1990 NT front case

[JamiesTSI]

Dose anybody know if the 1990 Non-Turbo 2.0 liter use a different front cover?

I have one on a engine stand and can not seem to get the front cover from my 1992 AWD to match up to all the bolt holes. Thanks.

maybe your 92 was made after may of 92 and has the later design engine as opposed to the pre 92 engine.

 

[Mike1992]

Sounds like your 92 has a 7-bolt motor and your 90 is a 6-bolt. Some parts such as the front case aren't interchangable.

 

[JamiesTSI]

My original block has a 6 bolt crank and the oil pan does not have the indention that the seven bolts have.

Should ALL 1990-1992 six bolt non-turbo/turbo front covers interchange?

 

[Mike1992]

Should ALL 1990-1992 six bolt non-turbo/turbo front covers interchange?

Yes they should, if they're 2.0

I have a new water pump on the NT block, the one that's on the stand. I also noticed that the corner of the front cover from my 92 turbo block was hitting the bottom of the water pump and would not sit flat on the block.

 

[timloomis]

sounds like either a front cover issue or a block problem.could be the wrong front case or the wrong block.are you sure the block is out of a 90 dsm?theres a lot of engines that look like the 4g63 but are not,i.e. 4g37,4g67...

 

[JamiesTSI]

Good thought Tim are there any tell-tell signs of it being a 2.0 4G63?

On a side thought I allready have the 2.4L stroker crank, pistons, and rear main seal installed. I started working on the timing belt side. I have the water pump on and both the timing belt tensioner pulley and stationary pulley along with the motor mount for that side.

Started on the front cover and ran into problems.

Yes, look for a flat spot above the dipstick hole, you should see the engine code stamped there. Turbo and non turbo will both say 4G63.

 

[JamiesTSI]

My block is stamped:

G4CP
V466065

Any ideas?

 

[JamiesTSI]

I found some info on Road Races web sight. It looks like the 93-95 Elantra had a engine code of 4G67/G4CN. The block I have is stamped: G4CP.

Is it a Elantra block and if so could it be used as a 2.3 stroker block?

Thanks.

 

[alexg1323]

4g67/g4cn are 1.8 dohc engines that look identical to the 2.0, they have a slightly smaller bore. G4cp is a 2.0 block identical the the 4g63 non turbo these are hyundai codes. Elantra comes with 1.8 and 1.6 liter engine so your not going to be able to do much with an elantra engine unless your trying to make a honda

One of the applications for that engine:

1992 - 1998 Hyundai Sonata 2.0 DOHC-16V (Engine: G4CP)

They should all be 6-bolts. Not sure why the parts don't fit though.

 

[timloomis]

i know a few poeple on here are pissed because they though they had the mitsu block,and ended up getting a hyundai one instead.my buddy had a 93~ elantra with the 1.8 4g67,and i couldnt tell the difference looking at it.hyundai may have done something to the front case to make it their own,so you couldnt buy mitsu parts for it.i imagine you could stroke it and just get a front case off an elantra.thats all i can come up with.

 

[JamiesTSI]

The engine code on the block is stamped G4CP. Would the Elantra and Sonata blocks be the same?

The crank that came with the block is a six bolt crank. I measured the bore and pistons, they where the same size as the 1G 2.0 DSM pistons and bores.

Anybody have any Hyundai parts laying around? Namely the front case.

So whats everybodys thoughts on strokin this bad boy?

 

[pneumo]

I went to importperformanceparts.net and cross referenced part numbers between a 6 bolt 4G63 and your G4CP. They share the same part number for the oil pump. They also use the same main and rod bearings, too, so it should be just as good at building into a stroker as a 4G63.

I wonder if you got the right oil pump? Where did you get it from?

 

[JamiesTSI]

Thanks for checkin those part numbers.

As far as the oil pump its-self goes they are the same between the two blocks. Its the front case that the oil pump bolts to that is different.

I can get a 1G DSM front-case to mate up to the G4CP block. The only problem is some of the bolt holes are not lined up.

That's what I meant, oil pump=front case. When you buy an oil pump they send you the whole front case.

I can get a 1G DSM front-case to mate up to the G4CP block. The only problem is some of the bolt holes are not lined up.

How far off are they? Would it fit if you enlarged a few holes a little bit? Or do you need new holes in completely different locations?

 

[pneumo]

I had a couple more quick thoughts. Was your block made with balance shafts? I remember seeing a different part # for oil pumps/front case without bshafts. Is the water pump the only thing keeping the front case from bolting up? Maybe it's the wrong water pump?

 

[JamiesTSI]

The 1G DSM front case will fit tight on the G4CP block. The only thing I had to do was nip that little lip on the bottom of the water pump off.

Most of the the bolt holes could be enlarged to make it work BUT, two of the four bolts that hold the oil filter housing on are WAY off.

Yes it had balance shafts. I took the rear one and cut it down.
When I removed the front case from my 4G63 I noticed that the oil pump gears where riding on borrowed time. So I cut the counter weights off the rear balance shaft and will be running it as such. I refuse to run the stubby shaft anymore.

I am having one heck of a time finding a used front cover with the oil filter housing. Any-body know where one is?

 

[alexg1323]

i have some rebuilt 6 bolt oil filter housings, for external oil cooler. if you need that

 

[gameGSX45]

Ha, I am in the same predicament, have been for the last few months. Well, I know that you are going to need the G4CP front cover along with the oil filter mount...that is for sure. But did you say that you got the belt tensioners on??? My mechanic just told me he was unable to use the belt tensioners off of my 91' GSX...I called Slowboy yesterday and they are looking into it for me, should have some more concrete information this afternoon.

 

[JamiesTSI]

You need the 7 bolt tensioner.

You could use the 6 bolt tensioner if you made a spacer for the bottom bolt on the tensioner.
