Rod knock?

[jdub]

I have always said since I received this car the first day was that I am going to turbo out... point out anywhere in this thread once that I said I wasn't going turbo...

but thanks anyways for the luck..

You are missing the point...personally I could care less if you go turbo, or strap JATO bottles on the side of the car. You are demonstrating basic knowledge deficiencies concerning this engine. Wanting to use 272 cams and oversize valves is a case in point...you have no clue how either will affect HP or the way the motor runs. There are several other cases...like piston position vs crank position for example.

Nowhere in this thread have you posted a plan to achieve a specific HP goal...that should be your 1st step. Then list what mods you think are required...including how you intend to control the engine (stock ECU or standalone). You also have to keep in mind you are putting a turbo motor in a NA car...have you even read the NA to T FAQ (sticky) in this section? One hint...the NA ECU is not going to work. Another hint...$3000 is not going to be near enough to achieve even a 400 HP goal doing a NA to T swap.

There is A LOT to think about. Using the "all thrust and no vector" method is not going to turn out well. I'm just warning you with a dose of reality...seen way too many of these threads end in a parts sell off down the line. Of course, it is a way for guys like me to get nice stuff...cheap

crank is rusty?

you'd do better to swap exhaust cams with a gte one since its apart.

i thought it was the intake cam that was different??(little more lift) only bringing this up because i dont want to swap BOTH!! lol.

Research IS key, but remember it is just nuts and bolts
If you are goin NA-T then i suggest you READ A LOT, I would consider getting a GTE pistons also, not sure if the 9.5:1 will take 400hp reliable/DD. I'm NA-T right now at an estimated 300 @ stock boost, shooting for 400 but my guess is shes not gonna like it for long...and you'll need these.

Scrap the oil cooler/filter housing, its a big POS, IMO. Go full flow, jdub himself can elaborate. and good luck

Your right, I don't know what oversized valves is and what it's for... I'm sorry.

I know exactly what 272 cams are and what they do. I had them on my honda also. I also had AEM tru time cam gears to go along with it...

I have posted numerous times my hp goal, my plans, setup and etc... maybe you should read instead of telling me
I've also linked it to my complete and full build thread... I've posted pics and vids...

I have read that sticky...

If you read onto why I had theory that the crank position vs. pistons didn't look right, then you'd understand... and if you were anybody like me who goes from 4 bangers his whole life to an inline 6... I think you'd do the same...

If I do end up in that category, it doesn't bother me... I picked up the car for cheap... and this is only helping me further my knowledge... I really doubt anybody succeeds on the first try. (First time actually doing a rebuild for me)
But since you insist, I'd really like to finish it to prove you wrong... but thanks for the 'dose of reality' Dr.phil.

Is it possible at all for you to not come in here and down my project? If you guy's cant encourage it then just don't help... it's not hard...
I don't care how 'oldschool' you are(I think that sticky in the first place is retarded) I never act like this when I'm a regular member/mod and respected on other boards that I post on...

I find 272's unnecessary for your power goals. Stock GTE cams should be fine.

 

[Epy]

and I don't want to get GTE cams and I might as well get the 272's now...

I mean shit, when do you want me to start upgrading?

 

[Supracentral]

272 cams cause poor idle, and bad off idle torque and throttle response, lower fuel economy, and poor low speed efficiency. Overall they lower driveability, it's a trade off - peak horsepower is what you get in exchange for this. Your stated horsepower goals mean you're going to loose all that, and get back --- nothing. 272's aren't worth a damn below 650 RWHP.

You seem bound and determined to argue with people who are trying to help you, educate you, and help prevent you from making costly mistakes...

My advice would be SLOW DOWN and learn about what you are doing before you do it.

You're going to find the more knowlegeable members are starting to walk away from you shaking thier heads, and you're going to be left getting advice from people who don't know thier ass from a hole in the wall.

Do you want your advice from people who know (and have done it before) or people who say "I guess", "I've heard" an "I've read"?

If it's the former, slow down, understand where you are trying to get, and then let people help you get there. You're making snap decisions that are going to cost you a lot of money.

We're not trying to bust your balls.

Ummm...no you don't. Maybe on a Honda, but not on a 7M. SupraCentral called it dead on...and to add, exactly how to you think you will get the stock ECU to control the issues SC posted? The answer: you can't. You will need a standalone EMS to handle it...you need 272 cams like you need another hole in your head.

I have read this thread...twice...maybe you should go back and read what you've posted? Build thread on SF? Sorry, but the 8:1 moron to competent ratio pretty much keeps me away from SF.

Your HP goal is a moving target...started at 500-600HP, then 400 HP. It's obvious you've never driven a 500 HP car and damn sure don't know the cost in building one.

