Well right now i'm running a stock block D15B sohc vtec with a greddy turbo kit and I am planning for a way to make 300whp on a d series reliably. From what I know the 18G turbo will bolt right up to my current manifold with the 15G on it and with some new pistons and rods do you think this thing could see 300+ whp? Tuning is done on a hondata and the injectors will be 550s and a walbro 255lph fuel pump. For the block I plan to just find a D16Z6 block and have pistons and rods done. I really don't want to get sleeves because i'm not trying to spend THAT much money and I doubt stock sleeves wont hold up to 300 or so whp with a good tune. So my question really is am I heading in the right direction here as far as acheiving my goals without spending to much and using what I have as much as possible?

 

i'm building another z6 again and i'll be having the same basic setup.
the 18G will probably be pricey brand new but i'm guessing you're looking for an Si owner parting out his greddy kit. With that setup and right tuning you should be able to do it.

 

Anyone seen any D series pull 350hp with this turbo?

 

The 18g is capable of over 350 whp.

Whether or not you make it just depends on the rest of your setup.

Edit: By the way, if you want to make 300 whp on pump gas you'll probably want more then 550's.

 

Hmm so I guess my setup should be able to do this with larger injectors. I don't plan to have this complete until next yeara since I just did a turbo setup on the stock block. 18G is a good choice for me because I can keep my manifold and just have a block built, switch the turbo, add larger injectors and get it re-tuned.

 

it would be a great choice...if it bolted up, which it doesn't

why?

 

You sure? I was told the 18G will work fine on my manifold that my 15G is on from my greddy kit.

 

Bump....anyone know for sure if the 18G will bolt up to the manifold that holds the 15G on the 92-95 greddy kits?

 

TTT...still need this info please

 

no it will not bolt up, you were told wrong

 

good luck, the 18g didn't really get me near 350whp. that's just insane, if your going to get piston/rods combo, just do it right the first time and try something a little bigger then the tdo5. around 14 psi, you will run into boost spikes from the internal wastegate.

270whp is something i would expect to yeild with that turbo/set up.

jus my .02 cause i've been there.

A 14b is capable of about 300 whp. It's been done on a DSM, and if it hasn't been done on a Honda yet we will do it soon.

As such, there is no reason you should have a problem with 350 whp with an 18g.

You just need to learn to push the limits a little, I think.

 

There's a GSR with a Greddy kit that made 331whp on 12 psi over on the AEM forums. However he did upgrade his downpipe to a 3 inch.

 

So I will need a whole new kit basically if I want a bigger turbo?

 

You could try getting a 20g but I'm not sure about the flange compatibility. But other than that you would have to get a new manifold, turbo and downpipe.

 

you can get an adapter plate for the manifld.
