Re: Turbo build advice for B18C
this forum is all opinions man, im a if it aint broke dont fix it kinda guy. if your stage one is healthy and your torque numbers are gonna stay around 200 then u might as well just leave it until its shot and in need of replacement, then feel free to buy whatever clutch u want. right now u need to focus on the turbo kit and tuning once the car is boosted then u can make a new list of all the shortcomings in other areas. like brakes and clutch for example.

stage 1 is going to drive better than any of the race clutches. if you haven't killed it, leave it

Re: Turbo build advice for B18C
So I've decided on an entry level, low boost setup. The Greddy 18G. It seems reliable and makes acceptable power. I found someone selling the turbo, manifold, and downpipe for an unreal price. I had to grab it.
Now because it is internally gated, do I still have to use a boost controller? At what PSI are these set at?

Re: Turbo build advice for B18C
i would weld the internal closed and use an external with a mbc but thats just my opinion, i know nothing about the greddy 18G maybe someone else can chime in here.
where did u get your itr brake conversion from?

The wastegate actuator from GReddy's 18G is about 6psi. It can go to about 13psi at maximum, but that's when the flapper door and opening become a problem and you'll experience some spiking when going to the upper level. The actuator can only take about 2 times its spring rate no matter what you do to it (Shortening the actuator rod, or using a boost controller of any kind.
Most people will get an aftermarket actuator for the turbocharger when approaching the 300-320whp range. The restriction is the downpipe that comes with the kit (a scant 2"), and the downpipe adapter elbow needs to be ported in order to work, or it can be eliminated and a custom downpipe can be made since the turbine flange used on this turbo is shared with the GT28RS 5 bolt.
If you got it for an "unreal price", this means that either he didn't know what he had, and had difficulty selling it, or had issues with repair, as a lot of people nowadays are not replacing the wheels and internal parts (which are still mitsubishi and have increased by over 300% in the last year alone). So be aware of the fact that you may have to repair this turbocharger in the process. Its just a nature of the beast. There are repairs and upgrades available,but they are costly and don't necessarily warrant their purchase, but that will be for you to decide if there is, in fact, an issue with the one you're considering.
I had several of those turbochargers years ago and they were very robust; provided that the owners took care of them while in their possession. They will make the power you need, but be prepared to do some modifications if you don't get the results you'd like. There's an entire thread on the GReddy 18G that is on H-T, but use the google search to find these particular threads.

Re: Turbo build advice for B18C
^^Man I don't know what you do but it sounds like you save lives and wallets lol! I was just reading a thread from a few years back about spark plugs. I'm wanting to do a mild tune up before this car hits the ground again. Would it hurt to install 1 step colder plugs (7) without the turbo and leave it gapped at 1.1mm until it's time to turbo and tune?
The price of the manifold, turbo, and down pipe came out to $430 shipped. To me, that's unreal as I've been coming across turbo's that are $700+ alone lol. But the turbo looks to be in good shape, the guy is just parting out his setup. I won't know for certain until I get the thing in my hands.
Ideally, I want to go for about 9-10psi on this stock engine. I think that sounds safe and I don't have a clue how I came up with that number. You mentioned it would do 6psi, can this be altered with the installation of a boost controller?

DO NOT put in 1 step colder plugs until its time to turbo. you're not doing yourself any favors doing this Early. They're just plugs.. wait for the installation and tune

Re: Turbo build advice for B18C
^^Awesome thanks. Looks like I have a list of what I need to do and get thanks to you all! I've started running oil feed lines, vacuum hoses, got boost, oil temp, and oil pressure gauges, mocking up the FMIC and piping which is another world of trial and error lol. I'll start posting pictures up soon!

Re: Turbo build advice for B18C
Oh I forget the fuel pump is installed as well. One more question before it starts getting real; Whats a good manual boost controller? Are $10 units just as good as $80 units when it comes to manual controllers and is it better installed in the bay or the cabin?

Re: Turbo build advice for B18C
I was thinking about using this, but the 10psi version

Apparently, HKS uses them too.

I know people like to put together their homemade ball & spring controllers (I did those, and depending upon how much you wanted to mess with a choice of parts, its either horribly mickey mouse or its So-so). I blew up a couple motors with a homemade one years ago.
I like the Hallman Pro Boost controller. It's inexpensive, works hard, and the things never break. A lot of the big DSM and Evolution guys used these for over 30-31psi of boost pressure for years, so I'm familiar as to how they work.
A lot of quality for this boost controller. Here's also a video on it

You can find them relatively easily..

