Worth getting a gt15 turbo?

[Jimbo]

I currently have a t2, someone I know is selling a gt15
I know there both standard fitment turbos, but is the gt 15 better than a t2 in any way. Only ask as I'm gonna have the turbo off in next few days for the hg change

[Ricky]

Unless your T2 is dead, then not really.

[Mattcheese31]

not really mate . . . .T2 spools later but carries on giving much higher up . .

GT15 has some nice low down, pulling power, as far as BHP goes, it's outta puff top end.

A nice little turbo, and for the fun factor id swap it for the T2.

[Jimbo]

As far as I know it's fine boosts well just a bit laggy with the fmic

---

Is there any way of making the t2 spool a bit quicker

[Mattcheese31]

Ginge bums the GT15 fyi though, apparently where he lives you can't get over speeds of 50mph . . . .

[Mitch]

I have a t2 on mine and a friend has a gt15 on his, gt15 spools up really good but as said above it runs out of puff top end, i wouldnt bother really if your t2 is in working order!

seeing as i run a T2 now and have ran a K14 and a K03 in the past, i can't say i bum the gt15, but i know i loove the epic low spoolers.

ahhh was it a K03 on the Sigma then? . . . .i knew it was something GAF . . x

[Jimbo]

Gt15 good for 130bhp?
That's sort of what im aiming for. Nothing to drastic just a reliable torquey DT

[Tom]

T2 is laggy? Really? :/

I'd say so - would be "pushing" the limit, but achieveable. Keep sensible EGT's and pressures, you should be ok.

If you want that power bracket comfortably, keep the T2

You don't have a front mount do you?it was ok before but takes it time now fmic is on

sure you don't have a boost leak mate? . . . . most people report no noticeable difference after fitting fmic . . .

Sounds like you have a boost leak tbh. Unless your fmic is MASSIVE. Shouldnt take much longer to fill the system atall.

[Anton]

If your really going through all the effort of changing the turbo, get a newer more modern turbo?

Look at GT17/GT20, best of both worlds

[Tom]

Haha what he said ^^^ Ok not him the one above!

[Ricky]

Gt15's do not like high boost though, I think they overspeed very easily and self destruct. I think a K03 would be a better standard choice if you want something smaller as they are a little tougher, but they have all done 100k+ miles so most are getting a little too tired to be pushed.

[Jimbo]

No boost leaks still around 18 psi as before the intercooler was fitted. Maybe a bit more fuel low down will get it going better

get boost upped and more fuel, 18psi is Gay As Fcuk . . .

[Jimbo]

Yeah I plan on 22 24 ish once hg is done

put it out of it's misery . . .

A GT15 spools fast and runs out quick whereas a T2 come in later but punches harder. You'd have to find a way to fit it to an XUD exhaust manifold anyway as the GT15's came on HDi's... Unless you can swap the exhaust housings on the turbo's

[Tom]

Gt15s came on xuds aswell.

[declantg]

I had a gt15 on my xud

[ADV_93]

My bad! GT15's were on XUD!

[darrenjlobb]

Id run a GT15 over a T2.

Airflow isnt much odds up high acually, and you get a much cleaner / crisp drive.

But if your gunna change it, then put something better on
