ok did u guys strengh your chassis?? i was told by a guy i know that if when i put my engine in the chassis rails to the fire wall will bend and break ! if u did what did u guys to do to do this??

 

Don't bother, as far as I know the car can take the 13B very well. I never heard of breaking or bending chassis. There are plenty 13B into ex-12A cars around, so if they'd break we'd hear about it.

 

the GSL-SE comes with a 13B-RE and although it contains more structural bracing throughout the car the firewall / C-channel areas seems identical. The weight difference between engines is about that of full tank vs. empty tank; chassis are engineered to withstand loads far higher than their sitting weight, as these loadsd dramatically increase with cornering forces, passengers, etc.

 

The 13B-RE Designation if for the Cosmo Turbo engines. The 13B-REW is for the 3rd Gens.

I believe the SE engines are referred to 13B 6PI (Six Port Induction) from Mazda.

The RE-EGI on your engine's intake stands for:

Rotary Engine
Electronic Gasoline Injection.

The First Gens are Unibodies, and are exceptionally strong all around. Many guys on this forum have over 500 RWHP on them with no problem. (AJC13B, Cach22, Rice Racing), etc.

I do have a Racing Beat Engine Torque Brace that will go on the new engine as well, just to help - and when finished, I will put a 6 point cage in the car.

 

EDIT: Hey, you beat me to it....



The GSL-SE comes with a 13B 6 Port.. Which is far from a 13B-RE..


But, lots of people put down over 400RWHP in the 1st gen, and i have not heard of people bending the frames.. I have a 13BT with a TO4E, but it has not run yet.. But i don't believe i will have any problems..

not to nit pick, but the factory calls any rotary with twin turbos an rew. i have a copied page from the cosmo shop manual (somewhere) and its 20b-rew, and 13b-rew

Yeah, You're nitpicking. To further make this complicated, the Cosmo engine is not really an REW. The REW designation is for the Twin (as in identical, not as in two) Turbos. The Cosmo has s sequential Turbos, but one is slighlty larger than the other, so they aren't "Twins" by that definition.

 

thanks guys i will tell him to pull his head out of his *** and talking ****!

 

By the way j9fd3s, I just re-read my post and I think I came across the wrong way. I posted in fun, and wasn't trying to be an @$$. If it came out wrong, I am sorry.

 

My doors still line up fine

 

no, no dont worry about it, i was nitpicking in fun too

mike

 

I didnt do **** ot mine, and my doors still close, No frame damage here... I think the big problem with a 1st gen is the strut tower flex..
