firebird vs eclipse

[TatII]

yup. the first gens came with 16g's i believe and the second gen's comes with 14g's. so the first gens are lighter and has a larger turbo. there is this guy that i talked to, he has a first gen talon tsi. when he was still runnin his stock turbo on 15 psi with a full catback and a intake, he ran a 13.1 impressive.

Let me be so kind as to correct you. And throw some of my DSM knowledge out there.
The 1st gens , 89-94 , came with a 14B turbo stock. The 89-92's had the 6-bolt motor , the rest have the 7-bolt motor , the crankwalker.
The 2nd gens , 95-99 , came with the T-25 turbo , a Garret unit , used primarily for its low rpm spool-up qualities.
The heads are no different between the gens , only the intake and some changes to the block , higher compression pistons in the 2G only 7-bolt motor , and smaller rods in the 94-up 7-bolt motor.
The 2nd gens have a bigger MAF , which is sought after by the 1G crowd as an upgrade to their pitifully small stock MAF.
The 94-up cars came with the bigger brakes , also sought after by the pre 94 modders.
To get a truely awesome car , you have to mix and match parts from both gens.

yup that was exactly what he told me now, i remember. i just wasn't sure. yeah he said that the first gen came with a 14B turbo and he upgraded it to a 16G now. also he told me that his car was hesitating on the high revs on high boost because he maxed out what the stock MAF can read out. ahhhh yes. alrighty then. thanks for the info. by the way i always thought that the first gens all came with that turbo. and that only the 2gens had the motor with the crank walkin problems. i guess not.

Oh it must have been the rods was the reason you can boost a 1G more, also because of the larger turbo. Thanx for the info ROCKINWRX.

I did forget to mention that the 1G automatic cars , 91-94 , came with a weird little turbo called the 13G , and cams profiled for more low-end torque. Bigger than a T-25 but smaller than a 14B , the 13G turbo was installed in the A/T cars to help overcome the slow acceleration they naturally have. The 13G is considered an "upgrade" by the 3000GT-VR4 guys , as those cars come with a pair of T-25's stock.
The 2G A/T cars have the same T-25 as the M/T cars.

And yes , the 7-bolt 1G 1994 motors are subject to crankwalk as well , although not as infamous as the 2G cars.
To build the perfect DSM would require an early 1992 year car , which was the first year for the stationary(non-pop-up)headlights , taking about 40lbs off the front of the car , and the 4 bolt LSD rear axle , which is prefered by the racers. The big brakes and 7-bolt engine came in 1993(the engine in late 92) , and the 2G body style , with the bigger MAF , in 1995.

Heres a rundown of what happened between 92 - 93

1992

Non-popup headlights introduced on all models.
The first AWD Lasers were introduced.
Few (or no) ECUs have EPROMs.
ABS now available with LSD.
The engine changes from the 6-bolt version to the 7-bolt version in April.
Second and final year of the Galant VR-4 - 1000 sold in the American market.
The last year of the Dodge 2000GTX.

1993

"Big brake" 2-piston front calipers become standard on turbo models.
7-bolt engines are now standard.
No ECUs have EPROMs.
Diamond-Star Motors ceases to exist

Heres what happened 94 - 95

1994

All cars built to California emissions standards - there are no "Federal" cars.
The last year of the 1G car and the 1.8L NT models.
The last year of the Plymouth Laser.

1995

The inagural year of the 2G DSM.
Significant changes to the engine, body, and electronics.
New transmissions.
All ECUs have EPROMs.
Non-turbo models are based on the Chrysler 420A engine instead of the Mitsubishi 4G63 engine.
OBD-II becomes standard on DSMs, along with two oxygen sensors.
Mitsubishi begins using some substandard crankshafts, leading to crank walk on some 2G cars.

Thanks again for the info.
