Hello all,

I'm sending my bottom block out to Mike down at Laskey Racing and need some help choosing internals. I'm thinking of choosing some pistons a with a little higher compression than 9:1 but not too much higher (9.5:1-9.8:1 area) Also need help choosing between Pauter or Manley rods. I've chosen not to go with Eagle due to me wanting to rev high and have peace of mind. So here are some build notes.

Cliffs:

83mm or 84mm Benson sleeves (haven't decided bore yet)
9.5:1 CP pistons
Pauter or Manley rods
GSR crank (Might go get a LS crank from the junkyard if I'm not lazy lol)
ACL Bearings
OEM (TypeR) oil pump
Lower gasket set
Blueprint and assembly

Looking for 400-450 hp on 91 for the street and around 600 on E85.

Discuss.

 

84mm
either rod
ls crank

 

Any suggestion on a compression ratio?

 

9.5 - 9.8

 

83mm (leaves room for error)
9:1 CP's
Manley Turbo Tuff Rods
LS crank

 

If I don't go to the junkyard and get one will it make that much of a difference between the GSR and LS crank?

 

Forgot to mention, this car will be somewhat of a DD with a good amount of track time.

 

Mike built my motor. Started at 83mm GSR and after an incident I'm at 84mm. I went with 9:1 CPs and Pauter rods. I've got about 15-16k hard miles on a GT30R setup making 550whp.

 

leave room error, im comfused? anyway you go, the hp goal your looking for want be hard to acheive with parts.

 

I think I'm gonna go with a 83mm just in case something happens (which I hope not) Are you using a LS crank? If you could do it again would you raise your compression ratio?

 

Well, if I have a 83mm bore and something happens and I have to rebuild, I can bore to 84mm and not have to worry. If I have a 84mm bore and something happens and I have to rebuild and bore to 85mm, high boost would not be safe due to the walls being thin? But if the block is sleeved cant I still boost pretty high and not have to worry with a 85mm bore?

 

man most of us guys are running more than 10:1 on e85

also to be honest the stock block will make the power you see, and if you want to feel safer just do internals on the stock sleeves

 

E85 is kinda far from me. I'll get it if I have to though. As far as sleeving goes, I did save up the extra money for it so I might as well do it at this point.

 

83mm it is then, good luck.

 

good luck with it man

and just order e85 by the drum, and you will be good to go

by the way find a great tuner that good with e85, and this will be even better

 

I used a GSR crank. I would not raise the compression if I did it over again. 9:1 is working out for me great. With a GT30R once you hit that 0psi mark the car starts to pull even at part throttle in the city.

The only thing I would do over again is probably ditch my Full-Race AC setup as cooling with a half sized radiator in an integra just isn't very realistic for 95-100F temps or circuit racing.

I even had my fuel pressure regulator vac line come off once so I wasn't raising pressure with boost. It leaned out and detinated on me but that was like 5k miles ago and the compression is still perfect.

Mike/Benson put together some stout blocks!

 

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ ^^

are you on e85???

 

My set up will be going into a DC as well. I'm not to sure what I'm going to be doing cooling wise just yet. I want to get the motor in and see what my options are at that point. I'll be using a Lovefab ramhorn with a 46mm wastegate so I'm pretty sure I'll have to use a half sized radiator.

 

FAGGOL!!!!!upgrade fuel pump pronto.will give out of u if u run e85 and go boost crazy
