What parts did acura change on the tl to give the tl-s the added 35 HP? I was thinking of getting headers / CAI but wondering if its possible to put some TL-S parts into my 99 TL first, since the type s' enjoy a bigger HP gain from headers/ CAI then the tl-ps do. Would this work, or does the layout of the engine bay change on the tl-s, making this impossible?

 

headers would definitely help a lot. A TL-P is never going to get up to the speed of a TL-S. Sorry!

 

Although I understand your sentiment, never say never as there are plenty of things that be done depending on how serious your are.

 

what are you talking about? I would say having a CAI, Headers, CT Exhaust, UR Cranks, VAFC would get you pretty much head to head with a TL-S.

I have a friend with a 99TL and he has all of the above. We went at it, and he was very close to me the whole time. I took him by about 1 car length off the line, and he stayed like that till about 160. His car fell asleep at 160 and mine kept going, but I would still say he's just as fast as me.

All he would need to smoke my a$$ would be a Comptech SC, and a 50-75 shot of NOS and he'd be spanking my a$$ on any aspect.

Never say never...

 

higher compression,2 stage trottle body(2nd butterfly opens at about 4k rpm), redesigned air intake and filter box,plus other internal parts just cant remember right now

 

There is a larger throttle body, 2-stage intake manifold, larger exhaust pipes, higher compression, don't even start on the suspension differences...etc......

 

Wouldn't it be less expensive to just get the TL-S, as opposed to the extensive mods? You would still have $$ left to mod the type s.

 

Oops, my bad, I was thinking getting a TL-P up to a modded TL-S. My fault, I didn't write that very clear. I guess I was thinking my car. Unless it's Nos'd I don't think a modded TL-P will be up to speed with a modded TL-S. Does that make more sense? my bad, sorry for the confusion.

 

So higher compression requires the tl-s engine right, it wouldn't be some easy mod? what about the larger throttle body, and the 2 stage intake manifold, can you put the tl-s ones of those onto a tl-p? It just seems like a waste to add headers / CAI when you get the same amount of HP from the tl-s parts, then have an even bigger increase of HP when you add the headers / CAI. I guess if it was easy / cheap people would already have done it, but I thought it might be worth a shot.

 

For a price just about anything's possible:
For the higher compression you'd need new pistons ($$$), or maybe you could shave the head but then you may have timing belt issues. I would think that in order to properly use the 2 stage intake manifold ($$$) you would need the Type-S computer ($$$); isn't it a computer controlled butterfly valve?
I don't know for sure but these are some considerations I think you'd need to make.

IMHO, it'd be cheaper to just get a TL-S and upgrade further.

 

Along with the Type-S pistons you'de probably need a new crankshaft. Remember, also, the Type-S engine has cylinder liners in the block.

 

sell the 99 Tl and get a Tl-S and then mod the TL-S.

 

This would be the most simplest and easiest way.

 

i would do the 3.5 upgrade !

congratulations, you are the first to break the 150mph governer on a tl. seriously though, did you find a way to override the governor?

If you're going to spend money on mods to be close to a Type-S output, why not just go to a wrecker and see if they can score you a CL/ TL Type-S motor. Or better yet a 3.5 MDX engine (better torque). I'm sure there's some out there.
