GT3076R so laggy ??
Think of how often you drive part throttle or just ease into the gas in 5th and accelerate easily. It's not always about full throttle and racing someone and the great torque and throttle response of the stocker is one of the cars great attributes that is immediately missed when upgrading.
Bernardo, gave a great review of a 3065 and don't try to accelerate in 5th until 90mph.
I for one am all for big turbos and don't mind the lag most of the time, but good post to the OP and bigger isn't always better for everyone.
A lot of the tuners don't rate the GT3076r as a good turbo and I agree the spool feels almost identical to my GT35r but GT35r hits so much harder!! I recently upgraded from my RnR supplied PTE GT30r to a PTE GT35r.
From memory & my old dynograph my RnR Gt3076r kit hit full boost 24psi at 4800-4900rpm, in 3rd gear...never dynoed 4th before though.
Honestly, I would never use the GT3076r again from my experience and the reviews I've read...if I want a quick spooling turbo in that same power range it would be the PTE BB 50 trim for sure.

What the hell is RNR doing wrong? Or is it all just a co-winky-dink?
And when i was talking to jeff from full race he said the gt30 was a very good turbo for pump and low boost, says it spools qiuick. But im sure he was running his manifold.
i have the RNR GT3076R turbo with the surge cover. it's so laggy. my evo always run strong with the evo 9 turbo on my 04 evo. it made 365whp on 91 octane and 385whp on 100 with 26psi. i have every mods you can possibly do the the car.
the turbo start to spool at liek 4000rpm and full spool at 5500rpm.

i have more mods. but can't think of it right now.

I get 23psi by 36-3700 on the street easy in 4th. 3800 is in third. I would bet the fellow asking the question has a leaking wastegate. My guess is that the valve seat for the Tial gate wasn't installed which allows lots of exhaust to just flow around the valve and make it laggy. Have seen this before on a Honda.

I've had both the 3076 and 35 and found the 3076 only spooled slightly quicker than the 35, about 100- 200 rpm. Both turbos like to run high boost and spooled better the more boost I ran. I was happy with the 3076, but would not go back after trying the 35.
I would look at running a higher rate spring in your waste gate. Though I have not tested it myself, I've been told that running the highest rate spring you can get away with for the boost you want to run will greatly improve spool up.

Maybe somethings wrong 'internally' with your car...you should check it out. Do a leakdown & check compression...makesure cam timing is in sync with crank timing and all is Ok. Hopefully it's not a bad set of main &/or rod bearings as this would affect the crankshaft and spool up & general performance of the engine.

i can assure you nothing is wrong internally with the engine. but i will do a boost leak test.
oh hell no, lol. i'm swapping back to my evo 9 turbo befor i would even swap it back to stock intake manifold. lol
