Suggest a turbo for 300+rwkw out of a 4age

[70XIN]

Turbonetics = China made, US assembled turbos. They make fairly decent numbers, but are pretty hit-and-miss, a fair few of them die for no reason at all. Very popular in the states, because they are a percentage cheaper than garrett, but buying one here in aus they don't make any sense.

Btw 1.8 stroker is just a 7AFE bottom-end with a 4A head. You should be able to get a 7A from almost ANY local wrecker.

70XIN, I have no idea why people grout blocks. I heard of it before but never looked into it.

So, here's a datalog of an evo'ish car, running a 4g63.
Look at graph 1 logging throttle position, RPM, and boost. After flooring from cruise it goes from 70kpa to 160kpa/9psi in less than a second. That's at only 3000rpm, and boost tops out at wastegate pressure of 14psi on the graph. Dude reckons it does 24psi by 4400rpm but I KNOW that amount of boost can be brought on sooner. Turbo's about the same size as a GT35 so it'll crack 300rwkw on a 2l for sure and with not much lag at all.

Ok so Garrett is the way to go in Au, fair enough.

Come to think about it the cars ive seen the turbotronics on have all be from yanksvill...

I dunno dude. A guy I know has a 9sec VL with a 2JZ.

I asked him about the turbo.
He said turbonetics. I said why not garrett?
He said it's better, makes more power and spools a lot quicker.
It's only the opinion of one guy but he's happy with his turbonetics. and there's borg warner turbos as well which they claim spools quicker than garrett stuff. and garrett based units by precision.

CYB make a full kit. crank, rods, pistons (low/high comp options).

ITS NOT CHEAP, but if you have the $$ behind you to attempt such a feat then it maybe worth considering.

Haven't heard anything good about turbonetics stuff... Stay with garrett, borg warner or trust and you'll be home free...
I would think a normal 7a bottom end would be fine for a cubes increase in this application... your obviously going to have to rebuild what ever engine you chose anyway.. so forgies and rods is a given..

This all raises the next question.. what GEARBOX do you plan to run.???
you can get away with skimping alittle if theres no plans to run big rubber, but what ever you chose still has to be well strong..

ill be running a W58 gearbox, aparently they are good for up to 350KW

Found one place that makes the 4a to w5* bellhousing, if people know of any others post here so i can check them out.

[--Redwork--]

W58 and 350 kw.. really.???.. Once again it come down to application... and why are you chasing 300 anyways..???

300rwkw out a 4a is goin to be useless for anything other than drag racing.. and then a manual box would be pointless.. Unless its a dog box or a lenco/g-force/richmond/liberty ect..

[Sam-Q]

it's hard to even put an estimation on what a gearbox can handle, it's the shock loads that kill it. Also who makes this one bellhousing you found? if it's dellows then avoid it like the plauge

[PRIMRK]

Ive found the AJPS one


any one used this befor?
