Question about sp61gt turbo with mods

[917mgte]

Planning to order a sp61gt in the recent future and trying to throw a parts list together and this is what i have so far. Obviously the sp61gt with the oil line kit coated and maybe ball bearing depending if i have enough cash, apexi afc, walbro fuel pump, apexi avc-r type r, 550's (either clinic fic's or rc's if i have the cash), spearco intercooler (already have the hard pipe kit), maft pro, bic ddp (already have this but from what i understand you cant use the stock ct26 ddp with the sp so i figure i will sell mine and buy the one for the sp61), and an hks ssqv with all the fittings. I have a 4 puck fidanza clutch along with the lightweight flywheel and pressure plate, full hks 3 inch super drager exhaust, bic ddp and headgasket.

Do you think i would be good to run this on these mods and on stock internals feed back please???

I'm running the SP61GT with the MAFT-Pro for a few years now and I have the stock internals (plus the HKS headgasket) and it runs fine. There are still some tweaks I'm trying to learn with the MAFT Pro to really dial it in, but it does great as a DD. Just don't push the boost too much and you should be fine. As it sits, my car is really close to 400rwhp/400rwtq. It's a pretty good turbo, but if I had to do it again, I might look at a Driftmotion kit. If you stick with the SP, you might also consider a re-rerouted DDP...it's a little quieter I would think.

Hmmm idk im looking at the driftmotion kit now too!! Do you have any kind of management kit or are you just using the maft pro? What kind of boost levels are you running? And do you have any idea of the cfm on the dm kit?

 

[CPT Furious]

I leave it at 15 psi right now since I don't put race gas in it (and I haven't installed a meth kit yet). I don't know about the CFM of the Driftmotion kits, but they are really helpful with any questions you might have. I'd either shoot them a PM or give them a call. They only issue I had is that the turbo's are currently set up to exit the compressed air forward versus down like the stock setup. Probably not a big issue, but I'm looking for true "bolt-on" affairs that require minimal hassle since I have less and less time to work on the car.

When I asked about it, though, he (BigAaron on here) mentioned that they could send some stuff to make it easier to work with (couplers and pipe). They have a wide selection of turbos and are really helpful.

For management, I'm just using the Pro with 550cc injectors. It's really all you need for a piggyback. It also has the optional boost solenoid which I am still playing with. Future plans include setting up the timing monitor and timing control. If you haven't yet, take a look at fullthrottletech's website and peek in the Supra section. Guys like Cajunkenny are making some awesome advancements with that thing!

Okay well i think ill go with the drift motion did you change the fuel pump or is it stock?

and is the kit bolt on?

Shit ok so i lied my tuition was a little more than i thought......looks like driftmotion kit, maft pro, maybe a new boost gauge, walboro, and 550's.

 

[grimreaper]

the sp61 has been a solid turbo for DD use for me as well. Maft-pro has worked great too. If i were to redo my turbo setup, I'd look heavily into a tubular mani with a true t4 turbo.

You don't need an AFC with the MAFT-Pro.

Stock internals will be fine. Old worn stock parts don't really qaulify as stock internals.

duh lol oops sorry got carried away with typing. So i think for know i am going to go with the drift motion kit, 550's, and a maft pro. Got raped on my student loans :-(

Oh and my engine just got rebuilt about 15k ago

If you're tight on the funds, the SP kit would be cheaper than the DM full turbo kit. Maybe not after you get a SP61GT downpipe and all, but the SP will require less headaches, I believe. In the end, it'll probably be 6 in one, half dozen in the other. You can't argue with DM's service, though, from what I hear so I think they're a safe bet. And I did change my fuel pump. Def look into getting one. An AFPR would probably be a good idea, too. DM just so happens to sell the whole kit for that, too!

 

[GrimJack]

I'll toss some advice into the pool here.

I've done both - the 'bolt on' kit, mine was from Turbonetics, but same idea, and the full kit with external wastegate, PT67 dbb, etc.

If I were to do it again, there's no way I'd go the bolt on route, for a couple reasons. The bolt on kit... well, it doesn't. You need a different downpipe, oil fittings, intake adapter, and you'll have to fabricate a new mount for the dipstick. Basically the only things that bolt on are the 8 bolts for the turbo to manifold and downpipe to turbo. Weak sauce, IMO. Add to this that the full on kit performs so much better and gives you a LOT more options to choose from, and the fact that the cost difference is minimal, and you'll really start to question the bolt on idea.

What really bugged me in the end was the the reason I went with a bolt on initially. This was because my car was off the road and I wanted something fast to get me driving again, and the bolt on unit took MONTHS to arrive.

Both have issues bolt-on vs. tubular. If you get a full kit (tubular), it's $$, if you get a bolt on (WITH A FULL KIT) it's $$ too. I recommend, _IF_ you get a bolt on, get a high end version with all the goods needed to make it work LIPP, or JT series. All the issues Grimjack pointed out can be solved with a full "bolt on" kit, vs a bolt on turbo. if you have any questions, shoot me a PM and I'll talk to you and answer any questions you have regarding turbos, and help you find one that's a fit for you and what you want to be able to do with your car.

I try to make my customers well informed, and do my best to make sure they get what they need, the first time, at a good price.

For the SP61GT, if he gets the right downpipe (BIC DDP) it will bolt-on just fine. It'll mate right to the stock mani and cat/test pipe. The only thing that I can think of that didn't bolt back up was the stock accordian hose. If yours is fairly new, you probably have enough flex to fit it. I "think" the outlet pipe on the compressor side will go where it needs to. Good luck with whatever you get! Lots of people here willing to help! I really had the turbo itself on in under 30 minutes from starting the job.

Jeff here really does know what he's talking about, and I can't recommend him highly enough. When I bought my bolt on Turbonetics unit, I unfortunately did not know about him yet. It didn't come with a wastegate actuator, and the stock one, well, it certainly didn't bolt on. The place I bought the turbo from had no clue. After digging around a bit (ok, a lot, dammit!) I found some vague hints that pointed me to Jeff. I called him, and it was like a breath of fresh air while rotating the compost heap - he knew EXACTLY what I needed, and he found all the bits for me in under an hour, as I recall. I think he shipped it via teleporter, too, because it was way too fast to be mere air freight.

 

[jtamulis]

AHAHAHAAHA. Thanks GrimJack. Seriously, tho, when you're ready to buy a turbo, contact me. I'll help you get the best setup for what you're wanting to do. Helping people get their projects right, the first time, is what I do. And I can usually pricematch anywhere.
