FI s2k= Transmission upgrade?

[chriis2k]

Hi all,

I'll try and keep this short and sweet. This is my first post (Question). I usually wouldn't post anything as everything i ever wanted to know is already answered here or over at s2ki. But anyways..

I will be supercharging my S2000 soon. My goal is 400rwhp. At first i thought I'de just have to upgrade/ rebuild my diff (considering i would like to launch the car from time to time) but after doing a fair bit of research, I've come to realize i may need a transmission upgrade.. Is this true or can the oem transmission handle the power? I've read that 2nd gear on S2000's are weak and usually break with that sort of power.

If this is the case, can you please recommend some good transmission upgrades?
i know of the PPG gearbox. But that's in excess of 5k. Is there anything else out there that is possibly cheaper?

Thanks for all your replies and help in advance!

Chris

Generally I'd say for 400hp the stock tranny is fine, but you mention you want to 'launch'. I could go through a list of options but they are all covered in the FI section on S2ki so I'd just be duplicating posts.

However, bring a very generous wallet with ya.

Oh damn I forgot about the sk2i FI section! Doesn't matter, repost here for all the ozhonda users. It's good to have on both forums.
And thanks alot for your replies Aus! I think my sychros need changing anyways, ever since I bought the car 2nd to 3rd feels like it's hitting on something mid way through the shift. But yes I wanna be able to launch it and be care free! I understand that it isn't gonna be cheap, Ide rather keep saving up if it means piece of mind and long term durability!

I have the same feel of like it's hitting something before it goes into gear. but with first second and third. my diff is on its way and im looking at getting a puddymod diff ordered. 730 for shipping is quite alot, but i'd like to know i've got a awsome diff from the good ol Ben! i do need to do something about my gearbox as well because it is very annoying.

chriis, ain't my job to make life easier for OzHonda'ers (although you could be forgiven for thinking it is). If you want to spoon feed them you are most welcome to trawl S2ki and provide a summary.

ALPS: I've been saving up for a stage 4 puddymod for ages, and just before i was about to purchase i changed my mind and now im pretty sure im going with the r200 conversion. I'm spending all this money, may as well do it right the first time and never have to worry about it again! yeh i was quoted $750 for shipping from ben. The thought of spending that much on virtually nothing annoys me lol

lol im the laziest person ever.. so don't think i'de be doing that lol butt anyways, do you think the ppg sychros are worth it? Some people say its a band-aid solution, some people say its leaps and bounds beyond the stock sychros. Know anyone that's dealt with them directly?

Thanks again

I really couldn't say. I think honda9krm and Elaug over in the Aus section of S2ki have some experience with them.

Why dont you go to a diff and gearbox specialist and see what they can do?

Hey veyzzii, I want something that's already been developed/ tested/ proven by a reputable/ well recognized brand/ company. I don't trust or rather wouldn't take the chance with a specialist, specially from Australia where hardly anyone works with s2000's. Thanks for the tip but. Worse comes to worse, I'll probs end up going that route anyways

Surprisingly Australia is one of the world leaders in this sort of performance modification. Sure Puddy does some great work beefing up a S2000 diff but the bullet proof solution is Diff Technics R200 upgrade. Diff Technics are Australian.

Likewise, one of the best transmission upgrades is by PPG. Guess what, PPG are Australian.

I love what Puddy is doing and if it wasn't for freight I would be all over it. Instead I found a highly regarded Aus diff (and gearbox BTW) specialist and worked with him to upgrade my diff. There is no OS Giken or Kaaz center. The Torsen unit is fine and not the part that fails. I supplied a new crown wheel and pinion and the specialist had new end caps machined and a steel collar turned. The result is a diff that nicely holds the power my car generates. Took 9 months but the results are impressive so far.
