 2nd or 3rd and match and do smooth engagements then I think it should be fine too. Only dumping at 6Gs is where I see a lot of stress.

thanks!

 

Your stock clutch will be OK with the mods. It all depends on how you drive. Do you slip the clutch alot, are you a good downshifter, etc.. Eventually you will need a clutch, but its impossible for anyone to give you a lifespan based on your mods.

no, what he is saying is suddden heavy torque loads on said components will break them... this is why mitsu uses a factory "slipping" style draivetrain... now when i say slipping i'm referring to the gradual clutch engagement that almost all the AWD cars now use... it allows the clutch to engage alittle easier to help absorb shock and save the TC ... I tihnk the first introduction was with the 2g gsx eclipse's.

 

I have pretty much the mods you have listed in option A, except the UTEC. Almost 11k miles and my stock clutch is fine.

 

a suddeen 3rd to 2nd? -_- I can see some damage if you continuously do somethin like this @ high rpms and rev match really crappy...like if you were revving 4-5 k in 3rd and downshift to 2nd with no rev matchin whatsoever and dropping the clutch without slipping. That over time can cause problems obviously....in terms of real shock, I'm speakin of hardcore sidestepping the clutch @ 5-7k from a standstill.

 

How much power you making?
