Upgrade to the K27 compressors. Something like 800whp+? Research the K27 kit for the 2JZ. Or go single.
I guess they do use a proprietary K26 flange/gasket. It looked very similar to the T25. I am sure you can go buy the same gasket from a Volvo dealer, or Audi, if you needed one. Might be cheaper, might not be.

Yeah, the gasket is proprietary. I'm glad I brought my manifold in to test it or I would have ended up with two T25 gaskets :lol:
From what research I have done with the K-26, there are 3 variants with each turbo putting out appx. 300 to 350 hp.
How much is BIC's twin GT28 setup? I didn't see it as an option on the products page and I would definately like to save up for that setup. What kind of WHP numbers could it do?
I made 502 whp at 22 psi with a pump/race gas mix, on pump gas on the street it makes about 390 whp at 15 psi, and 470 whp at 18 psi on pump gas. This setup should be good for about 550 whp max.
I want $4000 for the complete kit, or $3000 for the kit without turbos ( which will allow you to bolt on larger turbos like the gt28rs which is good for about 600-700 whp.

This exactly what I want my set-up to look like, but the price is out of my range. I am also looking to push around 400-500 on pump gas, but on race gas I want to put down closer to 700-800rwhp. I know it will be expensive but I want to start with two turbos that can get that kind of power. I was also thinking of using a staggered set-up. One GT28RS and one turbo capable of 500hp not sure yet though. I think it will get me past 700rwhp but not over 800rwhp which is fine with me. I wonder if some can photoshop a slightly bigger turbo in the back, just to have a visual of what it might look?
I still wish i had the cash for it. I'd buy it in a second.
Maybe in the future if you still have it i can buy it from you, My goals are like 450 - 500 RWHP and they sound just right.

So you can't afford that kit, but you want to build a 7-800HP Supra? Have you actually totaled up what it will cost you to do so?

As far as spending $4000 on a kit I don't think so. I am putting the car together piece by piece. Also for toaling up the cost I have learned from my last project not to do that again. I was not happy with all the money I spent thinking I could have spent it on something else. I am building this car for fun, and I am in no rush to finish it. I know for a fact I can put a kit together for a lot les than $4000. I am not trying to talk down on that kit at all, but I can get exactly what I want for a lot less. As a matter of fact that might not even cover the cost of what he paid to get it all together.
If you want a good TWIN kit that can make 700-800HP, expect to pay $4-6K all said and done and how lucky you get.
RacerXJ220 said:
What exactly are you talking about? Just for the turbos, manifolds, oil and water lines, and piping. I am pretty sure it depends on the turbo you use, because those are what costs the most. I like looking at things a little different than most and from what I have come up with it might be right at 4K. Can you tell me why it would cost so much more?
85? said:
Ever see how much 2JZ twin kits go for? Try $8,971.60 for the "650whp" kit from HKS (from HPF.com). I know, you want to piece it all together.
Look around more, and tell me if you find any 800whp capable kits for less than $4,000. You'd be lucky to be struck by lightning twice than have a 1JZ 800whp KIT (which would be so rare I'd soil my pants if I ever saw one even for sale) to include the intercooler, that all the pieces will bolt up, to cost less than $5,000 used.
Buy a manifold yourself. Go ahead. Just FIND a twin manifold that can FLOW enough for 800whp. Not just any twin manifold, one that will actually FLOW enough for 800whp. MAYBE a Blitz or Sard twin manifold would flow that much (800whp is just 150hp away from the designed max), but the 40mm wastegate might need to be upgraded. You're not going to find any manifold that size that didn't come off a drag/race car, and is exotic because only like, three were ever made. Oh, and expect to pay anywhere from $1000-$2000 depending on it's condition (Hint: it will probably have used IHI turbos).
Now buy the turbo's. You're going to need those if you're going to mount them and start fabbing up your own downpipes, intercooler pipes, and air inlet pipes, right? You want 800whp turbo's? Then you're going to need turbos that can flow enough for at LEAST 500hp (not wheel hp), and that's pushing the ONE turbo to the max. Expect to pay $1,000 each or more for DBB units. Don't want DBB? Expect full boost around 6,000 rpms then on a 2.5L 1JZ with units that size flowing through a huge manifold through moderate sized exhaust housings.
Now fab up some pipes. Take the car to a GOOD welder. The intercooler alone that will support 800whp is going to set you back close to $1000, with pipes, and couplers. 3-4 inch piping with reduces, and splits welded in aren't really the cheapest, and neither are the clamps that go with them. Maybe if you went with a dual in/single out style intercooler (custom end tanks? More welding?)
Now pay for welding. The welder will use high grade stock/material with mandrel bends to make the downpipe x2, weld some intercooler piping, weld the dump tube, weld the BOV, weld the O2 bung(s), make the inlet pipe(s) that go to the air filter(s) you have to provide, finish the exhaust with flanges you had to pay for, with gaskets you had to buy, with V-band clamps you had to pay for, all while the car is in a shop for about a week (if they can finish it that fast). Pay for a 50mm wastegate flange to be welded on, or just go V-band wastegate. Yeah, expect to pay $1500+++ for all that custom development and parts fab done RIGHT. That's with you taking parts you already know fit for the most part and just tell them to start welding everything. Just go ahead and throw in all the oil/water lines (dual cooling?). You can't really piece together a downpipe here, or a downpipe there, intake pipe here... they'll have to come off a kit, or be custom made.
That's more than $5,000 right there, and IMO, I'm being conservative. Quality at those levels would be important to me. So would the respected fuel system, and the cams/headwork that would be required to flow that much air for 800whp.
You want to piece it all together, and there's nothing wrong with that. I was being realistic with a time limit of less than say, three years, to obtain everything needed. If you find a K26 twin manifold, it might push out 800hp with some K27's or larger, and you can score one for $4-6K depending on how lucky u get. I'm sure even BIC's kit can hit it with the right turbo setup, and it "could" be possible for under $6,000. I just don't know about piecing something like that together without spending a lot more in the end.
You asked, and that's my opinion. It's cheaper to go single.
Good luck.

Thanks for the info, but I was talking about just the manifolds, turbos, lines, piping 4K sounds a little much. I am doing this one section at a time ie, manifolds, turbos, lines is one section. The next would be all piping, intercooler, BOV, wastegate, downpipe, then exhaust. Next is Fuel management, fuel upgrades, clutch, flywheel. Then what ever small things I miss along the way, but my time line is going to be a lot longer than three years. I just figured I have to start somewhere and I would rather start on the part that would be the most expensive. I am just taking things one at a time, but the main thing is to get an idea and gameplan then take one thing at a time. The first one is just buying the motor, get it going and all bugs worked out, then put a kit together and put everything on all at once. But since everyone wants to run single turbos, I thought about running two smaller turbos would be more fun.
here is my poormans TT upgrade.
GT35/40R split flang T4 DBB will spool low 3k and cost about half of that of any TT setup, easier maintenance having only 1.
I am like a lot of guys here going with the flow going single ...
Also any time you get ct12a with steel wheel upgrade or even mod ct12b to work it adds a lot of lag maybe even more then some GT35R setups.
If i had 5-6K laying around i would go for the TT upgrade of garret twins for the more V8 feel but I plan not do to much track style auto X racing in the heavy MKIII.
