Can’t believe this doesn’t have more views, ever since the sti was canceled I’ve been waiting for someone to swap it

Love watching guys like you build these VB WRX. I enjoy my VB WRX , but think I will be doing a Cobb stage 2 and calling it a day. It’s my fun car and don’t want to have to do trans and brakes and so on and so on.

@JoeyMontalto 10 ай бұрын

Yes I agree Cobb stage 2 protuned is probably the max the trans can safely take. The tuner will limit torque to save the trans. As far as the brakes. You can always swap out the pads and fluid for a better bite. I’ll be doing some brake upgrades soon!

Now that the 2024 WRX has eyesite, do you see anyone manual swapping the new gen outback and legacy's? The thought has popped in my mind for when my 22 legacy tr580 blows.

@matt-5599 8 ай бұрын

Not to nit-pick, but can we dig in a little on the dimensions where it the STi clutch is larger? I am doing an STi transmission swap on my '22, and the STi clutch I have seems to measure exactly to the O.D. of the clutch on the factory service manual for the 22, which is 240mm/9.45mm. Just want to help clarify on that spec

@DarkWolfWRX 10 ай бұрын

Ive not had any issues on my 1st gear. Though my 3rd gear seems a little goofy(not grindy but hitting third itself) which I THINK is due to the kartboy shifter, I am not a fan of that one. I do have the clutch line from Jeff as well, just havnt gotten it installed yet.

@JoeyMontalto 10 ай бұрын

Install the clutch line and try it out. I have ran a kartboy shifter on all my STIs and never had an issue.

@DarkWolfWRX 10 ай бұрын

@@JoeyMontalto I think its just the feel of the shifter at this point. I am running another secret Perrin part thats involved but I dont this its due to that. The Kartboy shifter just feels very, clunky to me? Or it may be the STI trans itself as I have never driven one before. Though today I do notice a squeak from the clutch pedal. So thats fun haha.

I’m looking for a new platform to tune moving on from my 9th gen civic si. I can’t decide if I should get Vb wrx and do Sti trans swap or buy used Sti. I have a lift and garage full of tools. It’s just the new fa24 motor looks very appealing. Please leave your opinion

@JoeyMontalto 9 ай бұрын

The new fa24 motor is great. Only needs the sti trans paired with it. If you have a lift and the tools I'd recommend the VB and doing the trans swap

@aptkeyboard3173 10 ай бұрын

I wonder if it’s possible to put a limited slip differential in the VB without swapping the transmission? I think the open differentials are a big drawback even having AWD

@JoeyMontalto 10 ай бұрын

Yes it is possible but then you will still break your gear set because the design of the transmission being a split case. It will cost more money to build a wrx trans and even when fully built it will still be weaker than a stock STi trans. Complete waste of money to build the wrx 6speed

I might have missed it, but regarding the SI drive controller, does yours remap the throttle and adjust boost targets as it does in the STI? Or is it just to get the DCCD control?

The si drive controller is only to adjust the dccd. The knob to change from I-s-s# does not work

This video is very informative. Do I understand correctly that after transmission and diff swap speedometer and current gear indicator won't work correctly? Is it a problem and if so is there any remedy for that?

@JoeyMontalto 10 ай бұрын

I did talk about that in the video I believe. With the iwire harness everything works correctly except for 5th gear indicator. The gear indicator says 4 when youre in 5th. All other gears show correct. The remedy was my retune from my tuner. When I knew it was ready for the tune he sent me a file and it now shows 5 when in 5th

When you did this swap, the gearing ratios changed correct? Is it possible to get the gearing ratios to be the same as the VB after the STI swap?

@JoeyMontalto 6 ай бұрын

Gear ratios are very similar compared to the stock trans. They make different gear sets for the STi trans if you wanted to change something up but that would be more money to swap out the gear set

@bobbyjames8323 10 ай бұрын

How much did your fuel economy change? Also how did this change your shift points?

@JoeyMontalto 10 ай бұрын

I have not noticed any fuel economy changes and the shift points are basically the same. The ratios are close enough that even without a tune the gear shift indicator was still accurate. We confirmed this when we retuned for the trans.
