Thread: Long Rod VE Engine build

Which btcc cars ran 88mm bores? sr20 cars?

x2 bro. $300 every time is getting a bit crazy.. over $1800 between me and Fize in the last year in just gaskets from Mazworx between 3 motors.

Charles did it back in the day, not sure what it was used on.

Iirc it was btcc. I may be mistaken it could have been another race class. It was a long time, iirc it was gtir blocks bored out to 88mm.

Stratton.

^That bad bruh? Man that's messed up. I understand the term you gotta pay to play, but that is ridiculous.

So generally everyone thinks 88 is pretty safe for NA?

I would think so but for me I would do 88mm instead of sleeve the block.

I'd do 90mm sleeve with 68mm stroke. NA

Yes, but I couldn't tell you if that is with the stock sleeves, or if aftermarket are highly suggested.
(I recall you've seen more than your share of aftermarket sleeve failures?)

well heres the thing, a few of us are trying to go bigger, the majority of us have had issues with a few people having success.

for the sake of 1mm id just stay 87mm.

there are guys out there trying to make bigger numbers and runner faster times.

i dont see 88mm being an issue at all with a 87mm gasket.

stratton.

you cannot safely go 88mm on stock sleeves. they will be way too thin....

Mike had failures on his sleeves bored to 87mm on a 550+ whp turbo DE-T (granted, I believe his investigation yielded some results that the block had been overheated multiple times in the past, so that may have contributed)...

I bored my turbo DE-T to 87.5mm and that's as far as Rebello was comfortable going to and as far as anyone should go... and that's being damn sure you have a good square block and all the prep and machining has been done properly.

Looking back, it would've been smart foe me to just sleeve it for future "expansion" but I wasn't in contact with Darton or any other places that would do it for a reasonable price in those days.

Nowadays for the cost of the sleeves ($350ish) + $500-550 Darton will sleeve your block and stand behind their work and the sleeves. You cannot beat that. And if you can you will probably be replacing sleeves often

Also, IIRC the Cometic Headgaskets for the SR20DE/T are all 88.5mm bore. So you use the same part number for an 86, 87 or 88mm engine the only thing that changes the HG configuration/part # would be the thickness...