Re: Turbo build advice for B18C
I just did a compression test to make sure the car is in good health before I boost. I thought it was a good idea. I cranked the car for 8 seconds throttle open on all cylinders. The results were awesome. 210-220 from all 4! And I started the car with the oil pressure gauge. At cold idle the pressure was nearly 75psi @2.5K RPM's, and steadily dropped with the RPM's as the car got warmer. Checked all oil fittings for leaks, none so far. I think it's safe to say that I can boost!
Here's a couple of pics of the car but they're not so current...
When she was rolling
Installing new stealth alarm
Wiring was fun. Awesome learning experience
Her latest shot. Still on stands, no suspension at all. And really dusty.
The daily for now. Gas sucks! Yes, it's my lifted Trailblazer!

Re: Turbo build advice for B18C
I've got the turbo setup in today!
I'm trying to separate it from the manifold but those bolts are in some odd positions lol. I'm trying to also rotate it so I can access bolts and take off the ugly oil return line. I've loosened and taken off the VBand but it won't wiggle. I do not want to try to fight it either. Seems seized with rust or something.
Also, there's a dent on the waste gate as seen in one of these pictures. Will that affect it's performance at all? I can move the shaft by hand and don't really notice any binding.

Re: Turbo build advice for B18C
I got around to taking to taking off the turbine housing. These are the results
There's very little side to side shaft play, but it the wheels don't hit either housing. I think these pictures looks awesome and there doesn't seem to be any oil leaks or bent blades. There seems to be a cut blade on there, maybe for balancing?
I haven't taken apart the compressor side yet but I can tell you that it does have black, semi-wet residue when looking into the compressor housing. Could this be oil, a sign of a blown seal?

Re: Turbo build advice for B18C
After almost 2 years later.....
ARP Headstuds
New OEM gaskets, seals, and water pump
Changing oil to Valvoline Racing oil (black bottle with blue checkered flags)
Go-Autworks FMIC and Charge Pipe Kit
550cc saturated injectors Bosch EV14 Saturated
Samco radiator hoses
Moroso 5.5qt oil pan
Mocal sandwhich plate with t-stat
Setrab oil cooler
Open breather setup
2.25 downpipe (kept stock greddy elbow, untouched)
3an Line for oil feed
10 an line for oil return
Blue NGK Spark Plug wire set
NGK BKRE7 (something like that plugs) Gapped to .028
OBD1 P72 ECU
Hondata S300v3
Greddy Type FV Blow off Valve
Golden Eagle Vacuum manifold
FAL Fan for B series radiator in Civic
Koyorad racing radiator w/1.3 bar cap
Gates Racing T-Stat
HASport track mounts
Wow I didn't realize how much work and parts I put into this thing lol. Since the initial start of this thread, I picked up a 1993 Acura Integra LS for a daily and got that running like new after 1200 bucks worth of suspension components lol.
So I'm going to fire her up sooner than later after all the listed modifications. The car has not been started since I pulled the head which was about the same time this thread was started. She's full of fluids and only has been turned by hand at this point. But before I really turn her over, I have some questions that you guys might be able to answer...
1) What changes to hondata should I make to accommodate the parts that will give me a base tune to drive to Church Automotive for a tune?
2) Should I crank her with ECU fuse pulled a few times before firing?
3) Kind of getting my hopes up to around 220HP at 9Lbs of boost with this very mild setup. Do you think I'll get there?
4) How fun is this thing going to be?!

Not much you really can do. Just make sure that everything is hooked up properly, no leaks (fluid or exhaust) and get to the dyno.
2) Should I crank her with ECU fuse pulled a few times before firing?
Yep. That's so that you can prime the turbo with oil so that the bearings are lubricated at startup. Even just the Fuel pump being disconnected would work.
3) Kind of getting my hopes up to around 220HP at 9Lbs of boost with this very mild setup. Do you think I'll get there?
you could have done that with a bone stock engine , radiator. We made over 260whp on the stock adapter housing to downpipe.. This was back in '01. So, you're plenty fine.
4) How fun is this thing going to be?!
You'll know once its tuned. no one can answer that. That's like asking if going on a roller coaster is going to be great. you either A) throw up on the ride, and its awful, or B) have a great thrill more than you imagined. Its the same wait in line either way.... The only way to know is to find out for yourself
