Plenty of room now for the T88 turbo and wastegate. I trimmed the bracket, and threw it back on just to show the amount of room that I have to work with. Still need to do some more trimming to it here and there, as well as rounding off the edges to make it look factory. I will polish it up when the engine is disassembled. If you notice the wrapped wiring in the second pick... I pulled the secondary fan wiring from the starter harness that gets plugged into the passenger side cylinder head, and will be rerouting it to the front of the TPI manifold. The only wires that will be near the turbo header will be the spark plug wires, and those will be MSD. Also need to pick up a steel sleeve for the long bolt that bolts the bracket onto the cylinder head through the smog pump, as otherwise with the smog pump removed putting it back on without the sleeve will crack the bracket.

That's similar to how I did mine I'll take some pics to show you I also went ahead and got rid of the bottom bracket just for looks

Street Lethal

iTrader: (16)

I hesitate removing the bottom bracket for the smog pump, only because I worry about stress cracks. How is yours holding up, have you checked it out for any stress cracks since the install?

No problems at all here I've been running that setup for over 3 years I even ran it with a mechanical water pump I recently removed it when I had the engine out just to paint it and it looks as good as it did 3+ years ago

Island dragway located in Great Meadows, NJ. Its a bit further north west of E town, But comming from long island, its takes less time to hit Island than E town <less traffic and bullshit>. You get lots of runs at Island also. One of my buddies clicked of like 15 or 16 passes on night just for shnitz n giggles. Its not super prepped like e town and its a smaller crowd. But the wed night BBQ n racing is fun.

Honestly i hated e town after like 03/04. 2 passes on test and tune night. Really? Only good you tend to meet more people. But hey what ever floats your boat. Atco is to official for me. And far.

Not really, been so busy with work and then planning for Easter it's been one big headache. When I had to cut the turbo header to clear the K-member I had to cut the crossover too, so now I am just waiting to come across the right ball flange to match the one on the drivers side. I had a universal one from Walker before I cut the crossover to clear the K-member already welded on, but I didn't like like it, so I cut it off and scrapped it. I already welded a flange on the turbo header that I cut off from the stock y-pipe ball flange (female side), now I just need the male side. Flowmaster has one, but I'm not about to pay one hundred dollars just for that flange. Will pick one up from Meineke when I get the chance, as they were the ones who did the drivers side anyways a few years back when I had the y-pipe done...

34blazer

i was going to use these but i needed a female side. you want 'em? i put the H pipe from my mustang on to my blazer last summer but since im going turbo im not going to need them anymore.


*edit* stupid uploader failed to upload even when i zipped the pic. i went on summit and you can see the male ends on the back of this hpipe. thats what i have, pretty much brand new.

Street Lethal

iTrader: (16)

That is exactly what I need, are they 2 1/2"? I only need just one male ball flange though, and I would of course pay you for the flange as well as pay for shipping, but I really wouldn't want to see you cut up a nice setup like that just for a single flange...

34blazer

i already cut them off last summer, i was going to weld them back on when i buttoned upt the rest of the exhaust but i wont need to now since i decided its turbo time lol. theyre both yours

and they are 2.5" as well

Street Lethal

iTrader: (16)

If you are positive that you won't need them, that would be awesome. Send me your paypal address, and I will send you over whatever you need for them, include the shipping...

terrorsquad77

Just out of curiosity, what is your budget on this build?

Street Lethal

iTrader: (16)

Not so much a budget, as I am mostly working with what I have that is readily available. The EBL P4, the TCI converter, and the suspension upgrades (including the drag radials) are the only things that will cost money, and even then those items aren't that expensive. I don't mind spending money, but to throw a hundred dollars on one single ball flange from Flowmaster isn't cost feasible to me...

34blazer

sh*t, if i needed something like that id just buy the whole foxbody offroad h pipe for 130 lol. its easy to modify, i bought 3 of them, one on the ram, the blazer, and of course the mustang. ill have to check my paypal, havent used it in awhile but ill have my wife ship them out to you prolly tomorrow so you (hopefully) have them by this weekend. im positive i dont need them too.

34blazer

hey Rob shoot me your addy and ill ship those male ends to you tomorrow so you have them hopefully by this weekend.

ill update my paypal and just cover the shipping

Street Lethal

iTrader: (16)

You don't have to ship them out that early to me, take your time. PM me your paypal and what you want for them, and as soon as you get the funds you can mail them out, no rush...

