okay so what would everyone suggest i do as far as head work to handle 315 whp?

 

stock head porting is fine. don't waste money on stupid stuff.

 

as far as engine work goes i've decided on doing titanium springs and retainers, headgasket and headstuds. should be able to handle 320 whp?

anyone have a link to where i could buy manifold with a T2 flange?

 

your stock head would hold even past 400 hp,my stock b16 head will go over 400hp and be fine... i have searched for a t25 flange manifold before and didnt find one because people arent going to waste their time making a pre-fabbed manifold ready to go for a turbo that isnt widely used external wg and its mainly a dsm flange, best bet would be to contact a fab company ie; spoolin performance, rcautoworks, straight line specialties, etc.

 

okay maybe i could get the local speedshop i go through to make one up. how bad is the cast manifold anyways? i've heard that you can gain a good 20 HP just by going to higher flow manifold.

 

well from what i saw on my greddy manifold it was the worst flowing thing i have ever seen, if i remember correctly i think the #2 cylinder hole on the manifold where is flows to the divider in the manifold is like an inch smaller than the #1 cycliner hole lol, the only thing i changed on my new dyno to get 55 more hp was the manifold, 3" downpipe, external wg, and i put a 70mm throttle body on there so yea i would say upgrading manifold makes a huge difference...but tell you the truth if i were you i would just sell the greddy turbo and manifold and get a t3/t4 turbo and your life will be a lot easier than trying to figure this greddy turbo out, the only reason i stuck with the 18g is because i wanted to prove what that turbo is capable of, but it made things so much harder than just doing a regular t3t4 setup

 

the turbo is in perfect shape and i wanna see what i can get out of it first. if it's enough for my needs then perfect. if it's not enough power i'll get a new turbo. when you order a garrett turbo does it include oil lines to or gotta buy those seperate?

 

yea i understand where your comming from, it is capable of your power goals but at just a little higher psi than other turbos but i think you will be happy with it cause i am more than happy with mine...i think you have to order lines separate but im not 100% sure, if you need any help on figuring your setup out with that turbo just hit me up on here

 

ya it should be alright for my power goals. random question, are you running an LSD? and do b16 trannies come stock with an LSD? i've heard some trannies do but i was just curious if the b16 trannies do come with one.

 

i am running a ls tranny with a open diff., the only b16 tranny that comes with lsd is a jdm one

 

what shop did you go to, to get that setup built its pretty sick. i also hear your car runs low 14's with that setup. is it cause you dont know how to drive?

ahh i got a couple of cheep guys off the street to do it all in my garage, nah i run high 15's with slicks, i just rev up as high as i can and dump the clutch and do a burnout down the whole track lol, you must have seen some other crx running that quick lol, wow congrats on your first post miguel!!! cant believe you finally figured out how to post haha

 

Do not waste your time modifying the 18g. Just sell it and get yourself a 57 or 60 trim t3t4 and you have a much easier time. I made 345 whp on the 18g with the greddy manifold modded for 38mm wg. It was good but I should have just went to the setup I have now for all the time and money wasted.

 

for how much i'd get for the 18g and how much more it would be for a new turbo and wastegate and manifold no. i'll get a new manifold made for couple hundred and get 350 whp out of it and be happy for now. like i said my goals are only 315 whp and the 18g can do up to 350 whp roughly. if i decide i want more power then i'll sell it all and get a bigger turbo.

 

i have had a 18g on two of my cars and am planning on putting it on the third one now. I absolutly love the turbo.. i havnt driven much of cars with other turbos But i mean i would suggest you try the 18g since its perfect for a street powerband. You dont have to rev high to get the power and gives you pretty good torque numbers. Not much turbo lag.

 

exactly. i'm only looking for 315- 350 whp. the 18g should be able to do all way up to 350 or close to. if i want more power then i'll get a bigger turbo. already purchased the 18g may as well put it to use.

Fine but that internal wastegate will not take you there with any measure of safety. You will see boost spike upwards of 22-23psi to be able to run 17pounds. 17psi should get you about 315ish. Good luck

 

well the guys at speedshop that i go through said it should be fine. i told them if i'm at 16 psi with 300 WHP and it spikes to over 20 psi they're buying me an external wastegate. so i'm really not worried if the internal holds or not. if it does great, if not well i just got a free external wastegate. has anyone ran 315 whp on a stock b16 tranny with no lsd? if so how bad is traction?

This is partially incorrect. Though a DSM uses a T25 turbocharger, it does not use a T25 flange, it uses a 7cm^2 radius flange.

 

are you going to use a stock bottom end? b16? if so i wouldnt boost past 17-18 psi and what engine management are you going to use?

my bad...maybe its nissan im thinking of???

 

i'm gonna be running about 16-17 psi roughly. whatever it takes to get 315 whp. i haven't seen many 400 WHP builds that have built bottom ends...

i thought the bottom end on b16's are rock solid and can handle?

if your set on that turbo i would definetly go with an external. that speedshop might buy you an external if it spikes but are they going to buy a new motor or turbo if they blow from spiking that high? just my thoughts.

 

i wouldnt say they are rock solid, but i set my boost cut at 18lbs just to be safe, i honestly dont think you will hit 16-17lbs on the dyno cause i didnt even get that high with the external wg, you will probably see 16 for a second because of spike and end up at like 14lbs

 

the motor is in great condition. i did compression test before i pulled motor to do some head work and it was within 3 psi across all cylinders. i'm using hondata so therefore it won't let it spike to 20 psi+.

i've known these guys for a long time and if they say they will buy me an external wastegate they will. but i'm gonna push the internal as far as it will go and see what we can get. i'm most likely just gonna get the car to go just over 300 WHP cause it doesn't look like i'll be getting an LSD right away. my budget didn't incorpirate an LSD
