Basically I can get a good deal on a GSR shortblock (AEBS, Pauter, Ross 8.5-1 pistons).

If I use a b16 head, should be around 8.3-1 compression. How will this perform as a street motor, I'm running a precision SC50 for now.

Also the shortblock is a spare from a race car being parted out, ran on meth. Would the tolerence of the motor be to loose for the street??

Thanks

 

LAG

 

Going out in the cold without a jacket does NOT give you a cold.

Girls do NOT give you coodies and,

Low compression does NOT create lag; improper turbo selection does.

When Jeff's website is up again (Boosted Hybrid) you will find a great article in the tech section on this subject. Reading it would help your understanding.

I run 7.8:1 in a street car and would gladly trade compression for boost.

 

sc50 with a 3inch exhuast wont lag any more with 8.3:1 c/r than it would with 9.8:1

 

compression does not effect lag

tune it right and you wontknow the difference

 

Higher compression increases the thermal efficiency of your engine. I personally like 9.5:1 to 10.0:1 Compression ratios.

 

Its little low for my liking, mine is around 9:5:1

Thats kinda of what I am thinking,

I run a B16 right now and will probably just build this motor 83mm 9-9.5 to 1 when the time comes.

I guess I am just falling for all the hype of the GSR botom end being far superior to the B16......... Hell, I'm only shooting for around the 400WHP range

I might even try it on stock sleeves and put the other 1000 somewhere else

 

The extra torque of the GSR motor is well worth it for a street car.

 

Try doing lsvtec. I always have good luck with them. currently I'm running gsr block with ls crank and b16a head. I have a back up block which has old darton open deck sleeves with 81.5mm 9:8:1 weisco pistons and eagle rods. I might be selling that block though. good luck with whatever you do. I would go ls block since they're cheap and you can find them easy.

I like how this guy thinks. So then where do coodies really come from??

Does anybody have a rough idea in the difference in torque between a GSR and B16, given the same build and turbo set-up.

Basically using the same B16 head and same compression ratio

oh really...what if I ran 2.0:1 compression, I would need to run some puny little turbos?

 

Well... there are limits to just about everything, your intellect notwithstanding!

 

If you have no info to share, please stay the hell out of my thread

 

7.5:1 on a D series here.
No problems driving off boost.
At all.
Your 1.8 should be just fine.
