Okay. Right, I can see the use with swapping to the smaller engine in JGTC. But my comment was about the Top Secret Supra, why swap that when horsepower is going to matter more than weight?

 

Why break bricks with your head?
Japanese are masters of doing things 'just cause'.

 

Lol... yeah.

 

I think that some of you are mixing two of the most known Top Secret supras. The one that`s most known for it`s top speed-abilities is the one with the RB26-engine, made famous by Mr. Nagata`s top speed-attempt on the UK A1 highway. This car, iirc, was built together with a R33 or R34 GTR, to break the 0-300km/t record for both rwd and awd cars.

The other car is the Top Secret GT300, a "jgtc-replica" with the 3S-GTE in it. This car is actually here in Norway now, bought from Top Secret by a jdm car-importer. This is a pure track-car.

Ninja-edit:
The GT300 is for sale again. Buy it!

+2 for providing link with slutty Norway girls in it

BTW, what's a 'ninja-edit'?
I missed the memo on that one.

 

2 points for thought, but at least it ain't a v8. Different kind of idea though not bad, but i wouldn't do it.

 

If I mixed it up, then the Super Street magazine that I read like 6 years ago that did a story on it mixed it up.

Which I'm not doubting the possibility of...

 

RARSON I know the rb26 powered Supra part is correct. I think the 3sgte one is also true, on Super street they had a issue with the top 10 engines of all time and the 3s powered supra was on their and it has become a straight track car. I think the motor made it become like a MR car with a 50/50 ratio cuz how far back it sits.

P.S. cool idea but like I said as long as it ain't a v8 I'm fine. But he didn't thrash the rotary he just wants to do something different so I can't argue with that.

 

Dude, all I was saying was that I read in SS that the 3S-GTE-powered Supra was being used for top speed. They may have been wrong. But I know I read it, a long time ago.

 

no you are right I was just glancing through my magazines and came across it I think it's like 4-5 months old and it made like 700hp. Personally I think most swaps are reasonable as long as its for the right reasons in most cases.

 

I was thinking about the 3s-gte before I didn't the Sr20det... I couldn't find any consitant info' about mounting it RWD. I've seen it done but with no write ups or real clues... I do believe Toysport can help... but I didn't want to rely on them.

The Sr's intake/exhause are on the same side as the 'get's and was worried about the heat and fuel line issue too. However even with out heat sheilds I had no running issues... it only crosses in the small section where the firewall becomes the bottom of the car. The fuel flow in itself keeps the lines cool, remember it's a return design system so the fuel is always moving.

I would recomend just going with the Sr'... it's unbelivably easy to swap in.

 

^^ thanks. i read your write up on the SR swap. it does seem rather easy. all you really need is the engine and front subframe. theres a good importing place near me that i know i could getthe stuff relatively cheap as well. do to some info i received just before christmas there wont be any swap going down for some time. i have to under go a $30k surgery some time in the near future, whenever i give the go ahead. after that ill be leaving for college in the fall. after i get all settled in at college ill start seeing what i can do. so ill probably see this swap within the next 2 years if all goes as i plan. if not, after college most definately.

 

Randomly came across this thread. It's a common misconception that the JTC cars ran 3S-GTE motors. Although the teams claim this on their websites, they are actually 503E motors from which the 3S-GTE bottom end is derived. (Toyota mandates the 3S-GTE name to be used for marketing purposes.)

The 503E began life as an IMSA motor and was most famously the powerplant for the Rod Millen Pikes Peak Celica and Tacoma. In qualifying trim these motors are good for over 1000 HP.

The 503E layout is very similar to the 3S-GTE but with a much more aggressive head treatment and forged internals. Another key difference is that the 503E is a Toyota works motor while the 3S-GTE is manufactured by Yamaha. (The head design of the 3S-GTE is Yamaha's as well.)

Here's a decent but brief overview of Toyota engine history with emphasis on 4-cylinder motors:

the 3s is a great motor for any amount of power. But my main question is: what transmission needs to be used.

the stock 3s trans is all wheel drive for the GT4 celica. I guess a custom housing could be made.

 

my guess would be a beams tranny from the jdm altezza or is200

 

well the 3sge Beams is FWD. I am a celica owner so the 3s swap has been completely looked up on my part. I am unsure if there is a RWD beams but I am sure there is something.

But it seems like you are implying the beams is used on the altezza. Ill take your word for it, cause I am not sure.

 

I dont think this is a good engine choice for a swap. Heres why:
inline 4-cyl engines by nature are tall, and tall engines dont fit rx-7's very well. You can make them fit but your going to have to mount the engine on top of the crossmember because its going to be to long to fit behind it, or your going to have to cut up the fire wall like I'm doing with my swap. mounting the engine on top of the x-member is bad since its so high up and places the weight to far forward... this isnt good for handeling.
