95 3000gt help ... please..

[lockylocke]

hi ... I really need helps from 3000gt experts. I have a 95 3000gt base. 2 months ago in a cold winter night..after pour in 1 can of Outlaw Booster....for a few hours....the car just suddenly went "boom" in the engine, and seemed to runs only 4, 5 cylinders (lost hp dramatically). Plus the muffler make "boom..boom" noises ..like having bad fuel problem or a hole in the muffler.... I took to a shop.. they replaced the coil ignition package, and told me that ... the engine problem is solved ..and it seems to me that the car gains some hps. (still not as fast as it used to be)...However.. the "boom ..boom" noise in the muffer still there and..he told me that there is a hole in the muffler....I took the the muffler shop... but they told me they can't find the hole, and that there might me one but it's up to me ..to replace the $500 muffler, and he cannot guarantee that the boom ..boom noise will be gone....Now i am driving in that condition for 2 months with engine vibrate hard sometime. It's really pissed me off ...'cause the original 222 hp ..now it seems to have only 140 hps... and the noise will not go away...

Please help if you have any idea of this problem. Is it 'cause the muffler only.....After I replace the muffler will it go back to the original state??? .. My previous toyata camry had bad muffler.. after replacing it ..the car did gain some hps..but i am not sure if that is the problem this time...

I plan on selling it..if I can not fix the car...
Thanks in advance...

base model only has 167 HP i believe... 222hp is the SL model.......And about the car... how can mechanics NOT find the problem? IDIOTS...

The 95 base models had 222hp, they still had DOHC. It's the 97's and I think 98's that have SOHC. As far as the problem goes, I would sell the car and get another 3kgt in better condition that won't give you so much of a headache.

Thanks Seraphin for the advise. I'll try to find a better mechanic to fix it.

'as for GTO, better do research before posting your reply. I wouldn't bother to ask this question if i know the problems through mechanics who i took the car to

I'm looing at getting a 94-99 VR-4 ok.I just wanted to know if i was racing a stock GSX with me stock VR-4...what one would win.The VR-4 right?I mean having 100 more hp would do it wouldn't it?

Stock vs stock, VR4 wins.

Everything about the VR4 is better than Gsx ... except the insurance and cost to maintain it...haha

NO GTO4LIFE is right, the base car was not supercharged the sl was,though the sl is still no mach for a vr4 or supra
