Not bad. the power band look pretty solid.

This is really good info, what makes me wanna get this turbo the most is the warranty. I'm still not sure who to get it from. I've heard good things from ken but idk the other guy. Also I think I saw an external wastegate on that guys turbo? I thought it had an internal wesgate?????

[TheRealSy90]

Get it from Enjuku.

That was a bov you were looking at in the vid...

[c-los13]

you need some motormounts lol but yea the isis turbo does good. ive seen plenty of guys run it no problem.

i am running their ka turbo manifold and clutch line along with other miscellaneous parts from isis and everything looks legit.

If you needed to do a rebuild on this i wonder if a t2 rebuild kit would work?


also could you put a t3 housing on it?

[miamiman323]

Ive bee thinking of picking one up aswell. Did you use any of their other products for the install? Ive been thinking of buying there whole kit, figured it would save some time and i already have z32 maf and injectors.

Still running the RS3871? I'm debating the RS3871 kit for my ka-t, so any input is appreciated!

Not bad. the power band look pretty solid.

Not really if you look closely. First RPM column is 4000 rpm.
So basically barely hitting 200whp @ 5000 rpm...

when do you hit full boost?

[JJ Alfano]

As an update to this: This tune melted a piston, so its not reliable lol.


We rebuilt it with BC head parts and a cosworth headgasket, upped the boost and had a real tuner tune it.

It made 320whp/290tq at 18psi. We then tweaked a little more fuel on the top end of the powerband to make it safer for drifting, which brought the numbers down to 315whp/270tq.

I loved this turbo, and it was great for the price!

I also ran this turno on 18lbs right around 310 like post above said. Beat the sh|t out of my car with this setup and it handled all of it. Deffently would get again. Sorry if I brought this back from the dead I can't see the date clear on my phone
