Turbo'ed stock longblock track times ?

Trying to decide between a HCI set up or just add a turbo to the stock long block in my 91 LX.

What kind of times are you guys running with stock long blocks, larger TB, Long tubes, MAF.

How much coin would i be looking at for a turbo kit for the stock long block along with supporting parts ?

are 11's possible with traction ? single or twins required for deep 11's

I'm thinking TFS heads,systemax intake, custom cam and click off some high 11's in a coupe 5 speed for around $2k. If i could go faster with the turbo set up on the stock long block and roughly the same cost I'd be in.

Thanks

I've recently had a HCI combo car, a Procharged car with HCI, a KB car with stock long block and then HCI, an NA 349 and now a turbo 331 stroker. I can tell you that the price of the turbo kit wont be the end of it. On all three of my power adder cars I have had a custom tune. All three went to different tuners. All three tuners quoted me around $500 for a tune and chip. All three charged me over $1,200 when it was all said and done.

Right now I still have 1 car with a NA 349 stroker, 1 car with a 306 and HCI and the turbo car with HCI. The HCI car is my favorite. Not as much power as the stroker HCI or the turbo car but it runs great and is a lot of fun on the street and on the track.

Tons of little unforeseen problems $ with the turbo car. The turbo will lay down some big numbers but will also nickle and dime you to death. Plus the HCI car was the easiest to maintain and drive fast at the track (all of them are man trans cars).

Go with the HCI. If you are still not happy you can always hit it with a small shot of nitrous at the track or add a turbo or sc later. Just my 2 cents....

Thanks for the input.

From what i was seeing the turbo kit alone was around $2500 for the smallest kit( not sure what that yields on the track) then the fuel system, tune. Probably more power than a HCI set up, so tremec/g force tranny required, rear end ect $$$$

Guess I'll stick with the original plan

TFS 170 heads
Systemax
custom cam
long tubes and all the other supporting hardware.

last car i went nuts and dropped a HCI carbed windsor, tremec tko, 31 spline rear, drag suspension ect ect. When it was said and done it was so far from stock it wasn't as fun to drive on the street anymore.

This time I want it to be easily converted back stock, so untouched shortblock just unbolt the heads,intake,cam and put the stock stuff back on.

I have the On3 Turbo kit. $1780 to the door. Still had to buy injectors, fuel pump, adj regulator, maf, wideband and injectors. If I had it to do over I would stick with HCI and spend the rest on suspension! Then if it wasnt fast enough I'd add a power adder.

Good luck with your build.

thats moving for sure. How much did he have tied up in the set up ?

Seems once you start modifying your always wrenching. The faster you go the more time in the garage.

I'm not really sure. He used a MPT70 and a set of shorty BBK's with cheap ebay WG and BOV. Then a set of 42lb injectors matching MAF, fuel pump and regulator. He said that he has more money in the tranny than the whole motor/turbo set up. He ran those numbers on 12lbs.
He has had some problems with leaking headers and fuel pump problems as well.

wow how much boost can a stock shortblock handle on pump gas ? After years of playing with N/A rigs my eyes opened wide when I started playing with a turbo diesel dodge. I gained literally 50-75hp by sliding a fuel plate forward,adding a $25 boost elbow and adding a section of 4 inch exhaust pipe.

Cheapest HP i ever acheived. With a larger turbo and some injectors i'd gain another 100hp for $1500 or less.

Thius got me to thinking about the whole turbo deal on my notch.

I've run my car at 14lbs with pump fuel no intercooler on 93 octane. I am running a carb and aluminum heads though.

There's no single answer to that, too many variables. What are your goals?

Btw, I've dealt with two turbo combos, both back roads hillbilly tuned years ago before there was much dyno tuning going on. One combo died somewhat quickly, but was probably stupidity on the two bozos tuning on it. The other turbo combo only ate cheap c4's, but never required any more major work once it was together. A good dyno tune should make things much safer. And I'd run more octane if possible (maybe with higher boost when you want more fun).

Scotty we need more power!!!

HCI vs turbo....which do you think will win? I think HCI is a waste of money compared to a turbo setup. All motor is outdated and over-rated
