Hey guys, so this is now a new shortened version of my build thread after photobucket took a dump on everybody by changing it's hosting rights

 

shared this on a few different forums but thought I might aswell throw it on the supra forum since it's a jz place

 

so here goes, lets wind the clock back 4-5 years at the begining of basically a nut and bolt rebuild haha

 

my bone stock s14 silvia sr20de n/a import from japan

got bored so decided to do a new engine build since i had a fully sorted chassis that was very capable of handling more power

 

 

bought a load of new parts for the build, going 1.5jz so a 2jz block and 1jz head

so i had bought a 2jz ge block, had it machined to take oil squirters and turbo oil feed, i sent my block to a motorsport company in dundee scotland

 

unfortuantely i wasn't to know how bad i'd end up

 

i wanted a new set of pistons in the block and bearings so the compression ratio would be right+ refreshed and since i don't have engine building precision tools i thought i could turst them

 

my block came back with deep scoring in the bores in some cylinders, weather that was there before i don't know but it should have not been returned to me like this from an engine builder

 

deep enough that my finger nails would go inside and catch

 

when removing the bearing caps to try remove the pistons to see if i could hone them out going on advice from other engine builders i'd realised some of the 'new' bearings were also damaged

 

on an engine only turned over by hand a few times

i'd bought other parts from this company also which turned out to have issues

 

i was told i'd marked the block with a screw driver and it's my own fault.....yeah so basically i had to start from the begining minus the money i'd paid so far

 

i'm not to mention his name as i'd not like to be done for slander for making damaging accusations but i guess you just learn who not to deal with in the motorsport trade!

 

thankfully i didn't use the engine as it would have burned oil and all sorts

 

so.....cut to a few months down the line, i had no money and a half built car after selling my 1j+r154 setup and piling all the money into the parts for the new build

 

i got in contact with DY engine services, dave yandell, he suggested oversizing my block which means new pistons and rods again and another set of bearings+arp studs etc

 

i just went with it and put it on my credit card because i had to! otherwise i'd have an expensive useless tin on wheels

 

 

dave worked his magic, block hot tanked and painted, .5mm oversized so bores were like brand new

engine run in on dyno and oil changed correctly

 

box developed a noise so changed it, abc couldn't have been more helpful with aftersales advice, probably best company i've dealt with

 

image144 by Jonny McIntosh, on Flickr

 

back onto dyno after driving around for a while making sure everything works for a base boost map

 

image145 by Jonny McIntosh, on Flickr

 

image146 by Jonny McIntosh, on Flickr

 

pretty good for just base boost :D

 

image147 by Jonny McIntosh, on Flickr

 

changed onto the good stuff

 

image148 by Jonny McIntosh, on Flickr

 

went for a drift day with just stock 1 bar of boost which is wastegate spring pressures, boost controller off

 

image149 by Jonny McIntosh, on Flickr

 

had so much fun, went down with my mate stevie to crail and we spend the day chasing eachother

 

i was rusty as that was my first time drifting in 2 years with a whole new engine/box setup and a new alignment and anti roll bar setup

 

completely different car to drive, it's 100x easier and such an animal now, the boost comes on so hard so fast too

back to dyno and had boost turned up

 

image158 by Jonny McIntosh, on Flickr

 

image157 by Jonny McIntosh, on Flickr

 

the car was mapped up to 2 bar of boost and made something over 600hp, unsure on exact figure due to wheel spin but it's insane.

 

so i need to go back with some 265 r888's now to make sure i can get grip and we will do a proper power run

 

as for now, the car insurance was set to expire the day after mapping so it's just been put into storage since august, i've had other priorities to sort out just now

 

it'll get back out in 2018 and insured and ready to rock around march/april time

 

but for now it's just needing some overfenders on the rear since the 1/4 was reshaped by stevie's s14 during a drift session and it'll mean i can run stupidly wide rear wheels

 

 

 

 

also dumping these in here for my own reference incase i'm ever stuck without them, boost controller references

 

p1: wastegate pressure no boost controller

p2 - 1.2 bar, 40 gain =25

p3 - 1.5 bar = 50 gain =25

p4 - 1.8 bar = 60 gain =25

p5 - 2 bar = 65 gain =25
