BlinD's 93 R1 Build
 
Figured it was time to post a build thread, so here we go...

Picked up the car a few months ago and since then have started to fix up stuff back to OE condition and mod as I go.

Mods when I took delivery of the car:
- Apexi Power FC w/ Commander
- Pinned non-sequential
- Supra Fuel Pump
- GReddy Profec B 'tuned' to ~15psi (stock SMIC) :icon_tdow
- GReddy Turbo Timer
- GReddy downpipe with custom catless midpipe
- Unknown short shifter
- RacingBeat front swaybar connector
- Tokico 5 way adjustable shocks w/ the R1 springs

Mods I've done so far:
- Interior cleanup (plastidip spray to give '94+' look)
- Pettit steering wheel gauge shroud w/ Boost Gauge
- Custom engine torque damper Click here for my how-to thread
- 99' spec tails
- Misc interior/exterior parts replacement back to OE

Pics of the car when I first got it:

http://i6.photobucket.com/albums/y21...7/IMG_0272.jpg

Not two weeks later I took the car out to a meet and had a racoon dive bomb into the car:
http://i6.photobucket.com/albums/y21...7/IMG_0286.jpg
Most of the damage was superficial and just hurt my wallet in replacement parts

All fixed up and out for a little shoot (more pics in the 'Post your FD thread') :
http://i6.photobucket.com/albums/y21...9/IMG_3716.jpg

After doing some research I decided what direction to go with an intercooler since I wasn't fond of the idea of running that ammount of boost through the stocker. I decided on the GReddy SMIC w/ hardpipe kit. After tearing into the car to do the install I found alot of 'shortcuts' in the non-sequential conversion and decided to clean that up and do some other mods at the same time.

Mods on the agenda:
- Banzai Racing 9 piece Block-Off plates (Remove the studs by double-nutting them and replace with provided bolts w/ some locktite.)
- Pineapple Racing Idler Pulley kit
- Efini Y-pipe
- GReddy SMIC w/ Hardpipes

Damn sexy. Love Black on black R1. Love the plate too. Looks like she's on the right track to good care. Is that the idler pulley for more belt contact to the waterpump? G

BlinD26 09-30-09 02:12 PM

Exactly. I've read too much negative things about deleting the airpump and soley relying on a larger diameter pulley w/ shorter belt.

Figured the cost wasn't that much more for the Pineapple Racing kit vs a GReddy pulley set or comperable.

The good thing is later on I can go to the larger diameter waterpump pulley to aleviate cavitation and still have a 'stock' contact patch.

EviLPeNeviL 09-30-09 02:19 PM

Awesome work, do you have any shots of the interior all done and put back together? Want to see what the outcome looks like.

themcneal 09-30-09 02:57 PM

Great work, thanks for posting pics.

BlinD26 09-30-09 02:58 PM

I will try to get some pics this weekend when the car is moving. It's almost impossible to get good interior shots in the garage due to lighting.

mrb63083 09-30-09 03:00 PM

Looking good!

Was it a pain to remove that rear turbo pipe?

At first I thought it was going to be and had all sorts of different sized extensions and flex joints on hand but it wound up being pretty straightforward with the car jacked up. I'm sure an aftermarket DP helps since you have a bit more room to work around.

I haven't reinstalled the pipe yet, so might be interesting getting a torque wrentch up there :lol:

mrb63083 09-30-09 03:30 PM

Yeah, I'm going to take mine off to have it ceramic coated. Luckily I do have a 3" aftermarket down pipe, so that's relieving.

Do you have to torque those turbo pipe bolts back to spec?? They seem kinda small to put too much force on... as if the bolts/nuts would break with too much pressure. ???

BlinD26 09-30-09 03:32 PM

The y-pipe/charge pipe only get about ~96 inch lbs, which equates out to about 8 ft lbs.

Like you said, its not much, but anytime I'm dealing with gaskets I like to make sure its equal pressure around the surface.

BlinD26 09-30-09 03:43 PM

Cool thanks for the invite... My goal is to have the car up and running with the idle dialed back in by the weekend. If that goes as planned I may attend and might be able to convince my friend to come as well ;)

Gorgeous shot!

At first glance it looked like a CF hood, but after peeling my tiny Asian eyelids open I realized that it's just a shiny glare.

BlinD26 09-30-09 03:58 PM

Nope, you were right the first time.. I believe he has the CF Feed replica, not sure of the make though

mrb63083 09-30-09 04:01 PM

It's defiantly a FEED hood.

