questions about making a fast N/A SHO

[94BCSHO]

I've got 2 questions for when modify my car in the far off future (broke right now between tuition(sp?),car,insurance,gas)
Note to self need student lone

anway i would like know how big of displacment i could make my 3.2 and using that displacment and totally redoing the engine performance wise without using boost or nitrous( i would like to see would like to keep NA, i mean boost is great and all but i think its more amazing when you can get alot of power out of just the motor and nitrous is for people who cant build motors). Anyway getting back on track what type of hp and lb ft figures am I looking at out of a large displacment built NA SHO

 

[FastAndFurious]

I would say about 300whp.

You think your broke now..... A N/A build is going to be very expensive. Boost is easier, and these cars LOVE boost... I would like to follow a N/A build myself, but i think ill boost it at some point... Even if you do decide to boost way later down the road, you'll be happy with any motor work you do IMHO..

You might see 275 whp and 250 wtq, but to be honest you probably won't see much more then that, especially if you run a quaife. I am talking on a fully built engine, as in there is no way to get more hp out of the sho engine n/a w/o a lot of work and money. I'm a N/A man myself, and I can say it definitly costs more to build a n/a engine on these cars then just boosting a stock engine.

Oh and you can bore to 93mm, and use the 3.2L head gaskets, any further and you need custom head gaskets. I have been told about a 94-95 mm bore is possible so long as your specific block walls are thick enough (that means you need a 93-95 block 3.0L or 3.2) and you need to get it checked for wall thickness before boring that far or you will have overheating problems. You can also stroke the engine to 3.6L but that takes a LOT of money, But if you do decided to offset grind the crank make sure you get it re-hardened or it'll snap in no time.

Around 300whp.

But your going to spend twice as you would if you just did a turbo setup or supercharger.

 

[SuperHO]

just ask ernie how much he has in his n/a setup and how much power he's makin...a turbo setup'll yield you more power, be more streetable, and a helluva lot cheaper...

All it takes is time and money. Something a person in your position does not have.

If you HAD a bottomless wallet, the sky is the limit, but were talking $10,000+

Custom everything...the only thing left "stockish" would be the heads and block.

Custom crank
Custom pistons
Custom oiling
Custom computer
I could keep going on and on.

Since the sky is the limit, what you need to do is figure out how much power you want to make and then figure out how.

It would have to be a very high compression engine with a powerband in the 10,000RPM range.

Even then, you would be able to get more streetable power from MILD boost.

The key phrase here is "there's no replacement for displacement". With boost, you are effectively cranking up the displacement without changing the internals of the engine.

If you REALLY want a N/A powerhouse that's somewhat affordable, plan on maxing out as about 250-275 crank horsepower.

Im with them , my N/A build cost alot , and I dont even have the hi-comp pistons. I got something near 10K$ in cosmetic and N/A mods , I think the only N/A mod left to do for me is the pistons.

Plus to save some money you will need to have some tools around /welder /garage and so forth.

I have yet to put mine on the dyno but my guess is around 260-280whp which is around 290-310 crank hp.

If you do this , that vehicule needs to be a toy , not a DD. If your SHO is a DD AND a toy , go turbo.

Most of my mods are in my signature.

That would be more like 305hp - 330hp and don't be surprised if you're not even close to that.

I was honestly thinking that but didnt' want to be the first to say it. I was thinking like 220whp maybe...

My car makes 220 FWHP and it's just a 3.0 With Cams, EH Intake, BBB's with a Ypipe, mated t a single exhaust without a Tune. His Built 3.2 should be making AT LEAST 10 more FWHP then that.

Area make 257whp with about same mods as I.

 

[yamahaSHO]

I know... However, it is a long shot. Dyno it.

I've found the best thing to do is to go in expecting lower numbers. It sucks to be disappointed... BTDT.

 

[1995SHO9]

Area91 make 257whp with about same mods as I.

Who is this "area91" you speak of?

Yes, please just dyno it, its only like 80 bucks and then we can all stop arguing over the power it will make.

Seriously?

 

[94BCSHO]

that 300 to the flywheel is that at stock displacment and if so how much HP will I get with it stroked 3.6L and then have it bored to 94-95mm (cars a 94 ATX) what type of power am I looking at

 

[93rev2sev]

you won't stroke it to 3.6. That's what were telling you...in a nicer way.

I think there have been a handful (read "less than 5") successful 3.6L sho engines built in the 20 years SHO engines have been around. As far as I know...there is ONE... that hasn't grenaded the crank...and he's spun the bearings more than once...

This engine is what they call an "over-square" design. Your research should start with what that means.

Trust the people that have been there. They have made the mistakes so that you don't have to. If you want big horsepower, boost it. Period.

 

[hawkeye18]

The SHO engine is definitely oversquare. The 3.0 is 89/80, which equals a ratio of 1.1125. The 3.2 is more oversquare than that, at 1.15. Most, if not all engines nowadays are oversquare, as it has so many more positive traits than an undersquare engine. The old Chrysler slant 6s were the last popular engine to be undersquare that I know of...

If you turn the SHO into a 3.6, the bore/stroke would be 93x88, which gives you 3.585L. That's a ratio of 1.05. Still oversquare, but just barely...

Jason you da MAN!

I've got 2 questions for when modify my car in the far off future (broke right now between tuition(sp?),car,insurance,gas)
Note to self need student lone

anway i would like know how big of displacment i could make my 3.2 and using that displacment and totally redoing the engine performance wise without using boost or nitrous( i would like to see would like to keep NA, i mean boost is great and all but i think its more amazing when you can get alot of power out of just the motor and nitrous is for people who cant build motors). Anyway getting back on track what type of hp and lb ft figures am I looking at out of a large displacment built NA SHO

I'd focus on school.
