would there be any problem in putting a 1986 automatic GTU in to a 1988 5 speed GTU? and if so what are they?

 

Yes. It's lots of work.

You need to change the flywheel to a pressure plate.

The mounts do not match up and youll have to custom make a bracket.

The Autos quite frankly, are complete slushboxes, it will cost you more than the car is worth to put the auto into it.

 

even if i just use the motor and not the tranny? im buying the car for only $250 and the engine is in great shape. good compression and everything

 

If you're talking about swaping engines just change out the flexplate/cw/tq converter to a flywheel/clutch assembly and drop in. Other minor issues will probably arrise but they won't be so bad that you have to tear apart the car to fix it.

 

so it will bolt up to my 5 speed just fine

 

Given you have that stuff yeah. Also I think that auto e-shafts don't have a pilot bearing(could be wrong) so probably double check that.

 

Oh if youre referring to the engine, yes it will work fine.

You will need to remove teh flex plate then install the flywheel and a pilot bearing.

 

just wondering how much more horsepower would a catback racing exaust give my car. cause my 88 has one on it and it is fast.

 

so i should have no problems than? i dont have that much money either.

 

Cat-back isn't exactly comperable to "racing" but i'd say from 5-12bhp

 

it said racing on the box

 

Dear lord. Where did you pick up your cat-back?

 

Every aftermarket part for compact sports cars either says "Racing", "JDM", or "JDMRACINGDRIFTSUPERDUPERLOVEYOULONGTIME!" on it these days. It's purely marketing. Like "low fat" or "Reduced sugar" dosn't mean it's better for you.

 

My point.

 

ok thats weird. and it was a 86 gxl

 

Naw its just marketing.

Typically a race car will have the bare minimum of things and is generally purely concerned with performance and race regulations. That generally means no emmissions equipment at all and very light mufflers(which do little if anything). A "cat-back" is a system designed for the street driven car who's owner wants a different sound/tone for. Its minimal power increase compared to replacing the rest of the exhaust with performance components. It also has more to do with looks and sound than anything.