Had anytime to play with the car Rob??? Updates???

Street Lethal

iTrader: (16)

Not really, I've been sooo busy with work. Joe (34Blazer) hooked me up with those ball flanges, and I welded the one I needed onto the crossover the day that they arrived. Just need to smooth the welds down and the crossover is finished (the drivers side header is already finished, air fitting welds were all smoothed down). Just need to weld the turbo and wastegate flanges on the turbo header at this point, as the center primaries were already welded into place. Then all that is left is to have the welds smoothed down on the turbo header, then everything is off to get coated...

34blazer

cool man looks good

Looking good rob!! Definetly show some pictures after they get coated if ya can,

Just a small update. Was originally going to use the stock GTA's plenum w/its stock throttle body because the earlier setup that I modified for the other build has a completely different IAC routing, as well as different throttle cable setup. I decided to modify the earlier plenum to work with the later GTA's throttle body, this way I can also use the earlier runners from the other build as well. Just need to drill and tap another vacuum line on the older plenum as the newer one has a third port on the rear where the earlier one has only two in that area. Here is the completed plenum, as well as the runners that will be used with it (runners; before and after)...

Street Lethal

iTrader: (16)

Just so you can have the proper visual, the lower ports of the runners were ported the same way as the upper ports to help with velocity, they lead from the siamesed plenum down into the siamesed lower intake ports on the manifold. The runners were painted black. The only thing that wasn't ported was the throttle body, and I'm not going to because it flows more than enough. Just going to polish it up...

fasteddi

iTrader: (2)

Rob, Those injectors look really familiar....

Im trying to learn a bit from your build. I got a buddy into drag racing the otherday. Hes making 15.7 sec passes on his 305tpi firebird. And wants more power..lol. I said its turbo time. I think he was asking you about cam selection... thanks for any help you can give him.

Street Lethal

iTrader: (16)

It really depends on his collective setup. Unlike super chargers, turbo chargers are not really effected by too much overlap, and that is because the gases that escape the quench are still at least usable to be able to spin the turbine. Although at the same time too much overlap also increases reversion along with it, which will slow the intake charge down, something you don't want with a stock Tuned Port Injection system. Once he sets a goal for himself, it should be very easy to determine which cam to go with, especially after we know which cylinder heads he will be using. Yeah, I like the look of that blue metallic paint. I even painted the manifold that I converted from TBI to carb the same color...

PhoenixFirebird

iTrader: (2)

Hey that's me

Mark is convincing me to find an LT1 cam instead. Keeping the stock heads, just going to port them this winter probably, along with siamesing the runners, plenum, and manifold like you did. LT1 cam with 1.6 rockers and new springs sound good? Right now no other plans are being made, other than a new rear gear, until at least later on in the year.

Anyway, this thread is very interesting. I want to see if it can be done! Might give me motivation to build a turbo lol. I really like the look of that blue metallic paint. Keep up the nice work! Can't wait to see how this turns out.

fasteddi

iTrader: (2)

Dont wana run over your thread rob but.... Andrew "if" you add a cam. We should port everything at the same time. Just a though.

Keep a eye on this thread andrew as you may go this route someday??

Street Lethal

Minor update, I pulled the stock plenum off and installed the older modified plenum to see if it would cause any problems with the newer throttle body in reference to the IAC routing. No problem at all during idle. When pulling the old plenum I noticed that it was filled with fuel, so that immediately told me the diaphragm in the regulator was shot, but it is now fixed. Need to set aside a day and get the heads, cam and modded TPI system on there in one shot, then take it to the dyno to see what it will do first without the turbo...

Street Lethal

iTrader: (16)

I don't mind at all. By the way, get that little V6 of yours dialed in all of the critical areas, including your launch, as I don't want any excuses for when we take a ride down there and run you naturally aspirated w/out the turbo...

Street Lethal

iTrader: (16)

It's turbo time. There might be a change in which turbo I will be running, as I came across a very sweet Turbonetics true 66 Ball Bearing turbo for a very good price. This particular turbo has propelled my buddy's T-Type to a 10.10 second pass at close to 140-mph, with a horrid sixty foot, and should be more than capable of getting me my nine second pass. I am building this car to be a street car, so there is really no need to go overkill with the turbo that I was planning on running. Just a quick pick of the turbo(s) to show you the size difference, as the 66 on the left will easily clear my hood. Also considering a FAST-SFI setup now, just need to find out if a buddy of mine can convert it for HEI-V8...

iTrader: (20)

Try the smaller turbo...if it dont work, go bigger

Street Lethal

iTrader: (16)

Been going over torque converter options w/that ball bearing turbo, as I might have to ditch my TCI and spend a decent amount of money on a Precision converter. Have you swapped converters with the changes you made, or are you sticking with the one you already have...?

