Zeus,

No sorry, I had it jotted down to answer, not sure how I missed it.

We are not going to do a water cooled housing. The EVO has a MASSIVE oil cooler on it. The car comes with synthetic oil in it and is recommend to run nothing but and to have frequent oil changes. There are going to be NO problems with a non water cooled housing.

I have been running NO oil coolers, NO water cooled housings and NO synthetic oil in 4g63's for about 10 years now. NO problems with eliminating the water cooling.

Getting this housing built in a water cooled unit MIGHT be possible. I am not going to offer it BUT if it is the only was you or someone else would buy the kit I might check on it. The water lines might not be that hard to make work from the stock turbo.

What I am telling you though is they are definetely NOT needed, you have my word.

David and Tym, please don't get discouraged. You guys obviously know what you are doing and I don't doubt for a second that when you get a chance to run it that all doubt will be erased. From your experience is this about the limit of pump gas or do you think that there is much more to be had? The reason I ask is that if this is about the pump gas limit then I see no need to run a larger turbo and loose the exellent spool characteristics that you have right now. I would not be suprised to see a little bit of an improvement with the 272/272 combination and look forward to a run on pump with that combination. Due to your findings on the stock springs and only due to what you have said I have already installed the Works springs and retainers on my car in preparation of the higher RPM breathing potential of the 272 cams. I sure as hell do not want to tap a piston when the ability to insure against it is so relativly cheap. I am looking forward to seeing where this all goes.

 

Dave - don't forget - I got my order in 1st I belive ! I'll take that 475 !

BTW - IF I wanted to swap to the 550 do I need to get differnt pipes or is it a direct bolt in ?

 

your right david, it does take around 400hp to run those times. however, you have awd, that skewes things abit. you SHUOLD be making that power with that you have done.

i said it wrong before, what i meant to say is that it CANT be compared to what we see on AWD dyno's. compare apples to apples.

i would gladly build and evo to run whatever you want me to, but i dont have the $ to do it. im still in college and im working as much as i can get my prelude finished.

id also bet to say that you are probably quite a bit better driver than the normal person. i have no doubt you would drive an evo faster than i could... i drive fwd cars... a completly different beast on the track.

how bout i bring our STOCK block b16 powered hatchback to the track and see how your 400hp stacks up to our 300?

 

What kind of prelude you building wadzii?

 

its a 92 prelude s 5spd. currently its sitting with out a motor.

i have a F20b from a 99 jdm accord sir-t waiting to go in.. the f20b is a 2liter (85mm bore x 88mm stroke) 11:1 compression dohc vtec motor thats rated at 200hp, 145tq

im working on building some ITB's and my own custom header for it. it will have some big cams, im still researching on what i want to go in there. im looking for around 225-235hp NA and i want power out to at least 9000 rpms. oh, thats with a stock block and head, i dont plan on taking the head off till it blows up.

i have some jdm tein HA coilovers for it and im gona do some other custom stuff noone has done before. its gona be an all purpose car... drag race, track ***** and daily driver, and of course it will have an AEM EMS in it

The Evo would come by you so hard that you would have to put an oxygen mask on the engine to keep it running.

All in good fun. Have a good one.

 

Basically, Your "word" is enough for me to "settle" for a non water cooled turbo. I only say "settle", because if one were to look back at all my arguments on the Evo, one would see that I'm arguing on the side of caution... bigger injectors, bigger fuel pumps, a turbo that can be tuned safely on pump gas (so you know its good to go on race if you want), etc, etc. Over kill has been used more than once following my statements. The reason I'm so concerned about the Evo is that people are seeing 250-280 degree operating oil temperatures on next to stock cars. Thats pretty warm... esp since you can bet that the oil temp coming out of the turbo is way beyond that. Now again, I'll put my money on your 15 years with the engine before anyone, but just to tell you how **** I really am, I'm already sourcing a larger oil cooler core for my next to stock Evo.


As for all the people *****ing about dynos... seems no one has come close to doing so much with so little as Buschur when it comes to putting the power down (I'm not talking about dynos here). I'm a firm believer in the old saying that respect is not given, but earned. David has earned quite a bit... I'd go so far as to say more than anyone else in the DSM world... 10s,9s,8s,7s. As much as I'm not a quarter mile man, it is a good measure no less. I've used "over 400whp on pump gas" many times as my goal... That looks like a mistake many have made... I guess I should have just merely stated I wanted enough to take that certain German car I have my sights on. I'll be willing to bet Buschur can get me there without sacrificing any drive-ability.

 

Dave when I get my 04 RS I'm willing to drive all the way to wakeman Ohio, from NYC for the full Stage 4, and BR475 kit......

keep the goods coming

 

God, i hate beeing left out......why cant we ever get 91 PISSTANE gas numbers. CA/AZ bites the big one let me tell ya...... do they really sell 94 at a gas station???!!!!! That would be race gas here...!!!!!

 

... sucks... sorry, it's a little funny...

 

we can get 100octane at some pumps here

 

I give credit were credit is due, and I can't say enough about BR and how their products perform. Thanks David for clarifying the fact that final tune was not done when you ran that dyno test. I beleive that the BR475 sounds like a wonderfully spoolin turbo, stock like, I guess after seeing other guys make 419whp on a AWD dyno on pump gas (some guy in FL) I was expecting something similar. I guess the bigger turbo will put out big time numbers. By the way, 365-75 whp on a dynojet has been put down more than once, ask the tuners. Very impressive and clean looking manifold Question: will the kits with the bigger BR580 cost anymore?

 

Couldn't agree more Dave & Tym...I almost feel bad? What some people on here probably don't know is that I've been reading these type of post for over 6 years now (since I first bought a DSM) & here we are in 2004 & they're still having to prove themselves, their products, & results Dave Buschur practically started the DSM movement all together! What more do you need than his word...the answer is nothing. When someone from BR talks, if you were smart you STFU & take some notes Keep doing what you've always done to become so successful & let the nay sayers learn the hard way.

Truely, for 75% of the people who race ANY type of DAILY DRIVEN car, 400WHP on pump gas is about all you really need! People get too focused on numbers but don't understand that results are far more important. Besides, daily driven vehicles aren't half as fun to drive when the practicallity & reliability are removed from the equation. Think about it.....

 

Blue Evo 8, I'd drive from calif. (the land of pisstane) but with Buschur's stuff you don't need to! I'm at a flashed stage 4 and the only thing I paid to have installed was the cams (which got messed up, and I had to show them how to retime it right, but noticed before any damage was done)...All in the driveway on blocks (and because I'm old and Fat they're pretty big blocks) I did have a small hick up with the exhaust but only cause I didn't read all the directions. If I had, the 3x re-adjustments to avoid rattle/vibration would have never occured. I've had 3 exhausts on this car and the BR is by far the best fitting (defined as highest/best ground clearance) dragged both of the previous exhausts... with the BR I'll drag aloy of other things first.
