What's up guys. I have a simple question for you turbo gods. How much psi can I run on a Greddy kit for a B18C1???? I know the Drag3 or Rev-Hard is better, But I can get the Greddy kit for a discounted price and I just wanted to know how much can I run.

Oh I'm putting Rods,Pistions, 550cc inj, FPR,Fuel Rail,255lph Fuel Pump, C.N clucth,Toda flywheel,Hondata s200w/boost,Full MSD ignition system on the engine.

So how much psi can I run with that setup guys?????

Thanks.

Remember this you get what you pay for. I would definitely go towards the Rev Hard kit. the highest i have ran them is about 12psi the turbo doesn't support boost levels higher then that it will boost higher but will be in efficient.

So you got the greedy kit to go toward 12psi or where you referring to the Rev hard kit???

TEAMGENDAI

the greddy kit maxed out at 12 psi rev hard stage 2 and 2c max out about 22 psi and the hypo is like 30+ i would just get the rev hard kit.

The Greddy kit does not max out at 12psi. It's good up to 20 psi which is up to 300whp. I don't think and street person needs more than 300whp in a small honda. Even a t25 0r a t3 is good to 1 bar then the top end dies off. I've never seen a turbo max out at 12 psi.

TEAMGENDAI

you might want to read a little higher before you speak. i said they were not efficient past that.

roydogg

Why wouldn't it be efficient past 12 psi? Cause it's a small turbo? It'll just spool up and hit full boost sooner than a t3t4 from the revhard kit. And you'll have to shave your block with the revhard kit too. not like the greddy or maxrev which is a bolt on kit. the new Evo 8 has a td05 15g turbo and is at 20 psi all day everyday and is pretty reliable from a mitsubishi dealer. You should learn a little more before you speak .

ive boosted a a greddy kit to 12 psi.. it wasnt fallling off even at that..im pretty sure it efficient a lil past 12 prolly dies off at 1 bar.. oh and thats the 04 that i had

Thank you . If the greddy gets upgraded to a 20g it'll be a killer. And by what rpm did you hit full boost? Probaly didn't even have any lag huh? The more whp you have the harder the traction is on a street car so just buy something that will suit your need. Cause I think 250-300 is enough for me.

b18cTurbo

the 18g turbo is good for 350whp max (18 psi) you will have to upgrade your downpipe ,exaust,wastegate ,fuel management etc... the exaust manifold suck but its ok

Forget fuel, forget tuning, forget effecieny.... getting the GReddy 18G to HOLD boost above 12-13psi is not going to happen.

Just ask b00st, he tried to run the GReddy hard, and he made good power (325whp +/-) @15psi, but shortly thereafter blew it when the wastegate spiking got out of control.

If I learned one thing from these GReddy's, internal wastegates SUCK!!!!

your 100% right .. Joe (falcon) did some porting to the internal WG and upgraded the size of the flapper, I dont know what came of it tho.

Ill give him a PM, but i thgink he ditched the greddy setup and went inline pro mani and SC48 turbo or something like that.

Ive got the Greddy 18G kit and i have no prob with it, i constantly run 10psi daily and have had it tuned to 14 psi, and never fluctuated. boost levels held steady the whole time on the dyno and on the track... upgraded dp to 2.5" and Apex'i N1 cat back with holley high flow cat, Apex'i AVC-R boost controller and hondata tuning with 550cc RC injectors. cant see why i couldnt hold more -- ive never heard of this problem before, on 9 psi i made 255whp and 206ftlb
on 10 which is daily tuned now i hit 269 whp, cant remember the other numbers exactly right now but ill get them soon gotta find my chart at home.

I do have forged internals but no sleeving so 14 psi was a one shot run andi dont want to chance it right now with cracking sleeves.

ATgrills.com

what? I ran the 15g kit on my B18b1 at 10 to 13PSI daily on a stock LS, not a single problem all summer.. and this is the 15g turbo not the 18g!!

OHH ****!!!!!!!!!!!!!!!!!! burnnnnnn.......... damn i feel the heat...

DeepSi

Alright, the TD05-18G loses efficency around 18psi.

As for not being able to go beyond 12psi. Yes some people have had problems going over, ALOT of others have been able to go beyond 12 psi to the 1bar and higher range.

Yes Internal Gates are not the best, and the desired setup would be an External Gate. However, you are buying a street legal kit which makes the car somewhat like a stock turbo car. This is important for the places that have emmissions. You can not have the best of both worlds.

So please stop your bitchin and putting down the greddy kit. You have to make sacrfices for somethings and people dont understand that.

greddyturboGSR

I agree with what DeepSi is saying. Most people going with the greddy kit are doing so for specific reasons. People who don't want to have to deal with emmissions or people new to FI that want the most complete bolt on kit to get started. I went with the geddy kit because I wanted something bolt-on to get me started and I have been boosting it for almost a year and haven't had to do anything other than switch to synthetic oil and change it every 3,000.

oh yea...........and get used to rotating and replacing tires often!

one of my friends has been boosting 13 psi on his greddy kit fo allmost 2 years

greddyturboGSR...What are your E.T. at the track looking like???? At what psi??
