Hello, I have a b18c1 with pr3 (usdm b16) pistons and p72 head with type-r cams. I want to run a high compression turbo setup. The setup I was thinking of is boosting 6lbs only but get a smaller turbo, something that spools quickly and is ideal for 6psi. According to c-speedracing, my compression is 11.37 and a stock type-r is 10.6. I see turbo type-r's all over h-t. I plan to run pump gas as well, so it will be tuned with crome or hondata.

some questions:

1. What turbo should I run? I want to run something with max efficiency at 6psi
2. How much power am I looking at at 6psi? dyno graph of a high compressoin turbo?

 

Im not going to pretend to know the answer to this but I know it can be done. Check out the guy on here named Tony the Tiger. He's running 10.5:1 CR and 9200 rpms so he should be able to help ya.

 

i know theres some high comp turbo guys on here

 

 

Theres nothing wrong with a high comp. turbo motor. And theres nothing wrong with the broad power band you obtain from this setup as well. I've been runing an LSVTEC with 11.5:1 CR and 10lbs. Of course 91 pump all the time and extensive tuning with an AEM EMS. Never had problems with detonation, etc. As long as you know what your doing as a tuner and how minor adjustments effect the motor as a whole you will be safe. One more thing, do not cheap out on parts and tuning. If you do not know how to tune take it somewhere to someone who has massive experience. I see too many posts on H-T nowdays where people are melting pistons, throwing rods, etc. just because they decided their own tune is good enough. Patience is a virtue when it comes to building a fast car. Just make sure you have gone thru everything before driving the car hard.

 

No reason to go with that high of a compression and a turbo, especially since it's a daily driver on pump gas.

True. It's not needed but very fun to work with and a great overall experience. It's one of those builds that make you think about everything you do. If money is an issue I would say definitely don't do a build like that, just turbo a stock bottom end a be happy on the street.

 

Yeah I tend to lean towards the cheap bastard safe side when it comes to cars.

I say go with 9:1 pistons and a big fatty turbo.

thx for the input, i already know that tuning is the key, learned it the hard way

there are many great tuners around here in the bay, so im not too worried about getting a tune. msmotorsports, do you think that hondata s200 or crome would be a sufficient enough for this setup? and how many hours or runs on the dyno did you put in?

actually he is running 11.5:1 c/r with a gt28r at 14psi

No point in buying Hondata when you can get Crome for free...

I already know that, but the problem is finding a dyno tuner for Crome, not many shops with a dyno tune crome because if something goes wrong with the program, the shop has no one to call for help. When hondata tuned, when something goes wrong with the program, they can call hondata themselves and find answers within minutes.

 

i ran 10.2:1 compression on my gsR block, the ups are the spool up time when compared to lower compression, we were running 10 psi for medium boost and were hitting 350 whp

 

high comp and turbo = un reliable and prolly ganna blow in few months


i say spray on it, n2o loves compression

Haha they don't have very good customer service at all from what I hear. Besides that I doubt anything will go wrong with either program. It's either going to work or not work.