I have read that sticky...

Based on saying "I have $3000", it sure doesn't seem like it...or, you are completely ignoring the cost involved for for JUST the NA to T conversion. Not to mention machine work cost, turbo cost, intercooler, fuel mods, etc...JE pistons and eagle rods? There goes $1000. You're dreaming...cost is an issue and unless you have the resources it will stay that way.

If you read onto why I had theory that the crank position vs. pistons didn't look right, then you'd understand... and if you were anybody like me who goes from 4 bangers his whole life to an inline 6... I think you'd do the same...

LOL...that the difference between me and you. I've done I4, flat 4, V8, V6, I6 over the past 35+ years. I did read it and your experience level is graphically evident...denial is not a river in Egypt

If I do end up in that category, it doesn't bother me... I picked up the car for cheap... and this is only helping me further my knowledge... I really doubt anybody succeeds on the first try. (First time actually doing a rebuild for me)
But since you insist, I'd really like to finish it to prove you wrong... but thanks for the 'dose of reality' Dr.phil.

The problem is you don't want to learn from those that have been there, done that. Your attitude has simply served to cut off any help you may have gotten from the experienced guys. Please continue with the "I've heard" crowd on SF....don't forget to post the results here. I enjoy the occasional amusement.

I don't care how 'oldschool' you are(I think that sticky in the first place is retarded) I never act like this when I'm a regular member/mod and respected on other boards that I post on...

There's the attitude again...it's actually your major problem. What do you want us to do, encourage dumbass moves? Encourage you to basically throw $$$ away? When you finally figure out that the guys posting in this thread are TRYING TO HELP YOU, maybe you'll get somewhere.

*reserved for Cam Info Link*

Im sure someone else here could post a link that goes into more detail

 

[Supracentral]

Remember that Supra .272 cams are designed for use with forced induction. There is a large difference between forced induction valve timing and N/A valve timing. Most domestic articles will focus on N/A performance, which is very different.

Ah my mistake, thanks for clearing that up. I remember there being something posted here or maybe its on MKIIITech.

 

[Epy]

yea and I changed the HP level after I realized it was way to high. I had no idea what supras do and what it takes to get there... rather, I had higher expectations for a supra(Mk3 persay)

Your still not understanding my point... I don't care where you've came from or what you've driven.. I'm telling you my scenario and that's why I assumed the crank v. piston position... I understand that it was wrong and your still going on about it...

For the 2nd time, I have read the sticky... don't tell me I haven't , if I have... LMFAO

So if you think I'm doing everything wrong... here... why don't you take the one minute out of your time... put yourself into my shoes for exactly 60 seconds and write-up and tell me WHAT YOU would do in this situation...

The head is off with only the valves in...
I have 3,000 dollars with plenty of time...
I want turbo...
Have the block seperate also...
where would you go? Just curious...

A Supra is a Supra no matter what generation it is they will all perform where you want it provided you take the steps to make it happen. If a Supra is badly cared for, running even just 300hp will be a task.

Not to sound like an ass but id research first on what id want to do with the engine. Most people wont tell you what to do because they will all have something different in mind. So ill just make it simple Obviously you want to go turbo so youre either going to have to get a GTE shortblock or swap in GTE Pistons provided you can. Second find out what the condition of your internals are. You can spend anywhere up to $1400 just on machine work alone. Thats where id start the rest is going to be up to you and what your goals are. If you searched you wouldve found out that a stock internal GTE can take upwards 400+hp provided its been rebuilt right with a MHG. Someone has even made 700hp. It all depends. But like everyone else has asked have you ever been in a 350hp Supra before?

 

[Epy]

no not in a supra... I've said, I've never even dealt with toyota... I've been in a hooked up matrix that's about it...

i've been in 600 hp stangs and alot of domestic not really import... fastest import was prolly like a 500 hp nissan.
I've rarely dealt with toyota.

 

[black89t]

sorry to say but you did blow it. :3d_frown:


you would have been way better off just buying a supra that was in good shape. with your 4g's you could have a clean ass mk3 turbo. and yes you have shown you know very little ass far as rebuilding anything. let alone a 7m that takes caution and knowledge. at this point i would just drop in a $400 ge and get rid of the thing. personally i would never want to start a project where the car is that fucked up. why..........i know the cost to just get the thing looking half decent let alone nice. other than that i don't really have anything to say other than jdub has given me killer advise more than once. i would consider youself lucky he even bothered to take the time to say anything. anyway i'm going a super bowl party to get hammered. ::w00t::

SC doesnt do the engine specing. Many have built monsters (or lil girls) out of the 7m platform. You should be able to find a setup in the build threads that will fit your budget and needs.

put the spoon away, its time to read!