For the guys wondering how access is to the rear turbo inlet/charge pipe:

http://i6.photobucket.com/albums/y21...c/IMG_0466.jpg
http://i6.photobucket.com/albums/y21...c/IMG_0467.jpg

Now, onto the headache... When I was initially attempting to size/fit the GReddy SMIC I had some issues, but I wrote it off and decided to do all the other subsequent mods. When I attempted to revisit it tonight, this is what I was dealing with:

Using the GReddy 'cover' to align the SMIC, seemed to be getting me more in the ballpark of alignment then having the stock ducting in the way:
http://i6.photobucket.com/albums/y21...c/IMG_0468.jpg

Coolant hose bracket or no bracket, I couldn't get the SMIC bracket to line up:
http://i6.photobucket.com/albums/y21...c/IMG_0470.jpg

You can see the dust on the pulley from where the SMIC was making contact before I used the cover to align it:
http://i6.photobucket.com/albums/y21...c/IMG_0472.jpg

Now, onto the worst: Hard pipes:
http://i6.photobucket.com/albums/y21...c/IMG_0469.jpg
http://i6.photobucket.com/albums/y21...c/IMG_0473.jpg

How in the hell could this conceivably mount like this? Any engine movement at all would shred these pipes to pieces. Just the pipes touching when trying to size was making small aluminum shavings.

Currently I'm at a loss for what to do next. Any protips on mounting the GReddy SMIC?

smog-guy707 09-30-09 09:09 PM

wow... looks like this is coming along great! keep up the good work

haha looks good!!! the silver is more subtle. i'm sure they perform the same.

too bad i ran out of the stuff so i didn't quite make it to the tb.

BlinD26 10-01-09 08:17 AM

Bling bling goooooold ;)

Anyone have thoughts on the hardpipes? I did some digging and found some mention that the GReddy 2 piece kit 'may not fit with the GReddy SMIC and may need to be trimmed'.

Looks like I have about 1/2" on each end that could be cut off, but then I need to get a bead back on the pipe

Force13B 10-01-09 10:44 AM

That sucks! I had to make some custome brackets for my FMIC to fit right, i haven't had anything go smothly on this car :lol:

If you are not using the ducting that came with the SMIC will it fit?

BlinD26 10-01-09 10:54 AM

It was actually worse before when trying to use the stock ducting. Per GReddys instructions it tells you to trim only 1/4" of the plastic in the front off to make it flush, but it indexes the SMIC too far back and that's where the bottom inlet was rubbing against the crank pulley.

Now that I have some sort of reference using their duct I guess I can build around it. Looks like my local welder has the ability to roll pipe beads so I may just chop a bit off each end of the longer pipe to give some room for flex.

I'll keep you all posted.

Decent build thread.

mrb63083 10-02-09 02:11 PM

Thank you for the rear turbo pipe pictures!!!

Interesting about the coolant hose bracket. One would imagine Greddy would make a bracket to adapt to the stock engine bay parts. Personally, I think it's cool there is a bracket for the coolant hose. I guess you could drill a new hole?

Looking good!

kyle_94538 10-04-09 07:21 PM

Skip the Greddy duct, it's useless. I haven't had success using that for alignment either. I cut the stock duct down to the middle of the air inlet hole cutout (2+ inches), installed it back on the car & ensured that it aligned up with the a/c dryer, then bolted up the intercooler & did fabrication work around that. Remove the coolant hose bracket, bolt up the intercooler to the hole on the right.

lol with all this heat wrapping going on, we need to get afgmoto in this thread with his almost entirely gold wrapped engine bay

mdpalmer 10-05-09 09:19 AM

Hey man, looks great. Never seen the silver/gold foil on the UIM, that's a great idea. One thing I noticed after looking at your pics: if you're nonsequential, you can remove the pressure chamber (the black box that sits right in front of the UIM, has two vacuum lines coming out on the driver's side), precontrol/wastegate control solenoids (mounted as a pair on the UIM), and the metal vac rack that goes down towards the turbos where the actuators are. You can probably put them up for sale and make some money back too :) Also, you don't need any of the solenoids on the rats nest (unless you want to keep your pressure regulator control, you eliminated your ACV so the relief and switching solenoids can get tossed, your EGR was eliminated too), you can take the whole thing out (the metal rack, solenoids, etc. just cap off any open nipples on the intake mani). You'll end up with a bunch of unconnected harness connectors... you may want to wrap those up with some heat resistant tape. The branch of the harness that has all of the rack solenoid clips, you can tuck that behind your fuel lines (sit it on top of the tranny) if you want to open up the space under the UIM a little more... you can also remove the charge control valve (the BOV in the rear) and cap off that hole, it could be the source of a boost leak if it fails and you don't need it.

