yeah toyo men in the next couple months i will be opting for a faster engine and need some opinions or experiences with the choices i have proposed here and I am also still doing research while posting this, and which would be best to build on: any help would be appreciated.

Expected future gains 200-250hp

Application: EE90 rolla

a. 4efte
(with 5e head and block- wha would be the hp gain of this convert)

b. 20v silvertop, 20v blacktop
(maybe put the 7a head & block on it/ or turbo it)

c. 3sge

i say c,put the 3s

I second it*

will dat fit up?

3sgte or a 2zzge, or a boosted silvertop wit a blacktop head...

kidlex,3sgte and build from there u'll quickly hit your 250hp

actually u'll pass the 250 hp

3SGTE is ah good engine to begin your project with,you WILL NOT regret spending the money, dat will turn that EE90 into a small plane.

A more economical swap with less headache would be building a custom 4agte using any generation 4agze as the base. Throw away the sc and you can buy an aftermarket turbo manifold with a quality turbo. Upgraded intercooling and exhaust and you good to go up to 15psi with the stock ecu and injectors. When you feel the need for more power you can switch to external management and better fueling. There is also TONNES of support from the aftermarket and online forums for this sort of project.

3sgte was the first choice but funds didnt accommodate for that, sweet engine though

Anton that sounding good, but isnt 4agze hard to find

kidlex it can be found if u really want 1. let me know by tonight and tomorrow i'll see what i can find out

You'll have a lot more parts to hunt down if you're going with the 3S option and will definately have to move / build mounts. The 4AGE / 4EFTE is an easier swap but doesn't have the same potential as the 3S.

If you are going for a 3S, get the 3SGTE if you can. It opens up a lot more options.

There are a few EE90 cars on the road with the conversion.

I agree wid anton. If its 200-250 u looking for u might as well start of with a platform that will be able to handle it. The 7a and the 4e/5e will not take a big set of boost unless u build it from the bottom up. The silver top 20v is the better to boost as the internals are a bit stronger than the black top who's internals were lightened. But not to stray the original toppic i agree wid anton the 4agze 16v small port is pretty bullet proof so you can turbo it and surely make yah 250. If you also want you can stay supercharged it starts at 170 hp and is easily tuned with the upgraded aftermarket supercharger pulley to 190. might be cost effective. Just remember brakes and suspension we doh want u to end up in a lamp post. blesssss.

Be warned, supercharged boost is addictive. Boost from off idle to redline. With the torque delivery you feel like you driving a na large displacement engine.

tte boy get a set of rear disk there put down, also have my front sway bar to put on as well yet to get a strut brace though but i will work on that piece by piece she will come together.

Anton do temp the mind dey day dreaming is a bad thing

by the way do u all know any one who boosted the 4agze leaving the super charger

Zeriam u got d pm dredd

a ported 3s with cams can meet your target. Turbocharged, even easier. No replacement for displacement

there was a twin charger kit by HKS that had a clutch that would switch the supercharger off at 4000 rpm onto an already fully spooled t28 turbo which would then take u up to 8500. It was good for 250 hp at only 8 lbs of boost. check fensport.co.uk they have done it all.

thinkin bout goin the 4agze way, later may want to swap gze head for the blacktop as it breathes better do you all think this may work even though one is a 16V and the other is a 20V

There were discussions around the pistons being different on the 20V from the 16V to accomodate the tight tolerance with the 5 valves. I don't know if the problem will exist with the GZE. You'll have to be certain that the piston doesn't come into contact with the valves on the 20V head.

There are some issues to consider when contemplating swapping a 20v head with the 16 gze head. You would have to fabricate an intake plenum capable of holding the boost levels you want. ITB's and boost are a tricky combination. The aftermarket support in terms of cams and valvetrain parts are MUCH easier and cheaper to get for the 16v than the 20v head. IMO the swap, while a worthwhile idea, just isn't worth the trouble from a practicality and overall potential standpoint.

P.S. My last car was a ae92 with a 4age 20v and my current car is an ae111 with a 4agze. Both cars are insanely fun, but in different ways. The 20v was designed from the ground up to be an excellent NA engine and imo should be used as such. the 4agze was designed specifically for boost and with the right parts and tuning the sky's the limit.

was readings up on the twin charged setup for the gze it seems a good upgrade for the future decreased lag then into boost that sounding good, jus asking but whats the max hp a gze ever did,

Was wondering though which of these applications would aslo be best for dex was thinking the gze

The gze with the supercharger intact would be the best option for dex. Virtually instant torque delivery.

thanks for all the advise fellas, but is there a specific place to buy the oil for the sc12 scharger or can i can i pick this up and what type of gearbox oil should i use as well
