you guys think its possible to achieve 600whp with a fully forged, bored, ported, and sleeved l61 with twincharged system combining a harrop tvs with a gt28r turbo?

i am saving up my money starting now through summer and i am taking the end amount and putting it towards my car. estimating to save about $7,500 with the 2 jobs i have currently.

Probably but why?

Nato09

why? bc i would like to walk covettes with my little underestimated 4-cyl.

Um it wouldn't be worth it.

if your looking for power that big...dont buy a TVS. f you insist on twincharging, then the M62 is a better choice to stock by, and you'd want a larger turbo...like a GT30..maybe GT35 even. idk..im not a turbo expert
regardless, the cheapest way to do it would be with a built head, forged bottom end, and a large turbo. Fueling is gonna be your choice. The end...

sorry but being a 2.2 guy as soon as i saw 600+hp and 2.2 on the same line i about died laughing, but sorry dude i dont think so, but don't let it stop you try what you want that's how new things get started

whether its a 2.2 or a 2.0 or a 2.4 has no bearing on the ability to reach those numbers FYI

Nato09

it will be worth it when i start racing for money.

i don't think so i think you would need a bigger turbo but the tvs should be fine

i'm sure a lnf could reach that easier than a 2.2.....

As stated, follow the build book. Build the top and bottom end. Then put a huge turbo on it.

Nato09

well sure you can reach it easier.. youre factory turboed. big step ahead of a 2.2

OMG this subject has been beaten to death.

Listen........ANY car can be fast. It all depends on how deep your pockets are. You can get a smart to run in the 10's if you really feel like it.

Also, I don't mean any offense by this, I'm just being frank, but you obviously are a newbie to car tuning. You need to do your research first. If, hypothetically, you were really going to go through with this, doing two different types of FI would not be your first choice.

Start watching vids and reading everything you can on people who have made four cylinders ungodly fast. Look at 9 second hondas, 9 second srt-4's, etc etc. See what the similarities are. Put thought into what they had to do to get to that level. Ask yourself questions like: What did they do to the physical aspects of the engine (boring, porting, etc), what kind of FI did they use, what boost are they running, what did they forge (answer: everything), what size intake/exhaust are they running, how did they solve fueling problems, etc etc. Just analyze what makes a four cylinder engine capable of running such low times.

orrr.. i can go an untaken route. i like the idea of twincharging. hasnt been done by alot of ppl.

fail.

there is a reason for that.

First youd have to swap out just about every oem drivetrain, engine, and suspension part on your car.

After youve concurred that youd have to convert to full standalone cuz no way the stock computers gonna handle anything near that. And since NO ONE has gone standalone yet, that will be a mammoth project.

So in short like everyone else has stated... just not worth it!

Nato09

okay, if not for the twincharging system, how about what umrdyldo said? just throw a giant turbo on it?

XM15

I say start off smaller first. Get all the engine work done and throw a GT28 into the mix. Get used to driving a faster car, then move onto a larger turbo, ect. Just my .02. A 600hp fwd car doesn't sound too friendly to a person who is used to driving an n/a 2.2.

This is really good advice. Doing the engine work is half the battle. You get that done then come back and discuss Turbo

roadrage06

orrr... you can dismiss anything i just said that quickly. with an attitude like that you will never know enough to make 600hp. i only spoke the truth dude, you've got some research to do.

Nato09

i had an idea that i wanted to explore. i appreciate the advice, but i dont appreciate you saying that basically i know nothing about cars.

06_ion2

wont happen for 7500 at all sorry ive already have that much in parts and with a blower and spray ill be luckey to see 450whp.. its going to take a hell of alot of work to get over 450-500whp just to be safe

Nato09

well.. i figured i could build a good turbo kit for 3,000, my friend has his own shop and connections to get pistons, rods, sleeves, etc. for cheaper than we would normally get it for. he would be doing the work for me for a decent price bc he is my buddy and the twincharge system has gone out the window so i will be saving a little money there to put into other parts.

roadrage06

Well, I'm sorry you took offense to it. Obviously you knew enough to know what question you wanted to ask, but it's hard to explain that I don't mean anything personal by it when you don't know how far off you are......because to know that you would have to know enough to do what it is you want to do. And that's how I know you need to do research.

I'm not trying to shoot your dream down, not saying twincharging won't work, but there is definitely more to it than you're proposing.

Nato09

you may be correct. i havent looked into the tuning aspect of it all yet. only parts and prices.

roadrage06

well, I wish you the best of luck.

Like I said, though, I suggest starting by seeing what the similarities are between the 4 cyl guys that are running high horsepower. Look for the tiny things like what they did with compression and displacement. And look at their fueling. what sets them apart from the guys only running 300hp or less.
