R154? Good or no good?

This doesnt really make much sense TBH

A rail is a type of hot-rod

[TTV8RA23]

A rail car is what i was reffering to full tube frame chassis long and skinny ultra light weight Drag specific only. Its gonna be my second project after the celica is finished as i would really like to get into drag racing seriously but dont wanna chop up the RA23 and put a cage in it so talking about it with my old man i decided two projects is gonna give me the best of both worlds and is the right way to go.

I think he was referring to the drivetrain/engine combo.

For a rail put in a 9 inch, 6 speed auto would be a waste of time and money, methanol on a 1UZ shouldn't be wasted on a couple of T25's.

[TTV8RA23]

I already have a the six speed auto as it came with a 3UZ that my old man bought for a jet boat and i dont belive the fact that it is a six speed is a waste of time as the turbo and motor will always be right in the meat of its response/efficiency range and if you have it with no other use for it why not use it i say? An auto is always putting drive down even when it is changing gear (i believe???) so even if it has to change gears more times than the standard 3 speed they might choose otherwise why not use it cos its still always put drive to the ground and as previously mentioned the motor will always be in the perfect rev range. And im not gonna run a nine inch because i believe a standard 9 inch is no stronger than a hilux diff and a nine inch is too heavy for my application anyway. I want to use a hilux diff as i can get them extremely cheap and have shortened a number of them before so i no what is involved. And could you elaborate on wasting the motor on a couple of T25s? I dont really understand what you mean. The idea for the car is not huge horsepower the plan is to keep it as light as possible and make 700-800hp at the crank (which two T25s are perfectly capable of and spool up quickly) and hopefully run some 9 second quarters im just been realistic at the moment and what the future holds for is may be something completely different but at this stage that is the plan for the biuild as it will be relatively inexpensive and easy for me to build myself. I want a reliable fun car that will run reasonable times and that i wont have to spend thousands of dollars on every outing just to keep it maintained and running properly.

A T25 has exactly no chance of making 400hp sorry.

The 3UZ will also self destruct long before 800hp flywheel, they have weanie conrods.

A bit of a rethink required.

[TTV8RA23]

If you read the article it says im using a 1UZFE with a 3UZFE gearbox. And i must have been seriously mis informed or quoting the numbers seriously wrong as far as the T25s go then. .63 exhaust housing with a .7 A/R compressor housing. My old man has one on a subaru motor he is putting in a jet boat and been quoted by the garret guys who sold him the turbo 450hp+ so in my mind if you multiply that by two it equals 900hp??? like i said im probably quoting the turbo model wrongly. My mistake.

[5000gt]

depends on the model of t25......

regarding your clutch/flywheels, i'm very interested to see your machining skills as i am in need of a good twin/triple setup for my setup..... think of it as a tko600 matched to a 1uz (1gz in fact, but same as 1uz in terms of flexplate and pcd).

What kind of pricing would we be looking at???

No probs, my bad on the engine. A stock pre 94 will make 800hp on stock internals but how long it'll last is in the lap of the gods

A T25 that will make 450hp is no longer a T25 Could be a big GT25? GT2540 will go close to 400hp on a 3S

[TTV8RA23]

Yeah GT2540 or GT2535??? sounds right its going on a pretty serious EJ20T. Paid 2k for it its full ball bearing oil and water cooled etc etc. Genuine garret and im looking at buying two of them for the 1UZFE it will be running methanol with electronic injection and water to air intercooler. Just hoping to have a fun car to run some quick times that wont cost me too much to build.

[WDE_BDY]

My personal opinion is if you want a rail, buying one setup already less engine and trans will be the most cost effective. The reason I say the 6 speed auto is a waste is because it won't handle the power and will need considerable $$$$ to make it do so plus dealing with all the elctronics etc. For a lot less money you could get a prepped powerglide which will be faster and has the support and converter knowledge readily available. For the diff in a rail you will generally find full floating hubs, fully braced custom housing with aftermarket centre. There isn't the same support for the Hilux so its common sense to go 9 inch. And as mentioned T25's are alot different to GT2540's at $2k each. But I'm sure you'll be researching this alot more yourself before you start spending money.

If you read it i mis quoted on the T25 i meant a GT25. And no the frame/chassis would be alot easier and cheaper to build myself than try and buy cos as i stated i can build the hole thing myself and can get a fair bit of design assistance from a mate of mine who has built numerous rails before some running into the 7 second zone so im sure ill be alright as far as that goes. As stated also im building it light so there should not be a huge strain on the diff. I will use a locked center so there is no worrys about the usual weakness of hilux diffs been the spider gears. And the axles are bigger than 9 inch axles as well so with what im doing with it i think it will be fine. As quoted im going to try build it cheap so dont want to be spending mega bucks on after market diff housings and billet axles etc etc. I also have contacts for getting the auto rebuilt to handle the power quite cheaply so again its cheaper for me to do that than spend shit loads of coin on an aftermarket powerglide. Its just gonna be a weekend toy for me and my old man its not a full blown serious drag car so yeah

[CrUZida]

As Callum said, the 6spd auto will melt long before you reach 800hp. And to the best of my knowledge no one knows how to beef these up.

The stock 4spd auto can be beefed up to handle that, but will die before 400hp if left stock.

[TTV8RA23]

Well we have about ten 4 speeds lying around the workshop that come with all motors we have been putting in boats and a van and a hilux so thats definitly another possibility. I also know a mate who can beef these up for me for FAARK all so yeah either or.
