first ever d build and i want some suggestions

[SPOOLIN]

exactly. have more fun, go 10:1

[cprtyler]

Ok 10:1 sounds like it will be fun. I'm wanting the bottom end to be bullet proof, is there anything else I can do with out resleaving the block?

[SPOOLIN]

no, there are band aids, but sleeves are the sure fire way to keep a turbo engine going for a lot longer.

[EmminoDaGreat]

True, if you're going to do it, do it once, and just have no worries, you can do a block guard but it wont save anything, just get you home

Ok one last question, rods and main bearings oem or acl

[Formally...]

Sorry to go off topic some but this is not 1995 anymore. The whole low compression for boost is a little out dated and is also more for large motors (v8's). With the tuning capabilities today you can be safe with the higher compression. I know that by the "book" you should do low compression with higher boost but I also know from "EXPERIENCE" and an engineering degree that higher compression and higher boost is very doable. The higher compression will have more thermal energy and in turn spool turbo quicker for better day to day driving. Also, you will need less boost to make the horsepower that is desired. Have to remember that motors normally blow up based on horsepower produced rather then how much boost.

Example for this thread. Using same turbo and accompaning parts.
9:1 compression motor on basic t3/t4 turbo will take about 20-22 psi to make 300whp
10.5:1 compression motor with same turbo will take about 17-18 psi and spool quicker and be at full power (due to lower boost) even quicker.

Examples of other motors I have done in the past few monthes
B18c1 10.2:1 comp 6262 billet turbo 19psi 565whp PUMP GAS
H22a 10.5:1 comp GT3076R stock head and cams 19psi 476whp Pump gas

Wow very impressive, I have heard of 10:1 compression motors being turbod, the only thing I was unsure of was good dd car. Thanks for the clairty youve made. Ill prob go with a 10:1 but really want at least 350-375 hp, if and only if u dont think I can do this on pump gas let me know and ill go alil lower, but as stated before about main and rod bearings what would u use in a high hp motor.

yeah sleeves are a must i wish i had some, all i had was a block guard. i cracked the block about 2" into cylinder 2. im never boosting without sleeves again

Does anyone have any advice on bearings, iv seen builds with acl's but was told that they were bad for boost.

Not bad for boost at all... I've never had a bearing fail under normal conditions and none of the engines I've built either. I had multiple bearings fail bout 5 years ago from a crank that went out of round.

Thanks as soon as I get my taxes in ill start getting to work om this amazing build

[JDMDA_1.7]

hell yea man.am glad you gonna boost it now bro.

Charles, James and Spooling know their shit. Seen them build some bad assery.
