How is you low compression rebuild holding up?

Sweet numbers !!!. Can you email a copy of your graph to me ? My email is :

Yes. Do a search and you may run across KGP and Newport black and Tan? I think that the Newport was a GJ build but they engine issues may have been before GJ built the motor to low compression. There was a GJ build low compression set up which spun bearings without any FI. These were early cars and things have probably changed regarding reliability.

Hey Chris, I will be there for the Barret Jackson action in Jan. does that offer
go for anyone.I will be there 18th-21st.I plan on coming in to the shop.

Please stop by. It's a good idea to call first to make sure I'll be in.

Cheers,

Chris, Are you using the stock rods? I am oooooh so tempted to bump up to 550 RWHP. I think that drag racing, tranny wrecking, clutch dumps aside, the rods become a concern at or beyond this HP. Is there a consensus of opinion on stock rod max HP? I have only heard of a couple rods ever failing.

Also, has anyone ever lost a low comp build due to HP related mechanical failure as opposed to tuning issues? IE: bearings, rods, etc..

Yes, this car is using stock rods. We have disassembled engines producing more than 500 wheel horsepower using stock rods and have found no deformation. The stock rods are somewhat overbuilt and are being used in engines producing over 600 wheel hp which I believe is about the limit.

Oiling performance should not change much as long as proper clearancing is made and oil temperatures are kept within safe operating range.

Cheers,

Well we know that the pistons and oiling are the weak links, so for the engine builders out there, Do you think going forged pistons, changing the oil pump gears, and adding head studs is all that should be needed for the 500-550whp arena?

And would the 3.0l or the 3.2l factory block hold up better?

And yes, I am to considering the move to Turbo from HB-CTSC. (The crack pipe is calling my name, and it wont stop)

Like mentioned, the 3.0L blocks will definitely want to move to a MLS gasket to replace the factory composite gasket. The point of our testing above was to test the limits of the factory sleeve design. Unlike iron sleeved 3.0L blocks, 3.2L engines must be resleeved for aftermarket forged pistons in this application. Dave - for your intended application, the two blocks will not mater. The 3.2L short block will have a crankshaft with a slightly larger rod journal size. However, we have not noticed a difference between the two in the power handling range that you'd likely be looking at.

Cheers,

Simply speechless, nice job on building one fast NSX. Would it be possible to send me a higher quality version of this video? Also do you have any other videos of your car?

Cody,
Are you at 3.0L or 3.2L?
Great vids, I'm amazed by the spool up on that huge turbo.

Hey guys,

Just got in from a loooong weekend of wrenching.

I don't have anymore videos except for those that are on YouTube. Same username as what I am here, Tinker219 so search around!

I am at 3.0 Liters and after nearly 10,000 miles I am still at the same compression(actually slightly higher) than I was directly after my break-in dyno session. Truly amazing engine-work by Jim Elkins!

Cody,

What is an approximate cost for your Jim Elkin's engine build? (No one ever talks about that )

Your car is absolutely amazing!! Wow... so much power

I have been told $8500 - $13000 or up depending on your tastes
