exhaust 4 a TT 2+2

i plan on doin the TT swap in my N/A 2+2 auto. anyways...i know i will need a custom drive shaft and still use my N/A differiential. but i was wandering how the 2+2 exhaust works. is it just the 3rd section of the exhaust that is longer to make up for the longer wheel base of the 2+2 or will i need to get a custom cat pipe section to make up for the length. i was wanderin cause i already got a stillen aftermarket exhaust that is just the third section and i would really like to keep it because i am really happy with it.

while im doin the swap what should i upgrade besides turbos, clutch, flywheel, and i plan on doin the 60,000 mile service while the engine is out. (timing belt particularly). is there anything else besides these items and internals that u have to pull the engine and trans to get too? i dont want to get it in there and then a month later decide that i need to pull the engine to upgrade somethin.

what company makes the cheapest turbo upgrade that would be worht the money?

Well thats the wrong mindset to begin with.

Its nice to save money but don't ever skimp on performance parts that are actually going to be doing something important (like turbos).

I'm partial to 530BBs


A better question is how much money you have and how far you plan to take that car. That will guide your purchases.

i have heard that the n/a differential is different from the tt diff. i have a friend who wants to take a z diff and put it in his 240 and we were talking about it with a guy that has a tt (he knows his z's) and he said that he would have to get an n/a one because the tt one wouldn't work.

I've heard ball bearing turbos aren't worth the extra money.

ok. i might have expressed myself not like i wanted to. i plan on upgrading the turbos but not as soon as i get the swap because i wont have the money. i will wait. its not that im skimping its just that im not gonna save $15,000 for 2 years and then do the swap. id rather do some basic things then save up more money then upgrade turbos. i never said that i was gonna be done upgrading things. i just wanted to know what r soem things to think about upgrading while the engine is still out of the car.

does anyone have the answer to my exhaust question?

I've heard ball bearing turbos aren't worth the extra money.

from what i've heard and read, the only benifiets of em are a *slightly* quicker spool up time, not worth the extra money in my opinion.. altho, it is cool to say you have twin ball bearing spooley things.. lol

i work on car alittle , exhaust is not the main prolbem , custom is not that difficult .
custom drive shaft hmmm i don't know about that
i read so many infor.. about TT swap but this is first time i heard this .

Dude you've gotta work on how you compose yourself in your writtings... I cant understand what your saying. Not to be an ass... Just letting you know.

About the swap:

Custom driveshaft will be needed... $450 i've been quoted at.
Custom Mandrel bent exhaust pipping will run quite a bit. But is NECCESARY.

Twin Turbo Differential is a must.

Think: Your stock Non-Turbo Rear End is expecting about 175-180hp by the time the power gets back there (222hp at the crank. About 175-180bhp by the time it gets to the wheels. So that is a rough estimate.)

So when you increase that power to 300hp at the crank, and about 265-270bhp (Brake Horse Power... Or at the wheels) your not going to be holding much traction.

You will have to have a LOT of components custom made. And im not talking custom like ricer mind-set. (i.e Altezza tails)

Im talking expensive, labor saturated custom.

Are you sure you can afford this project?

I will do something for you though... I will call my suppliers in Japan. And see if they have any 2+2 Twin Turbo clips, with driveshaft, and exhaust laying around. And get a price on this.

I will only do this if you are SERIOUS. (it is a LOT of time for me to do this... So by serious, I mean "I have money now, let me spend it" Serious.)

Hit me up man.

Wes, Brake HP is flywheel horsepower. It's not wheel hp.

and dont forget that the TT and NA gearing is different. NAs have a 4.08 final

Precisely RX.

I could have made my point in fewer words I suppose. Gearing is different, you must change the Rear-End.

i am really interested in the swap but i do not have the money right now so do not worry about it. i will be probably serious when winter rolls around. thanks for your help though.
ok. i know about the drive shaft. thats a given. but i was reading somwhere else that u can keep the N/A differential.
and i was just askin about the exhaust because i always thought that from the cat back was made longer to make up for the longer wheel base. so i was goin to purchase TT down and test pipes and then i already have my stillen cat-back exhaust. then i thought i could piece it together. but really it is still not a porblem because my buddies dad can piece me one together if i give him beer money.
