Cracked block/head? Sounds to me like a fresh rebuild or recondition would be good. Are you sure its "white" smoke and not "bluish"? Any whos got your work cut out for you, is there water in your oil (milky)? Good luck.

Is the ECU part# 8625? How are the Capacitors? Somthins fishy here...

There are two places you need to wire to set base timing. First one is by the drivers kick panel. Where you plug in your datalogger. Jump the top left with the bottom right (if I remember correctly, someone jump in I dont have my book with me so this is from memory) and the other is a jump...

Ah... so the same with urs? .58 A/R is fairly small so I was thinking this was the turbine side in a hybrid. I know the smallest compressor housings on the pt67 is 3in inlet with 2in outlet the others have a 4in inlet and a 2.5 in outlet (to4s housings) both of which would pbbly be at least...

Explain T3/T66? :confused:

Thats a nice curve on that dyno. Note how the torque curve drops at around 6300. Dam hybrids. I bet a stage 3 wheel clipped would adjust that torque and boost his hp, or a bigger a/r on the turbine. Wont leave much room to shift but just a thought. I like how it jumps from 200hp to 500 hp...

Dunno if this is in the right thread you might actually get a better response in the performance forum since there isnt much people that look here (comparatively). First off does the car do this only under boost, full throttle? Or does it do it all the time? I think more precise details would...

Garrett and Holset are the two geniuses behind this design. Garrett uses oil pressure to activate a mechanism that adjusts the angle on the turbine vanes, while Holset uses an actuator to adjust the volume of the turbine housing. Both are excellent in what they do... reduce turbo lag. From...

The compressor map is awesome for the T66. It is has a much larger efficiency island than the larger T-seiries turbos probably the best of em all. But for a 2 liter engine you will need to rev hard and turn up the boost alot to make 650 hp. For instance at 7k your barely getting past the...

I know on a 1g its near the left side of the intake and the connectors are attatched to the same harness as the coil. Your compression is horrible and I think its time for a recondition or rebuild. I would take a deeper look into your fouled plugs. The condition they are in says alot of whats...

Dunno if boost or no boost will change the performance of any intake. From what I understand the only difference boost brings is air density. Higher pressure brings more air in but doesnt change the physical properties of gas, it will still react the same. Does that really change things like...

Guess ya found something worse than crankwalk!! LOL thatl make ya switch back to a 7 bolt. Suks it happend to u, thanks though for sharin that.

Good info... cant wait to play with my EMS!!:D :thumb: :laser:

Alrighty... ground wire electrical tape. Id say make a tech article about it likely it will help some one down the road.... or prove our point, either way information is always the key to a better lifestyle. :laser:

How bout an intercooler and a freer flowing exhaust for starters. That large a trim will have some high demands. I would make a plan as to how much air you will be flowing with this high trim and choose your injector size accordingly. Cuz with a stock engine upgraded turbo bigger injectors...

Funny you mention this cuz i was at the junkyard the other day takin the crank out of a G64b and I saw a 90 eclipse na with an engine code of 4g67 and had a Cyclone emblem on a single runner manifold that was smaller than ours. This probably the 1.8 version i think... never seen that engine before.

Ive had bad gas in my car B4. I go to shell more regularly now cuz of it. Enigma does have a point. Timing retard is important on forced induction, cuz it is so environment-sensitive. Gas is only a small portion of it. Its there to help reduce wear and tear, removing a sensor is never a...

The whole deal about cabon composite breaks is that it dissipates heat very well. I think who ever said that its useless till it heats up was probably thinking of kevlar brakes. Carbon brakes on carbon composite rotors will work under any condition hot or cold. reason why they are extreme...

The Cyclone intake is really a tuning tool more than a HP product. It flows about 1% less than the USDM but produce more torque in your low and mid range areas, in the right hands of course. I use one and built a voltage comparator that operates it fine, with a few bugs, but love it.

I think the radiators and clutches are a carbon composite material, different than carbon fiber, but same principles. Great heat dissipation, awesome under stress. Sure design and the complexity of MASS PRODUCTION is something that has driven the price of CF components, since most parts are...

True making anything outa carbon fiber isnt for the DIYers, but props to the man that can build CF. As far as the structure goes, any harsh road condition can bust a weld on a sheet metal intake or any fabbed weld job. The benefits of carbon fiber is that its also flexible. Another reason why...

Well I spent 4 hours taking the crank out. But I am still wondering if this crank will work. Are there numbers on the crank I need to look for? Any help would be nice... any help

Wow OEM coil pack for 180 bucks. Got a mitsu part from the dealer for 70.00. LOL. If that dont tell u nuthin...

After doing a search I found that the g64b block can be used with the 4g63 head. What I would like to know if the crank can be used with the 4g63 block. I found one at the junk yard today and wanna pull it tomorrow. Any hybrid pros info would be appreciated. Thanks in advance...:thumb: :laser:

A sheet of carbon fiber that is 72" by 50" is under 40.00. Carbon fiber is much more durable than steel, comparitavely. They even have carbonfiber half shafts that are used for high performance hondas. This is not a bad idea. I would expect the manifold will weigh much less than ur magnus...

