Given the $2350 difference in base MSRP from the TL-P to the TL-S, what could you do with the extra $2000 (deduct a little for the 17 in. wheels, etc.) to make the TL-P turn as much or more horsepower and torque as the TL-S?

Can it be done? Can this group beat the Honda engineers?

Forget about the exotics like nitro or pulling all of the sheet metal to reduce the weight. Answers must be something reliable and maintains the integrity of the car.

You can get Cai/headers/exhaust to get nearly the same HP as the TLS, but with all the mods you spend, you might as well buy the TLS.

Go with the type S.... with all that stock, plus wheels, and Vehicle Stability Assist, etc. Just my two cents.

If you check edmunds.com on a 02 Type-S and TL-P both in the same condition and mileage when buying or selling the difference is about 500 bucks on resale value!:bigun2:

randomwalk101

With type S, you get perforated leather, VSA, wheels, suspensions on top of the engine...a lot more than $3000 difference if you were to do it to a TLP afterwards.

Plus with the TL-S, all that power is under warranty. To get a TL-P to the power of a TL-S, you're risk your warranty. At any rate, the TL-S has a flatter torque curve than the TL-P, IIRC.

Gilgamesh

If you want to try and put all the S parts on a TL-P, for less than $2000, fat chance. You can do it with other stuff, like people said, but if you are gonna stay at the TL-S level of power, get one of those, if you want more, you can then mod the TL-S with the I/H/E

Allout

A TL-P with I/E/H will get close to a TL-S but you're topped out on what you can do. TL-S has a higher starting point and lots more potential. For example, headers for a TL-P are only worth 15HP at the top of the RPM range. TL-S gets 25-30HP for the same mod.

agean

if power is your only concern, im sure it can be done.

but, for the relatively small money difference, you get the 17in wheels, the perforated leather, the better suspension, the extra hp, vsa, AGEAN BLUE PEARL, and the really cool shift knob

best money i ever spent

I notice most of the proposed solutions are exhaust system based... good start but quite inferior... we have an experiment cooking in SC that I'll keep you posted.

I initially posted the question because my shop in SC has bumped two 2000's and 1 1999 TL-P from 225 hp to 293 by shaving the heads 2 1/2 degree from tdc in a geodesic radiant pattern and installing a high output r/t cam. All of the cars came in due to broken the timing belts and required significant repair, but we figure (my senior mechanic has 23 years of exp. with Honda) that we could do the same job on a non-timing belt job for $799.

But to be fair, we tried the same cut on a TL-S from a friend of ours and was able to generate 300 hp on the dyno. It's not as big of a jump in the TL-P, but it's more overall. We think the higher initial compression and manifolds of the TL-S doesn't lend themselves to the higher percentage of output as the TL-P. Both engine mod realized a 5% increase in fuel efficiency.

Nevertheless, maybe we'll get lucky and Acura will pick-up our mods in the 2005 versions.

HOLY JEEZ!

You increased hp from 225-293 with less than $1000. If I had enough money I would be asking how soon I could bring my car down to SC.

Seriously parts and labor only cost $800? And an increase in fuel efficiency?

Am I dreaming?

AndySara

(my senior mechanic has 23 years of exp. with Honda) that we could do the same job on a non-timing belt job for $799.

I hope he does not have a family.....cuz if the performance gain is real, he will be working 18 hours a day doing the mods for a few thousand TL-P's.

Let us know when you are ready !!!

1999TL

are you joking? cuz if not, i'll do that mod to my TL.

2ONPAR5

I should clarify... $799 covers the cam and related parts and NOT the 18 hours of labor. I was wondering if people thought the MOD was valuable enough to shell out the $2K difference between the TL-P and TL-S.

agean

okay, let's move past this "$2,000 difference between the tlp and tls" cuz its pretty irrelevant. no ones going to go to the dealer and buy a tlp with plans of upping the power to tls range by driving it to SC.

1) what would you estimate as the total cost, including labor?
2) does anyone with a little better mechanical knowledge than me know of any downsides with the work this guy is talking about?
3) i'd assume this would pretty much nullify acuras recently extended tranny warranty
4) how does changing the cam effect vtec?

sounds like a good plan, keep us posted on any further developments.

ps..not trying to be a d!ck, just trying to get some details

Gilgamesh

That further bumps the compressoin, doesn't it? Acura bumped the compression in the S by using a smaller head, or domed pistons or both? I think that the TL-S and TL-P cam is the same.

patrick

This mod has excellent potential....anyone here wanna be a guinea pig and report back on this mod after its done? Like one guy said, if this mod is for real, lots of TLers will be lining up to get this done.

Eternal TL2k3

i want to see the dyno charts for this

njzprettyboy

believe it when i see it !

Davediego

got any dynos to back up those #'s?

NSX4dr

I always have said NITROUS and I stick with it.....

Davediego

bump.
2ONPAR5 - can you give any more info about your mod or a dyno for it??

2ONPAR5

As soon as we can package it without giving away the store. We got to get a web site going and possible license out the mod to other mechanics around the country. More to come.

Davediego

sounds good, be sure to post on www.acura-cl.com people on that board seem to be more performance oriented than here
flame away but you guys know its true :o
