I am just curious about Which EA82 Blocks Are better

87 gl carbureted Engine block Or the 92 loyal

Throttle body fuel injected engine block

Which of the two is better or is there any difference at all

I hope what I'm asking is making sense

Please help me out so I can figure out which direction I'm going on my next Build

FI blocks are 9.0 to 1 compression, whilst the carbys are 8.5. other than that....look at mileage and neglect to choose a block

Reason for me asking is 86 rx we've talked about it before

I bought the car and had a seized engine

so I pulled the heads and intake off that block

and put them on a carbureted block

The heads are like perfect condition no cracks whatsoever

So I'm running the multi port fuel injected set up with no turbo

Car runs great But I have like no top in after like 70 miles an hour

0 to 60 time The car hauls rump roast But from 70 to 80

the car has no power the vacuum advance is good

I've got a MSD coil NGK spark plugs and wires

I was wondering if I were to use the fuel injected block

do you think I can get that top in I am looking for

I am running 195/70R14's I should have a lot more power than what the car is putting out

what's your input thank you

the added compression would help in my opinion, also in my opinion i think the smaller compression number is further hampered by your larger wheels. even with a regular stock fi motor youre still going to loose top end due to its lack of sufficient power to push those wheels/tires

The carbureted block that I put in my car With the multi port fuel injected heads and intake

Only had like a hundred twenty nine thousand Miles

But I just recently blew the head gasket It was my fault

My oversized radiator Fell into the clutch fan

When I was splashing through some giant mud puddles

And I think I just got an air pocket And with the cold temperatures of the water

Cause me to Blow HG

And I have a nice low miles 93 Loyal Engine block that had a blown head gasket

I thought about putting that block with my heads in my car see how it does

 

The pic with the two Rx's - the grey 4 door sedan is my car the white one is a buddy of mine

I sold my factory wheels to him cuz I'll never use them

Close......Carb blocks are 9.0  (carbed 85, 2wd, sedans got a 9.5 block)

 

F.I. are all 9.5

and it is not really in the block itself is it ? More the pistons - so depends on how far you are going with a rebuild

So are you saying only the 85's that are carbed

are 9.5?

On;y the 2wd sedans in 85.

 

All the other carbed are 9.0

Thank you good to know I was under the impression

all the front wheel drive models had the 9.5

So this whole time I thought I was running a 9.5 instead I was running in 9.0

so I think it's best to run my 93 loyal block

so do you think that. 5 will give me that top and that I'm missing?

I don't know how a 7.7:1 comp engine runs so sweet off boost, am sure it would not go as well if there was no hair dryer at all in the equation. Sort of hard to believe just upping from 9 to 9.5 is gonna sort yours ??

 

I knew I should have kept that short from an 85 FWD !!

I think .5 on compression could make a difference on a 1.8

especially at top end since I'm running a non turbo multi port fuel injection setup

so thank you for your time helping me sort this one out
