Well i completed installing my turbo kit and it really sucks. My little d16z6 can barley spool the t3/t4e .50, .63 a/r i have, and its also clipped. Its slower than when i had the t25 in. I get full boost at about 5.5k. My power band just sucks. I cant even spin the tires. Well my setup consists of 8.5 srp pistons, eagle rods, block guard, diy log manifold, and a revhard ic w/2.5 ic piping. My question is how do i make most of what i have?

get a smaller turbo.

 

big turbo + low compression + little motor = the title of thread.

 

sorry this is a little ot... but does anyone know if that turbo is a good setup for a b18b LS motor? would it be too big?

Exactly... A T4 compressor wheel is a poor match for almost any low displacement engine. Try the common (and maybe cliche) T3 compressor wheel with a T04 turbine wheel

Most likely too big... Later (when I stop being lazy) I'll do a compressor match for that compressor and the B18B and post it up

 

higher compression or smaller turbo if u want a better powerband. see if anyone here wants to trade turbos with you? i dont know, just some suggestions. hope this helps.

 

Could i just get my head milled a bit to higher my compression or would that not be a good idea?

 

give me your turbo and I'll give you mine

 

Well heres a heads up for people wanting to trade turbos. It has about 25 miles on it, but it also leaks oil because i hooked to oil inlet and outlet wrong at first so i would assume it needs a rebuild now, and it also has an internal wastegate. I would be willing to help pay for part of the rebuild, so let me know if anyone's interested.

 

squeez to spool the turbo

 

I'll strait up trade you for mine Mine is worthless. And it wont fit your manifold.

Save up some money and buy a small t3/t4 and get your manifold redone with a new flange
Sounds like you got all the hard stuff done already from your mod list. Don't dispair, you're almost there!

 

Or u can get NAWZZ to spool it not that u want to ..

 

Would my blow seals contribute to the massive lagg i get??

 

Yes

Cheapest solution: 50-shot with a Hobbs Turbo/Nitrous Switch to turn on/off the NAAAAWZ at a certain boost pressure.

 

squeeze on that thing....

but seriously... make sure the turbo is good that might be yoru problem.... or at least part of it.

 

a crx i know of w/a d16 has a t3/t4 and that ****** ran a 12.5, but he has smaller housing, soooooo get smaller housing it will spool, you have a d16 for crying out loud it doesn't spit that much exhaust

 

OUCH! a straight T4 on a D16 with 8:5 compression! I would get a T3/T4, i have an LS and i wouldnt even run a straight T4 on it. Currently i use a T3/60-1 on my stock LS and it makes full boost at 5200 RPM. It is a similar powerband to yours it sounds, but mine definatley spins wheels and it isnt that bad going from T3/T4, the top end gain is worth the lag in my eyes.

you wouldn't happen to be talking about lawrence's car are you? if not just a coincidence cuz I know a guy with that same setup running the same time.

 

that depends who is this

 

lol didn't anybody notice this man is completely wrong?!! Boost Blows Vacuum sux

Has anybody else seen the compressor map for a garret GT-28? Perfect for 2.0's if u ask me. expensive though

 

I think im going to get it rebuilt first and start from there.
