Default Turbo Project...

Well I've been thinking on a turbo project or buying a turbo car... I've always liked the sound of a BOV and it just makes the car.... My question is I know a Supra is way to expensive especially the TT ones etc.. But could i get away with spending 7 to 10 k on a turbo car... I'd really like a SC to keep the lexus name and some of your guys SC's are incrediable looking..

Also can you turbo a stock SC or do you have to do the swap? I'm little confused on what the terms NA-T means....naturally aspired turbo? and all the different engines... etc... I'm still somewhat of a newbe so bare with me ok...

I think having a turbo car would be neat and enjoyful... and down right just plain awesome...

Yea i know....I haven't been around long enough to know about the SC... I've only had my GS since April and I'm not to familiar with the different engines and the proper way to turbo a SC... Everyone does the engine swap so I was wondering if there was a easier way?

To sum it up as easily as possible.....

Motors:
1) 2JZ-GE: Naturally Aspirated motor. Stock in SC. 3.0 liter NA
2) 2JZ-GTE: Twin turbo motor out of MKIV Toyota Supra. 3.0 liter twin turbo
3) 1JZ-GTE: Twin turbo motor out of JDM Soarer, Chaser and some other Japanese cars that I can't thik of right now. 2.5 liter twin turbo.

Transmissions:
1) W58: Factory 5spd trans offered in the US market SC300. Fairly weak. Rumored to handle 350HP or break at it? Who knows.
2) R154: 5spd out of JDM Soarer. Very choice. A lot stronger than the W58.
3) V160: Trans out of the TT supra. Very stout and beefy. Will pretty much hold any thing you can throw at it.

Now there are differnent routes that you can go in turbocharging an SC. There have been a dozen arguements on which is the easier path to travel.

The first option would be to turbo the stock NA motor. This is where the term NA-T comes from. The list of companys that have kits out for the SC is extensive from what what it was a few years ago.

That's just to name a few that I can think of right now. Then you have the route of swapping you're motor all together. The GTE motors are pretty much direct bolt in's. There is actually a book published by CL's own Phil Auldridge(spl?) that covers the swap of the 2JZ-GTE motor into the SC. Everyone knows that the the 2J is the stronger of the 2 GTE motors, but the 1JZ is strong in it's own right.

Then you have you're transmission choices. The W58 which is the stock 5spd was known to be problematic. As it it breaks easily. Some people say that it will hold 400, while others say that it breaks around 350. Who knows right? It all really depends on how the trans was treated before. The R154 is better than the W58. Stronger and better. Why you ask. It came with a turbo'd motor. It's just built better. Then you have the V160 getrag 6spd out of the Supra. Very strong in every way. Capable of handling 700+ horsepower, this is one of the greatest transmissions built. in my opinion. But they sometimes come at a hefty price tag. They also take a little bit of finesse to get into our trans tunnels. Or you always have the choice of going with a number of automatics (slushbox if it's not a TH unit)

Any number of these combinations will work. it really all depends on what your budget is. Just remember not to half *** anything. Do it right the first time. But hell what do i know. If I forgot anything anyone can chime in.

WRONG!!!! why is my third gear shot? hahahaha j/k. I'm just pissed that I have to skip third every time I drive. And the hunt for another used getrag scares me. I just don't want to end up with another broken 6 spd.

As for the tunnel mods. I'm not sure if it matters through the years, but my car is a 92 and used to be an auto. I never banged the tunnel in any way. It went right in. I did have to cut the auto shifter hole bigger to accept the 6 speeds a arm.

Can't afford the downtime right now and i've heard good and BAD stories on rebuilds. Plus, th eonly place i have found that can rebuild them properly, is in Texas.

Sinister, you forgot about the 400.
1UZ-FE 4.0L V8
You can also turbo the 400. Turbo the GS400
My SC400 TT made 371 RWHP & 355 TRQE on 7-8 PSI,
And 510 RWHP & 489 TRQE on 17 PSI

The manifold is stock, but 8 additional injectors have been installed on a piggy back system. They come on with boost to ad the extra fuel.

The Turbos are toyota ct-26's the first set was off of an mr2 smaller ct-26's with a split exhaust housing. I made 371 RWHP at 7 PSI with these.
Currently I have ct-26's off a a supra. these are slightly larger, and I made 510RWHP at 17PSI
