true

So last year I thought I was finished, but I've never really been 100% comfortable with my turbo configuration -- until now. I am confident this will finally be the smooth, reliable, powerful, raw turbo Honda I've always wanted. I think this is the 5th and final turbo reconfiguration. Some pics of past configurations:

1st config -- late 90's?



2nd config




3nd config


4rth config (last years)


Now the final setup I am using is Full-race Manifold/dp -- everything else custom. Of course everyone who works on turbo CRX's is that nothing fits and everything needs to be hacked to fit. I have done all of the work in my garage by myself. Just how I like it.

Pictures of the Manifold quality:


For anyone wondering what it takes to use a FR manifold/dp with a Civic size aluminum radiator should check these out:
Rough outline of what needs to be cut

After cutout -- still needs a little cleanup:


It's possible the radiator will fit without sloting the engine bay area there, but the clearence is rediculous without doing that.

Next, the FR is really meant to use a -backdoor- intercooler setup, but I still wanted to use my old IC so I made my custom backdoor:

Hook up the supertrick shopvac on reverse to keep all metal shavings out the IC. Works great.

I just used a hacksaw, it worked well enough.

Toast:

I used a 2" holesaw to cut the new hole after mocking up and aligning perfectly.

Here is the new coupler mounted, and the greddy TypeS was just welded directly to the old endtank outlet.

I also put a wastegate reference point on the IC endtank. Referencing from the intake manifold can sometimes allow creep or overboost when really rompin on a hot setup because the turbo can stuff a lot of air before the signal transfers back to the gate. Putting the nipple on the turbo (like most do) is probably safer then the IM, but I don't want to reference before the pressure drop -- I want to regulate true boost pressure. I feel this is the happy medium for both which should give good throttle responce, and accurate readings:


Finished DIY backdoor:


I have went at with Geoff before regarding placement of the BOV on the endtank. My stance was that basically no matter where you put it on the Chargepipe, it most likely would not be noticable by any human. I do, however, fully support it because of the fact that it is not wasting cooled air. If we all like turbo's because of their efficient use of wasted exhaust energy -- it doesn't make much sense to relief pressure in the intake tube that has already taken the pressure drop and been cooled. In the case of the BOV on the other side, it would be very likely you will waste already cooled chargeair, and have to do double work to get that air replaced. It probably still doesn't make much of a human noticable difference, but that was one of my justifications. It worked out well though, I must admit.

The new backdoor setup fit is almost precision. The angle on the turbo is because the Full-Race flange is slightly twisted, there was nothing I could do it make it parrellel. The IC is dead-nuts level in both directions. I also have plans on making on slightly angle inward plate on the top and the bottom of the IC to help IC efficiency \__/ That would be the view of the top of the IC on it's back.




For any CRXer wondering what it takes to run a full-race and a 46mm Tial wastegate, look at this:


Not the prettiest hack, but totally acceptable.

My drain line is probably the thing I'm most unhappy with. Yes, I know it's attached on the lower port, but I am confident it will drain fine as the turbo drain is still lower then the oil level that will be seaked in the drain tube. The JimFab crossmember REALLY interferes, this was about the ONLY thing I could do:

It's fully downhill, and there is more clearence then there looks, but the only other option will be to weld a new bung diagnally on the top of the pan. I may do this depending if I run into any drain problems.

Pictures of the parts falling into place. I'm using civic C & R radiator


The dumptube is tough as nails..I am going to be running a .3 bar spring in my wastegate so I need to be able to waste tons of exhaust energy. This thing looks like my downpipe, but it IS my wastegate dump.

I grinded some spacers so there was clearence for the weld. Pretty good trick, it worked perfectly. I didn't want to heat up and bend in the pipe like some do. Just another idea.


I don't have a tig welder so I hacked up various aluminum pipes I had and made my chargepipe. (that's why there are so many couplers) I will get the blue sections welded at some point as the surfaces are all touching and designed to be welded soon.


These are ATP turbo hump couplers. These couplers are awesome..gives tons of vibration control and just easy to work with.


