pick up a haynes maunual and test the injectors and whatever you suspect is not working properly. Do a search for how to fix the vaccume leak. I dont quite remember how, and with the rest of the money it might be a good Idea to get a FCD and silicone hose kit and try to replace injectors, or get them survised. you can pick up an intake for pretty cheap too. Will the car start? Try to get her running b4 modding it up too much.

PS you name reminded me of a riced out neon with a huge sticker on the back that said NEON it looked real fast. LOL

You can replace all the vac. lines yourself. I did mine last summer...not a big deal and not expensive. I just used regular rubber vac. lines. The leak should not be hard to find. To test the injectors just check for pressure leak down at the filter (to confirm the fuel pump does not "leak down" and then at then through the whole system with the outlet at the FPR blocked. If the FP checks out OK and you get a pressure drop then the injectors are leaking.

for now, keep your emissions stuff on there. dont try to get rid of the EGR or any of the stuff thats PART of the engine. we can try to figure that out later.

for now, u can get rid of ur Air pump and knock out ur cats. that air pump sucks a few HP. if its not there, ur engine doesnt have to waste power trying to turn it. BUT if u take that off, you NEED to gut ur cats, or put on a straight pipe. the Air pump puts air into ur cats, if u take that off w/o gutting ur cat, it will over heat, and melt down, and clog ur exhaust. not good.

id say, tear ur intake off, and replace the vaccuum lines under there, and reseal it all. theres alot of vaccum crap under tehre, and they are preformed hoses so that they will all fit in there nicley. if u just use hose from a reel, it might turn out to look like a RAts nest under there, and that would be a pain in the ***. just see about getting OEM replacement parts, www.mazdatrix.com should have it. or call ur dealer, and order parts from them.

honestly, the dealer is more expensive than Mazdatrix, yet they are the same parts. Trix parts are like 10-20% cheaper than dealer parts. but they come from the SAME WAREHOUSE, out in irving, california. no lie.

anywho, check all vaccum lines. make sure all ur sensors are plugged in, liek ur MAF sensor mounted to ur air filter box. i think tahts all i can think of for now. try to leave **** on ur car so that it will at least run, we will focus on strippin it later. if u need anythign else, let me know, PM me, email me, or post something on here.

chris

PS; i dont have a liscense, no road trips for me...apparantly theres something wrong w/ going 132 down the I-70..*shrugs*

to find small vaccum leaks, crank up the car, get a can of throttle body cleaner and spray where a vaccum leak might be. if the idle rises then there is a leak.

Drift; i think one of his problems is, that he cant get it started in the first place, i thot of that spray can trick before...but didnt say anythign cuz i thot he couldnt get it running.

Jay, order the parts you need from Trix, they would probably take about 3 days to get to you. they are all genuine mazda parts, so theres no prob about them fitting right. i would DEFINITLY get the injectors inspected, tested, and blue printed, itll save you the trubble later on down the road. if u dont, a leaky injector may show up a few hundred miles down the road...and youll be stuck off campus w/ a flooded engine, and i wont be able to give a ride, cuz i have 14 points on my liscense! its a cheap insurance step to keep ur engine running good.

im gonna hafta get mine done if i dont sell the car. cuz sometimes, if ur injectors arent holding pressure, they will bleed off fuel into ur intake,and down into ur engine, causing it to flood. the prob w/ our cars, is that u cant just let it sit and have the fuel evaporate...its can be a long procedure to unflood ur engine, especially if it sits for a while in that condition. belive me, i KNOW!!! its a long story, and a pain in the *** too.

and the engine SHOULD still have compression, i doubt its gonna go bad in 75 miles. if it DOESNT, it means that ur injectors already flooded the engine. if u go to start ur engine, and it just spins like theres no compression, and no puffs in the exhuast...chances are its flooded. if thats so, just let me know, ill tell u what to do, step by step. or someone else on here can help too.

if it sounds like "RRrrrrrrrrrrrrrrrrrrrrrrrr" that probably means theres no compression

if it sounds like "RRrrRRrrRRrrRRrrRRrrRRrr" it means theres more than likely SOME Kinda compression in it. you should also hear some puffs in the exhaust too.

anywho, let me know whats up.

chris

PS: ive never gotted PULLED over for fracturing a law like that. just for piddly stuff, reckless op, failure to stay on marked pathways (long story), speed (x4), "squeal and peel", assure clear distance ahead (Ran into a offduty cop)...but NOT for triple digit speeds. hehe

Edit: about the exhaust bolts. do u mean to remove the exhaust from the manifold??? or to remove the manifold from the engine? exhaust from the manifold is easy, just 2 nuts. just jack the car up on the passenger side, behind the front wheel. u can even use the jack thats in the car. the manifold...well i don tknow, never had to take it off yet. but, it should be relatively easy, just the heat sheilds might be in the way.

