Default Gt35R/GT30R who can help me?

sigh....

i placed an order for a GT30R kit from staticXmotorsports but i asked them for a refund because of delivery problems..

so i am back again shopping for a turbo kit with a budget of around $3.5k

a Gt35R might be too much for me so i wanna stick with the GT30R.. however seeing that there are so many vendors now with turbo kits available im hard pressed to find which vendor would be the best way to go. im sure kingpin/topspeed/godspeed/harmanmotive are all great... after reviewing all the posts.

i am acutally kinda lost.. what should i do? do you guys prefer one over another? any advice? should i go with the GT30r or just bump it up and get the GT35R?

i dont wanna upgrade my internals nor am i gonna be running on race gas... i just want a safe reliable tune with 91 octane gas pushing 19psi pulling about 370~400whp.

any comment will be much appreciated. thanks

I don't know what turbo they have that would be equivalent to a GT30r, but a lot Deadbolt's turbos come very 'well-equipped.' www.boostplanet.com

FWIW, I have a Ultimate Racing GT35R kit (they also have a GT30 kit). The craftsmanship is very, very nice.

Technically, deadbolt sells GT's, but anyone know which of their Kong or Zilla series would be, if at all (still learning about turbo internals), similar to a GT30r?

Based on what I have seen, I would say SZ49 <= GT30r < SZ55. Of course, so much depends on the tune and the supporting mods that it is impossible to say. That's just my .02.

Search for a Topspeed thread where they have a superzilla 65 lb wheel turbo- Should fit the bill.

I've owned both the kingpin and Ultimate Racing kit am familiar with the perrin.

Every kit has it's advantages and disadvantages, which I would love to share, but would prefer to do so, privately. PM' me and I'll provide some details.


BTW I also was going to purchase the APS dr65, but decided not to due to limited turbo options.

thanks.

as i have been reading doing the searchs i noticed alot are saying that the gt35r is better then the aps dr65. but they are mostly vendors and these vendors are selling the gt kits. so i feel that they are a bit biased on their products. does any regular consumer have a take on this themselves?

Learn how to read a compressor map and that will show you the real differance between Garrett and everybody else. Garrett does a lot of RnD on their products, the competition uses the Garrett dual ball bering center cartrige and puts their own compressors and turbines on them this makes them cheaper due to cheaper materials. Garrett uses ductile iron to cast the turbine and housing and they use a lot of nicke in the cast for the compressor. Other companies also downsize the turbos for size fittment and to cater to the horsepower zone the customer is looking for. Garrett does not use an internal wastegate so to meet that demand the other companies (slowboy APS ect) use an internal setup. hope this helps

It all depends on what each person wants. I personally like fast spool, and I am not as much into the drag racing as I am into the twisty roads and road courses. I would choose a GT30R over a GT35R any day. But that is just me. For an STI that sees more drag strip time, the GT35R would obviously be better.

from my understanding, the dr65 is a GT40R...monstrous. Personally, when I do get a turbo upgrade, it will be a single 30r, or, if I am feeling feisty...Twin 30rs. As much as I love a big turbo wallop, I prefer a long, increasing power curve opposed to a high peak.

There are things that some NASIOC individuals (Cronic) have enlightened me on though. Although I consider a 35r 'laggy,' it will still likely have more power at any given level above 3k rpms compared with stock because of how much power it does produce.

Also, if boost is needed...downshift! That is why we got the six-speed.

This is NOT true...i'd consider it a gt30 moreso than a gt35. But i understand where you got this information stating it was a gt40, that is unfortunetly not true though.
