R34 Gtt Triptronic Gear Box

[mxtcy]

Hey guys n gals

Just wondering how much power a stock gtt triptronic gear box can hold without going bang. I've done a few mods and am about to up the boost and am just wondering how much power:

A: I will have with these mods aprox

B: How much power the stock triptronic can hold

C: how much more boost should i wind in.

Mods so far are pretty basic

FMIC

turbo back 3 1/2 inch zorst

pod

Curently running stock boost, but looking to run around the 12psi mark (stock turbo)

Sorry if these questions sound a bit newbie, but i'm still a bit new sto skylines, i'd always been a 180/ SR20 person lol

talk to Stan - satanic.. he had around 200kw going through his I believe..

I think past 200s you need to look into transmission coolers and valve body mods to reduce heat, not quite sure though.

Been told by shuan duns from boostworks that the stock 34 tiptronic box can hold 240rwkw.

im running 227kw with standard tip box..standard cooler too...seems fine to me

Can I ask what you're running in terms of managment/turbo etc E-Lu?

I killed mine at 228rwkw. I went to the track a lot. Heat kills them so do a couple of things. Be very careful when it's cold - no boosting or highish revs. It takes longer than your engine to warm up too.

Put a transmission fluid temp guage in your car. Cheapest safety device ever. I just used an oil temp guage and plumbed it into the send line to the transmission cooler. Keep an eye on the temps and don't let it go over 100 degrees.

Another thing you can do is a valve body upgrade from MV automatics in Adelaide. About $350 plus fitting. You take yours out and send it away then get it back 2 weeks later and refit. I did it myself in my garage without much knowledge and it was a c**t of a job but it was possible.

The valve body increases the speed of the shifts which decreases the heat created.

You could try putting Redline Racing ATF in. I put the High temp ATF in but a, it was too late for mine at that stage although I didn't know it at the time, and b, I should have put the racing one in. The racing one has no friction modifiers and every other fluid out there does. The friction modifiers create slip to make the shifts comfortable. Slip = heat = death.

Also I don't believe you need to replace the standard R34 auto cooler. If any R33 owners are reading this - you do need to replace it.

Very informative post Abo Bob thanks for that.
