i have just installed 10:1 pistons & rods, well see how it goes.
theres no better reason for an engine swap than a blown motor
specially after rpm_ruffryders revealed the 4G64 swap is very possible

Got my Zeitronix wideband on the way, so all that's left is a fuel pump, intercooler and some hoses and then it's install time.

do you think the intercooler is going to be enough to keep the heat down and detonation away? maybe a water sprayer or even better a nitrous spray on the intercooler? because that is going to be alot of heat. then you could set it up to spray at a certain rpm,where ever your getting the most knock. just a suggestion.

It should be fine, I'm not running a lot of boost (only 6 PSI) and I'm having it tuned conservatively.

Why are you guys going this route? Search the net for the Cyborg w/ a G92 MIVEC + turbo . . . all that flash in the pan, and the owner didn't make the car last long enough. Street DSM'ers + Supra owners don't go this route, unless people are calling them dumb.

As for the Audi TT CR, it's tuned from the factory. Big difference from garage tuners.

Listen to DSM'ers . . . blowing multiple engines isn't fun. It waste a lot of time, effort, money, blood, and sweat. This isn't the ideals like a badge of honor.

I'm doing it because I don't have a choice, I've had high comp pistons for over a year now. I talked with Rob about it and seeing as how I only uped the compression to 10:1, it should be fine.

ok, its not like we're running 12:1, it is only a .5 raise in compression, googling your search for Cyborg w/ a G92 MIVEC + turbo came up with nothing but another of your posts, DSM'ers and Supras dont go this route because they run insane amounts of boost, not 7 or 10 psi

If your post is only to say dont do it because these people dont, then plese dont post ....

"If your post is only to say dont do it because these people dont, then plese dont post ...."

This is a mighty cop out answer.

Such margin for error is very slim than having boost creep. Ex: weaving in and out of highway traffic at 80 mph is vastly different than doing it at speed of +120 mph.

I just don't want to see another HobieK-like ordeal . . . a virtually dead car that you're sacrificing your soul in order to get it running again. Stuff happens, just ask him! When things go wrong, the engine tears itself apart.


As for the Cyborg G92 MIVEC w/ TC . . . it's the fly.to/mivec site , but those bozos have been redoing their site site since 2000 or 2002, another virtually dead site.

If high CR + Turbo was so GREAT, DSM'ers + Supra owners would have been all over it. Hell, H&A owners would have followed suite in its hey day. That's what I'm saying. Garage tuners do not equal to factory engineers or racing programs from sponsorship.

We understand that. But when you post just to say "no one else does that!", it kills people's individuality.

Hobie is the perfect example - yeah, he had a nightmare of a time, but people learned a lot. He was one of the few people to actually say "you know, this RRM kit just doesn't meet my needs. I'm going to try something new."

It's like how everyone bashes people that suggest motor swaps. If we just keep bashing these people, no one will ever try anything new.

That's his point. You make fine points about how it's not the greatest setup. But as Nick has already said, he's already got those pistons so he's now working around that to accomplish his goals.

I'm just saying "know your risk and be ready to pay the piper".

IMO, Hobie's setup is fine, but I'm assuming there was a mistake somewhere in his plan that he didn't anticipated. Then, things fell horribly wrong downhill. Like in the "Red Green" show, I'm still pulling for him to finish out his project.



"it kills people's individuality"

That's not my point. It's like someone saying "I want to put a quad-turbo setup like a Bugatti. If others don't like it, you're a bunch of haters". Or "I want to drop a crate 302 motor or a modern SC'ed cobra motor into a lancer. That's an awesome project." This is nuts w/o any sort of reality.


There has to be some sort of check and balance. People can follow Prench way of thinking: "Everything is easy, because you don't open your eyes." This way = sweet talker.

Or my way: "Bad stuff can happen, but you can buffer it to some extent if you can somewhat predict it and plan for an escape route." Otherwise, people would be running around like chickens w/o their heads. There should always be a counterpoint, unless messing around w/ H&A products.

I already know the risks which is why I'm not cutting corners, save for not dropping the compression. I already have the RRM piggyback to tune it (and I'm not doing the tuning, a professional is) and I have my Zeitronix wideband with EGT and boost sensor on the way. I never said this was the best option or even that I wanted to be unique, I'm doing it because I'm just working wtih what I have. If you have any actual criticism or maybe some idea of what we should look out for, feel free to post it.

^^^

As long as you know your risk . . . most people don't even think that far. They keep piling on mismatching mods, half expecting gains like some sort of Gran Turismo. Now, I just shut up.

Well I've already had one engine mishap (hence the pistons), I'm taking every precaution not to have another. I figured that since my wastegate is set to 5.8 PSI, due to the increased compression (from 9.5:1 to 10:1) the engine will act as if I'm running 7-8 PSI. Is that a reasonable guess in terms of equating my setup to someone running stock compression?

bahamut - Extreme examples do nothing to help. I'm not saying we should encourage anyone to do anything they want. I'm saying that if something is a little different from normal, we need to stop crushing it without asking questions.
