J35A8 Procharger Engine Build

I would like to eventually build my j32 engine. For FI I would like to lower cylinder compression. I’ve read that using forged 3.5 rods on a 3.2 crank will lower compression due to 3.2L rods being longer. Is this true?

Yes, but do the math first; the length of the rods may be too short and you'll end up with something like a 6:1 compression ratio.

I figured I would just shoot first ask questions last.

Currently compiling a list of internal build parts.

- Wisco Pistons
- Crower rods
- Supertech Valve Springs and Ti retainers

Would RL cams fit into the J32? I read they are better than stock 07-08 TL/TL-S cams.

If your,going boost no need to worry about camshaft? How much power do you want to make? Also you might want to consider buffing up the transmission. . this is how much power you need to be a 10sec car. Taken from my friend built motor accord v6 mt.

1000whp to be a 10 second car?

FWD kills these cars. It's fine for ~350whp, but anything up and beyond that, I dunno what the point is... unless you like spinning your tires in 4th gear at 85mph

Then again, looking at that dyno curve... looks like he could've used a smaller turbo to build boost earlier on, with a much lower peak power value and still gotten the same times.

Curious, OP, why don't you pick up a platform that comes with boost from the factory? Then you can safely play with it, up the boost easily, and make stupid amounts of power at a fraction of the cost.

Granted, the TL is a good looking car... but dropping mad cash to build up a stock engine to handle more power, which is still incredibly difficult to effectively put down and control, why not pick up a 335i or S4 or something, throw a tune and full exhaust on and enjoy the 100hp you just gained, to add to the 100hp more the stock car already has over a stock TL?

Better bang for your buck. A shit ton of cars to choose from. Lots of good looking examples. Etc.

I mean, it's you're money by the end of the day... but there's a reason nobody really spends crazy money on modding the TL anymore.

I still drive a TL, but looking to replace it next year... probably with another 3G TL

But I won't be spending money on modding the shit out of it. If I didn't buy another 3G, I'd be looking at a new Golf R, or a 2016 S4 (last year of the manual). Nothing really else out there for me.

but look at any of the mods or OG members... I'd say maybe 20% of them still have an Acura in their household.

He's right.
Love the TL for what it is...don't try to turn it into something it's not. It's too spensive.

I’m not trying to pimp it out, or make it a 10 second car. I just want to build it to handle he 500whp I’m looking for. I am trying to only do Mors to it that I can swap into a 6mt.

Im modding my 3g because I want a faster car, but haven’t found anything close to what the 3g means to me.

Wasn’t there someone who recently put down mid to high 400hp with a RL engine swap(with mods) and a rotrex supercharger ?

I think you're trying to spark conversation, which isn't a bad thing...but acurazine already has a plethora of what if threads that are all talk and no action.

Don't forget butchering a TL to put another engine in the rear.

I’m not installing a rear engine, I just shared the crude measurements to show it is a possibility. Sparking a conversation because this is one project not yet contemplated from my search.

I didn’t do thourough enough research. Wanted a whiney Comptech SC.

May just keep the CT on the auto since it’s finished now and save the Rotrex for the my 6mt.

Im also not looking for a 10 second car Azn, I just wanna want to make 600whp on my 6mt. Whatever time that makes I’ll be happy with.

So, are you the guy from 'out of town' that picked up this 6mt?

Understood. Thanks for the response.
If it were you, I was going to suggest, based on the picture below, to hose down the S/C'er shaft and snout with some brake clean before your long drive across the country. It's a little difficult to tell with the caked grime; however, there may be a slight weep of S/C'er oil at the snout. It may also just be residual motor oil left over from sloppy oil changes. Just an observation, it's probably nothing serious.

Zeta, that rustbucket isnt mine! I put 180ml of fresh Delco supercharger oil in mine. After using loctite, I went into the shaft opening and used Qtips to clean out the risidual on the inside.

, I know.

So, no further problems with the serpentine belt fraying?

Take a pic of the CLS PS hose inlet you purchased, next to the TL one currently on the car, if possible. I'm interested in seeing how they compare.

If all you want to make is 600whp on a j35a8 then all you need to do is install oem j35a1 piston and rods. Those have held up to 900whp.

Yes sir, Aaron from Englishtown racing (I think that's the name of his place) knows anything you want to know about J series. His car has 950whp-ish on his J, he was running oem piston and rods with a stock block. Most people don't know that little known fact. But the J35A1 piston and rods are beefy to support about 700whp Aaron says. The stock sleeves of the J35A8 can support it too. All you would need is valve spring and retainers and you are good to go.

I'm really curious to know how many miles he's put on that engine. Something tells me it's not a lot.

why would the j series be built to withstand 700HP?
Curious. Not asking for a friend. I want to know.

Engines are routinely over-engineered. Think back to the pedestrian 2.2 liter "Turbo I" engine in the old Dodge Daytona; in 1984 at full boil the engine put out a whopping 140 HP; the engine itself was stressed to well over 400 HP.

Right, but you're comparing two completely different applications. Forced induction engines were normally overbuilt. Think of the Skyline engines, Supra engines, etc. All of them could handle a ton of power.

It's not normal to build a naturally aspirated engine to handle almost three times its rated power. Just because someone did it and hasn't had the engine blow up, doesn't mean it won't blow up. Often times guys build up their cars and then sell them within 1000 miles of finishing it.

Think if it this way- honda is an ultra conservative company- they are all about pinching pennies wherever possible. I am very skeptical to believe honda built a NA engine able to withstand 700hp, knowing full well it would never be utilized.
