I got owned by an eclipse today.... (my car might be having probs, suggestions?)

Well first of all im not the racing kinda guy, but my friend has been modding his eclipse to try and race my supra so after work me and him found a location where there is no cars and a 2 lane street by the airport where we work and we played it safe, no jerking around, just to see where i stand and where he stand with his mods. We usually go to the track but i used to take my 240 out there but wanted to compare to his eclipse wich has a turbo, DP, exhaust, intake, boosted at 15, pushing about 270-280hp

Well so we lined up and when we took off i bogged the car and didnt get a good start it being my second time driving it since i bought it this saturday and was working on it since, with changing spark plugs and checking fluirs and brakes and such... so i have no launching experience on the MKIV. I do have a 240sx and i cant launch that thing higher than 2,500 otherwise ill be spinnin tires, so i think i reved the supra to about that and launched and bogged....

So.. We took off and he already got me off the line good, and since i bogged and it dropped to around 1k i had all the lag in the world. Once it started pulling my car wasnt really catching up, and i wasnt feeling much pull either, even tho it was still pulling because before i knew it i was already at the redline and shifted in 3rd and my friend was still pulling on me, so thats when i let off.

I got a vid of this, if anyone wants to see, id need someone to host it for me, its only like 3.5mb but you will see what im talking about kinda.

My friend matt who was taping told me i got a bad start, and zach with the eclipse asked me what happened and my other few friends who watched asked the same thing because they all expected me to win, and so did it... so i just told them all :dunno:

Back home now and i looked at the BOV hose the one that is connected to it closer to the front of the car and i saw oil there on the hose and around the house, almost like its leaking air from there and blew some oil out, since all turbo cars have some amount of oil in the airpipes,

so im thinking im loosing boost there maybe???

Also i was thinking that maybe the BOV is bad but how do i check this, because i dont hear the stock BOV, but are you supposed to hear the stock one even a little??

Also maybe some of the vacume lines are bad? but i havent really looked into that as much as i prob should.

I have changed the spark plugs and got 6097s and oil is new and clean, everything is good, shifting good, chirping 2nd gear and sometimes 3rd

Well i hope this story wasnt super long, but i was just a little disappointed, because even if i messed up like that i should have atleast been pulling on him, but he was pulling on me more and more.

My car is all stock with me and my friend in it prob about 3850lbs give or take a few his car 270-280hp FWD around 3070 with driver

any suggestions? things you would check? Diagnostic? Dyno tune?

PS please dont recommend upgrades since i just bought the car and ill need some time to save up a little :rolleyes:


My soup, took pic at work today. stock 95 TT 6 speed 113k

First of all nice supra ive always dreampt of buying one. Ne way can u plz send me the vid ([email protected]) id really like to watch it and i dont think you can hear the stock bov on a stock supra cause i have been driven in many and have never heard it.
Sorry but i cant giv ne technical suport because im only 15 and dont know thats much bout tech things i know a lil but not that much to give advice.
I would really really apreciate if u send me that vid.
Thnx

you got it, sending it to you.

I reved the car up only to about 2k and then dropped the clutch and the car bogged really bad and he got me from that and then i had no chance because he was already pulling on me because he was at full boost and i wasnt even at the spooling level haha, i had all the lag in the world...

I did practise launching tho now, that was only my second time driving my supra since i bought it last saturday. I now launch at abour 4k with no probs and my friend and i did a street 1/4 by this school and i got 14.4 both times, so i got better now. I did 1/4 on that same street with my 240sx and i got 16.6 there and the actual 1/4 track i got 16.2 because the distance i meassured is prob a little off so that street where i did it is pretty much whatever time i get and minus .4 and plus i had my friend in my car when i did the 1/4 on that street and its uphill at the start... so im looking at about 13.8 at the track...

ill be going to the track wednesday (5/25) so wish me luck!!

