What's my current hp.. Educated guess

[Zrain25]

I'm in the the process of restoring a 89 mk3 has 140,000. Has a 3 in exhaust, intake, and a huge intercooler with hard pipes. What kind of hp is this thing makeing as it sits. The car moves good when the turbo spools I was thinking I'm at around 260 without a 3 in dp

And what are the cars I should not attempt to race, wrx, Evo ect and what are cars that these things beat my buddy has a cobalt ss with big injectors and intercooler, I would love to beat that thing.

I plan on getting Lexus afm, 550s, ct57 by next winter after engine gets rebuild.

Well, stock ct26 on roughly just below fuel cut is around 300rwhp and 320ish tq but if you're stock boost levels 6-8psi I'd say anywhere from 260-280.

No mention of what boost pressure you're running so there's nothing to go on.

 

[Zrain25]

Stock boost right now til next winter when engine gets rebuild with mhg And arps.


It looks like the previous owner had the exhaust shop make him a down pipe. Are there any welds in the stock one?

 

[Poodles]

If it's stock boost, you're not going to be making much more power than stock.

 

[Zrain25]

What a safe boost level I should turn it up to untill I can do mhg. And arps. Isn't fuel cut at like 8 psi

^+1 to that IJ. Leave it at stock boost till you do your rebuild. If you want it to last all winter. That's my 2 cents.

 

[Zrain25]

Lol ok. Now this is another question. I bought it with 145,000 no rod knock or anything. The guy said the head gasket was done from the guy he bought it off of so the previous, previous owner did the hg idk what type of hg he used or if the studs are arp.

The engine runs mint. So should I even get the engine rebuilt or just get the head machined and rebuilt and leave the bottom end? Or should I rebuild it all.

Car is not a dd. more of a weekend car once it gets painted

There's a spot at the front side of the head where you can see the gasket sticking out, if it's metal you won't be able to bend it there.

 

[Zrain25]

Do u know what side. Like near the alternator? Or some where. The engine isn't taken apart at all so I can't fit my diners in there to feel it

Other side from memory.

Do not ever trust what someone tells you about what the or anybody else has done to your car. Check everything like IJ posted pull the valve cover and if they are not studs then just don't run that motor past stick boost till you can start pulling apart. Sry I hope you were not lied to. But that's just my experances with past owners.

You were ALWAYS somebody
(it's just that you never mattered before)

^ haha IJ has jokes!!!

 

[Zrain25]

no wasn't lied to. I was never told if it was mhg or and studs. I know the head gasket was done. But idk what head gasket he used. I'm gunna tear it down next winter to be 100% sure.

A intake, downpipe, and exhaust got me to 235 rwhp @ 8 psi (auto)