Picture of my dumptube hugging the 3" downpipe:



Coupled up:


With the radiator and custom radiator mounting brackets in place:



Radiator and dumptube clearence is great. It looks closer then it is especially with the heat wrap:


Some final over-view shots:




and finally:



The engine is the same configuration as last year..some specs:

b18c5 block w/ typeR crank
84.5mm Darton closed deck

8.94:1 JE pistons
Crower Rods
TypeR head with Crower Dual valve springs
GSR cams (soon to be ITR intake cam)
RC 660CC injectors
RPS turboclutch
Gator Racing stage 3 axles
Fastbrakes front upgrade kit
Tien HA EG coilovers
Full-race manifold/dp
custom IC piping
custom 3" exhaust
Hondata with OBD1 converson P28 s200
C&R radiator
Tial 46mm wastegate
t3 .63 stage 3/ 04e 57 trim .60 a/r Garrett
Moroso oil pan
JimFab crossmember
Moroso catch can and radiator overflow
YS1 LS cable transmission with ITR 3rd, and 4th gears
Quaife LSD
HASport mounts
B&M FPR
AEM fuel rail
PLX Devices m200 wideband
Greddy TypeS
Cometic 85mm headgasket

There is tons of other stuff I just can't think of right now. I will update the thread when I toss the bumper and and wash it up. The engine should run about the same as last year -- just need some fine tuning. Don't ask about HP numbers, I have not dynoed it, and could really care less. I built this car to be my reliable street beast. It has had nothing other then 100% street tuning, and last year before I pulled all the turbo confiug, it was tuned perfectly, and ran exactly like an OEM turbo car. (minus the Hondata 600mb hickup -- really looking forward to that fix)

Very Nice

How long did this last build up take you to complete?

HaTcH_BmX

WOW !! talked about pictures !!

nice set-up !!

Aint that the ****** truth...

AbaZ

Everything is sexy.. but I dont like how your oil return goes under the cross member and goes back into the bottom of the pan. I try to keep my oil returns at the top of the pan.

.nate

daaaamn thats badass!

Full-Race Javier

looks good...should be a fast car

nevin

You forgot the pics of the hood webbing you have to cut out for the hood to close or have you not tried to close it yet? Also I saw you cut the bumper support, what is going to hold the bumper on?

FOrSfEd

Pics look great. Nice set up

CRX T-Si

STOP this thing.

I can't look nomore.

**** is making me Jealous.

So much stuff that I don't have .

U should thing about welding up the IC pipe so you don't have to use so many Silicon connectors.

WOW! That's looks so amazing! Makes me feel behind because I just put on my CRX what you had in the late 90's. hehe.

714phil

how is the clearance of FR's 3" dp and the ground? looks good... hurry up and post pics with the bumper on.

turbo_ef9

aren't u worried that with the movement of the motor, that the coupling holding the ic and the turbo might come off? why not use one of those hump ones for that section? anyways.. it looks good.. with it having no upper support looks dangerous

Full-Race Geoff

true -- the setup looks good, great sereis of evolution pics!

btw i definately STRONGLY recommend not running your oil return line there, it will blow the turbo seals and compromise oil consumption.

Full-Race Geoff

here are a few more crx clearance pics. very little hacking needed.

japrex

Damn that fucken nutz man. you really know what you're doing. great job. i live in midwest area and am now going to UTI in chicago. i have a turbo crx im building right now. i will probably drop you an email.

Carlito Brigante

moment of silence....
realease the air slowly..

Wwwwwoooooooooooowwwwwwwwwwwwwwwwwwwwwww

that setup is by far one of the best ive seen....
good luck with that. looks like mad hard work and money invested.

ScottEK

It's inspiring to see someone who had to cut up there CRX more than me, when it comes to getting boost I'm ready to cut off anything standing in it's way.

Jays91DXhatch

Everything looks damn sweet!

If there were 2 things to change, and as it's been mentioned, it would be:

-oil drain, put on a angled fitting at the top of the pan like you mention, rather do that now then replace the seals on the turbo

-Get that darn charge pipe welded dude! You have like 200$ of hump hose and couplers there...lol sell that ish and pay to get it welded!

That's a great setup. I tried turbocharging my crx and after doing few things I gave up. I ended up turbocharging eg. It was lot easier

Jflex

dam mang, nice work!

You'll never be done...thats' how it is

looks exactly like my old setup... less than an inch between wg and ic. DO NOT launch the car in reverse.

TRE_

awesome setup man... its cool to see how you fabricated some of your own stuff to make it all fit.

FR's manifold is so sexy... nice work on the IC too!

red cx

nice man very nice.
