ke70 16v 4age- blue or red top??

[dx_conversion_4age]

im doing a engin conversion on a ke70 wagon and wanting to put in a 4age!! at first i wanted to put in the red top 100 kw engin but everyone says to put the blue top in?? is it much easier or something?? i kind of know wat i need for the conversion but just confused on why the blue top is easier to install than the red top!! any help would be awesome thanx!!

[kingcorolla]

its no easier putting it in, its all just down to preference really. Some people like the blue top coz of the massive ports, and some the redtop, coz of the stronger block etc etc.

i reckon u should go with the redtop...

COZ THE BLUETOP IN THE WAG IS MY PROJECT!!!!

thenn we will race

[dx_conversion_4age]

so wat dows the lager ports do?? i thiugh that the red top was a better engin and had more power??

[RedMist]

The larger ports slow velocity and let the fuel fall out of suspension. IE less power. If you could pull 10k RPM the big ports would be perfect.

[overkill]

i used to be like that too,
worrying about power figures, just put whatever engine comes to you cheaper
you're making like almost double the power the 4k is putting out either way.

i never appreciated what an insane jump in power it was til the starlet got bluetop'd

u can even feel the difference 2-3hp gain.
yeah, so just get which ever engine comes to you at the lower cost,
theres no way you'll be disappointed

[Mr Revhead]

well overkill is kinda right here, you will be impressed which ever you go for!!
with the blue top, they are usually cheaper, easier to find, and more worn out!

the redtops are a little harder to find, more power, and usually not quite as worn...

so if your dropping in a stocker id go for the redtop, but if you come across a cheap bluetop fit that. if your planning major engine work going for the max na hp then id go for a redtop.

awesome thanx that helps out alot!! so with installing a 4age they need to be modifyied to fit into rwd is there a rwd 4age so all the mods don't need to be done!! any one know?? thanx

go blue top, parts are easier to find and if u want to go turbo at sumstage blue top would b the 1 to do it with.

hey man, i just put a bluetop in my kp starlet, got the engine complete (loom computer, everything) for $600, thought that was fair. All it took to put in was a another starlet crossmember with the engine mounts cut off, drilled 3 holes and it was in (2 for the engine mounts on the x-member, and one for the clutch cable to go thru the backing plate on the bell-housing), not running, but in. used a k50 g'box off a 3a powered corolla (its not gonna be a race car) which allowed me to used the stock g'box x-member and shifter hole... easiest conversion ever
Just the wiring a pain in the ass!!! Damn injection...

the tvis helps fight this tho. And there was a RWD bluetop, in the AE86 i believe, but hard to come across, and if u do find one it wont be cheap.

[badidas]

rwd 4age parts arnt cheap engine compleet with everything you need for rwd minus gearbox is worth 1200+
some places can adapt fwd bits to suit rwd config ie cut and shut intake manifolds probaby works out just as good and 3 times cheaper

[Mr Revhead]

want to go turbo at sumstage blue top would b the 1 to do it with

sorry incorrect.

the fwd is easy to convert to rwd, you can mod things easy, or i can still get most if not all of the parts needed new for cheap.

1200+ for a rwd 4age is a total ripoff!! unless that includes the install!

[mike simmonds]

wat u mean incorrect?

[Mr Revhead]

the redtop or silvertops are the ones to go for when turboing.
if you just wanna run 6psi then it doesnt matter as much, but if you want a 200hp+ 20psi engine then you need the stronger bottom end and the gze pistons.
sorry i didnt mean that previous post to sound as rude as it did!

[mike simmonds]

all gud! if u have a low budget the blue top is the best to turbo as u can just bolt a turbo straight on and use standard comp it also has slightly lower compression. of course the ze it better to turbo but he was asking wat one out of red top or blue top!

[Mr Revhead]

true, but if you start with a bluetop it can be false economy, may end up costing you more in the long run
as with most things car related it all comes down to money and application!

[MetalupYoAss]

shutup revhead, bluetops are best for turboing, just get your fuel sorted and you can get 200hp easy..

[suberimakuri]

bah.....you can turbo either.
bluetop is a nicer motor.

redtops just likely to have less kms, but it's boring as mud.

[Drifter4ag]

dead right.
Redtop=mud
Bluetop is the best for n/a power and for a low budget turbo engine with 200hp easily attainable on stock ecu
