Well, I bent a rod and locked up the engine. Since it's going to be torn apart and get new stuff, I might as well re-inforce it like no tomorrow. I'm looking into buying the K1 rods from Dezod, as well as the 8.8:1 comp pistons. Does anyone have some feedback on these pistons/rods, I know Dezod makes great quality parts and they've got the reputation to back it up, but I was wondering if anyone knew the real limit for these parts.

Also, does anyone know any places to get a short block? I'm not sure how much/if any damage has been dealt to the cylinder walls, so I might not even need a new block. I know I could get one from the dealer, but odds are, it would cost an arm and a leg. I even considered just swapping in an easy to find motor (like a B1

but then I'm going to run into huge compatibility issues and it would cause more of a headache and cost more money.

Any recommendations will be helpful, thanks.

Whatever you do, do not swap a honda motor into a tc, unless it's a 3.2l NSX v6. Best bet is to find a block in a junkyard or on the forum. Or you could just do that NSX swap...

davedavetC · 02-05-2008, 04:37 PM

just build the stock motor, idk why you would even consider a b18. thats just wrong.

are you gonna boost it? because you will LOSE power if you stay NA with those low compression pistons. if you dont plan on boosting anytime soon get teh 11:1 pistons and build it NA

**Ace83** · 02-05-2008, 04:39 PM

dont do engine swap, just build the tc motor.. go to junk yards if you need a new block or you can buy a built block

**Ace83** · 02-05-2008, 04:41 PM

yeah you will not benefit on low compression piston if you stay NA

It's a great motor, but like I said, I'd run into hundreds of issues, I just named that motor because I can get one for about 2k...

. If I was serious about doing a swap and going into some real custom shiz, I'd do a 20B

. But yeah, I'm NOT DOING A SWAP lol, I was just talking out of my ___. I need some feedback on those pistons and rods, I'd really like to know how much HP/TQ the stock motor puts down with the 8.8:1 comp pistons and just those pistons, but that's way too much work to do lol. I had a dyno-sim program at my school which was only 2 HP and 400 RPM off from what the tC specs were and 3hp/-700rpm for my quad's specs, so it was pretty accurate.

davedavetC · 02-05-2008, 04:55 PM

you will lose hp and tq just slapping on low compression pistons.

and you never answered my question

are you planning on boosting it? either sc or trbo?

Yea I know how compression works, that's why I want to drop it

.

**Ace83** · 02-05-2008, 05:48 PM

you can still get forged piston with compression close to stock, its still stronger.. and hey when you have a built engine doesnt it bother you that all you need to do is slap a turbo? haha you might go FI along the way

engifineer · 02-05-2008, 05:59 PM

I am guessing your answer to "are you going to boost it" is yes based upon your last answer, or you would never consider dropping the CR, since it will downgrade the stock power.

As for the short block, try car-parts.com . It will be a salvage engine, but you can probably find it listed near you and get it gauranteed to run. Since you are going ot rebuild anyway, you will be getting it honed before you install your pistons, so a used one isnt a bad choice in this case. Just have the machine shop check it out well before you put it in and make sure the salvage yard will cover it.

I have heard of short blocks going for approx $700 - $1000 for the tC in the past, so I am sure you can scrounge one up for that.

djafropiq · 02-05-2008, 06:30 PM

someone was already selling a sleeved block in the PPC's for like 750 i think.. should maybe hit that up..

Thanks, since I doubt that this car will become a DD again, I think I'm just going to boost the living ____ out of it

. I just want to pretty much reinforce as much as possible just to prevent having to repeat this process. I rebuilt 3 350's, and the process is ridiculously easy, worst part about all of it is all the damn measuring. I haven't pulled a motor out of a car that needed a motor to go back into it tho, which I'm sure is going to be a giant pain in the ___. At least the tC has a fairly large engine compartment for such a small engine, not like the Supra or 300ZX.

Did a quick search and found nothing really, one was the 2az-fe from a Rav4 for $650, then the heads are between 400-600, so it's basically within the price range that I expected, $1500-2000 with shipping. Still better than the $4000+ getting a new engine from the dealer.

Its hard to say that a product is good for a certain amount of power. The two parts that you referenced are stronger than stock and with a safe A/F ratio and tune it will last for a while.

By boosting the living ____ out of it longevity will be sacrificed.

From what I have seen these are your best solution for beefing up the 2AZ-FE at this time.

Is this car going to see the track? What numbers are you shooting for?

I wasn't asking how much the rods were going to be able to handle, I was asking how much of a power loss would there be versus the stock 9.6:1 compression

. This car is basically going to be turned into a project vehicle, I had plans of doing this once it started dieing out on me...which I was hoping would be 1-2 years from now (after 1-2 years of being boosted), but I didn't plan on starting the project now. My final goal is 450whp, which from what I've seen, is very doable, but I'll be more than happy with 400. It's going to take a while, so I got plenty of time to shop around, etc...

Compression ratio affects a large number of performance factors including economy, throttle response, and bhp per psi of boost.

We have been using JE's 9.0:1 on turbo applications with no problems. There is a slight delay before the motor builds power, but with so much power at the top end you forget all about the delay.

garabaldy · 02-06-2008, 10:53 PM

What caused the motor to bend a rod ? Was it boost? if so how much were you running? run too lean? etc?

Hydrolocked.

Whoops, missed that lol. Going to turbo it.

R6isfaster · 02-06-2008, 11:10 PM

I have a 2.5L stroker S2000 motor that was in my S2k...and I'm selling it. It made over 250whp, now that would be a crazy motor for a TC

t_urbo_C_harged · 02-06-2008, 11:51 PM

don't listen to him, get a motor off of craigslist (I have found a couple before anywhere from 400 to 1500) or ebay or something, then take your current block out and get the crower stroker kit when it comes out!!!!! but that will be real expensive hahahaha

and a couple of people have those rods and are making good power, scionGT35R has the rods and was doing great with them until the bolt came off of his oil pump and went into the pickup tube... find his thread and take a look for yourself! Should handle all you want it to...
