Thread: Best mods for a stock SSEI Bonnie.

Hi, resident Bonneville Owner here.

with the 97's i would recommend what you have told him, except the TB gasket, you can pull the charger off with the TB attached, they rarely go bad.

i would get a PCM, or a local that can Tune the car, and the rockers. You wont gain anything out of the rockers with out the raised shifts. Remember you will need to get springs with the rockers.

also some free mods you can do is smooth out the outlet of the charger, and the Lower Intake when its off the car

ya you could clean it, but its just gonna get gunked up again, thanks to the EGR.

The Airflow that the car is seeing, will be off, because of the rockers. Personally i dont think the car will run to its full potential with it being untuned with the rockers.

I would try to find someone local to tune it, and then do rockers at the stock shift points

rockers arent really going to be all that beneficial on stock manifolds. id look into some form of exhaust work first, whether it be a downpipe and a plog or a set of headers.

How about...

Power Log $119.99

ZZP downpipe for Bonneville
Size: 2.5" full length weld in
Model:Aluminized
Option 1:Magnaflow cat
Option 2:Add o2 bung in offroad pipe $184.99

Valve cover gaskets $27.99

RTV Ultra Copper $5.99

Intake gasket $54.99

Supercharger gaskets $8.99

Throttle body heat shield $29.99

NGK Spark Plugs
Model:TR55 $14.00

ZZP supercharger oil $10.00

Total $456.93 + 27.74SH = $484.67

Plus about 65 bucks for coolant, oil, thermostat from auto zone.

Grand total: About $550

A couple of questions about this... Is the TB shield worth it? Also, the down pipe page says it is a weld or clamp style. Is it ok to clamp these? If it has to be welded we'll need to cut money somewhere. One last thing, what exhaust bolts, gaskets, etc are needed?

i would go with autolite sparkplugs. 605's. also no need in getting the back manifold ported, its not going to help much. your going in the right direction with a powerlog and downpipe. your also going in the right direction by taking care of the gaskets and trying to get some maintence out of the way.

its a good start. your going to need some exhaust mods to drop pullies later on. if he does not have an intake yet, make yalls own. theres write ups on how to do that around here.

i think it was 10 bucks for 6 the other day when i got some.

i dont think a tb shield is really worth it. i dont know how much it is but im sure you could make something for way cheaper. you could also wrap the crossover and that would cut down on a lot of heat.

as long as you get some good clamps and coat it with rtv there is nothing wrong with clamping it. and i used the stock bolts and gaskets that were on the car for the exhaust. there metal so there resuable. if you break a bolt, which might happen because that is notarious for the crossover, then just pick one up at the local hardware store that will work or find one thats laying around the garage or something.

any exhaust wrap will work. you can pick it up at autozone or some where like that. as for the clamp, just a good band clamp with some width to it, like 2 in. wide so you can get a good clamp on it. band clamps have bolts on both sides that you can tighten down. with a wide one you make sure its not to short and you can get a good clamp on it. check out your local parts store for one. usally a couple of bucks.

nothing crazy, a little more umph. but its a start in the direction of droping pullies later. atleast you will have the exhaust taken care of.

but going from stock to that, you will be able to tell a difference.

If he wants huge differences buy a Honda and turbo it

I'd say plugs/t-stat/CAI of some sort...make your own

Then a DP with a U-Bend delete with it...should be around 275 bucks...
