greddy turbo power - Honda Forum / Acura Forum

what is the most power you have seen a greddy 18g turbo on a gsr motor? i am trying to push 300whp on my integra with blox IM, ctr cams and the greddy kit. if i cant reach that goal then i am going to get a t3/t4 kit

Achievable between 8-12 psi. But you need a better fuel management like I said so many times on your posts. You do not need a T3T04 kit. If anything, just get a manifold and the turbo.........

yes i am getting a better mangament, i am purcashing a hondata s200b with p28 soon, so the greddy kit would be enough to push over 300whp? and yea if i was doing the trade, we are just trading the turbo and the manifold.

Really you think he can hit 300whp with that little boost on that turbo?
Maybe if he had a larger turbo I could see that, but i'm thinking it may take more then 12psi.....Maybe i'm wrong....

you can hit 300whp with the greddy kit. I've seen numberous dyno sheets proving that! You would probably do it a lot more efficiently with a SC61 though, but It can be done with the 18G. It will require a fully built motor of course!

i dont think you need a fully built motor to hit the 300whp range

Your right. I'm thinking that it's going to take a little more then 12psi to make that 300whp....I dont doubt it can be done because i've seen it before....

out of a full race or peak boost kit i have seen those kind of numbers stock block

Are we talking about a full-race Kit or a Peak boost kit?
Argggg, I've seen well over 300whp with less then 10psi of boost using MUCH larger turbo's then the greddy 18g. My whole statement was directed towards using the 18G turbo, not a t3t40E, sc61, or t3/60-1....etc...

Sorry dude, but i'm well aware of the power capabilities of other turbo's on B-series motors, I was just questioning the greddy kit on this motor because of all the kits out there greddy kits seem to make less peak power, more power down low and run out of steam faster then the other kits that use larger turbo's....It seems like the greddy kits make closer to the 250whp range with 10psi or so while the other kits (peak boost, full-race,etc) seem to make over 300whp with the same amount of boost...A lot could have to do with the tuning differences (greddy e-manage vs hondata or aem ems).....
That was my whole question....Thanks

thermalfi'd16 · 11-21-2005, 05:58 PM

You know what.......... that is true. Now that B16ahybrid pointed it out, it may take more than 12 psi to it the 300 whp goal from an 18G. 12 psi on that turbo will be about 75% efficiency therefore adiabatic stage is soon to reach.

It can still be done, but will mostlikely take more than 12 psi. Tuning is the key.... and yes it can be done on stock block.....

weak_sauce · 11-21-2005, 05:58 PM

well with the greddy kit, ctr cams, blox IM, and hondata tuned, i was hoping to push at least 300whp or more with the greddy kit, but if i cant then im going to go with the t3/t4 turbos..keep in mind its going to be tuned...

I understand, but I think you missed my point (which I should have been more clear about from the start); you didn't see me reply that I have seen those on a greddy kit without higher psi numbers did you? No...the 18g is a capable turbo and many dsm guys run them, but I find that the greddy kit itself has a few hold backs...more than just its tuning. Here's a gsr tuned at 14psi on hondata still not 300whp off the 18g:

It's possible to get 300whp, but I myself prefer a larger turbo to get me there.
I ran a small turbo on my b16a (small t3), at the time it seemed ok. I was of course comparing my stock b16a turbo with my old set-up which was a d15b7 and the same turbo. The b16a felt so much better, more power and lots of revs. I swapped that turbo (on my b16) out for a larger t3t40E, it was a night and day difference...Not only did I make about 25whp more I did it on 1 psi less of boost pressure (9psi vs 10psi)...
You can do it with that turbo, but IMO it will be easier to do so with a larger turbo.
How far do you "plan" to take the car (hp wise)...if your planning on about 300whp and stopping then maybe that turbo will still work for you. If you think that you'll want more power down the road then maybe you should look into a larger turbo to get you there.
My original goal was for about 250whp and then stopping....well I wanted more so I bought a larger turbo (.57 trim .63 a/r t3t4)..it will work for my initial power plans (450whp) but I'll once again be swappping it out for a larger turbo capable of 600whp or so.....it never ends.....

I was going to do some searching for some dyno sheets on another site for you, but looks like you've already posted there..

...as soon as the search is back up you should be able to find some dyno graphs...I remember seeing some 300+whp graphs and I believe the boost was around 16psi or so....

unless your point is
A: 300whp is possible on the stock motor (we both agree)
or
B: the 18g is capable of 300whp (which we still both agree on)
I don't understand your point then....??

Maybe i'm just being retarded, but what was your point to my post?
Take me back a step or two so I can understand

if you have too.

I was rushing to finish a water treatment design when i replied so it was very unclear as I read back over it...what I was trying to get across not so much to you, but the others reading, is that the larger turbo kits hit those daily stock and safely, but the greddy kits need to be worked much harder to get to that point. It's very hard to get the greddy kits up there the way they come from the factory (given tuning changes of course)...yes it has been done, but not nearly as often as a kit with a larger turbo. The original poster seemed unsure of where he wanted to head in terms of the kit, and the simple fact is that the greddy kit isn't the most well designed for performance...it is designed to give added hp while still remaining street legal (something I think costs it the capability of hitting higher numbers without custom work).
