Awesome... who did the build?

Who put it in the car?

Why did you go LT instead of LS?

[ZOHAN]

who did the swap is unknown, my dad and I built the engine in our garage and dropped it in my car. I didn't decide to go lt1 since it was already in it, but I like my lt1 since its kind of sleeper status and I dont want to become an ls fan boy lol. But I know gen 1 small block chevys pretty well so I love it.

Great answers. Love knowing the back story as well

Thanks popo, I really like the car and its my daily during the nice months of the year. No a.c. or power steering though!

Why not get a 52mm TB, and upgrade injectors with such a beefy cam? Mo POWA!

Also, didn't you post a pic of a 1st gen rx7? 1991 is second gen... if not start of 3rd.

Pics of engine bay please! :D

Will you put an angle kit, hydraulic e-brake, and lighten it up and drift it? PLEASEEEEEEEEE

oh is that what it is? How many rx7 lt1 builds do you expect to see on the same forum? lol.

[popo8]

hahaha.. the more the merrier. We have another member with a red one like swiggarts body style as well. Even used to have 91 swapped 300zx before as well.

it's a second gen, ill try to add some tonight. Would that be my biggest gains? Im looking for more power. I just bought 30 lb injectors, and a fuel pressure regulator that should solve any fuel issues. I also have a built 4l60e.

[MI6TA]

I know nothing about FPR's but from dyno's that I have personally seen from GMHTP articles where they tested many mods one by one and showed previous power and new power, and from the list you've shown those two jump out at me. Not huge gains, but anywhere from 8-15hp would be expected I'd think... Also, did you get 1.6 roller rockers? Those are like 7hp over 1.5's if they work with your geometry. EDIT, I see you listed your cam being for 1.6 so I'd imagine you got 1.6's already.

[MI6TA]

Also, according to solomon's site, when you changed the cam you should have gotten a power tune not just the basic tune.

[Swiggart]

Its a power tune, its just the first one he sent me. I know I need injectors, but then I have to get it re-tuned. I think ill throw them on sometime soon and then get a dyno tune.

My dad and I are building a 383 90 300zx as we speak haha. Good looking cars but heavy.
