Ok i was thinking of selling my Evo and getting an MK4 Supra but dont wanna pay 30-40k for a used Supra TT with 30k,40K+ mileage on it. So now, im getting rid of 03 which i have experienced lots of "bugs" on and moving onto a 2005 GSR no sunroof this time either for lighter weight. So few quick questions before i get to my point..

-do the 05s tend to have syncronizer issues and TC issues especially like the 03s?
-how much more hp/tq do they put down to the wheels over hte 03/04s stock to stock

and my mod route i have in mind now is:

Buschur Stg. 4
Vishnu/Works p2 flash
Turbo XS UTEC
TME 6.5 Ti turbo
Buschur alky kit

I know the Buschur Stg 4 alone on stock turbo on race fuel pushes out about 380whp.

My goal is to daily drive my car in stop n go traffic, hwy, etc...daily driver for work basically and race pretty often. My main concern of sticking to a 16G(TME) is that by running the alky kit, im gonna be boosting higher maybe about 23-24psi daily. Would this hurt my turbo in the long run or will the titanium fins of the turbo hold up compared to a stock 16G running 22psi daily. I want low to mid 400WHP with the alky kit. How's it sound?

 

1) Don't have enough miles to know yet, but it hasn't been a problem yet among 05 owners. I only have 8k miles, but I've had 0 transmission issues yet after 35 drag passes (25 12.99 or better and 15 12.34 or better) and 3 autocrosses.

2) About 20 more whp on average in stock form.

I highly doubt you'll end up with low to mid 400s with that stuff on a daily basis, since you have 91oct, despite the alky. If you accomplish it, though, let us know...

 

hmm ok, so what do u think i will put down with a Exedy single/Fidanza aluminum flywheel added to that list along with the mods i stated above. The TurboXS will be professionally tuned, not sure who yet though.

 

What do you mean? The clutch/flywheel won't change the power output. On 91oct with full-time alky, I will guess around 380whp. I don't actually know all the parts involved in the BS4 or exactly how the P2 flash with UTEC on top is going to work, but expecting over 400whp without a built engine or head seems like a lot, especially on the pissgas.

 

05s have the same problems. mitsu tranny sux.
Synchro problems on all the gears. I know MR tranny is little better though. It felt alot smoother than my 5 speed tranny.

 

funny..i heard the MR's tranny is more notchy ???

 

you heard wrong. Shifts very well, even on the stock lube.

 

Not that I know of. I mean, it's possible that it just comes down to personal point of view, but I don't consider mine notchy, nor the other one I've driven. I ragged out both mine and my friend's on the drag strip, and both were easy to shift. I've only missed one shift in about 20-30 straight drag passes, and that was 4th gear on an attempted powershift where the shifter slipped out of my hand, but had nothing to do with the shiftbox. In daily driving, I feel it enter each gate, but I don't consider that notchy. Someone else may consider it notchy if they are used to some other car while I consider it smooth as butter, but we could be experiencing the same thing just from different perspectives.

Whichever the case, if the MR tranny is considered notchy, then there's nothing wrong with notchy...

 

Mitsu tranny is the worst tranny I have ever used. try reving up to +6000 rpm with 3rd gear and switch to 5th gear quick and see what happens. you will have 5th gear grind. No car I have driven ever did that. At least, it is happening on my car. It is has only 1200 miles. almost brand new.

 

Why exactly would anyone in their right mind go from 3rd to 5th?

 

Well, if you are pulling hard in 3rd, then get to your desired mph and want to just put in 5th to cruise, you might do it, but I don't see how it is a good measure for evaluating a tranny.

If I do this from 3rd to 5th or 6th, it doesn't grind. Nothing grinds in any gear at any time, but maybe the 6spd is better.

 

sorry to hear,
but sounds good that you are still staying with an evo

 

That is bad on your syncros. Never skip gears, its just adding stress to an already mediocre part.

 

So going to 5000 rpm in 1st then shifting to 3rd is bad news? Normally I don't skip gears but after seeing my friend with his Vette skip gears to save gas I figured I would try it and see how it goes. Amazingly the car seems to pull just fine using part throttle even though it drops in the 2500-3000 RPM range. Of course I'm not speed shifting but I'm not sure what the dangers would be.

 

Why does everyone think 03 have a lot of bugs. Its the same car (99%).

my 03 with 22k has been perfect! (clutch too)