I don't know who told you that, but the engine actually makes more compression when it's cold...

Whoa!&nbsp Don't get bent out of shape yet!

Depending on what kinda compession tester, 85 all around should be a good number...

Jay, ur compression should be ok. i mean, you gota keep in mind, Turbo cars have lower compression ratios than an NA car. cuz the turbo packs the air into the engine, and raises the compression ratio that way.

but, 85 does seem low. i mean...if u take 85psi/14.7psi=5.78:1???
is that right? compression psi divided by atmoshperic psi= the compresion ratio?

anyways, in toledo, thers a cruis-in car show at WEstgate shopping plaza every thurs night thru september i belive. my buddy organized it last year, and i always had my trans am in it. always had a group of people checkin her out too. hehe. i think the car crowd isnt very organized in toledo, as far as i know. if anything, we can go hang out at Defcon cuz thats sort of like a clubhouse or treehouse for us OLDER kids. ill just need a ride there, lol...i wont get my liscense back till Dec 19.

anywho, as far as ur exhaust, put ur car up on jack stands, and take the pipe off from the manifold, or from the tturbo anyways. leave ur turbo assembly on ur engine, itll save u the trubble. u wont have to worry about maneuvering that heavy *** chunk of iron around.

anyways, have fun w/ it.

well if the engines got lots of gas in it your numbers will be smaller. did you do the test with the pedal to the floor? is your battery in strong condition? if not you'll get lower #'s. I'd get it started and running then try again. it'll run with 85.

According to the Haynes manual, 85psi is the absolute minimum to have for a good motor. Since it is showing 85psi, you're motor is good. There are several factors that contribute to compression though. Dirty oil? Seals could be bad? Carbon build-up? etc.. You can get away with using the Transmission fluid treatment that will raise it at least 10psi on both rotors..

Don't feel too bad. When I got my engine checked, it read 105psi - front and 92psi - rear. And this was with dirty oil (and low oil to the point where the light came on). I'm sure it's probably a little higher than that now. But I'd say an emmaculate engine would put out 125psi/front and 115psi/rear..

Jay-dawg

i think you should be ok to take the air pump off now. since u dont have the cats, you dont have to pump Air to them. im not sure if the air pump is used to open any ports like it does on the 89-92 NA cars...but urs is a 4-port turbo motor, so i dont think ur air pump runs any ports. Yank it.

if there are any stray hoses that used to connect to the cats, u can take them off. like the line that injected air into the cat. and the hose that ran from the air pump to anything else. if you end up w/ an open nipple or connector where an air pump hose used to go...just plug it up some how. you could leave a short section of the rubber hose on the nipple, and plug it up w/ something.

one time what i did, was take the hose, bend it back over it self, like how u kink a garden hose so that the sprinkler turns off. and then i took a screw-style hose clamp, and slid it over the kink and wrenched it down so the kink seals off the end of the hose. might look cheap, but gets the job done. lol

i can help you install ur Haltech, ive never DONE it before, cuz i have an NA car. all u need is a good wiring diagram so that u can splice into the correct wires tho. i bet its gonna be a bitch to tune. the shop in toledo would probably be able to help us out. most of the cars i see in there, arent as serious as this, most of them are equiavalent to ricey hondas. they have nice piggy back computers like SAFC's, and VPC's, and **** like that. not a whole stand alone engine managment system like a haltech E6K. anywho, just keep calling RC eng. and nag them. it works. theyll get on the ball. trust me.

hell, at work, we gave a girl a job cuz she simply NAGGED us so much. she wasnt qualified any better than ur average joe, she just BUGGED The hell out of us, so we hired her. anyways, good luck bro

chris

PS, Jay-bone, send me an email or something i can hook u up w/ my pager # and u can get ahold of me when u come to town. oh yea, last week i did see a mustang gt at the cruise-in. i think it was white. it had the exhaust pipes coming thru the rear apron. is that ur buddys car? it wasnt bad lookin.
