Hi
Atm I have a forged 383 stroker LS1 with a Harrop HTV 2300 running about 13psi. But I need a spare engine and more power. And need your help to find the right parts

-Budget is up to about around 20k, maybe up to 25k if I have to.
-I can do all the building myself so I just need the right parts.
-I need about 1000rwhp (manual trans)
-Fuel 98RON or E85 if I have to.
-Does not mater if its turbo, supercharger or NA. (nitrous is possible with NA)
-Aluminum block to save weight.
-I have the fuel system, oilpan, pulleys and accessories! So I only need the engine itself.

The most important thing is!
1. Not much lag. I need instant power. Dont know how a nice turbo setup will be on the this side?
2. Reliability. I have to be able to hammer on the limiter all day long.

Thats it. MPG, sound, idle, looks and so on does not matter! This is a pure race engine.

I am thinking about a LSX, RHS 454 block or something along those lines. And a big whipple or a nice balanced turbo setup. NA I probably have to go BIG cubes and a active Nitrous system?

Any have a good idea how to reach my goals?

I think a destroked engine with loads of rpm with a turbo setup. I could get specific but would be a long post haha.

DUDE....why on Gods green earth do you need 1000hp for drifting? Unless this setup is going into a Hummer H1 drift vehicle I really dont see the need for that type of power unless you just want the 1k mark for some personal goal. Been around the drift scene myself for a LONG time (not one to indulge myself) and most people overlook the importance of the other aspects such as reviewing every detail of suspension.

Even the heavier cars like the Supra and JZX100's typically have between 400-600 rwhp. JR Gittens Mustang was in the 700rwhp range as an example.

I definitely don't see a need for 1000whp. A simple LS3 or LS7 with a nice H/C/I setup will be fine. Both will be over 500rwhp.

Bacause I want 1000hp, thats why. Its my driving style. Why shuld I have what eveyone else have? I have been driving with 700-800hp in my little nissan and want more.

gtistile

Plenty of guys run 1,000hp.

This guy wants 1,000hp. I dont recall seeing in his OP that he wanted opinions about how much power he should make, but rather what the best way to make 1,000hp for that application would be.

Lets get back on topic. Wish I had more input for you!

Agreed

Thanks

Spinning 265 wide semi slicks in a car setup almost like a grip car takes alot of power.
Thats how far drifting has come now. Its all about speed, smoke and angle

I run at rpm limmit in 4 gear all the time. Thats 274km/h at the rear tires with semi slicks

To each there own lol. Proceed.

I would do a 427LSX, TFS 255cc LS3 Heads, and a Whipple 4.0L, if you absolutely have to have 1000rwhp.

gtistile

Does the 4.0 Whipple have fuel rails that allow it to make good power? Because they certainly shafted the 2.9 rails with baby feed size

Does the LSX blocks come in aluminium? I think they are about 130lbs more then the ls1? Not ideal for drifting

DEFYANT

Do an Aluminum Dart LSNext block.

LSX blocks are all iron.

As others say, hang back on capacity, anywhere in the 400+ range is more than enough. Even less would work.

IMO keep the stroke less than 4", build around a solid roller camshaft and top notch valvetrain to support sustained high rpm's, then a couple of 62mm or somewhere in that range billet turbos. Maybe even a pair of GTX3076's
They'll be robust and fast spoolin, or if they dont support enough power, something slightly larger.

Dont bother with a blower, it'll probably give no end of belt problems in that environment...that said there is a Polish drift girl running an LS and YSi and she seems to do well...of course you dont often hear bad news as opposed to good.

I'd say an LS2/3 or LSA factory alloy block would work jsut fine.

Given the hard use, piston oil squirters would be a good idea, which I believe LSA block has already

Slap a dry sump on it and away you go.

Steve, would you stick with stock cubic inch and bore / stroke? Or maybe go big bore short stroke like Clive is doing?

Key thing has to be get an engine builder who has the experience in building engines for your intended use. High rpms for longs periods of time will put a lot more load on the engine than a 10 second run up the drag strip!

Check out this guys 5.4L setup.....seems to be a nice high revving combo and close to your goals. I am sure with some E85 and some more boost this setup would hit your 1k mark:

Definitely a well thought out setup there ! And budget too using a factory crank.

How on earth did that thing make 500hp N/A

Here is his FI section details. The NA power is on an engine dyno FYI.
