RSX302 Future--Engine Poll...

[RSX302]

The LS 302 has been done. Using a LS6 block is the way to go.

A guy on this forum is doing a twin turbo LT-5. They draw a crowd with the hood popped. Nothing looks like those things. Here's one with a modded intake.



At the link there's a slightly used LT-5 for $3500. Those things were all assembled like race motors. Very durable motors.

Yes, that engine is a definite showpiece!

[ArtosDracon]

I like the idea of a LSx 302 with the twin turbos, would be pretty cheap too. GMPP aluminum block with 4" bore is about $1700, tough part would be the crank, though I'm sure someone like callies or eagle, maybe lunati could whip you up one pretty easily.

A .060 over 4.8 would be like 302. If you want an aluminum block, people have taken LS2 blocks over 1500hp and you should be able to find one reasonably cheap.

[Payton King]

glad to see you are still around.

I have a friend that has 9:1 Busch motor with 18 degree heads. It needs to be freshened but has a 5 stage dry sump and will handle 1200 HP pretty easy. It makes about 720 hp now. Complete from intake to oil pan. He also has a kinsler individual runner intake used on a Pontiac GTP car. Just like what Stielow put on the Mule when he was building it. He was going to twin turbo it as well, but never got around to it. Would you like be to check on a price? I think it will be well below your budget.

You already shot yourself in the foot with the Ford engine. Do it right the second time.

Mike agrees:

If the Ford 302 doesn't sell, that is exactly what I was planning on doing. Maybe not the Torino--even though I like them.

I would love to find something smaller for the autocross events. Most of those courses are tiny and just doesn’t do the bigger cars justice. (example; AC Cobra at optima Street Car Invitational)

Do I hear Sunbeam Tiger with monster wheels and 500hp!

There used to be a local here that had a turbo Boss 302 in a Tiger with fender flares, it looked more like a Cobra than a Sunbeam Tiger.

I just think a Torino is too cool because you don't see many and then none are Pro-touring (sorry to someone if they have done one)

American iron from the 1960's and 70's is always at a disadvantage on SCCA auto-x due to their size, most of the courses at done by a person with a Golf, S2000, or a Miata. If you find a course set up by a Corvette driver then real fun with big car is had.

Another home for that Ford, how about modifing one of the Factory Five GTMs.

[DynoDon]

I'd leave that Ford motor right where it is. Worry about it if and when you decide to sell the car! Everywhere in the car building hobby guys stick those lumps known as SBC's in anything and everything and no one says boo. But put a Ford or Mopar somewhere and they all get their panties in a wad.
I love the fact that you dared to be different. Quit worrying about it and keep having fun. And for those that don't like it

AS for sticking that motor in a Tiger with big wheels, I had one back in the 70's and it was unbeatable in Autocross back then. The problem is even a clapped out Tiger is gonna cost a small fortune now.

[ill steez]

I'd go with a destroked LS to a 302, and ditch the side graphics... maybe run some modernized Z28 graphics, since those originally came with the 302.

If you go looking for a new home for the Ford engine, take a look at the Maverick.
If you are looking to build a smaller than usual LS engine, you could always stuff a 4.8 Crank in a 6.0 block with longer aftermarket rods. Just keep in mind that the crank would be the weak link, but with the shorter stroke it just might be stronger than most would give it credit for. This would give you in the neighborhood of 327 ci. That would be a small enough increase that your current turbo system could probably still keep up.

That's an awful lot of work to build a 5.3.

[CarlC]

Build a 400ci+ LS3 block with lower boost. Tell everyone it's a 302.

What, you gonna call me a liar!?

Technically, if you build a 402 the first six cylinders are 302ci.

The last siamese runner plenum I saw like that went for $3,500. I do love the sound and looks of the LT5.

I vote LS power, if the turbo manifold are tubular you maybe able to weld on LS flanges as the bore space is close with minimal mods to the entire turbo system.

If you selling the long block what are you asking for it? Maybe I missed where you give the details and said how much you are selling the ford motor to offset the cost.

[Kenova]

I like to think of it as the better way to build a 5.3. The bigger bore improves breathing and the longer rods combined with the shorter stroke reduces the acceleration and deceleration forces the piston/rods see, along with a decrease in the side loads that are seen by the cylinder walls.

I really like what you have now, super creative, original, and rips on the track.

What about taking what you have and making it more badass, I think that would be the best bang for the buck.

You could probably get that motor out of there, drop some poundage, change the internals around and add another 250hp, and easy to put it back in. I think it would be awesome to have that motor turn 8500 rpm and make 950+ hp.

Coil over plug setup
New heads
Longer rods
220 - 221, whatever it takes

Oh yea, keep the sticker. Nothing better than some guy looking at you shaking his head and then you blow him away.

[MichaelUser]

I like the idea of a 1000HP duramax with a paddle-shifted Allison
The lswhatever is getting a little long in the tooth.
Ohh, maybe the new coyote ford motor..

Carl, you do have a way with words...LOL

As much as I would like to use an LS2 or 3 aluminum block, I'm hearing the downside to them is the stock cylinder sleeves above 600hp. Drops 30+hp not to mention major blowby. I hate blowby!

The LSx seems to be excessive for what I'm doing. I'm all for putting the money where it needs to be..but?

What about the LQ9 block? ($800new) Would it be better then the stock sleeves in the aluminum blocks at 700-800hp?

Set-up the LQ9 with forged parts (4.00x3.622 =364ci) at 8.8 or 9:1cr and 10psi non intercooled boost. With the LS3/L92 heads, this combo should yield a minimum 700hp/600tq.. (which is over 100 more tq then I had with the Ford) Get Texas Speeds LS3/L92 heads and 800hp is had at 7000rpm.

Hey Payton, Yea I'm still kickn'

I've been going crazy without the power pulls since the end of last year. I need to have Larry give me a ride in his...LOL

Here I fix my brakes and installed the new Rick's Tank and both have only had one or two outtings.

Send me some info/pics of the engine. Thx

what are you talking about? this is the only camaro id buy! the most apealing thing about this car is the motor setup and paint scheme it really sets it apart from all the other ls camaros
