So I have searched with various yet minimal results but not with what I am after. Can anyone give me a better understanding of the ballpark cost and hp that can be expected from full bolts (intake, intake manifold,heads, cams, header, tune)? Mind this would be a street car running E85.
Thanks.

when you say full bolt ons, then say things like heads and cam, your question is confusing, since you are saying both integral bolt ons and external bolt ons. You can Bolt up 1000 Hp, you can spend 25 grand to do so.

What most people call bolt ons do not include internal components.. You can get 100 hp with bolt ons, add juice and you can get 200 hp.. cost for typical bolts on can range about 2 to 10 grand.
A 1000 HP clutch can cost 3800 dollars.

What ET said... everything in theory is a bolt (in/)on. Bolt ons are generally items that go on, or outside of the block and heads.
A cam (singular) is internal.
Heads are part of the long block.
Further, if internals are part of your plan, what level of cam, heads? 243 stock heads, ported, aftermarket? Mild street cam, wicked cam?
Do you have a goal?

Head on over the the Classified section and start price searching. You can get some great deals.

I suppose my question stems from wanting to know how feasible it is to 400whp - 450whp from a C5 base? Also what what will it cost to get there?

Evil-Twin

you can do it with juice for about 500 dollars but that is only when the Noz is engaged. You can get a supercharger and get there for 6K plus install. But other items should be added, another 2 grand. You can get close with Headers, intake and a tune 2500.3000 ( close to 400 rwhp )

Andrew

Generally agree ET, but do not expect close to 400 rwhp on a base LS1 with headers, intake and tune. Getting 400 rwhp with those on a z may not be possible either, unless you are on a happy dyno.

Chris Draper

With heads, cam, intake manifold, cold air or ram air intake, headers, exhaust and tune, you can expect around 420rwhp from a stock bottom end LS1.

Cost varies on what parts you buy and who you have do the work.,

I think this is an accurate, but quite conservative statement. On a tight budget, yes, 420rwhp is probably close. But with almost any LT headers, LS6 intake, 243 heads, cam, and tune; you can land anywhere from 420-450+rwhp depending on how big of a cam you go with and if you have any porting work done on the heads.

Youll want to add the cost of a clutch onto that, at a minimum.

With saltier heads (PRC/TFS/AFR) and a well matched cam, plenty of guys get closer to 475rwhp. But that’s typically a no nonesense build that can be quite pricey by the time you factor in driveline upgrades and other supporting mods

For a frame of reference, I’m in the middle of an N/A 450+rwhp build. Without cutting any corners and “overbuilding” the driveline, I’ll be in it for 8k+ by the time I’m done. That’s with me doing all the installation myself. I’m pretty sure that’s where I’m at...I’ve lost track of the total numbers by now

This is a lazy man's question. Go to any performance parts company and view the prices of parts. Labor .. do it yourself or pay someone a $100 per hour.
Or use your i phone and call a shop they have answers.
Do a little research.
Good luck.

All in mine cost me about 7gs to do a full heads cam setup, netted me 456/420 on a dyno jet, 2004 base. Obvious a chunk of this is labor as I don't have access to a shop anymore, paying for labor was painful...but I know it was done by professionals.

Blackwing intake(DIY installed 2 years ago)
Lg Long tubes( DIY installed 2 years ago)
Fast 92/LS2 TB(you could go ls6 mani to save cash unless you already have one)
Advance Induction HCR 241 program heads with BTR springs/rods/caddy lifters/CHE Trunnion upgrade(DIY install)
Lunati custom spec CSP cam 223/235 113+2
55# FIC injectors

Another thing to consider, my clutch at 50K did not like the power, 2 shifts and I was done, stuck to the floor...I ended up doing a Monster lt1-s clutch and had 3.90s and the trans rebuilt, another 7K.

Part of me wishes I would have saved the 14k and invested in a newer car, but I own the c5 and it doesn't owe me a dime, so I decided it was worth the money.

The car is a lot of fun on the street, and I feel it will be dead nuts reliable with this power level and parts.

e85 may not be worth doing on your setup... the gains will be minimal and it will only add to the cost if you have to get bigger injectors/pump/flex sensor/etc plus the cost of rewiring the pcm and tuning the car to run flex or you can just get it tuned to run e85 only but for maybe 5-10hp that may not be worth the hassle in my opinion

Andrew

Some good info posted. It is more expensive to get power without a power adder, but nothing is like driving an amped up na motor. Plan on $10k to get ~450 that will last.

OP, I am making over 500 HP / torque and would be happy sending you build details. PM if you interested.

The short list, cam, lightweight rockers, 12.35 cr, FAST 102, electric water pump, underdrive dampener, Trickflow ported heads, forged rotating assembly, LTs, high flow cats, Corsa extreme, NW 102 ported TB, bigger injectors, FAST fuel rail, and other odds and ends. As you can imagine, the build was not cheap.

Oh, forgot stroked for more than 400 ci's.

LTCHAPPA

Add a cam and heads to get there but now your going internal. If you do just what I have you will be as quick as a C5 Z06

Verrückt ZR1

You won't be as quick as a C5 Z06 with stock heads/cam. Very wishful thinking.

grantv

If you mean these mods ("LT headers,cat back exhaust dyno tune,BlackWing air intake about 4-5 thousand, 354 to357 at the wheels") from post 5, I personally doubt that's enough.
The Z is a bit lighter, has deeper tranny gearing, bigger tires... you'll need more HP than the Z to meet it. I might be wrong...

Evil-Twin

A stock Z06 on the most accurate of the shop dynos out there, a Mustang is right around 351/355 rwhp and right around 349 /352 rwt.
A stock LS1 on the same dyno is right around 291 to 295 rwhp. So we are talking about getting to Z06 Hp? so we would need about 55/60 hp. Fairly easy with bolt ons.and a tune. Stock motors from the factory have a rich tune. so there is some good hp to be gained from just a tune. Ive seen LS1 with a tune see 305 to 308 at the wheels on a Mustang dyno. An increase of 10 to 15 hp with just a tune.
If you want bragging rights, a Dyna jet offers slightly higher numbers. But all dynos offer relative numbers ( meaning: use the same type of dyno to measure gains from added modifications.)

Its true that a stock C5 Z06 has the edge on my C5 that has bolt on mods but on the street the other 2 drivers were very surprised how well my car runs.
And as a matter of fact I did show what mods I had to the the other Z06 guys.My tuner guy said my car is putting down good HP. 354 then 357 at the second tune.