T off the BOV line. This will be set at what the boost pressure is in the intake. Any where else could give you an inaccurate response. Also is the BC home made or aftermarket. If its home made the screw and the spring need to be set properly. I had a problem where the spring was too soft...

I was pondering the same issue... ram air does slow down high velocity air to make air more available.... a free flowing intake. What if you built a front facing cold air intake, about 4-5in tube, with a nice HKS high flow filter. This would help reduce the pressure loss between the filter and...

I found a link a buddy o mine pointed out which will help prove his explanation... http://flow.netfirms.com/prandtl/index.htmI used this and found out that to increase pressure at the intake 0.1 psi we would need to go about 78mph and to increase pressure to 1.5 like the magazine article...

Hate to burst bubbles but he is right(Chres). There was a point being made about the ram making low velocity air available for the intake thus getting rid of the venturi effect. This would benefit those whom have a cold air intake pointing downward, by changing the angle and making a catch to...

Now they use high impedence injecotors right. The website mentioned them but didnt talk much about application. They didnt say any thing about which impedence. Do they support both?

Thats a nice link. I would definately have to look that up, I have a fluid dynamics book here... need to check his info. Still a lil skeptical about the application, but I can almost understand his statement. Thanks...:laser:

Thats it! Thanks! Nice website by the way extremely informative!:thumb:

The design that I was looking for is a standalone system that controls 4 injectors. Not a piggy back design. This one was relatively cheap too. about 300 new. thanks though...

I have read a post about a month back that had a site that sold additional injector controllers. I wonder if any yall know where I might find that site. The thread was about mounting injectors on the backside of the manifold and some one used this controller to manage the additional injectors...

I know if a turbo has been professionally rebuilt it also gets balanced. They take some metal off the hub of the turbine as well as portions of the blade. If they had to send it to two different places in two states, tells me they used their sources and took care of makin sure it was done...

ya dont forget to strap about eight fans to that hood!! lolI would honestly worry about pressure drop. if its too big it may loose alot of pressure after the turbo. Especially if it isnt an IC designed for sport use. I have seen people weld ICs together but dont have the same gains as...

The shape of the intake may effect flow, but the real gains in a short runner/ high volume intake is taking advantage of that rarefraction wave. If you have a large plenum, there will be enough air there to scavange its next draw. If the wave has to go through the TB than its lost never to...

Which is the power TR unit right... so if i hook up another one... vioala! True COP... up grade my valvetrain add bigger cams and I will see what 10gs will do to my engine...MUAHAHAHAHAHA!!!....anyway...I love this post

Another cool thing you can do with those numers...PR (before ram air) = (18+1+14.5)/(14.5 - 0.5) = 2.4 PRAfter Ram air = (x+1+14.5)/(14.5+1) = 2.4Lets do it this way to see what kind of boost gains we see at the same PR and shaft speeds.(x+15.5)/15.5=2.4x+15.5 = 37.2...

I wonder does the AEM EMS have the drivers to run COP on the DSMs? I hope so gittin one soon.

holy smokes... what kind of throttle body do you have on there?! nice git up!

So its basically same coil system, one coil firing two plugs simultaneously. If thats the case than the 300m COP system is much better. I would stick to that. Reason being is that the coil has longer periods to charge allowing a more consistent spark as the rpms go up.... wait a minuite...

This sounds awesome... what does the double ended have to offer that the single found in the 300m that most ppl with this are using. Is it faster or more powerful. I would definately do it if your building a high revving engine. COPs will rev 10gs or more from what I understand, if the double...

I love this forum... had this been placed in a different forum on this site he woulda definately been flamed. Anywho, the rear of an AWD has independant rear suspension. that will take alot of room and will need to be fabbed too if you dont want the stock trailing arms ripped off. Remember...

High VE's will be found on top feul cars tuned for very high speeds. This will keep the cars on the track longer with less pit stops. I wouldnt doubt they reach 130%. To clear one thing up is that the PR for a turbo on the compressor map is the ratio between the impeller and expeller, turbine...

Nice thread but try using numbers with the larger turbo without the VE at 110%. more around 85-95%. Turbo cars will never exceed that. Doesnt matter how well the head flows. Also you do have a point, but most people buy larger turbos for higher boost levels. It would be downright foolish...

I am under the assumption that the GM MAF has some way of measuring boost as well as flow for this to work post turbo. I am not clear as to how a hot wire MAF works vs a Karmen vortex. I know the Karmen device uses the vortices through the honeycomb to measure air counts. Is the hot wire...

you will need to get the pin out for the jdm ecu. Ripping out the harness sounds like a big job.. but not much to it once you get into it. I put feul injection for a carb engine on a 75' celica and had to do a harness swap. not too bad. Took 4 hours to complete it though. I still think...
