i can vouch for mahle's in the DSM community pretty heavily used units

id hope the ring land on the turbo piston is stronger, but both are cast pistons so they can only go so far before becoming mushroom shaped striped slugs myself i like running a higher comp turbo motor but there are issues that come with it and someone that doesn't have the knowledge may get...

are you staying stock bore pistons? or going .020? if your getting over sized then you should provide the pistons numbered to bore each cylinder to each piston so the tolerances don't fluctuate from 1-6 in some cases with cheap pistons they may run smaller or larger then toyota and...

remember when you substitute toyota pistons for cheap aftermarket they may not have the same composition and may not hold the same power. ask around see if anyone had used those pistons before in our motors. read what this poster is saying here ill quote it for you Main Rod Bearing ( made in...

i would feel completely comfortable with eagles h beam rods at 600horse i built one motor 4cyl to 760 horse with boost and nitrious on eagles and the motor never failed. if i was gonna build a 7m for under 800 horse they would be my first choice. good strong forged units, good rod bolts, decent...

i would consider eagle rods to be one step below the OP's choices he gave us. usually eagle rods are about half the price of these other mentioned rods and ive had first hand experience with breaking these when pushing the engineering limits of an application 36psi also didn't help. but...

from personal experience I have seen that Crower is most concerned with strength mostly they don't spend a lot of r&d on other things like reducing windage on their rod cap designs and utilizing the best design for weight savings. generally speaking Crowers have been the heaviest of the high...

there are many different levels of engine machine work, with a Small business license I can go down town Spokane WA and get a complete 4 cylinder motor machined, cleaned, assembled with my parts for 200$ head rebuild is 125$ or I can go to a personal friends machine shop that does top notch work...

from what you stated it seems as though you used plastigage on your stock sized bearings and they were too loose of tolerance so you grabbed over sized bearings without any machine work? in my experience i have never been able to just jump bearing sizes without having something machined IE the...

rich why would you change the main caps i have not heard of us stretching these or maybe you have some info i don't. and what bearings would you source for this project? (rod and Main)

are you having the coating done in spokane? if so at PMS? i had 4 pistons locally coated with 2000* ceramic and cost 120$ so dont expect A+ work for those prices.

i saw that was more interested in 7m set

Ron were these available before you ordered? just curious on their R&D cost for developing another platform. William

what benefit do these bearings have over OEM or average clevite 77 type bearings?

my buddy had a supra so i bought one in Boston mass and drove it back to Spokane WA to then notice it had a BHG on the way home and then after fixing that noticed the car was being held together barely by rust and sold the car to a kid who blew it up 4hrs after owning it WOT everywhere upped the...

well if your buying a gte engine you might as well do the headgasket wheil the motor is not in the car. check the oil pan for any non-normal debree replace al hoses and vital gaskets while it is apart, clean everything you can having the head aluminum washed and decked for a nice metal...

couple good tips. take pictures as you tear it apart. take things off in sides/sections put bolts back in the holes you removed them from or grab masking tape and label them. another way is to take a big piece of card board and poke bolts through it and write with a pen or marker next to...

this is not a flame just an informational post for somone wanting to learn more , if you already knew this great if not hopefully somone else will benefit from it. your turbo never stops boosting it may be slowing down while you shift but the turbo really doesn't change speeds all that fast...

not having a car to tune on in almost 5 years. went to school and came back and now im looking at another supra for a tinker toy.

woot i feel like a noob again,
