LT1 swap??

[MikeGyver]

what is hard about the cooling system?

Nothing, it's just a radiator and 2 (or just 1) PCM controlled cooling fans.

now i all i need is to buy the intake manifold...

You need to buy an LT1 intake manifold you say? lol buy the one I just so happen to be selling

That intake is sexy. :greg:

 

[MikeGyver]

Yeah, right after I had it blasted and powdercoated I found a red CNC ported LT4 intake and ended up using that on my build instead, so now it must go.

what is hard about the cooling system? anyone have any pictures they can show me or upload. i would like to see this swap done thanks

The hard part is fitting it in the cramped engine bay.

i cant run the stock manifold. or so im told. that the stock one wont deliver enough air. i have to run the LT4 one. if that is a lie then i already have the stock one. will the stock intake work?

 

[4Runner]

that is a very sick looking manifold thou

Just whack 5" off the long side of a ford dana 60, and run the c&c 14 bolt hubs, your axles would end up around 64" and 63" wide. lt1 to a chevy trans, then a driver drop t-case.

narrow on 1 tons

I've been extremely active in the LT1 community for the past 3-4 years and I did very extensive research when I built my motor. The LT1 manifold is not the bottleneck and actually does very well, nobody replaces them. The LT4 intkae differences are very minimal. The main thing people change is the throttle body and port out the inlet holes in the manifold to match. A dual 58mm throttle body is going to create less of a pressure drop than the stock dual 48mm one. It might net you 20-30hp or so. I'm using a stock throttlebody.
The LT4 manifold might have to be machined so it sits betweent he heads and the ports still line up somewhat (which they probably won't very well). Don't waste your money on an lt4 intake, if you must then get a throttlebody.

What heads are you using?
What are all the parts you're using for that matter? what compression ratio?

 

[4Runner]

i am running the stock heads but they are running comp cam honey combed springs, knew valves dont remember how big but i went as big as possible, port and polished, i am runner the 11.1 compresion, the pistons are sealed pro or some crap like that. running comp cam int 290 exh 307, derration .05, int 230 exh 245, valve lift int .510 exh .540, running eagle 700 hp connecting rods, and crank, crank is perfectly balanced and weighs 43 pounds. and im just going to reprogramb the chip. the stock chip. the guy that is helping me with all of this is from salt lake. and he thinks the motor will be pushing around 550 hp. i hope it get at least 500 hp.

 

[MikeGyver]

It's all in the heads... You might have a hard time getting over 450 engine hp unless the stock heads are ported extremely well and the cam matches.

 

[4Runner]

i ported them my self. the guy im doing all the stuff threw really liked how they looked. they are alot better and bigger then they used to be i know when i put it together after i did that the car was way faster just from that. i would think i could get 450. but i dont know. i have alot of work into it. what kinda mpg do you get?

 

[MikeGyver]

Just got 21mpg highway w/o the turbo on, which is pretty good considering my motor is low compression (9.1:1) and I was driving 75mph and it's an auto trans. It'll gain a couple mpg with the turbo back on. Around town is usually somewhere around 16mpg.

 

[4Runner]

thats about what i should get with this motor in the 4runner. thats better then what im getting now. that will be nice. when i get all the things together i will start a build thread