Orr89RocZ

iTrader: (20)

Stickin with the one I already have. It MAY stall abit higher with more power but it didnt seem to change from 8 psi to 17psi so I think its gonna stick around 4200 stall which is right where I want it...even tho this combo should rev up alot higher, I dont want too much more converter for the street. I got a 12 bolt rear coming and it will get 3.08's likely so I'll be very comfortable street driving

project89

iTrader: (1)

pfft run them both and do a compund setup

Drac0nic

Hope it's a 4 bolt turbine, I'd think a 3 bolt would be a bit tightish unless it's the big A/R Precision housing. with it being a BB 66 it should have insanely quick spooling I'd think and make for a wicked street car. Maybe even eek some 9s outa it, but the catch is gonna be where it runs out of steam with the higher CID. If your heads flow 200 CFM, and you've got 8 cylinders that's gonna be roughly the equivalent of:

200*8/6=266.667 CFM

in regards to the Buick heads. That's a pretty big head for a turbo buick. Hell, a set of stock Vortecs would be:

301.333333333 CFM

That's Stage II head territory. Just saying that you may start "pushing down" the map with the flow you have. Will be interesting to find out.

Pulled the car halfway into the garage this morning and was preparing to pull the stock TPI, heads and camshaft, and then installing the new and modified components by this afternoon. Engine "sounded" like it was suddenly knocking, even with decent oil pressure. I might have to pull the engine and throw new rod and main bearings on it just for my own peace of mind, even though the knocking sounds more like a cracked flexplate to me. Took a quick video for your viewing pleasure. The surging at idle is due to the removed smog pump, as the $8D mask is programmed to subtract 100mV from the R/L threshold, and the engine will run much leaner without the air pump, and will continually try to correct. That is a fact, because not only does the surging go away with the smog pump reinstalled, but you can see it when you datalog. It can be programmed out, but I am switching engine control anyway...

Street Lethal

iTrader: (16)

Update: Flexplate is fine, and no more knocks, the engine was actually detonating if you can believe that because of the smog pump removal. It was running that lean when the air/fuel would swing. Learn from this $8D users, you must disable the smog pump when you remove it. Reinstalled the smog pump (finding the right size belt took freaking forever), and the knocking at idle went away, entirely...

Street Lethal

iTrader: (16)

The heads that were on the T-Type at that time of those runs were 1.90/1.60 Champion GN1 heads, flowing 236-cfm @ .500". There is currently a 3-bolt exhaust housing on it now, but I have the option to switch to a 4-bolt exhaust housing which I would definitely do, the a/r is too small w/the current one. Also considering a Holset VGT that I would trade the larger turbo for w/additional cash, but I'm really liking that Turbonetics 66 ball bearing. Your right about the spool time, it would definitely be insane...

Street Lethal

iTrader: (16)

Update: The modification below was worth about 800-RPM on the stock engine at wide open throttle, possibly a little more if I didn't ease off of it, the plenum is all I installed so far, and it made a world of difference with the off idle transition. No tuning was done whatsoever, the IAC was not adjusted in any way, shape or form. Just got back from pushing it on the highway, and am more than satisfied w/the results...

Transmission mount ripped apart after a couple of days of boosting the engine, then the outer tie rod went as I was pulling out of the driveway a few weeks back. THANK GAWD the tie rod happened right in front of my house and not on the highway. I had pictures of the progress, and I think I left off in this thread with the turbo and wastegate flanges needing to be welded on. I went with a 1/2" T4 turbo flange from OBX, and 50-mm wastegate. I'm going to wait to have some dyno and track video before I startup the final thread..

Heads are off, and I started a thread over in the TBI section as I am redoing a set of 187 heads for this engine build, and the T66 is off in favor for a T72 that I picked up in a trade that I made. One last thing after that, I am switching to E85 because a station just opened a few miles away. No track videos, though the T66 would have gotten me there, there is no doubt in my mind...
