I just purchased crate SBC 350 from jegs a Gm performance product . Well 6,000 miles latter i have 8% blow by on every piston and a whoping 12% on number 3 piston . What are the limits i should expect on a crate engine ? 5% or less or a bit more . I broke the engine in just like they said to do in the little manual that was sent with it . So i guess im looking at rebuilding a brand new engine that sucks with only 6,000 miles Of course they refuse to waranty the product as its not in a gm vehicel . I was even told my 78 280z put a strain on the engine as the engine wasnt made for a datsun . I asked what he meant by a strain on the engine he said the car is probably to heavy for the engine !!!!!!! Aparently a dumb ass so i spoke to someone else with no luck Just wanting to know what percentage of blow by i should be expecting to see or if all is normal basiacaly . Jason

Ok i posted a few things about stoping problems well i found i had a leaky booster . So i replaced it and finally got it adjusted and dang does it stop good . I almost threw myself through the windshield the first time i hit the brakes . So i really had to spend the day driving around learning to use my brakes all over again no more pushing the pedal roughly to stop . Now i have to lightly feather the thing , i didnt know a z car could stop so good . To bad they dont make a ABS unit for non abs cars that would be nice . Thanks for all the advice everyone it sure has helped . Jason

well my suspension is similar , i have the MSA sway bars adjustable end links . Dont order the end links a pain in the ass to adjust . I have the tokico lowering springs but only have the adjustable struts in the rear and the non adjustable in the front . Now to add to the stiffness or harshness of my ride i have the AZ car controll arms the fully adjustable ones . In the front there are no rubber or eurthane bushings anyplace all solid . Same goes for the rear all solid bushings . I had a problem with a fuel pressure gauge going bad about 2 weeks after i bought it i went through 3 cheap ones untill i gave in and bought the liquid filled gauge . Its lasted longer 4 months so far but the needled is starting to creep up the scale it never fully goes back to 0 psi it goes down to about 1 1/2 psi even when removed from the fuel line . I have my fuel pressure set to 7 psi but the gauge now says its 9 psi but i know better ive tested the pressure . I guess it determines where the gauge is mine is on the carb fuel inlet line about 2 inches from the carb . Jason SBC 350 super charged

I assume this is with a turbo . Would methanol injection also work with a supercharger ? Jason

Thats not a bad idea with the styro foam stuff ive used aluminum tape alot in the past gives me a good idea for a wide body kit once i try to add height to my existing hood scoop that is . first things first get the hood tall enough to clear the engine . If anyone wants to know i have a all fiber glass hood with a 4 inch cowl well its about 3 1/2 inches to short need like a 7 inch cowl as with a super charger there just is about 2 inches between the carb flange and the hood not enough for a proper air filter . Jason

Cool thanks for the info . ive searched past threads but wasnt sure about a sheet metal form as i wasnt sure if it would stick or not . There is a local marine store in town ill see what they have . Jason

Is it something ya can get at a fabric shop ? Ive looked around but no luck so far . Someone told me to use blue foam to make a shape for a mold i want to do for a hood scoop add on . Ive got a aluminum frame made thought of wraping it in sheet metal so it wont have any low spots in it . Is it possiable to lay fiberglass over sheet metal ? Jason

Well i do have a PCV valve hooked up but my brakes the "power booster " is also hooked up to the same vacuum line as the PCV valve . Doesnt seem to work so good for the pcv valve as it like to spit oil out anyplace it can at high rpms . Not a lot of oil but just seepage . Im haveing a leak down test done monday but ive only got 6 k on the entire engine . . I talked to a local drag racer and he said to just put breathers on each valve cover and not use a PCV as i use it as a daily driver . Or he said to put a T fitting of some sort to connect both breathers and vent them to a catch can . I had the same problem on the stock 6 cylinder and it had 2% leakage by the rings , but spit crankcase oil at high rpms . Jason

Is it better to have a negative pressure in the engine block by letting the PCV valve create a vacuum or to let it breathe through a breather in one valve cover . Ive heard that a vacuum in the block is a good thing some people say its not a good thing just wanted a few opinions before i finis running a few vacuum lines . Jason

Some gauges only come half full or at least i ordered a fuel pressure gauge and it wasnt quite full and its a autometer gauge . id call autometer and ask Jason

I have a buddy with a 92 Mitsubishi Eclipse turbo granted its not a z but most Mitsubishis that have turbos have Oil and water cooled turbos . The water cools of course via the radiator then they have a seperate oil cooler . Must work they still use it today . Heck they have gone as far as to have water cooled transfer cases on the all wheel drive cars and suv's . Id run a oil cooler seems ya cant go wrong if its been used since 1992 not sure about before that . Jason

Ok cant we all just get along just kidding not trying to start anything . Just want to ask again i really like the kit from arita speed . But im sure i cant afford it it was like 4 million yen whatever that equates to . I noticed MSA sold some flares like that but now only has the bolt on style flares not the kind in the pics on the link . Id like to get a set for my z . Is there any place one can get these or something like them . . as for the front id like to get fiberglass fenders is there anyone that sells a fiberglass fender that is wider then stock ? Jason

Where can one get flares similar to that maybe not as fat though Sure makes it easy to put in a wider tire . My tires are under the stock fender lip and are only a total of 9 1/2 wide tread is about 8 1/4 wide id like some that are about oh with a 14 inch wide tread . Jason

I had the same problem i just made the exhaust tip where it exits the rear of the car a bit longer . i pictured where the outer most part of the taillight would be if ya went straight down as if it were where the exhaust tip was and lenghtend them to that . Jason

I have Weiand 144 supercharger and it came with 1 fitting under the carb for a vacuum line . problem is i need 2 lines as i have my brake booster and PCV valve hooked up together with a T fitting . I dont like this it sucks . Anyone deal with this problem or have come across it . There is no other place to hook up a vacuum line and my demon carb has no fittings as its a blower carb , Jason

I did it yeah for the retard It took awhile but i got it ya have to click the link when i post a thread but its better then nothing . Thats why im a mechanic its much eaiser to fix a car then it is to post a pic !!! or it is in my case anyway . Give me a ECU reflash anyday easy as pie . Thanks everyone for the advice Jason

Im from melbourne florida the east coast . i had a blacked out window in the rear of a z once same as not being there but only was legal at least where i lived if ya had 2 outside rear view mirrors such as on each door .And if ya put louveres over it ya may never get stoped . id go without louvers to make a statement might look cool show some pics if and when ya do it . Jason

I have pics of my z saved to my desk top but cant figure out how to get them in a thread when someone wants to see what im talking about for a part or something . I found one spot but it said my jpeg image was to big or to many bites any and all help is welcome . Jason

Take a SBC 350 weiand super charger 144 series a demone 750 cfm blower carb and put a box on top of the carb flange that is 1 3/4 inches tall above the flange and covers the flange aera itself . Then extends to each side of the car and kinda angles down a bit to fit a 3 inch intake tube on each side . The air filters are not the question but my intake box wondering if its to short but i cant make it taller as it wont clear the hood . Ill try to post a pic if i can figure out how to get it on this thread jason

Thanks for the heads up im going to check out this "tuner shop" they claim they can get one for 119$ reman guess ill pu them to the test see how good a "honda tuner " shop can be when it comes to a datsun . Jason
