Toyota 1UZ in a impreza

[Guest boostcut]

i know a guy and il even tell you his name!!!!

its geoff nicholson from dyno power in birch ave tauranga.... he actually uses wrx sti pistons and bore sleeves in the early 1uz block and has made his own billet crank and custom big $$$$ rods and his 1uzwhich hapily pulls 10000rpm and makes around 450-500hp is in a sa22 rx7 which has a rather shallow engine bay but the good thing is you can modify things to make it fit.... the biggest prob is the sump and the intake manifold but toyota quads and a custom sump SHOULD be on the to do list. theese motors are brutally wide aswell. because of the quad cam arrangement they are nearly as wide as fords 5.4 quadcam

If he using the big dollar parts and EFi and reving out that much he should be dissapointed with anything under 500hp.......

there are things called restrictions in motorsport champ... like throttle size etc.... mite wanna read the rules of sportsedans....

Wow my simple post got a bit out of hand but thanks for the contructive replies to some of you guys. Im still going ahead with this conversion. Yet to decide if ill stay with the auto and go supercharged with a GM471 or similar through the bonnet or go 5 speed manual with 8 throttles, altho i dont know if having 8 throttles will increase or decrease the power.

yea the guy that built that red rex did it in 2 weeks! not a bad effort but it was done very rough and he had a bit of trouble with gearboxes. as for the drivetrain falling out that is total shit. He had to move the front cross-member and steering rack back 50mm to get the motor in, which when going around the corner at the top of pots hill at +140k caused it to bumpsteer sending the new owner of 15mins into the paddock. I was talking to my certer and apparently a bit of shit went down with it being certed. A slight dodgy or gray area. If your going to do it, do it properly. good to see your doing plenty of r&d on it. good luck!

you will obviously be running a link or something to run throttles? so the individual throttles will make an impressive gain in torque up top as they will be short

forgive me if wrong... but wont ITB's increase top end at the expense of torque?

[Guest boostcut]

i did this on my fxgt on a dyno. had ITBs on a 3 inch long manifold and had alot higher torque at 8200 as compared to the 5 inch manifold at the same revs....

search tuned intake runners on google i wrote a tech thing on 4age.net a while ago about it.... had pics and a video to help explain

hell man...what do you do for a living?

[Guest boostcut]

mechanic haha

[wrx_lou]

heh. thought that'd be the case. you seem to have a fair bit of useful information . Anywhere i would of heard of? my cars in TGA at the moment.

[Guest boostcut]

probably not.. i have worked for eastland toyota, bay nissan and a performance rotary/engineering workshop called avenue autoport, at the moment i work for a wakeboard/ski boat/car mechanic workshop called asplin motors

[wrx_lou]

oh ok. My cars at a place called Dtune Motorsport.

[Guest boostcut]

d tech? thats a mint place aye...

[wrx_lou]

yeah sorry d tech! really? I hadnt heard of them. Was originaly going to go to hitech, but my mechanic's good mate with the guy there.

[wrx_lou]

lol thats why i couldnt find any info of them...was searching for the wrong name.

*face palm*

thanks for that mate

Ive decided to fit a 1UZ into my mates 1995 subaru legacy wagon. I will build his car as a bit of a trial befor i do mine. Ive also spoken with a certifier regarding the red WRX that crashed. Apparently his steering rack was mounted lower which caused it to bumpsteer. That combined with going to fast probly caused him to crash. Ive i move the rack down i will move the whole crossmember down and therefor avoiding bumpsteer issues... fingers crossed.

or engine up maybe with a bonnet bulge or skimmed tappet covers/intake manifold