You can hear the stock BOV but you have to listen very carefully. My car when it was bone stock long ago dyno'ed at 280whp. If you friend is doing the same thing it would have come down to the start. Eclipses weigh close to the same as a MKIV so there's no advantage there, he running higher boost where as your running about 12. So if you look at the race the start is where it would count for your race with your friend.
Chances of the BOV being bad would mean ethier three things, one your car will not build boost because it would be open all the time. Two you would have blown turbos because it would be shut most likely. Or three, you have a leak in your vacum system. Re-check your vacum lines to make sure you don't have a leak, which is most likely the problem. The first things you want to do to your car when you've made sure that your car is fine is buy an intake, exhaust, downpipe, fuel cut denenser and a boost controller. A front mount intercooler would not be a bad idea but a good one from a company will cost around $1100 with hard pipes. You should be running around 18 psi with no boost controller which is safe, but before it starts to get colder outside, you might want to get a boost controller in the future. Being colder air, your turbos will force feed more air which will up your boost. I wouldn't recomend running any higher than 19 psi on premium gas and if you had higher octane gas such as 110, 116, or higher you should run about 21 psi just to be safe. After those mods, you should be easily walking that eclipse in not time.

got a major boost leak... ALSO this is why i think my BOV was not releasing pressure...

i turned on the massive aircompressor and got about 15 psi pushing out of it, because i didnt want to blow any seals and trying to play safe... and at ONLY at 15 it was leaking.... and right where i suspected... by the BOV where those 2 hoses connect to the BOV... That also explains why there was some oil there on the BOV and on the pipes in that area because it was pushing all the oil out from there.

I turned up to about 25psi and it was blowing even more... So, major boost leak. Im gonna go to autozone and see if they got some hoses so i can replace mine

Also the BOV are really hard not cracked yet, but just hard and dont bend at all... so the clams were not clamping them down hard enough. possibly if i bend them they will crack in half...


Pressure test picture haha... that foot pump thing wasnt a good idea because the engine needs more air forced in there, so i used the actualy air compressor and shot some boost in there at 30psi after i fixed the hoses and it wasnt leaking anywhere

heheh! $40,000 and its yours!!

nice car, did you switch to chrome rims later? Cause in your sig you have chrome and in your first post the rims are dull

nice car, did you switch to chrome rims later? Cause in your sig you have chrome and in your first post the rims are dull

no its just a different supra in my sig, i had that sig for some time way before i bought my supra.

im thinking about going chrome or polishing, we will see, i got a few other things to worry about at this moment. like me 14.9 1/4 time with a spped of only 95mph :disappoin

thats my next step is to figure out whats going on and get into the 13s before i go BPU

Hey i just watched that clip, damn you got off on a bad start if you had of got a better start it would of been alot closer but even when you were at high revs he was still gaining so i dont know if you could of had him.
Nice clean engine bay aswell.

heheh! $40,000 and its yours!!


on second thought, you hold on to it for a while! lol

send me the vid real quick and ill let u no wat i think if u want [email protected]

hooked up the greddy boost gauge tonight and ren the car and pushed it to the max... here are pictures of the boost gauge at idle... and at full boost

the full boost goes up to only 0.5 bar wich is 7psi... also i was watching the boost gauge and i could see the boost drop when the 2nd turbo kicks in... and then it goes back to 0.5 again... so its not going over 7psi and the boost stays at that boost... it does not drop at all till redline when i let off.

Is that 7psi for your stock supra??? Is that how much supras run stock???

no stock psi on a supra is 11-12 mine is at 7psi right now and i just did the TTC mod that was hopefully gonna fix the problem, but now im running at 4psi max... im thinking my second turbo might be bad, or the wastegate is just all messed up or who knows, but ill be trying to find answers soon, as i really do need to beat 14.9 at the track and gain the supras repetation haha :wink:

all i know is if i got 14.9 with 7psi... at 12psi how it should be, ill prob be in mid 13s with no prob!! and for that... i cant wait!!!

well i hope you do run 13s and i hope when every things better and your on 12psi you smoke zach not he smokes you. good luck wit your car.

thanks man :) im working on it.

I have now found the sourse of my problem, after all this time!! No wonder it was so hard to figure this out... the butterfly flap in the EGCV where the bottom actuator is supposed to open (the one that you wire open when doing TTC mod) it broke off... not the whole thing, but just the lever part connected to the actuator.

So thats why when i did the TTC mod my car was only pushing 3 psi max at any given RPM or gear. After i did TTC and it didnt help, then i went back to sequential mode and it made it worse than when it was before the TTC mod. So then i decided to try and do the TTC mod and be sure i do everything right. When i went to the the bottomr actuator, i disconnected the C clip that is holding the lever to the rode and i played around with the lever and it just pulled out like nothing was holding it inside!! so im all crap.. no way!! my butterfly was broken and it could be close or fully open when ever it feels like it haha. SO...I pulled my exhaust and DP off and then i got into the EGCV pipe and i broke off that butterfly flap completely, now i have 2 holes on the sides of the EGCV pipe. So i closed those up with some exhaust gasketmaker stuff lol.. i knew it wasnt gonna hold, but i did it just for the heck of it.

