So I've been hyped up about bore, stroke, compression ratio's etc, lately. And found out that the MDX (which has a J35 engine) has the same bore as we do, but just a longer stroke. (which gives it the extra .3 liters of displacement up to 3.5 from 3.2) It sstroke is 93 mm while ours is 86 mm. Well I asked an Acura Tech today what it would take to get the MDX's displacement. Well it would take, their pistons, rods, piston rings, and crank.

I didn't think the price would be bad, but it turns out that, pistons are $90 apiece, rods are about the same (don't forget we have 6 of each since we have 6 cylinder engines), and the crank alone is $500. (ouch)

The total comes out to more than I'd want to pay....

Then again 245 lb.ft of torque at 3000 rpm-5000 rpm does sound pretty nice. Plus the pistons raise compression to 10:1 (plus my mods)

On a different track, I asked about what it would take to gain the Type S compression and redline:

For the redline, it'd take the valve springs, retainers, and supposedly the valves are different too. Valves are about that $16 each (24 of them) springs and retainers were relatively cheap (but there are 24 of each of those too)... it all adds up. I would say about $600 for all the parts alone. Worth 7000 rpm to you? You decide.

The Compression is cheaper, All you need is pistons, piston rings, and rods too I think. (6 of each) They run close to $25, so I'd say around $400-$450 for all the parts. And that gets compression up to 10.5:1 from our stock 9.8:1

Whatevers, sounds like a bunch of unnecessary crappy material to me. I would just

a) get a better car

or

b) get nos

valuetl

The intake and also electronics are different on the type-S also. Another question I read alot of guys saying our 5 speed isn't up to high HP or torque but they used a 5 speed auto simular to ours in those 300+ HP accords????

lol what a classic Rice1304 post "sounds like a bunch of unnecessary crappy material to me"

Getting a better car: requires losing around 2-5 grand in the transaction depending on how badly the dealer wants to rape you on your trade in. Good grief, if I was to sell the TL to a used car lot, then buy it right back, I'd lose about $2,000...

Getting NOS: hmmmmmm how about no? I can daily drive a modded N/A vehicle and get the most from my mods, whenever I step on the pedal, whenever I'm challenged to a race, whenever I want to autocross, and especially when I want to do 5 or more runs at the strip. Can you do that with NOS? or how many times are you gonna get caught with your pants down (with an empty bottle). Basically just like any old schmuck with a stock setup that's blown $700 just to get his ass handed to him.

are all thsoe type S parts can use in our TL ? If yes, then the compassion parts sound great to me

Atomix

Both the MDX and Type S have a dual chamber, butterfly intake system, that gives them some juice too. But NOS is still the most bang for the buck.

As for buying another car....S2000.

That is a typical rice post.

An easy way to raise compression ratio is to install thinner head gasket.

no offense, but I would still get nitro...
well, rice, what's your major? Psych? guess he's doing a project about what people say about someone that's annoying. maybe not...

Good call. Do ya know anything more about it?

SilverSoCal_CL-P

I was online and found this site: http://e-automechanic.com/foreign/

Anyways, they say that in 2003 the MDX engine will be increased from 3.5 to 3.8 Liters. So who knows, maybe a 3.8 TL/CL???

interesting subject of research for me. If u can get parts CHEAP, i mean if u have hook ups from the parts department then it's all doable. it's just the labor that's crazy.

man, changing all those engine parts would be MAJOR BUCKS after the labor. you guys are on crack!!!

better to wait for a blower or turbo, or maybe just swap a CL-S engine in. or, as the venerable Rice said: "get NOS"

me? if i wanted to go real fast i would have gotten a different car, maybe a used 540i, M3, SC400, or maybe a CL-S. no, wait - i hate the CL-S. sorry!

In 2003 when Honda does make that move, they will have the DOHC Vtec V8 under their belts, and that will be an option to them, to put a (relatively) small V8 into the MDX instead of a (relatively) large V6 in it. To me 3.8 could go either way, V6 or V8.

How about the adjustable cam gears to compensate for the cam timing variation by reducing the distance from the crank centerline to the cam centerline????

All a waste of $$$ for 5-10 hp.

Hmmmm seeing as the MDX gets 245 lb feet of torque at 3000 rpm and up, and the TL gets 216 lb.ft at PEAK, I would think there would be a HUUUGGGEE difference in power, rather than your supposed 5-10 hp waste.

I'm sure the TL gets some 190-180 lb feet of torque at 3000 rpm as opposed to the MDX's 245...
