Avenger Turbo?

[3.0ShadowES]

Anyone know how much boost the stock 420As could handle? i have a rebuilt TE04H im not using.

I would guess mid to high 200's HP

ur wasting ur time, avengers are trash .. i had a 96 and a 97 the 97 420a didn't handle boost worth crap i ran a 14b..sry

stock they can probly handle about as much as ur lungs can spool a turbo

Kinda figured, so should i waste the money in forged parts, or drop in my 273 from my dart? Kinda obvious

same motor as in a neon, Ive heard of stock cranks taking 365 (not sure if crank or at the wheels but still more than listing above) as well as guys using T2 rods in them, and what head do you suppose TD'r use for 16v conversions, the 420a head, keep the 273 in the dart

[amiturbo]

Yea the heads are awesome but the lower end on mine didn't respond to boost very well at all. New oil pump and the bitch still spun a bearing.

I thought the 420A Heads were crap, i dont know what i was reading. BTW the 273 was in a d/dart my brother wrecked back in 81, well anyway, i might just go on with the turbo plan, i have a backup motor in my talon.

On a stocker 8# is the limit as far as neon motors, the 420a is similar. If your running 14# without pulling some timing then too much boost and detonation killed your engine

So i'd be safe running like 8 psi with a stock bottom end or should i take the time and money and do a forged bottom end,pistons and rods, the crank would be more than the car is worth.

i was running stock boost from a 14b turbo not 14psi

I pulled the motor and im gonna rebuild it from the ground up with forged rods and pistons but stock crank. Ill prolly start rebuilding it in the beginning of jan so ill keep you guys up to date.

You should also check out Hahn Racecraft's site.

The 420a is one of their specialties....even in the 2gNT/Sebring/Avengers.
