Hello all. Questions and whatnot:

I currently own an 87 SE. I was staring at a chick in a yellow S2K (yummy) a few weeks ago and hit a van. Then the person behind me hit me. The rear of the car is ok, the bumper is a lil cracked, but nothing major. The front however, is toast. Bumper cover, headlight assemblies, hood, right fender, bumper and bumer supports, the list goes on. Becasue of the twisted state of the bumpre supports and whatnot, I decided to not try and repair the car.

So yesterday I went out and bout an 89 GXL. Good looking body, decent interior and such. HOWEVER, 1. its an automatic. and 2. Its puffing notorious white puffy smoke.

So here what I would LIKE to do. You guys tell me if its gonna be ok. Swap my S4 motor over, using the S5 intake and externals and such and at the same time, convert it over to manual transmission.

I dont anticipate problems with the tranny conversion but what about mixing and matching motor parts??? What changes were made from S4 to S5.

thanx.....and sorry for the long and drab post.

 

the intake will be hard to fit its kinda tha same as fititng one to a 12at sorta thing (if ur tlaking na the manifolds would be great to put on (see thread about it)

dont know anthing else

 

It can be done, and there are several write ups on-line for both the tranny and intake swap. However both are not simple bolt in, and some minor modifications will be required.

The only thing that might get you is if you have emissions testing in the area... It is technically illegal to go backwards in engine years, but since the series 4 motor burns cleaner than a series 5, you might be able to get away with it, as long as your emissions testing is not too detailed.

 

Well after reading about all the stuff needed to mount a S5 intake on a S4 motor, I ask this:

Can I just mount the S4 motor in the S5. Will the vaccum, electrical, etc work out.

Im asking casue the S5 has a sick motor, and a really sick slushbox in it. And sitting in the wrecked S4 is a super great motor and good shifting 5-spd that jsut needs a clutch.

tnx.

Yes, but you will have to swap front covers in order to run the s5 Electric OMP.

 

Are the S4 and S5 short blocks the same? Just the outside?

 

What exactly do you mean? I havent taken inch by inch comparision between the two but I was lead to believe that there are some differeces....

 

No, there are some minor differences in the housings, including sparkplug placement.

Mounting and intake/exhaust locations however are the same (or close enough for government work).

 

I am going to put a rebuilt s4 shortblock in an s5 car with all the s5 long block engine conponents. Sounds like it shouldn't be a problem.

Anyone say it will be hard to make them match?

 

Or swap to the S4 ECU and wiring.

This is a complicated swap, but you've got all the parts you need to make it work.

The wiring swap is a grunch of work. I remeber to do it right you also have to swap the main harness

 

and swaping front covers isnt'??????????

LOL

That Is an Interesting point Icemark. On how the series 4 motor burns cleaner than a series 5. How so?

 

I should clairfy that; its the actual car rather than motor. The series 4 cars had lower emissons than the series 5 cars, so a jumbled it all together with the engine got lower emisssons.

So I may have been incorrect in the engine being the only reason for the better emissons output on the series 4 cars. But with the only real emisson device differences between the car being the ECU and Cat(s) it would be hard to draw any other real conclusion for the lower emissons.
