I am looking at racing a Toyota Supra in the NHRA/IDRC/Summit Sport Compact All Motor class in the near future. Trouble is I currently race an old school air cooled VW bug; 10:40's @ 127 mph and do not know much about the Toyota Motor. The racing sanctions are putting more restrictions on the air cooled vw's so we can not be competitive any longer, which is the reason I am switching. Does anyone know alot about the 4 cyl Toyo motor and can recommend an engine builder? I need to squeeze at least 300 plus HP out of a motor to compete with the Hondas and RX7's. I will be building a 82 Toyota Supra, I can not stand front wheel drives, and building the complete cage in the car. The car will be stripped, lightened, have a rear end swap etc.. If anyone knows someone that races this class it would be a positive also. Thank You in advance for any and all information, Matt
Yep, the rules will not allow a 6. You can only run a 4cyl or a 2 rotor motor, naturally aspirated only. I am being given the 82 Supra so it will help keep the cost down. All the money will be in the motor/trans and fuel injection/management system.
and put something like an old school kit car body on it for aerodynamics. (How does that thing not flip @ 127mph LoL! I've ridden in old school beetles, they're like waiting to hop off the ground @ 90mph on the highway and it's awsome!)
Hey I'm curious to know which VW engine you're using. I know a great tuner can get 200hp out of those things. Atleast for a short amount of time.
*edit*
The RX-7 and Subaru swaps are pretty common if I remember correctly. How freaking cool would it be to be racing a kit car VW Beetle with a built rotary in the back hahahahahahaha!

Originally posted by UfoZ8myCow Try doing a little research on the 3SGE and 4AG motors... The better bet would be the 3S though.
4AG Atlantic motors make 240HP N/A, thats asking a lot from a 1.6L. Haven't heard much about built 3SGEs, the Blacktop 3SGE in the Altezza RS200 makes 210HP, haven't seen any modded though.
How about 18-RG's (IMSA GTU cars made 300HP) or 2/3T hybrids (like the Ricans, they're mostly turbo'd though) or even 3RZ-FE's if you're feeling like doing some development.
Btw, the Supra chassis might not be the best one for you, its heavy compared to lighter cars like any of the RWD 'Rollas, hell the KP61 Starlet weighs nothing if you can find one.
The 85 Celica would be your best bet. Small 2 door with a RWD setup. I believe the GT-S would be your best bet. The engine in it was the 3s-ge from what I remember (I may be wrong), which would be a fine engine to build on.

The 4AG and 3SG in n/a trim are NOT a drag motors so don't even bother. They are proven track engines that make power wayyyy up there.
Best bet would be old school stuff... Built up 20/22R hybrids do well along with 3TCs, 18RGs, amougst a few others. If you wanna look into new motors... 2RZFE's make big torque and have a fairly broad powerband... but aren't very proven in n/a trim.
If you're going turbo... Toyota makes some of the toughest boost eating motors in the world. There's a guy with an AE86 running a turbo 2RZFE running high 8's in the 1/4 mile. Other common turbo'ed Toyota drag engines are 3SGTE's, 3TGTE's, amougst others.

Originally posted by SmokingTiresV6 Sorry, I mis-typed it earlier. I was speaking of the 85 Celica. Because the 85 was the last year that they were RWD
Wouldn't that have still been the 3s-ge? Or was 86 the first year for that engine?
Kwanza: No 4cyl is a drag motor
And he is going N/A. He has said that twice now. No turbo, no Supercharge, nothing. All engine.
I know what he said that... that's why I separated the with paragraphs. FYI... 4 cylinders have proven themselves over and over on the drag strip... so you can just keep telling yourself that 4 cylinders aren't drag motors. Hondas have done some pretty unbelieveable drag times n/a (and set some records in the process) and old-school Toyota 3TCs are the standard when it comes to building an n/a Toyota drag car. When it comes to the Toyota motors... they are PROVEN engines on the drag strip and have been around since before most people here were even born... so don't try to throw down these engines unless you really know your stuff. Then again... you can't even figure what gen Celica the 3SGE came in (86-89 FF Celica GTS... the last of the RWD models ran from 82-85 all had 22Rs). FYI... the 3SGE is a track engine. It has its limits when it comes to building a drag motor. Power is not as essential as broad torque... so you can't build a good pure dragster with an engine, that when is fully built, doesn't even start making power till 3000-4000 rpms... get what i mean? A nicely built 2/3T can be bored and stroked from 1.6/1.8 liters to well over 2 liters and that engine can lay down the torque and the power.
My suggestion still stands. I'd reccomend using either the old RWD TE Corolla chassis or the KP Starlet chassis. Both of these are extremely light (~2000 pounds) and are Front engine Rear wheel drive. You can put just about any Toyota 4 cylinder under the hood. 20/22R, 18RG, 3TC, 4AG, 3SG... just to name a few. Toyota has a habit of recyling bellhousings also. As far as the rear-ends go... slap on a truck/CelicaSupra (almost identical) rear-end and you'll have nearly unlimited choices as far as diff options go. Final drives, LSDs, whatever. It's all available.
