This sounds like a good idea, probably easier and better than drilling. The argument for squirters doesnt stack up for me. I dont like the idea of taking precious oil away from the bearings to 'cool' the pistons... remember that physics tells us you cant actually cool anything down, all you...

Oh yeah, what are people doing about Eagle rods and no squirters? With no lube hole in the big end i cant see a lot of oil getting to the pin, or even the bores for that matter. The small ends have 2 holes drilled, but i dont imagine they will do much without oil squirters.

Good question. Im going to deal with the blowby gasses straight out of the crankcase, it is 'positive CRANKCASE ventilation' after all. I cant really see the need to bring the blowby gasses out of the block, and into the front of the cam cover only to pull it out the back of the cam cover again...

Oops, missed a couple of replies! Rollus, might i suggest you measure all the insert washers with a micrometer and order them by size before you start. i found the press fit section had a pretty wide tolerance, so i graded them by size before i started which makes it easy to maintain a good...

Thanks for the comments guys. No crank girdle for this one. Ive never had the crank become a "wet noodle" before, you keep the bearing clearances tight and lots of oil up to it and the engine will feel as smooth at 8000rpm as it does at idle. Main bearings arent something you see a lot of...

Today was a nice day to be working out in the sun so i final washed the block, gave it a quick lick of paint and dragged it inside into the engine building room. Also drilled/plugged it for front sump and plugged the main oil gallery between the pump and filter which i wont be using anymore...

My new cam covers are still a long way from finished, but you get the idea. I only just test fitted it on the head properly for the first time today! They were designed to be as slim as possible and also NO LEAKS. No rubber gaskets to get squished "just right", no juggling the torque on bolts...

I did some other work while the head was up on the CNC as well. Firstly the water galleries -usual missing #6 coolant drain was added, but i have also tried to address the airlocks inside the head by milling out the pockets so that the air cannot get trapped in this area. Originally those...

Hi guys, thought i should start a thread about the new engine i'm building for my Cressida (yeah yeah, its not a supra, but close enough!) For those that dont know, 7m's are kinda my thing, GE's in particular. I'm not really into turbos. What i do like is a nice responsive high rpm NA...

Here is my mate's Cressida at a local hillclimb where we took out 2nd & 3rd for the day, first time out for the car (and my mate). I built the GE in it a couple of years ago for him but it is still being choked by the stock ECU/TB/AFM. http://www.youtube.com/watch?v=VrtgVySQq4I (doesnt...

Oh hai! The Cressida forum is down so I need a new place to wax lyrical about the mighty 7m.... this looks like a good spot! I run a small aftermarket parts business in Melbourne, Australia making billet performance parts for Toyota's, mainly Cressidas and 7M/JZ engines. Work keeps me pretty...

haha awesome to see this running, i remember stumbling on the thread years ago was this the one with a 5m crank? also curious to know what broke, and i cant see any of the pics :(

the 5m-e has a chain driven cam and smaller harmonic balancer so is a fair bit shorter in the snout: which leaves bugger all hanging out the front, only a couple of mm engagement for the balancer: the 5m-ge is belt driven so probably ok in the snout but runs a narrower #1 main bearing...

sweet thanks

full aftermarket ecu with map sensor (no afm) has a fuel pump, not sure about injectors. prev owner claimed 270rwkw so... hoping its upto the task will be dyno tuned for afr's on (aussie) 98RON basically fuel/tune is not an issue, its more a matter of when do the stock units give up the...

hey guys i come from the land of the GE, built plenty of 7m's but not a boosted one yet. im a huge fan, got my own nuts 9000rpm race motor slowly in the build. i am doing a GTE for a customer, he is on a budget and im just wondering what the limit on stock (new) slugs is? it has some huge...

i am building a 85 x 85mm NA 7m with a 5m-e crank and custom pistons. i am going for 12.5-13:1 so havent bothered looking for another standard piston as i will need dome. it ends up at about 2.9lt i reckon 85 is the max limit of the block, but should be ok. the crank snout was a bit of a...

cams are 280 duration but only 8.5mm lift so hopefully wont be a problem. i am hoping to cut the exhaust valves back into the seat as much as possible to prevent crossflow during overlap, this should help again. also i am retaining the stock 27.5mm exhaust valves. i am only looking for top...

very nice work on the cnc chambers, i like it! interesting that the group A head has no squish areas, is all the swirl generated in the piston shape? i will be using flat top pistons in my 9000rpm NA build, so from what i know i will need to keep the squish pads in the head for some swirl...

what a fantastic find! i am jsut starting a very similar build, and thought i was the only one!! i am a BIG 7m fan, and an even bigger fan of highly worked NA motors (never been interested in going the 1/2j route). the new goal is to build a reliable 8000rpm screamer! i have an...