So with no butterfly in the EGCV pipe i had to ofcourse wire open the top actuator so im not at permanent TTC , wich is nice, because i dont have to worry about blowing up the #2 turbo.

So after i got everything done and put the car back on the ground i decided to go for a little drive around town and see what boost i get this time.

I was etting 9psi max easy and it holds it all the way to redline with no problem as well. After a few hard pulls, one of those side plugs on the EGCV pipe finally gave out and now i hear and exhaust leak, wich is not a problem because ill get that taken care of when ill be doing the downpipe and the exhaust in about 1-2 weeks or so.

I just today did the wastegate spring mod, wich will keep the wastegate VSV closed for a little longer and letting me boost a little higher, and hopefully at stock levels of 11-12. Once i get my 11-12 stock psi back then ill be a happy camper and ill take it to the track next wednesday and try to get into the 13s!! :naughty:

Ill also try to relocate my boost vacume line to different locations to see if the boost will varry from spot to spot. Some people say it does. Mine is connected to the intake manifold nipple almost right next to the throttle body, so the boost might be slighty less there, and i might be at 11-12psi max like i should be on a stock supra just my gauge is a little off in different locations. People say hooking them up to BOV vacume line is the best sourse. So we will see. If i hit boost cut with my spring mod then im sure over stock psi. boost cut hits at like 13 i believe.

here are some pictures of the EGCV pipe i was talking about, and the butterfly flap inside that i had to smash out, and also you can see the holes that i glued up there... also you will see a few pictures of the wastegate mod,... so if you ever plan on doing neither, hope these help you. (first pic is the braket piece that holds on to the buterfly flap.. you see it was broken off. i have no idea how, buw i heard a few people with this prob)

i disnt understand much of that but im learning at the end of this year im going to leave school become a mechanic and i will start learning alot more and cant wait until i become a mechanic. so your on the way to fixing the problems hopefully wont be long until your supra is running 11-12psi and doing 13s down the quater mile. Just out of curiosity im going to be looking for a car soon and i was just wondering if you were to sell your supra how much would it be for??
And would you advise for me to buy a sup or a 240 ive always had them 2 in my mind since i was 10 lol.

well if you ever want to talk about what you didnt understand, i can clear it up for you, im always on AIM at GT500916

As for ever selling my supra and how much, well, if i was gonna sell it right now, i would not let it go for less than $25k its low miles and 5 speed and i changed all the tranny and LSD oils and chcked everything and according to my knowledge this car has been mentained through its whole life. Oil was always changed in the engine every 3-5k miles, no smoke at all indicates this car was taken care of and the turbos dont smoke or eat oil, meaning it was not pushed to its stock limit. Also the clutch is still original meaning again, it wasnt pushed to its max, also treanny fluid is clear and redish, like new... so again, all the signs point to my conclusion that i got really luck with this car, since it was a one owner who mentained it through the dealer all the time, cuz he knew nothing about supras therefore all the work had to be done by the dealers, or other shops.

Supras value is going up and i doubt it will stop going up. Now about the 240, those are great cars as well... but i preffer the supra because its awesome!! and i was gonna turbo my 240 but here in CA regulations suck, so thats why i had to get a stock turbo car so i dont have to worry about that. I dont know what state you live in, so i dont know what your state will allow as far as moding a car. But if you have no regulations and want a fast fun car, id go with the 240sx and put a turbo on a stock KA motor, The engine can safely hold 400hp and the crank on the stock KA engines holds up 600hp with no prob. Depends how much HP you want. With stock 240 engine you will get 400 and its lighter, so would be more controllable than a supra, but supras potential is 900hp+ on a stock engine... so you do the math and its what you want. cheaper yes... but you get a 240sx for say whatever price and get turbos and parts and all the work on and on... and you might even spend as much as a stock supra.. its all about what you want. i have both, and my stock 240 doesnt compare at alll!!!

I live in aus and 25k in us dollars is about 40-45k over here thats a fair bit for a stock but well maintained supra, over here you can buy a 600hp+ supra for around 35k au dollars. i think i would get a supra if i had the cash but i dont know if your familar with it but a 180sx is what im looking for its similar to yours but looks different and is cheaper than your model.
