Please give me some feedback and feel free to ask...

niiiiicee!

you already got all the parts?

Yes I do, the things i need to order is the ECU and the Shimless buckets for the 1zz from japan. I have messured the intake side, so today i going to messure the exhaust side...

that sounds like damn big project! Keep us posted.

Thanks!
I will do my best!

Now i got some new pictures from my building last week.
Today i recived my secound hand os giken twin plate cluch and the new stand alone system from Link Ecu (storm)
I got MSD Igniter coils with multispark.
I´m going to messure the valve clearence and order 1zz shimlessbuckets later this week.
I also going to add an extra walbro fuelpump.

Here are the pictures.

5s block with 3rd gen 3s oil pan set-up? I wanted to do that but I thought I would have oiling issues

Did you notch the back of the 5s block? If not it won't clear the transaxle. There's a lot you have to grind off to clear. And you won't be able to use the stock bracing for the trans

Why do you think that the oil shuld be a problem? The 3gen oil system is better then the 2gen and 1gen systems.
And the oils isnt an issue on any st205 i´v seen here in sweden....





I have grinded it down alot. and last years setup i used and st202 3sge block bequas the old 3s-gte block where already bored so my pistons was to small.
I did the same to that block aswell as the 5s block.

I did some more grinding after this picture was taken to be shure....

I have started with some gearbox servicing.
I have felt som scratching on the 3:d gear.
Here is my progress so far.
Centerdiff pice is now removed



Cover for the 5th gear


The cover for the 5th gear is now removed. need to make a special tool to remove one of the gears, the other shuld be removed by heating



To be continiued....

Time for a small update again.
I´m going to shorten the adapterpice from the toyota flange to the t4 twin flange by 1" i dont need a that thick one, beqaus i´m going to add the external wastgate pipes to the holes in the WRC manifold, usualy used for anti lag.







Hopefully as soon as the gearbox is done i will install my os giken clutch and the box. Put it all back in the car and start creating the tubing and downpipe
And wire in the standalone ecu from Link.

thats one niiiice turbo you go there

2 things.

Why an older 1987 block?

and

2x fuel pumps is seriously awesome.

Has anyone put a 5sgte stroker in a gt-4 b4? (i assume they have its just not common, mr2's are more common)

The block is one just because the are alot cheeper, and the only differens from the later once is that they are stronger around the waterpump.
But i dont think i´m going to have that high temps in my engine so that going to be a problem.

The Walbros i think going to work great. last year on my last engine i think i was stressing my single walbro to the max. So this year I going to test 2 mounted together in the tank.

I´m also going to use GSC motorsport gen3 S1 cams instead of the once i said in the first post.

Long time since last post. but here is an update:







This is pictures of the compleated fuelrail, and the begining of the intake manifold. The pipes that are going to be the manifold is coming this week. so i´m hoping to get much more done next week.
Hope to post more soon

lookin good so far man!

Is that a gen 3 3sge intake manifold you are using?

I was thinking about that too, but I figured the runners would be too short, by getting a good shot like that of what they could look like aint bad at all.

what a great project and build, and i can see the pics at work SWEET!

Hello! I did this for its easy, and i hope the toyota engineers did there homework and calculated it right I´m going to update along the build so please have a look when i´m further on the road..

Thread brought back from the dead.. Nice build man, sign back on and give us updates ! If any
