my turbo'd 6 port, first drive
Alright, finally got my damn exhaust leaks taken care of, wastegate installed (didn't have to even notch my frame, woohoo), and running. Alright, here's the setup.
'87 Sport w/6 port engine (duh)
S5 turbo/manifold
Starion FMIC
Walbro 255lph fuel pump
550 primary/720 secondary
Home depot boost controller (at roughly 8psi)
I don't have pictures at the moment, batteries are dead.
Installation:
This was a pain in the ***. Sadly the flange I purchased from racing beat was warped, and nearly 1/8th" off on each end! Yikes! I didn't happen to realize this until it was all welded up and ready to install, so I had to spend an extra 3 days flattening it out, waiting for new gaskets/etc. Other than that, the only hard part is getting to all the bolts, with the turbo it surely cramps the space! I kept my K2RD ACV block-off with a bolt in the same place (however both were ground down considerably to make clearance for the Turbo, as well as the turbo's compressor bracket) All in all, it wasn't too hard to mount and fit it in, the hardest part came from running all the damn IC piping. Anyway, past that, what everybody wants to know...
Driving impression/improvements:
Well, I must say my first impression of when the boost hit was surely 'wow'. I'm currently only boosting to 6psi (don't have the MBC set yet), and even at that it feels about 2x faster than before. Just the kick you in your seat and make you hold on for dear life feeling was enough for me.
Alright, now for some numbers. For those of you concerned with grenading your rear-end or blowing your tranny into peices with the stock clutch, good luck. My clutch gives out at 4000rpm, and slips the rest of the way through the rpm range. However, for those of you interested in knowing the gain from before and after (even with the slipping clutch) Here are some g-tech numbers
Before (weight, 3000lbs w/ two passengers), result: 142rwhp
After(weight, 3150lb w/two passengers): 180rwhp
also, as a note, during this 'test' 180rwhp was obtained in 2nd gear around 4300rpm, at which point the clutch gave out and would no longer grip to provide a better reading. Once I get the new clutch in I'll be taking it to a dyno for real numbers, but the gtech with the weight correct is pretty accurate at gauging before and after effect, and let me tell you, you can surely feel it in the *** dyno. Sorry for the rant, just kind of excited and happy that after 3 weeks of bloody knuckles it's all finished!

I did, for about all of the 10 seconds the clutch held up, hehe. I'll be posting some pictures tomorrow once i can get some batteries. It's funny at how ugly the car looks, and yet what it's packing under the hood. Definate sleeper. :-D

Excellent news and work SonicRaT! I look forward to seeing some pictures.
Have you driven any stock or modded TII's before? How does your car compare, specifically in the lower-mid RPMS.

Oh, some other goodies:
Greddy Type S bov
Techedge wideband diy v2a
2.5" downpipe -> 2.5" resonator -> 2.5" piping all the way back to dual bomz evo (the same setup i had on the N/A)
home depot style TID (it's pretty ghetto to look at, but so is most the entire car, so nothing big there)
Also, i tapped the oil feed on the oil pedistal (1/8th -> 90 degree elbow with 1/4th nipple) running high pressure rubber hose to the turbo. It's holding up great so far. Other than that it was pretty much straightforward. Oh, ratcheting wrenches are you friend in this conversion!

sounds awesome james! BTW the tranny is holding up good-- it took a couple months after it got here to source ther ight parts. Some ignorany ebayer sold the wrong flywheel, and then some ignorant rx7clubber sold the wrong flywheel, finaly a month later i got everything lined up and installed
hope everythign works out on your end

Congrats SonicRaT!!
I understand the feeling of a boosted high comp rotor all too well!
just be careful of that rubber oil line going to the turbo..
I hope its actually silicone not rubber, my rubber one did not last long at all , split right near the CHRA..
So I went to stainless briad... Just something too keep in mind..

You mentioned not noticing the flange was warped until after the welding. This almost certainly due to the welding itself. I would be EXTREMELY surprised if they actually sold a piece of flat plate that was off by that much. Welding on the other hand will do that quite easily.
Good job on the car, enjoy it.

Congratulations on the swap. Have fun.

It's good to hear that a turbo NA is not as bad as a turbo tII. I wonder how a centrifugal supercharged NA drives . . . .

Towards $150FC, yeah, engine was just rebuilt around 700 miles ago and compression was 115/118, turbo can't be verified. No matter what I did I could never see full boost in that car until late in the band (around 4000-4300rpm), and it's the only other turbo rx7 I can compare to at the moment.

Alright, you've made up my mind. 6 puck it is. For those of you wondering, the greddy type-s sounds like a damn baby fart. Makes me miss my TurboXS RFL
#20
Nice work, hope it holds up. Definately get a 6-puck to hold the power, and it should last for awhile. The stock n/a clutch won't even hold the power of a streetported n/a, let alone a turbo'd n/a.

I've got an ACT 6 puck clutch and it's great. Of course I have no boost, but I got the clutch for prep of when I do go turbo or s/c. I can launch at high rpms easily, and this thing grabs like no other. So I'd say go ACT

That's pretty much how i've got it, by baby fart I meant the 'chirp' sound. Where as when it was too tight, i was fluttering the poor turbo

I don't. Silicone hosing breaks down extremely fast when subjected to petroleum products. Couple this with 70+psi of oil pressure, and you just made a very big mess at the very least, and spun rotor, stationary, and turbo bearings at the worst.
