My machinist has a 7m crank that he's going to clean up for me. My old one had a keyway that was wobbled out due to a loose pulley. He's says he's going to turn both rod and main journals ten thousands to clean it up. The crank he has has a bad rod journal, and a questional main journal. He...

Is there anywhere other than the dealership that I can get a woodruf key? I went to the auto parts store and they sell that variety pack of keys... and I bought one. :3d_frown: None of them really have a good fit. They thickest one still wobbles a little on the pulley. Do they ones you...

I'm basically gonna go with my T4 T04e "57", and hopefully make around 450rwhp with it. I don't expect to make much more than that. Is balancing the rotating assembly worth the money, or not? It's not like I'm trying to spin this 7m to the moon. Yeah, or nay?

How in the heck am I supposed to remove it? It's a 7mgte block from my '91 Supra. I don't see any nuts/bolts holding it down. I tried tapping on it with a hammer, but I was too afraid of damaging it so I did't continue. I'll see if my pics come up. Here a pic of the tube that's located...

Would I have a clearance issue with the SSAC manifold if I put an "on center" turbo on it? Will I need an adapter to clear the shock tower? Another question while I have your attention. Is there a general rule of thumb when choosing a wastegate? I've seen 35-60mm WG's. Is there a such...

Looking through some of my Mopar parts to get it up and going. I decided to snap some pics of the two pistons and share with you guys.

If I were going to just replace all of my rod and main bearings with standard sizes, do I need to do the whole plastigage/micrometering process? I've been reading up on TSRM http://www.cygnusx1.net/supra/library/TSRM/em/EM_69.html , and they show the how to check & determine wether your...

Please list your turbo, boost, and if possible your rwhp. This would really help me narrow down which turbo I should be after. I would like anything over 500+rwhp, and need to know what turbo would get me there. Race gas or not. Please help me. I'd really appreciate it. I found out my...

Is there a significant increase of horsepower by using a 4" inlet compressor housing? That's it.

I was plugging in some number in some compressor maps. When you start pushing off the map (to the right hand side) does that mean that turbo will only be blowing nothing but hot air? It's no longer efficient, but does that mean your power will drop like a rock? Would I need move to the next...

Could I mess something up doing that? I'm trying to identify my turbo and was asked to measure both inducer and exducer to get a definate answer. By removing the compressor housing could I ruin the turbo? Do I need any special tools, or will the common wrenches do?

I was looking for a good street turbo. Something along the lines of a Garrett 60-1 with a turbine at around an a/r of .58-.69. I was talking with an old acquaintance that runs his own fabrication shop. He told me it was an older (around 3yrs old) Precision Turbo that he pulled off a friends...

While tearing down my motor due to low compression in #1 cylinder I found what I suspected. So fragments of metal were floating around in my oil. Cylinder bore looked ok with very light surface scratch marks down the bore. Minimal overboring would probably clean it up. Time for some...

Any other site out there that I can host my pics? I have some questions to ask the technical section some questions, but it always helps to post pics too.

I really don't want to beat this dead horse, but i'm looking into buying a head gasket soon. I'll be running a 60-1 .60 a/r cold side, .69 on center hotside at around 25psi. I just might get guttsy and push it up to 30psi. I'll hopefully tune my car to around 500rwhp. Now i've heard about...

How long of bolts do you recommend I should buy? 1" longer than stock? 1 1/2" longer? I want to make sure my engine doesn't fall of the stand due to its weight. What kind/size bolts have you guys used? Thanks. EDIT: I guess what I'm trying to ask is how far do the bolts thread into the...

for some reason i did something to TSRM online so i cannot see anything... text or pics. so i can't refer to that. Hayne's manual doesn't really tell me how to remove it. I'm assuming you have to remove the shift fork before seperating the tranny from the engine. is there some kind of write...

Is the woodruff key (WK) supposed to fit on the crank pretty snug? the WK slot on my crank is really worn out. I can wobble the key left and right really good. oh, and the dampner was pretty easy to wobble off the crank snout. is this a sign of bad things?

I have a precision turbo 62e .60a/r compressor & .69a/r T4 on center turbine side. I was looking in to getting one of those Megan Racing SS manifolds when the revised one was done and in store. I have another route i'm looking at taking. Thought about having MDCmotorsports me make a T4...

some specs of what i should be running. already have a Precision turbo 62e .60a/r compressor 3" inlet 2" outlet, .69 exhaust T4 on-center. picked it up used for an excellent price... couldn't pass it up. i plan on running around 25psi on this unit. Picking up MAP-ecu for fuel...
