Yeah it would be the install I couldnt afford. I swapped a transmission, differential, engine, worked on tons of turbo kits....but never removed a head to slap on a HG. I would be afraid I would screw it up and ruin the engine. I got quoted like 800 for the install...I was like "wow".

 

LOL i dont pull magic, what area are you in? find yourself a compotent tuner that knows what they are doing, and they can make your car reliable w/ the stock HG.

 

good to have mechanic friends lol

 

Andy -- PSI is the variable most refer to on forums, but we should also be talking IAT and (n). 10PSI at 125 degrees is a lot less air (n) than 10PSI at 65 degrees. Obviously the more air you can pump into the engine, the better (up to a point). Knock is one of the biggest reasons folks have problems with blown headgaskets -- the pressure spike caused from knock far exceeds a high boost and high compression scenario. Two of the benefits of stock or high compression on turbo setup is throttle response and turbo spool -- something not shown on a dyno chart but experienced / felt on the street and race course.

I think you'll be close (or exceed) your goal, but a lot will have to do with the tune.

Best of luck!

PS -- Make sure you have a strong clutch

 

Yeah, I have been around turbos for 5-6 years so I know what you are saying....I just dont have a lot of experience with turboing hondas, the high stock CR was kinda scary at first but now Im reading where with a good tune people are making great power on the stock HG and making it last. I get conflicting information though, because some say " yeah, 15psi is fine on stock CR with good race gas " and others say " no no, thats too much boost keep it at 10psi". So, Im kinda torn here...I know 15psi on race gas is possible but I need it to last and not go boom on me.

I agree with you on the increased spool and throttle response you get when you keep the stock CR. Thats one of the reasons I wanted to stay with stock CR, because you can make a lot of power at a lower boost level and in my mind this is putting less stress on the engine even with the higher CR, and with a good tune there is no reason why it shouldnt last for a long time. keep the responses coming, thanks guys!

 

haha, I know you arent a magician but you know the ins and outs of tuning. The guy thats tuning mine is a local guy I have known for years....hes really good and uses a dyno dynamics so he can tune all parts of the map easily right there on the dyno. I told him I wanted 15psi on 110 and he said that was too much boost for stock CR. If I drove 12 hours to see you Im sure you would disagree but I have to work with what ive got ya know.

Tell me this, you think 15psi is too much boost on sunoco 110? I know you were using C16 on Phil's setup and you had a tubular instead of a log but I dont see 15psi being out of the question. let me know man, I trust your judgement.

 

its not that its too much boost, its more a question of when it will explode

 

lol, can you say that with 100% certainty?

 

No one can. Simple fact is that people blow motors completely stock, with basic 5psi SC kits, 10psi turbo kits, or 30 psi turbo kits. Use some common sense, what do you think has a higher CHANCE of blowing first....

Same can be applied to your situtation. If you have a motor on stock CR running 10psi or 15psi, which does your intuition tell you will blow first? Its pretty straight forward

Now if you can figure out which will blow first based on a formula...well lets just say you won't be driving an s2000

 

not in the slightest, but I'd have a constant load in my pants driving around on 15psi on stock compression