EDIT: I noticed that you have a Profec boost controller, if you have that controlling the wastegate you can eliminate the precontrol/wastegate control solenoids.

BlinD26 10-05-09 11:44 AM

Thanks for the tips mdpalmer, wasn't aware that most of that could be deleted.. I'll have to keep that in mind next time I remove the UIM...

Is the primary BOV enough on it's own to relieve all the pressure in the Y-pipe? They both seem to be functional so I don't see any harm in keeping them both.

Here's a writeup you can check out on full non-seq conversion: http://www.rotaryresurrection.com/3r...ov_nonseq.html The CRV is only there to allow pre-spooled secondary turbo boost pressure to vent, and you don't have the prespooling/sequential setup so don't need it. The vac signal to the CRV is controlled by the charge relief solenoid which you don't need either... Here's a good description of how the control system works if you're curious:

http://www.autosportracetech.com/RX-...erOverview.htm

As far as the primary BOV (aka air bypass valve, ABV, in mazda literature) being enough to relive pressure on its own, I haven't had a problem with mine yet. The real issue is that it doesn't leak under boost... if you're running 15 psi you may want to get an aftermarket one if you're paranoid. I don't think the stock one was designed to handle more than 14 psi with regular boosting, but that's a wild guess...

BlinD26 10-12-09 06:42 PM

Aaaand were back...

While hunting for a shop that had a bead roller dye large enough to do nearly 3" pipe I decided to continue with the thermal barrier and wrap the bottom of the IC that sits over the radiator and near the coolant hose:

http://i6.photobucket.com/albums/y21...c/IMG_0486.jpg
http://i6.photobucket.com/albums/y21...c/IMG_0489.jpg
http://i6.photobucket.com/albums/y21...c/IMG_0491.jpg

SMIC installed in it's modified location w/ modified air duct:
http://i6.photobucket.com/albums/y21...c/IMG_0492.jpg

Just how far off the SMIC was from the 'prefered' mount:
http://i6.photobucket.com/albums/y21...c/IMG_0493.jpg
http://i6.photobucket.com/albums/y21...c/IMG_0499.jpg

After talking to numerous shops that either wanted to weld a bead on the pipe or cut the ends off and reweld them on, I decided to just push forward and get the car moving again, so I devised a plan re-using the stock accordian piece with the included Trust elbow:
http://i6.photobucket.com/albums/y21...c/IMG_0494.jpg

More shots of the modified stock duct w/ the modified Greddy duct:
http://i6.photobucket.com/albums/y21...c/IMG_0495.jpg
http://i6.photobucket.com/albums/y21...c/IMG_0496.jpg
http://i6.photobucket.com/albums/y21...c/IMG_0497.jpg

In the end, the car went back together without too many hiccups and ran like a champ. Profect B showed peaks of 13.7 psi with the ultra-restrictive catback still on the car. I couldn't stand looking at the stock airbox anymore and got some flack for having it on, so I tossed on the ARC airbox, untill it sells of course ;)
http://i6.photobucket.com/albums/y21...c/IMG_0500.jpg

Next on the adjenda, HKS RS intakes and a free-flowing catback, then some dyno time.

Custom SMB exhaust showed up yesterday, and I'm super impressed. The welds on this thing are pretty epic for a one-off, they look better then most production welds I've seen.
Oh and thanks Fedex for showing up at 5pm and not letting me get tuned **shakes fist**

Now I have a true 3" system (GReddy downpipe, custom catless midpipe and SMB custom catback)

I don't mean to sound like an idiot, but what is the purpose of using heat tape underneath the Extension Manifold? Is there some kind of advantage, or does it prevent something from happening? :scratch:

In the Torque brace video, was someone playing with compressed air, or was that noise coming from the motor? Does anyone else hear that? Could that be a vacuum/boost leak?


Other than that, car sounds great!

Double_J 11-03-09 08:07 PM

I hear it too. Seems strange that the noise goes away with higher RPMs. Either that or the engine/exhaust is drowning out the hiss......
